| 现场值守电工若发现分合闸指示灯不亮，应及时检查分合闸回路是否断线；检修人员在停电检修时应注意测量分闸线圈的电阻，检查分闸顶杆是否变形；如果分闸顶杆的材质为铜质应更换为钢质；必须进行低电压分合闸试验，以保证断路器性能可靠。 If an electrician is found to be in a broken light, check the broken line in the closing circuit. The maintenance personnel should be careful to measure the resistance of the brake coils during power outages, and check whether the roof rods are deformed. If the material of the split top bar is replaced by steel; Low voltage dielectric lock test must be carried out to ensure reliable performance of circuit breaker. |
