| 摘 要： | 为研究牵引逆变器输出脉冲电压对变频牵引电机绝缘的影响,基于高压脉冲电源,结合牵引逆变器的特点,研制了一种新型高压脉冲电源,脉冲电压峰峰值为0～10kV,频率为300Hz～20kHz,占空比为50%。试验结果表明,该高压脉冲电源上升沿2.95μs,输出功率1.5kW,完全满足变频牵引电机绝缘材料性能试验的要求。

| Abstract: | Inverter-fed traction motors used in express locomotive also experience a continuous pulse voltage with significant harmonics and transients. However, existing pulse power sources can't gratify test requirements. Consequently, a new type of high frequency and high voltage pulse power source is designed to investigate influences of continuous pulse voltage on insulation of traction motors used in express locomotive. Test results show that the pulsed power source can meet test requirements of traction motor insulation evidently. |
