Rotor radial ventilation structure of primary helium circulator driven motor
The primary helium circulator driven motor(PHCDM)is the only active equipment in the pri-mary circuit of high temperature gas cooled reactor(HTGR),and its safety directly affects the safe and stable operation of the reactor.Aiming at the new problems caused by the influence of high temperature and high pressure environment and helium heat transfer working medium on the ventilation structural de-sign of drive motor wind path structure and related parameters,a fluid-structure coupled heat transfer model of three-dimensional wind path structure with two-sided rotor core was established and the flow characteristics of the heat transfer working medium helium in the rotor radial ventilation structure under high temperature and high pressure environment were calculated and analyzed,then the fluid flow and temperature rise of rotor core and rotor bars under dynamic and static conditions were studied.At the same time,the corresponding rules of different types of heat transfer working media were compared and a simulation test device was built.The measured data and numerical calculation results are in good agree-ment,which verify the rationality and correctness of the calculation and analysis results,and the results provide some theoretical reference for optimization of rotor wind path structure and effective improvement of cooling performance of the primary helium circulator driven motor.
