    • A circuit arrangement for monitoring a thyristor comprising an auxiliary thyristor disposed between the anode terminal and gate terminal the thyristor, and a signal generator device which contains a light-emitting diode for sending light signals to an evaluating device. In order to obtain a particularly simple and therefore functionally reliable design of the circuit arrangement, due to the elimination of a separate energy supply circuit, and to achieve emission of light signals with a particularly high light output, the signal generator device has a first pair of input terminals coupled in series with the auxiliary thyristor and the light-emitting diode is arranged between the input terminals of the signal generator device.
    • 一种用于监测晶闸管的电路装置,包括设置在阳极端子和栅极端子之间的辅助晶闸管,晶闸管,以及包含用于将光信号发送到评估装置的发光二极管的信号发生器装置。 为了获得电路布置的特别简单且因此功能可靠的设计,由于消除了单独的能量供应电路,并且为了实现具有特别高的光输出的光信号的发射,信号发生器装置具有第一对 与辅助晶闸管串联耦合的输入端子,并且发光二极管布置在信号发生器装置的输入端之间。
