PURPOSE:To raise the stability of power supply by making the inspection of a pressure sensor possible, and maintaining the breakdown strength property of insulating gas, and preventing the occurrence of accident. CONSTITUTION:A T-type joint 12 is connected between an opening and closing valve 6A and a pressure sensor 8A, and the one side of the opening and closing valve 11 is connected to this T-shaped joint 12. A pneumatic pressure input unit 13 for supplying air to the pressure sensor 8A is connected to the other side of the opening and closing valve 11. A pressure detecting unit 14, a control unit 15, and a display 16 are connected in order to this pneumatic input unit 13, and the display 16 displays the value reduced to the reference temperature of the pressure of the pressure sensor 8A. |
