Description
(54) УСТРОЙСТВО ЗАЩИТЫ МОСТОВОГО УПРАВЛЯЕМОГО ПРЕОБРАЗОВАТЕЛЯ ОТ ПЕРЕНАПРЯЖЕНИЙ(54) DEVICE PROTECTION OF THE BRIDGE CONTROLLED CONVERTER FROM OVERVOLTAGE
схему ИЛИ на управп кхций эпектрод вентип В 2. Это приводит к его преждевременному включению, т. е. обеспечению пути дн протекани тока нагрузки. Аналогично работает устройство и при обрыве гаобого другого вентип .the circuit OR on the control of the electrode ventip B 2. This leads to its premature switching on, i.e., to ensure the path of the load current flow. The device also works in the same way if one other valve breaks.
Таким образом, обрыв пюбого вентип приводит к. отпиранию слведуюшего вентип , что исключает разрыв тока в цепи нагрузки и возникновение реренапр жений на шинах преофазоватеп .Thus, the interruption of any ventip leads to unlocking of the next ventip, which eliminates the discontinuity of the current in the load circuit and the occurrence of re-stresses on the tires preoperatively.
При обрыве вентип токи в цеп х прео&разоьатеп и перенапр жени на его зажима не превышают значений, соответствующих нормальному режиму работы. Авари допустима Б течение длительного времени, что снимает требовани к быстродействию откпючакхцих устройств,In the event of a break, the ventilating currents in the circuits of the transient and overvoltage on its clamps do not exceed the values corresponding to the normal mode of operation. Alarms are permissible for a long time, which removes the speed requirements for opener devices,
