Embodiment Construction

[0041] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0042] refer to figure 1 , figure 2 , image 3 , an underground self-repairing power cable with a breakable node, including a power cable main body 6, the power cable main body 6 is provided with a breakable point 1, the power cable main body 6 is also provided with a redundant section 2, and the redundant section 2 is located in the breakable section The place where point 1 is set; under the action of external force, when easy-break point 1 is broken, easy-break point 1 will not conduct, and redundant section 2 will conduct. In the present invention, an easy-break point 1 is set on the main body 6 of the traditional power cable, and a redundant section 2 is set at the easy-break point 1. After the breakage, the redundant section 2 is automaticall...

Abstract

The invention relates to the technical field of electric power, in particular to an underground self-repairing power cable provided with easily broken nodes. The underground self-repairing power cable provided with the easily broken nodes comprises a power cable body. The power cable body is provided with the easily broken nodes and is further provided with redundant sections, and the redundant sections are located at the easily broken nodes. When the easily broken nodes are broken under the action of external force, the redundant sections instead of the easily broken nodes are switched on. The easily broken nodes are arranged on a body of a traditional power cable, the redundant sections are arranged at the easily broken nodes, after the easily broken nodes are broken, the redundant sections are connected automatically to maintain power supply or signal communication, and therefore the working stability of the traditional power cable is improved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to a cable. Background technique [0002] After the power cable is laid, it is inevitable that it will be pulled and broken due to terrain changes or other external forces. [0003] Traditional power cables cannot achieve the anti-break effect, and once broken, they cannot maintain power supply or signal communication normally. Contents of the invention [0004] The purpose of the present invention is to provide an underground self-repairing power cable provided with a breakable node, so as to solve the technical problem that the traditional power cable cannot realize anti-breakage. [0005] The technical problem solved by the present invention can adopt following technical scheme to realize: [0006] An underground self-repairing power cable with breakable nodes, including a power cable main body, is characterized in that the power cable main body is provided with a brea...
