Abstract
The utility model provides a post insulator structure. The bending resistance of a common post insulator with a voltage above 220kV is over 40kN, and requirements on the bending resistance of the post insulator are increased along with the increase of voltage. The post insulator structure comprises an umbrella skirt, a mandrel and a plurality of steel cores, wherein the umbrella skirt is formed by vulcanizing a polymer polymerization material which uses silica gel as matrix at high temperature; the mandrel is formed by casting or mould pressing; the steel cores are arranged at the bottom of the mandrel; and the steel cores and the mandrel have concrete structures. The mechanical strength of the post insulator structure is greatly increased, and torsion resistance is also greatly increased.
Description
Technical field
The utility model relates to insulator and makes the field, relates in particular to a kind of post insulator structure.
Background technology
Post insulator is a kind of special insulation control, can play an important role in overhead transmission line.The general porcelain of traditional post insulator, made by silica gel 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 post insulator structure, 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 post insulator structure comprises full skirt, plug, steel core, wherein, full skirt for the macromolecule polymeric material take silica gel as parent through high temperature vulcanized forming; Plug is that casting or mold pressing form, and there are many steel cores the plug bottom; Steel core, plug consist of concrete structure.
A kind of post insulator structure that the utility model provides has many steel cores in the plug bottom, and steel core, plug consist of concrete structure, have greatly improved the mechanical strength of post insulator, have also greatly improved anti-twisting property simultaneously.
