变压器在运行中进行滤油、加油、换硅胶或在散热器、潜油泵检修后投入前，应先将重瓦斯接信号，待空气排尽后，方可将重瓦斯投入跳闸位置。

当油位计上指示的油面有异常升高或油路系统有异常现象时，为查明原因，需要打开各个放气或放油塞子、阀门，检查吸湿器，或在进行其他工作时必须先将重瓦斯改接至信号，然后才能开展工作，以防瓦斯保护误动作跳闸。

2 瓦斯保护信号动作的主要原因

若瓦斯保护动作，变压器开关跳闸，一般情况下，其事故过程已结束，后果比较严重。因此，必须在瓦斯信号动作时，认真检查，仔细分析，正确判断，立即采取措施。变压器瓦斯继电器有浮筒式、挡板式、开口杯式等不同型号，目前大多采用QJ-80型瓦斯继电器，其信号回路接上开口杯，跳闸回路接下挡板。所谓瓦斯保护信号动作，是指因各种原因造成继电器内上开口杯的信号回路接点闭合，轻瓦斯动作。接点闭合的原因一般有以下几方面。
