Abstract

The invention relates to the testing field of a power supply, particularly to an auxiliary power supply circuit, comprising a switching power chip, a DC (direct current)-DC module, a first voltage stabilization module, a second voltage stabilization module, a positive and negative voltage conversion module and an isolated voltage stabilization module, wherein the input end of the first voltage stabilization module is connected with a 48V input power supply and the output end thereof is connected with the switching power chip; the output end of the switching power chip is connected with the control end of the DC (direct current)-DC module; the input end of the DC (direct current)-DC module is connected with the 48V input power supply and the other end thereof is a DC output end; the DC output end is connected with the feedback end of the switching power chip by the isolated voltage stabilization module; the DC output end is further connected with the input end of the positive and negative voltage conversion module and the input end of the second voltage stabilization module respectively; in combination with the switching power chip, input 48V is output by respectively converting into 5V, 3,3V and 5V via the DC-DC module.

Description

technical field [0001] The invention relates to an obstacle-free passage for an auxiliary overhead ground line inspection robot to cross a straight pole. Background technique [0002] With the development of the national economy and the progress of the society, the safe operation of the power system is becoming more and more important. The high-voltage transmission line is the lifeblood of the power system, and its failure directly threatens the safe operation of the power system. Due to the distribution points of the transmission line, which are far away from towns and cities, the terrain is complex, and the wires are exposed in the wild, they have been exposed to wind and rain for a long time and are subject to continuous Mechanical tension, electrical flashing, and the effects of material aging can easily cause wear, broken strands, corrosion and other damage. If it is not repaired and replaced in time, it will easily cause serious accidents, resulting in large-scale powe...

Problems solved by technology

[0003] At present, robots have been widely used in the field of high-voltage transmission lines, especially the live line inspection of transmission lines. However, on the current overhead transmission lines in my country, the application of line robots was not considered at the beginning of the design of the linear pole tower, resulting in robots. Unable to pass directly, the robot must perform various obstacle-crossing actions when encountering the suspension clamp of the linear pole tower, which affects the online passing efficiency of the robot, and the safety factor is low, so it is inevitable to build a barrier-free passage for it
