ZQJSeriesGasThe relay is a protective device that uses the oil flow and gas flow generated during a fault in the transformer to drive the relay action.ZQJGasThe relay is installed on the connecting pipeline between the transformer and the oil storage tank. When a fault occurs inside the transformer causing oil to decompose and generate gas or create an oil flow impulse, the gas relay's contacts act, driving the corresponding alarm or tripping circuit. This device can also be used as a protective device for on-load voltage regulation switches.-
