Device and method for entering equipotential area of alternating-current extra-high-voltage composite cross arm line in charged mode

Abstract

The invention relates to a device and a method for entering an equipotential area of an alternating-current extra-high-voltage composite cross arm line in a charged mode. The device comprises an auxiliary carrying tool and an insulating operating rod, wherein the auxiliary carrying tool is installed on a composite cross arm and ridden by an equipotential operator; the auxiliary carrying tool is provided with rolling wheels for rolling along the axis of the composite cross arm; a pushing hanging point on the auxiliary carrying tool is connected with the insulating operating rod; and a ground potential operator pushes the auxiliary carrying tool by using the insulating operating rod to push the equipotential operator to a to-be-operated phase conductor position so as to enter the equipotential area. According to the device and method for entering the equipotential area of the alternating-current extra-high-voltage composite cross arm line in the charged mode, the charged operator of the alternating-current extra-high-voltage composite cross arm line has very high safety and convenience in the process of entering the equipotential area; the safety of charged operation of the alternating-current extra-high-voltage composite cross arm line is guaranteed; and the safety and stability of the alternating-current extra-high-voltage composite cross arm line are improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission, and more specifically, relates to a device and method for carrying electricity into an AC ultra-high voltage composite cross-arm line for equal potential. Background technique [0002] Due to the advantages of light weight, high strength, corrosion resistance, easy processing, designability and good insulation performance, composite materials are one of the ideal materials for building transmission tower structures. Composite material towers have the advantages of saving steel, reducing the size of the tower head and the width of the corridor; its structure is light, easy to process and shape, and the cost of transportation and assembly is low; The maintenance cost is low; the "environmental friendliness" of the line is enhanced due to the adjustable color of the pole tower, non-toxicity, and reusability after scrapping. Composite material towers have obvious effects in t...

Problems solved by technology

As a new type of line structure, the AC UHV composite cross-arm line (the arrangement of the wires is as follows: figure 1 ), the tower structure type and wire layout are different from conventional AC UHV lines. Since there is no conventional tower crossarm, it is impossible to provide hanging points for conventional vehicles, and it is impossible to use hanging basket method, soft ladder method, etc. to enter and exit the equipotential
