APPLICATION STRUCTURE OF FOLLOW CURRENT BLOCKING DEVICE IN THREE-PHASE FOUR-CIRCUIT JOINT SPANNING STEEL TOWER

摘要

PROBLEM TO BE SOLVED: To provide an application structure of a follow current blocking device in a three-phase, four-circuit joint spanning steel tower that strikes a balance between the reduction of momentary drop occurrence probability and the reduction of equipment cost.;SOLUTION: This is the application structure of the follow current blocking device in the three-phase four-circuit joint spanning steel tower, which attaches the follow current blocking device to five phases from the superordinate phases of an upper transmission line and also attaches dynamic current breakers to five phases from the superordinate phases of a lower transmission line, in an equal voltage class joint spanning steel tower, and the application structure of the follow current blocking device in the three-phase four-circuit joint spanning steel tower, which attaches the follow current blocking device to five phases from the superordinate phases of the lower transmission line, in the different voltage class joint spanning steel tower.;COPYRIGHT: (C)2010,JPO&INPIT
