The sealing gasket is used to ensure that the insulating oil does not leak. The pressure relief valve mainly uses two springs to exert pressure on the membrane disc, and the membrane disc is sealed by two sealing rings. When there is a fault inside the transformer and a large amount of gas is generated, when the pressure of insulating oil on the membrane disc is greater than the spring pressure, the transformer oil will be discharged when the opening pressure is reached, and the internal pressure of the t…
