“你有没有注意过？医院配电室的低压柜上标着 MNS，工厂车间的常写 GCK，小区配电房里多见 GGD—— 这些一串字母的配电柜，到底有啥区别？为啥不同地方要用不一样的？其实不用怕术语，这篇就像‘解密’一样，用大白话讲清 GCS、GCK、MNS、GGD——10分钟读完，下次路过配电室，你也能分清里面的柜是哪种。其中错误和不足的地方欢迎大家批评指正！”

　　Have you ever noticed? The low-voltage cabinet in the hospital distribution room is labeled MNS, the one in the factory workshop is often written GCK, and GGD is commonly seen in the residential distribution room - what is the difference between these series of letter distribution cabinets? Why do different places need to use different ones? You don't have to worry about professional terminology. This article is like 'decryption', explaining GCS, GCK, MNS, GGD in plain language - read it in 10 minutes, and next time you pass by the distribution room, you can also distinguish which type of cabinet is inside. We welcome everyone to criticize and correct the mistakes and shortcomings! ”

　　一、概括的话有以下几点：1、GGD是固定柜，GCK、GCS、MNS是抽屉柜。

　　1、 In summary, GGD is a fixed cabinet, while GCK, GCS, and MNS are drawer cabinets.

　　二、固定柜

　　2、 Fixed cabinet

　　1、GGD是固定柜，固定柜是不说模数的（只有抽屉柜或固定分隔柜用模数来表示，这个后面再说），GGD交流低压开关柜具有机构合理，安装维护方便，防护性能好，分断能力高等优点，内部的断路器、接触器、继电器等电气元件直接固定在柜体框架或安装板上，缺点是回路少，单元之间不能任意组合且占地面积大，不能与计算机联络。（以上为光伏GGD并网柜图片）2、GGD 的 “优点”：为啥很多地方愿意用它？没别的，就是 “实在”—— 便宜、结实、好修，特别适合 “用电稳定、不折腾” 的场景：①便宜省钱：因为是 “固定式”，没有抽屉那种复杂的轨道、联锁零件，成本比抽屉柜（比如 GCK）低一半都不止。比如小区配电房、农村小工厂，预算有限，用 GGD 能省不少钱。②结实抗造：柜体是用厚钢板焊的，跟 “钢架柜” 似的，放配电室里用十年八年都不变形。里面的电线接头、开关都是固定的，不像抽屉柜有插拔接触点，不容易松、不容易坏。③电工好修：不用学复杂操作，随便找个电工师傅都能修。比如开关跳闸了，打开柜门一看就知道哪儿的问题，拆几根线、换个零件就行，不用琢磨 “抽屉怎么抽、插头怎么插”。3、日常维护：①擦灰尘：配电柜容易积灰，半年用干毛刷扫扫里面的灰尘，不然灰尘多了会短路跳闸。②看接头：打开柜门，看看电线接头有没有变色、发焦（正常是铜色，变色就是发热了），发现了赶紧拧紧螺丝，防止烧起来。③试开关：偶尔拉一下总开关、分开关，看看能不能正常跳闸，别等真出问题了开关没反应。4、应用场景：“用电稳定、不常换零件、预算有限” 的地方，基本都选它，适用于中小型配电室、小型泵站、传统制造业车间等对扩容需求低、预算有限、配电需求简单的场所。三、抽屉柜

