Overhead transmission line ground wire on-line energy-taking power supply system

Abstract

The invention provides an overhead transmission line ground wire on-line energy taking power supply system. The system comprises an energy taking module, a lightning protection module, a rectification and voltage stabilization module, an energy storage module and a control communication module which are arranged on a ground wire, wherein the output end of the energy taking module is connected with the input end of the lightning protection module, and the output end of the lightning protection module is connected with the output end of the rectification and voltage stabilization module; the second output end of the rectification and voltage stabilization module supplies power to a load, the first output end of the rectification and voltage stabilization module is connected with the input end of the energy storage module, and the output end of the energy storage module is connected to the second input end of the rectification and voltage stabilization module; and the control communication module receives a monitoring signal output by the rectification and voltage stabilization module and outputs a control command to the control end of the rectification and voltage stabilization module and the control end of the energy taking module, and the control communication module is in communication connection with a remote server. Power can be stably and reliably taken from the bottom line of the overhead line and supplied to ground wire monitoring equipment for use, and the continuity and stability of power supply can be ensured, so that the working stability of the ground wire monitoring equipment can be effectively ensured.

Description

technical field [0001] The invention relates to an on-line power supply system, in particular to an on-line energy-taking power supply system from ground wires of overhead power transmission lines. Background technique [0002] There are many on-line monitoring devices in overhead transmission lines, therefore, how to supply power to the on-line monitoring devices has become a technical difficulty. [0003] In traditional technologies, storage batteries, wind power, and solar power are used. These power supply technologies generally have the following problems: battery power supply has a short service life, requires frequent maintenance, wind power and solar power supply have poor stability, and are expensive to use. Although there is currently an online power extraction system for overhead transmission lines, it is difficult to apply the existing power acquisition device for overhead wires to the ground wire monitoring device for overhead lines. Therefore, in order to solve...
