In the daily work of the transformer substation, the portable short-circuit grounding wire is frequently used. The hanging ground wire can effectively prevent sudden incoming calls of equipment and lines, prevent the induction voltage generated by the near-charged body, and guarantee the working safety of maintainers.

Because the grounding wire uses a thicker annealed copper wire and is relatively heavier, a part of physical strength of personnel is consumed when the grounding wire is supported by the grounding rod for a long time, and particularly the grounding wire needs to be hung by climbing at times and is very dangerous and inconvenient, so that the time for hanging the grounding wire can be reduced by improving a grounding wire device, and the physical strength consumption of the personnel is reduced.

The types of high-voltage short-circuit grounding wires currently used include flat-opening spiral high-voltage grounding wires, round-opening spiral high-voltage grounding wires, double-reed bayonet high-voltage grounding wires and the like. When the spiral high-voltage grounding wire is used, the grounding wire is fixed by rotating the grounding rod, the operation is very laborious, and the operating head is easy to shift and fall off in the rotating process. Two spring buckle formula high pressure earth connection can only hang on the wire, and can not use to the condition that will hang broad positions such as metal connecting piece, does not have universal applicability, consequently through designing a novel hand propelled high pressure short circuit earth connection, optimizes the operating means who articulates the earth connection, makes operation simpler, labour saving and time saving, hangs more stably, is difficult for droing, and application scope is wider simultaneously, uses under being fit for multiple situation.
