一、低压配电柜
1、 Low voltage distribution cabinet
1.定期检查各柜内是否有虫鼠活动的痕迹,定期进行诱杀。
1. Regularly check whether there are traces of insect and rat activities in each cabinet, and trap and kill them regularly.
2.检查各警告牌、检修牌摆放位置是否正确。

3. Check whether the emergency tools and lamps are complete and normal, and whether the crank and fuse handle are complete.
4.检查电缆接头有无发热变色(一般都为银色),接地线有无锈蚀(焊接点是否正常)。
4. Check whether the cable joint is hot and discolored (generally silver), and whether the grounding wire is rusted (whether the welding point is normal).
5.检查电容柜内的电容器外壳是否良好,有无渗漏、膨胀情况,指示灯是否良好。
5. Check whether the capacitor shell in the capacitor cabinet is in good condition, whether there is leakage and expansion, and whether the indicator light is in good condition.
6.检查各电容器外壳接地线接触情况。
6. Check the grounding wire contact condition of each capacitor shell.
7.做好各柜休的保洁除尘工作。
7. Do a good job in cleaning and dedusting of all cabinets.
8.检查各柜体的风扇工作情况。
8. Check the fan working condition of each cabinet.
二、一级维护
2、 First level maintenance
1.检查母线及其下引线是否牢固。
1. Check whether the bus and its down lead are firm.
电气成套
2.检查二次回路接线是否牢固,贵州高低压配电设备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 of Guizhou high and low voltage power distribution equipment is in good condition, and the shake test 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 without capacitor, the action test of capacitor controller shall be carried out. The first closing shall be conducted first, and the second closing shall be conducted later. The overvoltage protection, under current protection and switching threshold value shall be adjusted.
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. All indicator lights should be in good condition. Check and adjust the circuit breaker, leakage switch, thermal relay, relay, multi-function meter, etc.
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, whether the switch position of the controller is normal, whether the operation is normal, and whether the mechanical interlock part of manual debugging 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.
三、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, whether 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 elastic force of each knife edge in the circuit breaker is normal and whether the arc extinguishing device is in good condition.
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 tight.
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 the main switch of the receiving cabinet and the contact cabinet is disconnected, it should be flexible to use the special handle to shake out or shake out. The secondary terminals such as the mutual inductor should be in good contact and tight without looseness, and the primary and secondary lines should be free from mildew.
四、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 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 name plate is in good condition. 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 the dust, mold and oxide, and clean the fixed part of the draw out circuit breaker at the same time. Make sure there is no foreign matter in the circuit breaker room.
4.用清洁干的布清除断路器边线及母线上的灰尘或污垢。
4. Use a clean and dry cloth to remove the dust or dirt on the side line and bus of the circuit breaker.
5.确认用于端子连接的螺栓都正确地紧固贵州高低压配电设备,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 correctly fastened to the high and low voltage distribution equipment in Guizhou, and confirm that there is no sign of local overheating on the terminals. By observing whether the color of the contact part changes, we can identify whether it is hot. The contact part is usually silver white.
7.检查滑动触点或端子排上的线缆是否牢固
