Abstract
Generally, the bending resistance capability of a post insulator of more than 220kV is required to be more than 40kV, and the higher voltage is, the higher the requirement for the bending resistance capability of the post insulator is. The utility model provides a cone-shaped multilayer post insulator which comprises umbrella skirts, central core rods, peripheral core rods, wherein the umbrella skirts are formed by vulcanizing a high-molecular polymerization material with silica gel as a maternal body at high temperatures; the central core rods are conical; the peripheral core rods are adhered to the external surfaces of the central core rods in a binding or die pressing manner, and the central core rods and the peripheral core rods are combined to form a new shape of cone; and the umbrella skirts are adhered to the external surfaces of the peripheral core rods with a binder. The cone-shaped multilayer post insulator can bind a plurality of the central core rods and the peripheral core rods together in dependence on actual requirements and is good in insulating properties and high in mechanical strength, and the anti-torsion capability can be greatly improved by layers of a cone-shaped structure.
Description
Technical field
The utility model relates to insulator and makes the field, relates in particular to a kind of taper multilayer 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.Existing post insulator center is generally an insulating rod, and bending resistance is less.The bending resistance of the post insulator that general 220kV is above will reach more than the 40kN, and voltage is higher, and is also higher to the requirement of the anti-bending strength of post insulator.
The utility model content
For existing technical problem, the utility model provides a kind of taper multilayer post insulator, and mechanical strength is high, anti-twisting property is strong, is applicable to the application of 220kV and above contour voltage domain.To achieve these goals, technical solution adopted in the utility model is, a kind of taper multilayer post insulator comprises full skirt, center plug, peripheral plug, wherein, full skirt for the macromolecule polymeric material take silica gel as parent through high temperature vulcanized forming; The center plug is conical; In the outer surface of center plug, and center plug, peripheral plug are combined into a new taper shape to peripheral plug by the sticking note of the mode of bonding or mold pressing; Full skirt is by the sticking outer surface that is posted on peripheral plug of binding agent; The utility model can design many group switching centres plug, peripheral plug bonds mutually according to actual needs.
A kind of multilayer bending resistance post insulator that the utility model provides, good insulating, mechanical strength be high, the pyramidal structure by layer by layer, greatly improved anti-twisting property.