　　1. GGD is a fixed cabinet, and fixed cabinets are not expressed in terms of module (only drawer cabinets or fixed partition cabinets are expressed in module, which will be discussed later). GGD AC low-voltage switchgear has the advantages of reasonable mechanism, easy installation and maintenance, good protection performance, and high breaking capacity. The internal electrical components such as circuit breakers, contactors, relays, etc. are directly fixed on the cabinet frame or installation board. The disadvantage is that there are few circuits, and the units cannot be arbitrarily combined and occupy a large area, which cannot be connected to the computer. 2. Advantages of GGD: Why are many places willing to use it? There's nothing else, it's just "practical" - cheap, sturdy, easy to repair, especially suitable for "stable electricity usage, no hassle" scenarios: ① Cheap and cost-effective: because it's "fixed", there are no complicated tracks or interlocking parts like drawers, and the cost is more than half lower than drawer cabinets (such as GCK). For example, in residential distribution rooms and rural small factories with limited budgets, using GGD can save a lot of money. ② Durable and resistant to construction: The cabinet is welded with thick steel plates, similar to a "steel frame cabinet", and can be used in the distribution room for ten or eight years without deformation. The wire connectors and switches inside are fixed, unlike drawer cabinets with plug-in contact points, which are not easy to loosen or break. ③ Electricians are easy to repair: there is no need to learn complex operations, any electrician can fix it. For example, if the switch trips, you can easily identify the problem by opening the cabinet door. Simply remove a few wires and replace the parts, without worrying about how to pull out the drawer or plug in the plug. 3. Daily maintenance: ① Wipe dust: The distribution cabinet is prone to dust accumulation. Use a dry brush to sweep the dust inside every six months, otherwise too much dust will cause a short circuit and trip. ② Check the connectors: Open the cabinet door and check if the wire connectors have discolored or burnt (normally copper colored, discoloration indicates heating). If found, tighten the screws quickly to prevent them from burning. ③ Test switch: Occasionally pull the main switch and branch switch to see if they can trip normally. Don't wait until there is a problem and the switch doesn't respond. 4. Application scenario: In places with stable electricity consumption, infrequent parts replacement, and limited budget, it is generally chosen. It is suitable for small and medium-sized distribution rooms, small pump stations, traditional manufacturing workshops, and other places with low expansion requirements, limited budget, and simple distribution needs. 3、 Drawer cabinet

　　GCK、GCS、MNS都是抽屉柜。以下为逐步解析1、GCK开关柜?GCK柜体外形尺寸：宽度：400/600/800/1000/1200mm深度：800/1000mm高度：2200/2300mm

　　GCK, GCS, and MNS are all drawer cabinets. The following is a step-by-step analysis: 1. GCK switchgear? GCK cabinet dimensions: Width: 400/600/800/1000/1200mm Depth: 800/1000mm Height: 2200/230mm

　　一、先搞明白：GCK 到底是个啥？你可以把 GCK 理解成 “带抽拉抽屉的大型配电箱”—— 就像家里衣柜的抽屉，每个抽屉里都装着控制电器的 “小零件”（比如控制车间电机、空调的开关、保护器）。平时这些抽屉推进去，跟柜子连在一起供电；要是某个抽屉里的零件坏了，不用拆整个柜子、不用断总电，直接把坏抽屉抽出来，换个好抽屉推进去，几分钟就能恢复供电 —— 这就是它比 “固定死的配电箱”（比如 GGD）方便的地方。

　　1、 First, let me clarify: what exactly is GCK? You can understand GCK as a "large distribution box with pull-out drawers" - just like the drawers in a wardrobe at home, each drawer contains "small parts" that control electrical appliances (such as workshop motors, switches for mall air conditioners, and protectors). Usually, these drawers are pushed in and connected to the cabinet for power supply; If a part in a drawer is damaged, there is no need to dismantle the entire cabinet or cut off the main power supply. Simply pull out the damaged drawer, replace it with a new one, and push it in. Power can be restored in a few minutes - this is where it is more convenient than a "fixed distribution box" (such as GGD).

　　二、GCK 的 “过人之处”：为啥不用固定配电箱，非要选它？①咱们拿 “小工厂生产线” 举例子，你就懂它的好处了：坏了不用停整条线：比如车间里某个电机的开关坏了，要是用固定配电箱，得先断总电、拆接线，修 1 小时生产线就停 1 小时，损失钱；但?GCK 是抽屉式，提前备个好抽屉，抽坏的、插好的，10 分钟搞定，生产线几乎不用停。②能 “搭积木” 改大小：要是工厂想加个新电机，不用买新柜子 ——GCK 的柜子是拼起来的，像搭乐高一样，加个新抽屉、接个电线，就能给新电机供电，不用砸墙挪柜子。三、哪些地方会用 GCK？看这几个场景就懂不用记复杂分类，记住 “中等需求、要方便维护” 的地方，基本都选它：①小工厂 / 作坊：比如做家具的工厂、织衣服的纺织厂，有几台电机，但不是特别高端的生产线 —— 坏了能快速修，又不用花大价钱买高端柜。② / 酒店：控制空调、照明、电梯的电箱，比如想在节假日多加几盏灯，直接加个抽屉就行，不用大改电路。③小区配套设施：比如小区的水泵房、换热站，里面的电机控制柜用 GCK，物业师傅不用太，也能换抽屉修。

