The invention discloses an electric locomotive top insulating material cover which comprises an insulating material composite layer arranged on a pantograph mounting area and the surrounding area of the pantograph mounting area, a pantograph mounting seat is embedded in the insulating material composite layer, and gaskets are embedded in the periphery of the insulating material composite layer. The lightning impulse resistance testing voltage U1 of the insulating material composite layer is equal to 243+/-10kV, and the testing voltage U2 of a power-frequency voltage-withstand test is equal to 94+/-5kV. The insulating material composite layer comprises an upper insulating material composite layer and a lower insulating material composite layer which are formed in a vacuum integrated mode. The electric locomotive top insulating material cover is attractive in appearance, good in integral coordination performance and good in electric conductivity of a contact face with an electric locomotive top metal cover. The electric locomotive top insulating material cover is fixed on the electric locomotive top metal cover, when the pantograph is electrified, static electricity or corona under the top insulating material cover can be eliminated.
Description
Technical field
The invention belongs to technical field of vehicle manufacture, be specifically related to a kind of electric locomotive top insulating material top cover and preparation method thereof.
Background technology
At present, be loaded on the top cover at electric locomotive top, the flashover phenomenon of roof often occurs in operational process, particularly, near the pantograph supporting insulator, due to the restriction of height, and the top cover wedge angle of installation pantograph is more, the phenomenon of roof high pressure to the electric discharge of top cover wedge angle often appears, cause top cover by high-voltage electric injury, even punched, repair very difficult.The height of China's pantograph supporting insulator is 315mm and 400mm at present, is mainly to have limited the height of contact system due to reasons such as tunnels, makes the height of locomotive be restricted, and the locomotive flashover fault often occurs.Once the accidents such as flashover occur, will directly cause contact system power failure, locomotive rescue, upset the railway transportation order, cause the tremendous economic loss.In highlands, because height above sea level is higher, according to the requirement of height above sea level correction, electric insulating is multiplied by corresponding height above sea level coefficient of correction, the safe operation of guarantee locomotive apart from needs in addition.The top cover generally mainly be welded by skeleton and equipment mount pad.The shortcoming of the cap structure be made by welding process is: the casting coping insulating power are not high, the easy climate impact in commissure easily produces oxidation, the phenomenon of getting rusty, cause top cover drainage to occur in the rainy day, when electric locomotive on plateau, during the operation of the region that rainy, haze weather is common, insulating power can obviously reduce.Thereby design a kind of electric locomotive top insulating material top cover, and research and develop a kind of technique for preparing this kind of insulating top cover and seem of far-reaching significance.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, and a kind of electric locomotive top insulating material top cover and preparation method thereof is provided.
In order to achieve the above object, technical scheme provided by the invention is:

The method of above-mentioned insulating material top cover comprises the steps:
(1) by insulating material-0.1
+0.05MPa the vacuum technology condition under carry out global formation, form insulating material composite bed upper strata;
(2) pantograph mount pad and pad are bonded to the bottom surface on insulating material composite bed upper strata by lining cement;
(3) adhere to insulating material in the bottom surface on the insulating material composite bed upper strata of processing through step (2), and-0.1
+0.05MPa the vacuum technology condition under carry out global formation for the second time, form and to there is upper and lower two-layer insulating material composite bed.
Below in conjunction with principle of design, the invention will be further described:
At first, go out to meet by computer Simulation calculation the insulation material layer that insulating power require; Carry out the checking of laying thickness and dielectric test checking by test again; Then insulating material is carried out to global formation by vacuum technology, form the insulation material layer upper strata; Mount pad and pad that pantograph is installed are bonded to insulating material composite bed upper layer undersurface by lining cement, guarantee that adhesive agent smears evenly and the gap of mount pad and pad and insulating material interlayer is filled up, this is most critical, the effect of pad is the insulating material intensity of top cap of strengthening the mounting hole place, insulating material top cover cracking while avoiding installing; Insulating material is attached to through the bottom surface on the insulating material composite bed upper strata of aforementioned step process, and carries out global formation by vacuum technology, form and there is upper and lower two-layer insulating material composite bed.Can reach the product engineering requirement fully after processing finally by paint.That is, insulating material top cover of the present invention is that insulation material layer is carried out to global formation at twice, by bonding mount pad and the pad that pantograph will be installed of lining cement, is embedded in the composite structure formed between the two layers of insulation material layer.The insulating material composite bed is the vacuum global formation, and its whole position is corresponding with the casting coping position at electric locomotive top.Testing tension U2=94 ± the 5kV of the anti-lightning impulse test voltage U of insulating material composite bed 1=243 ± 10kV, power frequency withstand test.This performance has met electric locomotive on plateau, during the operation of rainy, haze weather is common region, guarantees the safe operation of locomotive.
In the present invention, pantograph mount pad upper surface, higher than insulating material composite bed upper surface 10 ± 0.5mm, is in order to guarantee the planeness of pantograph attachment face.
Described insulating material composite bed (insulating effect) thickness is 15
+0.5mm, be the performance of the testing tension in order to guarantee the voltage of anti-lightning impulse test the, power frequency withstand test.
On described insulating material composite bed, the diameter of the position corresponding with pantograph mount pad profile is 418
+0.5mm, be not interfere phenomenon when guaranteeing that the insulating material top cover is installed on casting coping.
The mount pad of the global formation that critical technological point of the present invention is insulation material layer and insulation material layer and installation pantograph and the composite molding of pad, should guarantee insulating power and the intensity of insulation material layer, prevent from again installing the mount pad of pantograph and peeling off and sealing of pad and insulation material layer, the present invention adopts vacuum technology+adhesive technology just, has guaranteed insulating power and the intensity of insulation material layer and the mount pad of pantograph and combined strength bination and the sealing of pad and insulation material layer are installed.Product of the present invention meets design and actual behavior requirement, without dropping into large-scale tooling device, can realize processing, easily operates moulding, reach insulating effect fully, simultaneously, good looking appearance after paint is processed, total tune is good, with electric locomotive top metal top cover contact surface, conducts electricity very well.Be fixed on electric locomotive top metal top cover, while making the pantograph energising, eliminate static or the corona (this performance is to meet by brushing conduction enamelled coating on the contact surface at insulating top cover and casting coping) of insulating top cover below.
