QJ4-25 gas relay is a main protection device for internal faults in oil-immersed transformers and oil-immersed on-load tap changers. The gas relay is installed on the connecting pipeline between the transformer and the oil storage tank. When an internal fault occurs in the transformer, causing oil to decompose and produce gas or causing oil flow surge, the contact of the gas relay is activated to connect to the designated control circuit, and timely send an alarm signal or automatically cut off the transformer.

The installation position of the relay should be convenient for air extraction and observation, as well as for on-site maintenance of the relay. The installation position should ensure that the relay core can be smoothly removed from the shell:
▲ QJ4-25 type with a removal height of 130mm
▲ QJ4G-25/QJ6-25 type with a removal height of 115mm
