Description

Technical Field

[0001] The invention belongs to the technical field of circuit detection, and in particular relates to a transmission line fault detection device. Background Art

[0002] The transmission line is realized by using a transformer to step up the voltage of the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as circuit breakers. In terms of structural form, the transmission line is divided into overhead transmission lines and cable lines. Overhead transmission lines are composed of line towers, conductors, insulators, line hardware, guy wires, tower foundations, grounding devices, etc., and are erected above the ground. According to the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. In order to ensure the normal use of the transmission line, it is necessary to detect it through a special fault detection device to achieve the purpose of timely maintenance.
