Abstract

The article deals with a transmission line reservation device based on a design and technical solution providing replacement of traditional double-circuit transmission with a backup phase single circuit. The design and technical solution splits the backup phase into three components to be connected in parallel to operation phases of the overhead transmission line under normal operation conditions providing the symmetry of resistances and voltages. The greatest number of overhead transmission line failures are due to one-phase damages of the operation circuit. In this case, components of the split backup phase are united with switches and automatically connected to the operation circuit instead of the damaged one. It increases operational reliability of the wiring diagram, maintainability and capacity of the transmission line.
