Abstract

The utility model discloses a 35kV fuse connector comprising a pair of a nut with an inner thread and a screwed pipe with an outer thread, wherein the inner thread of the nut is matched with the outer thread of the screwed pipe; the screwed pipe consists of a first half screwed pipe and a second half screwed pipe, and the first half screwed pipe and the second half screwed pipe are provided with mutually matched concave body and convex body; and the inner cavity of the screwed pipe is matched with the neck of a safety porcelain bushing, and the nut and the screw pipes are made of aluminum or copper. The 35kV fuse connector disclosed by the utility model has the characteristics of simple structure, convenience to use, long service life and the like.

Description

A kind of 35kV fuse jockey

Technical field

The utility model relates to a kind of high voltage electric power equip ment, especially a kind of device that is connected with fuse.

Background technology

Carrying out during the 35kV of transformer station fuse insurance more changes jobs; Chang Yin is exposed to outdoor protecting cap fastening bolt corrosion seriously can't take off bolt replacing insurance; The insurance jockey of scrapping because of bolt corrosion is a lot, can only the integral replacing safeties, thereby cause significant wastage.

The utility model content

The technical problem that the utility model will solve provides a kind of 35kV fuse jockey, and it has characteristics such as simple in structure, easy to use, long service life.

For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: it comprises the insurance insulator, and it also comprises a pair of tapped nut and is with externally threaded screwed pipe in addition, and the internal thread of nut and the external screw thread of screwed pipe are suitable; Screwed pipe is made up of the first half-thread pipe and the second half-thread pipe; The inner chamber of screwed pipe is suitable with the neck of insurance insulator, and the material of nut is aluminium or copper.

The utility model further improves and is: the first half-thread pipe and the second half-thread pipe have adaptive concavo-convex body mutually; It also comprises the suitable O type rubber ring in edge with the insurance insulator.

Adopt the beneficial effect that technique scheme produced to be: the nut through adopting antirust conductor material (like copper or aluminium) to make is connected with the insurance insulator with screwed pipe; Substituted the former method that connects with the protecting cap fastening bolt; Prolonged the useful life of safeties; Avoided can't dismantling because of the corrosion of protecting cap fastening bolt and had to change the waste that whole safeties cause, this utility model also has characteristics such as simple in structure, easy to use.

In the accompanying drawings: 1, nut; 2, screwed pipe; 3, the first half-thread pipe; 4, the second half-thread pipe; 5, the neck of insurance insulator; 6, O type rubber ring; 7, the edge of insurance insulator; 8, insurance insulator.

Embodiment

Embodiment by shown in Fig. 1-4 can know that it comprises insurance insulator 8, and it also comprises a pair of tapped nut 1 and is with externally threaded screwed pipe 2 in addition, and the external screw thread of the internal thread of nut 1 and screwed pipe 2 is suitable; Screwed pipe 2 is made up of the first half-thread pipe 3 and the second half-thread pipe 4; The inner chamber of screwed pipe 2 is suitable with the neck 5 of insurance insulator 8, and the material of nut 1 is aluminium or copper; The first half-thread pipe 3 and the second half-thread pipe 4 have adaptive concavo-convex body mutually; It also comprises the suitable O type rubber ring 6 in edge 7 with insurance insulator 8.

Method for using:

Earlier the first half-thread pipe and the second half-thread pipe are fixed to the neck place of insuring insulator through concavo-convex body combination; Again O type rubber blanket is placed on the edge (prevent to squeeze and hinder the porcelain part) of insurance insulator; And then nut screwed in screwed pipe, and connecting lead at last again, can fulfil assignment.
