The pressure relief valve YSF16-55*130KKJ is suitable for oil immersed power transformers, power capacitors, and cut and tap switches to protect the oil tank. The pressure relief valve of the power transformer is located above the transformer. If the transformer oil seeps out from here, it indicates that the oil level of the transformer is too high. If there is not much, it can be left untreated; If too much oil seeps out, the power should be cut off and some oil should be discharged to lower the oil level in the transformer, in order to avoid oil leakage from the relief valve and affect the safety performance of the transformer operation.

When the transformer fails in operation, some of the transformer oil will be vaporized due to overheating of the coil, and the pressure in the oil tank will increase rapidly. At this time, the pressure relief valve YSF16-55*130KKJ quickly acts within 2ms to protect the oil tank from deformation or bursting. When the pressure inside the fuel tank increases again and reaches the opening pressure, the pressure relief valve operates again until the pressure inside the fuel tank drops to normal.

The pressure relief valve YSF16-55*130KKJ can also effectively prevent external air, dust, impurities, water vapor, etc. from entering the running transformer, thus protecting the transformer from damage.

Yoyik supplies different types of relief valve for power plant users, which can be used for the hydraulic system of steam turbines and generators.
