Grounding tool of ring network cabinet

Abstract

The invention relates to a grounding tool of a ring network cabinet. The grounding tool is characterized by comprising an insulating operating rod (2); one end of the insulating operating rod (2) and a grounding body head (1) are hinged together. After a trial, it is testified that the grounding part of the grounding tool can be bended to be basically parallel to a door of the ring network cabinet. In this way, grounding is ensured while the door of the ring network cabinet can be normally closed, and therefore the safety of power operation personnel and the safety of passers-by are guaranteed.

Description

technical field [0001] The invention relates to a grounding tool for a ring network cabinet. Background technique [0002] In recent years, with the development of cities, the 10 kV lines in major cities have changed from overhead lines to cable laying, and circuit breakers have changed from drop insurance to ring network cabinets, adding a beautiful landscape to the beautification of the city. The maintenance cable is the same. If the power supply of the ring network cabinet is cut off, it is necessary to disconnect individual intervals, and then install a grounding body for the power failure interval. After the grounding body is installed, the grounding rod is perpendicular to the ring network cabinet, resulting in most of the grounding rods being exposed. Outside the ring network cabinet, the door of the ring network cabinet cannot be closed, but at this time the rest of the intervals are charged, so this will directly threaten the safety of power operators and passers-by...

After the grounding body is installed, the grounding rod is perpendicular to the ring network cabinet, resulting in most of the grounding rods being exposed. Outside the ring network cabinet, the door of the ring network cabinet cannot be closed, but at this time the rest of the intervals are live, so this will directly threaten the safety of power operators and passers-by
