Summary:Arc-heated facilties play an important role in ground tests, such as appraisal of thermal protection systems(TPS) of various hypersonic vehicles and simulation of a high Mach scramjet's thermal structure and combustion chamber performance. This paper analyzes the requirements for developing a high power arc heater. Key technologies for developing it include high power, high voltage, high enthalpy and electrode erosion in high currents. Finally, the paper proposes the related ideas and methods for these key technologies, providing theoretical references for China's development of a super-high power arc heater. 电弧加热设备在各类高超声速飞行器热防护系统地面试验考核验证、高马赫数超燃发动机热结构及燃烧室性能模拟试验中发挥越来越重要的作用。分析了大功率电弧加热器发展需求以及大功率、高压、高焓、大电流电极烧蚀等关键技术，提出了相应的解决思路和探索方法，为我国超大功率电弧加热器的研制提供借鉴。
