摘要 一般来说,托卡马克(EAST)装置中的NBI加热系统都是利用Snubber来实现保护的。为了优化Snubber的结构,通常都给其添加一个偏置直流源,将Snubber的性能维持在BH曲线的负饱和点附近,这样能使Snubber的质量减小一半。而目前普遍使用的偏置直流源是将50/60 Hz的交流电经过高压隔离变压器变压后整流直接得到。50/60 Hz的高压隔离变压器体积大、质量重,将带来移动不便和占用大量空间等缺点,如将50/60 Hz变为高频后经高频高压隔离变压器处理,这一问题就能得到解决。基于高频高压技术进行了EAST Snubber高压隔离偏置电源的设计与实验研究。 Generally speaking,the NBI heating systems of Tokomak(EAST) are protected by Snubber.To optimize the structure of the Snubber,the bias current supplier is supplied to keep the performance of the Snubber around the negative saturation point of its BH major loop,which can reduce half weight of Snubber.The present NBI generally use 50/60 Hz high voltage(HV) insulation transformers to configure its DC power supplier to offer the bias current to the Snubber.But this 50/60 Hz HV insulation transformer is much heavier than high frequency(HF) high voltage(HV) insulation system,which result in many problems as occupying much spaces and difficulty to move.Those problems can be solved by transforming the 50/60 Hz into high frequency(HF).The experimental advanced superconducting tokamak(EAST) NBI Snubberwas designed and tested based on HF and HV technology.
