Ultra high voltage power transmission and transformation equipment high-altitude grounding operating device

Abstract

The invention provides an ultra high voltage power transmission and transformation equipment high-altitude grounding operating device and relates to the technical field of auxiliary overhaul equipment. Through setting a mobile mechanism, step climbing can be realized through the mobile mechanism moving up and down, the good obstacle climbing ability is realized, the whole device is more convenient and rapid to move to reach the designated position rapidly, and movement is quite convenient; through setting a chain type lifting mechanism driven by a motor, the whole device is made to have a wide application scope, and more safety and reliability are realized; through setting a position adjusting mechanism, three-axial movement of the lifting mechanism and a grounding wire clamp is realized, clamping of the grounding wire clamp can be rapidly realized, during use, the grounding wire clamp can be carried to the work field for assembling, the whole operation scope is quite small, operation can be accomplished by a worker on the ground, the worker has no need to climb high, high safety of the use process is realized, time and force saving is realized, the device is quite convenient, safety of the worker is protected, operation can be accomplished through one person, and work efficiency is substantially improved.

Description

technical field [0001] The invention relates to the technical field of maintenance auxiliary equipment, in particular to a high-altitude grounding operation device for super- and extra-high voltage power transmission and transformation equipment. Background technique [0002] The transmission voltage is generally divided into high voltage, extra high voltage and ultra high voltage. Internationally, high voltage (HV) usually refers to the voltage of 35-220kV; extra high voltage (EHV) usually refers to the voltage of 330kV and above and below 1000kV; ultra high voltage (UHV) refers to the voltage of 1000kV and above. High-voltage direct current (HVDC) generally refers to DC transmission voltages of ±600kV and below, and voltages of ±800kV and above are called ultra-high voltage direct current transmission (UHVDC). EHV and UHV transmission technology has the characteristics of long distance, large capacity, low loss and economy, and can greatly improve the transmission capacit...

AI Technical Summary

Problems solved by technology

[0003] At present, portable short-circuit grounding wires or grounding wires are often used for ultra-high voltage and ultra-high voltage grounding wires. The connection is mainly through people climbing and connecting, and many people are required to participate. There are many inconveniences, and it is more dangerous. It needs a long ground soft copper wire, and it is not easy to store. In order to ensure the reliability and safety of the system operation, the development and improvement of a high-altitude grounding operation device for ultra-high voltage and ultra-high voltage power transmission and transformation equipment is increasing. urgent
