Problems solved by technology
When the insulated switchgear is in operation, heat will be generated in the gas box, which will cause the gas in the gas box to expand due to heat. Since the gas box of the insulated switchgear is sealed by welding, long-term thermal expansion will cause the inner wall of the gas box to withstand the increase of gas pressure. Large, it may affect the sealing performance of the gas box, thereby affecting the normal operation of the insulating switchgear

The invention discloses environment-friendly gas insulated switchgear which comprises a gas tank, the gas tank is in contact with a mechanism chamber, a gas storage chamber is arranged on the lower side of the gas tank, a switching device in the gas tank is connected with an operating device in the mechanism chamber, and a gas storage device is arranged in the gas storage chamber. The gas storage device is connected with the sealed gas tank through the gas pressure adjusting device, a sealing layer is arranged on the inner wall of the gas tank, the gas pressure adjusting device and the gas storage device are both electrically connected with the microcontroller, the rigid adjusting pipe is connected between the gas tank and the gas storage chamber, the transmission rod is arranged in the rigid adjusting pipe, and a sealing disc is arranged on the transmission rod. The sealing layer is arranged on the inner wall of the gas tank, gas leakage in the gas tank is effectively prevented, the gas pressure in the gas tank is adjusted by sliding the sealing disc in the rigid adjusting pipe, the gas pressure in the gas tank is in a stable state, the deformation of the gas tank is reduced, and the gas tank has a better sealing effect and better insulating performance.
Description
technical field [0001] The invention relates to the technical field of switchgear, in particular to an environment-friendly gas insulated switchgear. Background technique [0002] With the continuous development of social economy, engineering construction is becoming more and more complex, and users have higher and higher requirements for miniaturization, maintenance-free and intelligent switchgear. Conventional switchgear is bulky and heavy, and does not meet the requirements for use in harsh environmental conditions such as high altitude, humidity, and pollution. In this context, gas insulated switchgear came into being. At present, most gas-insulated switchgear uses SF6 gas as the insulation or breaking medium of high-voltage live parts, but with global warming, the United Nations has passed the "Kyoto Protocol" to limit the emission of greenhouse gases such as carbon dioxide, methane, and SF6. When the insulated switchgear is in operation, heat will be generated in the...
