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

Ring main unit earthing tool
Technical field
The present invention relates to a kind of ring main unit earthing tool.
Background technology
In recent years, development along with city, each big city 10 kilovolt change cable laying into by overhead transmission line, circuit breaker becomes ring main unit from fall insurance, to urban beautification, added beautiful scenery one, same at operation power personnel maintenance cable, if when running into ring main unit and stopping power transmission, need to disconnect indivedual intervals, then for off interval installing earth electrode, after installing earth electrode, earth rod is vertical with ring main unit, cause earth rod most of exposed in ring main unit outside, ring main unit door can not be closed, but now all the other intervals are all charged, therefore can directly threaten like this operation power personnel and the personnel's that pass by one's way safety.
Summary of the invention
The object of this invention is to provide a kind of ring main unit earthing tool, can when ring main unit indivedual intervals power failure ground connection, normally close ring main unit door, thereby improve operation power personnel and the personnel's that pass by one's way fail safe.
An earthing tool, its special feature is: comprise insulating bar, one end of this insulating bar and earth electrode head are hinged.
One end of described insulating bar is connected with earth electrode head by universal joint, thereby makes can relatively rotate between insulating bar and earth electrode head.
One end of described insulating bar is installed with U-shaped plate, two ends relative on this U-shaped plate all have installing hole, also comprise rotating shaft, this rotating shaft is vertically passed from one end of described earth electrode head and the two ends of this rotating shaft are arranged on respectively aforesaid two installing holes, between this rotating shaft and earth electrode head, be matched in clearance, thereby make can relatively rotate between insulating bar and earth electrode head.
Through probationary certificate, adopt after earthing tool of the present invention, can thereby grounded part is crooked substantially parallel with ring main unit door after installing earth electrode, thus when guaranteeing ground connection, can normally close ring main unit door, thus guaranteed operation power personnel and the personnel's that pass by one's way safety.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention is a kind of ring main unit earthing tool, comprises insulating bar 2, and one end of this insulating bar 2 and earth electrode head 1 are hinged.And the other end of this insulating bar 2 is provided with rubber sleeve or sponges cover, thereby while avoiding insulating bar 2 to rotate, damage ring main unit inside.The one end that can be specifically insulating bar 2 is connected with earth electrode head 1 by universal joint, thereby makes can relatively rotate between insulating bar 2 and earth electrode head 1.
Or one end of insulating bar 2 is installed with U-shaped plate 3, installation position is the arc junction of U-shaped plate 3 bottoms.On this U-shaped plate 3, the two ends of relative opening part all have installing hole, also comprise rotating shaft, this rotating shaft is vertically passed from one end of described earth electrode head 1 and the two ends of this rotating shaft are arranged on respectively aforesaid two installing holes, and between this rotating shaft and earth electrode head 1, be matched in clearance, thereby make can relatively rotate between insulating bar 2 and earth electrode head 1.
First that 1 alignment of the earth electrode head of insulating bar 2 and copper material is into a line during use, then earth electrode head 1 is arranged on to the ground connection place of the off interval of ring main unit, connect after earth connection again and to be 90 ° of angles with earth electrode head 1 and can to keep parallel with ring main unit door insulating bar 2 is crooked, thereby no longer affect closing of cabinet door.

Claims (3)

1. a ring main unit earthing tool, is characterized in that: comprise insulating bar (2), one end of this insulating bar (2) and earth electrode head (1) are hinged.
2. ring main unit earthing tool as claimed in claim 1, is characterized in that: one end of described insulating bar (2) is connected with earth electrode head (1) by universal joint, thereby makes can relatively rotate between insulating bar (2) and earth electrode head (1).
3. ring main unit earthing tool as claimed in claim 1, it is characterized in that: one end of described insulating bar (2) is installed with U-shaped plate (3), at the upper relative two ends of this U-shaped plate (3), all have installing hole, also comprise rotating shaft, this rotating shaft is vertically passed from one end of described earth electrode head (1) and the two ends of this rotating shaft are arranged on respectively aforesaid two installing holes, between this rotating shaft and earth electrode head (1), be matched in clearance, thereby make can relatively rotate between insulating bar (2) and earth electrode head (1).
