Abstract
The utility model discloses a large-current telescopic high-altitude cable connecting clamp. The large-current telescopic high-altitude cable connecting clamp comprises a large-current multi-functional clamp, and further comprises a telescopic insulating rod. The large-current multi-functional clamp and the telescopic insulating rod are movably connected in detachable mode. Below an installation position, when the large-current telescopic high-altitude cable connecting clamp stays vertical status, the telescopic insulating rod can be expanded or pushed back directly, the telescopic insulating rod can be fixed in screwed mode in any length, and the expansion operation site is right below a test site. Moreover, the diameter of the telescopic insulating rod becomes smaller gradually, the telescopic insulating rod is relatively light in weight, an operator can easily hold the telescopic insulating rod, and no safety risk of the large-current telescopic high-altitude cable connecting clamp falling to neighboring high-voltage energized equipment exists. The large-current telescopic high-altitude cable connecting clamp can be used to completely replace existing various types of plug-in type insulating rod high-altitude cable connecting clamps, and has the advantages of being multifunctional, convenient to manage, safe, reliable and the like.
Description
Technical field
The utility model relates to a kind of high-altitude wiring device, the telescopic high-altitude wiring pincers of particularly a kind of big electric current.
Background technology
The multi-functional high-altitude wiring pincers of using in the present domestic power system are high voltage electric equipment to be carried out carry out the special fixture of patch in the detecting electric equipment work such as contact resistance, loop resistance, the test of CT no-load voltage ratio, withstand voltage test.It has solved the power system high-potting working site outstanding problems such as wiring labour intensity is big, the high bob security risk of personnel height of climbing to a higher point.
Because the insulating bar majority of existing most of high-altitude wiring pincers is to adopt the form of pegging graft, the longest 8 meters to every about about 1 meter the common insulating bar of the more piece lengthening of pegging graft, to adapt to the test needs of 110kV and above eminence equipment.This insulating bar is very heavy after pegging graft; Personnel hold painstakingly; And when installing of high-altitude wiring pincers and dismounting, must under full length, carry out; Just in case operating personnel do not hold, very easily be poured onto adjacent high voltage alive equipment place, cause the electric network fault large-area power-cuts or cause operating personnel's electric arc burn.When improving testing crew operating efficiency, the high bob of elimination personnel risk, other risks that cause power grid accident, personnel's electric shock accidents have but been brought.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art, and provides a kind of and adapt to the field apparatus differing heights, can under plumbness, stretch, and is easy to use, can reduce the telescopic high-altitude wiring pincers of big electric current of electrician's labour intensity.
The telescopic high-altitude wiring pincers of a kind of big electric current; Comprise the multi-functional clamp of big electric current; Its structural feature is: the telescopic high-altitude wiring pincers of described big electric current also include telescopic insulating bar, removably connect for activity between big multi-functional clamp of electric current and the telescopic insulating bar.
Multi-functional clamp of big electric current and telescopic insulating bar are linked together; Just can it be holded up in use and stretch, the thorny place of holding of insulating bar after good turn 90 degrees the angle and just can hold up with long grafting again thereby changed after need it being pegged graft in advance in the prior art, causes very difficulty of operation; The shortcoming that working strength of workers is very big; And so long insulating bar runs into adjacent lead easily and causes accident when holding up, have simple to operate, the convenient advantage of using.
The multi-functional clamp of described big electric current removably connects with activity between the telescopic insulating bar or is connected for both adopt the mode of grafting.
The multi-functional clamp of described big electric current removably connects with activity between the telescopic insulating bar or is threaded for adopting, or adopts connector such as latch to connect.
Described telescopic insulating bar is a kind of structure of nut screw mandrel, and the two ends that are provided with the rod member of external screw thread or internal thread at two ends are bolted with respectively and are provided with internal thread or externally threaded sleeve pipe within it.
In use, have externally threaded rod member through adjusting and can realize length adjustment this insulating bar.
In sum, the utility model is compared the following advantage of prior art:
The telescopic high-altitude wiring pincers of the big electric current of the utility model can directly stretch, shrink and be rotated in random length fixing under maintenance plumbness below the installing place to insulating bar, flexible operation place is exactly under examination geodetic point.And telescopic insulating bar is reduced step by step, and weight is light relatively a lot, and easy operating personnel hold, and it is low that nothing is poured onto the security risk of closing on high voltage alive equipment.Can substitute at present existing all kinds of plug-in type insulation bar high-altitude wirings pincers fully, it is many with, convenient management, advantage such as safe and reliable to have pincers.

Fig. 1 is the structural representation of the telescopic high-altitude wiring pincers of the big electric current of the utility model.
The multi-functional clamp 2 telescopic insulating bars of label declaration 1 big electric current.
The specific embodiment
Below in conjunction with embodiment the utility model is described in more detail.
Embodiment 1
The telescopic high-altitude wiring pincers of a kind of big electric current comprise multi-functional clamp of big electric current and telescopic insulating bar, removably connect for activity between big multi-functional clamp of electric current and the telescopic insulating bar.The multi-functional clamp of described big electric current is detachably connected as both with activity between the telescopic insulating bar and adopts the mode of grafting to be connected.Described telescopic insulating bar is a kind of structure of nut screw mandrel, and the two ends that are provided with the rod member of external screw thread or internal thread at two ends are bolted with respectively and are provided with internal thread or externally threaded sleeve pipe within it.
It is identical with prior art that present embodiment is not stated part.
