Abstract

PURPOSE: To prevent a tank from damage caused by an arcing when in a ground fault, by providing a metal tube of high melting point at both ends of inner wall surfaces of the earth tank.
CONSTITUTION: At both end parts of inner wall surfaces of an earth tank 11 in which an insulating gas is sealed, is being provided a metal tube 20a, 20b of high melting point, made of metal material whose melting point is higher than that of the metal material used for the earth tank. When caused a ground fault in the interior of the earth tank, an action of arcing, caused by the above fault, is driven to be spread to an end of the earth tank 11 due to an electro-magnetic force, with the metal tube partially molten. On the other hand, said metal tube provides a less quantity of metal consumption because of its high melting point. Accordingly, no reach of a tip of the arc flame to the inner wall surfaces of the earth tank eliminates a fear of damaging the earth tank.
