High-voltage transmission line on-line monitoring method

Abstract

The invention relates to an online monitoring method for a high-voltage transmission line; the method comprises the steps: a CT energy-taking module is mounted on a lead body, then the lead CT energy-taking module is connected to a high-voltage side voltage-stabilizing energy-storing module disposed in a high-voltage side grading ring, and stable DC electric energy outwards is supplied, namely, supplying energy to a high-voltage side; then direct-current electric energy output by high-voltage side energy supply drives a constant-current source module, the constant-current source module drives a solid laser to generate energy laser with fixed wavelength, the energy laser is coupled to an energy transmission optical fiber in a composite insulator core column, and the energy laser is transmitted to an iron tower side, namely, a photoelectric energy converter in a low-voltage side grading ring through the energy transmission optical fiber so as to supply energy to the low-voltage side; the single-chip microcomputer transmits information obtained from the monitoring modules to the Internet cloud platform through the 5G communication module, and receives a control instruction issued by the Internet cloud platform. The method provided by the invention has the characteristics of stable and reliable energy supply and long service life, and can meet the continuous energy supply demand of high-power online monitoring equipment.

Description

technical field [0001] The invention belongs to the field of on-line monitoring of high-voltage transmission lines, and relates to a technology for monitoring the operation of high-voltage transmission line equipment, in particular to a method for on-line monitoring of high-voltage transmission lines. Background technique [0002] With the advancement of the construction of smart transmission lines, a large number of wireless monitoring equipment has been added to the transmission lines and iron towers. However, the current online monitoring equipment is of different types and different manufacturers. Moreover, due to the high voltage between the transmission line and the iron tower, it is difficult to realize the integrated arrangement of the monitoring terminals on both sides of the insulator. [0003] However, most of the monitoring equipment on the current transmission tower is powered by solar panels, batteries, and micro fans. The power supply of solar energy and micr...
