Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
Fig. 1 is the cutaway view that the motor-car roof anti-soil that provides of the utility model device embodiment dodges composite insulator.As shown in Figure 1, motor-car roof anti-soil dodges composite insulator, comprise supporter 21, around described supporter 21 sidewalls, be provided with the some groups of full skirts 22 that are arranged side by side vertically, described full skirt 22 radially outwards protrudes from described supporter 21 sidewalls, topmost the upper end of full skirt 22 is provided with gold utensil 23, the lower end of full skirt 22 is provided with lower gold utensil 24 bottom, creepage distance described in it between upper gold utensil 23 and lower gold utensil 24 is 1085mm-1095mm, and it is 245mm-255mm that the arc between upper gold utensil 23 and lower gold utensil 24 dodges distance.
In the present embodiment, as further preferred version, the creepage distance between described upper gold utensil 23 and lower gold utensil 24 is 1090mm, and it is 250mm that the arc between upper gold utensil 23 and lower gold utensil 24 dodges distance.
In the present embodiment, because structural design aspect adopts long creepagely than apart from (1090cm/25kV), under identical filthy condition, have than the porcelain insulator of the identical creep distance above good anti-soil that doubles and dodge ability.
In the present embodiment, 4 full skirts 22 that are positioned at upper end are comprised of a gamp and a umbellule respectively, and the one group of full skirt 22 being positioned at is bottom comprised of two umbellules.
In the present embodiment, described supporter 21 is high-strength glass fibre epoxy resin rod.
The skeleton that described supporter 21 is composite insulator, because this programme adopts high-strength glass fibre epoxy resin rod as supporter 21, so have good high transverse property, bending resistance is greater than 16kN.
New body material glass fiber epoxy resin dipping high temperature is wound around, it bears the chemical action of mechanical stress, electric stress, sulphur hexafluoride and analyte thereof simultaneously, moisture in atmosphere may enter inside due to design defect, mass defect etc., glass fiber reinforced epoxy resin pipe is occurred deteriorated.And the coefficient of expansion of glass fiber reinforced epoxy resin pipe is close to zero, and the coefficient of expansion of metal-ware is 0.26 * 10
-6although both differ very little, gas is all-pervasive, in order to guarantee the product reliability and security of long-time running out of doors, wants the interface that can guarantee end accessory, glass fiber reinforced epoxy resin pipe and umbrella cover connect and seal reliable during Design and manufacture.
In the present embodiment, the upper end of described supporter 21 is provided with for connecting the upper gold utensil 23 of conducting rod, and described upper gold utensil 23 is assemblied in the upper end of described supporter 21 by the mode of special equipment annular crimping.
And the lower end of described supporter 21 is provided with for described composite insulator being arranged on to the lower gold utensil 24 on motor-car roof, described lower gold utensil 24 is assemblied in the lower end of described supporter 21 by the mode of special equipment annular crimping.
Concrete, the top and bottom of described supporter 21 are respectively equipped with upper end open and lower ending opening, and described upper gold utensil 23 and lower gold utensil 24 insert respectively described upper end open and lower ending opening and then be assemblied in the two ends of described supporter 21.
In the present embodiment, owing to being positioned at the gold utensil at described supporter two ends Shang Xia 21, all adopt the mode of special equipment annular compression to assemble, so bending resistance composite insulator is connected firmly, there is good anti-seismic performance, anti-impact force performance and anti-brittle failure performance, bending resistance is greater than 16kN, can under various weathers, operating mode, environment, move.
In the present embodiment, as preferred version, described upper gold utensil 23 is made by stainless steel 304.
In the present embodiment, as further preferred version, described lower gold utensil 24 is also made by stainless steel 304.
In the present embodiment, as preferred version, described full skirt 22 is positioned at the outside of umbrella cover.In order to eliminate the interior insulation hidden danger existing because of bonding, dielectric strength in improving, described full skirt 22 is structure as a whole with described umbrella cover.
In the present embodiment, as preferred version, described full skirt 22 is made by silastic material.
Silicon rubber has surface can be low, hydrophobicity is strong and the characteristic such as migration of hydrophobicity, makes it have particularly preferred anti-soil and dodge performance.Carbon number in silicon rubber molecule is fewer than organic polymer, so its arc resistance, resistance to leakage property are very good.In addition, even if burning also can form the silicon of insulation, so its electrical insulating property is excellent.
Because the bond energy of silicon rubber is high, chemical stability good, so its thermal endurance is better than organic polymer.Moreover a little less than intermolecular interaction, so vitrification point is low, cold resistance might as well.Therefore, any area is on earth used, and its characteristic can not change.Because the surface of polysiloxanes is methyl group, so it has hydrophobicity, thereby can be used for waterproof.This product outer insulating material adopts high-quality silicon rubber, and acid and alkali resistance, salt characteristic have excellent anti-atmospheric aging and ultraviolet ray ageing performance.Temperature is practical, high temperature resistant, can at 100 ℃, work; Low temperature resistant, at-60 ℃, still keep elasticity.
In the present embodiment, for 24 electric discharge problems under harsh weather of the lower shirt rim of motor-car car roof composite insulator and its lower gold utensil, if also need to increase creep distance, can on the lower gold utensil 24 of described supporter 21 lower ends, be provided with creeping-increasing skirt 26.
Do not increasing under the prerequisite of product height, greatly improving arcing distance and insulator creepage distance, thoroughly solving the electric discharge problem of shirt rim to base under insulator, making the insulation margin of product larger, safety and reliability.
In the present embodiment, as preferred version, described creeping-increasing skirt 26 is Split type structure with lower gold utensil 24, is installed on lower gold utensil 24, but is not former configuration when operation, can not affect steep wave test.As further preferred version, described creeping-increasing skirt 26 is selected material contracting with heat manufacture.
In the present embodiment, as another kind of preferred version, described creeping-increasing skirt 26 directly vulcanizes on described lower gold utensil 24.
In the present embodiment, as preferred version, the diameter of described creeping-increasing skirt 26 is 80mm-90mm.
The advantages such as this product has that quality is light, volume is little, is convenient to transportation and installation, mechanical strength is high and resistance to pollution performance is good, are in operation simultaneously and can, in order to avoid preventative test is exempted from cleaning, can avoid pollution flashover accident.Being specially adapted to medium above filthy area uses.Adopting creeping-increasing skirt utility model patent technology simultaneously, effectively extended insulator arcing distance under the prerequisite that does not increase product height, is a kind of novel insulator that is different from porcelain insulator from material to structure completely.There is the advantages such as rational in infrastructure and high speed performance is good.Product has passed through 380 kilometers/hour of wind tunnel tests of Low Speed Aerodynamic Institute of Chinese Aerodynamic Research and Development.These series of products are applicable to CRH3 series motor train unit.
Know-why of the present utility model has below been described in conjunction with specific embodiments.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection range.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, within these modes all will fall into protection range of the present utility model.
