Description
единенного анодом к «плюсу основной цепи .single anode to the "plus main circuit.
Выключатель работает следующим образом .The switch works as follows.
Выключение выключател осуществл етс индукционно-динамическим приводом при замыкании цепи катушки 9 на разр д отдельно накопительной емкости.The switch-off of the switch is carried out by an induction-dynamic drive when the circuit of the coil 9 is closed to discharge the storage tank separately.
При размыкании силовой цепи подаетс команда на включение элемента в шунтирующей цепи, например тиристора, и встречно зар женна емкость разр жаетс по контуру: 1, 8, 7, 6, 5, 3, через замкнутые контакты 1, 3 при этом срабатывает индукционно-динамический привод 6 и разводит контакты 1-3, причем дуга между контактами 3, 1 практически не возникает, а между контактами 2, 3 возникает либо искровой разр д, либо дуговой, длительность существовани которого определ етс временем перезар да конденсатора 7, причем применение контактов 2 с устройством провала может практически свести к минимуму вление дуги между контактами 2 и 3.When the power circuit is opened, the command is given to turn on an element in the shunt circuit, for example, a thyristor, and the countercharged capacitance discharges along the circuit: 1, 8, 7, 6, 5, 3, through the closed contacts 1, 3, the inductive-dynamic the actuator 6 connects contacts 1-3, and there is practically no arc between contacts 3, 1, and between contacts 2, 3 there is either a spark or an arc, the duration of which is determined by the recharge time of the capacitor 7, and the use of contacts 2 with the device prov la may substantially minimize the occurrence of arcs between the contacts 2 and 3.
Така конструкци выключател посто нного тока повышает его надежность путем значительного снижени электрической эрозии контактов за счет минимального времени горени дуги от тока перезар да шунтирующего конденсатора.Such a DC breaker design increases its reliability by significantly reducing electrical erosion of the contacts due to the minimum arc time from the recharge current of the shunt capacitor.
