Abstract
The invention relates to the field of ultrahigh and extra-high voltage electrical manufacturing, in particular to a glass fiber mixed band transposed conductor with impregnating resin as an insulator. The transposed conductor comprises a transposed conductor band which is composed of multiple single round aluminum wires arranged in multiple layers. An insulated film taped covering is wrapped outside the single round aluminum wires. A composite film insulation layer is wrapped outside the transposed conductor band. A glass fiber mixed band layer is wrapped outside the composite film insulation layer. As a result, the grade of the withstand voltage of the transposed conductor is increased. Moreover, the outermost glass fiber mixed band layer enables the conductor to have better leakproofness, and water and impurities can not easily enter the conductor, so that the electrical performance of an electric reactor is greatly improved, and the probability of a turn-to-turn short circuit is lowered. Tests show that the average withstand voltage of the multi-layer aluminum transposed conductor is over 10000 V, the breakdown voltage is over 26000 V, and therefore the transposed conductor is suitable for the ultrahigh voltage and extra-high voltage field.
Description
Technical field
The present invention relates to super, ultra high voltage Electric Manufacture field, particularly relate to a kind of glass fibre and mix ribbon impregnating resin and make the transposed conductor insulated.
Background technology
In superhigh pressure and extra-high voltage electric transmission and transformation engineering, the winding of various types of reactor and electrical equipment, must tolerate high voltage and very large electric current.Also to consider the loss reducing electric energy simultaneously.
The dry reactor coil used in electrical network, tradition use be all many sub-thread thin film winding round aluminum wires and around.Because the coil diameter of dry reactor is very large, the number of turn is a lot, needs the length of wire to reach a few km.Such multiple conducting wires and around coil in, after coiling multilayer, the length of every root wire and resistance will differ larger.The leakage flux produced in such operation, will produce circulation in wire, causes larger electric energy loss.Add the restriction that aluminum conductor self exists impurity, defect etc. and not easily removes, the reactor of general aluminum conductor coiling, only for being less than the low capacity reactor on 35kV electrical network, can not be used for superhigh pressure and ultra high voltage field.
Some dry reactor coils, adopt many round aluminium bare wires to be twisted into rectangle, skin wraps up inner insulating layer, insulating barrier and composite membrane external insulation layer structure successively.The reactor of this wire coiling, is only applicable to ordinary high pressure electrical network, and still can produce circulation formation eddy current loss in the wire that is in operation.
Dry reactor coil in recent years, employing be many encapsulating strands transposed conductor parallel-connection structures, in the winding process of coil, respectively inside and outside wire respectively around on which floor glass fibre.This structure is the sealing in order to ensure coil, prevents the electric property entering to affect coil of moisture and impurity.Special compound need be added at wire from the extension in encapsulating, to ensure not having gap between the extension of wire and encapsulating, prevent the electric property entering to affect coil of moisture and impurity.And due to the technique for coiling of present coil, the epoxy impregnation glass fibre of parcel wire is the surfaces externally and internally that five strands of yarns or seven strands of yarns are wrapped in wire, the method to result in yarn process very likely outlet gap, is difficult to the seal guaranteeing whole encapsulating structure.In recent years, the multiple Inter-turn Short Circuit Phenomenon major part of dry-type air-core reactor is that the seal caused due to this technique is not enough, and aqueous vapor entered, and coil causes.
Summary of the invention
The object of the invention is to the deficiency overcoming above-mentioned technology, and provide a kind of glass fibre to mix ribbon impregnating resin to make the transposed conductor insulated, use this product coiling reactor winding, the electric property of product can be improved greatly, reliable solution dry-type air-core reactor glass fibre mixes the problem that ribbon impregnating resin does the transposed conductor sealing insulated, under being especially for use in superhigh pressure, ultra high voltage and big current situation.
The present invention for achieving the above object, by the following technical solutions: a kind of glass fibre mixes ribbon impregnating resin and makees the transposed conductor insulated, it is characterized in that: the transposed conductor comprising the multilayer arrangement be made up of many sub-thread circle aluminum steels, described sub-thread circle aluminum steel is coated with insulation film lapping layer; Described transposed conductor is coated with laminated film insulating barrier, and described laminated film insulating barrier is coated with glass fibre and mixes ribbon layer.
Preferably, described laminated film insulating barrier adopts polyester resin film and polyimide film, and carry out stacked package with one deck polyester resin film, one deck polyimide film and one deck polyester resin film coated, packet stack rate is 10-90%.
Preferably, described insulation film lapping layer and glass fibre mix ribbon layer and adopt the stacked helical form of 10%-90% wrapped respectively.
Preferably, described glass fibre mixes the glass fibre non-woven that ribbon layer is impregnating resin.
Preferably, described insulation film lapping layer is polyester film, and packet stack rate is 10-90%.
Preferably, the cross section of described transposed conductor band is square.
The invention has the beneficial effects as follows: the present invention adopts the many circle of the zero defect sub-thread with insulation film lapping layer aluminum steels, is combined into multilayer transposition conductor strip through transposition, wherein every root circle aluminum steel mutually insulated.Covered composite yarn thin dielectric film outside transposed conductor band, glass fibre mixes ribbon layer and is coated on outside laminated film insulating barrier, improves this product proof voltage grade.And the glass fibre of outermost one deck mixes ribbon layer makes wire have better seal, and moisture and impurity are not easy to enter into inside wire, and then substantially increase reactor electric property, reduce the probability of turn-to-turn short circuit.Average more than the proof voltage 10000V of multilayer transposition aluminum conductor of the present invention, puncture voltage more than 26000V, be applicable to superhigh pressure and ultra high voltage field after tested.
