Abstract
The utility model discloses a post insulator and a current transformer using the same. The post insulator includes a tapered body which has a small top and a big bottom. The inside of the tapered body is provided with a tapered inner cavity which has a small top and a big bottom. The tapered inner cavity and the tapered body are coaxial. The peripheral face of the tapered body is evenly provided with multiple coaxial circular umbrella skirts along the axial direction of the tapered body. The circular umbrella skirts and the tapered body are formed into one body via integral pouring. The post insulator is an integral structure which is shaped by integrally pouring the tapered body and the multiple circular umbrella skirts, and the integral structure saves the splicing step in the prior art (in the splicing step, multiple single umbrella skirts which are different in specification are spliced), so the production assembly efficiency is improved, and the appearance of the seamless post insulator is beautiful, and the integral structure is high in strength.
Description
Technical field
The utility model belongs to the converting equipment technical field, is specifically related to a kind of post insulator and uses the current transformer of this post insulator.
Background technology
As shown in Figure 1, the post insulator 10 on existing 110KV dry-type current transformer top by according to a definite sequence from top to bottom successively the single full skirt 11 of bonding a plurality of different sizes consist of, this single full skirt 11 successively bonding structure is not only lost time when the bonding assembling, simultaneously because between adjacent full skirt, exist seam 12 to affect the profile of post insulator, and the single full skirt of different size all needs the mould of single poured with epoxy resin, so just wasted a large amount of manpowers and raw material, be unfavorable for reducing and make and assembly cost.
The utility model content
The purpose of this utility model is to provide a kind of post insulator, the technical problem that causes the assembling not attractive in appearance, bonding of post insulator profile to be lost time by bonding formation of a plurality of full skirts to solve prior art B-C post insulator; Simultaneously, the utility model also provides a kind of current transformer that uses above-mentioned post insulator.
For achieving the above object, post insulator provided by the utility model adopts following technical scheme: a kind of post insulator, comprise up-small and down-big cone body, has up-small and down-big conical internal cavity in this cone body, this conical internal cavity and cone body coaxial arrangement, be evenly equipped with a plurality of annular full skirts along cone body axial coaxial on the outer peripheral face of described cone body, described annular full skirt and cone body are the integrative-structure of integrated poured moulding.
The outside dimension of described annular full skirt equates.
Current transformer provided by the utility model adopts following technical scheme: a kind of current transformer, comprise post insulator, described post insulator comprises up-small and down-big cone body, has up-small and down-big conical internal cavity in this cone body, this conical internal cavity and cone body coaxial arrangement, be evenly equipped with a plurality of annular full skirts along cone body axial coaxial on the outer peripheral face of described cone body, described annular full skirt and cone body are the integrative-structure of integrated poured moulding.
The outside dimension of described annular full skirt equates.
The beneficial effects of the utility model are: post insulator provided by the utility model is the integrative-structure by cone body and the integrated poured moulding of a plurality of annular full skirt, this monolithic construction has been save in the prior art step by the single full skirt bonding assembly unit of a plurality of different sizes, improve and produce efficiency of assembling, so and because there is not the whole post insulator good looking appearance of seam, overall construction intensity is high.
Current transformer provided by the utility model comprises post insulator, this post insulator is the integrative-structure by cone body and the integrated poured moulding of a plurality of annular full skirt, the good looking appearance of whole post insulator, bulk strength is high, and when mounted, can be with the post insulator integral installation on current transformer, Effective Raise the efficiency of assembling of current transformer.
