In order to ensure the normal power supply to the electric field, the instruments and electrical appliances on the distribution panel shall be regularly inspected and maintained, and records shall be made, so as to analyze the operation and power consumption at any time, find problems and eliminate hidden dangers in time.

对运行中的低压开关柜，通常应检查以下内容：

For the low-voltage switchgear in operation, the following contents shall be checked:

(1)配电屏及屏上的电气元件的名称、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实际情况是否相符，固定是否牢靠，操作是否灵活。

(1) Whether the name, mark and number of the distribution panel and the electrical components on the panel are clear and correct, whether the positions of all operation handles, buttons and keys on the panel are consistent with the actual situation on site, whether the fixation is firm and whether the operation is flexible.

(2)配电屏上表示“合”、“分”等信号灯和其他信号指示是否正确。

(2) Whether the "on", "off" and other signal indicators and other signal indications on the distribution panel 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) Check whether the contacts of disconnectors, circuit breakers, fuses and mutual inductors are reliable and whether there is overheating and discoloration.

(4)二次回路导线的绝缘是否破损、老化。

(4) Whether the insulation of secondary circuit conductor is damaged and aged.

(5)配电屏上标有操作模拟板时，模拟板与现场电气设备的运行状态是否对应。

(5) When the operation simulation board is marked on the distribution panel, whether the operation status of the simulation board corresponds to that of the on-site electrical equipment.

(6)仪表或表盘玻璃是否松动，仪表指示是否正确。

(6) Whether the instrument or dial glass is loose and whether the instrument indication is correct.

(7)配电室内的照明灯具是否完好，照度是否明亮均匀，观察仪表时有无眩光。

(7) Whether the lighting fixtures in the distribution room are in good condition, whether the illumination is bright and uniform, and whether there is glare when observing the instrument.

(8)巡视检查中发现的问题应及时处理，并记录。

(8) Problems found during patrol inspection shall be handled in time and recorded.

低压带电工作安全要求

Safety requirements for low voltage live working

低压带电工作应设专人监护，使用有绝缘柄的工具，工作时站在干燥的绝缘物上，戴绝缘手套和安全帽，穿长袖衣，严禁使用锉刀、金属尺和带有金属物的毛刷、毛掸等工具。

For low-voltage live work, special personnel shall be assigned to monitor and use tools with insulating handle. When working, stand on dry insulation, wear insulating gloves, safety helmets and long sleeved clothes. It is strictly prohibited to use files, metal rulers, brushes and Dusters with metal objects.

在高低压同杆架设的低压带电线路上工作时，应先检查与高压线的距离，采取防止误碰高压带电设备的措施。

When working on the low-voltage live line erected on the same pole of high and low voltage, first check the distance from the high-voltage line and take measures to prevent accidental collision with the high-voltage live equipment.
