Gas tank for high altitude type gas insulation ring main unit

The invention discloses a gas tank for a high altitude type gas insulation ring main unit, which comprises a gas tank body and a high voltage switch element arranged in an inner cavity of the gas tank body, a plurality of reinforcing ribs capable of improving the structural strength of the gas tank body are arranged on the surface of the gas tank body, and a through hole is formed in the bottom of the gas tank body. A pressure relief device capable of increasing the pressure relief pressure of the gas tank is mounted on the through hole, and a sealed density meter capable of truly reflecting the actual gas density in the gas tank is mounted on the gas tank body. According to the gas tank for the high-altitude type gas insulation ring main unit, the strength and the pressure endurance capacity of the gas tank body are improved, the gas density of the inner cavity of the gas tank can be accurately measured, the adaptive capacity to the high-altitude environment is completely achieved, the mechanical and electri
