Abstract
The utility model relates to a combined lighting arrester element, having a core and a high-voltage cable. The end portion of the core is provided with connection screw pores, an insulation sleeve is in socket connection with the core. The end portion of the high-voltage cable includes a screw connection portion. The screw connection portion of the high voltage cable passes through an insulation sleeve and is threaded in the connection screw pore of the core. The high voltage cable, the core and the insulation sleeve of the utility model are all manufactured independently, and then assembled together, the positioning is simple and convenient, parts can be independently replaced in order to reduce the maintenance cost. The high voltage cable and the core can connected through screw, the installation is firm and reliable, and the lighting arresting effect is great. An electric protection portion is provided on the upper portion of the insulation sleeve, which can protect the high voltage cable from break due to excessive bending, and has reasonable design.
Description
Technical field
The utility model relates to a kind of outdoor thunder resisting equipment, particularly a kind of combined arrester element.
Background technology
The combined arrester element is main, the most key part of combined arrester, every performance of lightning arrester and effect also all are embodied on the unit of an arrester, so whether the performance design of combined arrester element rationally is the key of weighing the combined arrester performance.
Traditional combined arrester element is an one, the core body of high-tension cable and the inside is once molding formed, this forming method can cause the location of core body in die cavity can only lean on the bolt of an end core body to locate, can make high-voltage cable extrusion flow movable property because of sizing material in forming process of core body give birth to skew, influence the performance of lightning arrester, make the percent defective of lightning arrester when moulding higher, increased the manufacturing cost of lightning arrester.
The utility model content
The purpose of this utility model is to provide a kind of location simple, the combined arrester element that core body and high-tension cable are all replaceable and lightning-arrest performance is good, percent defective is low.
The technical scheme that realizes the utility model purpose is: a kind of combined arrester element has core body and high-tension cable; Described core body end is provided with the connection screw, the outside socket insulating case of core body, and described high-tension cable end has threaded joints, and the threaded joints of high-tension cable passes insulating case and is rotated with in the connection screw of core body.
The core body upper/lower terminal of combinations thereof formula unit of an arrester is equipped with the connection screw, and all is arranged on the center, end.
The insulating case of combinations thereof formula unit of an arrester is that elastomeric material is made, and its top is provided with cable protection portion, is provided with the through hole that can allow high-tension cable pass in the cable protection portion.
The utlity model has following characteristics: (1) high-tension cable of the present utility model, core body and insulating case are the split manufacturing, fit together then, locate simple and conveniently, and replacement part separately reduces maintenance cost; (2) high-tension cable of the present utility model and core body be by being threaded, and be solid and reliable, lightning-arrest effective; (3) the utility model insulating case top is provided with cable protection portion, can protect high-tension cable can not fracture in the local excessive bending, and is reasonable in design.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, the utlity model has core body 1 and high-tension cable 3; Described core body 1 upper/lower terminal is equipped with and connects screw 11; and all be arranged on the center, end; core body 1 outside socket insulating case 2; insulating case 2 is made for elastomeric material; its top is provided with cable protection portion 21; be provided with the through hole that can allow high-tension cable 3 pass in the cable protection portion 21, high-tension cable 3 ends have threaded joints 31, and the threaded joints 31 of high-tension cable 3 passes insulating case 2 and is rotated with in the connection screw 11 of core body 1.
During production; earlier touch the core body 1 and the insulating case 2 of lightning arrester molded respectively; the cable protection portion 21 of then threaded joints of high-tension cable 3 ends being passed insulating case 2 is rotated with in the connection screw 11 of core body 1; again insulating case 2 is socketed on the core body 1; so not only solve unborn problem; the dielectric strength of combined arrester integral body is improved greatly, the lifting of also better more science the combination property of combined arrester.
