Product Usage
QJ series gas relay (hereinafter referred to as relay) is a protection device used in oil-immersed transformers, When the oil is decomposed to generate gas or the oil flow surges due to the internal fault of the transformer, the contacts of the relay are activated and the specified Control the loop, and send a signal in time or automatically cut off the transformer.
Working principle
When the transformer is working normally, the relay is filled with transformer oil. If the transformer has a slight fault during operat on, the gas generated by the decomposit on of the transformer oil will gather on the upper part of the relay container and force the relay float to drop. When the float drops to a certain limited position, the magnet will make the signal contact turn on and send an alarm signal If the transformer leaks and the oil level drops, an alarm signal will also be issued. If there is a serious fault inside the transformer, there will be a surge of oil, which wil generate oil flow in the pipeline and impact the movement of the baffle of the relay, When the baffle plate moves to a certain limited position, the magnet makes the trip contact connect, cutting off all the power supply connected with the transformer
