NBI缓冲器电源控制系统及可靠性设计

On the NBI Snubber Power Control System and Reliability Design

为了提高EAST系统运行参数,需要配备高功率辅助加热系统。中性束注入(NBI)是目前公认最为有效的加热方式,该系统供电电压高,功率大。采用缓冲器(Snubber)及其电源设备保护离子源加速极免受NBI系统运行中可能出现的击穿能量的影响。通过对缓冲器电源控制系统及可靠性的设计,满足NBI控制要求,为离子源加速极安全运行提供保障,并为下一步NBI束线优先决策控制器的连锁控制和故障保护奠定基础。

For improving system performance parameters, EAST needs high-power auxiliary heating system. NBI is generally believed to be the most effective heating mode,which can provide high voltage and power. To avoid breakdown energy causing serious damage to the accelerating electrode of the ion source when system is running, Applying Snubber and power supply protect it. By designing Snubber power communication and monitor system to provide security of the accelerating electrode of the ion source, which meets control needs of NBI, for the next it lay the foundation for beam line of priority decisions controller chain control and fault protection.
