摘要

针对某些励磁大功率柜阻容保护存在的缺陷，文章分析其原因，分析晶闸管反向电压、整流变阻抗电压、晶闸管电流上升率对励磁整流装置阻容参数选择的影响，提出一种考虑相关参数进行励磁整流装置阻容参数计算的新方法，按照此方法设计的励磁整流装置阻容保护在现场运行情况很好。%To overcome the defects of some large excitation power cabinet resistance capacitance protection exists. Based on the analysis of the reason, analysis of thyristor tube reverse voltage and rectiifer transformer impedance voltage, the thyristor tube current rising rate of excitation rectiifer device resistance capacitance parameter selection effects, a new method is proposed to consider the related parameters of excitation rectiifer device resistance capacitance parameter calculation, in accordance with this method to design the excitation rectiifer device resistance capacitance protection in ifeld operation is very good.
