Product Description
(1) The function of a Gas Relay is to signal the operator or cut off the power supply to protect the transformer in the event of insulation failure, wire short circuit, and core burning.
(2) Basic working principle: composed of an open cup and a dry spring contact, acting on the signal. Gas relays consist of baffles, springs, dry spring contacts, etc., which act on tripping.
The gas relay is an important safety protection device on the Oil Immersed Transformer. It is installed on the joint pipe between the transformer tank cover and the oil conservator. Under the action of the gas or oil flow generated by the internal fault of the transformer, the signal or trip circuit is connected to enable the relevant devices to send alarm signals or remove the transformer from the power grid to protect the transformer.
