Description
Technical field
The utility model belongs to transformer technology, is specifically related to a kind of dry type phase-shifting rectifier transformer.
Background technology
Phase-shifting rectifier transformer commonly used should have larger range of regulation, suitable phase shift is arranged again, to realize the multiple parallel running of Rectification Power Factor, thereby improve the ripple coefficient of direct voltage, alleviate the high order harmonic component that produces because of rectifying effect to the pollution of electrical network, can adopt in this respect available for different connection modes to realize, be one of mode wherein and adopt the phase shifting transformer of extend-triangle wiring for high-power rectifier transformer, realize that mode of connection and principle are that the phase-shifting rectifier transformer primary side adopts the extend-triangle wiring.Primary side has the closed-loop path of third harmonic excitation current flowing like this, no matter which kind of connection secondary coil adopts, the direct voltage that its rectification produces can have path, thereby reduce high order harmonic component to the infringement of electrical network, the Rectification Power Factor of this mode of connection is in a ratio of minimum because of transformer capacity and other modes of connection that phase shift increases.But existing extend-triangle wiring transformer, phase shift winding and main winding are that concentric type is arranged, when voltage request ± 5% and ± during the pressure regulation of 2x2.5%, the pressure regulation simultaneously of phase shift winding and main winding, be that phase shift winding and main winding are all drawn tap, therefore the tap number of lead-in wire is the twice of common power transformer.The lead-in wire wiring is complicated, in disorder, take up room greatly, is unfavorable for terminal block.
The utility model content
The purpose of this utility model is to provide a kind of dry type phase-shifting rectifier transformer, can with less lead-in wire tap realize ± 5% and ± pressure regulation of 2x2.5%.
Structure of the present utility model is: dry type phase-shifting rectifier transformer has full bias seam stack iron core, high pressure is the sectional circular cartridge type by coil, low-voltage coil is paper tinsel formula or drum type brake, it is characterized in that: high-tension coil is for can phase shift+15 ° or the extend-triangle wiring of-15 °, and phase shift winding and main winding are respectively that one section edge short transverse unshakable in one's determination evenly distributes up and down.
Said high-tension coil is by can phase shift+15 ° or the extend-triangle wiring of-15 °, and its structure is known by those skilled in the art.Said full bias seam stack iron core is prior art.
Press the utility model structure, those skilled in the art just can make at phase shift winding and main winding and draw the tap consistent with common power transformer lead-in wire tap number by conventional calculating, can realize the pressure regulation simultaneously of phase shift winding and main winding.The utility model is from pin configuration is consistent with common power transformer in appearance.
High and low pressure coil of the present utility model can be formed by Nomex paper covered wire or the Copper Foil coiling of H level enamelled wire or du pont company, and coil-conductor insulation, layer insulation, the insulation of coil upper and lower end parts and the inside and outside insulating cylinder of high and low pressure coil all can adopt the Nomex paper of du pont company or other F level, H level, C class F insulating material F.
The utlity model has following advantage:
The phase shift winding of transformer and the tap of main winding are few, and pin configuration is simple, are easy to processing.The utility model transformer device structure is simple, good manufacturability, appearance looks elegant, low cost of manufacture, safe and practical.

Fig. 1 is the elementary diagram of embodiment phase shift+15 °.
Fig. 2 is the elementary diagram of embodiment phase shift-15 °.
Fig. 3 is that embodiment works as phase shift tapping 2 master when linking together with main winding tap 5 and looks schematic diagram.
Embodiment
Embodiment: see the embodiment of Fig. 1 and Fig. 2, be the dry type phase-shifting rectifier transformer of pressure regulation 10000 ± 2 * 2.5% V.High-tension coil adopts the extend-triangle wiring to realize phase shift+15 ° or-15 °.Phase shift winding and the main winding of high-tension coil all adopt the afterbody pressure regulation, and the shunting tap of phase shift winding is 1～3, and the shunting tap of main winding is 4～6.Phase shift tapping 1 is 10000-5%V when linking together with main winding tap 6; Phase shift tapping 1 is 10000-2.5%V when linking together with main winding tap 5; Phase shift tapping 2 is 10000V when linking together with main winding tap 5, and phase shift tapping 2 is 10000+2.5%V when linking together with main winding tap 4; Phase shift tapping 3 is 10000+5%V when linking together with main winding tap 4.In figure, A, B, C represent respectively the line end of the every phase coil of phase-shifting rectifier transformer; A1, B1, C1 represent respectively the line end of the every phase coil main winding of phase-shifting rectifier transformer; X, Y, Z represent respectively the end of the every phase coil of phase-shifting rectifier transformer.
Above embodiment is only in order to be further described the utility model, and scope of the present utility model is not subjected to the limitation of illustrated embodiment.
