Abstract

Bridge arm reactors are subjected to composite current of AC and DC in operation, having both AC current distribution characteristics based on inductance distribution and DC current distribution characteristics based on resistance distribution. Aiming to study the differences in temperature rise, current and loss calculations are performed according to electromagnetism and heat transfer theories. The static temperature distribution law of the reactor and its influencing factors are analyzed. The results show that the loss of metal accessories accounts for 1.02% and the collector ring is prone to local overheating. The maximum temperature rise of the encapsulation shows a nonlinear decrease with the increase of the flow rate and the decrease of the ambient temperature. The winding hottest spot temperature in AC condition is higher than that in DC condition. The temperature distribution is more uniform in DC condition. The research results can provide reference for the design of temperature rise of reactors under AC-DC compound high current in actual engineering.
