Description

Technical Field

[0001] This utility model belongs to the field of high-voltage pulse transmission cable technology, specifically relating to high-voltage pulse transmission cables. Background Technology

[0002] High-voltage pulse transmission cables are special cables used to transmit pulse signals in high-voltage environments, and are widely used in power systems, electronic equipment, proton accelerators, plasma drilling rigs, and other fields. Their design and application involve multiple technical fields, including high-voltage insulation, low-impedance transmission, and pulse signal generation and detection.

[0003] However, the following problems were found in the implementation of the relevant technologies: when high-voltage pulse transmission cables are used, they are subject to friction and impact. The outer surface of most existing high-voltage pulse transmission cables is smooth. When subjected to friction, the location of friction damage is not much different from other locations. Without the use of professional instruments, it is not easy to find the location of damage to the high-voltage pulse transmission cable, which may lead to leakage, short circuit and unsatisfactory transmission effect of the high-voltage pulse transmission cable.

[0004] Therefore, a high-voltage pulse transmission cable is proposed to solve the above problems. Utility Model Content

[0005] This invention proposes a high-voltage pulse transmission cable, which solves the problem in related technologies that it is not easy to find the location of damage to high-voltage pulse transmission cables without the use of professional instruments.

[0006] The technical solution of this utility model is as follows: a high-voltage pulse transmission cable, comprising: a wire core and a wear-resistant layer;

[0007] A warning layer is fixedly installed inside the wear-resistant layer. An insulation layer is wrapped around the outside of the wire core. A semiconductor layer is wrapped around the outside of the insulation layer. A metal shielding layer is wrapped around the outside of the semiconductor layer. A filler layer is filled between the metal shielding layer and the warning layer. Anti-slip grooves are formed on the outer surface of the wear-resistant layer.

[0008] Preferably, the warning layer is made of polyethylene and is yellow in color.

[0009] Preferably, there are multiple anti-slip grooves, and the multiple anti-slip grooves are arranged in a circular array on the outer surface of the wear-resistant layer.

[0010] Preferably, the semiconductor layer is made of semiconductor material and adhesive and is located close to the insulating layer.

[0011] Preferably, the metal shielding layer is made of copper and is woven from copper wire, tightly wrapped around the semiconductor layer.

[0012] Preferably, there are three wire cores, and all three wire cores are located inside the filler layer.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] A yellow warning layer made of polyethylene clearly shows damage to the outer wear-resistant layer, making it easier for workers to identify the location of the high-voltage pulse transmission cable and enabling rapid repair. Multiple anti-slip grooves arranged in a circular array on the wear-resistant layer increase the cable's friction, and the exposed area of ​​these grooves indicates the degree of cable wear. A semiconductor layer made of semiconductor materials and adhesive eliminates the electrostatic field between the outer surface of the insulation layer and the metal shielding layer, reducing the risk of partial discharge. A metal shielding layer woven from copper wire reduces electromagnetic interference during high-voltage pulse transmission and prevents electric shock to operators in case of cable damage, thus protecting their safety.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Implementation

[0023] Please see Figure 1-4. High-voltage pulse transmission cable, including: wire core 1 and abrasion-resistant layer 2;

[0024] The wear-resistant layer 2 has a warning layer 3 fixedly installed inside. The wire core 1 is wrapped with an insulation layer 4. The insulation layer 4 is wrapped with a semiconductor layer 5. The semiconductor layer 5 is wrapped with a metal shielding layer 6. The metal shielding layer 6 and the warning layer 3 are filled with a filling layer 7. The outer surface of the wear-resistant layer 2 is provided with anti-slip grooves 8.

[0025] The technical solution provided in this embodiment is as follows: When using a high-voltage pulse transmission cable, the outer wear-resistant layer 2 will be worn. When the wear-resistant layer 2 is worn to a certain extent, the depth of the anti-slip groove 8 at the rubbed location will differ from the depth of the other anti-slip grooves 8 that are not rubbed, allowing workers to easily see which location has been damaged by friction. When the wear-resistant layer 2 is worn through, a yellow warning layer 3 will be exposed. Then, during inspection, workers can easily see the exposed yellow warning layer 3 of the high-voltage pulse transmission cable and then repair the high-voltage pulse transmission cable.

[0026] Furthermore, warning layer 3 is made of polyethylene and is yellow in color.

[0027] Specifically, the yellow warning layer 3, made of polyethylene, can directly display the yellow warning layer 3 when the outer wear-resistant layer 2 is damaged, making it easier for staff to see the location of the high-voltage pulse transmission cable damage and enabling them to repair it quickly.

[0028] Furthermore, there are multiple anti-slip grooves 8, and the multiple anti-slip grooves 8 are arranged in a circular array on the outer surface of the wear-resistant layer 2.

[0029] Specifically, by creating multiple anti-slip grooves 8 in a circular array on the surface of the wear-resistant layer 2, the friction of the high-voltage pulse transmission cable can be increased, and the degree of cable wear can be determined by the exposed area of ​​the anti-slip grooves 8.

[0030] Furthermore, the semiconductor layer 5 is made of semiconductor material and adhesive and is located close to the insulating layer 4.

[0031] Specifically, the semiconductor layer 5, made of semiconductor material and adhesive, can eliminate the electrostatic field between the outer surface of the insulating layer 4 and the metal shielding layer 6, reducing the risk of partial discharge.

[0032] Furthermore, the metal shielding layer 6 is made of copper and is woven from copper wire, tightly wrapped around the semiconductor layer 5.

[0033] Specifically, the metal shielding layer 6, made of copper wire, can reduce electromagnetic interference during high-voltage pulse transmission cable operation and prevent electric shock to the operator in case of high-voltage cable damage, thereby endangering the operator's personal safety.

[0034] Furthermore, there are three wire cores 1, and all three wire cores 1 are located inside the filling layer 7.

[0035] Specifically, by placing all three conductors 1 inside the filler layer 7, the transmission capacity of the high-voltage pulse transmission cable can be increased, and the stability of the high-voltage pulse transmission cable can also be improved.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
