Abstract

The utility model discloses a kind of columnar insulator with liner, insulating cylinder (2) with two ends assembling gold utensil seat (1), insulating cylinder inside has skeleton (4), it is characterised in that have the liner of inner core (3) composition in the inside of insulating cylinder (2).Its advantage is that the liner of columnar insulator can effectively improve the internal intensity of insulator, it is to avoid the problems such as the deformation produced because diameter is excessive.And the reform and innovation of gold utensil so that the matching property of cartridge type insulator is improved, and effectively avoids the problems such as being failed because the gold utensil that barrel distortion etc. causes is insecure with insulator cooperation.Particularly, hollow liner can also pass through cable from the inside of insulator, improve the performance of insulator.

Description

A kind of columnar insulator with liner

Technical field

The utility model belongs to the insulator in power equipment, is specifically a kind of columnar insulator with liner.

Background technology

For now widely used columnar insulator, major diameter, generally according to design requirement, make hollow shape Cartridge type, the inwall of traditional cartridge type insulator skeleton is smooth, but there is internal creep age distance in actual use not Enough influence the normal problem for using.Simultaneously because the reason for cylindrical structure, when diameter is further increased, coordinating with insulator Gold utensil in its binding site, the barrel distortion for insulator easily occur is difficult to be fixed with gold utensil, gold utensil and cylinder are released etc. asks Topic, in order to solve these problems, designer of the present utility model has done and has studied in earnest, it is proposed that invention mesh of the present utility model 's.

The content of the invention

Goal of the invention of the present utility model puts forward to overcome above-mentioned not enough.One kind is provided to carry The columnar insulator of liner.

Technical solution of the present utility model is achieved in that the columnar insulator with liner, with two ends The insulating cylinder (2) of assembling gold utensil seat (1), insulating cylinder inside has skeleton (4), it is characterised in that have in the inside of insulating cylinder (2) There is the liner that inner core (3) is constituted.

Of the present utility model beneficial has the technical effect that：The liner of columnar insulator can effectively improve the inside of insulator Intensity, it is to avoid the problems such as the deformation produced because diameter is excessive.And the reform and innovation of gold utensil so that the conformability of cartridge type insulator Can be improved, effectively avoid and fail etc. and to ask because the gold utensil that barrel distortion etc. causes and insulator coordinate insecure Topic.Particularly, hollow liner can also pass through cable from the inside of insulator, improve the performance of insulator.

Brief description of the drawings

Fig. 1 is solid inner lining structure profile of the present utility model, and Fig. 2 is the A-A profiles of Fig. 1, and Fig. 3 is the B-B of Fig. 1 Profile；Fig. 4 is the simplified structural representation of the hollow liner of another embodiment of the present utility model.Serial number in accompanying drawing： 1st, gold utensil seat, 2, insulating cylinder, 3, inner core, 4, skeleton, 5, gold utensil two, 6, gold utensil three, 7, hollow bushing pipe.

Specific embodiment

The embodiment be given in below in conjunction with the accompanying drawings, to structure of the present utility model and using being described in detail.Reference Accompanying drawing, a kind of columnar insulator with liner, the insulating cylinder (2) with two ends assembling gold utensil seat (1), insulating cylinder inside tool There is skeleton (4), it is characterised in that there is the liner of inner core (3) composition in the inside of insulating cylinder (2).

Used as an alternative embodiment of the invention, its distinguishing characteristics is that the liner of described insulator is a hollow lining Pipe (7).

Referring to the drawings 1 and Fig. 3, in order to improve the structural strength of insulator, the structure to gold utensil is redesigned, described The gold utensil of insulator be the gold utensil two with the annular groove coordinated with the inside and outside wall of insulating cylinder (2).

Referring to the drawings 4, in order to improve the application performance of insulator, the gold utensil of described insulator be with hollow The gold utensil three with through hole that the insulating cylinder (2) of bushing pipe (7) coordinates.The gold utensil three can also use the structure type of gold utensil two, The simply through hole in center than gold utensil more than two.Planform as shown in the dotted line of Fig. 4 middle and lower parts.
