Title:

COMPACT AND SMALL NORMAL-PRESSURE SEALED AIR-INSULATED SWITCH CABINET

Document Type and Number:

WIPO Patent Application WO/2021/000660

Kind Code:

A1

Abstract:

Disclosed in the present application is a compact and small normal-pressure sealed air-insulated switch cabinet, comprising a secondary chamber, a mechanism chamber, a primary partially-sealed chamber, and a cable chamber, wherein the primary partially-sealed chamber comprises a sealed box and a switch frame; the phase-to-phase insulation of the sealed box is air insulation; the switch frame is made of an insulation material and supports the entire sealed box; the sealed box comprises a front plate, a rear plate, a left side plate and a right side plate; the switch frame is located between the front plate and the rear plate; and both the front plate and the rear plate are made of an insulation material. According to the present application, by means of providing the switch frame, inside the primary partially-sealed chamber, with integrated insulation and support functions, the primary partially-sealed chamber has a more compact structure to improve the space utilization rate; the use of a specially designed flat mechanism greatly reduces the thickness of the mechanism; and with the integrated design of the switch frame, the switch cabinet has a greatly reduced depth, thereby reducing the area of land occupied, increasing the cost-effectiveness, and solving the problem of applying same under special site conditions.
