Description

Operating rod for quickly dismounting temporary short circuit grounding wire

Technical Field

The utility model relates to a portable type temporary short circuit link articulates or dismantles high-pressure earth connection's device specifically is a quick assembly disassembly temporary short circuit earth connection's action bars.

Background

The grounding wire is a wire directly connected with the ground and can also be called a safe return line, and the grounding wire directly transfers high voltage to the ground in danger to be a life line.

The temporary short circuit of the grounding wire in the power system is an important protection tool for ensuring the safety of workers when voltage unexpectedly appears on the power-off equipment and lines. The grounding wire is a necessary device for grounding transformer equipment and wires, ensuring the personal safety of electric power operation and maintenance personnel and ensuring the safety of a power grid and equipment, however, the installation and the disassembly of the grounding wire are electrical operations with higher danger, large volume labor intensity and large time consumption, and if an accident occurs, the personal safety of personnel, the normal operation of equipment and the stable operation of the power grid are seriously damaged. In recent years, failure accidents of the assembly and disassembly of grounding wires of transformer substations occur frequently, and how to improve the assembly and disassembly safety, strengthen the connection stability and improve the operation timeliness becomes an urgent subject.

The rectangular busbar on the secondary side of a transformer in a general transformer substation is usually hung with a grounding wire in a spiral compression mode, the grounding wire controls a grounding wire clamp through a bolt with an adjustable stroke in the wire clamp, and a lead screw fixed with an insulating operating rod needs to be manually rotated to control the tightness of the wire clamp to be connected with the busbar. It basically comprises an adjusting seat, a screw rod, an insulating operating rod and the like. In actual operation, bolt tightening operation needs to be performed in a circle, which is very troublesome, not only affects power failure rush-repair time, but also has the risk of damaging the stability of a power system; moreover, an operator needs to fix the operating rod and rotate the bolt at the same time, which often causes that the operating space is not allowed, the clamping position of the grounding wire is not tight or staggered, the connection is easy to be unreliable, and the risk of virtual connection of the grounding wire is increased; in addition, in order to confirm the loading and unloading condition of the grounding wire, the staff with an improper operating handle cannot consciously cross the safety distance on the operating rod, and the safety of the staff is threatened. The manual rotation of the bolt causes time and labor consumption in assembling and disassembling work, and the operation safety can not be guaranteed, so the prior grounding wire operating rod needs to be improved to shorten the time for assembling and disassembling the grounding wire and increase the connection reliability and stability of the grounding wire.

Currently, there is a patent product ZL 201621219821.5 "a screw-in type ground clip" which is an improvement on the above products. The product is not additionally provided with electric power and a motor, and is provided with a remote controller and the like, and although the operation is upgraded from manual operation to electric operation, the actual using effect is not good. The defects are as follows: 1. the structure is complicated, the product is heavy, and the manufacturing cost is high; 2. once the motor is damaged or no power is supplied, the use is too strenuous, and the efficiency is not only low but also greatly reduced.
