Abstract
The utility model relates to a can prolong formula three -phase short circuit grounding. Its technical scheme is: including insulating bar, three -phase formula earth connection, copper connection lug, the screw, the nut, the quick change male joint, the quick change female joint, copper ground lead, the earthing for work utmost point, three insulating bar are connected to the one end of three -phase formula earth connection, copper connection lug is connected to the other end, in the parallelly connected copper quick change male joint of crimping in copper connection lug's top, the quick change male joint is through being connected copper ground lead with quick change female joint cooperation, copper connection lug is connected to copper ground lead's the other end, copper connection lug passes through the cooperation crimping of screw and nut and extremely goes up at earthing for work. The beneficial effects are that: under the condition that does not influence three -phase short circuit grounding normal use, accessible quick change coupler realizes the high -speed joint to extension to suitable length, easy operation, low cost, the lower distribution lines of shaft tower is also all applicable.
Description
Technical field
This utility model relates to a kind of power system security Work tool field, can prolonged type three-phase shortcircuit earth lead particularly to one.
Background technology
Overhead distribution constructs, set up, speedily carry out rescue work during, installing three-phase shortcircuit earth lead is the residual charge in order to discharge in circuit, and prevents from sending a telegram here suddenly, is to ensure that an important content in safe technical measures.At present, 6kv, 10kv overhead distribution line line pole tower is mostly 10 meters, 12 meters, but at some scissors crossing, such as high-voltage electric power circuit, in railway, highway, provincial highway, urban street etc. at scissors crossing, and 15 meters, 18 meters of shaft towers get more and more.Original three-phase shortcircuit earth lead produces substantially according to less than 12 meters pole and tower design, construct at overhead distribution, set up, speedily carry out rescue work in such as this shaft tower time, original three-phase shortcircuit earth lead falls short of, operator may use and ground lead are wound around bracing wire or use other materials, such as steel strand wires, aluminum stranded conductor etc., the mode connecting temporary grounding pole carries out installing three-phase shortcircuit earth lead, is so absolutely unsafe.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that one can prolonged type three-phase shortcircuit earth lead.
Its technical scheme is: include insulating bar, three-phase type earth lead, copper Wiring nose, screw, nut, quick change male joint, quick change female joint, copper ground lead, temporary grounding pole, one end of three-phase type earth lead connects three insulating bars, the other end connects copper Wiring nose, one copper quick change male joint of crimping in parallel above copper Wiring nose, quick change male joint is by being connected copper ground lead with quick change female joint, the other end of copper ground lead connects copper Wiring nose, and copper Wiring nose is crimped on temporary grounding by the cooperation of screw and nut and extremely goes up.
Above-mentioned quick change male joint is provided with projection, and the inside of quick change female joint is provided with draw-in groove.
The beneficial effects of the utility model are: do not affecting in the case of three-phase shortcircuit earth lead normally uses, can realize quickly connecting by hydraulic quick coupler, and extend to appropriate length, simple to operate, with low cost, and the relatively low distribution line of shaft tower is the most applicable.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the structural representation of quick change male joint；
Accompanying drawing 3 is the structural representation of quick change female joint；
In upper figure: insulating bar 1, three-phase type earth lead 2, copper Wiring nose 3, screw 4, nut 5, quick change male joint 6, quick change female joint 7, copper ground lead 8, temporary grounding pole 9, projection 6.1, draw-in groove 7.1.
Detailed description of the invention
In conjunction with accompanying drawing 1-3, the utility model will be further described:
This utility model includes insulating bar 1, three-phase type earth lead 2, copper Wiring nose 3, screw 4, nut 5, quick change male joint 6, quick change female joint 7, copper ground lead 8, temporary grounding pole 9, one end of three-phase type earth lead 2 connects three insulating bars 1, the other end connects copper Wiring nose 3, one copper quick change male joint 6 of crimping in parallel above copper Wiring nose 3, quick change male joint 6 is by being connected copper ground lead 8 with quick change female joint 7, the other end of copper ground lead 8 connects copper Wiring nose 3, copper Wiring nose 3 is crimped on temporary grounding pole 9 by the cooperation of screw 4 and nut 5.
Wherein, quick change male joint 6 is provided with projection 6.1, and the inside of quick change female joint 7 is provided with draw-in groove 7.1.
Original 6kv, 10kv overhead distribution three-phase shortcircuit grounding wire mounting be located at 15 meters, 18 meters of shaft towers fall short of time, copper quick change male joint is crimped with parallel connection above the copper Wiring nose of junction, former three-phase shortcircuit earth lead temporary grounding pole, use and crimp copper quick change female joint with copper ground lead one end of former three-phase shortcircuit earth lead same model, other end crimping copper Wiring nose；When extending three-phase shortcircuit earth lead, being connected with the copper Wiring nose of prolongation temporary grounding pole, the copper quick change male joint that other end quick change female joint crimps with former three-phase shortcircuit earth lead is connected, and can complete.
This utility model is not affecting in the case of three-phase shortcircuit earth lead normally uses, and can realize quickly connecting by hydraulic quick coupler, and extend to appropriate length, simple to operate, with low cost, and the relatively low distribution line of shaft tower is the most applicable.
The above, be only preferred embodiment of the present utility model, and this utility model is all revised possibly also with the technical scheme of above-mentioned elaboration or is revised as the technical scheme of equivalent by any those of ordinary skill in the art.Therefore, any simple modification carried out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that this utility model is claimed.
