摘要
针对取能电流互感器存在的启动电流大、铁心易饱和、无法适应较宽的输电线路电流等问题,对铁心部分进行设计与改进.依据初始磁导率、饱和磁通密度、铁心损耗以及成本等参数确定铁心材料,从铁心的选材上进行预处理;利用Ansys软件对铁心气隙形状进行设计并仿真,通过铁心在不同气隙形状下的磁泄露情况得出矩形半开口效果最优;采用控制变量法对气隙尺寸进行仿真,对铁心气隙尺寸进行了定量的分析,并对比分析了铁心的饱和特性以及二次侧输出功率情况,为电流互感器取能电源铁心的结构设计和参数的实际选取提供了良好的工程价值.
Abstract
In view of the existing problems of energy-taking current transformer,such as large starting current,easy saturation of core,and inability to adapt to wider transmission line current,this paper designed and improved the core part.The core material was determined according to the initial permeability,saturation flux density,core loss and cost,and the core material was pretreated.Ansys software was used to design and simulate the shape of the core air gap.Through the magnetic leakage of the core in different shape of the air gap,the rectangular half opening was the best effect.The control variable method was used to simulate the size of the air gap,quantitatively analyze the size of the core air gap,and compare and analyze the saturation characteristics of the core and the output power of the sec-ondary side.This provides a good engineering value for the structural design and actual parameter selection of the core of the current transformer energy source.
