Description
ним электрот говой сетью 2, быстродействующего выключател 3 и сглаживающего реактора 4. Реактор 4 шунтирован последовательно соединенными резистором 5 и насыщающимс дросселем 6. Система электроснабжени обеспечивает питание потребител 7. Дроссель 6 выполнен так, что при рабочих токах потребител 7 сердечник дроссел 6 ненасыщен и индуктивность дроссел 6 больше, чем индуктивность реактора 4. При этом обща индуктивность параллельно соединенных реактора 4 и дроссел 6 практически равна индуктивности реактора 4.With it, an electrical supply network 2, a fast-acting switch 3 and a smoothing reactor 4. The reactor 4 is bridged by series-connected resistor 5 and saturating choke 6. The power supply system provides power to the consumer 7. The choke 6 is designed so that with the operating currents of the consumer 7 the core of the throttle 6 is unsaturated and inductance Drossel 6 is greater than the inductance of the reactor 4. In this case, the total inductance of the parallel-connected reactor 4 and Drossel 6 is almost equal to the inductance of the reactor 4.
При коротком замыкании в электрот говой сети 2 (показано стрелкой на чертеже) ток в системе электроснабжени резко возрастает , что вызывает насыщение сердечника дроссел 6 и снижение его индуктивности до величины, во много раз меньшей индуктивности реактора 4. Вследствие того, что больша часть энергии, запасенна в реакторе, гаситс в шунтирующем его резисторе , сокращаетс врем отключени выключател и снижаетс энерги , выдел ема в дугогасительной камере выключател , увеличива срок его службы.When a short circuit in the electric network 2 (shown by an arrow in the drawing), the current in the power supply system increases dramatically, which causes saturation of the core of the throttle 6 and reduction of its inductance to a value many times smaller than the inductance of the reactor 4. Due to the fact that most of the energy stored in the reactor, extinguished in a shunt resistor, shortens the switch-off time and reduces the energy released in the arcing chamber of the switch, increasing its service life.
Одновременно значительно снижаетс коммутационные перенапр жени на щинах источника питани , что облегчает работу разр дников подстанции и электроподвижного состава. Кроме того, из-за уменьшени времени отключени короткого замыкани сокращаетс количество пережогов контактной сети.At the same time, the switching overvoltages on the power supply source women are significantly reduced, which facilitates the work of substation and electric rolling stock dischargers. In addition, due to the reduction of the tripping time of the short circuit, the number of contact network burns is reduced.