　　2、 GCK's' standout feature ': Why not choose a fixed distribution box instead? ① Let's take the "small factory production line" as an example, and you will understand its benefits: if it breaks, you don't have to stop the entire line. For example, if the switch of a certain motor in the workshop is broken, if a fixed distribution box is used, the main power must be disconnected and the wiring must be removed first. After repairing for one hour, the production line will stop for one hour, resulting in a loss of money; But what? GCK is a drawer style, with a pre prepared drawer for both damaged and inserted items. It can be completed in 10 minutes and the production line hardly needs to stop. ② Can 'build blocks' to change size: If the factory wants to add a new motor, there is no need to buy a new cabinet - GCK's cabinet is assembled, just like building Lego, adding a new drawer and connecting wires can power the new motor without having to smash the wall or move the cabinet. 3、 Where will GCK be used? By looking at these scenarios, you can understand that there is no need to remember complex classifications. Remember to choose places with "moderate demand and easy maintenance": ① Small factories/workshops, such as furniture factories or textile factories that weave clothes, have several motors, but not particularly high-end production lines - they can be quickly repaired when they break down without having to spend a lot of money on high-end cabinets. ② Shopping mall/hotel: Control the electrical boxes for air conditioning, lighting, and elevators. For example, if the shopping mall wants to add more lights during holidays, simply add a drawer without making major changes to the circuit. ③ Community supporting facilities: such as the water pump room and heat exchange station in the community, the motor control cabinet inside is made of GCK, and the property manager does not need to be too professional, they can also replace drawers for repair.

　　四、平时怎么维护？跟照顾家里抽屉一样简单不用请，电工师傅看一眼就会：①定期拉一拉抽屉：看看抽屉能不能顺畅抽拉，有没有卡住 —— 就像家里抽屉轨道别积灰，不然拉不动。②擦一擦 “接头”：抽屉后面有铜片（跟柜子通电的地方），时间长了会氧化发黑，用干布擦一擦，不然接触不好会发热跳闸。③检查 “锁”：GCK 有个小设计 —— 抽屉没推到底，或者柜门没关好，就通不了电，防止触电。定期试试这个锁好不好使，别让它失灵。2、GCS开关柜

　　4、 How to maintain it normally? It's as simple as taking care of a drawer at home without hiring an expert. An electrician can easily pull the drawer at a glance: ① Regularly pull the drawer to see if it can be pulled smoothly and if it's stuck - just like the drawer track at home, don't accumulate dust, otherwise it won't move. ② Wipe the "connector": There is a copper sheet behind the drawer (where it is connected to the cabinet), which will oxidize and turn black over time. Use a dry cloth to wipe it, otherwise poor contact will cause heating and tripping. ③ Check the 'safety lock': GCK has a small design - if the drawer is not pushed to the bottom or the cabinet door is not closed properly, the power cannot be turned on to prevent electric shock. Try this lock regularly to see if it works, don't let it malfunction. 2. GCS switchgear

