Abstract

A traditional post insulator is generally made of glass or porcelain, and therefore pollution flashover of a surface and an accident occur easily under overcast, raining and foggy conditions. On the other hand, according to an exiting post insulator, a core column end of a support column is in a bonding connection with a metal accessory, and when torque of the support column is needed to be large, the structure usually can not reach the standard. The utility model provides a composite post insulator. The composite post insulator comprises an umbrella skirt, a core rod, a metal accessory and screw holes, wherein the umbrella skirt is formed by high temperature vulcanization of a macromolecule polymeric material using a silica gel as a parent body, the umbrella skirt is adhered to the outside surface of the core rod through binders, the screw holes are symmetrically disposed in the two sides of the metal accessory, and the metal accessory is fixed with the core rod through the screw holes. The composite post insulator has the advantages of being simple in preparation technology, good in insulativity, and high in mechanical strength, and having an excellent antifouling performance, and furthermore, pollution flashover voltage of the composite post insulator is 2-3 times higher than the pollution flashover voltage of a general porcelain post insulator, and torsion resistance is greatly enhanced by fixing of the screw holes.

Description

A kind of composite post insulator

Technical field

The utility model relates to insulator and makes the field, relates in particular to a kind of composite post insulator.

Background technology

Post insulator is a kind of special insulation control, can play an important role in overhead transmission line.Traditional post insulator is generally made by glass or pottery.Because its antifouling ability is relatively poor, behind the surface deposition dirt, insulation level can descend, and particularly descends in the moon, rain, mist condition, and pollution flashover occurs easily on the surface, causes the accident.On the other hand, existing post insulator passes through bonding connection between the stem stem end of its pillar and the metal-ware usually, although have simple in structure, easily manufactured having a few, but its anti-twisting property is poor, and when requiring the pillar moment of torsion larger, this structure is often not up to standard.

The utility model content

For existing technical problem, the utility model provides a kind of composite post insulator, and it can prevent pollution flashover accident effectively, mechanical strength is high, anti-twisting property is strong.To achieve these goals, technical solution adopted in the utility model is, a kind of composite post insulator comprises full skirt, plug, metal-ware, screw hole, wherein, full skirt for the macromolecule polymeric material take silica gel as parent through high temperature vulcanized forming; Full skirt is by the sticking outer surface that is posted on plug of binding agent; The monosymmetric screw hole that has on the metal-ware, metal-ware is fixed by screw hole and plug.

A kind of composite post insulator that the utility model provides, preparation technology is simple, good insulating, mechanical strength are high, have excellent antifouling performance, pollution flashover voltage than the general large 2-3 of porcelain pillar insulator doubly by fixing of screw hole, has strengthened antitorque ability greatly.
