Abstract:
Provide are: a pressure release device which can limit the damage from an accident and with which the cost of manufacturing a gas insulated opening/closing device can be reduced; and a gas insulated opening/closing device. The pressure release device is for use in the gas insulated opening/closing device that includes a pressure vessel 1 which is a cast object and which is sealed. The gas insulated opening/closing device includes the pressure vessel 1 which is a cast object and which is sealed, and in a case where an accident occurs inside the pressure vessel 1, the device opens the pressure vessel 1 if the internal pressure of the pressure vessel 1 is higher than the internal pressure of the pressure vessel 1 at the time of an accident-clearance of a main protective relay and is less than a destruction-limiting pressure of the pressure vessel 1.
