Description

The efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking
Technical field
The utility model 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.
Utility model content
The purpose of this utility model is to provide the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking, solves 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 utility model 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 utility model 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.
Accompanying drawing explanation
Fig. 1 is the application schematic diagram of the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking in direct current group network system that the utility model proposes.
Fig. 2 is the structural representation of the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking that the utility model proposes.
The implication marked in figure: 1-is unshakable in one's determination, 2-winding, 3-epoxy plate, 4-insulating barrier, 5-support.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1 be the application schematic diagram of the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking in direct current group network system that the utility model proposes, as shown in Figure 2 be the structural representation of the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking that the utility model proposes, the utility model proposes the efficient non-crystaline amorphous metal intermediate frequency transformer of a kind of direct current networking, comprise iron core 1, winding 2, epoxy plate 3, support 5, winding 2 is around on iron core 1, and unshakable in one's determination 1 is non-crystaline amorphous metal AFCC-1000 rewinding material single-phase double-column formula structure; Winding 2 comprise by two copper-clad skins connect turn to armature winding, by two secondary winding that turn to of bag strip conductors parallel connection, armature winding outlet method is series connection, secondary winding outlet method is in parallel, and the outermost of armature winding, secondary winding has all overlapped a layer insulating 4; The integral part that iron core 1 and winding 2 form is linked together by support 5 and epoxy plate 3, and the operating frequency of intermediate frequency transformer is 1kHz.Namely, under 1kHz operating frequency condition, test under no-load condition, full load conditions, under normal circumstances all can meet the intermediate frequency transformation requirement in direct current networking.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection range of the present utility model.
