Problems solved by technology

[0002] In the contact box used in the existing switchgear, the female discharge line groove protrudes at the same angle as the upper and lower fixing plates. When in use, a partition needs to be installed between the three-phase contact boxes. If it does not meet the standard, it is easy to generate heat when working, causing accidents such as burning

Abstract

The invention discloses a shielding contact box, which comprises a contact box body, on which a bus outlet slot is arranged, and the bus outlet slot protrudes obliquely to the left or right. The invention has a reasonable structure, effectively increases the air creepage distance between the three-phase contact boxes, has high insulation coefficient, does not need partitions between the three-phase contact boxes, and has good flame retardancy.

Description

technical field [0001] The invention relates to a contact box used in a switch cabinet. Background technique [0002] For the contact box used in the existing switchgear, the female discharge line slot protrudes at the same angle as the upper and lower fixing plates. When in use, a partition needs to be installed between the three-phase contact boxes. If it is not up to the standard, it is easy to generate heat when working, causing accidents such as burning. Contents of the invention [0003] The purpose of the present invention is to provide a shielding contact box with reasonable structure, large air distance between three-phase contact boxes, and good use safety. [0004] Technical solution of the present invention is: [0005] A shielding contact box includes a contact box body, on which a busbar outlet slot is arranged, and the feature is that: the busbar outlet slot protrudes obliquely to the left or right. [0006] The inclination angle of the oblique extension ...
