Abstract

The invention provides a biological theft-proof sensor for a transmission line. The sensor comprises an inductive lead wire, a controllable oscillation signal generation circuit and a singlechip detection, signal processing and sensitivity arrangement circuit which are connected in turn, wherein the controllable oscillation signal generation circuit and the singlechip detection, signal processingand sensitivity arrangement circuit are connected with a power supply source respectively. The theft-proof sensor is used for a theft-proof monitoring system of an overhead transmission line, can be induced in time when a stayed tower of the transmission line is stolen, and improves the accuracy and reliability of the theft-proof monitoring system.

Description

technical field [0001] The invention belongs to the technical field of sensor equipment manufacturing, and relates to a sensor, in particular to a biological anti-theft sensor for a power transmission line. Background technique [0002] In the power transmission system, especially in the remote mountainous areas, the theft of the tower cables and transmission wires of overhead transmission lines occurs frequently, which brings great hidden dangers to the safe and reliable operation of the transmission grid. At the same time, power outages caused by theft , resulting in significant economic losses. Therefore, it is of great significance to design an anti-theft monitoring system that can report to the relevant personnel in time when the transmission line is stolen. In this anti-theft monitoring system, the sensor used to monitor the intruder is very important. It directly affects the accuracy and reliability of the anti-theft monitoring system.
