低压配电箱具有分断能力强，动热稳定性好，电气方案引灵活，组合方便，系列性、实用性强，结构新颖等特点。对于低压配电箱的养护，每半年一次。

The low voltage distribution box has the characteristics of strong breaking capacity, good dynamic and thermal stability, flexible electric scheme, convenient combination, seriation, practicability and novel structure. The maintenance of the low voltage distribution box is once every half a year.

养护的顺序是先做好养护前的准备，而后分段施行配电箱的养护。当配电箱较多时，一般采用双列方式排列，两列之间由柜顶的母线隔离开关相连。为缩减停电范围，对配电柜进行分段养护。先停掉一段母线上的全部负荷，打开母线隔离开关。检查确认无电后，挂上接地线和标示牌即可开始养护。检查配电箱中各种开关，取下灭弧罩，看触头是否有损坏。紧固进出线的螺栓，清洁柜内尘土，试验操动机构的分合闸情况。检查母线接头有无变形，有无放电的痕迹，紧固连接螺栓确保连接紧密。母线接头处有脏物时应清除，螺母有锈蚀现象应更换。

The order of maintenance is to prepare for the maintenance before maintenance, and then the maintenance of the distribution box. When the distribution box is more, it is usually arranged in a double row mode, and the two columns are connected by the busbar isolation switch at the top of the cabinet. In order to reduce the range of power outage, the distribution cabinet is maintained in subsection. Stop all the load on a busbar first and open the bus isolation switch. After checking and confirming no electricity, hang the grounding wire and sign board to start the maintenance. Check all kinds of switches in the distribution box and take off the cover to see if the contact is damaged. Fasten the bolts in and out of the line, the dust in the cleaning cabinet, and test the closing of the operating mechanism. Check the busbar joint has no deformation, there is no discharge trace, fastening the connection bolt to ensure that the connection is tight. The busbar joint should be removed when there is dirt, and the nut rust should be replaced.
