YSF-25/50 Pressure Relief Valve
- Details
YSF Series Ф50mm the following diameter pressure release valve is a new pressure release valve, and has applied for patents. This product is oil-immersed electrical equipment used to protect the oil chamber, such as transformers, high voltage switchgear, power capacitors, reactors,load tap switch
Type：YSF-25~50
Injection aperture（mm）：25-50mm
Working pressure range（bar）：0.2~0.7
Application：
The pressure release valve is suitable for oil-immersed power transformer, power capacitor and intercepting switch to protect the oil tank.
When the oil-immersed transformer fails in operation, because of the coil overheating, part of the transformer is electrified, and the pressure in the transformer tank increases rapidly. At this time, the pressure release valve moves quickly within 2ms to protect the tank from deformation or burst. When the pressure in the tank rises again and reaches the opening pressure, the pressure release valve operates again until the pressure in the tank drops to normal. At the same time, it can also effectively prevent the external air, dust, impurities, water vapor and other entry into the running transformer, so as to protect the transformer from damage.
