摘要
介绍了中压变频原理,对中压电动机变频调速的技术特点和电路结构进行了分析。针对变频设备的特殊使用环境,提出变频设备对电动机运行的影响,计算结果与实验测试结果相符合。实用表明多电平结构具有较好的前景。
The paper describe the of medium voltageVF theory and nalyzes theVF timing technique of medium voltage motor and the circuit structure. Aiming at special working condition of frequency conversion equipments, We prqose that the inverter influences the motor. The calculating results are in concordance with the experimental ones. It is obvious that the multilevel structure will have foreseeable future.
