Abstract
The invention discloses a dual-mode distance-adjusting lightning protection line column-type composite insulator which comprises an insulating shield and a wire-clamping armour clamp arranged in the insulating shield and formed by an upper pressing block and a lower pressing block. A side end of the lower pressing block is connected to a connecting portion of an arc-striking rod, and the lower pressing block is connected to an insulator. The lower end of the insulator is provided with a lower steel pin. The lower end of the arc-striking rod is close to the lower steel pin. The arc-striking rod is in coupling with the lower pressing block. A side end of the lower pressing block is provided with a semispherical convex portion. A connection portion of the arc-striking rod is provided with a correspondingly formed semispherical concave portion. A rotating shaft passes through the convex portion to be embedded in shaft holes in the two sides of the concave portion. A shaft portion outside of the upper portion of the lower pressing block is provided with a space-limiting nut which is abutted against the arc-striking rod. The dual-mode distance-adjusting lightning protection line column-type composite insulator of the invention has advantages that the axial and radial distances between the arc-striking rod and a grounding end contact can be adjusted, therefore, the insulator can be adapted to different discharge distance requirements; and in addition, a puncture clip and an electric wire metal form partial surface contact, thereby increasing a contact area and ensuring the reliability of electrical connection.

The content of the invention
To solve above-mentioned technical problem, it is an object of the invention to provide a kind of lightning protection line pole type composite insulator of adjustable arcing distance, can be according to the situation of local different thunderstorm season, arcing distance is preset in advance, avoid the starting rod caused apart from too small fusing or arcing distance it is excessive make paired transmission line damage the problems such as, the structure of penetrating cable clamp is also improved, long wire clamp is changed by point or linear contact lay and is contacted 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, including the clamp gold utensil that insulating shield and being arranged in the insulating shield is made up of upper holder block and lower lock block, the lower lock block side connects the connecting portion of starting rod, and the lower lock block connecting insulator, the insulator lower end arranges lower steel foot, and the lower end of the starting rod is near the lower steel foot, it is characterised in that：Connect for axle between the starting rod and lower lock block, lower lock block side arranges hemispherical protrusions, the connecting portion of starting rod arranges the hemispherical concave depressions being correspondingly formed, and rotating shaft is embedded in the axis hole of the recess both sides through the convex portion；Stop nut is set on the outside of the axle portion on lower lock block top, and the stop nut is abutted with starting rod；
It is threaded on the outside of the end of the starting rod, described to be threaded in interface swivel nut, fixing nut is arranged on the screw thread and is in close contact with interface swivel nut.
The lower steel foot includes a bar portion, and one end of the bar portion screws in earth terminal and fixed with nut.
The upper holder block and lower lock block are respectively provided with clamp groove, and the two ends of the clamp groove arrange through hole, and upper holder block and lower lock block with nut and then are fixed by bolt through the through hole；Puncture portion arranged in parallel is set in the clamp groove of the upper holder block, and the length in the puncture portion of the upper holder block is different；Puncture portion is also provided with the groove of the lower lock block, the length in the puncture portion of the lower lock block is also differed.
It is an advantage of the invention that：Due to connecing for axle between starting rod and lower lock block, therefore, can adjust the radial distance between starting rod and earth terminal contact；Further, since the thread fixing structure of connecting portion, also can adjust the axial distance between starting rod and earth terminal contact, therefore, it is suitable for different arcing distance requirements；In addition, the length in the puncture portion of upper holder block is different, can ensure after electric wire insulation layer is punctured, a part of puncture portion is inclined along the surface of wire metal in the presence of bolt power with wire metal, therefore, penetrating cable clamp is contacted with wire metal forming portion facet, increased contact area, it is ensured that the reliability of electrical connection.
