中压变频器对潜油电泵的影响及改进

Influence of medium -voltage inverter on ESB and improvement

介绍了现阶段各类中压变频器,着重分析了dv/dt的行波传输和高次谐波的产生原理以及对潜油泵性能的影响,同时针对潜油电泵给出了一些解决问题的方法.

The wide applicationofinverter willproduce harmonic anddv /dt,so this paper introduces some kinds of medium-voltage inverters ,and analyzes the principle of the traveling w ave of dv /dt and harmonic,at the same time presents some methods for solving pr oblems that effect on performance of ESP.
