Abstract
The utility model discloses a compound suspension insulator equipped with a sealing ring. The compound suspension insulator comprises an iron hat (1), an iron cap binder (2), an inner core (3), a steel pin binder (4) and a steel pin. The iron hat is solidified with the inner core through the iron hat binder. The steel pin is solidified with the inner core through the steel pin binder. One to three silicone rubber umbrella skirt sleeve(s) (7) are arranged on a disc surface of the inner core. A sealing ring (6) is arranged at the connecting part of the iron cap and the silicone rubber umbrella skirt sleeve(s) (7). The compound suspension insulator is characterized in that, a sealant layer (8) is arranged at a junction of the inner iron hat and the iron hat binder with the inner core. The compound suspension insulator has the advantages that, a structure of a die and positioning basis are simplified, sealing performance between a silicone rubber surface and the iron hat binder is improved, icing of ponding caused by a gap between the silicone rubber umbrella skirt sleeve and the iron hat binder is prevented, and service life and performance of the compound suspension insulator are improved.
Description
Technical field
The utility model belongs to the insulator using in electric power power transformating and supplying facility, and definite saying is a kind of composite suspension type insulators with seal ring structure.
Background technology
Composite suspension type insulators is widely used at present, and the composite suspension type insulators of multi-parachute skirt has also obtained application the most widely.In Design and manufacture technique due to composite suspension type insulators, need to make inner core through pottery or glass technology; Chapeau de fer, steel pin need to be cured as one by binding agent and inner core; The dish-type surface of inner core needs the multiple working procedures such as composite silicone rubber just can become composite suspension type insulators finished product.All the time, in composite silicone rubber full skirt technique, cannot solve the clearance issues existing between silastic surface and chapeau de fer binding agent, this structural defect, often cause in use, particularly northern China use in winter, produces the icing problem of ponding because the pass of sleet ties up in this gap, and has influence on the use of insulator.Once proposed solution, applied for utility model patent, the patent No. 201020566610.5, title: a kind of composite insulator of fitting tight ring.But due to reasons such as mismachining tolerances, the sealing of sealing ring is sometimes because error etc. are former thereby inefficacy.In order to address this problem, designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model puts forward for the defect that overcomes above-mentioned composite suspension type insulators and exist.A kind of composite suspension type insulators with seal ring structure is provided.
Technical solution of the present utility model is to realize like this, should be with the composite suspension type insulators of seal ring structure, there is chapeau de fer (1), chapeau de fer binding agent (2), inner core (3), steel pin binding agent (4) and steel pin (5), chapeau de fer is cured as one by chapeau de fer binding agent and inner core, steel pin is cured as one by steel pin binding agent and inner core, on the dish-type surface of inner core, there is 1-3 silicon rubber full skirt cover (7), connecting portion at chapeau de fer and silicon rubber full skirt cover has a sealing ring (6), it is characterized in that thering is sealant layer (8) at the intersection of the inside of sealing ring chapeau de fer and chapeau de fer binding agent and inner core.
Useful technique effect of the present utility model is: structure and the positioning datum of having simplified mould, improve the sealing property between silastic surface and chapeau de fer binding agent, avoid silicon rubber full skirt to overlap the ponding ice formation issues that has gap and cause between chapeau de fer binding agent, improved useful life and the performance of composite suspension type insulators.
Brief description of the drawings
Accompanying drawing 1 be 2 full skirts of the present utility model composite suspension type insulators partly cut open schematic diagram, accompanying drawing 2 be 3 full skirts of the present utility model composite suspension type insulators partly cut open schematic diagram.The composite suspension type insulators of single full skirt has just no longer drawn schematic diagram, and its structure is identical with the structure of 2,3 full skirts.Sequence number is in the accompanying drawings: 1, chapeau de fer, 2, chapeau de fer binding agent, 3, inner core, 4, steel pin binding agent, 5, steel pin, 6, sealing ring, 7, silicon rubber full skirt cover, 8, sealant layer.
Embodiment
Below in conjunction with the embodiment providing in accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this kind is with the composite suspension type insulators of seal ring structure, there is chapeau de fer (1), chapeau de fer binding agent (2), inner core (3), steel pin binding agent (4) and steel pin (5), chapeau de fer is cured as one by chapeau de fer binding agent and inner core, steel pin is cured as one by steel pin binding agent and inner core, on the dish-type surface of inner core, there is 1-3 silicon rubber full skirt cover (7), connecting portion at chapeau de fer and silicon rubber full skirt cover has a sealing ring (6), it is characterized in that thering is sealant layer (8) at the intersection of the inside of sealing ring chapeau de fer and chapeau de fer binding agent and inner core.The quantity of silicon rubber full skirt cover can arrange as required, is normal more than 3.
From application and manufacture angle, seal ring structure of the present utility model can adapt to the binding site of all composite suspension type insulators silicon rubber full skirts covers and chapeau de fer.Analog structure under this design, within also should belonging to technology category of the present utility model.
