System capable of performing electric leakage protection for cable

Abstract

The invention discloses a system capable of performing electric leakage protection for a cable. The system comprises a cable body arranged underground. The outer side of the cable body is provided with a protective layer; a gap is formed between the cable body and the protective layer; the protective layer is protected and separated every 1km through a separator plate; one end of the separator plate is connected with the inner wall of the protective layer, and the other end of the separator plate is connected with the outer wall of the cable body; different alarm modules and detection modulesare arranged in the protective layers of the partitions, and a control center receives signals sent by the alarm modules, monitors the operation condition of the cable in real time and disconnects power transmission of the cable body after receiving the alarm signals of the alarm modules. And various detection modules and alarm modules are arranged in the gap between the cable body and the protective layer, so that the condition of the cable can be detected in time, the detected data can be sent to the control center in real time, and a worker of the control center can know the working condition of each section of the cable.

Description

technical field [0001] The invention relates to an electric leakage protection system, in particular to a system capable of carrying out electric leakage protection on cables. Background technique [0002] Overhead line power supply operation has a relatively high failure rate, high operation and maintenance costs, and low reliability. Now underground power cables are popularized in cities. However, when the insulation layer of the underground power cable is damaged and a leakage fault occurs, it is difficult to judge the leakage situation and location by conventional methods, and a special detection device is required for detection. Leakage detection devices usually use the method of measuring the grounding resistance of cables. Although this method is scientific and has high detection accuracy, it needs to be operated by professionals and is cumbersome.
