Background technique
The basic structure of compound disc insulator used at present is to continue to use the structure of traditional porcelain insulator gradually to send out
What exhibition was evolved, it is inevitable there are still one even if having invented the composite disc insulator of core glass later
The problem of, that is, it is lacked between insulator core and steel feet and chapeau de fer because the reasons such as contraction of binder generate small crackle
It falls into, needs composite silicone rubber tightly to be wrapped up, but be also inevitably present the problem of breakdown forms zero resistance insulator.Such as
The utility model patent number 2015202041044 of the applicant, title are as follows: " in a kind of insulator for being combined with chapeau de fer and steel feet
Core ", it is still then structure that split production is bonded together by binder from each other.There is also above-mentioned problems.Needle
To this problem, the present inventor has done to be studied in earnest, proposes goal of the invention of the invention.
Summary of the invention
Goal of the invention of the invention is put forward to overcome deficiency existing for above-mentioned insulator core.Provide one
The compound disc insulator of kind new construction.
The technical solution of the invention is as follows is achieved, the compound disc insulator of this kind of new construction, has chapeau de fer,
Steel feet, core and core lower part work department and silicon rubber umbrella skirt, it is characterised in that chapeau de fer (1), steel feet (3), composite core
The core work department (4) and silicon rubber umbrella skirt (5) of body (2) and its underpart are one-time formed composite core and silicon rubber
The compound disc insulator of the composite structure of full skirt.
The manufacturing method of the compound disc insulator of this kind of new construction, it is characterised in that:
One, chapeau de fer and steel feet are fixed in ready tooling, tooling include fixed chapeau de fer, steel feet fixation device and
The mold closing mechanism of composite core forming, chapeau de fer is vertically coaxial with steel feet, under the action of the piston thrust of injection cylinder, with
At a high speed, high pressure, by the indoor composite of storing through nozzle injection into the type chamber of mold, the composite in type chamber passes through
After pressure maintaining, cooling, solidifying and setting, mold is under the action of clamping, opening mold, and by liftout attachment stereotyped
Product is from mould ejection；
Two, the composite structure of the chapeau de fer obtained among the above, steel feet and composite core is put into the height with silicon rubber
In warm sulfurizing mould, process is high temperature vulcanized, keep the temperature, demoulding obtains a kind of compound disc insulator of new construction.
The beneficial improvement having the technical effect that through structure and manufacturing process of the invention, solve it is traditional it is compound absolutely
Edge production needs to be integrated chapeau de fer, steel feet and insulator core mucilage binding by cement glue, then enter pond or
It being conserved in other media, technique is cumbersome, and the low problem of yield rate, one-shot forming technique is simple, high yield rate, and it is light-weight, more preferably
Ground ensure that the safe operation of power grid.
It is light-weight by the way that core, material and the improvement for manufacturing pouring technology, composite material core intensity is high,
Electric property is superior, and with insulator integral one-step molding, avoid the waste product problem in insulator compound processing course, mention
High processing quality and quality, traditional porcelain core will not occur and occur the problem of zero, core glass is revealed, subtracting significantly
Maintenance workload is lacked, has been the renewal product of compound disc insulator more satisfactory at present.
