Description

High-voltage cable breakage marking device

Technical Field

The invention relates to the technical field of high-voltage cable detection equipment, in particular to a high-voltage cable breakage marking device.

Background

High tension transmission line is difficult to avoid taking place to collide with scratch wire or wire itself in the work progress and just has outstanding metallics, forms local corona discharge point, and corona discharge can cause a large amount of losses of electric energy in transportation process, can only roughly fix a position unusual loss cable among the traditional art, can't fix a position specific damaged department, nevertheless because high tension cable overlength, and large-scale change cable is unrealistic, therefore need design one kind can carry out the location mark to the cable of unusual discharge loss and do benefit to the prosthetic device in later stage.

Disclosure of Invention

The present invention is directed to solving the above-mentioned problems and to providing a high-voltage cable breakage marking device.

In order to achieve the purpose, the invention adopts the following technical scheme:

the extension part is integrally formed by a container and an extension part;

a colorant is filled in the container;

a liquid level regulating part is arranged on the shell;

at least one roller is arranged on one side of the extension part close to the inside, and a film is sleeved on the outer surface of the roller.

Optionally, the extension portion adopts a fan-shaped structure.

Optionally, the extension is of annular configuration.

Optionally, the film is a non-polar film and the colorant is a polar colorant.

Optionally, the liquid level adjusting part is composed of a lead screw, a nut and a piston, the nut is in threaded fit with the lead screw and is fixedly connected to the container, and the piston is located in the container and is fixedly connected with the end of the lead screw.

Compared with the prior art, the invention has the following advantages:

the invention carries out targeted mark detection design aiming at the condition of corona discharge of a high-voltage cable, when a non-polar film rolls from the high-voltage cable with abnormal corona discharge, the surface of the non-polar film becomes rough and has molecule polarization, the surface of the processed film is fully soaked by a polar solvent according to a similar compatibility principle and is marked on the surface of the cable with abnormal discharge, and a worker carries out targeted repair treatment on the polarity of the marked cable.

Detailed Description

Example one

Referring to fig. 1, the housing 1 is formed by integrally molding a container 11 and an extension 12, and the container 11 and the extension 12 may be made of an insulating material, such as a plastic material.

In this embodiment, the extension portion 12 is a fan-shaped structure, and can be in contact with most of the surface of the cable, and can be disposed on the surface of the cable without threading.

The container 11 is filled with a colorant, the colorant is a polar colorant, and can adopt a common colorant on the market such as rutile titanium dioxide, and the like, at least one roller 2 is arranged on one side of the extension portion 12 close to the inner side, and a film is sleeved on the outer surface of the roller 2, the film is a nonpolar film, and can adopt materials such as BOPP, BOPE and the like.

The polar colorant takes rutile titanium dioxide as a main component, the nonpolar film takes BOPP as an example, the rutile titanium dioxide cannot be attached to the BOPP film when the rutile titanium dioxide is contacted with the BOPP film, so that the rutile titanium dioxide cannot be printed on the surface of the cable when the BOPP film rolls along the surface of the cable along with the roller 2, when the cable is subjected to corona discharge due to damage and the like, the surface of the BOPP generates free radical reaction to cause the polymer to be crosslinked, the surface molecular structure of the BOPP is changed, the surface is polarized and roughened, the wettability of the rutile titanium dioxide is increased according to the principle of 'similar compatibility', the rutile titanium dioxide can be attached to the surface of the cable to be marked when the BOPP film rolls along the surface of the cable along with the roller 2, a worker repairs the cable according to the mark, and only needs to cover a new film on the original corona-treated film or tear off and replace the original film in the subsequent use, can be used again.

Example two

The difference between this embodiment and the first embodiment is that the extension portion 12 is of an annular structure, which can realize annular detection and has a larger detection area than the first embodiment, but requires threading installation.

In the first and second embodiments, the housing 1 is provided with the liquid level adjusting member 3, the liquid level adjusting member 3 is composed of the screw rod 31, the nut 32 and the piston 33, the nut 32 is in threaded engagement with the screw rod 31, the nut 32 is fixedly connected to the container 11, and the piston 33 is positioned in the container 11 and is fixedly connected to the end of the screw rod 31. The level control member 3 plays two roles: firstly, the liquid level of the colorant in the shell 1 is adjusted, the colorant is always in contact with the surface of the film through adjustment, secondly, the effect of adjusting the pressure in the shell 1 can be achieved, the colorant on the upper part can flow out under the action of gravity for the extension part 12 adopting an annular structure, but the pressure in the shell 1 is adjusted through the liquid level adjusting part 3, so that the colorant is less than or equal to the external atmospheric pressure, the colorant cannot flow out of the shell 1, and liquid leakage is avoided.

EXAMPLE III

On the basis of the first embodiment and the second embodiment, the device can be arranged on an unmanned aerial vehicle, so that the high-altitude cable positioning detection can be carried out instead of manpower, and the device can be repaired by matching with cable equipment and methods known in the market.
