Isolating switch fuse unit with protection cover

Abstract

The invention relates to an isolating switch fuse unit with a protection cover, which comprises a shell, a plurality of conducting parts, a plurality of major loop connecting terminals, a handle connecting rod, a handle and a platelike protection cover installed at the upper end opening part of the shell, and an open hole for penetrating through the handle connecting rod is formed on the protection cover. The isolating switch fuse unit with the protection cover is characterized by arranging one protection cover at the opening part of the upper shell of the traditional isolating switch fuse unit so that conducting parts inside the shell and the outside space are isolated, and thus, when an operator moves the handle by hands, the operator can not touch the conducting parts, and the safety is good. In addition, because a grating is formed on the protection cover, heat produced during the operation of the conducting parts can be exhausted outward in time through the grating, and the problem of over high temperature rise of the conducting parts due to the arrangement of the protection cover is solved.

Description

technical field [0001] The invention belongs to the technical field of low-voltage switchgear, and in particular relates to a fuse group of an isolating switch. Background technique [0002] The isolating switch fuse group is a multi-pole manually operated switch, which is widely used in low-voltage transformation and distribution systems. It can connect, carry and break current under specified circuit conditions. figure 1 It is a three-dimensional view of a partial structure of an isolating switch fuse group in the prior art. Such as figure 1 As shown, this prior art isolating switch fuse set includes a cubic housing 1 with an open upper end; a plurality of conductive components 2 installed inside the housing 1 and composed of multi-pole switches and fuses connected in series One end is arranged on the outer side of the housing 1, and the other end passes through the housing 1 and is respectively connected to the plurality of main circuit terminals 3 connected to the abov...

AI Technical Summary

Problems solved by technology

But, there is following problem in this disconnector fuse group of prior art: as mentioned above, the upper end of casing 1 is formed with opening, so the conductive part 2 that is installed in casing 1 interior is exposed outside for a long time, so, when operator When the handle is moved by hand, it is possible to touch the conductive part 2, which will easily cause personal injury to the operator
