低壓抽屜柜常見的故障以及處理方法

Common faults and solutions of low-voltage drawer cabinets

　　欠壓線圈不工作。檢查并更換欠壓線圈。

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

　　合閘按鈕接觸不良。更換合閘按鈕。

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

　　控制回路熔芯燒壞。確認控制回路正常無短路后，更換熔芯。

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.

　　斷路器未儲能。檢查電動機控制電源電壓，需≥85%。

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

　　合閘電磁鐵控制電源電壓小于85%。調整合閘電磁鐵供電電壓≥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%.

　　合閘電磁鐵損壞。更換合閘電磁鐵。

The closing electromagnet is damaged. Replace the closing solenoid.

　　抽屜式斷路器二次回路接觸不良。將抽屜式斷路器搖出后重新接通正確位置，檢查二次回路連接是否可靠。

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.

　　漏電故障。斷電后檢查接線端子緊固情況，使用萬用表檢查接線端子之間是否有連接，如有損壞或老化則更換相關部件。

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。斷電后確認短路處并進行絕緣處理，如為設備內部短路，則更換相關部件或對設備進行維修。

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.

　　過載故障。斷電后檢查負載大小是否超過設備承載能力，減輕負載或更換更適合的設備檔位。

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.

　　以上方法適用于處理低壓抽屜柜常見的各種故障，但在實際操作時，應根據具體情況選擇合適的方法，并遵循操作規程。。

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..
