摘　　要：针对大型湿式潜水感应电机损耗导致的温升问题,对大型湿式潜水电机运行过程中存在的铁心基本损耗、空载铁心附加损耗、负载铁心附加损耗、绕组基本损耗、绕组附加损耗、绕组端部损耗进行了分析。针对温度场有限元流固耦合仿真速度慢问题,基于传热学基本定律对大型湿式潜水感应电机进行分析,采用优化的等效热路图,基于等效热路法开发了适用于湿式潜水电机的温升计算程序。该计算程序能够高效、准确地对大型潜水感应电机的温升进行计算。最终,对一台160k W大型湿式潜水电机进行时谐场有限元建模与分析,求得了电机的铁心损耗、定子铜耗、转子铜耗与转差率的曲线图,并通过温升计算软件计算了该电机的温升,与样机试验进行对比,验证了优化后等效热路图的准确性。To address the problem of temperature rise due to losses in large wet submersible induction motors,the basic core losses,no-load core additional losses,and load core additional losses,winding basic losses,winding additional losses,and winding end losses that exist during the operation of large wet submersible motors are analysed.In view of the slow speed of the finite element fluid-solid coupling simulation of the temperature field,a temperature rise calculation program for large wet submersible induction motors is developed based on the basic law of heat transfer,using an optimised equivalent heat path diagram,and based on the equivalent heat path method.The calculation programme is able to calculate the temperature rise of large submersible induction motors efficiently and accurately.Finally,the time-harmonic field finite element modelling and analysis of a 160 kW large-scale wet submersible motor is carried out to obtain the graphs of each loss in the core,stator copper consumption,rotor copper consumption and the rate of rotation of the motor,and the temperature rise of the motor is calculated by the temperature rise calculation software,which is compared with the prototype experimental test to validate the accuracy of the optimized equivalent thermal circuit diagram.
