Description

Carry a reel short circuit ground wire

technical field

The utility model relates to an electric safety tool, in particular to a winding coil short-circuit grounding wire.

Background technique

Because the portable short-circuit grounding wire is used in the daily high-voltage outdoor storage process, three grounding rods, grounding steel brazing and grounding wires are used as a group. Since the wires are too long to tens of meters, the short-circuiting grounding wires are self-winding together, so , It is extremely inconvenient to use and collect. In the long-term use process, the grounding wires often have knots, dead knots, broken strands, broken strands, and protective insulation aging. The inspection cycle is five years, so some short-circuit grounding wires have serious defects and serious damages before they reach the service life. According to the overhaul and maintenance personnel of the outdoor high-altitude operation line, it is time-consuming and laborious to hang and remove the grounding wire every time the safety measures are taken, and the operation is clumsy.

As a safety tool tester, during the routine safety tool test, it was also found that in addition to the above-mentioned defects in the portable short-circuit grounding wire, there is also a direct broken strand at the crimping point between the wiring nose and the flexible wire; due to long-term folding and three-phase The short contact points are not crimped with copper sleeves, and the connecting lug and ground rod hooks do not use copper nuts, but use the original iron nuts. The conductive resistance of the iron nuts does not meet the standard after corrosion.

Therefore, there is a need for a portable short-circuit grounding wire that is convenient, efficient and reasonable during operation and use.
