摘要
推导了非线性电阻灭磁过程中的发电机转子电流变化式。在此基础上,求出灭磁时间的计算公式。以定量分析的方法,来计算用氧化锌非线性电阻网络灭磁时间。
Abstract This article describes the change pattern of generator rotor current during de-excitation process with non-linear resistance. On this basis, the calculation formula for de-excitation time is derived . In this formula , quan -titatively analyzing method is used to calculate the de-excitation time with zinc oxide non-linear resistance network.
