The Pressure Relief Valve is a safety device used to protect the Oil Immersed Transformer and other electrical equipment from overpressure, which can prevent the transformer tank from deforming or bursting.

Structure and working principle:

1. The primary structural pressure relief valve type is external spring type, with or without a directional guiding device. Its main components are a spring, valve seat, spring seat, valve housing (cover), marker rod, signal switch (occurrence box), sealing ring, and other parts.

2. Working principde

When an accident occurs inside the oil-immersed transformer, the oil tank’s oil is vaporized, generating a large amount of gas, which makes the internal pressure of the oil tank rise sharply. If the pressure is not released, the fuel tank will deform or burst. Installing the pressure relief valve means that when the pressure in the oil tank rises to the opening pressure of the pressure relief valve, the pressure relief valve opens rapidly within 2ms, making the pressure in the oil tank drop quickly. When the pressure drops to the closing pressure value of the pressure relief valve, the pressure relief valve is closed reliably so that the buoyant force in the oil tank is always maintained, effectively preventing external air, vocht, and other impurities from entering the oil tank; When the pressure relief valve is opened, the marker rod is in the direction of. The upper action and obvious extension of the top cover indicate that the pressure relief valve has been operated. When the pressure relief valve is closed, the marker rod remains in the position after opening, and then it can only be reset manually. Compared with the safety airway, it has the advantages of accurate and reliable movement, no damage to parts after exercise, and no replacement.
