山东MNS低压抽屉柜

　　Shandong MNS Low Voltage Drawer Cabinet

　　山东MNS低压抽屉柜是采用钢板制成封闭外壳，进出线回路的电器元件都安装在可抽出的抽屉中，构成能完成某一类供电任务的功能单元。功能单元与母线或电缆之间，用接地的金属板或塑料制成的功能板隔开，形成母线、功能单元和电缆三个区域。每个功能单元之间也有隔离措施。抽屉式开关柜有较高的可靠性、性和互换性，是比较的开关柜，目前生产的开关柜，多数是抽屉式开关柜。它们适用于要求供电可靠性较高的工矿企业、高层建筑，作为集中控制的配电中心。

　　The Shandong MNS low-voltage drawer cabinet is made of steel plate with a closed shell, and the electrical components of the incoming and outgoing circuit are installed in the withdrawable drawer, forming a functional unit that can complete a certain type of power supply task. The functional unit is separated from the busbar or cable by a grounded metal plate or plastic functional board, forming three areas: busbar, functional unit, and cable. There are also isolation measures between each functional unit. Drawer type switchgear has high reliability, safety, and interchangeability, and is a relatively advanced switchgear. Currently, most of the produced switchgear are drawer type switchgear. They are suitable for industrial and mining enterprises and high-rise buildings that require high power supply reliability, serving as centralized control distribution centers.

　　低压柜抽屉的使用

　　The use of drawers in low-voltage cabinets

　　一、拔出推进时操作应注意的事项:1/4抽屉与1/2抽屉(黑色的):当把抽屉向里面推进时，在抽屉推进前，先把抽屉放平，在滑轨上来回推动几下，确认已落槽，再推进。(若没落槽，就推进后，该抽屉将很难再拉出来，因抽屉两边的镶嵌的隔板卡住柜体框架而拔不出来，会毁坏抽屉两边的隔板和一次插件)

　　1、 Precautions for pulling out and pushing: 1/4 drawer and 1/2 drawer (black): When pushing the drawer inward, before pushing it, first flatten the drawer, push it back and forth on the slide rail a few times, confirm that it has fallen into the slot, and then push it forward. (If it doesn't fall into the slot, it will be difficult to pull out the drawer again after pushing it in, because the embedded partitions on both sides of the drawer are stuck in the cabinet frame and cannot be pulled out, which will damage the partitions and primary plugs on both sides of the drawer)

　　处理方法:

　　Processing method:

　　1、将上下两抽屉拔出，用长螺丝刀通过缝隙压迫镶嵌板的卡住点，再拔出，如果硬拉出，将不可避免导致抽屉框架的损坏。

　　1. Pull out the upper and lower drawers, use a long screwdriver to press the locking point of the embedded panel through the gap, and then pull out. If you forcefully pull out, it will inevitably cause damage to the drawer frame.

　　因开机或正常运行时，上下两抽屉难免都在运行，可能不允许拔出抽屉，故处理比较麻烦，所以送电时要注意该方法的运用，做到心急而手不急，按正常顺序操作，减少故障时间，避免影响生产

　　Due to the fact that both the upper and lower drawers are inevitably running during startup or normal operation, it may not be possible to remove the drawers, making it difficult to handle. Therefore, when powering on, attention should be paid to the use of this method, ensuring that the heart is in a hurry but the hands are not in a hurry, and operating in the normal order to reduce downtime and avoid affecting production

　　2、在抽屉推进时，距合上位置15CM左右时，用23磅的力推进即可。切忌抽屉的全行程猛推，这样极易损坏抽屉;如用力太小，又不易推进到位。

　　2. When pushing the drawer forward, apply a force of 2 to 3 pounds when it is about 15CM away from the closed position. Never forcefully push the drawer throughout its full range, as this can easily damage the drawer; If the force is too small and difficult to push into place.

　　3、在抽屉推进后的操作顺序:旋转旋钮(黑色)到试验位置按绿色启动按钮启动(如接触器吸合，运行指示灯亮，说明完好)然后按住旋钮(垂直旋钮轴心微用力直接旋转到运行位置，旋钮的红线是垂直方向);

　　3. The operation sequence after pushing the drawer: Rotate the knob (black) to the test position and press the green start button to start (if the contactor is closed, the running indicator light is on, indicating that it is intact), then press and hold the knob (rotate the vertical knob axis slightly to the running position, and the red line of the knob is in the vertical direction);

　　如果不用力按住旋钮，将会撑坏按钮，导致无法送电;打旋钮送电时，有时会出现难以旋动，此时要检查抽屉是否旋转到位。外观看，抽屉框架与柜体框架是否合缝，即使有小小的12MM的距离都不行。

　　If the knob is not pressed firmly, it will break the button and prevent power transmission; When turning the knob to power on, sometimes it may be difficult to rotate. At this time, it is necessary to check whether the drawer is rotating properly. From an external perspective, whether the drawer frame and cabinet frame are seamless, even if there is a small distance of 1 to 2MM, is not acceptable.

