Description
трактов 1 и 2 соответственно, промежуточные секционированные резисторы 7, 8 вспомогательных трактов 3 и 4 соответственно, высокоомные резисторы Я 0, отводы 11, 12 трансформатора и нагрузочные ветви 13, 14.paths 1 and 2, respectively, intermediate partitioned resistors 7, 8 auxiliary paths 3 and 4, respectively, high resistance resistors I 0, taps 11, 12 of the transformer and load branches 13, 14.
Устройство работает следующим образом.The device works as follows.
Пусть требуетс переключить нагрузку с отвода // на отвод 12. Сначала замыкаютс оба, механически соединенные друг с другом, контакты 3-/ и 3-2 вспомогательного тракта 3 нагрузочной ветви 13, а затем сразу же размыкаютс оба контакта /-/ и /-2 основного коммутирующего тракта 1 той же нагрузочной ветви (фиг. 2). При этом коммутируемое напр жение распредел етс соответствующим образом на оба контакта основного тракта 1 при помощи резистора 5 в зависимости от соотношени величины сопротивлени секций промежуточного резистора 7. При следующем шаге замыкаютс оба, также соединенные друг с другом, контакты вспомогательного тракта 4. В этом положении дополнительно к току нагрузки между отводами // и 12 протекает ток, ограниченный резисторами 7 S и высокоомными резисторами 9, 10 (фиг. 3).Let it be required to transfer the load from the drop // to the tap 12. First, both contacts are mechanically connected to each other, contacts 3- / and 3-2 of the auxiliary path 3 of the load branch 13, and then immediately both contacts / - / and / - are opened 2 of the main switching path 1 of the same load branch (Fig. 2). In this case, the switched voltage is appropriately distributed to both contacts of the main path 1 by means of a resistor 5, depending on the ratio of the resistance values of the sections of the intermediate resistor 7. At the next step both contacts of the auxiliary path 4 are closed. In this position in addition to the load current between the taps // and 12, a current flows limited by resistors 7 S and high-resistance resistors 9, 10 (Fig. 3).
Следующий шаг вызывает размыкание обоих контактов 3-1 и 3-2 вспомогательного тракта 3. Благодар подключению в этом положении высокоомного резистора 9 достигаетс равномерное распределение коммутируемого напр жени на контактах вспомогательного тракта 3 (фиг. 4). На последнем щаге коммутации замыкаютс оба контакта 2-/ и 2-2 основного тракта 2 нагрузочнойThe next step causes the opening of both pins 3-1 and 3-2 of the auxiliary path 3. By connecting the high-resistance resistor 9 in this position, a uniform distribution of the switching voltage on the contacts of the auxiliary path 3 (Fig. 4) is achieved. On the last switching pole, both contacts 2- / and 2-2 of the main path 2 of the load are closed.
ветви 14, а оба контакта 4-/ и 4-2 вспомогательного тракта 4 данной нагрузочной ветви размыкаютс , и весь ток нагрузки проходит через контакты основного тракта 2 нагрузочной ветви 14 (фиг. 5).branches 14, and both pins 4- / and 4-2 of the auxiliary path 4 of this load branch are opened, and the entire load current passes through the contacts of the main path 2 of the load branch 14 (Fig. 5).
Процесс переключени нагрузки на последующие отводы аналогичен выщеописанному .The process of transferring the load to subsequent taps is similar to the one described above.
