Изобретение касаетс электроснабжени потребителей , чувствительных к колебани м напр жени в сети, наиример синхронных двигателей .The invention relates to the power supply of consumers sensitive to voltage fluctuations in the network, for example, synchronous motors.
Известно устройство дл электроснабжени потребителей, подсоединенных к источникам питани через сдвоенный реактор таким образом , что потребители подсоединены к средней точке, а к крайним точкам подключены источники питани .A device for power supply of consumers connected to power sources through a dual reactor is known in such a way that consumers are connected to the midpoint, and power sources are connected to the end points.
Однако при коротких замыкани х за средним выводом сопротивление реактора становитс незначительным, так как токи в ветв х направлены встречно. Токи короткого замыкани достигают величин, опасных дл оборудовани и самого сдвоенного реактора.However, with short-circuits behind the middle lead, the resistance of the reactor becomes insignificant, since the currents in the branches are directed oppositely. The short-circuit currents reach values that are hazardous to the equipment and to the dual reactor itself.
Целью изобретени вл етс уменьшение мощности короткого замыкани у потребител .The aim of the invention is to reduce the short-circuit power of the consumer.
Дл этого устройство снабжено дополнительным реактором, средн точка которого соединена со средней точкой основного реактора , а кажда пара обмоток реакторов включена встречно.For this, the device is equipped with an additional reactor, the midpoint of which is connected to the midpoint of the main reactor, and each pair of reactor windings is connected in opposite directions.
На чертеже изображено предлагаемое устройство электроснабжени , где 1 и 2 - ветви первого сдвоенного реактора, 3 и 4 - ветвиThe drawing shows the proposed power supply device, where 1 and 2 are branches of the first dual reactor, 3 and 4 are branches
второго сдвоенного реактора, 5 и б - источники питани , 7 и 8 - потребители.second dual reactor, 5 and b - power sources, 7 and 8 - consumers.
Устройство имеет четыре ветви, концы которых соединены в общую точку, а началаThe device has four branches, the ends of which are connected to a common point, and the beginning
выведены. Эти ветви попарно св заны общим электромагнитным потоком. К одной паре ветвей 1 и 2 присоединены через выключатели источники питани 5 и 6, а к другой - потребители 7 и 8. Сопротивление такого реактораwithdrawn. These branches are pairwise connected by a common electromagnetic flow. Power supplies 5 and 6 are connected to one pair of branches 1 and 2, and consumers 7 and 8 are connected to the other. Resistance of such a reactor
зависит от направлени протекающих токов. В нормальном режиме работы токи в ветв х направлены встречно, магнитные потоки каждой пары ветвей реактора скомпенсированы и реактивное сопротивление невелико. При коротком замыкании за любой из ветвей магнитное равновесие нарушаетс , и сопротивление реактора резко возрастает.depends on the direction of the flowing currents. In normal operation, the currents in the branches are directed oppositely, the magnetic fluxes of each pair of reactor branches are compensated and the reactance is small. In the event of a short circuit behind any of the branches, the magnetic equilibrium is disturbed, and the resistance of the reactor increases sharply.
