摘要
影响变频交流牵引电机可靠性的关键部位是其绝缘系统。本文以JD117型变频交流牵引电机为研究对象,详细计算了在PWM方波作用下含有金属屑、气隙、砂粒等各种绝缘缺陷时的电场分布。
The key position influencing the inverter-fed traction motor reliability is insulation system.Taking type JD117inverter-fed traction motor as the investigated subject,the electric field distribution is detailed calculated when the insulation system contains various defects,such as sweep ings,gas cavity,and grains of sand etc.
