Gas Relay Series in Totally-enclosed Transformer Installation and Operation Instruction

概述Summary

QJ 系列型气体继电器，主要用于保护各种类型的油浸式全密封变压器。变压器在运行时，由于内部故障产生气体，气体聚集于气体继电器的集气室内，当气体的容积达到一定程度时，触发报警或切除触点，输出报警信号或切除信号，从而达到保护变压器的目的。

QJ series gas relay is mainly used to protect all kinds of type oil-immersed totally-enclosed transformer. When the transformer is running, the gas gathers in the gas gathering chamber of the gas relay because the inner trouble creates gas. When the volume of the gas reaches a certain degree it triggers the alarm or cutting off the contact, outputs the alarm or cutting off signal and thus reach the aim of protecting the transformer.
