Description
Technical field
The present invention relates to motor-car field, more particularly to a kind of motor-car car roof composite insulator with anti-soil full skirt.
Background technology
As operation was opened in first high-speed railway Japan Tokaido the Shinkansen on October 1st, 1964 in the world, at a high speed
The development of EMUs is increasingly extensive.By the continuous development in more than 40 years, basically form by modern architecture in Japan, German ICE and method
State TGV is the three big technical system of EMU of representative.Various countries' EMUs are with their own characteristics from respective country's be actually needed,
Development to world's high-speed railway has served very positive.
France puts forth effort since 1976 to study TGV-PSE, is come into operation in September, 1981.May nineteen ninety, TGV-
A325 cars group reaches operation speed per hour 515.3km in Atlantic Ocean line, creates the world record of wheel rail system road speed.2007
On April 3, in, French tests EMUs V150 test speeds reach 574.8km/h, create high-speed railway speed new record.
Federal railway express instruction carriage between nineteen eighty-two August trial-production ICE cities.1985, using 2 dynamic 3 ICE/V for dragging form
Type experiment EMU is successfully manufactured experimently, and reaches 317km/h test speed.In May, 1988, ICE/V type test trains are in the Chinese
406.9km/h speed record is created between Nowe-Wei Ercibao.
The Ministry of Railway of the People's Republic of China, MOR was by first backward Canadian Pang Badi, Kawasaki, Japan heavy industry, France in 2004
The foreign enterprises such as Alstom, Siemens buy high-speed railway vehicle technology, with Importing Foreign Advanced Technology and inhale
The mode of receipts, by under Chinese Bei Che groups and South China car group vehicle manufacture enterprise produce, develop the km of speed per hour 350 and
Above bullet train.
And one of the visual plant of insulator as roof circuit safe operation, its technical performance obtain electric locomotive operation
Department and manufacturing common concern.The high speed development of China's power network promotes the rapid growth of composite insulator industry, makes me
State's silicon rubber compound insulator manufacturing technology occupies first place in the world.
Rough Statistics, national composite insulator manufacturing enterprise is more than 100, but the enterprise for accounting for leading market only has more than 10
Family.The insulator manufacturing enterprise for being engaged in railway security transport simultaneously is even more very few.With train speed rapid raising and
The extensive laying of electric railway, the working environment of top insulation are more diversified, it is desirable to harsher.Insulator in recent years
Flashover trip accident tends to be frequent and severe.
But the ratio of slope of the upper and lower surface of the full skirt of motor-car car roof composite insulator of the prior art compared with
Slow, stain resistance is poor, and particularly under dynamic environment, contamination accumulation characteristics are poor, it is impossible to the cleaning of product surface is effectively ensured,
The occurrence of easily causing pollution flashover, particularly motor-car are in safe operation under the conditions of high wind speed, more intensive umbrella skirt construction
Rainwater is linked to be chain easily under heavy rain or heavy rain for design, causes rain to dodge.
For problem above, need badly and want a kind of motor-car car roof composite insulator with anti-soil full skirt, to solve existing skill
Present in art the problem of motor-car car roof composite insulator stain resistance difference.

Some groups of axially aligned full skirts 22 are provided with, the upper surface of full skirt 22 is relative to the inclination angle of supporter radial section
8.5 degree to 9.5 degree, the full skirt lower surface is -0.8 degree to -1.2 degree relative to the inclination angle of supporter radial section.
In the present embodiment, the side wall of supporter 21 is provided with full skirt 22 described in axially aligned 5 groups.
In the present embodiment, as further preferably, the upper surface of full skirt 23 is relative to supporter radial section
Inclination angle is 9 degree, and the lower surface of full skirt 23 is -1 degree relative to the inclination angle of supporter radial section.
Due to can effectively prevent from dodging compared with rain along using 9 degree of angles, the degree of lower edge use -1 angle on full skirt 22;Under dynamic environment,
There are good contamination accumulation characteristics, the cleaning of product surface is effectively ensured, there is the generation for preventing pollution flashover, be completely suitable for motor-car in high wind
Safe operation under the conditions of speed.Preventing more intensive umbrella skirt construction from designing simultaneously, rainwater is linked to be chain easily under heavy rain or heavy rain
Shape, rain is caused to dodge.
In the present embodiment, preferably, the supporter 21 is high-strength glass fibre epoxy resin rod.
The supporter 21 is the skeleton of composite insulator, because this programme is using high-strength glass fibre epoxy resin rod work
For supporter 21, so having preferable acid-resistant property and high transverse property, bending resistance is more than 16kN.
New body material glass fiber epoxy resin dipping high temperature winding, it bears mechanical stress, electric stress, sulfur hexafluoride simultaneously
And its chemical action of analyte, the moisture in air may be entered internal due to design defect, mass defect etc., make glass fibers
Dimension reinforced epoxy pipe deteriorates.Also, the coefficient of expansion of glass fiber reinforced epoxy resin pipe is close to zero, and metal
The coefficient of expansion of annex is 0.26 × 10-6Although both differ very little, gas is all-pervasive, in order to ensure product out of doors
End accessory, glass fiber reinforced epoxy resin pipe are can guarantee that when the reliability and security of longtime running, design and manufacture
Interface connection and sealed reliable with umbrella cover.
In the present embodiment, the upper end of the supporter 21 is provided with the upper gold utensil 23 for connecting conducting rod, it is described on
Gold utensil 23 is assemblied in the upper end of the supporter 21 by way of high pressure crimping.

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 can also form the silicon of insulation, so its electrical insulating property is excellent.
Because the bond energy of silicon rubber is high, chemical stability is good, so its heat resistance is better than organic polymer.Furthermore by
Weak in intermolecular interaction, so glass transition temperature is low, cold resistance might as well.Therefore, any area on earth uses,
Its characteristic is all without change.Because the surface of polysiloxanes is methyl group, so it has hydrophobicity, thus can be used for preventing
Water.This product outer insulating material uses high quality silicon rubber, acid and alkali resistance, salt characteristic, has excellent anti-atmospheric aging and ultraviolet
Line ageing properties.Temperature is practical, high temperature resistant, can be worked at 100 DEG C;It is low temperature resistant, elasticity is still kept at -60 DEG C.
In the present embodiment, preferably, the outside of the full skirt 22 is provided with umbrella cover.In order to eliminate because of bonding and
Existing interior insulation hidden danger, improves interior insulation intensity, and the full skirt 22 is structure as a whole with the umbrella cover.
In the present embodiment, between the lower shirt rim of motor-car car roof composite insulator and its lower gold utensil 24 under harsh weather
Electric discharge problem, if also need to increase creep distance, creeping-increasing skirt 26 can be provided with the lower gold utensil 24 of the lower end of supporter 21.
On the premise of product height is not increased, arcing distance and insulator creep age distance are substantially increased, is thoroughly solved
Electric discharge problem of the shirt rim to base under insulator, makes the insulation margin of product bigger, safety and reliability.
In the present embodiment, preferably, the creeping-increasing skirt upper surface relative to supporter radial section inclination
