摘要
以560 kW 10 kV三相异步高压高效电机为例,建立了电机三维温度场计算模型,运用有限元方法计算了高压高效电机在额定工况下的温度场分布。对比分析了少胶绝缘工艺、高效冷却风路以及优化电磁方案对高压高效电机温度场分布的影响,为产品优化和工艺验证提供了大量有效的数据,对高压高效电机的研发有着重要意义。
Taking 560 kw 10 kV 3-phase asynchronous machines as the prototype, a calculated mould to the 3D temperature field of the motor was established. The finite el-ement method was applied to calculate the temperature field distribution under the rated working condition of the HV and HE motor. Influence on distribution of the temperature field HV and HE motor resulted in adopting the less-rubber insulated workmanship, high-efficiency cooling wind path and optimization of the electromagnetic program were analyzed and compared, to provide large quantity of valued data, which would be of great importance to develop the HV and HE motors.
