It includes from lotus root and stabilizes winding, become basic winding from lotus root and become tap-changing windings from lotus root；Rectification side transformer is by two independent magnetic circuits
Rectifier transformer composition, every rectifier transformer realizes 12 pulse waves, every rectifier transformer include Phase shift winding, substantially about
Group and low pressure winding；The continous way is powered by on-load voltage regulating switch to two rectifier transformers from lotus root adjustable transformer.
Further, 24 pulse wave rectifier transformer of a kind of continuous voltage regulating above-mentioned, in which: pressure regulation side transformer with it is whole
Flow side transformer in box shell in time interval arrange, two rectifier transformers of rectification side transformer in box shell between left and right every
Arrangement.
Further, 24 pulse wave rectifier transformer of a kind of continuous voltage regulating above-mentioned, in which: rectification side transformer is by two
Platform conjugated rectifier transformer composition, every conjugated rectifier transformer realize 12 pulse waves.
Further, 24 pulse wave rectifier transformer of a kind of continuous voltage regulating above-mentioned, in which: rectification side transformer is by two
The double splitting type commutator transformer compositions of platform, every double splitting type commutator transformers realize 12 pulse waves.
Further, 24 pulse wave rectifier transformer of a kind of continuous voltage regulating above-mentioned, in which: rectification side transformer is by two
Platform rectifier transformer composition, low pressure winding axial direction y, d of every rectifier transformer connect cross arrangement and realize 12 pulse waves.
Through the implementation of the above technical solution, the beneficial effects of the present invention are: with it is existing by more transformers connected in parallel and
At 24 pulse wave rectifier transformers compare, 24 pulse wave rectifier transformer separate unit of this continuous voltage regulating is achieved that form two
The purpose of 14 pulse waves, small on ground with accounting for, manufacturing cost and use cost is low, and one-time investment is small, and product competitiveness height etc. is excellent
Point；In the case where same occupied area, more pulse numbers are able to achieve, keep electrolytic rectifier transformer station high-voltage side bus waveform closer
Sine wave keeps equipment operation more stable, safe and reliable.
