The transformer accessories mainly include Buchholz Relay, Tap Changer, oil level gauge, Butterfly Valve, Moisture Absorber, pressure reducing valve, Cross Flow Cooling Fan, Bimetal Thermometer, Epoxy Resin Insulator, etc. New and old customers are welcome to purchase and customize.

Structure and working principle:

1. The primary structural type of Pressure Relief Valve is an external spring type, with or without the 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 principle
When an accident occurs inside the Oil immersion transformer, the oil tank's oil is vaporized, generating a large amount of gas, which sharply increases the internal pressure of the oil tank. 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 2, 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, moisture, 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.

purpose
● The product has an electrical alarm signal, which can realize remote monitoring.
● Applicable to liquid or gas-insulated transformers, transformers, on-load tap changers, high-voltage switches, and other electrical products.
● In case of internal failure of electrical equipment, the valve will open to release the pressure in the oil tank to avoid deformation and bursting of the oil tank.
● When the pressure in the tank drops to the valve's closing pressure, the valve will close again to prevent external moisture and impurities from entering the tank.

Service conditions and installation methods
● Ambient temperature: - 30 ℃~40 ℃.
● Installation position:
a) Installed on the fuel tank cap;
b) On the upper side wall of the oil tank;

c) Raise the seat.
