Power transmission and distribution line maintenance grounding device

Abstract

The invention discloses a power transmission and distribution line maintenance grounding device. The device comprises an insulation operation rod, a grounding head detachably connected with the top of the insulation operation rod, a protection ring arranged at the bottom of the insulation operation rod and a grounding wire connected with the grounding head, wherein the insulating operating rod is provided with an insulating operating rod motor, the insulating operating rod is used for controlling a lower end of a grounding head to rotationally ascend or descend, assisting the grounding head to be in close contact with or separated from a maintenance wire and controlling a grounding wire motor to be powered on or powered off; grounding wire motors are respectively arranged in a plurality of branches of the grounding wire and are used for controlling a grounding end of the grounding wire to be connected or disconnected with the maintenance wire end; and a control module for controlling the insulating operation rod motor and the grounding wire motor is arranged on the retaining ring. According to the device, safety of maintainers can be greatly protected, and efficiency of assembling and disassembling the grounding wire is greatly simplified.

Description

technical field [0001] The invention relates to the field of electric technology, in particular to a maintenance grounding device for power transmission and distribution lines. Background technique [0002] In the prior art, the grounding wire needs to be installed during maintenance of the power transmission and distribution line to ensure the safety of maintenance personnel; the installation and disassembly of the grounding wire must use an insulating operating rod of the corresponding voltage level. Currently, the insulating operating rod and the grounding wire are connected As a whole, the commonly used operating heads on the market are mainly divided into double-tongue operating heads and spiral operating heads (flat mouth, monkey head). The double-tongue type is directly in close contact with the transmission and distribution lines during use; the screw operation type is firstly in contact with the transmission and distribution line with the operating head, and the gro...

AI Technical Summary

Problems solved by technology

The double-tongue type is directly in close contact with the transmission and distribution lines during use; the screw operation type is firstly in contact with the transmission and distribution line with the operating head, and the grounding head is in close contact with the transmission and distribution line by rotating the insulating operating rod; At present, the screw operating head is mainly used in the maintenance process of transmission and distribution lines; the human body cannot touch the grounding wire in the process of installing and disassembling the grounding wire. Injury to the human body, in addition, the above-mentioned processing process results in time-consuming and labor-intensive assembly and disassembly
