Abstract

The invention provides an inflatable compound insulated switch cabinet, which comprises a cabinet body, a cable chamber, a three-station operating mechanism, an closed gas box and an instrument chamber, wherein the cable chamber is arranged at lower part of the cabinet body, the closed gas box is arranged at an upper part position at the rear end in the cabinet body, vacuum circuit breakers are arranged in the closed gas box, vacuum circuit breaker operating mechanisms are arranged on the closed gas box, the upper part position at the front end in the cabinet body is sequentially provided with the instrument chamber and the three-station operating mechanism from top to bottom, each component in the cabinet body is provided with a conductive connector electrically connected with a lead wire, an insulating layer is arranged on each conductive connector when the conductive connector is connected with the corresponding lead wire. Since the surface of the conductive connector electrically connected with the corresponding lead wire on each component in the cabinet body is provided with the insulating layer, the insulating capacity of the switch cabinet is enhanced, and the cabinet combination of the inflatable compound insulated switch cabinet and the existing SF6 ring network cabinet of a user can be realized.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to an inflatable composite insulated switch cabinet. Background technique [0002] With the rapid development of the national economy, the environmental pollution is becoming more and more serious, and the haze weather has increased significantly. In addition, in order to save the floor area, the switch cabinets in the substation are all designed to be compact, so their insulation protection is particularly important. The insulation properties of the nitrogen and dry air composite insulation medium are far lower than that of SF6 gas. At the same time, in order to meet the problem of combining with the user's existing SF6 ring network cabinet, the depth of the gas box should be kept unchanged as much as possible, and the position of the bus connector should be kept unchanged. Therefore, it is necessary to improve the insulation capacity of the disconnector and solve the probl...
