Intelligent transmission line ice layer reduction system

Abstract

The present invention relates to an intelligent transmission line ice layer reduction system which comprises a simulated conductive wire, a capacitive sensing type ice layer sensor and a robot walking mechanism. The simulated conductive wire is at the positon of an iron tower where a transmission line is. The capacitive sensing type ice layer sensor is arranged on the simulated conductive wire and is used for detecting the real-time ice layer thickness of the simulated conductive wire. The robot walking mechanism is mounted on the transmission line, receives real-time ice layer thickness, and carries out ice cutting operation based on the real-time ice layer thickness. Through the system, the ice cutting strength of a robot can be controlled according to the actual ice layer thickness of the transmission line, and thus the effect of ice layer cutting is improved.

Problems solved by technology

[0003] The icing of the transmission line will cause the following hazards: (1) damage to the tower, if the line is too thick with ice, it will cause the mechanical load of the tower to be overloaded and break; When the ice falls off first (the ice coating on the conductors does not necessarily fall off at the same time), the conductors will rise rapidly or jump up and down, causing a phase-to-phase short circuit, tripping the line switch, and interrupting the power supply; When the ice thickness in each span of the line is uneven, the conductor sag will change greatly, causing the hanging insulator string to tilt, and the fittings bear a large horizontal force. In the span with too thick ice, it will cause Grounding accidents occur due to severe sagging of wires; (4) After the insulator strings are covered with ice, the insulation performance will be greatly reduced. When the ice-covered insulator strings are suspended and melted, icicles may be formed, which will short-circuit the insulator strings and cause grounding accidents

[0004] In the prior art, the technical solution for deicing transmission lines still mainly relies on on-site manual operations, that is, arranging employees of the local power supply management department to carry deicing tools to carry out on-site deicing of transmission lines within the jurisdiction. Although this method can achieve Deicing effect, but the mode of artificial deicing inherently has the disadvantages of low deicing efficiency, time-consuming and labor-intensive. At the same time, if there is a little carelessness, the deicing personnel may fall from a high place or be hit by the high voltage of the power transmission line, causing serious damage to the environment. Deicing personnel will cause serious personal injury, and will also cause certain damage to power supply equipment

[0005] In the prior art, some remote control schemes for robot deicing have also appeared. However, due to the excessive equipment and complex structure of the transmission grid, the environment of the transmission line is generally relatively harsh, and the structural design of the robot itself is unreasonable, resulting in the existing technology. The robot deicing solution is difficult to apply in large quantities and can only stay in the laboratory stage; more importantly, the lack of on-site electronic ice layer measurement equipment leads to poor deicing effect
