当同轴励磁机发生故障时,为了保证系统安全,将采用切换至备用励磁机运行,切换俗称有“热切”和“冷切”。一般通常采用“热切”。采用“热切”方式时,如果两台励磁机外特性较好且采用的切换点正确,一般不影响发电机的正常运行,对系统的干扰较小。两台直流励磁机能进行“热... When the coaxial exciter failure, in order to ensure system security, will switch to the standby exciter operation, switching commonly known as “eagerly” and “cold cut.” Generally used “eager.” When using the “eager” mode, if the characteristics of the two exciters are good and the switching point is correct, the normal operation of the generator is generally not affected, and the interference to the system is small. Two DC excitation machine to carry out "hot ...
