Electro-hydraulic servo follow-up system for long-span transmission line conductor and ground wire release

Abstract

The invention relates to an electro-hydraulic servo follow-up system for paying off long-span electric transmission line ground wires. The system is characterized by comprising a measurement tracking system, a main control system, a pitching following control system, an orientation following control system and an electro-hydraulic paying-off actuating system which are arranged on a vehicle-mounted mechanical system, wherein the measurement tracking system, the pitching following control system, the orientation following control system and the electro-hydraulic paying-off actuating system are all electrically connected with the main control system. The electro-hydraulic servo follow-up system has the advantages as follows: the target tracking, the orientation control and the angle control can be realized; the vehicle-mounted launch is realized, and the construction transportation is convenient; an electro-hydraulic control system is used for performing push shot control, the controllability is high, ignition is not required, and accidents are avoided; the catapulting distance of an actuating guide body is long, and the controllable voyage can reach 200 km; construction barriers in an electric transmission line corridor are not required to be cleared away, and the environment is protected; the system can cross a river, a lake and a bay for paying off the wires, and closure of navigation is not required; and the wires can be prevented from being abraded, the construction efficiency is improved, and the system is reasonable in structure, easy to operate, high in reliability and good in safety.

Description

technical field [0001] The invention relates to the technical field of laying-out construction of conductor ground wires of large-span transmission lines. In particular, it relates to an electro-hydraulic servo follow-up system for a long-span transmission line conductor and ground wire release. Background technique [0002] The transmission line is the main artery of the power system and an important lifeline project related to the national economy and the people's livelihood. With the rapid development of my country's economy, the demand for electricity in various industries has soared, which has made the voltage level of the transmission line higher and higher, and the distance is larger. The weight of the line is getting heavier, especially in the construction of UHV transmission lines in recent years. When the line crosses the river, due to the large crossing length, the existing setting-out construction method cannot meet the actual needs of the project, affecting the s...

Problems solved by technology

Using hydrogen balloons to release wires needs to close the channel, which has a great impact on the local aerial bomb transportation; using rockets to release wires has poor accuracy, does not have the ability to track targets, has large deviations, and is very poor in safety; Helicopter setting-out is limited by weather conditions, and the high-altitude operation of the helicopter hanging the ground wire is very easy to cause accidents and the construction cost is high