　　GCS 和 GCK 都是抽屉式低压柜（都能抽拉抽屉换零件，不用断总电），但就像 “同一的中配款和低配款”，核心区别在 “通用型、耐造度、适用场景” 上，咱们用工厂电工的实际视角，白话讲透，选的时候不踩坑：一、直观的区别：抽屉能不能 “随便换”（配件通用性）这是两者核心的不同，直接关系到电工后期维护的麻烦程度：GCS 的抽屉：全国 “通用款”就像 AA 电池，不管是南孚、金霸王，只要是 AA 型，都能放进同一个玩具里。GCS 的抽屉是全国统一尺寸（国标规定），比如你上次用 A 厂家的 GCS 抽屉，这次坏了，随便买 B 厂家的同规格抽屉，插进去就能用，不用等原厂家发货。电工省心的就是这个 —— 不用攒一堆不同厂家的备用抽屉，备一套通用的就行，紧急修的时候不耽误事。GCK 的抽屉：“厂家专用款”就像某些的手机充电线，只能用自家的，换个牌子就插不上。GCK 没有全国统一的抽屉尺寸，每个厂家的抽屉导轨、插头位置可能不一样：A 厂的 GCK 抽屉，插不进 B 厂的 GCK 柜里，甚同一厂家不同批次的抽屉都可能有点差别。电工维护时得记着：“这个 GCK 柜是 XX 厂家的，抽屉只能找他们买”，万一厂家没货，就得等好几天，耽误生产.

　　Both GCS and GCK are drawer type low-voltage cabinets (both can be pulled out to replace parts without disconnecting the main power supply), but just like the "same brand's mid-range and low-end models", the core difference lies in "universal type, durability, and applicable scenarios". Let's use the actual perspective of a factory electrician to explain it in plain language, without stepping on pitfalls when choosing: First, the most intuitive difference: whether the drawer can be "easily replaced" (universal accessories). This is the most essential difference between the two, directly related to the difficulty of electrician maintenance in the later stage: GCS drawer: National "universal type" is like AA batteries, whether it is Nanfu or Jinbawang, as long as it is AA type, it can be put into the same toy. Inside. The drawers of GCS are of a nationally standardized size (according to national standards). For example, if you used a GCS drawer from manufacturer A last time and it broke this time, you can simply buy a drawer of the same specification from manufacturer B and insert it to use it without waiting for the original manufacturer to ship it. The most worry free thing for electricians is this - they don't have to save a bunch of spare drawers from different manufacturers, just have a set of universal ones, so they don't have to worry about emergency repairs. GCK's drawer: "Manufacturer specific" is like some brands of mobile phone charging cables, which can only be used at home and cannot be plugged in by changing brands. GCK does not have a nationally unified drawer size, and the drawer rails and plug positions of each manufacturer may be different: A factory's GCK drawers cannot be inserted into B factory's GCK cabinet, and even drawers from different batches of the same manufacturer may have some differences. Electricians need to remember during maintenance: 'This GCK cabinet belongs to XX manufacturer, so we can only buy drawers from them.' If the manufacturer doesn't have the goods, we will have to wait for several days, which will delay production

　　二、能装的 “电流大小” 不一样（适配负载）①简单说：GCS 能扛更大的电流，适合 “大电机、大负载”；GCK 更适合 “中小电机、小负载”：三、“耐造程度” 不一样（长期用的稳定性）1、比如工厂电压偶尔波动、电流突然变大（比如电机启动时），两者的抗造能力有差别：GCS：“骨架粗、铜排厚”，更耐造GCS 的柜子框架用的是更厚的钢材（像家里的厚铁门，不容易变形），里面的送电铜排也更粗，哪怕电压突然波动，铜排也不容易发热烧蚀；抽屉的轨道是金属耐磨款，用十年抽拉还是顺滑，不容易卡。GCK：“简化设计”，适合稳定小负载GCK 的框架钢材薄一点，铜排也细一点，更适合电流稳定的中小负载（比如照明、小水泵）；要是长期用在电流波动大的地方（比如重型工厂），时间长了铜排可能会氧化发黑，抽屉轨道也容易积灰卡顿。总结：一句话分清两者GCS 是 “抽屉通用、能扛大负载、耐造的中高端款”，适合怕停机、想长期省心的场景；GCK 是 “抽屉专用、适合中小负载、经济实用的基础款”，适合预算有限、负载不复杂的场景。简单说：要是工厂有大电机、修的时候耽误不起，选 GCS；要是就几台小电机、预算不多，选 GCK。3、MNS开关柜(低压配电柜里的实力担当)

