摘要
针对本安现场总线,提出3种不同的电源备份方案;对电源的保护模式也进行讨论,分为一般限流保护方式和针对本安开关电源的前端保护和后端保护;并对本安现场总线电源的发展趋势进行预测。
For intrinsically safe fieldbus,it proposed three different power backup solutions and discussed the protection mode of the power,which included general current limitation protection,front-end protection and back-end protection for intrinsically safe switching power.At last,it forecasted the development trends of power in intrinsically safe fieldbus.
