Abstract
A static convertor arrangement includes at least two static convertors, the direct current sides of which are series connected and connected to a direct current line, while the alternating current sides are connected to an alternating current network. Each convertor is provided with a control system controlled from a regulator and each convertor is parallel-connected on the direct current side to a short-circuit member. For reconnection of a short-circuited convertor, a starting regulator is provided which is fed by a desired value emitter representing the current present in the arrangement and an actual value emitter which represents the current in the convertor in question. The control system of at least one of the convertors has a contact for switching between the first regulator and the starting regulator. The short-circuit member for one of the convertors is provided with an operating device for opening the member, which is controlled by the current in the short-circuit member.
