Current-limiting valve for transformer
A flow control valve is a mechanical flow control type one-way check valve. It is usually installed in the connecting pipe between the transformer and the oil reservoir. When the transformer, due to internal faults or other reasons, causes a large amount of oil overflow or leakage, the flow control valve has the function of "closing as soon as oil flows out". It can immediately cut off the oil path between the oil reservoir and the tank, preventing the oil reservoir from replenishing oil to the tank. It is an ideal auxiliary safety protection device for oil-immersed power transformers.
