Abstract
The present invention is a kind of composite hollow insulator, inside and outside be each equipped with the insulating sheath and full skirt of silicon rubber.The advantages of this structure is: the composite hollow insulator is the exterior insulation cooperation for mainly undertaking equipment with outer insulation jacket and full skirt, and it is horizontal that the silicon rubber insulation sheath and full skirt inside core pipe improve internal edge flashing to increase the creepage distance inside core pipe.There is the composite hollow insulator of umbrella sheath that can be used in high voltage isolator and power station supporting insulator etc. inside and outside this, effectively reduce the problem larger by the amount of deflection of the power station composite insulator of solid mandrel production, it is ensured that safe operation of the composite hollow insulator as supporting insulator.
Description
Technical field
The present invention relates to a kind of appliance device, specifically a kind of NEW TYPE OF COMPOSITE power station hollow insulator.
Background technique
The development of State Grid's industry directly affects the economic development in China.In recent years, the development of composite power station insulator
It is more and more extensive, but the composite power station insulator of solid mandrel production constrains it in certain sides since the amount of deflection of plug is larger
The use in face.And the amount of deflection of composite hollow insulator is smaller, thus it is applicable in its fortune in terms of disconnecting switch and power station
With.In order to improve its built-in electrical insulation of interior insulation composite hollow insulator, use at present is oil-filled or fills six-component force balance gas
Mode, but to use it inconvenient for this mode, therefore, develops one kind and is easy to use, does not have to oil-filled or inflation
Insulator product for High-Voltage Electrical Appliances and power station trouble-free operation tool have very important significance.
Summary of the invention
In order to make up the defect of the prior art, the present invention provides a kind of new station insulator, can increase inside climb electricity away from
It is horizontal from internal edge flashing is effectively improved, guarantee the safe operation of insulator.
The purpose of the present invention is achieved through the following technical solutions:
A kind of composite hollow insulator, main body is a hollow epoxy fibreglass winding core pipe, in epoxy fibreglass
Winding core pipe both ends are fixedly installed with metal flange attachment；Epoxy fibreglass winding core pipe outer wall be coated with outer insulation jacket and
Full skirt；Interior insulation sheath and full skirt are equipped in the inner wall fastening of epoxy fibreglass winding core pipe.
The outer insulation jacket and full skirt and interior insulation sheath and full skirt are electrically insulating silicone rubber.
The advantages of structure of the invention, is:
The composite hollow insulator is the exterior insulation cooperation for mainly undertaking equipment, core pipe with outer insulation jacket and full skirt
Internal silicon rubber insulation sheath and full skirt is to the edge flashing that increases the creepage distance inside core pipe to improve inside core pipe
It is horizontal.Due to there is umbrella sheath inside and outside core pipe, inside does not have to oil-filled or inflation, and due to the lesser characteristic of its amount of deflection,
The product can be safely used for high voltage isolator and power station supporting insulator etc., it is ensured that composite hollow insulator
Safe operation as supporting insulator.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
Symbol in figure:
1. metal flange attachment；2. epoxy fibreglass winds core pipe；3. outer insulation jacket and full skirt；4. interior insulation sheath and
Full skirt.
Specific embodiment
Composite hollow insulator of the present invention increases on the basis of former composite hollow insulator basic structure in the inside of core pipe
Add silicone rubber jacket and full skirt, structure as shown in Figure 1:
A kind of composite hollow insulator, main body is a hollow epoxy fibreglass winding core pipe 2, in epoxy fibreglass
Winding 2 both ends of core pipe are fixedly installed with metal flange attachment 1.The outer wall of epoxy fibreglass winding core pipe 2 is coated with external insulation shield
Set and full skirt 3.Innovation structure of the invention are as follows: be equipped with interior insulation sheath in the inner wall fastening of epoxy fibreglass winding core pipe 2
And full skirt 4.
The outer insulation jacket and full skirt 3 and interior insulation sheath and full skirt 4 are that electrically insulating silicone rubber is made.
Composite hollow insulator of the present invention, product structure is reasonable, feasible process, not only economical but also practical.
