Abstract

The invention relates to an intelligent detection robot for a positive and negative 800-kilovolt high-voltage direct-current transmission line insulator. The intelligent detection robot comprises a plurality of main guide rods and a main bracket, wherein the main bracket is foldable along the circumferential direction and can be sleeved on an insulator string; the main guide rods are located on the inner side of the main bracket and are connected with the main bracket; at least one walking arm which is capable of rotating and driving the intelligent detection robot for the positive and negative 800-kilovolt high-voltage direct-current transmission line insulator to move along an axial direction of the insulator string is connected with one side of the main bracket; a detection control unit capable of controlling the motion state of the walking arm and detecting the performance of the insulator string is also arranged on the main bracket. The intelligent detection robot for the positive and negative 800-kilovolt high-voltage direct-current transmission line insulator has a simple structure, is stable and reliable, is capable of increasing the detection efficiency of the insulator string and is capable of reducing the danger of aloft work.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission, in particular to an intelligent detection robot for insulators of plus or minus 800 kilovolt UHV DC transmission lines. Background technique [0002] Insulators are used to support and fix live conductors, and to insulate a sufficient distance between live conductors or between conductors and the earth. Insulators should have sufficient electrical insulation strength and moisture resistance. In the operation of the power system, it works in a complex and harsh environment composed of strong electric field, mechanical stress, pollution, temperature and humidity for a long time. The probability of failure is very high, which seriously threatens the safe operation of the power system. At present, the insulators used in UHV (UHV refers to the voltage level of ±800kV and above DC and 1000kV and above AC) DC transmission lines mainly include silicone rubber composite insulators...
