Abstract
The utility model relates to a novel thermal-contraction material composite wall-penetration sleeve, in stead of using an umbrella tower structure of porcelain bushing combination, the utility model adopts a heat shrinking insulation material and a core rod to make an integreated insulation umbrella tower and a lower support rod part; meanwhile, the radial dimension of an insulating jacket is reduced, the insulation umbrella tower and the core rod can be integrated into one body by a heat shrinking method, so that the radial dimension of a current transformer can be tremendously reduced under the condition of the same magnetic flux, and the consumable materials can be largely saved. Compared with the prior 25 KV ceramic sleeve for engine top, the utility model has the advantages of a small footprint, light weight, stable performance, pollution resistance, anti-aging performance, etc.
Description
The utility model belongs to a kind of rolling stock power supply insulating element that is installed on roof.Be mainly used in from the electrical network power taking and introduce electric component in the car.
Locomotive or vehicle are sent in the car by a wall bushing after obtaining electricity by pantograph from the electrical network, and wall bushing had both played to be sent into the fax of pantograph in the car, plays a part again and the roof insulation protection.Existing roof wall bushing all is to adopt insulator as insulating sheath.Though the protective jacket of this porcelain has the insulation characterisitic stable properties, but for the locomotive that moves, but many weak points had; First insulator structure has bulky, the defective that own wt is heavy, but also will cause the structure of the current transformer that matches with it also huge thereupon, consumptive material increases; It two is insulator structures because the fragility of porcelain itself, therefore frangible, this locomotive or vehicle for motion also seems and is far from suitable, because locomotive or vehicle are the mechanisms that is in high-speed cruising, its strong vibrations are can hardly be avoided, and insulator is in this strong vibration environment, chipping caning hardly be avoided, therefore can occur causing decreasing insulating, the corona heating occur, burn out the phenomenon of cover through walls because of the insulator part shakes to encircle; Device too heavily is unfavorable for the loss of weight of rolling stock simultaneously, so the existing wall bushing utmost point remains to be improved.
The purpose of this utility model is: at the deficiency of existing rolling stock wall bushing, it is little to propose the strong volume structure of a kind of insulation property, the compound wall bushing of novel material contracting with heat of good anti-vibration.
The purpose of this utility model realizes by a kind of like this invention technical conceive, the umbrella tower structure of cancellation insulator combination, adopt hot shortness's insulating material and plug integral manufacturing insulated umbrella tower and lower supporting pole portion, dwindle the insulating case radial dimension simultaneously, insulated umbrella tower and plug are made it the compound one that is by pyrocondensation, thereby under the situation that guarantees common flux, can dwindle the radial dimension of current transformer greatly, save a large amount of consumptive materials.
This novel material contracting with heat Compound Insulation Wall Bushing is compared with existing locomotive roof 25KV porcelain bushing, has tangible characteristics.At first it is to adopt novel pyrocondensation series material, replaces original ceramic material, makes Compound Insulation Wall Bushing, and it is little to have a volume, light weight, advantage such as stable performance, anti-soil dodge, anti-aging.Secondly after making insulating sheath with material contracting with heat, can reduce its radial dimension greatly, thereby can reduce the radial dimension of current transformer greatly, made new type current transformer in high voltage (TBL3 type) under the condition that guarantees common flux, replace the existing power locomotive, TBL1 type current transformer on the motor-car, not only save material, volume-diminished, weight is reduced to original below 50%, and has a stable performance, it is strong that anti-soil dodges ability, operating temperature range big (40C～+ 125 ℃), not long (not brokenly not splitting of life-span, aging life-span 20 years) good characteristics.
Therefore this novel material contracting with heat Compound Insulation Wall Bushing and the various high and low pressure current transformers made thereof have novelty, creativeness; Being suitable on electric locomotive, motor train unit, power supply detection vehicle and the similar vehicles etc., overhead wire 25KV high-tension electricity is introduced in the car, is a kind of product of update, has practicality and application prospect widely.
The utility model will be further described below by drawings and Examples:
Fig. 1 is the utility model structural representation.
Among the figure: 1. 11. times wiring poles of fixed head 2. insulation paper washer 3. 4. secondary coil 5. outer tubes, 6. plug 7. conductive copper bars, 8. high pressure umbrella tower 9. mounting flanges, 10. connection bolts unshakable in one's determination insulating sleeve.
Accompanying drawing has provided an embodiment of the present utility model, the utility model comprises the umbrella tower section as can be seen from accompanying drawing, current transformer part and three parts of following wiring pole, the umbrella tower section comprises conductive copper bar 7, plug 6 and umbrella tower 8 several parts, the current transformer part comprises secondary coil 4 again, outer tube 5, unshakable in one's determination 3, insulation paper washer 2, fixed head 1 and mounting flange 9 several parts, following wiring pole part then comprises binding post 10, insulating sleeve 11 and plug 6, conductive copper bar 7 several parts, it is characterized in that: described umbrella tower 8 and following wiring pole insulating sleeve 11 are by the machine-shaping of hot shortness's insulating material, and together be combined with each other with plug 7, constitute an assembly of combining closely.Umbrella tower 8 is combined into one by pyrocondensation processing and plug 7 by hot shortness's cross-linked polyolefin insulating material, simultaneously umbrella tower 8 is a commaterial with following wiring pole insulating sleeve 11, and together is combined with each other with plug 7.
