Abstract
The invention discloses a low voltage switch protection tool. The tool comprises an oblong box body with an opening on the bottom surface, wherein an oblong nick is arranged on the lower half parts of the left and right sides of the oblong box body respectively; and two slots are arranged on the bottom edges of the oblong nicks on the left and right sides respectively. The tool has the following beneficial effects: during low voltage switch maintenance, the tool is covered on the adjacent low voltage switch, thus avoiding electric shock of the maintainers because of touching the bare live part of the adjacent low voltage switch during operation and improving the safety of live operation in the electric distribution system; and as the tool is reasonable in structural design and small in floor area, enough space is provided for the maintainers have to carry out maintenance.
Description
Technical field
The present invention 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 main with switchyard, looped network station, open air station mainly at present; Wherein the open air station has accounted for more than 90% of power distribution station sum again; Be main with 0.4 kilovolt of low tension switch mainly in the open air station, 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 objective of the invention is to overcome the defective of prior art and a kind of low tension switch protection tool is provided, during maintenance, this protection tool is covered on the adjacent low tension switch, guaranteed maintainer's handling safety.
The objective of the invention is to realize like this:
A kind of low tension switch protection tool of the present invention; 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 said left surface and the position of two slots of right flank are left-right symmetric and distribute.
The invention has the beneficial effects as follows: during the low tension switch maintenance; Protection tool of the present invention is covered on the adjacent low tension switch, because of the exposed live part of having touched adjacent low tension switch causes electric shock, improved in the distribution system when having avoided the maintainer to operate; The fail safe of hot line job; Simultaneously because protection tool reasonable in design of the present invention, 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 low tension switch protection tool of the present invention left side;
Fig. 2 is the stereogram on low tension switch protection tool of the present invention right side.
Embodiment
To combine accompanying drawing that the present invention is described further below.
See also Fig. 1; Low tension switch protection tool of the present invention has been shown among the figure; The rectangle box body 1 that comprises a bottom surface opening, the latter half of this rectangle box body 1 left surface have a rectangular left breach 21, and the latter half of right flank also has a rectangular right breach 22 accordingly; Also have on the base of left side breach on the base of two left slots 31, left breach and also have two right slots 32 accordingly, and the position of two left slots 31 and two right slots 32 is the left-right symmetric distribution.
Operation principle: during maintenance; The maintainer covers in protection tool of the present invention on the adjacent low tension switch with the mode that left surface makes progress or right flank makes progress; Left side slot 31 just in time is arranged in the low tension switch slot place at two ends up and down with right slot 32; Make protection tool of the present invention 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 only supplies to explain the present invention's usefulness; But not limitation of the present invention; The technical staff in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited each claim.
Claims (2)
1. low tension switch protection tool; It is characterized in that; Said 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 said left surface and the position of two slots of right flank are left-right symmetric and distribute.
