Description
Technical field
The present invention relates to composite insulator technical fields, and in particular to a kind of Novel combined insulator further relates to a kind of multiple
Close the production technology of insulator.
Background technique
Organic composite insulator is as one of operation of power networks essential electrical component, in power Transmission and electrified iron
It plays an important role in the construction of road.And existing organic combined insulated production, there are two types of techniques altogether.One is general injections
Moulding process, another kind are to go here and there umbrella technique after extrude sheath, this 2 kinds of techniques respectively have in organic composite insulator production it is respective from
The shortcomings that body can not overcome
Integral injection molding technique is first to smear in organic composite insulator framework material plug and connection gold utensil surface
One layer of primer (silicon rubber coupling agent) then carries out the injection moulding of insulator umbrella sheath in rubber injection machine.This technique is deposited
The shortcomings that be: when integral injection molding, injector needs very big injection pressure silicon rubber could be full of die cavity, silicon rubber
In die cavity when high-pressure flow, plug fitting surface primer is washed away, interface bonding is caused loosely, easily forms product interior insulation not
It is good.When silicon rubber is injected, plug is positioned in mold by being located at the positioning pin of injection material mouth opposite metal manufacture, easy in this way
It causes positioning pin top to hurt plug, is broken product at runtime and goes offline.It is through excessive for the product of some high pressures, extra-high voltage
The production of whole branch insulator product umbrella sheath is realized in section injection, and due to taking stage injection technique, a long products just have
Many places are bonded interface, these interfaces are general injection handicraft product herein through detection and product in the operation of power grid high field intensity
Easy breakdown point.
String umbrella technique is extruded, is to extrude out one layer of silicone rubber jacket first on epoxy resin fiber stick surface on extruding machine,
Then blocks of full skirt set is through on silicone rubber jacket, is connected by room temperature vulcanized silicone rubber.Existing for the handicraft product
Distinct disadvantage is: the first, the material of bonding full skirt and silicone rubber jacket is room temperature vulcanized silicone rubber, and room temperature vulcanized silicone rubber exists
On mechanical performance, electric property and ageing properties, there are huge gaps with heat vulcanized silicone rubber；The second, between full skirt and sheath
It is bonded by room temperature vulcanized silicone rubber, two layers of connecting interface is increased on product；Third, full skirt itself sheath of set string are thin,
In operation, it easily falls after aging, is easily broken by big wind in wind area；4th, due to full skirt be penetrated in sheath one by one, therefore
Connection between each full skirt just leaves interface one by one in insulating surface, one by one interface, is exactly to bury one in insulator
Each and every one hidden danger.
Summary of the invention
It is an object of the invention to aiming at the shortcomings in the prior art, and provide a kind of good mechanical property, good electric property
The good Novel combined insulator with ageing properties, also provides the production technology of the composite insulator.
The purpose of the present invention is achieved through the following technical solutions: providing a kind of Novel combined insulator, including plug, silicon rubber

Acid anhydride: 6.7-9.2%, trimellitic anhydride: 3.3-5.8%, the sum of weight percentages of components are 100%；Step b, using sander
Polishing is carried out to the outer surface of the plug of step a until the outer surface of plug reaches crude state；Step c, the core after polishing
The outer surface of stick coats one layer of swelling binder, then plug is placed into oven and is toasted, and baking time is 20 minutes, oven temperature
Degree reaches 70 DEG C；Step d, the plug for being coated with swelling binder are placed into the cross silicone rubber jacket mold of extruding machine, are squeezed
Chartered plane extrudes out silicone rubber jacket in the outer surface of plug, then is placed into the plug for extruding out silicone rubber jacket is secondary in oven
It is toasted, baking time is 2-3 hours, and oven temperature reaches 200 DEG C；Step e: the plug after step d baking is transferred to
In the injection molding of injector, the full skirt of composite insulator, injection molding temperature are projected by injector integrated injection are as follows: 200 DEG C,
The injection molding sealed time is not less than 10 minutes, removes composite insulator after the completion of injection, completes entire composite insulator
Production.
Beneficial effects of the present invention: the Novel combined insulator of the application, compared with prior art, silicone rubber jacket passes through
The mode extruded is fixed on the outer surface of plug and full skirt is fixed on the outer surface of silicone rubber jacket by way of injection,
To make between silicone rubber jacket and plug it is be bonded it is stronger, more resistant to aging, reduce many places interface and generate point, tide can be prevented
Gas, acid, lye penetrate into plug, corrode plug, thus greatly reduce product and use operation risk；
Silicon rubber can be improved using mode is extruded in a kind of production technology of composite insulator of the application, silicone rubber jacket
Sheath and plug adhesive effect, avoid hurting when stage injection stick and polishing plug for a long time the exposed moisture absorption, pickup the disadvantages of, eliminate
Product runs hidden danger, and full skirt takes injection system, avoids the shortcomings that string umbrella cracky is fallen, ensure that product longtime running
The creepage distance of Shi Suoxu.
