YSF4-35/25KJB Pressure Relief Device

Cấu hình tính năng van giảm áp

Pressure relief valve is suitable for oil immersed power transformer, power capacitor and cut-off and tap changer to protect oil tank.

When the oil immersed transformer fails in operation, some transformer oil is gasified due to the coil overheating, and the pressure in the transformer oil tank increases rapidly. At this time, the pressure relief valve acts quickly within 2ms to protect the oil tank from deformation or burst. When the pressure in the oil tank rises again and reaches the opening pressure, the pressure relief valve operates again until the pressure drops to the normal value. At the same time, it can also effectively prevent external air, dust, impurities and water vapor from entering the running transformer, so as to protect the transformer from damage.