　　2、 The "current size" that can be installed varies (suitable for load) ① Simply put, GCS can withstand larger currents and is suitable for "large motors and loads"; GCK is more suitable for "small and medium-sized motors, small loads": 3. The "durability" is different (stability for long-term use). 1. For example, occasional fluctuations in factory voltage or sudden increases in current (such as when the motor starts) result in differences in their durability: GCS has a "thicker skeleton and thicker copper bars", while the cabinet frame of GCK is made of thicker steel (such as thick iron doors at home, which are not easily deformed), and the power supply copper bars inside are also thicker. Even if the voltage suddenly fluctuates, the copper bars are not easily heated and burned; The drawer track is made of metal wear-resistant material, which can be pulled smoothly after ten years and is not easy to get stuck. GCK: "Simplified design", suitable for stable small loads. The frame steel of GCK is thinner, and the copper bars are also thinner, which is more suitable for small and medium-sized loads with stable current (such as mall lighting and small water pumps); If used for a long time in places with large current fluctuations (such as heavy-duty factories), the copper bars may oxidize and turn black over time, and the drawer tracks are also prone to dust accumulation and jamming. Summary: In one sentence, GCS is a "universal drawer, capable of carrying large loads, and durable mid to high end model", suitable for scenarios where people are afraid of downtime and want long-term peace of mind; GCK is a "drawer specific, suitable for small and medium-sized loads, economical and practical basic model", suitable for scenarios with limited budgets and uncomplicated loads. Simply put, if the factory has large motors and cannot afford to delay repairs, choose GCS; If you only have a few small motors and a limited budget, choose GCK. 3. MNS switchgear (responsible for the strength of low-voltage distribution cabinets)

　　一、可以把 MNS 理解成 “低压柜里的‘高端定制抽屉柜’”—— 比之前讲的 GCK、GCS 更精密、更抗造，比 GGD（固定柜）灵活 N 倍。MNS 就是 “高端不锈钢抽屉柜”—— 抽屉顺滑、零件通用、还带多重锁，哪怕天天抽拉也不容易坏，而且装的东西更多、更整齐。它的核心还是 “抽屉式”：里面的开关、保护器都装在抽屉里，坏了不用断总电，抽走坏抽屉、插进好抽屉，几分钟就能恢复供电 —— 但比 GCK 做得更 “”，比如所有厂家的 MNS 抽屉都能通用，不像 GCK 可能换个就插不上。

　　1、 MNS can be understood as the 'high-end customized drawer cabinet' in low-voltage cabinets - more precise and resistant to manufacturing than GCK and GCS mentioned earlier, and N times more flexible than GGD (fixed cabinet). MNS stands for "High end Stainless Steel Drawer Cabinet" - with smooth drawers, universal parts, and multiple safety locks, it is not easy to break even if pulled every day, and it can hold more and more neatly. Its core is still the "drawer style": the switches and protectors inside are all installed in the drawer, so there is no need to cut off the main power if it is broken. Removing the damaged drawer and inserting it into the good drawer can restore power supply in a few minutes - but it is more "extreme" than GCK, for example, all manufacturers' MNS drawers can be universal, unlike GCK which may not be able to plug it in when changing brands.

　　二、MNS 的 “过人之处”：为啥要花更多钱选它？1、MNS 贵，但贵得有道理 ——?专门解决 “不能断电、要求高” 的场景，咱们拿几个例子说：医院手术室不能停电：要是控制手术设备的电柜坏了，哪怕停 1 分钟都可能出大事。MNS 的抽屉换得更快，而且有 “抗电弧” 设计（就像高压锅的防爆阀），哪怕内部出故障也不会炸，能保证电一直供着。

　　2、 MNS's' standout feature ': why spend more money choosing it? 1. MNS is expensive, but it makes sense to be so expensive -? To specifically address scenarios where power cannot be cut off and there are high requirements, let's take a few examples: the hospital operating room cannot be powered off: if the electrical cabinet controlling the surgical equipment breaks down, even if it stops for one minute, it may cause a big problem. MNS's drawers change faster and have an "arc resistant" design (similar to the explosion-proof valve of a pressure cooker), which ensures continuous power supply even if there is an internal malfunction.

