Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of lightning protection line pole type composite insulator of adjustable arcing distance, can according to the situation of the different thunderstorm season in locality, preset arcing distance in advance, avoid the starting rod fusing that causes apart from too small or arcing distance is excessive makes the problems such as the damage of paired transmission line, also improve the structure of penetrating cable clamp, by put or linear contact lay changes long wire clamp and contacts with the face between wire.Concrete technical scheme is as follows:
A kind of lightning protection line pole type composite insulator of adjustable arcing distance, comprise insulating shield and be arranged at the clamp gold utensil be made up of upper holder block and lower lock block in described insulating shield, described lower lock block side connects the connecting portion of starting rod, and described lower lock block connecting insulator, described insulator lower end arranges lower steel pin, and the lower end of described starting rod is near described lower steel pin, it is characterized in that: for being coupling between described starting rod and lower lock block, lower lock block side arranges hemispherical protrusions, the connecting portion of starting rod arranges the hemispherical concave depressions of corresponding formation, rotating shaft embeds in the axis hole of described recess both sides through described protuberance, the axle portion arranged outside stop nut on lower lock block top, described stop nut abuts with starting rod,
The end arranged outside screw thread of described starting rod, described in be threaded in interface swivel nut, hold-down nut to be arranged on described screw thread and with interface swivel nut close contact.
Described upper holder block and lower lock block all arrange clamp groove, and the two ends of described clamp groove arrange through hole, and bolt is through described through hole and nut and then upper holder block and lower lock block are fixed; Arrange puncture portion arranged in parallel in the clamp groove of described upper holder block, the length in the puncture portion of described upper holder block is different; Arrange puncture portion in the groove of described lower lock block, the length in the puncture portion of described lower lock block is not identical yet yet.
The utility model has the advantages that: due between starting rod and lower lock block for being coupling, therefore, the radial distance between adjustable starting rod and earth terminal contact; In addition, due to the thread fixing structure of connecting portion, the axial distance also between adjustable starting rod and earth terminal contact, therefore, can adapt to different arcing distance requirements; In addition, the length in the puncture portion of upper holder block is different, can ensure after puncturing electric wire insulation layer, part puncture portion and wire metal tilt along the surface of wire metal under the effect of bolt force, therefore, penetrating cable clamp contacts with wire metal forming section face, adds contact area, ensure that the reliability of electrical connection.
