MNS低壓抽屜柜通常指將電氣元件和部件組合成配電系統，安裝在箱或柜內。看起來很美，操作起來也很方便，那么平時都是怎么保養的呢？

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?

要做好防塵工作，這需要一個長期的、經常性的工作。大家可能都知道，MNS低壓抽屜柜大部分都是金屬材質的，所以要做好防銹防腐工作，同時要降低地面的濕度。此外，可以使用刷子定期清潔，以灰塵對絕緣性能的影響。

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.

比如日常生活中經常使用的斷路器，要定期檢查是否有螺絲松動，及時進行加固工作。同時，在很多情況下，由于生產需要，臨時電源可能從開關柜上接出。此時應嚴格按照電氣管理規定使用絕緣性能好的電線，并要求技術人員操作。

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.

檢查抽屜式開關時，抽屜式開關柜在推入或拉出時應靈活，機械閉鎖可靠。檢查抽屜柜上的自動空氣開關操作機構是否到位，接線螺絲是否緊固。接觸器觸頭表面及四周的污物，檢查接觸器觸頭接觸是否完好，如觸頭接觸不良，必要時可稍微修銼觸頭表面，如觸頭嚴重燒蝕（觸頭點磨損原厚度的1/3）即應更換觸頭。電源指示儀表、指示燈完好。

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低壓抽屜柜一般檢查：主要檢查外觀清潔和對母線的外觀檢查、運行測試，建議每年一次。對安裝板上功能單元的檢查和維護：主要檢查連線是否正常，建議五年一次。

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.