　　2、数据中心服务器多：一个机房有几百台服务器，每台都要独立供电。MNS 的抽屉做得特别紧凑，一个柜子能装十几个抽屉（比 GCK 多装一半），还能实时监控每个抽屉的电流 —— 哪个服务器用电异常，马上能找到，不用挨个查。

　　2. Multiple servers in the data center: There are hundreds of servers in one data center, each of which requires independent power supply. The drawers of MNS are made particularly compact, with one cabinet able to hold more than ten drawers (half more than GCK), and can also monitor the current of each drawer in real time - any server with abnormal power consumption can be found immediately, without the need to check one by one.

　　3、机场、高铁站不能出岔子：控制安检机、显示屏、空调的电柜，要是坏了会影响旅客通行。MNS 的零件都是 “抗造款”，比如抽屉轨道用的是金属耐磨材质，用十年都不会卡，而且防尘、防潮（像给柜子加了 “防水罩”），哪怕环境有点潮也不会坏。简单说：MNS 就是 “低压柜里的‘牌’”—— 适合 “断不起电、坏不起” 的地方，花更多钱买个 “万无一失”。

　　3. Airports and high-speed railway stations must not have any mishaps: the electrical cabinets that control security screening machines, display screens, and air conditioning, if damaged, will affect passenger passage. The parts of MNS are all "anti manufacturing", for example, the drawer track is made of metal wear-resistant material, which will not get stuck after ten years of use, and is dustproof and moisture-proof (such as adding a "waterproof cover" to the cabinet), even if the environment is a little damp, it will not be damaged. Simply put, MNS is the 'safety label' in low-voltage cabinets - suitable for places where 'power cannot be cut off or broken', spend more money to buy a 'foolproof' one.

　　“高端、重要、不能断电” 的地方，基本都选 MNS

　　Most places that are high-end, important, and cannot be powered off choose MNS

　　三、平时怎么维护？

　　3、 How to maintain it normally?

　　1、虽然 MNS 高端，但维护不复杂，电工师傅稍微学一下就会：定期 “遛一遛” 抽屉：像高端抽屉柜要保养轨道一样，偶尔抽拉一下 MNS 的抽屉，看看有没有卡顿，轨道里别积灰（积灰会影响顺滑度）。

　　1. Although MNS is high-end, maintenance is not complicated. Electricians can learn it a little: regularly "take a walk" drawers: just like high-end drawer cabinets need to maintain the track, occasionally pull and pull MNS drawers to see if there is any jamming, and do not accumulate dust in the track (dust accumulation can affect smoothness).

　　2、擦一擦 “通电接头”：抽屉后面的铜片（跟柜子通电的地方），时间长了会氧化发黑，用干布擦一擦 —— 不然接触不好会发热，影响供电稳定。

　　2. Wipe the "power connector": The copper sheet behind the drawer (where it is connected to the cabinet) will oxidize and turn black over time. Use a dry cloth to wipe it - otherwise, poor contact will cause heating and affect power supply stability.

　　3、检查 “锁”：MNS 的设计比 GCK 更严，比如抽屉没推到底、柜门没关好，不仅通不了电，还会报警提醒。定期试试这些锁好不好使，别让报警功能失灵

　　3. Check the 'safety lock': The safety design of MNS is stricter than GCK, such as drawers not being pushed to the bottom, cabinet doors not being closed properly, not only cannot be powered on, but also alarm reminders. Regularly try these locks to see if they work, and don't let the alarm function malfunction

　　给个 “选柜小口诀”，记不住就看这个：没钱、简单、不怕停→GGD；中等预算、小负载、能等配件→GCK；怕停、有大负载、要通用→GCS；不能停、要、不差钱→MNS。

　　Finally, give me a "cabinet selection mnemonic". If you can't remember it, look at this: no money, simple, not afraid of stopping → GGD; Medium budget, low load, energy and other accessories → GCK; Afraid of stopping, under heavy load, requiring universal → GCS; Cannot stop, must be safe, not short of money → MNS.
