Product description: QJS35 series is a double floating ball gas relay series with memory function. On the basis of traditional relay, this series is upgraded to double floating ball structure, and added tripping memory function, manual reset function and oil shortage alarm function. When the amount of gas in the transformer exceeds the standard value, the light gas relay sends an alarm signal. When the transformer has an internal fault and the flow reaches the set value, the heavy gas relay is closed to cut off the power oil of the transformer. When the fault oil level of the transformer is lowered, the relay sends out an alarm signal.
