The characteristics of a thyristor valve according to the invention appear from the invention. The following is described in connection with the accompanying figures which show a thyristor in a thyristor valve according to the invention. The thyristor EE is one of the series-connected thyristors included. in valve The thyristor is equipped with a control device SD connected to the control of the thyriometer for ignition of the thyristor.
