Detailed description of the invention
1 the present invention is described in detail below in conjunction with the accompanying drawings:
The loop construction of a kind of separate unit list device body 18 pulse wave rectifier transformator, this transformer coil is by voltage regulation coil 2, high-tension coil 1, low-voltage coil；
Wherein low-voltage coil is made up of five coils: phase shifting angle be-20 ° of basic coils 7, phase shift coil I 6, phase shifting angle be 0 ° basic coil 5, phase shifting angle be+20 ° of basic coils 4 and phase shift coil II 3；

Voltage regulation coil is the fluctuation in order to adapt to voltage on line side, and high-tension coil is corner connection, can be that triple-frequency harmonics provides path.By to the phase shift coil of low pressure and the distribution of basic coil turn, displaceable valve 20 ° mutually can be made.When netting side power supply and being added on high-tension coil, just inducing voltage at low-voltage coil, by the phase shift of low pressure, it is-20 °, 0 °, the voltage on valve side of+20 ° that valve side produces phase shifting angle, thus forms 18 pulse waves.Owing to separate unit can produce 18 pulse waves, instead of the former structure realizing 18 pulse waves with three transformators, thus reach the purpose of material-saving.
Low pressure is made up of five coils, and they are axially aligned, and the adjacent arrangement of coil of same angle, this arrangement mode can reduce horizontal leakage field.Simultaneously by selecting suitable line rule to make the phase shift coil of low pressure identical to thickness with the width of basic coil, thus ensure that the impedance of different phase shifting angle is consistent.
