摘要
本文在简介了本安型电源电气特性的基础上,重点阐述了"ib"型本安现场总线电源、"ia"型本安现场总线电源输出特性,分析了IEC61158-2标准为什么要求所有在现场总线上运行的设备必须对地绝缘。
On the basis of introducing the electrical characteristics of intrinsically safe power supply,this paper mainly expounds the output characteristics of"ib"intrinsically safe field bus power supply and"ia"intrinsically safe field bus power supply,and analyses why the IEC61158-2 standard requires that all equipment running on the field bus must be insulated to the ground.
