Cleaning and maintenance

低压配电柜每隔一段时间都需要进行清洁，以确保电气元件的正常运行。在清洁时，应先切断电源，用软刷或干净的布擦拭配电柜的表面，特别是盖板、门和插座等易受灰尘和脏物积累的地方。同时，还要检查配电柜的通风孔是否被堵塞，如果有堵塞，应及时清理，以免影响散热效果。

The low-voltage distribution cabinet needs to be cleaned at regular intervals to ensure the normal operation of electrical components. When cleaning, the power should be cut off first, and the surface of the distribution cabinet should be wiped with a soft brush or clean cloth, especially in areas prone to dust and dirt accumulation such as covers, doors, and sockets. At the same time, it is also necessary to check whether the ventilation holes of the distribution cabinet are blocked. If there are blockages, they should be cleaned in a timely manner to avoid affecting the heat dissipation effect.
