MNS低压抽屉柜通常指将电气元件和部件组合成配电系统，安装在箱或柜内。看起来很美，操作起来也很方便，那么平时都是怎么保养的呢？

MNS low-voltage drawer cabinet usually refers to the combination of electrical elements and components into a power distribution system, which is installed in a box or cabinet. It looks beautiful and easy to operate. How do you maintain it?

要做好防尘工作，这需要一个长期的、经常性的工作。大家可能都知道，MNS低压抽屉柜大部分都是金属材质的，所以要做好防锈防腐工作，同时要降低地面的湿度。此外，可以使用刷子定期清洁，以消除灰尘对绝缘性能的影响。

To do a good job in dust prevention, it needs a long-term and regular work. As you may know, most of the MNS low-voltage drawer cabinets are made of metal, so it is necessary to do a good job in rust prevention and corrosion prevention, and at the same time to reduce the humidity of the ground. In addition, brush can be used for regular cleaning to eliminate the impact of dust on insulation performance.

比如日常生活中经常使用的断路器，要定期检查是否有螺丝松动，及时进行加固工作。同时，在很多情况下，由于生产需要，临时电源可能从开关柜上接出。此时应严格按照电气管理规定使用绝缘性能好的电线，并要求技术人员操作。

For example, for the circuit breaker that is often used in daily life, it is necessary to regularly check whether there are screws loose and carry out reinforcement work in time. At the same time, in many cases, due to production needs, the temporary power supply may be connected from the switch cabinet. At this time, wires with good insulation performance shall be used in strict accordance with the electrical management regulations, and technicians shall be required to operate.

检查抽屉式开关时，抽屉式开关柜在推入或拉出时应灵活，机械闭锁可靠。检查抽屉柜上的自动空气开关操作机构是否到位，接线螺丝是否紧固。清除接触器触头表面及四周的污物，检查接触器触头接触是否完好，如触头接触不良，必要时可稍微修锉触头表面，如触头严重烧蚀（触头点磨损至原厚度的1/3）即应更换触头。电源指示仪表、指示灯完好。

When checking the drawer switch, the drawer switch cabinet shall be flexible when pushing in or pulling out, and the mechanical locking shall be reliable. Check whether the automatic air switch operating mechanism on the drawer cabinet is in place and whether the wiring screws are tight. Clean the dirt on and around the contact surface of the contactor and check whether the contact is in good condition. If the contact is in poor contact, slightly file the contact surface if necessary. If the contact is severely burnt (the contact point is worn to 1/3 of the original thickness), replace the contact. The power indicator and indicator are in good condition.

MNS低压抽屉柜一般检查：主要检查外观清洁和对母线的外观检查、运行测试，建议每年一次。对安装板上功能单元的检查和维护：主要检查连线是否正常，建议五年一次。

General inspection of MNS low-voltage drawer cabinet: mainly inspect the appearance and cleanliness, and the appearance inspection and operation test of the bus. It is recommended to conduct the inspection once a year. Inspection and maintenance of functional units on the installation board: mainly check whether the wiring is normal, and it is recommended to check once every five years.
