Modular movable-type solid insulated switchgear

Abstract

The invention discloses modularized movable-type solid insulated switchgear and solves the problems of large size, poor power supply continuity and the like of existing switchgear. The technical key points are as follows: all electrified primary conductive elements and busbars in a power chamber module box body, a busbar chamber module box and a cable chamber module box are respectively wrapped and packaged into cabinet modules by adopting solid insulting medium, a power chamber module is connected with the cable chamber module and the busbar module through positioning parts to form an integral structure, and the modules are mutually separated by metal separators in a closed manner; the power chamber module is positioned above the front part of a cabinet body, the busbar chamber module is positioned above the rear part of the cabinet body, the cable chamber module is positioned on the lower part of the cabinet body, conductive or semi-conductive shielding layers are coated on the surfaces of the modules and can be directly and reliably grounded. The modularized movable-type solid insulated switchgear has the advantages that the structure is compact, the design is reasonable, the modularization of parts is realized, the insulation strength is high, the interchangeability is good, the on-site mounting and debugging are convenient, and the use is safe and reliable, and the purposes of on-site combination, mounting against a wall and maintenance in front of the cabinet are achieved.

Description

technical field [0001] The invention relates to an indoor middle-mounted handcart removable switchgear, in particular to a small and medium-sized modularized removable solid insulated switchgear suitable for 12-24Kv, 50Hz three-phase AC power grid. It is mainly applicable to urban buildings, shopping malls, public utilities, airports, railways, transportation, coal, chemical industry, steel, industrial and mining enterprises, transmission substations and power plants, etc. Background technique [0002] At present, the switchgear of the prior art can be divided into: fixed switchgear and removable switchgear according to the structure; according to the insulation medium, it can be divided into: air, gas and composite insulation. The primary electrical components and conductive circuits of air-insulated switchgear are exposed to the air, which is large in size and poor in environmental resistance, and is suitable for general operating environments. The electrical components a...
