Title:
SWITCHGEAR CABINET BUSBAR SLEEVE STRUCTURE AND SWITCHGEAR CABINET
Document Type and Number:
WIPO Patent Application WO/2021/143189
Kind Code:
A1
Abstract:
A switchgear cabinet busbar sleeve structure and a switchgear cabinet. In the present application, a busbar fixing member (200) is configured to gradually expand from one open end of the other open end. A busbar (10) forms an included angle (a) with the inner wall (202) of the busbar fixing member (200) when passing through the busbar fixing member (200), so that the surface electric field intensity of the busbar fixing member (200) is greatly reduced, and even if there is a water film on the insulating surface of a sleeve, the occurrence of arcs can be effectively inhibited, thereby solving the ubiquitous problem of insulation vulnerability of the sleeve of a switchgear cabinet. In addition, the pollution flashover voltage and wet flashover voltage of the sleeve are remarkably improved, and the dehumidification requirement for the environment is reduced, thus helping to reduce the operation cost of the switchgear cabinet, and improving the operational reliability of the switchgear cabinet.
