Flammable gas found in the relay indicates some internal fault such as overheating or arcing, whereas air found in the relay may only indicate low oil level or a leak.

如果在继电器中发现可燃气体，这说明有内部故障，比如过热或者电弧作用；而继电器内的空气只说明油位低或者有漏油。

On a slow accumulation of gas, due perhaps to slight overload, gas produced by decomposition of insulating oil accumulates in the top of the relay and forces the oil level down.

在气体慢积累模式中，可能由于轻微过在，绝缘油分解产生的气体在继电器的顶部聚集，迫使油位下降。
