Abstract
The utility model discloses a protection tool for a low-voltage switch. The protection tool for a low-voltage switch comprises a rectangular box body with an opening on the bottom. A rectangular gap is arranged on the lower portions of both the left side and the right side of the rectangular box body. The bottom edges of the left and right rectangular gaps are respectively provided with two slots. During the maintenance for a low-voltage switch, the protection tool of the utility model is covered on an adjacent low-voltage switch, thereby preventing a maintenance worker from an electric shock caused by touching the exposed electrified portion of the adjacent low-voltage switch, and improving the safety for electrified operation in a power distribution system. Meanwhile, the protection tool is of a reasonable structure and design, and occupies little space, so that enough space is provided to the maintenance worker for maintenance.
Description
Technical field
The utility model relates to a kind of low tension switch protection tool.
Background technology
In recent years, along with many new sub-districts continue to bring out, corresponding low-voltage distribution station is also built following closely and is put into operation, and the low tension switch of 0.4KV is also more and more, because the electric pressure of low tension switch has only 380V, just can guarantee safe distance not touching under the surface condition.So, when this type of switch is overhauled, often ignore the importance that safety measure is implemented, there is certain potential safety hazard.
Power distribution station is mainly based on switchyard, looped network station, open air station at present, wherein the open air station has accounted for more than 90% of power distribution station sum again, in the open air station mainly based on 0.4 kilovolt of low tension switch, when low tension switch of maintenance, the charged connecting portion of inlet wire and busbar is exposed outside on the adjacent low tension switch, following outlet and cable connection point are exposed too outside, and be very dangerous.Exist the potential safety hazard that the exposed live part of having touched adjacent low tension switch owing to the maintainer causes electric shock.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art and a kind of low tension switch protection tool is provided, and during maintenance, this protection tool is covered on the adjacent low tension switch, has guaranteed maintainer's handling safety.
The purpose of this utility model is achieved in that
A kind of low tension switch protection tool of the present utility model, this protection tool comprises the rectangle box body of a bottom surface opening, the latter half of these left and right two sides of rectangle box body all has a rectangle breach, and is respectively equipped with two slots on the base of and arranged on left and right sides rectangle breach.
Above-mentioned low tension switch protection tool, wherein, the position of two slots of described left surface and the position of two slots of right flank are left-right symmetric and distribute.
The beneficial effects of the utility model are: during the low tension switch maintenance, the utility model protection tool is covered on the adjacent low tension switch, cause electric shock because of the exposed live part of having touched adjacent low tension switch when having avoided the maintainer to operate, improved in the distribution system, the fail safe of hot line job, simultaneously because the utility model protection tool reasonable in design, take up an area of for a short time, make the maintainer when overhauling, have enough spaces to carry out service work.
Description of drawings
Fig. 1 is the stereogram in the utility model low tension switch protection tool left side;
Fig. 2 is the stereogram on the utility model low tension switch protection tool right side.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, there is shown the utility model low tension switch protection tool, the rectangle box body 1 that comprises a bottom surface opening, the latter half of this rectangle box body 1 left surface has a rectangular left breach 21, the latter half of right flank also has a rectangular right breach 22 accordingly, also have on the base of two left slots 31, left breach on the base of left side breach and also have two right slots 32 accordingly, and the position of two left slots 31 and two right slots 32 is left-right symmetric and distributes.
Operation principle: during maintenance, the maintainer covers in the utility model protection tool on the adjacent low tension switch in the mode that left surface makes progress or right flank makes progress, left side slot 31 and right slot 32 just in time are arranged in the low tension switch slot place at two ends up and down, make the utility model protection tool cover on the low tension switch firmly, when having avoided the maintainer to operate because of the exposed live part of having touched adjacent low tension switch causes electric shock, because the maintainer can begin the low tension switch of needs maintenance is carried out inspection operation.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
Claims (2)
1. low tension switch protection tool, it is characterized in that, described protection tool comprises the rectangle box body of a bottom surface opening, and the latter half of these left and right two sides of rectangle box body all has a rectangle breach, and is respectively equipped with two slots on the base of and arranged on left and right sides rectangle breach.
2. low tension switch protection tool as claimed in claim 1 is characterized in that, the position of two slots of described left surface and the position of two slots of right flank are left-right symmetric and distribute.
