Abstract
The utility model relates to an earth potential live-working bolt penetrating device, comprising an insulative operating rod and a plate body vertical to the insulative operating rod, wherein one end of the plate body is fixedly connected with the insulative operating rod, and the other end is provided with a U-shaped opening groove which is used for vertically placing a bolt in a clamping manner. When in use, the insulative operating rod is utilized to deliver the bolt to an electriferous installation position at the earth potential, the suspended-type lightning arrester can be mounted under the circumstances of no power failure in the 35-110kV line. The earth potential live-working bolt penetrating device has the advantages of simple structure, low cost and strong practicability, can effectively reduce the times of the power failure caused by installing the suspended-type lightning arrester and can reduce the probability of the occurrence of various misoperation accidents in the 35-110kV line.
Description
Technical field
The utility model belongs to the live-working safety apparatus, and particularly earth potential live operation bolt pierces into device.
Background technology
At present, when the 35-110kV circuit is installed suspended-type surge arrester, install after need to working line having a power failure, when transmission or not, might cause misoperation fault, misdelivery electrification, even the personnel that can cause get an electric shock, have a strong impact on power supply reliability and stability.Just can effectively avoid circuit to stop the contingency generation of sending electricity to cause but utilize the earth potential live operation to change leakage conductor, yet the installation that the key of lightning arrester is the lightning arrester bolt is installed in the earth potential live operation.For above problem, the utility model proposes a kind of earth potential live operation bolt and pierce into device, utilize the utility model that suspended-type surge arrester can be installed when the 35-110kV circuit is charged, not only reduce the line outage number of times, and effectively reduced the generation of operating accident, misdelivery electrification etc.
The utility model content
The purpose of this utility model is to solve the problem that suspended-type surge arrester is installed in the charged situation of 35-110kV circuit, to reduce the generation of frequency of power cut and misoperation, misdelivery electrification.
The purpose of this utility model is achieved through the following technical solutions:
A kind of earth potential live operation bolt pierces into device, comprises insulating bar and the plate body vertical with insulating bar, and described plate body one end is fixedly connected with insulating bar, and the other end is provided with the U-shaped open slot that card is put bolt;
Further, the described plate body end that is provided with the U-shaped open slot is bent to form the U-shaped structure.
The beneficial effects of the utility model are:
The earth potential live operation bolt that the utility model provides pierces into utensil simple and practical characteristics, has remedied the shortcoming that the circuit suspended-type surge arrester can not be installed in the charged situation.The utility model cost is low, the frequency of power cut that causes when for minimizing the circuit suspended-type surge arrester being installed and the important function that has that reduces various operating accidents.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can from practice of the present utility model, obtain instruction.Target of the present utility model and other advantages can realize and obtain by following specification.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing the utility model is described in further detail, wherein:
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is the structure chart of plate body.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection range of the present utility model.
As shown in the figure, earth potential live operation bolt pierces into device, comprises insulating bar 1 and the plate body 2 vertical with insulating bar, and described plate body 2 one ends are fixedly connected with insulating bar 1, and the other end is provided with the U-shaped open slot 2a that card is put bolt.When suspended-type surge arrester is installed, with being installed, required bolt puts into U-shaped open slot 2a, then in the situation of not cutting off the power supply, utilize insulating bar 1 bolt to be put into the position of the required installation of lightning arrester on the alive circuit at the earth potential place, simultaneously, the operator utilizes spanner with bolt tightening at the earth potential place, when tightening with insulating bar 1 inclination certain angle, just can prevent that bolt from rotating, thereby realize the charged installation of suspended-type surge arrester.
In the present embodiment, the intensity at U-shaped open slot position is set in order to improve plate body, the end that described plate body is provided with U-shaped open slot 2a is bent to form the U-shaped structure, in use, U-shaped bending upper under can.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of the technical program, it all should be encompassed in the middle of the claim scope of the present utility model.
