摘要
小浪底反调节电站的主接线是单母线逐级扩大方式,两台机公用一条机压母线。因设计原因,机组机压设备室柜顶小母线存在不合理之处,7#、8#机组检修时会相互影响,降低了机组的年可用小时数。通过对比分析找出问题所在,并进行了7#、8#机柜顶小母线电气改造,提高了机组的可用小时数,取得了明显的经济效益、安全效益和社会效益。
The main wiring of The Xiaolangdi anti-regulation power plant is progressively expanding singlebus mode,press bus two generator public a High voltage bus.Unreasonable design makes 7 #, 8 # generator influence each other when the generator is Repaired.This reduces the number of hours the generator available.Through comparative analysis to identify the problems,we had 7 #, 8 # small bus on the top of the cabinet electrical transformation, and achieved remarkable economic,security benefits and Social benefits.
