Problems solved by technology

[0005] A cable is a kind of electrical energy or signal transmission device, usually composed of several wires or groups of wires, in some environments such as overhead lines, because the cable is in a state of tension for a long time, it will be broken after being subjected to extreme tension risk, resulting in significant losses to the grid

Abstract

The invention discloses a self-hardening anti-breaking cable based on power grid power transmission, and belongs to the technical field of power grid power transmission, the self-hardening anti-breaking cable can reinforce an outer sheath by inlaying a middle embedded pipe and a node ball, and the middle embedded pipe can perform an extension compensation effect to a certain extent under the condition that normal stretching and bending actions of the cable are met; under the action of extreme stretching, the middle embedded pipe can generate an excessive compensation action, the water release action of the node ball is triggered by virtue of a trigger line in the middle embedded pipe, then water enters the middle embedded pipe and then is subjected to a hydraulic gelatinization reaction, the middle embedded pipe is promoted to generate a hardening action, and at the moment, the strength of the middle embedded pipe is greatly improved, and therefore, the cable is prevented from being continuously stretched and fractured; and through the water absorption magnetic balls absorbed on the middle embedded pipe, the water leakage phenomenon can be sensed in time, plugging is carried out, the influence of water penetration on the cable is avoided, and the power transmission safety of the cable is greatly ensured.

Description

technical field [0001] The invention relates to the technical field of grid power transmission, and more specifically relates to a self-hardening anti-break cable based on grid power transmission. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network. It includes three units of power transformation, power transmission and power distribution. The task of the power grid is to transmit and distribute electrical energy and to change the voltage. [0003] The transmission line is realized by using a transformer to boost the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as a circuit breaker. Structural forms, transmission lines are divided into overhead transmission lines and cable lines. [0004] The overhead transmission line is composed of line towers, wires, insulators, line fitting...
