冲击电阻分压器高压臂电阻绕法分析

摘要

As for the impulse resistive voltage divider,we need to consider the impact on residual inductance when measuring a short impulse.Three non-inductance winding methods of the HV arm resistor of impulse resistive voltage divider are introduced.The inductance of three non-inductance winding methods is compared under the same condition and the impacts on inductance of different skeleton shape and perimeter are analyzed.Results show that the inductance of the two-wires-one-layer non-inductance winding method is the smallest under the same skeleton.The inductance of the rectangular skeleton is smaller than that of the round skeleton under the same skeleton perimeter.For rectangular skeleton,when the aspect ratio is closer to 1,the inductance becomes bigger.For round skeleton,the inductance almost keeps the same value while the skeleton perimeter changes.%对于冲击电阻分压器,在测量短脉冲时需要考虑剩余电感的影响.对冲击电阻分压器高压臂电阻的三种无感绕法进行介绍,比较了相同条件下三种无感绕法的电感值,分析了不同骨架形状和骨架周长对于电感值的影响.结果表明:在骨架相同的情况下,双线单层绕法的电感最小；对于双线双层反向绕法,骨架周长相同时,矩形骨架的电感小于圆形骨架的电感,矩形骨架长宽比越接近1电感越大；对于圆形骨架,电感值随着骨架周长的变化基本不变.
