Description

Grounding wire winder

Technical Field

The utility model relates to an electric power construction appurtenance field, more specifically relates to an earth connection spooler.

Background

The substation often needs to use a temporary grounding wire during daily electrical operation, such as switching operation to overhaul equipment. The grounding measure is mainly completed by an insulating rod and a grounding wire. The ground wire generally needs to be wound around an insulating rod. The worker winds the ground wire around the insulating rod, moves the ground wire to the site, and releases the ground wire wound in the insulating rod at specific intervals to perform related electrical operation. In the process of electrical production operation, the winding and the storage of earth connection consume physical power very much. Particularly, the sizes of the grounding wires with different voltage grades are completely different, the higher the voltage grade is, the larger the sizes of the insulating rod and the grounding wire are, and the overall weight is increased, so that the insulating rod is held by one person and the manual winding is carried out by one person under the general condition, and the larger problem is brought to the winding and unwinding work of the grounding wire.
