Abstract
The invention discloses a dry-type iron-core reactor with a resin molded coil, which comprises a coil and an iron core, wherein the iron core is formed by fixing a plurality of core laminations together through an iron core clamping piece; the coil is sheathed on the iron core; the coil comprises a magnet wire with insulation on the outer side and a metallic foil cylinder with an opening on the inner side; the two ends of the opening of the metallic foil cylinder are overlapped, and the overlap section is staggered; the metallic foil cylinder and the iron core are connected with each other; insulating resin is molded between the metallic foil cylinder and the magnet wire with insulation; and both the metallic foil cylinder and the magnet wire with insulation are wrapped in the molded insulating resin. The invention completely converts the electrical insulation among the magnet wire, the iron core and the clamping piece in the coil into single resin insulation so as to reduce the distance between the coil and the iron core, thereby reducing the diameter of the coil, the usage of the magnet wire, the cost and the energy consumption.
Description
Technical field
The present invention relates to a kind of suitable resin-cast metal forming shielded coil dry-type iron-core reactor.
Background technology
Along with the development of human civilization, people are more and more higher for the requirement of power supply quality, and even to this day, reactor in application on power system more and more widely.Reactor can be divided into by its purposes: current limiting reactor, filter reactor, smoothing reactor, power factor compensation reactor, series reactor, interphase reactor, earthing reactor, arc suppression coil, inlet wire reactor, outlet reactor, saturable reactor, autotransducer, variable reactor (Regulatable reactor, controlled reactor), yoke stream reactor, series resonance reactor, parallel resonance reactor, starting reactor etc.Can be divided into by its structure: air core reactor, iron-core reactor (comprise two kinds of dry type and oil immersed types, its core limb all is made up of brace between one or more cakes unshakable in one's determination, insulation cushion and cake or connection lead, makes each metal part of core limb all be in same current potential with iron yoke and core clamping) and half heart reactor.
At present, the dry-type iron-core reactor of selling on the market can be divided into resin-cast, common sealing and three kinds of the dry types of ventilating, electric insulation intensity is the compound inslation by resin and air gap between its coil and iron core or folder, perhaps only lean on the single insulating of air gap to support, because the insulation property of air can not show a candle to the good insulation preformance of resin, under the situation of equal insulation distance, it is the insulation electrical intensity height that the compound inslation of single air-gap insulation or resin and air gap all can not show a candle to single resin, thereby, more than the insulation distance of three kinds of iron-core reactors all bigger, it is big to exist volume, consumptive material is many, the big problem that consumes energy causes cost higher.
Summary of the invention
Problems such as the volume that the present invention is directed to existing dry-type iron-core reactor existence is big, consumptive material is many, power consumption is big provide the resin-cast coil dry iron-core reactor that a kind of volume is little, power consumption is few.
Resin-cast coil dry iron-core reactor of the present invention adopts following technical solution:
This resin-cast coil dry iron-core reactor, comprise coil and iron core, unshakable in one's determination being fixed together by core clamping by each lamination forms, mounting coil is on iron core, the metal forming tube of the band opening of the electromagnetic wire of the tape insulation outside coil comprises and inboard, the opening two ends of this metal forming tube have overlapping, lap staggers, the metal forming tube is connected with iron core, be cast with insulating resin between the electromagnetic wire of metal forming tube and tape insulation, the electromagnetic wire of metal forming tube and tape insulation all is wrapped in the insulating resin of cast.
Metal forming tube and unshakable in one's determination being connected are to be connected plain conductor between metal forming tube inboard and core clamping, unshakable in one's determinationly are connected by the iron core grounding sheet with core clamping.
The present invention has changed the insulation form of the compound electric insulation of the single air-gap insulation between coil, iron core and the ground in the existing dry-type iron-core reactor or resin and air gap, electric insulation between electromagnetic wire in the coil and iron core and folder is converted into single insulation resin fully, dwindled the distance between coil and iron core greatly, thereby dwindled the diameter of coil, reduced the consumption of electromagnetic wire, dwindle volume, saved cost, and reduced energy consumption.
Description of drawings
Fig. 1 is the structural representation of resin-cast coil dry iron-core reactor of the present invention.
Fig. 2 is along the cutaway view of A-A line among Fig. 1.
Wherein: 1, iron core, 2, core clamping, 3, plain conductor, 4, insulating resin, 5, coil, 6, the electromagnetic wire of tape insulation, 7, the metal forming tube, 8, cross-over block, 9, the iron core grounding sheet.
Embodiment
As shown in Figure 1, the same with existing dry-type iron-core reactor, resin-cast coil dry iron-core reactor of the present invention also comprises iron core 1 and the coil of being made up of silicon steel sheet 5, each silicon steel sheet of unshakable in one's determination 1 tightens together by two groups of core clampings 2 up and down, unshakable in one's determination 1 is connected by iron core grounding sheet 9 with core clamping 2, coil 5 is sleeved on unshakable in one's determination 1 the outside, the two ends up and down of coil 5 and be provided with cross-over block 8 between two core clampings 2 up and down, and coil 5 is entwined by the electromagnetic wire 6 of tape insulation.
The present invention unlike the prior art be the metal forming tube 7 that is provided with an opening in the inboard of coil 5, metal forming tube 7 generally with Copper Foil or aluminium foil, also can be other conducting metals.As shown in Figure 2, the opening two ends of this metal forming tube 7 have a bit of overlapping, but do not overlap, and stagger.The inboard of metal forming tube 7 is welded with plain conductor 3, and the other end of plain conductor 3 links to each other with core clamping 2, is connected by the iron core grounding sheet with core clamping 2 owing to unshakable in one's determination 1, and therefore, metal forming tube 7, iron core 1 and core clamping 2 threes' current potential is identical.Filled by the insulating resin 4 of vacuum pouring between the electromagnetic wire 6 of metal forming tube 7 and tape insulation, metal forming tube 7 is all wrapped up by the insulating resin 4 of vacuum pouring fully with the electromagnetic wire 6 of tape insulation.Metal forming tube 7 forms with core clamping 2 by plain conductor 3 and is electrically connected reliably, so just the electromagnetic wire in the conventional coil and the electric insulation between iron core are converted into the electric insulation between electromagnetic wire and the metal forming, just the compound inslation with traditional electromagnetic wire and resin between iron core and air becomes pure insulation resin, improved the dielectric strength between coil electromagnetism lead and iron core and ground greatly, dwindle volume, realized material-saving, energy-conservation effect.Resin-cast coil dry iron-core reactor of the present invention uses best results in the electrical network of 3～110kV.
