Abstract

The invention discloses a novel inflatable switch cabinet in the technical field of inflatable switch cabinets, which comprises a primary switch element, the primary switch element comprises a sealing thick aluminum plate, and one side of the sealing thick aluminum plate is provided with an isolation grounding operation mechanism and a circuit breaker mechanism. A multi-station isolation grounding switch and a plurality of solid-sealed polar pole assemblies controlled by the multi-station isolation grounding switch are mounted on the other side; the isolation grounding operation mechanism can control the multi-station isolation grounding switch to be closed and grounded, a transmission mechanism and an operation mechanism are integrated on the circuit breaker mechanism, and the operation mechanism can simultaneously control the plurality of solid-sealed polar pole assembly open circuits to be closed through the transmission mechanism. According to the novel inflatable switch cabinet provided by the invention, the mechanism is directly fixed on the sealing thick aluminum plate, a transmission mechanism and an operating mechanism of the vacuum circuit breaker are integrated, a mechanism frame is cancelled, and the mechanism is directly fixed on the sealing thick aluminum plate, so that the mechanism cost of the circuit breaker is reduced.

Description

technical field [0001] The invention relates to a novel inflatable switch cabinet, which belongs to the technical field of inflatable switch cabinets. Background technique [0002] With the continuous advancement of my country's urban network reconstruction project, residents have higher and higher requirements for power supply quality. Therefore, higher requirements are put forward for switches used in various medium-voltage nodes. Modularization, maintenance-free, intelligent, high reliability, and long power life have become the development trend of this type of switch. The emergence and rapid development of C-GIS inflatable switchgear has solved such problems very well. At present, most of the C-GIS inflatable switchgears on the market have problems such as large size, inability to open the gate in an emergency, need to open the door for operation, large temperature rise, large space for the operating mechanism, and high cost. Contents of the invention [0003] The p...
