误操作，如错误地合闸、分闸。

Incorrect operation, such as closing or opening the circuit incorrectly.

插头故障 ：

Plug malfunction:

一次与二次插头故障 ：主要原因是接触不良。

Primary and secondary plug faults: The main reason is poor contact.

自动开关无法合闸 ：

The automatic switch cannot be closed:

储能弹簧未储能 ：手动合闸过程中，储能弹簧未完成储能。

Energy storage spring not stored: During the manual closing process, the energy storage spring did not complete the energy storage.

兰色按钮未复位 ：合闸前未将兰色按钮复位。

Blue button not reset: The blue button was not reset before closing.

储能电机损坏 ：储能电机老化或损坏。

Damaged energy storage motor: The energy storage motor is aging or damaged.

控制电源异常 ：储能电机无法进行储能，接触不良或控制电路失去。

Abnormal control power supply: The energy storage motor cannot store energy, poor contact or loss of control circuit.

母线故障 ：

Bus fault:

母线段进线开关故障 ：控制柜内K15故障的继电器动作，导致继电保护器投入使用。

Bus section incoming switch fault: The relay action of K15 fault in the control cabinet caused the relay protector to be put into use.

抽屉温度过高 ：负荷过高或接线松动引起。

Drawer temperature too high: caused by high load or loose wiring.

断路器故障 ：

Circuit breaker malfunction:

MT10H1型断路器故障 ：瞬时脱扣lsd系数设定值太小，长延时跳闸延时tr=4s。

MT10H1 circuit breaker fault: The instantaneous tripping LSD coefficient setting value is too small, and the long delay tripping delay tr=4s.

Emax型断路器故障 ：自动空气开关跳闸，通常由于母线负荷超过限定水平或出现相间短路。

Emax type circuit breaker fault: Automatic air switch trips, usually due to bus load exceeding the limit level or phase to phase short circuit.

其他故障 ：

Other faults:

负荷过载 ：抽屉开关下游电气设备接地或短路。

Load overload: Electrical equipment downstream of the drawer switch is grounded or short circuited.

热继电器故障 ：热继电器动作缺陷。

Thermal relay malfunction: Defects in the operation of the thermal relay.

二次回路端子脱落 ：抽屉间隔内二次回路端子脱落。

Secondary circuit terminal detachment: The secondary circuit terminal detachment occurs within the drawer compartment.

控制回路电源失去 ：220V交流电源或24V直流信号电源失去。

Control circuit power loss: Loss of 220V AC power or 24V DC signal power.
