Abstract

PURPOSE:To make it possible to release abnormal pressure in a tank into a stay without increasing the size of a machine, protect the tank from damage, prevent the outside dispersion of a cooling medium, an insulation medium and decomposition gas and reduce the cooling medium and the insulation medium as well. CONSTITUTION:A pressure release device 5 is mounted at a specified position on a side wall of a tank 2 by means of a static induction instrument with which a stay 4 is mounted outside the tank 2 which houses perfluorocarbon (cooling medium and insulation medium) 1 whose contents are submerged therein. At the same time, a reinformed stay 6 of the tank 2 is installed in a dead space inside the tank 2 while a penetration hole 7 is installed to the tank 2 where the hole 7 communicates with the stay's interior whose pressure is specified as abnormal pressure of the tank and lower. This construction makes it possible to form a pressure release space during abnormal internal pressure without increasing the size and weight of equipment.

2. Description of the Related Art According to the prior art, a nonflammable liquid such as perfluorocarbon is put as a cooling / insulating medium in a container constituted by an insulating cylinder, and a winding and an iron core are immersed in the container to make the insulating cylindrical container into a tank. In the system in which the insulation medium such as SF 6 gas is sealed between the container and the tank at the same pressure as in the insulation cylinder, the abnormal pressure due to an internal abnormality in the insulation cylinder is controlled by the pressure relief device. The pressure is released to the side of SF 6 through (JP-A-1-166517).
