Digital monitoring apparatus for electricity transmission line

Abstract

The invention relates to a digital monitoring device for a transmission line, which mainly comprises a main case, a support, a wine speed sensor, a wind direction sensor, an environmental temperature sensor, an environmental humidity sensor, a wire cable temperature sensor, an arc-shaped support, a rotating wind cup, a wind vane, a GPRS mobile communication antenna, a camera mechanism, a solar panel, a storage battery, a screened circuit box, a circuit board, a computer processor, a printer and an information transmitter. The temperature, humidity, wind direction and wind speed information is acquired through all the sensors, the running conditions of the line are acquired through the camera mechanism, and the information acquired by the main case and the camera is transmitted through the GPRS mobile communication antenna and is transmitted to the ground-based computer processor for programmed operation and printing. The device integrates the informatization, the digitalization and the programming technologies into a whole, realizes the on-line, remote control and monitoring measurement in all weathers, is safe, stable, reliable, accurate and rapid and fills the blank of scientific research of the kind of technology.

Description

technical field [0001] The invention relates to a digital monitoring device for transmission lines, which belongs to the technical field of remote on-line monitoring equipment for overhead high-voltage transmission lines. Background technique [0002] Overhead high-voltage transmission lines are an important part of the power system. High-voltage transmission cables are metal devices. The quality of the quality, insufficient compression during installation and debugging, etc. will cause the resistance of the high-voltage cable core to increase. Trigger arc short circuit, or even burn out the equipment, expand the damage range of the transmission line, and reduce the service life, especially the dynamic and static contacts of the line with high transmission capacity, and the heating phenomenon of the main transformer cable is more serious, the failure rate is high, and accidents occur frequently ; Since the transmission line is a high-voltage live equipment, the hot spot is ...
