Description

(54) СПОСОБ ПЕРЕКЛЮЧЕНИЯ ПОТРЕБИТЕЛЯ С ОДНОЙ СЕТИ ПЕРЕМЕННОГО ТОКА НА ДРУГУЮ(54) METHOD OF CONNECTING A USER WITH ONE AC VOLTAGE TO ANOTHER

Изобретение относитс  к способам управлени  низковольтными электрическими аппаратами, а именно, автоматическими переключател ми , выполн ющими функцию переключени  питани  с одной сети на другую . Переключатели предназначены дл  электроснабжени  ответственных потребителей , таких как вычислительные системы, системы регулировани , системы контрольно-измерительных приборов, системы автоматического управлени  сложными технологическими процессами, где некоторые элементы (например, запоминающие устройства ) не допускают длительного перерыва питани .The invention relates to methods for controlling low-voltage electrical apparatuses, namely automatic circuit breakers that perform the function of switching power from one network to another. The switches are designed to supply power to important consumers, such as computing systems, control systems, instrumentation systems, automatic control systems for complex technological processes, where some elements (for example, memory devices) do not allow a long power interruption.

Наиболее близким к изобретению по своей технической сущности  вл етс  способ переключени  потребител  с одной сети переменного тока на другую, заключающийс  в том, что переключение производитс  с помощью двух управл емых бесконтактных прерывателей переменного тока, содержащих встречно-параллельно включенные тиристоры в фазах обеих сетей, причем сигналы управлени  каждым тиристором формируют в интервале совпадени  напр жени  грти и тока потребител  в пол рности, соответствующей схемной пол рности тиристоров 1.The closest to the invention in its technical essence is the method of switching a consumer from one AC network to another, which means that switching is performed using two controlled AC contactless interrupters containing anti-parallel thyristors in the phases of both networks, control signals for each thyristor are formed in the interval of coincidence of the voltage and current of the consumer in the polarity corresponding to the circuit polarity of the thyristors 1.

К недостатку этого способа следует отнести неработоспособность при обрыве какой-либо фазы вышесто щего фидера работающей сети, так как в этом случае ток в фазе потребител  прекратитс  и, следовательно , не будут поданы сигналы управлени  на соответствующие тиристоры запасной сети.The disadvantage of this method is the inoperability when any phase of the upstream feeder of the working network is broken, since in this case the current in the consumer phase will stop and therefore no control signals will be sent to the corresponding thyristors of the backup network.

Целью насто щего изобретени   вл ет10 с  повыщение надежности работы при переключении с одной сети трехфазного тока на другую.The purpose of the present invention is to increase reliability of operation when switching from one three-phase current network to another.

Это достигаетс  тем, что в известном способе переключени  потребител  с одной сети переменного тока на другую с помощью встречно-параллельных тиристоров, установленных в фазах основной и резервной сетей, путем формировани  сигналов управлени  при переключении теми тиристорами, 20 схемна  пол рность которых соответствует пол рности напр жени  сети и тока потребител , при переключении дополнительно формируют сигналы управлени  тиристорами в фазах резервной сети, если токи вThis is achieved by the fact that in the known method of switching a consumer from one AC network to another using counter-parallel thyristors installed in the phases of the main and backup networks by generating control signals for switching by those thyristors, the circuit polarity of which corresponds to polarity network and current of the consumer, when switching, they additionally form thyristor control signals in the phases of the backup network, if the currents in
