The pressure safety valve is employed as a safety element in distribution transformers of low rating. In the event of an explosion-type pressure increase of the transformer tank, the excess pressure must be relieved immediately in order to avoid damage to the tank.These types are suitable for hermetically sealed type transformers.
CONSTRUCTION
The pressure safety valve consists of a brass cap, a conical valve body, a rubber seal between the cap and body and a coil spring holding the whole syste…
