针对不方便断电拆线的场合
设计了一种开合式微型电流互感器来代替常规电流互感器
从而实现在线安装. 通过选择方形铁芯
选用磁导率较大且切口平整、气隙较小的铁氧体为铁芯材料
设计了互感器的外壳结构. 经过实验分析表明
这种开合式微型电流互感器具有结构简单、使用方便、精度相对较高、线性度好的优点
并针对其正常工作时温升的情况及其漏磁对周围电子器件的影响做了数据分析. 最后指出了提高其精度的改进措施.
An open-close micro current transformer is designed for the situation where power disconnection is not applicable and it can replace the conventional current transformer
realizing online installation. The open-close micro current transformer has a square core and a casing made of ferrite with a high permeability
flat cut and small air gap. According to the experimental analysis
it has the advantages of simple structure
convenient operation
high precision and good linearity. In the end
the measures to improve its precision are proposed.
