Abstract
The utility model discloses a surge-preventing electric reactor which comprises a metal body, wherein the metal body comprises a connecting part and an electromagnetic part with an electromagnetic coil winding, a polyimide film layer is lapped on the periphery of the electromagnetic coil winding of the metal body, and a flexible jacket is arranged on the outer surface of the polyimide film layer. The surge-preventing electric reactor has the advantages of good insulation effect, high reliability and the like.
Description
Technical field
The utility model relates to a kind of reactor, is specifically related to a kind of anti-surge reactor that is used for locomotive or EMUs roof.
Background technology
The anti-surge reactor of the utility model generally is mounted on the roof of locomotive or EMUs; Its major function is the closed instantaneous high pressure that produces with the moment of turn-offing of main vacuum circuit-breaker that absorbs roof, thus main transformer, trailer system and the secondary power system of protection locomotive or EMUs.The wrapped laminated polyester film of solenoid winding periphery of the metal body of external anti-surge reactor, the outer surface of laminated polyester film is through the adhering with epoxy resin glass tape.The anti-surge reactor of this structure, during high-speed cruising, air-flow has souring to its windward side under harsh running environment; Form the low pressure vortex at lee face; Reeling off raw silk from cocoons, peeling off appears in glass tape easily like this, and perhaps the very fast disrepair phenomenon of ageing of insulation and insulation makes insulation effect poor; Reliability is low, brings very burden to maintenance.
Summary of the invention
The purpose of the utility model is, provides a kind of not only insulation effect good, and the high anti-surge reactor of reliability.
In order to achieve the above object; The technical scheme of the utility model is: a kind of anti-surge reactor; Comprise metal body; Said metal body comprises connecting portion and has an electromagnetic portion of solenoid winding, and its: the solenoid winding periphery of said metal body is surrounded with polyimide film layer, and said polyimide film layer outer surface has flexible shroud.
In above-mentioned technical scheme, there is the silica gel firming body at the two ends of said polyimide film layer and flexible shroud.
In above-mentioned technical scheme, said flexible shroud is the vulcanized rubber sheath.But be not limited to this.Also can adopt flexiplast sheath or rubber and plastic sheath.
In above-mentioned technical scheme, the THICKNESS CONTROL of said polyimide film layer is in 0.76mm ~ 1.2mm scope.And the thickness of said polyimide film is 0.19mm.
The good effect that the utility model had is: because the solenoid winding periphery of the metal body of the reactor of the utility model is surrounded with polyimide film layer; And advantage such as that polyimide film layer has is high temperature resistant, radiation hardness, resistance to chemical attack and electrical insulation capability are good; Can be used for having good insulation performance property, reliability height on the anti-surge reactor, and flexible shroud arranged in the medium-term and long-term use of 250～280 ℃ of air at said polyimide film layer outer surface; Not only effectively protected polyimide film layer; And if flexible shroud is aging or cracking after, be convenient to change, for maintenance work brought convenient.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is described further, but is not limited to this.
As shown in Figure 1; A kind of anti-surge reactor; Comprise metal body 1; Said metal body 1 comprises connecting portion 1-1 and the electromagnetic portion 1-2 with solenoid winding 1-2-1, and its: the solenoid winding 1-2-1 periphery of said metal body 1 is surrounded with polyimide film layer 2, and said polyimide film layer 2 outer surfaces have flexible shroud 3.
As shown in Figure 1, in order to make the anti-surge reactor of the utility model have dustproof, waterproof and etch-proof effect, there is silica gel firming body 4 at the two ends of said polyimide film layer 2 and flexible shroud 3.
As shown in Figure 1, for the ease of changing and safeguarding flexible shroud, said flexible shroud 3 is the vulcanized rubber sheath.
The THICKNESS CONTROL of said polyimide film layer 2 is in 0.76mm ~ 1.2mm scope.The thickness of the polyimide film of the utility model is 0.19mm.
The polyimide film of the utility model comprises two types of equal benzene type polyimide film and biphenyl polyimide films; Preferentially select for use by du pont company, the corona-resistant polyimide film of ProductName Kapton FCR has outstanding high temperature resistant, radiation hardness, resistance to chemical attack and electrical insulation capability; Can be in the medium-term and long-term use of 250～280 ℃ of air; Vitrification point is 385 ℃, and hot strength is 200MPa in the time of 20 ℃, in the time of 200 ℃ greater than 100MPa.
The utility model lab scale effect shows that the comparable prior art of the utility model has better insulating properties and reliability advantages of higher.
