Abstract

The invention discloses a closed gas insulation switch cabinet which comprises a front cabinet, wherein a grounding row is fixedly connected with an inner wall of the front cabinet; one side of the front cabinet is grafted with one side of a cable chamber through a bus bar; a cable pipe is fixedly connected with the bottom of the inner wall of the cable chamber; one end of the cable pipe penetrates through the cable chamber and extends to the exterior of the cable chamber; the top of the cable chamber is grafted with the bottom of a breaker chamber through the bus bar. According to the invention, the front cabinet, the cable chamber, the breaker chamber, a bus bar chamber, a first decompression channel and a second decompression channel are arranged, so that the switch cabinet is not in the integrated metal armoring mode; the problems that the metal armored switch cabinet occupies large area and cannot adapt to metro station and other places with higher requirement for switch cabinet are solved; the switch cabinet can adapt to various places requiring the switch cabinet; the switch cabinet is formed in the manner of bus bar grafting and chambering, so that the switch cabinet can be quickly assembled and disassembled; the switch cabinet is prevented from potential safety hazard.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a closed gas insulated switchgear. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. At present, the existing switchgears on the market are all metal armored. Such switchgears occupy a large area and cannot be used in subways and other places with high requirements for switchgears. Moreover, metal armored switches The cabinet has a complex structure and is inconvenient to disassemble, and there is a great potential safety hazard when ...
