低压抽屉柜常见的故障以及处理方法

Common faults and solutions of low-voltage drawer cabinets

　　欠压线圈不工作。检查并更换欠压线圈。

Undervoltage coil not working. Check and replace the undervoltage coil.

　　合闸按钮接触不良。更换合闸按钮。

Poor contact of the closing button. Replace the closing button.

　　控制回路熔芯烧坏。确认控制回路正常无短路后，更换熔芯。

The control circuit fuse core is burnt out. After confirming that the control circuit is normal and there is no short circuit, replace the fuse core.

　　断路器未储能。检查电动机控制电源电压，需≥85%。

The circuit breaker is not storing energy. Check the voltage of the motor control power supply, which should be ≥ 85%.

　　合闸电磁铁控制电源电压小于85%。调整合闸电磁铁供电电压≥85%。

The closing electromagnet controls the power supply voltage to be less than 85%. Adjust the power supply voltage of the closing solenoid to ≥ 85%.

　　合闸电磁铁损坏。更换合闸电磁铁。

The closing electromagnet is damaged. Replace the closing solenoid.

　　抽屉式断路器二次回路接触不良。将抽屉式断路器摇出后重新接通正确位置，检查二次回路连接是否可靠。

Poor contact in the secondary circuit of the drawer type circuit breaker. Shake out the drawer type circuit breaker and reconnect it in the correct position to check if the secondary circuit connection is reliable.

　　漏电故障。断电后检查接线端子紧固情况，使用万用表检查接线端子之间是否有连接，如有损坏或老化则更换相关部件。

Leakage fault. After power-off, check the tightness of the wiring terminals and use a multimeter to check if there is any connection between the wiring terminals. If there is any damage or aging, replace the relevant components.

　　短路故障。断电后确认短路处并进行绝缘处理，如为设备内部短路，则更换相关部件或对设备进行维修。

Short circuit fault. After power-off, confirm the short circuit and perform insulation treatment. If it is an internal short circuit of the equipment, replace the relevant components or repair the equipment.

　　过载故障。断电后检查负载大小是否超过设备承载能力，减轻负载或更换更适合的设备档位。

Overload fault. After power outage, check if the load size exceeds the device's carrying capacity, reduce the load, or replace the device with a more suitable gear.

　　以上方法适用于处理低压抽屉柜常见的各种故障，但在实际操作时，应根据具体情况选择合适的方法，并遵循操作规程。。

The above methods are applicable to dealing with various common faults in low-voltage drawer cabinets, but in actual operation, appropriate methods should be selected according to the specific situation and safety operating procedures should be followed..
