Background technology
A kind of current lightning protection strut composite insulator, support insulator and arc-preventing metal utensil are united two into one, such as China Patent Publication No. CN101325104B, its structure includes insulating shield and arranges the clamp gold utensil being made up of upper holder block and lower lock block in insulating shield, the clamp gold utensil side connection starting rod, and the clamp gold utensil lower end connecting insulator, antifouling cluster parachute is arranged with outside insulator.Insulator lower end arranges lower steel foot, and the lower end of starting rod is arranged near lower steel foot.But there is following defect in the lightning protection pillar insulator of this structure：1. the upper holder block and lower lock block of clamp gold utensil just clamps and punctures wire always with clamp nut and standby tight nut, during wire being punctured for the clamping for preventing upper holder block and lower lock block, damage wires, need the torque of wrenches that a scope is set according to factors such as the section of wire and day temperature temperature, and in actual mechanical process, Jing is often because the operating error of workman, torque of wrenches is excessive or too small, and cause wire impaired or wire in clamping process to be not reaching to optimal contact effect, have a strong impact on the performance of lightning protection pillar insulator；2. antifouling umbrella group structure arranges unreasonable, its back side is level design, in use, often pile up the dirts such as dust in the back side of antifouling cluster parachute, but when rainwater weather, rainwater cannot be drained into the antifouling cluster parachute backside structure of the level design back side of antifouling cluster parachute, and dirt is washed away, and antifouling capacity is poor.3. under the conditions of creep distance is met, umbrella footpath is excessive to easily cause full skirt and the wet sudden strain of a muscle level deficiency of the resistance to power frequency of starting rod.In order to solve above-mentioned technical problem, Chinese Patent Application No. 201220202149.4 discloses a kind of another lightning protection line pole type composite insulator, " 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 clamp gold utensil side connects starting rod; and the clamp gold utensil lower end connecting insulator; the insulator lower end arranges lower steel foot, and the lower end of the starting rod is arranged near the lower steel foot, it is characterised in that：The upper holder block and the lower lock block are connected by bolt and effective torque nut, constitute relative clamping or release that the effective torque nut rotation drives the upper holder block and the lower lock block." although the patent solves part the above, but do not solve following point：Because the distance of starting rod and earth terminal is fixed, such structure causes circuit power-off or damage the electric current that radar occurs is larger and during the longer persistent period, the end of starting rod can be punctured or be damaged；Additionally, it is point or linear contact lay either to puncture between shaped cable clamp and wire, loose contact is easily caused.
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；The axle portion outside on lower lock block top arranges stop nut, and the stop nut is abutted with starting rod；
The end outside of the starting rod is threaded, described to be threaded in interface swivel nut, and fixing nut is arranged on the screw thread and is in close contact with interface swivel 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 bolt with nut and then is fixed upper holder block and lower lock block 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 inclines in the presence of bolt power with wire metal along the surface of 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.
