Specific implementation mode
Below in conjunction with the attached drawing specific implementation mode that the present invention will be described in detail.
See that Fig. 1, the present invention include anti-birds droppings grading ring 1, hard sheath 2, hard full skirt 3, silicon rubber umbrella skirt 4,5 and of plug
Gold utensil 6.
As shown in Fig. 2, the anti-birds droppings grading ring 1 is closed circle structure, and inside is the grading ring sheet of metal material
Body 101, outside are hard full skirt sides 102, and full skirt side is more than grading ring ontology, increases grading ring overall dimensions, expand anti-
Range is protected, birds droppings shielded area is improved, hinders birds droppings to fall, achievees the purpose that anti-birds droppings.
Hard full skirt 3 totally 2, each 1 of insulator high and low pressure side, 3 groups of integral, alicyclic rings of hard sheath 2 and hard full skirt
Race's epoxy resin or polyolefin material are matrix, are aided with methyl hexahydrophthalic anhydride curing agent, aluminum trihydrate micro mist fire retardant, silanization
Coupling filler, accelerating agent, fluorine compounds auxiliary agent etc. are made.Have the characteristics that high rigidity, shock resistance, resistance to electric arc, anti-unfirmly closing, it can
Prevent composite insulator height pressure side by birds, in case full skirt is by destruction and then causes flashover fault.
The hard full skirt 3 is made of hard big full skirt 301 and the small full skirt of hard 302, and hard big full skirt 301 is mounted on hard
The low-pressure end of matter composite insulator, the small full skirt 302 of hard are mounted on the high-pressure side of hard composite insulator, wherein the hard
Big full skirt 301 refers to the diameter that its full skirt diameter is more than the silicon rubber umbrella skirt 4 at position among hard composite insulator, the hard
Small full skirt 301 refers to that 4 diameter of silicon rubber umbrella skirt at position among its full skirt diameter and hard composite insulator is identical.
Meanwhile hard big full skirt 301 coordinates anti-birds droppings grading ring 1, plays the role of dual anti-birds droppings, and birds droppings is hindered to fall
To silicon rubber umbrella skirt, in case so that full skirt is contaminated causes birds droppings flashover fault.
Except height pressure side hard full skirt 3, silicon rubber umbrella skirt 4 is installed at other positions, and silicon rubber umbrella skirt 4 is by materials such as silicon rubber
It is made, has the characteristics that strong hydrophobicity, resistance to pollution flashover, electrical erosion resistance.
5 height pressure side of plug wraps up hard sheath 2, to play the role of insulation and sealing.Hard full skirt 3 and silicon rubber umbrella
Skirt 4 is by the process Installation of squeezing bag penetrating umbrella or vacuum injection in 1 outside of hard sheath.
Hard full skirt and sheath have more excellent anti-uv-ray and weatherability compared to silicon rubber umbrella skirt and sheath
Can, it can be kept under severe application environment；There is very high temperature tolerance and good corrosion resistance simultaneously, be suitable for family
Outer use；And have the characteristics that high rigidity, shock resistance, anti-unfirmly closing, composite insulator height pressure side full skirt can be prevented by birds
It pecks at.
Silicon rubber umbrella skirt and sheath have more excellent hydrophobicity and migration of hydrophobicity special compared to hard big full skirt and sheath
Property, resistance to pollution flashover and wet sudden strain of a muscle performance, can keep sufficiently high external insulation performance under the conditions ofs filth, rainwater etc..Auxiliary is with hard
Big full skirt and sheath meet the performance of anti-unfirmly closing, anti-birds droppings while meeting external insulation performance.
Plug 5 is located at penetralia, outer wrapping hard sheath 2, is the load bearing component of composite insulator mechanical load and interior
The major part of insulation；It is made of materials such as glass fibre and epoxy resin, there is excellent mechanical strength, insulation performance and length
Phase stability.Gold utensil 6 is located at 5 both ends of plug, and metal material plays connection and supporting role.
The present invention uses four kinds of umbrella skirt constructions, is isometrical umbrella skirt construction (referring to attached drawing 3), small one and large one umbrella skirt construction respectively
A small umbrella skirt construction in (referring to attached drawing 4), a big two small umbrella skirt construction (referring to attached drawing 5), one big one (referring to attached drawing 6)；It is different
Umbrella skirt construction has an impact the lending analysis of composite insulator, resistant characteristic and self-cleaning characteristic；Compared to isometrical umbrella skirt construction,
Small one and large one, one big two it is small and one big one in a small umbrella skirt construction there is minimum range between the umbrella of bigger, but creepage distance is corresponding
Become smaller；The umbrella diameter of isometrical full skirt is larger, and creepage distance is larger, and insulator contamination voltage is higher, but umbrella diameter increases greatly insulator
Quality and glue consumption, and make insulator contamination degradation, and pollution flashover voltage is with the range that creepage distance increases and improves
It is limited.According to the difference of the environmental condition of insulator installation and operation and gradation for surface pollution, the exhausted of different umbrella skirt constructions can be chosen
Edge, to meet actual needs.
Present invention applicant combines Figure of description to be described in detail and describe the implementation example of the present invention, still
It should be appreciated by those skilled in the art that it is only the preferred embodiments of the invention to implement example above, explanation is only in detail
Help reader more fully understands spirit of that invention, and it is not intended to limit the protection scope of the present invention, on the contrary, any be based on this hair
Any improvement or modification made by bright spirit should all be fallen within the scope and spirit of the invention.
