Abstract
The utility model relates to an over-current clamping device comprising a clamping device heavy end and a clamping device light end. The clamping device heavy end and the clamping device light end are connected by a copper wire and are formed by hook bodies, metal bases, and leading screws. Holes are arranged at the bottoms of the hook bodies and screw threads are arranged inside the holes. The top ends of the leading screws pass through the holes and then are fixedly connected with the metal bases; and the metal bases are driven by the leading screws to make up-and-down movements along the inner walls of the hook bodies. Besides, iron hoops are installed at the top ends of the hook bodies. According to the utility model, an insulation operating rod can be used to carry out ground potential installation and disassembling and thus it can be avoided that equipotential working personnel enter a high field to carry out installation, so that the working security is high and the operation is simple and convenient.
Description
Technical field
The utility model relates to the overcurrent jig that the charged disconnecting drainage method of a kind of suitable 66KV earth potential aluminium hydraulic pressed connecting pipe connecting plate uses.
Background technology
Traditional charged disconnecting of 66kV aluminium hydraulic pressed connecting pipe connecting plate is drawn work and is all adopted hard ladder to hang on the live wire; Equipotential personnel carry instruments such as overcurrent coaster and extinguishing arc rope and get into highfield; The overcurrent coaster that has the extinguishing arc rope at first is installed on aluminium hydraulic pressed connecting pipe; Remove the connecting plate screw then, then withdraw from highfield wait for broken off fully by disconnected drainage after.Because of extinguishing arc rope with by disconnected drainage still in connection status, so the equipotential operating personnel must advance people's highfield once more, take off overcurrent coaster and extinguishing arc rope, withdraw from highfield once more behind dismounting overcurrent coaster and the extinguishing arc rope, that accomplishes a phase wherein disconnectedly draws work.Conventional method needs continuously into and out of what twice highfield just can be accomplished a phase disconnectedly to draw work because of the equipotential operating personnel; For requiring the high live line working field of operational security; Therefore there are many potential safety hazards in the method, is badly in need of a kind of instrument of the extinguishing arc rope that can replace insulating.
The utility model content
The technical problem that the utility model will solve provides a kind of overcurrent jig, and this overcurrent jig has operational security height, characteristics simple to operation.
In order to solve the problem that prior art exists, the technical scheme that the utility model adopts is:
The overcurrent jig includes heavy end of jig and the light-duty end of jig, jig is heavy hold with the light-duty end of jig between be connected through copper cash; The heavy end of described jig all is made up of coupler body, metal holder and leading screw with the light-duty end of jig; The bottom of coupler body has the hole, is provided with screw thread in the hole, and the top of leading screw is passed the holder of Kong Houyu metal and is fixed together; Metal holder inwall along coupler body under the drive of leading screw moves up and down, and the top of coupler body is equipped with iron hoop.
Advantage and effect that the utility model had are:
The utility model is owing to include heavy end of jig and the light-duty end of jig, and the operating personnel may stand on the disconnected iron tower that draws beyond the safe distance of position, chooses shank with insulation and hangs over the heavy end of jig on the aluminium hydraulic pressed connecting pipe; Choosing shank with insulation again tightens the bottom leading screw; Be tightened in the light-duty end of jig the connecting plate root of drainage thread then equally, wait for disconnected draw end after, again with insulation choose shank jig heavy hold be pulled to iron tower ground connection together with drainage thread after colligation firm; Taking off the overcurrent jig at last finishes; The utility model can use the insulating bar earth potential to install and dismounting, removes the equipotential personnel from and gets into the highfield installation, and operational security is high, simple to operation.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Among the figure: the light-duty end of the heavy end of jig 1, jig 2, copper cash 3, coupler body 11, metal holder 12, leading screw 13, hole 14, iron hoop 15, coupler body 21, metal holder 22, leading screw 23, hole 24, iron hoop 25.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail:
As shown in Figure 1; The utility model overcurrent jig includes heavy end 1 of jig and the light-duty end 2 of jig; Reliably be connected through the long 400mm copper cash 3 of 16mm2 between the heavy end 1 of jig and the light-duty end 2 of jig, it is 1 identical with the structure of the light-duty end 2 of jig that the jig heavy type is held, and just varies in size.The heavy end of jig 1 is made up of coupler body 11, metal holder 12 and leading screw 13; The bottom of coupler body 11 has hole 14; Be provided with screw thread in the hole 14, the top of leading screw 13 is passed 14 backs, hole and is fixed together with metal holder 12, and leading screw 13 can move up and down by 14 interior screw threads along the hole; Metal holder 12 moves up and down along the inwall of coupler body 11 under the drive of leading screw 13, and the top of coupler body 11 is equipped with iron hoop 15.The light-duty end 2 of jig is made up of coupler body 21, metal holder 22 and leading screw 23; The bottom of coupler body 21 has hole 24; Be provided with screw thread in the hole 24, the top of leading screw 23 is passed 24 backs, hole and is fixed together with metal holder 22, and leading screw 23 can move up and down by 24 interior screw threads along the hole; Metal holder 22 moves up and down along the inwall of coupler body 21 under the drive of leading screw 23, and the top of coupler body 21 is equipped with iron hoop 25.The heavy end 1 of jig can be tightened on the aluminium hydraulic pressed connecting pipe with insulating bar, and the light-duty end 2 of jig can be tightened on the drainage thread with insulating bar, plays the effect of dredging electric current.
The method for using of the utility model is following:
The operating personnel stands on the disconnected iron tower that draws beyond the safe distance of position; At first choosing shank with insulation hangs over the heavy end 1 of jig on the aluminium hydraulic pressed connecting pipe; Choose shank and tighten bottom leading screw 13 with insulation again, be tightened in the light-duty end 2 of jig the connecting plate root of drainage thread then equally, wait for disconnected draw end after; Colligation is firm after choosing shank and be pulled to iron tower ground connection to the heavy end of jig 1 together with drainage thread with insulation again, directly takes off the overcurrent jig with hand at last and finishes.
