DEVICE INCREASING RELIABILITY single circuit overhead line 35 kV and above

摘要

1. An apparatus to improve reliability single-circuit line 35 kV and up without interruption of power supply and improving the reliability of electric lines, characterized in that the head of OSG and the receiving end further comprises establishing the fourth switch, and at each transmission tower is mounted with an additional fourth yoke suspended reserve phase wire. ! 2. Device according to claim 1, characterized in that to the input and output terminals of the fourth switch is connected adjacently, each phase separators with a spring drive, and the remaining two phases are connected with the busbar to the introductory terminals of this switch is also similar to the separator through isolating the first phase. ! 3. A device according to claim 1, characterized in that adjacent dividers fourth additional switch normally disabled and operate automatically on insertion and the adjacent isolating the first three switches normally turned on and off to operate automatically, the switches also have on their drive phase.