　　二、大抽屉

　　2、 Large drawer

　　1、上述2，3也是其注意点。

　　1. The above 2 and 3 are also important points to note.

　　2、在推进时，也要试拉几下，这是因抽屉后面的二次插头和一次主插头与框架母体插接不对，(这在抽屉因故障更换时要注意，这是因为这些抽屉后面的插接头布置的类型有不同)。

　　2. When advancing, it is also necessary to try pulling a few times, as the secondary plug and primary plug behind the drawer are not properly connected to the frame body (this should be noted when replacing the drawer due to a malfunction, as the types of connectors arranged behind these drawers are different).

　　3、有时在往外拔出抽屉时，拔不出来，应稍稍向上用力提一下，再往外拉出(当然是同时进行的)，如在框架上端的抽屉，就因为往往忽略了这一点，而难以拔出。

　　3. Sometimes when pulling out a drawer, if it cannot be pulled out, it should be lifted slightly upwards and then pulled out again (of course, at the same time). For example, the drawer at the top of the frame is often overlooked and difficult to pull out.

　　4、对于二次旋钮的操作与1/4抽屉与1/2抽屉3的操作方式一样。要记住的是只有当二次旋钮达到运行位置时，才能把一次开关的旋钮推到运行位置，否则会损坏一次开关的旋钮而送不上电。

　　4. The operation of the secondary knob is the same as that of 1/4 drawer and 1/2 drawer 3. It should be remembered that the primary switch knob can only be pushed to the running position when the secondary knob reaches the running position, otherwise it will damage the primary switch knob and fail to power on.

　　5、抽屉打不开来，主要是旋纽旋不过来的问题。

　　5. The drawer cannot be opened, mainly due to the problem of the knob not rotating properly.

　　这是个主要的问题，假设坏的情况下:此时的抽屉往往是合闸状态，且又处于故障下，而生产又急于要求恢复送电开启。(1)、认识上，对于旋纽的指示位置不要过于迷信，因为它毕竟只是个机械连锁，可通过不断旋转两个旋纽位置(远控、就地旋纽;和主开关旋纽)，其位置可以试着稍稍偏离一点，再试行打开，一般打开都没有问题。

　　This is the most important issue, assuming the worst-case scenario: the drawer is often closed and in a faulty state, and production is eager to restore power supply and open it. (1) In terms of understanding, do not be too superstitious about the indication position of the knob, because it is only a mechanical chain after all. By continuously rotating two knob positions (remote control, local knob; and main switch knob), the position can be slightly deviated and then opened, and generally there is no problem with opening.

　　(2)、若遇到确实打不开的抽屉，而生产又催得比较急的情况。

　　(2) If encountering a drawer that cannot be opened and the production is urgent.

　　其快速复位送电的操作步骤:

　　The operation steps for quick reset and power transmission are as follows:

　　a:在远程、就地旋纽旁边的有一小孔(右下方)，用小螺丝刀伸进小孔向下压挡板。

　　a: There is a small hole (bottom right) next to the remote and local knob. Use a small screwdriver to insert into the hole and press down on the baffle.

　　b:在一次关左侧有一小孔，同样用另一小螺丝刀伸进去顶开。

　　b: There is a small hole on the left side that needs to be closed once, and another small screwdriver should be inserted to open it.

　　c:两螺丝刀同时用力解锁，打开抽屉门。

　　c: Use two screwdrivers to simultaneously unlock and open the drawer door.

　　d:手动调整一次开关前面连杆(有时往往打不开，就是因为该处连杆卡住)断开主开关。

　　d: Manually adjust the front link of the switch once (sometimes it cannot be opened because the link is stuck) to disconnect the main switch.

　　e:再确认主开关下方的机械连杆是否已释放到位，若没到位，活动一下即可。

　　e: Confirm again whether the mechanical linkage below the main switch has been released into place. If not, move it briefly.

　　f:旋开二次开关按钮，抽出位置

　　f: Turn on the secondary switch button to the safe extraction position

　　9:抽出抽屉，然后复位，恢复送电。

　　9: Pull out the drawer, reset it, and restore power supply.

　　h:只有一次开关与二次开关啮合到位抽屉才能抽拉自如、开关才能旋转流畅。

　　h: Only when the primary switch and the secondary switch are engaged properly can the drawer be easily pulled and the switch rotate smoothly.

　　说明:上述步骤基本上都能马上解决，当然不排除在+过程会出现一点意外情况，此时要好好确认一下e步骤是否确已释放到位，然后再取下黑色的旋纽面板，检查齿轮和齿条有无松落或硬卡住，调整一下即可，如果都是好的，才有可能确认是润滑不好，此时可用板手，用两三磅的力试旋开，切不可用力过猛。所以，只要稍加注意，柜子抽屉卡死的问题都能解决的，解决的过程是决不可以用硬砸，硬撬的。

　　Explanation: The above steps can basically be solved immediately. Of course, there may be some unexpected situations during the+process. At this time, it is necessary to carefully confirm whether step e has been released in place, and then remove the black knob panel to check whether the gear and rack are loose or hard stuck. Adjust them. If they are all good, it is possible to confirm that the lubrication is not good. At this time, a wrench can be used to try to unscrew with two to three pounds of force, and do not use too much force. So, as long as you pay a little attention, the problem of cabinet drawers getting stuck can be solved, and the process of solving it cannot be done by forcefully smashing or prying.
