Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of overvoltage as shown in Figs. 1-3 to automatically adjust protective device, including conducting wire 1 and cross-arm 2,
Adjusting rod 4 is fixed on the mounting plate 3 of 2 side of the cross-arm, the adjusting rod 4 is sheathed on the set of 5 bottom of insulator body
The inside of cylinder 6, the top of 2 other side of the cross-arm are equipped with the protective device 8 to match with insulator body 5, the protection dress
It includes between wiring ball-type electrode 9, ground connection spheric electrode 10 and wiring ball-type electrode 9 and the parallel connection of ground connection spheric electrode 10 to set 8
Gap 11 forms, and the wiring ball-type electrode 9 is set on the upper fixed gold utensil 12 being fixedly installed on conducting wire 1, the spherical electricity of the ground connection
Pole 10 is fixed on lower fixed gold utensil 14, and is grounded spheric electrode 10 and is connected with current limiting element 15, the current limiting element 15
The adjusting sleeve 16 of bottom is sheathed on the outside of supporting rod 17, and the bottom of the supporting rod 17 is welded on sliding block 19, the cunning
Block 19 and the sliding slot 20 at 2 top of cross-arm are slidably connected.
Specifically, be spirally connected by the first fastening bolt 7 between the sleeve 6 and adjusting rod 4, first fastening bolt 7
There are three annular is spaced substantially equidistant and sets, and sleeve 6 is equipped with the screw hole to match with the first fastening bolt 7.
Specifically, conducting wire 1 is withstood on the top of the insulator body 5.
Specifically, the wiring ball-type electrode 9 is connected by fixing clamper 13 and conducting wire 1.
Specifically, being spirally connected by the second fastening bolt 18 between the adjusting sleeve 16 and supporting rod 17, described second is tight
There are three 18 annular of fixing bolt is spaced substantially equidistant and sets, and adjusts sleeve 16 and be equipped with the spiral shell to match with the second fastening bolt 18
Hole.
Specifically, the shape of the sliding block 19 is H-shaped, it is spirally connected by bolt between the sliding block 19 and sliding slot 20, it is described
The front and rear sides level of sliding slot 20 is densely covered with the screw hole that several threaded holes on sliding block 19 match.
The overvoltage automatically adjusts protective device, and wiring ball-type electrode 9 and ground connection spheric electrode 10 are parallel to insulator
5 both ends of ontology make the impulse sparkover voltage of parallel connection gaps 11 more slightly lower by discharge voltage when being struck by lightning than insulator, in this way, sending out
When raw lightning stroke circuit, 11 arc leading angle of parallel connection gaps guides to electric arc the position in gap, and such electric arc is just had no idea insulation of burning
Sub- ontology 5.And when thunder and lightning punctures, parallel connection gaps 11 puncture one kind that it belongs to pure air breakdown, can be by wind-force, electronic
The factor of power influences, and electric arc is attracted by arc leading angle, and is elongated, and is convenient for arc extinction in this way, reduces lightning stroke probability of sustained arc.Meanwhile
Since pure air gap is gone to dissociate by force, after tripping, gap insulation restores circuit at once, increases reclosing successful reclosing rate,
So the device can effective protection insulator body 5, extend its service life, moreover it is possible to improve circuit re-switching success rate.
