Safety requirements for electrical equipment for measurement , control , and laboratory use - part 2 - 032 : particular requirements for hand - held and hand - manipulated current sensors for electrical test and measurement 测量控制和试验室用电气设备的安全要求.第2 - 032部分:电气测量和试验用手持和用手控制电流感应器的特殊要求
Firstly , the thesis introduced a eoct scheme that supplied on a special coil . it utilized saturation of special coil to transform form 10a ~ 720a current of busbar to 8v ~ 40v voltage of inductions . after switched to direct current , it supplied the loads of sensor by dc - dc transformations , which is included two + 5v voltages with respective ground and a group of 12v voltage 该供能方案利用特制线圈的饱和特性，将母线电流大致在10a ~ 720a的电流感应约为8v ~ 40v的电压能量，利用整流桥将交流电变为直流电后，由dc - dc变换器件将其转换为两路不共地的+ 5v和一组12v电压供给后端传感头。
