摘要: 针对高功率脉冲电源集成系统连续放电的需求，研制了一种用于该系统的重频水冷电感。水冷电感在系统中既调节电源的电流波形，又能起到隔离作用。该重频水冷电感耐压高、通流大、充电间隔周期6 s，可连续工作10 次放电。针对连续放电的需求，通过去离子循环水对重频电感进行降温。现以单模块能量334 kJ、电感量30 µH、通流 100 kA为例进行设计分析，建立重频水冷电感温度场仿真模型，通过ANSYS仿真软件对该电感内部温度瞬态特性进行分析。结果表明：水冷电感通过去离子水冷却效果好，电感每次工作后温度最高达到47 ℃，在下一个工作点到来之前电感温度又恢复到41 ℃；同时该电感在没有加循环水的情况下通过了112 kA的电动力考核。试验结果与理论分析吻合较好，重频水冷电感运行稳定，从而验证了理论分析和设计的正确性。Abstract: To meet the requirement of continuous discharge in the integrated system of high power pulse power supply a repeatitive frequency water-cooled inductor for the system was developed. In the system, the water-cooled inductor can not only adjust the current waveform of the power supply, but also play an isolation role. The repeatitive frequency water-cooled inductor can withstand high voltage, large current, charge interval period of 6 seconds, and can work continuously for 10 times of discharge capacity. To meet the requirement of continuous discharge, deionized circulating water is used to cool the inductor. Taking the single module energy of 334 kJ, inductance of 30 μH, and current of 100 kA as an example, the design and analysis are carried out to establish the temperature field simulation model of the inductor, and analysis is made on the transient characteristics of the internal temperature of the inductor through ANSYS simulation software. The results show that the inductor is well cooled by deionized water, and the maximum temperature of the inductor reaches 47 ℃ after each operation, and the temperature of the inductor recovers to 41 ℃ before the next operation point. At the same time, the inductor passes the 112 kA electrodynamic test without circulating water. The experimental results agree well with the theoretical analysis, and the inductor runs stably, which verifies the correctness of theoretical analysis and design.
