Description

A kind of anti-thunder insulator for overhead transmission line
Technical field
The utility model relates to a kind of insulator, particularly relates to a kind of anti-thunder insulator for overhead transmission line.
Background technology
Insulator is a kind of special insulation control, can play an important role in overhead transmission line.It is the main body of transmission line insulator, and its effect is hung wire and makes wire keep insulating with shaft tower, the earth.The most complex structure of existing insulator, cost is higher.General setting umbrella rib structure on the insulator can not ensure the creepage distance of discharging gap well.And the electric discharge arc-striking structure on general insulator is mostly just disposable, and play lightning protection effect when there is thunderbolt, damage, useful life is very short simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art and provides a kind of anti-thunder insulator for overhead transmission line, can not only ensure the creepage distance of discharging gap well, have very long lightning protection useful life simultaneously.
The technical scheme realizing above-mentioned purpose is:
For an anti-thunder insulator for overhead transmission line, comprise insulator body, be fixed on the clamp gold utensil of described insulator body upper end and be fixed on the lower steel pin of described insulator body lower end, also comprise:
Be connected to described clamp gold utensil side and the starting rod of the described lower steel pin of bending sensing;
With the termination of described starting rod every Kongxiang to and be fixed on the hemisphere jut of described lower steel pin side; And
Cover fastens the insulating cover of described clamp gold utensil;
The outer wall of described insulator body is provided with three layers of umbrella rib, and these three layers of umbrella ribs diameter separately successively reduces from top to bottom.
Above-mentioned in the anti-thunder insulator of overhead transmission line, described clamp gold utensil comprises:
Be fixed on described insulator body upper end and have the gold utensil body of the first arc groove; And
To be fixed on above described gold utensil body and to have the wire pressing block of the second arc groove, the threading hole that described first arc groove and the synthesis of the second arc groove are passed for insulated conductor.
Above-mentioned in the anti-thunder insulator of overhead transmission line, the described insulated conductor part be in described threading hole is bare wire.
Above-mentioned in the anti-thunder insulator of overhead transmission line, in described second arc groove, be distributed with tooth bar.
The beneficial effects of the utility model are: the utility model, by diameter diminishing umbrella rib structure from top to bottom, ensure that the creepage distance of discharging gap, and the bounce-back increasing power frequency continued flow electric arc is interval, to reduce lightning stroke trip probability.Meanwhile, the structure of starting rod is utilized effectively to extend the lightning protection useful life of insulator.
Accompanying drawing explanation
Fig. 1 is the structural representation of the anti-thunder insulator for overhead transmission line of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1, the anti-thunder insulator for overhead transmission line of the present utility model, comprise insulator body 1, clamp gold utensil 2, lower steel pin 3, starting rod 4, hemisphere jut 5 and insulating cover 6, wherein,
Clamp gold utensil 2 is fixed on the upper end of insulator body 1, particularly, comprises gold utensil body 21 and wire pressing block 22.Gold utensil body 21 is fixed on the upper end of insulator body 1, and has the first arc groove.Wire pressing block 22 is fixed on the top of gold utensil body 21 by supporting screw rod, nut, and has the second arc groove.The threading hole that first arc groove and the synthesis of the second arc groove are passed for insulated conductor 7.Insulated conductor 7 part be in threading hole is bare wire, and insulating cover 6 cover fastens clamp gold utensil 2.In order to prevent insulated conductor 7 from sliding, in the second arc groove, be distributed with tooth bar 8.
Lower steel pin 3 is fixed on the lower end of insulator body 1.Starting rod 4 is connected to clamp gold utensil 2 side and lower steel pin 3 is pointed in bending, the termination of starting rod 4 be fixed on the hemisphere jut 5 of lower steel pin 3 side every Kongxiang pair.Thus the electric arc guided through starting rod 4 burns between starting rod 4 and hemisphere jut 5, thus avoids starting rod 4 and lower steel pin 3 directly to damage because of thunderbolt.
The outer wall of insulator body 1 is provided with three layers of umbrella rib 11, and these three layers of umbrella ribs diameter separately successively reduces from top to bottom, thus ensures the creepage distance of discharging gap, and the bounce-back increasing power frequency continued flow electric arc is interval, to reduce lightning stroke trip probability.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, when not departing from spirit of the present utility model, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present utility model, should be limited by each claim.
