Description

An insulating cover for replacing pole-knife pile head wires

technical field

The invention relates to an insulating cover for replacing pole-knife pile head wires, which belongs to the field of electric live working tools.

Background technique

With the continuous opening up of the electricity market, live work has gradually replaced traditional outage maintenance, and live work will be the development direction of 10kV distribution network maintenance in the future. During live work, when the load switch on the pole is replaced with live electricity, the phase post insulator of the load switch on the pole is closer to the phase post insulator on one side, and the phase post insulator on the other side is closer to the pole. Different potentials may be touched, so isolation between the two phase post insulators is required. The currently used isolation tool is insulating cloth, which is soft, easy to be stained, and has a large annual loss. At the same time, it is difficult to completely isolate the live body when wrapping the load switch post insulator on the post, so the operator needs to use more tools at the height of the pole. Long working hours for insulation and isolation operations virtually increase the work intensity and operational difficulty.

Contents of the invention

The purpose of the present invention is to overcome the defects of the prior art and provide an insulating cover for replacing the pole-knife pile head wire, so that the operator cannot touch objects with different potentials at the same time during the operation, and avoids the operator from contacting the two-phase charged body. Or contact with one-phase electrified body and one-phase grounded body to reduce the occurrence of electric shock accident rate.

The technical solution to achieve the above purpose is: an insulating cover for replacing the pile head line of the pole cutter, including a lower side plate, a top plate, a rear plate, an upper side plate and an inserting plate, wherein:

The lower side board and the upper side board are arranged vertically respectively, the top board and the inserting board are arranged horizontally respectively, and the rear board is arranged vertically;

The upper side plate and the lower side plate are located above and below the top plate, and the top end of the lower side plate is fixed on the front end of the top plate; the bottom end of the upper side plate is fixed on the top plate the backend of

The rear surface of the upper side plate is provided with an insulating slot, the front end of the plug-in board is plugged into the insulating slot, and the right end of the plug-in board is provided with a circular arched opening;

The front end of the back plate is fixed on the left end of the lower side plate, the top end of the back plate is fixed on the left end of the top plate, and an insulating handle is arranged on the left side of the back plate.

The above-mentioned insulating cover for replacing the pole-knife pile head line, wherein, the lower side plate, the top plate, the rear plate, the upper side plate and the inserting plate are all made of polypropylene insulating boards.

The above-mentioned insulating cover for replacing the pole-knife pile head line, wherein, the right end of the upper side plate is provided with a horizontally arranged long strip opening, and the front surface of the upper side plate is provided with an insulating bracket. The insulating support includes a semicircular plate and a vertical plate, the rear end of the semicircular plate is fixed on the top of the vertical plate, the vertical plate is fixed on the front surface of the upper side plate, and the vertical plate is located directly in front of the elongated opening.

The insulating cover used for replacing pole-knife pile head wires of the present invention isolates the two-phase post insulators, so that the operator cannot touch objects with different potentials at the same time during the operation, and avoids the operator from contacting the two-phase charged body or one phase. The contact between the charged body and a phase grounding body reduces the occurrence of electric shock accidents.

detailed description

In order to enable those skilled in the art to better understand the technical solution of the present invention, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

Please refer to Fig. 1 and Fig. 2, the best embodiment of the present invention, a kind of insulation cover that is used to replace pole cutter pile head wire, comprises lower side board 1, top board 2, rear board, upper side board 4 and inserting board 5 .

The lower side plate 1 and the upper side plate 4 are arranged vertically respectively, the top plate 2 and the inserting plate 5 are arranged horizontally respectively, and the rear plate is arranged vertically; the upper side plate 4 and the lower side plate 1 are located above and below the top plate 2, and The top of the lower side plate 1 is fixed on the front end of the top plate 2; the bottom end of the upper side plate 4 is fixed on the rear end of the top plate 2; In the insulation slot, a circular arched opening 51 is provided at the right end of the plugboard 5 for good fit between the plugboard 5 and the post insulator to be isolated, and to isolate the whole post insulator; the front end of the rear board is fixed on the lower side board 1 At the left end, the top of the back plate is fixed on the left end of the top plate 2, and an insulating handle 3 is arranged on the left side of the back plate, which is convenient for the operator to place and retrieve the insulating cover.
