Description

A 10kV Insulation Piercing Test Grounding Ring

technical field

The utility model relates to an electrical inspection and grounding device for electrical equipment, in particular to a 10kV insulation puncture electrical inspection grounding ring.

Background technique

In the current medium and low voltage lines of the urban distribution network (that is, the voltage level of 10kV and below), overhead insulated wires are generally used for laying, and when repairing lines or equipment, in order to ensure the safety of maintenance personnel, it is necessary to verify that the line is dead and then hang the grounding Protective wire, which requires that the grounding clamp and the wire must be in reliable contact when the grounding wire is hung, and the insulated wire cannot be hung, so the grounding ring for electric testing is used. For many years, before the inspection and maintenance of 10 kV distribution transformers, the exposed part of the traditional electrical inspection grounding ring is perpendicular to the position of the operator, and the operator needs to tilt a large angle on the pole. Electrical testing and grounding wires are labor-intensive and unreliable in safety.
