Maintenance knowledge of high and low voltage complete equipment
2、一级维护
2. Primary maintenance
（1）检查母线及其下引线是否牢固。
(1) Check whether the bus and its lower lead are firm.
（2）检查二次回路接线是否牢固，熔断器是否完好以及绝缘电阻的摇测。
(2) Check whether the secondary circuit wiring is firm, whether the fuse is intact and the shake measurement of insulation resistance.
（3）电容柜的检查：断开空气开关不带电容时对电容器控制器进行动作试验，应先合的先断，后合的后断，对过压保护，欠流保护、投切门限值进行调整。
(3) Inspection of capacitor cabinet: when the air switch is disconnected and there is no capacitor, conduct action test on the capacitor controller, which should be closed first and then closed and then disconnected, and adjust the threshold values of overvoltage protection, under current protection and switching.
（4）各指示灯应完好，对断路器漏电开关，热继电器，是间及是继电器，多功能表等进行检查调整。
(4) Each indicator light shall be intact, and the circuit breaker, leakage switch, thermal relay, relay and multi-function meter shall be checked and adjusted.
（5）检查批示灯是否正常，控制器开关位置是否正常，运行应正常，手动调试机械连锁部分合闸是否可靠。
(5) Check whether the indicator light is normal, the switch position of the controller is normal, the operation should be normal, and manually debug whether the closing of the mechanical interlocking part is reliable.
（6）检查各软起动器、变频器的紧固件是否可无松动。
(6) Check whether the fasteners of each soft starter and frequency converter are loose.
3、二级维护
3. Secondary maintenance
（1）检查抽屉式开关推入或抽出是否灵活，其机械闭锁可靠，接触器触头是否良好。
(1) Check whether the drawer switch is pushed in or pulled out flexibly, its mechanical locking is reliable, and whether the contactor contact is in good condition.
（2）检查断路器内各刀口弹力是否正常，灭弧装置是否完好。
(2) Check whether the knife edge elasticity in the circuit breaker is normal and whether the arc extinguishing device is intact.
（3）检查各电缆头接线螺母是否紧固。
(3) Check whether the wiring nuts of each cable head are fastened.
（4）将受电柜和联络柜的主开关断开后，用专用摇把摇出或摇出应灵活，各互感器等二次接线头接触良好紧固无松动，一、二次线路无霉变。
(4) After disconnecting the main switch of the power receiving cabinet and the contact cabinet, shake it out or shake it out flexibly with a special crank. The secondary connectors such as each transformer are in good contact without looseness, and the primary and secondary lines are free of mildew.
4、进线开关的日常保养
4. Daily maintenance of incoming switch
（1）检查设备的清洁程度，使用清洁的干布擦掉任何灰尘和油迹，可能的情况下可使用非腐蚀性洗涤剂。
(1) Check the cleanliness of the equipment, wipe off any dust and oil stains with a clean dry cloth, and use non corrosive detergent if possible.
（2）检查设备铭牌是否完好。使用清洁干布半角这些铭牌清洁干净。
(2) Check whether the equipment nameplate is intact. Use a clean dry cloth to clean these nameplates.
（3）擦掉灰尘、霉菌和氧化物，同时也要清洁抽出式断路器的固定部分内部。确保断路器室内无异物。
(3) Wipe off dust, mold and oxides, and clean the inside of the fixed part of the withdrawable circuit breaker. Ensure that there is no foreign matter in the circuit breaker room.
（4）用清洁干的布断路器边线及母线上的灰尘或污垢。
(4) Clean the dust or dirt on the circuit breaker sideline and bus with a clean and dry cloth.
（5）确认用于端子连接的螺栓都正确地紧固，确认端子上没有局部过热的迹象。通过观察接触部分的颜色是否改变可以识别出是否发热，接触部分通常都是银白色。
(5) Confirm that the bolts used for terminal connection are tightened correctly, and confirm that there is no sign of local overheating on the terminal. Whether the contact part is hot can be identified by observing whether the color of the contact part changes. The contact part is usually silver white.
（6）检查滑动触点或端子排上的线缆是否牢固。
(6) Check whether the cable on the sliding contact or terminal block is secure.
