Abstract
A kind of modified model earth connection that can be used in conjunction with insulating bar, comprise insulating bar, copper bar, earth connection, earth connection arranges with insulating bar inner, the first head part of earth connection is connected with copper bar, on copper bar copper bar, there are three holes, wherein two corresponding apertures are corresponding with the hole of original the end of a thread, and another one is preformed hole.The utility model increases the safe distance between personnel and equipment in some type earth connection (as double-spring type) of seting out, and does not need ladder to assist to have reduced between operation reality, has improved operating efficiency.
Description
One, technical field
The utility model relates to transformer station, construction line ground connection field, is specially a kind of modified model earth connection that can be used in conjunction with insulating bar.
Two, background technology
Existing the earth connection of the dislodging types such as a large amount of double-spring types, during dislodging, need staff to assist with ladder, safe distance shortens, the operating time is long.
Three, summary of the invention
In order to overcome above defect, the utility model provides a kind of modified model earth connection that can be used in conjunction with insulating bar, and the action bars of earth connection is lengthened, and has increased safe distance when carrying out hanging earthing conductor operation, do not need ladder to assist, thereby reduced the operating time.
The technical scheme that the utility model is taked is: a kind of modified model earth connection that can be used in conjunction with insulating bar, comprise insulating bar, copper bar, earth connection, it is characterized in that: earth connection is arranged at insulating bar inside, the first head part of earth connection is connected with copper bar, on copper bar, there are three holes, wherein two corresponding apertures are corresponding with the hole of original the end of a thread, and another one is preformed hole.
Triangle is arranged in the position in three holes described in the utility model, and described preformed hole stretches out outside insulating bar.
The utility model fritter copper bar that superposes on the basis of original the end of a thread, has three holes, Liang Ge hole, one end (corresponding aperture) corresponding with the hole of original the end of a thread (diameter, position) on copper bar, the other end is preformed hole, preformed hole diameter is at 10mm,, be applicable to the insulating bar of different electric pressures.Two corresponding apertures with the end of a thread and copper bar one end in original screw crimping, penetrate insulating bar in the preformed hole of the other end in use, can realize and being used in conjunction with of insulating bar the earth connection of seting out operation.
The beneficial effects of the utility model are: the utility model increases the safe distance between personnel and equipment in some type earth connection (as double-spring type) of seting out, and do not need ladder to assist to have reduced between operation reality, have improved operating efficiency.
Four, accompanying drawing explanation
Fig. 1 is a kind of modified model ground line configuration schematic diagram that can be used in conjunction with insulating bar of the utility model.
Five, embodiment
A kind of modified model earth connection that can be used in conjunction with insulating bar, comprise insulating bar 4, copper bar 1, earth connection 3, earth connection 3 is arranged at insulating bar 4 inside, the first head part of earth connection 3 is connected with copper bar 1, on copper bar 1, there are three holes, wherein two corresponding apertures are corresponding with the hole of original the end of a thread 2, and another one is preformed hole.
Triangle is arranged in the position in three holes described in the utility model, and described preformed hole stretches out outside insulating bar 4.
The utility model fritter copper bar that superposes on the basis of original the end of a thread, has three holes, Liang Ge hole, one end (corresponding aperture) corresponding with the hole of original the end of a thread (diameter, position) on copper bar, the other end is preformed hole, preformed hole diameter is at 10mm,, be applicable to the insulating bar of different electric pressures.Two corresponding apertures with the end of a thread and copper bar one end in original screw crimping, penetrate insulating bar in the preformed hole of the other end in use, can realize and being used in conjunction with of insulating bar the earth connection of seting out operation.
The beneficial effects of the utility model are: the utility model increases the safe distance between personnel and equipment in some type earth connection (as double-spring type) of seting out, and do not need ladder to assist to have reduced between operation reality, have improved operating efficiency.
