Abstract

PURPOSE:To mitigate the rise of inside pressure in a tank to be caused by an inside trouble and to enable to prevent a disaster of the oil-filled electric apparatus by a method wherein the tank being provided with an oil-exhausting port and a water tank being connected to the tank through a pressure release valve are provided, and an incombastible gas is filled in the water tank. CONSTITUTION:The oil-exhausting port 4 is provided on the side wall of the tank 3 containing a transformer main body 1 and an insulating oil 2, and the port is connected to the water tank 7 through the pressure release valve 5. The water tank is consisted of, for example, two tanks 7a, 7b connecting the lower parts, and an outlet 8 for water is provided at the upper part of the tank 7b. Accordingly when a trouble took place in the tank 3 to make the inside pressure to rise making the pressure release valve 5 to operate to make a jet stream of high temperature gas and oil to blow into the water tank 7, cooling water 9 in the water tank 7 is discharged to mitigate the rise of pressure. Moreover because the incombastible gas 11 is filled up at the upper part of the tank 7a, the fear of ignition is not existed, and the secondary disaster like fire, etc., can be prevented.
