Abstract

Устройство автоматического ограничения развития резонансных повышений напряжения на отключенных фазах ЛЭП, оснащенной шунтирующими реакторами, в режимах одностороннего примыкания такой линии к электрической системе, состоящее из пускового органа, содержащего, по меньшей мере, одно реле напряжения, избирательного органа, фиксирующего возникновение неполнофазного режима, органа выдержки времени, а также выходных реле, обеспечивающих действие на отключение выключателей смежных с неполнофазно включенным линейным выключателем.A device for automatically limiting the development of resonant voltage surges on disconnected phases of a power transmission line equipped with shunt reactors in the modes of one-sided adjacency of such a line to an electrical system, consisting of a starting element containing at least one voltage relay, an electoral organ detecting the occurrence of an out-of-phase mode, an organ time delays, as well as output relays, providing an effect on the tripping of circuit breakers adjacent to a line-circuit breaker that is not phase connected.
