Description
И (54) УСТРОЙСТВО ДЛЯ ЗАШ,ИТЫ КОНТАКТНОЙ СЕТИ ОБОРУДОВЛ1-ГИЯ ПОСТОЯННОГО ТОКА ОТ КОРОТКОГО ЗАМЫКАНИЯAND (54) DEVICE FOR WEB, IT OF A CONTACT NETWORK OF EQUIPMENT 1-GI DC BY A SHORT CIRCUIT
Устройство работает следующим образом . При повреждении или перекрытии одного из изол торов контактной сети на тросе группового заземлени по вл етс напр жение .The device works as follows. If one of the contact network insulators on the group ground wire is damaged or overlapped, a voltage appears.
Под действием этого напр жени по цепи: ограничивающее сопротивление 10 диод 9 - катушка 8 - поджигающий электро 5 - основной электрод 2, начинает протекать ток. В результате этого корь 6 электромагнитного привода 7 прит гиваетс и отводит поджигающий электрод 5 от основного электрода 2, присоединенного к заземленному элементу. Между электродами возникает мощна электрическа дуга, котора вызывает сильную ионизацию искрового промежутка между основными электродами и, как следствие, перекрытие всего промежутка. Это приводит к короткому замыканию контактной сети на заземленный элемент.Under the action of this voltage across the circuit: the limiting resistance 10 diode 9 - coil 8 - igniting electro 5 - main electrode 2, current begins to flow. As a result, the bark 6 of the electromagnetic actuator 7 is attracted and retracts the igniter electrode 5 from the main electrode 2 connected to the grounded element. A powerful electric arc arises between the electrodes, which causes a strong ionization of the spark gap between the main electrodes and, as a result, the overlap of the entire gap. This leads to a short circuit of the contact network to a grounded element.
Ток короткого замыкани , проход по дополнительным катушкам 14, создает сильное радиальное магнитное поле в промежутке между основными электродами.The short circuit current, the passage through the additional coils 14, creates a strong radial magnetic field in the gap between the main electrodes.
В таком поле дуга начинает врашатьс с большой скоростью между кольцевым электродами, что предотвращает их обгорание и повышаетс надежность устройства в работе.In such a field, the arc begins to rise at high speed between the ring electrodes, which prevents them from burning and increases the reliability of the device in operation.
Отключение короткого замыкани в контактной сети осуществл етс фидерной токовой зашитой т говой подстанции.The short circuit in the contact network is disconnected by the feeder current wired traction substation.
