Abstract

Способ контроля ложного отключения головного и секционирующего выключателей с последующим включением выключателя сетевого пункта автоматического включения резерва (АВР) в линии кольцевой сети, заключающийся в фиксации бросков токов короткого замыкания (КЗ) и в измерении времени между ними, отличающийся тем, что с момента исчезновения напряжения, рабочего тока и отсутствии тока КЗ в линии основного источника питания начинают отсчет времени выдержки включения выключателя сетевого пункта АВР, при этом в момент окончания этого времени в линии резервного источника питания контролируют увеличение рабочего тока и, если в момент окончания отсчета времени рабочий ток увеличился на значение, равное значению исчезнувшего рабочего тока в линии основного источника питания, то делают вывод о ложном отключении головного и секционирующего выключателей и включении выключателя сетевого пункта АВР.A method for controlling the false shutdown of the head and sectioning switches with the subsequent turning on of the circuit breaker of the automatic transfer switch (ATS) network point in the ring network line, which consists in fixing the surges of short circuit currents (SC) and in measuring the time between them, characterized in that from the moment the voltage disappears , operating current and the absence of short-circuit current in the line of the main power source begin the countdown of the shutter speed of the circuit breaker of the ABP network item, while at the end of this time in l The lines of the backup power source control the increase in the operating current and, if at the time the countdown ends, the operating current increases by a value equal to the value of the disappeared operating current in the line of the main power source, they conclude that the head and section switches are turned off and the circuit breaker of the ATS network point is turned on.
