Description
Technical field
It the utility model is related to a kind of single device body low pressure alternating expression and arrange 12 pulse wave rectifier transformers, belong to rectifier transformer
Technical field.
Background technology
Rectifier transformer is frequently with three-phase bridge or the rectification circuit of the double anti-star braid paralleing reactors of six phases.But both connect
Line mode pulse number in the case of not phase shift can only achieve 6, and rectifier transformer reduces exchange to improve power factor
The harmonic current of grid side, pulse number 6 are inadequate.Therefore, rectifier transformer will use certain phase shift system, Cai Nengshi
Existing multi-pulse rectification, reduces harmonic loss.
For 12 pulse wave rectifier transformers, traditional designing generally by phase shifting angle is -15 ° ,+15 ° of two rectifier transformers
Device is in parallel to form a Rectification Power Factor;Or be made up of two device bodies of separate unit, two device bodies are loaded in same fuel tank.Both
Design cost is high, loss is big, transformer efficiency is low.
The content of the invention
The purpose of this utility model is that providing a kind of single device body low pressure alternating expression arranges 12 pulse wave rectifier transformers, the change
Depressor is applied to the rectifier power system of aluminium electroloysis industry, chemical industry and other special trades.
The utility model to achieve these goals, adopts the following technical scheme that:
A kind of single device body low pressure alternating expression arranges 12 pulse wave rectifier transformers, and it includes first winding, tap-changing windings, high pressure
Winding, Phase shift winding and low pressure winding;
Tap-changing windings realize multistage continuous voltage regulating by loaded switch, and connect and supply with Phase shift winding to high pressure winding
Electricity;
High pressure winding is connected into indentation wiring with Phase shift winding;
Low pressure winding uses with contrary and even outlet method, and it includes and includes low pressure corner connection winding and low pressure star connects winding.
Further, low pressure corner connection winding and low pressure star connect the arrangement of winding alternating expression and are wound on same iron core, separate unit two
30 ° of phase shifting angle list device bodies can be formed between individual low pressure winding, realize 12 pulse wave rectifiers.
When pulse number is N*12, every rectifier transformer high pressure winding W3 and Phase shift winding W4 is connected into indentation wiring,
There is 360/N/12 (°) phase shift between each rectifier transformer successively, it is equivalent to form more pulse waves, realize N platforms rectifier transformer simultaneously
Through transport row.
The beneficial effects of the utility model:
1st, transformer device structure of the present utility model is simple, operates and easy to maintenance.
2nd, single device body pulse number of the present utility model is more, reduces influence of the harmonic wave to power network.
3rd, transformer loss of the present utility model is small, improves the efficiency of commutation system.
4th, holistic cost of the present utility model is low, and occupation of land is small, has energy-saving benefit and economic benefit.
