Abstract

The invention relates to the electrical technical field. An automatic underground power line fault positioning and warning system comprises at least three sensors for detecting the working state of an underground power line, wherein each sensor is a wireless passive sensor and is provided with a communication module, each communication module is provided with at least two different kinds of communication media and comprises an ultrasonic communication module with an ultrasonic signal as the communication medium and a radiocommunication module with a radio signal as the communication medium, each sensor is connected with a main unit server through the corresponding communication module, and feature data for identity recognition are arranged in each sensor. Due to the fact that each communication module is provided with different communication media for joint communication, the system is suitable for communication conditions in different environments and with different distances, signal transmission stability is improved, and normal signal transmission can still be guaranteed when any communication module breaks down. Furthermore, feature data for identity recognition are transmitted outside through the communication modules, so that positioning is facilitated.

Description

technical field [0001] The invention relates to a fault alarm system in the field of electric power technology, in particular to an automatic fault location alarm system for underground power lines. Background technique [0002] The underground power line is the lifeblood of the power system, and it bears the heavy responsibility of transmitting electric energy. With the increasing scale of the power system, the number of high-voltage, high-energy, and long-distance underground power transmission lines is increasing. Once the underground power line fails, it will affect the safe operation of the power system, industrial and agricultural production, and people's daily life. Therefore, it is very important to ensure the safe operation of underground power lines. [0003] The transmission paths of high-voltage and ultra-high-voltage underground power lines on the grid are very long, some as long as hundreds of kilometers, and some as long as thousands of kilometers. Its distr...
