Abstract
The invention discloses an efficient amorphous alloy medium frequency transformer for direct-current networking. The efficient amorphous alloy medium frequency transformer comprises an iron core, windings, an epoxy board and a support. The windings are wound around the iron core. The iron core is of an amorphous alloy AFCC-1000 wound core single-phase dual-column structure. The windings include the primary winding and the secondary winding, wherein the primary winding is formed by winding and connecting two copper sheets in series, and the secondary winding is formed by winding and connecting two flat wires in parallel. The wiring mode of the primary winding is series connection. The wiring mode of the secondary winding is parallel connection. The outmost side of the primary winding and the outmost side of the secondary winding are each sleeved with an insulation layer. The whole part composed of the iron core and the windings is connected with the epoxy board through the support. The working frequency of the medium frequency transformer is 1 kHz. Compared with a transformer adopting silicon steel sheet iron cores with the same voltage grade and the same capacity, the efficient amorphous alloy medium frequency transformer has the advantages of reducing the size, reducing no-load losses, improving the power density and the like.
Description
Technical field
The present invention relates to a kind of transformer, is the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking specifically.
Background technology
Along with the high speed development with information technology that increases rapidly of city size, sensitive load important load in electrical network and nonlinear-load get more and more, AC distribution net will face that line loss is large, power supply corridor is nervous and voltage sag, voltage fluctuation, mains by harmonics, a series of power quality problems such as three-phase imbalance phenomenon aggravation.Power distribution network based on direct current has than the better performance of interchange in transmission capacity, controllability and raising power supply quality etc., effectively can improve the quality of power supply, reduce electric energy loss and operating cost, contradiction between coordination bulk power grid and distributed power source, give full play to value and the benefit of distributed power source.In direct current networking, the conversion that realize low-voltage direct-current system and high-voltage direct current must adopt the intermediate frequency transformer of KHz level.Under KHz frequency condition, non-crystaline amorphous metal is thinner relative to silicon steel sheet band, has the feature less than core loss.And intermediate frequency transformer is higher than the power density of Industrial Frequency Transformer, under identical capacity conditions, intermediate frequency amorphous alloy transformer volume significantly reduces, and weight is lighter, thus economizes on resources and integral device possesses miniaturized and light-weighted feature.Therefore, intermediate frequency amorphous alloy transformer is adopted to be following a kind of development trend as the transformer of direct current networking.
In design of transformer in the past, be all the Industrial Frequency Transformer of silicon steel plate core mostly, their no-load loss, volume and pollution are comparatively large, and power density is also lower simultaneously.In addition, prior art literature search is found, adopt the application of intermediate frequency distribution transformer in direct current networking of amorphous alloy material also to there is no record.
Summary of the invention
The object of this invention is to provide the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking, solve the technical problem that Industrial Frequency Transformer no-load loss of the prior art and volume and pollution are comparatively large, power density is lower.
The present invention adopts following technical scheme: the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking, it is characterized in that, comprise iron core, winding, epoxy plate, support, described winding is around on described iron core, and described iron core is non-crystaline amorphous metal AFCC-1000 rewinding material single-phase double-column formula structure; Described winding comprise by two copper-clad skins connect turn to armature winding, by two secondary winding that turn to of bag strip conductors parallel connection, described armature winding outlet method is series connection, described secondary winding outlet method is in parallel, and the outermost of described armature winding, described secondary winding has all overlapped a layer insulating; The integral part that described iron core and described winding form is linked together by described support and described epoxy plate, and the operating frequency of described intermediate frequency transformer is 1kHz.
The beneficial effect that the present invention reaches: with voltage ad eundem, the transformer with the employing silicon steel plate core of capacity is compared, the advantages such as volume of transformer of the present invention reduces, and no-load loss reduces, power density increase.
