Abstract
Способ контроля аварийного отключения головного выключателя и ложного отключения секционирующего выключателя в линии кольцевой сети, заключающийся в фиксации бросков тока короткого замыкания (КЗ) и в измерении времени между ними, отличающийся тем, что при появлении броска тока КЗ в линии основного источника питания начинают отсчет времени, равный времени выдержки срабатывания защиты ГВ этой линии и, если в момент окончания этого отсчета ток КЗ исчезнет, то делают вывод об отключении ГВ линии основного источника питания, с момента отключения тока КЗ начинают отсчет времени, равный времени выдержки включения выключателя пункта АВР, и в момент окончания отсчета этого времени в линии резервного источника питания контролируют появление броска рабочего тока и, если он появляется значением меньше, чем значение отключенного рабочего тока линии основного источника питания и равный значению, определяемому нагрузкой подключенной к участку линии основного источника питания, расположенного в ней смежно с пунктом АВР, то делают вывод о ложном отключении секционирующего выключателя.A method of monitoring the emergency shutdown of the head switch and the false shutdown of the sectioning switch in the ring network line, which consists in fixing the inrush currents of short circuit (SC) and in measuring the time between them, characterized in that when the appearance of an inrush current in the main power line starts the countdown equal to the response time of the GW protection of this line and, if at the end of this countdown the short-circuit current disappears, then they conclude that the GV line of the main power source is turned off, from the moment of disconnection Short-circuit current starts the countdown equal to the shutter-off time of the switch of the ABP point, and at the end of the countdown of this time in the line of the backup power supply, the inrush of the operating current is controlled and, if it appears, is less than the value of the disconnected operating current of the main power supply line and equal to the value determined by the load of the main power supply line connected to the section of the line located in it adjacent to the ABP point, then they conclude that the sectionalizing switch is false disconnected la.
