Description
Technical field
The utility model belongs to electromagnetic field insulation technology field, particularly a kind of magnetic confinement balance bed field coil insulation system.
Background technology
Magnetic confinement balance bed is by field coil externally-applied magnetic field, magnetic catalyst granule to be constrained in reactor, it is uniformly distributed, in the time that the reactive materials such as caprolactam are surperficial by the magnetic catalyst granule in reactor, magnetic catalyst keeps balance and stability under the effect of hydraulic shock power and magnetic attraction, can reduce thus the volume of reaction unit, significantly save the consumption of catalyst.In the prior art, the electromagnetic wire that magnetic confinement balance bed adopts successively coiling forms, the turn-to-turn voltage that the alternating current turn-to-turn voltage that coil first and last circle bears during by field coil will bear higher than other circle coil, therefore coil turn-to-turn short circuit fault mostly occurs at first, last circle.Meanwhile, the field coil of magnetic confinement balance bed, in winding process, easily causes short circuit around between the insulation harm of layer and interlayer, group, and is difficult to find when coiling.
Utility model content
The purpose of this utility model is to provide and a kind ofly can effectively solves the shorted-turn fault that field coil first and last circle easily occurs, and the magnetic confinement balance bed field coil insulation system of short trouble between the interlayer easily causing in winding process, group.
Realizing the technical scheme that the purpose of this utility model takes is: this structure comprises housing and the field coil of magnetic confinement balance bed, wherein, the coiling of field coil adopts the electromagnetic wire that model is SBMYFB-40/155, interior stacking being surrounded by of this electromagnetic wire gathered imines adhesive tape, skin is enclosed with individual layer dacron glass yarn, at the head of field coil, circle place, end is repeatedly surrounded by polyimides adhesive tape, between each layer of field coil, being lined with thickness is the insulation interlayer of the FDMD material of 0.2mm, between each adjacent sets of field coil and between field coil and housing, be all lined with the insulation interlayer that two layers of thickness is the FDMD material that 0.2mm is thick.
The poly-imines adhesive tape of stacking bag in described electromagnetic wire, its thickness is 0.05mm, is coated with F46 thin layer on adhesive tape.
In described electromagnetic wire, the poly-imines adhesive tape of stacking bag adopts 2/3 repeatedly to wrap sintering structure.
The first, last circle place of described field coil is the polyimides adhesive tape of bag repeatedly, and its thickness is 0.06mm, and width is 25mm.
The double-sided insulation gross thickness of described electromagnetic wire is 0.40mm;
The magnetic confinement balance bed field coil insulation system of making according to such scheme, by adopting first, last circle turn-to-turn insulation to strengthen to every the coil that produces magnetic field in magnetic confinement balance bed, in electromagnetic field galvanization, can effectively avoid the generation of first, last circle coil turn-to-turn short circuit fault, guarantee thus the security of operation of magnetic confinement balance bed.And in single group winding process of field coil, between each layer of field coil, adopt layer insulation interval, avoid the generation of layer short circuit fault; Insulation gap between employing group between while every group of coil, has reduced single field coil fault on other field coils impacts, for every group of coil isolated operation provides assurance.
