Problems solved by technology
[0004] However, since there are multiple inflatable tanks placed in the cabinet, and the tank bodies of the inflatable tanks are usually made of metal materials, when the outside ground vibrates, the inflatable tanks are easy to shake, and sparks are likely to be generated when the shaking metal tanks come into contact with other objects , there is a certain security risk

The invention relates to the technical field of gas-insulated switchgears, and discloses a safety gas-insulated switchgear with an insulation protection device, which comprises a switchgear body, a placement cavity is arranged in the switchgear body, at least one insulation protection device is arranged in the placement cavity, the insulation protection device comprises a partition plate, the partition plate is fixedly arranged in the switchgear body, and the insulation protection device is arranged in the partition plate. An insulating air bag is fixedly mounted on the partition plate, the insulating air bag is arranged to be rectangular, and a plurality of inflation tanks are arranged in the placement cavity; the multiple inflation tanks can be separated through the partition plates, so that mutual collision between the inflation tanks is avoided, air can be conveyed into the insulation air bags through the air conveying mechanism, the insulation air bags are expanded, the inflation tanks are fixed, and electric sparks caused by shaking of the inflation tanks when the ground vibrates are avoided; and gas in the insulating gas bag can be pumped out through the gas conveying mechanism, so that the inflation tank can be taken out or put into the placement cavity.
Description
technical field [0001] The invention relates to the technical field of inflatable cabinets, in particular to a safety inflatable cabinet with an insulating protection device. Background technique [0002] Inflatable cabinet is the abbreviation of indoor AC high-voltage gas-insulated gold-enclosed switchgear. It is a new generation of switchgear. The main switch can be either a vacuum circuit breaker with a permanent magnet mechanism or a vacuum circuit breaker with a spring mechanism. The inflatable cabinet has a compact structure. , flexible operation, reliable interlocking characteristics, suitable for different occasions, such as small secondary substations, opening and closing stations, box-type substations and residential quarters in power systems, especially for airports, subways, railways, etc. occasions with higher requirements. [0003] Chinese patent CN208385904U discloses a new type of insulating safety inflatable cabinet, which includes a cabinet body, an inflat...
