上图:两台变压器220kv侧应增加隔离开关和断路器,变压器的10kv侧也应加断路器。两台发电机必须加装断路器,发电机必须加装母线侧隔离开关。10kv负载也要增加母线隔离开关。
下图:是一个典型的110kv双母线带旁路。DL6是旁路断路器,在DL6检修的情况下,可以从I母线通过母联DL3到II母线,经过PG1到旁路母线,再经过PG2向XL1供电。
原则步骤:110kv所有设备运行在I母线,所有II母线刀闸断开。
合上母联DL3两侧G5、G6刀闸,合上PG1刀闸,合上DL3断路器向II母及旁母充电。
断开DL3断路器,合上PG2刀闸,合上DL3合环。
拉开DL4断路器解环。拉开G7刀闸,拉开G13刀闸。
这张倒闸操作票的操作任务:XL1由110kvI母线供电改为由母联DL3代替DL4断路器,经II母线及旁路母线向XL1供电,DL4转为检修。
根据《公路工程概预算编制办法》的规定,间接费中的规费计算公式是()
