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.

Technical field
The invention belongs to the low-tension switch electric appliance technical field, particularly relate to a kind of isolating switch fuse group.
Background technology
Isolating switch fuse group is a kind of multipole manual operation switch, is widely used in that low pressure becomes, in the distribution system, and it can connection under the circuit condition of regulation, carrying and breaking current.Fig. 1 is a kind of isolating switch fuse group part-structure stereogram of prior art.As shown in Figure 1, the isolating switch fuse group of this prior art comprises the cube shaped housing 1 that the upper end is opening-like; Be installed in the inside of housing 1 and a plurality of conductive components 2 that constitute by the series connection of multipole switch and fuse; One end is arranged on outside one side of housing 1, and the other end runs through a plurality of major loop binding posts 3 that link to each other with above-mentioned a plurality of conductive components 2 respectively behind the housing 1; The bottom is arranged on the inside of housing 1, and top is outwards outstanding from the upper end open of housing 1, is used to the handle connecting rod 4 of controlling above-mentioned multipole switch branch, closing; And a not shown end is connected the outer end of handle connecting rod 4, is used for the handle of turning handle connecting rod 4.When this isolating switch fuse group was in the separating brake position, handle was the level of state; And when isolating switch fuse group was in closing position, handle was vertical state.But, there is following point in the isolating switch fuse group of this prior art: as mentioned above, the upper end of housing 1 is formed with opening, therefore be installed in conductive component 2 long-term the exposing outside of housing 1 inside, so, when operating personnel move handle with hand, might touch conductive component 2, so just very easily cause personal injury operating personnel.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of isolating switch fuse group that has protective cover that can effectively improve the product safety in utilization.
In order to achieve the above object, the isolating switch fuse group that has protective cover provided by the invention comprises the cube shaped housing that the upper end is opening-like; Be installed in the inside of housing and a plurality of conductive components that constitute by the series connection of multipole switch and fuse; Be arranged on outside one side of housing, and a plurality of major loop binding posts that link to each other with above-mentioned a plurality of conductive components respectively; One end is arranged on the inside of housing, and the other end is outwards outstanding from the upper end open of housing, is used to the handle connecting rod of controlling above-mentioned multipole switch branch, closing; And one end be connected the outer end of handle connecting rod, be used for the handle of turning handle connecting rod; The described isolating switch fuse group that has protective cover comprises that also one is installed in the upper end open place of housing and is tabular protective cover, and is formed with a perforate that is used to run through the handle connecting rod on the protective cover.
The right lower quadrant edge of perforate caves inward and is formed with one and is circular arc and pairing central angle is the groove at right angle on the described protective cover outer surface, is installed in simultaneously that handle medial surface corresponding site on the handle connecting rod is outwards outstanding to be formed with a hanging locking device that can be embedded in this groove.
Also be formed with a plurality of grids on the described protective cover, be used for the heat radiation of enclosure interior conductive component.
Also be formed with a plurality of screws on the described protective cover.
The isolating switch fuse group that has protective cover provided by the invention is that the opening part at original isolating switch fuse group upper shell is provided with a protective cover, thereby the conductive component and the space outerpace of enclosure interior are kept apart, when operating personnel move handle with hand, just can not touch conductive component like this, so fail safe is good.In addition, owing to be formed with grid on the protective cover, so the heat that conductive component when work produces can in time discharge by this grid, so can not occur making the too high problem of conductive component temperature rise because of protective cover is set
