电厂全绝缘浇注励磁母线选型分析

Selection and analysis of all insulated pouring excitation bus in power plant

针对励磁系统共箱母线存在易结露、绝缘降低等问题,本文对谏壁发电厂两台330MW机组励磁系统改造时选择使用全绝缘浇注母线作为励磁母线,进行了深入分析,从其技术参数选型验证及仿真分析等方面论证其在励磁改造中的安全可靠性,为全绝缘浇注母线在发电厂励磁系统的应用提供借鉴。

In view of the problems of easy condensation and insulation reduction of the common box bus in the excitation system.This paper analyzed on the excitation bus of two 330MW generator excitation system during the rehabilitation of the excitation system of the Jian Bi power plant deeply.And demonstrated the safety and reliability of the excitation rehabilitation from the selection and verification of technical parameters and simulation analysis.It can be used for reference for the selection of all insulated pouring bus in power plant excitation system.
