Transmission line unmanned aerial vehicle and electric lifting device combined live working method

Abstract

The present invention belongs to the technical field of electric lifting machine and live line operation and particularly relates to a transmission line unmanned aerial vehicle and electric lifting device combined live working method. An unmanned aerial vehicle is used to suspend an insulation rope to a conductive wire, a semi-static rope is dragged through the insulation rope to suspend the semi-static rope to the conductive wire, an equipotential electrician operates a small fly people machine to enter a strong electric field and reach a live line to carry out defective elimination operation. The method comprises the steps of setting the unmanned aerial vehicle and the insulation rope, checking the unmanned aerial vehicle, throwing the rope through the unmanned aerial vehicle, dragging the semi-static rope, installing the semi-static rope, installing the small fly people machine and a buffer self-locking device, carrying out equipotential electrician checking and connection, lifting the equipotential electrician by the small fly people machine and completing potential transfer, hanging a hard insulation ladder head and carrying out translocation, entering into equipotential to hang an extension rope to eliminate a defect, and exiting the equipotential. An operator is lifting by using the small fly people machine to reach a live line defective position, climbing an iron tower and a soft ladder to enter and leave the strong electric field is not needed, the safety risk is small, the working efficiency is high, and the operation is simple.

Description

technical field [0001] The invention belongs to the application of unmanned aerial vehicles and electric elevators in the technical field of live line operation, and relates to a method for combined live operation of electric transmission line unmanned aerial vehicles and electric lifting devices. Background technique [0002] With the vigorous development of ultra-high voltage power grids, the improvement of power supply reliability, the continuous increase in the number of kilometers of maintenance lines per capita, and the continuous increase in the workload of operators, power outages caused by defects in ultra-high voltage transmission lines are not only huge economic losses , and has great political influence. Ultra-UHV lines have the characteristics of high voltage, strong electric field, high iron tower, large span, large mechanical load on components, large structure and heavy weight of fittings and insulators, etc., which brings a series of operational difficulties...

AI Technical Summary

Problems solved by technology

[0004] China's aviation control should be the most stringent country in the world. If you have to go through many cumbersome procedures such as applying for routes every time you carry out live work, you will definitely miss the best time to eliminate defects. The investment is huge every time, and the practicability in our country is not strong

[0005] According to the requirements of use, the main problem and difficulty in the equipotential live work is the process of entering and exiting the electric field. Taking the traditional two-short three-way method to enter and exit the strong electric field of ±800kV transmission lines as an example, the insulator low zero value detection is required before entering the electric field, only to detect this One item requires 3 people to operate at the same time, and it takes about 30 minutes. If the number of low-zero insulators reaches the specified value, it will not be possible to carry out live work

To enter the electric field across the second short and third, it is necessary to pass through the 15.36-30.24m long insulator string. The physical strength of the equipotential electrician has been exhausted. The physical fitness requirements are extremely high, and the working conditions are relatively restrictive

[0006] Up to now, there is no method and tool for entering and exiting strong electric fields with high efficiency, strong versatility, and capable of carrying out various types of operations in our country.
