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

儲能電機損壞 ：儲能電機老化或損壞。

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

控制電源異常 ：儲能電機無法進行儲能，接觸不良或控制電路失去。

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

母線故障 ：

Bus fault:

母線段進線開關故障 ：控制柜內K15故障的繼電器動作，導致繼電保護器投入使用。

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

抽屜溫度過高 ：負荷過高或接線松動引起。

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

斷路器故障 ：

Circuit breaker malfunction:

MT10H1型斷路器故障 ：瞬時脫扣lsd系數設定值太小，長延時跳閘延時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型斷路器故障 ：自動空氣開關跳閘，通常由于母線負荷超過限定水平或出現相間短路。

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:

負荷過載 ：抽屜開關下游電氣設備接地或短路。

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

熱繼電器故障 ：熱繼電器動作缺陷。

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

二次回路端子脫落 ：抽屜間隔內二次回路端子脫落。

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