Description
Technical field
The utility model relates to power engineering field, particularly, relates to a kind of bus bar earthing device.
Background technology
Bus bar earthing device is exactly as 110kV and following transformer interruption maintenance, carries out short circuit grounding to the mesolow side using bus bar to connect.According to " managing security tools and instruments testing regulations " requirement, the power frequency withstand test of earth connection D.C. resistance and hook stick in groups carries out a periodic inspection in every 5 years.
The mesolow side of 110kV and following transformer all uses bus bar connection to be connected with switch cubicle, bus bar uses double-deck 125mm, double-deck 100mm or three layer 100mm electric conducting material, distance more than 4 meters, ground, using conventional earthing device at present always, there is following defect in existing bus bar earthing device, on the one hand little not easy to operate, the contact area that can not ensure grounded part and conductor of wire clamp opening.Two is that distance ground is high, and personnel need go up framework and carry out installing and removing, and security risk is large.Three is that the operating time is long, and efficiency is low.
Utility model content
The purpose of this utility model is, for the problems referred to above, proposes a kind of bus bar earthing device, to realize the effective contact area ensureing grounded part and conductor, reduces security risk, and the advantage of increasing work efficiency.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of bus bar earthing device, comprise insulating bar, wire clamp, tongue piece, tongue piece controller and adjuster valve, described insulating bar penetrates wire clamp, and the top of insulating bar arranges adjuster valve, this adjuster valve is arranged in wire clamp, described tongue piece is arranged on the upper end of wire clamp two frame, and the junction of tongue piece and wire clamp frame arranges tongue piece controller.
Further, also comprise short-circuit line, earth connection, earth terminal and the folder that confluxes, the bottom of described wire clamp connects short-circuit line, and this short-circuit line is connected to wire clamp and confluxes between folder, and the folder that confluxes is connected with earth terminal by earth connection.
Further, the A/F of described wire clamp is equal with the width of bus bar.
Further, the A/F of described wire clamp is 125mm or 100mm.
Further, described wire clamp adopts aluminium alloy compression casting to form.
The technical solution of the utility model has following beneficial effect:
The technical solution of the utility model, is equipped with movable tongue piece in wire clamp open upper end, and personnel stand in ground direct control, when wire clamp opening rises to the top of bus bar, tongue piece falls automatically, is stuck in the top of bus bar, by rotating insulated action bars, make wire clamp stuck on bus bar, thus ensure that effective contact area of grounded part and conductor, personnel stand in the enterprising luggage in ground and establish and remove, and have evaded security risk, substantially reduce the operating time, improve inefficiency.And wire clamp opening and the wide effective contact area further ensuring grounded part and conductor of bus bar.
Accompanying drawing explanation
Fig. 1 is the bus bar earthing device use reference configuration schematic diagram described in the utility model embodiment.
By reference to the accompanying drawings, in the utility model embodiment, Reference numeral is as follows:
1-wire clamp; 2-adjuster valve; 3-insulating bar; 4-tongue piece; 5-tongue piece controller; 6-short-circuit line; 7-confluxes folder; 8-earth connection; 9-earth terminal.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of bus bar earthing device, comprise insulating bar 3, wire clamp 1, tongue piece 4, tongue piece controller 5 and adjuster valve 2, insulating bar 3 penetrates wire clamp 1, and the top of insulating bar 3 arranges adjuster valve 2, this adjuster valve 2 is arranged in wire clamp 1, and tongue piece 4 is arranged on the upper end of wire clamp two frame, and tongue piece 4 arranges tongue piece controller 5 with the junction of wire clamp frame.Also comprise short-circuit line 6, earth connection 8, earth terminal 9 and the folder 7 that confluxes, the bottom of wire clamp 1 connects short-circuit line 6, and this short-circuit line is connected to wire clamp 1 and confluxes between folder 7, and the folder 7 that confluxes is connected with earth terminal 9 by earth connection 8.
Wherein, the A/F of wire clamp is equal with the width of bus bar.Can be 125mm or 100mm according to the A/F that the width wires of bus bar presss from both sides.Wire clamp adopts aluminium alloy compression casting to form.
After identification is grounded the true no-voltage of equipment three-phase, earth terminal is loaded onto at earth point, with insulating bar phase-splitting, wire clamp is connected with electric conductor, when wire clamp opening rises to the top of bus bar, tongue piece controller down moves under bus bar Action of Gravity Field, thus drives tongue piece automatically to fall, be stuck in the top of bus bar, regulate the distance between tongue piece and adjuster valve by rotating insulated action bars, make wire clamp stuck on bus bar, dismounting order in contrast.Aforesaid operations personnel all stand in ground and directly carry out, and complete earth connection installing easily and remove.
Wire clamp is upper shed, and technique is exquisite, structure is dexterous.By insulating bar, form with the wide wire clamp of bus bar, tongue piece, tongue piece controller, adjuster valve, short-circuit line, earth connection, earth terminal, the folder that confluxes, they are installed in insulating bar.With existing earth connection maximum unlike: devise the aluminium alloy compression casting wire clamp wide with bus bar, it there are movable tongue piece and tongue piece controller, two tongue pieces are vertical parallel at ordinary times, when installing earth connection, when wire clamp rises to certain altitude, under the effect of tongue piece controller, two tongue pieces bend 90 degree, be stuck in the top of bus bar, in same level, the distance between tongue piece and adjuster valve is regulated by rotating insulated action bars, make wire clamp stuck on bus bar, reliable ground.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
