Abstract

Изобретение относится к области электротехники, в частности к ограничителям мощности для применения в электрических сетях с напряжением до 0,4 кВ, предназначено для автоматического управления отключением цепей «Нагрузки» при превышении порогового значения уровня потребляемой мощности и непрерывного контроля параметров питающей сети. Технический результат: повышение скорости срабатывания защиты в трехфазных сетях переменного тока, возможность отключения «Нагрузки» от сети питания при повышении потребляемой мощности свыше установленного значения и автоматическое подключение «Нагрузки» после устранения причин перегрузки. Устройство контроля отличается тем, что вычислительный блок содержит микропроцессорное устройство А2, а измерительный блок снабжен средством А1 преобразования параметров входных сигналов напряжения и тока в цифровой код и выполнен с возможностью передачи цифрового кода на микропроцессорное устройство А2 вычислительного блока.The invention relates to the field of electrical engineering, in particular to power limiters for use in electrical networks with a voltage of up to 0.4 kV, intended for automatic control of disconnecting the “Load” circuits when the threshold value of the power consumption is exceeded and continuous monitoring of the parameters of the supply network. Technical result: increase the speed of protection operation in three-phase AC networks, the ability to disconnect the "Load" from the mains when the power consumption exceeds the set value and automatic connection of the "Load" after eliminating the causes of overload. The control device differs in that the computing unit contains the microprocessor device A2, and the measuring unit is equipped with the means A1 for converting the parameters of the input signals of voltage and current into the digital code and is configured to transmit the digital code to the microprocessor device A2 of the computing unit.
