| 低压开关设备的运行监护 Operation monitoring of low voltage switch equipment （1） 在用的电源开关柜，值班电工应至少每隔2小时巡查一次，检查线电压，相电压的 (1) in the use of the power switch cabinet, the duty electrician shall patrol at least once every two hours, check the line voltage and phase voltage 平衡情况和电流的变化情况（相间电压的不平衡不得查过±5%，任何一相电流与三相平均值不应大于平均值的10%），若有异常，应及时报告有关人员并采取相应措施； Balance condition and the change of current (alternating voltage imbalance will not be checked in plus or minus 5%, any should not be greater than 10% of the average current and the three-phase average), if there is abnormal, should timely report the relevant personnel and take corresponding measures; （2） 巡查开关设备有无异常声响、异味，如爆鸣、焦臭等现象； (2) there is no abnormal sound or odor in the examination and switching equipment, such as detonation, coke and other phenomena; （3） 巡查各种指示仪表、信号装置运行是否正常； (3) to inspect all kinds of indicators and signal devices to operate properly; （4） 开关设备的正常检查和检修 (4) normal inspection and repair of switching equipment 1） 检查断路器、接触器的触头，修磨或更换烧损严重的触头； 1) check the contact head of the circuit breaker and the contactor, make a grinding or replace the badly burned contact. 2） 检查开关柜的二次回路的接线是否牢固，继电保护装置运行是否正常，是否掉牌； 2) check whether the connection of the secondary circuit of the switch cabinet is strong, and the relay protection device is running properly. 3） 检查操作机构的辅助开关接触是否可靠； 3) to check whether or not the auxiliary switch of the operator is reliable; 4） 检查分、合闸线圈有无发黑和发焦，电缆头、电缆有无发热； 5） 检查接地地线是否有腐蚀、折断、接触是否良好； 6） 检查开关的操作机构分、合闸是否灵活。 4) inspection of the points and closing coils shall be black and coke, and the cable head and cable shall not be hot. 5) check for corrosion, breaking, and good contact of ground floor. 6) check the operating mechanism of the switch and be flexible. |
