Abstract
The utility model relates to a ring main unit grounding tool. The ring main unit grounding tool is characterized in that the ring main unit grounding tool comprises an insulation operating lever (2); one end of the insulation operating lever (2) is hinged to a grounding body head (1); one end of the insulation operating lever (2) is fixedly provided with a U-type plate (3); two opposite ends of the U-type plate (3) are both provided with installation holes; the ring main unit grounding tool also comprises a rotating shaft; the rotating shaft vertically passes through one end of the grounding body head (1); two ends of the rotating shaft are respectively installed in the abovementioned installation holes; and the rotating shaft is in clearance fit with the grounding body head (1), so that the insulation operating lever (2) and the grounding body head (1) can rotate relatively. The ring main unit grounding tool is proved on trial that after a grounding body is installed, a grounding part can be bent to be parallel to a ring main unit door, and thus grounding is ensured while the ring main unit is normally closed, thereby guaranteeing safety of electrical operators and passers-by.
Description
Technical field
The utility model relates to a kind of ring main unit earthing tool.
Background technology
In recent years, along with the development in city, each big city 10 kilovolt change cable laying into by overhead transmission line, circuit breaker becomes ring main unit from fall insurance, add beautiful scenery one to urban beautification, 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.
Utility model content
The purpose of this utility model is to provide a kind of ring main unit earthing tool, can in the time of 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.
A kind of ring main unit 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 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 installing hole, between this rotating shaft and earth electrode head, be matched in clearance, thereby make can relatively rotate between insulating bar and earth electrode head.
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.
Through probationary certificate, adopt after earthing tool of the present utility model, thereby can be by bending grounded part substantially parallel with ring main unit door after installing earth electrode, thus in guaranteeing ground connection, can normally close ring main unit door, thus guarantee 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 utility model.
Embodiment
As shown in Figure 1, the utility model 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.
When use, first the earth electrode head 1 of insulating bar 2 and copper material is alignd into a line, 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 bending insulating bar 2, thereby no longer affect closing of cabinet door.
Claims (2)
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;
One end of described insulating bar (2) is installed with U-shaped plate (3), all have installing hole at the upper relative two ends of this U-shaped plate (3), 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 installing hole, 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).
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).
