How is the scope of eligibility defined? Gas relay, also known as gas relay, is a component that uses the hot oil flow and hot air flow generated by the fault in the transformer to promote the action of the relay and is a protective component of the transformer; the gas relay is installed in the pipeline between the oil pillow and the oil tank of the transformer; if A discharge fault occurs in the oil-filled transformer. The discharge arc decomposes the transformer oil, producing methane, acetylene, hydrogen, carbon monoxide, carbon dioxide, ethylene, ethane, and other characteristic gases. These gases rise from the inside of the transformer to the upper oil after being generated. In the process of pillow, it flows through the gas relay; if the amount of gas is small, the gas accumulates in the gas relay, causing the float to fall, closing the normally open contact of the relay, acting on the light gas protection to issue a warning signal; if the gas volume is large The oil and gas quickly rushes out through the gas relay and pushes the inner block of the gas relay to close the other group of normally open contacts. The heavy gas directly starts the relay protection trip, opens the circuit breaker, and removes the faulty transformer. The equipment for testing the gas relay is "GYRLC-8YQ Gas Relay Calibrator" of Hengxin Guoyi Technology. The technical parameters of a normal gas relay are as follows: QJ25: light gas: less than 250ml, and heavy gas at 1.0m/s. QJ50: light gas: within 250ml-300ml, heavy gas within 0.6m/s-1.2m/s. QJ80: Light gas: within 250ml-300ml, heavy gas is 0.7m/s-1.5m/s.
