The device for polishing the insulation and shielding layer of the screw drive cable of the present invention, on the basis of realizing the functions of cable transmission and cable polishing, simplifies the structure, reduces the volume, and makes the structural arrangement more compact.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to a device for grinding the insulating shielding layer of a screw drive cable. Background technique [0002] 110kV and above voltage level high-voltage cable lines have long line lengths, and the cables need to be spliced ​​to meet the length requirements of the lines. Therefore, sections of high-voltage cables need to be connected through cable intermediate joints. Both ends of the high-voltage cable lines must be connected to the grid. Then both ends need to make cable terminals. [0003] To make high-voltage cable intermediate joints and terminal heads, it is necessary to strip and / or polish the high-voltage cable insulation shielding layer at the high-voltage cable intermediate joints and terminal heads. In the prior art, the stripping / grinding operations are all performed manually, for example, glass sheets are usually used to manually strip the insulating shielding layer...

AI Technical Summary

Problems solved by technology

In the prior art, the exploitation / grinding operations are all carried out manually. For example, glass sheets are usually used to manually exploit the insulation shielding layer of high-voltage cables, and the operation takes a long time.

This kind of operation requires a high level of personnel skills. It is not easy for ordinary operators to exploit the insulation shielding layer of high-voltage cables to meet the process requirements. During the exploitation process, it is easy to produce scratches, waves, different shades, ultra-deep exploitation, etc. on the insulation layer of high-voltage cables. Excessive exploitation causes defects such as incomplete cable insulation, which brings hidden dangers to the installation quality of high-voltage cable intermediate joints and terminal heads, and also brings risks to the safe and reliable operation of high-voltage cable lines

[0004] In addition, the existing device for polishing the cable shielding layer has the following technical problems: 1. The structure is cumbersome, which is not conducive to cost control, and there is greater difficulty in repair and maintenance

2. The structure is not compact, resulting in too large volume, unable to work in a small space
