Abstract
The utility model discloses a kind of pillar insulator.This pillar insulator comprises: insulator porcelain piece and metab; Wherein, afterbody and the metab of insulator porcelain piece are spirally connected, and are perfused with cement between the afterbody of insulator porcelain piece and metab.The technical problem that the insulator that the utility model solves existing porcelain iron clad structure easily ftractures when temperature changes.
Description
Technical field
The utility model relates to power domain, in particular to a kind of pillar insulator.
Background technology
In the construction of 10kV overhead distribution, straight line pole generally adopts pin insulator (P15 type or P10 type), and the structure of above-mentioned pin insulator is " disk pack iron ", and namely its structure is followed successively by porcelain, cement and metal stitch from outside from inside.
It should be noted that, the stitch higher due to thermal coefficient of expansion and cement are included in the lower porcelain piece face of thermal coefficient of expansion, and when ambient temperature changes or the cement glue moisture absorption, porcelain piece inside can produce the tensile stress of repetition, and the anti-tensile resistance of porcelain is weak, easy generation cracking cracks, and in the process of porcelain piece making, if it is improper to fill a prescription, the mixing of technological process Raw is uneven, roasting is half-cooked, then easily form pore and absorb extraneous moisture, cause and puncture.
For insulator easy problem of Cracking when temperature changes of above-mentioned existing porcelain iron clad structure, at present effective solution is not yet proposed.
Utility model content
The utility model embodiment provides a kind of pillar insulator, the technical problem easily ftractureed when temperature changes with the insulator at least solving existing porcelain iron clad structure.
According to an aspect of the utility model embodiment, provide a kind of pillar insulator, comprising: insulator porcelain piece metab; Wherein, afterbody and the metab of insulator porcelain piece are spirally connected, and are perfused with cement between the afterbody of insulator porcelain piece and metab.
Further, the head of insulator porcelain piece has groove.
Further, insulator porcelain piece is with full skirt.
Further, the afterbody of insulator porcelain piece is connected by steel foot bolt with metab.
Further, steel foot bolt is configured with successively: plain cushion, spring pad, hexagonal standard nut and hexagonal lock narrow nut.
Further, steel foot bolt surface is coated with hot galvanized layer.
Further, insulator porcelain piece is solid.
Further, the radius of groove is 25mm.
In the utility model embodiment, pillar insulator comprises: insulator porcelain piece and metab; Wherein, afterbody and the metab of insulator porcelain piece are spirally connected, and are perfused with cement between the afterbody of insulator porcelain piece and metab, the technical problem that easily ftractures when temperature changes of the insulator solving existing porcelain iron clad structure.
Accompanying drawing explanation
