| 成套电气类保养知识 Complete electrical maintenance knowledge 一、低压配电柜 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。 Regularly check for signs of insect activity in the cabinets and make regular traps. 2．检查各警告牌、检修牌摆放位置是否正确。 Check all warning signs and check CARDS for correct placement. 3．检查应急工具、灯具是否齐全、正常，摇把及熔断器手柄是否齐全。 Check to see if the emergency tools, lamps and lanterns are complete and normal, and the handle of the fuse and fuse is 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）。 Check for any hot or hot discoloration (usually silver) and no corrosion (normal welding points). 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。 Check that the capacitor shell in the capacitor cabinet is good, whether it is leaking or expanding, and the indicator lamp is good. 6．检查各电容器外壳接地线接触情况。 Check the ground connection of the capacitor shell. 7．做好各柜休的保洁除尘工作。 Do the cleaning and dusting work. 8．检查各柜体的风扇工作情况。 Check the fan work of the cabinets. 二、一级维护 Second, maintenance 1．检查母线及其下引线是否牢固。 Check the strength of the bus line and its lower leads. 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。 Check whether the secondary circuit is strong, the fuse is in good condition and the insulation resistance is shaken. 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. The capacitance ark inspection: disconnect air switch with no capacitance of capacitor controller action test, should be first of first break, after close after the break, the over voltage protection, low flow protection, to adjust the cutting threshold method. 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。 All indicator lamps should be in good condition, the circuit breaker leakage switch, heat relay, and the relay, multi-function watch, 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。 Check to check whether the lights are normal, the position of the controller is normal, the operation should be normal, and manually adjust the mechanical chain part lock to be reliable. 6．检查各软起动器、变频器的紧固件是否可无松动。 Check whether the firmware of each soft starter and frequency converter is not loose. |
