Product Overview
Description
QJ Gas relay
1、The gas relay is a protective device used in oil-immersed transformers.
2、The gas relay is installed on the connecting pipe between the transformer cover and the oil conservator, and can be equipped with an air guide pipe to realize ground exhaust and sampling.
3、 When the internal failure of the transformer causes oil to decompose to generate gas or cause oil flow to surge, the contact of the relay will act, connect the designated control circuit, and send a signal in time or automatically cut off the transformer.
4、 This relay is a new product improved from Keqi's original QJ series relays. It has the characteristics of good sealing, stable movement structure, sensitive action, and exquisite appearance.
5、 In addition, the lower shell is made of cast steel, which overcomes the defect of cracking caused by the original cast iron material due to pipeline tension, torsion and other stresses and long-term vibration.
