G1 pressure relief valve

Pressure relief valve has pressure protection function:

It can quickly open when the pressure inside the transformer exceeds the safety threshold, release the pressure, effectively prevent the transformer from serious accidents such as tank deformation and rupture due to excessive internal pressure, and protect the safe operation of the transformer. After the pressure release, when the pressure returns to the normal range, it can be closed automatically and restored to the initial state without manual intervention, which is convenient for the subsequent operation and maintenance of the transformer.
