QJ3-80 Transformer Gas Relay Transformer Buchholz Relay

QJ Series Gas Relay 
Gas relay is a main protection device for internal failures of oil-immersed transformers and oil-immersed on-load tap-changers. The gas relay (gas relay) is installed on the connecting pipeline between the transformer and the oil conservator. When the internal fault of the transformer causes the oil to decompose to produce gas or cause the oil flow impulse, the contact of the gas relay is activated to connect the designated control circuit. And send a signal in time or automatically cut off the transformer.
