Abstract
The utility model relates to a post insulator flange for an air reactor. A gap internally filled with insulation strips is formed in the flange, and the exterior of the flange is fixed through epoxy yarns. The width of the gap ranges from 4 mm to 5 mm. The post insulator flange has the advantages that the gap is reserved in the flange, the insulating materials are added into the gap, a vortex path is cut off, heating of a post insulator structural member is avoided, and additional losses of the air reactor are reduced.
Description
Technical field
The utility model relates to air core reactor field, relates in particular to a kind of post insulator flange for air core reactor.
Background technology
In prior art, air core reactor adopt over the ground or alternate post insulator, the structure of this post insulator is that mid portion is porcelain vase, two ends mounting flange, flange is aluminium alloy or stainless steel, sees Fig. 1.In the time that air core reactor moves, under action of alternating magnetic field, post insulator flange can produce eddy current, and the very large eddy current loss of generation, make post insulator metal flange for a long time in superheat state, cause the degradations such as its machinery, weatherability, be unfavorable for the long-term stability operation of reactor.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of post insulator flange for air core reactor, do not reducing under the prerequisite of flange mechanical strength, cut off eddy current path, solve large capacity air core reactor and cause the overheated problem of post insulator flange because of magnetic field and eddy current.
For achieving the above object, the utility model is achieved through the following technical solutions:
For a post insulator flange for air core reactor, inner gap of filling insulation strip is set on described flange, flange outside is fixed by epoxy yarn.
Described gap width is 4-5mm.
Compared with prior art, the beneficial effects of the utility model are:
Gap is set in flange, and in gap, adds insulating material, cut off eddy current path, avoided the heating of post insulator structural member; The supplementary load loss of air core reactor are reduced.
Accompanying drawing explanation
Fig. 1 is the structural representation of post insulator.
Fig. 2 is front view of the present utility model.
Fig. 3 is the cutaway view of Fig. 2 along A-A line.
In figure: 1-flange 2-porcelain vase 3-epoxy yarn 4-insulation strip 5-gap.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following execution mode.
See Fig. 2, Fig. 3, a kind of post insulator flange for air core reactor, arranges inner gap 5 of filling insulation strip 4 on described flange 1, and flange 1 is outside fixing by epoxy yarn 3.
Embodiment: the all-metal flange 1 of post insulator is divided into some deciles vertically, open the gap 5 of 4～5mm in incision, with after insulation strip 4 blinds 5, at the peripheral epoxy yarn 3 that is wound around of flange 1, finally, after solidifying, make its Shu Weiyi entirety, now, flange 1 is in the situation that other performances are almost constant, reduced the induced potential of every part metals part, thereby reduced eddy current, eddy current loss reduces greatly.
The utility model has improved the overheated situation of air core reactor B-C post insulator, reduces the supplementary load loss of air core reactor simultaneously.Reduce the structural member of air core reactor for dispelling the heat, reduce product cost, improve mechanical strength and the resistance to overturning of product.
Claims (2)
1. for a post insulator flange for air core reactor, it is characterized in that, inner gap of filling insulation strip is set on described flange, and flange outside is fixed by epoxy yarn.
2. a kind of post insulator flange for air core reactor according to claim 1, is characterized in that, described gap width is 4-5mm.
