Abstract

PURPOSE: To release high pressure occurred internally in an oil-filled electric equipment due to internal maldunction by the damage of reinforcing glass of a partition wall of a hollow container reduced internally under pressure and mounted within the equipment.
CONSTITUTION: A high pressure releasing device 1 is provided within the tank of an oil-filled electric equipment such as a transformer to retain the hollow portion 2 in vacuum with a destroying unit 5 provided at part of a hollow container 4 formed of reinforcing glass 3. Accordingly, the unit 5 is operated when the internal pressure in the container 4 is increased to thereby destory the point 0 on the partition wall 3b with a trigger needle 6. When the point 0 is destoryed, the glass is damaged instantaneously in entirety due to the characteristics of the glass to cause the container 4 to be crushed due to the pressure P to thereby absorb the pressure increase at the hollow portion reduced under pressure so far.
