大截面分割导体直流电阻测试误差分析与改进

Error Analysis and Improvement of Large Sectional Conductor DC Resistance Measurement

主要对采用常规的侧面电流输入法测试大截面分割导体直流电阻易产生测试误差的原因进行了分析,进而发现了一种导体直流电阻端面电流输入测试新技术。对新旧两种测试方法进行了对比,结果显示端面电流输入法对大截面分割导体直流电阻的测试数据更稳定,结果更真实。

By analyzing the reson vhy it is easy to occur deviation when testing the DC resitance of split large crosssection conductor by regular side-face current input method,we innovatively find a new DC resitance testing technology of conductor called end-face current input.Compared and contrast these two methods by data analysis,the result shows that the testing data of split large cross-section conductor is more steady and the testing result is more accurate by end-face current input method.
