一、相控调压整流电路平滑无级调节牵引电机端压,可以减少调压过程中的电流冲击,使牵引电机力矩变化平滑,在机车起动的,可以较好地利用轮轨粘着力,一般可使起动牵引力提高8～10％;在运行中可以获得机车工作范围内的任意牵引力和机车速度;而且无级调压具有快速性,有利于更好地利用机车的惯性动能,特别是在山区线路,坡道多变的情况下,由于无级调压的快速性可节省电能2～3％。此外,采用相控调压,可取消笨重的有
First, the phase-controlled voltage regulator rectifier circuit Smooth stepless regulation of traction motor end-pressure, can reduce the current surge in the process of voltage regulation, the traction motor torque changes smooth, the locomotive start, you can make better use of wheel-rail adhesion, the general The traction force can be increased by 8 to 10%; during operation, any traction and locomotive speed within the working range of the locomotive can be obtained; and the stepless speed regulation has the advantages of rapidity, which is beneficial to making better use of the locomotive’s inertial kinetic energy, especially in the mountains In the case of changing lines and ramps, the energy saving of 2 to 3% can be saved due to the rapidity of stepless voltage regulation. In addition, the use of phase-controlled voltage regulator, you can cancel bulky
