励磁调节器整流桥结构配置可靠性分析

Reliability analysis of AVR Structure Configuration for Large Capacity Generator with Brushless Excitation

针对不同冗余配置的励磁调节器,提出可能存在单臂短路时故障扩大的风险,通过短路电流计算、可控硅导通特性和快速熔断器特性分析,得出不同配置的励磁调节器发生该故障的几率。

This paper introduces kinds of regulator with different redundant configura fully fault down if there is short circuit in one of the rectifier bridges. After calculating as analyzing the characteristic of bridge and fast fuse, the fault possibility of AVRs with ted in this paper. tion, and presents the risk of AVR the Short - circuit current as well different configuration are presen-
