Description

Installation tool for electrical inspection grounding ring

technical field

The utility model relates to the field of electric power construction, in particular to an installation tool for an electric test grounding ring.

Background technique

At present, the phenomenon of insulation of overhead wires is relatively common. The staff install the grounding ring for electrical inspection (for example: puncture-type electrical inspection grounding ring, the puncture-type electrical inspection grounding ring can be installed on the wire without stripping the insulation layer of the wire. , and at the same time do not damage the conductor and can reach the required short-circuit current) method cannot meet the needs of accident repair and daily operation and maintenance work.

Ordinary workers need to do power outage work when maintaining the line, and then install the grounding ring for the power outage line by climbing the pole or standing on the lifting trolley. However, there are the following problems in this method of installing the grounding ring for electrical testing:

1. There are potential safety hazards. Even if the grounding ring is installed for power failure, when the line is not grounded, sometimes the power will be returned and induced, which will cause the staff to get an electric shock.

2. The waiting time for power outage is increased, which brings inconvenience to people's production and life. Since it is necessary to perform power outage operation on the line first, and then install the grounding ring for electrical inspection, it will affect the normal electricity consumption of residents and enterprises.
