Description
Product description: QJS35 series is a series of double-floating ball gas relays with memory function. This series is upgraded to double floating ball structure on the basis of traditional relay, and adds trip memory function, manual reset function and oil shortage alarm function. When the amount of gas in the transformer exceeds the standard, the relay light gas sends out an alarm signal. When the internal fault of the transformer occurs and the flow rate reaches the set value, the relay heavy gas closes and cuts of the power supply oil the transformer.When the fault oil level of the transformer is reduced, the relay sends out a signal alarm.
