Although the low-voltage drawer cabinet is not a high-risk equipment, but daily inspection is essential, and individual period of fault inspection and regular inspection need to be paid attention to. So what problems should we pay attention to when checking the low-voltage drawer cabinet? The inspection of MNS low-voltage drawer cabinet needs to pay attention to many problems. In the process of daily inspection and troubleshooting, it is not only necessary to remove the fault and replace the accessories, but also try to do all-round inspection every time.

低压抽屉柜日常检查的工作项目包括：

Daily inspection items of low voltage drawer cabinet include:

1·配电柜及柜中的电器元件的名称、标志、编号等是否清楚、正确，盘上所有的操作把手、按钮和按键等的位置与现场情况是否相符，固定是否牢靠。

1. Whether the name, mark and number of the power distribution cabinet and the electrical components in the cabinet are clear and correct, whether the positions of all the operation handles, buttons and keys on the panel are consistent with the site conditions, and whether the fixation is firm.

2·配电柜上表示“合”、“分”的信号灯及其它信号指示是否正确。

2. Whether the signal lights and other signals indicating "on" and "off" on the power distribution cabinet are correct.

3·隔离开关、断路器、熔断器和互感器等的触点是否牢靠，有无过热变色现象。

3. Whether the contacts of disconnector, circuit breaker, fuse and mutual inductor are reliable, and whether there is overheating and discoloration.

4·模拟板与现场电气设备的运行状态是否对应。

4. Whether the operation status of the simulation board is corresponding to that of the field electrical equipment.

5·仪表或表盘玻璃是否松动，仪表指示是否正确。

5. Whether the instrument or dial glass is loose and whether the instrument indication is correct.

6·配电室内的照明灯具是否完好，照度是否合适。

6. Whether the lighting in the distribution room is in good condition and the illumination is appropriate.

7·认真记录巡视检查中发现的问题，以及现场处理情况。

7. Carefully record the problems found in the inspection and the on-site treatment.

检查MNS低压抽屉柜要注意以下问题：

Pay attention to the following problems when checking MNS low-voltage drawer cabinet:

1·外观查看：检查是否有移位、掉漆、腐蚀、生锈、变形、变色、异味等情况。这些都可能是某些部件发生故障但是尚未影响到电力输送的情况，但是隐患已经存在了。移位或者柜体倾斜等都不利于低压抽屉柜的使用，要及时矫正；掉漆、变形：可能是机械性外力导致的，是否有弹簧跳出；腐蚀、生锈、变色是否有化学药剂或者污水腐蚀或者电弧、火苗导致的；异味：大多是由于高温、着火等原因导致的，这些基本的问题都一定要排查。

1. Appearance inspection: check whether there is displacement, paint dropping, corrosion, rust, deformation, discoloration, peculiar smell, etc. These may be some parts of the failure, but has not yet affected the power transmission, but the security risks already exist. Displacement or cabinet tilt are not conducive to the safe use of low-pressure drawer cabinet, to be corrected in time; paint, deformation: may be caused by mechanical external force, whether there is spring jump; corrosion, rust, discoloration is caused by chemical agents or sewage corrosion or arc, flame; odor: mostly due to high temperature, fire and other reasons, these basic problems are not obvious We must check.

2·温度检查：温度是检验电力系统故障的常用方法，大多数电路故障都是短路、过压、过载等原因导致的问题，因此温度检查非常重要。

2. Temperature inspection: temperature is a common method to inspect power system faults. Most circuit faults are caused by short circuit, overvoltage, overload and other reasons, so temperature inspection is very important.

3·杂物检查：在对低压抽屉柜更换配件过程中是否有破损配件的残余躯体，在元器件安装过程中会残留大量的线头、零件以及铁屑等，其中部分会附着在元器件的表面或里层，因此清扫工作一定要仔细、认真，确保细节干净。

3. Debris inspection: whether there are residual bodies of damaged accessories in the process of replacing accessories for low-voltage drawer cabinet, and a large number of thread ends, parts and scrap iron will be left in the process of component installation, some of which will be attached to the surface or inner layer of components, so the cleaning work must be careful and careful to ensure that the details are clean.

4·机械检查：断路器、低压抽屉进出操作灵活，无卡滞现象。如果有，检查原因，适当修复。

4. Mechanical inspection: the circuit breaker and low-voltage drawer can be operated flexibly without jamming. If so, check the cause and repair properly.
          

5·检查润滑油：高压断路器、低压抽屉等动触头，有适量中性润滑油脂，查看是否有跑冒滴漏等现象。

5. Check the lubricating oil: high voltage circuit breaker, low voltage drawer and other moving contacts, there is an appropriate amount of neutral lubricating grease, check whether there is leakage and other phenomena.

6·系统参数查验：抽屉柜柜内母线制作、安装检查，母线相序正确，是否严格按照图纸规划及配电连接标准安装执行进行安装操作。这一般在初次安装后进行检查，后期不用每次巡检，在每次更换配件合闸供电之前还需要对更换的配件进行一次电路系统的安装检查。

6. System parameter inspection: check the production and installation of the busbar in the drawer cabinet, check whether the busbar phase sequence is correct, and whether the installation operation is carried out in strict accordance with the drawing planning and safe power distribution connection standard. Generally, the inspection is carried out after the initial installation, and there is no need to inspect every time in the later stage. Before switching on the power supply, the replacement accessories need to be inspected once for the installation of the circuit system.

在MNS低压抽屉柜使用过程中，一般的日常巡检就是这么多的工作，但这是建立在初次合格安装的基础上，如果是初次安装需要检查的东西就太多了。

In the use process of MNS low-voltage drawer cabinet, the general daily inspection is so much work, but it is based on the first safe and qualified installation. If it is the first installation, there are too many things to check.
