Pressure Relief valve

The function of the transformer pressure relief valve is to automatically open and release some internal pressure when the internal pressure of the transformer exceeds the set value, in order to protect the safe operation of the transformer. Transformers generate a certain amount of heat during operation, which leads to internal oil expansion and increases the internal pressure of the transformer. 

If the internal pressure is too high, it may cause damage or explosion to the transformer. Therefore, installing a pressure relief valve can effectively control the pressure inside the transformer and avoid the danger caused by excessive pressure. When the internal pressure of the transformer exceeds the set value, the pressure relief valve will automatically open, releasing a portion of the internal pressure to maintain the safe operation of the transformer.
