Pressure relief valve
The pressure release valve is suitable for oil- _immersed power transformers, power capacitors and on-load tap changers, etc., to protect the oil tank. When an oil-immersed transformer fails during operation, due to the overheating of the coil, part of the transformer is vaporized, and the pressure in the transformer tank increases rapidly. At this time, the pressure release valve operates quickly within 2ms to protect the tank from deformation or bursting. When the pressure in the fuel tank rises again to reach the opening pressure, the pressure release valve will act again until the pressure in the fuel tank drops to a normal value. Since the pressure release valve can be reliably closed after the action, the water and air outside the oil tank cannot enter the oil tank, and the inside of the transformer will not be polluted by the atmosphere.
