| 摘要 |
The invention concerns a firing device for a number of electric valves, particularly thyristors. Each thyristor control path is associated with a firing circuit with a detector for electromagnetic radiation responsive to a transmitter which is controlled by a firing control signal and is equipped with a radiating device which energizes the individual detectors. To transmit the firing control signal with sufficient strength, a transmitter with a radiator is provided which is arranged in the focal line of a reflector designed as a partial elliptical cylinder. The individual detectors are disposed in a line which is aligned essentially parallel to the focal line of the reflector. |
