Circuit Assembly for Overvoltage Limiting of An Excitation Coil of A Syncronous Machine Having Fast De-Excitation |
摘要 |
A circuit arrangement for de-exciting an excitation winding of a synchronous machine in the event of a fault, including a control circuit for controlling a current flow through the excitation winding, it being possible to apply a positive control voltage to the excitation winding for excitation and a negative control voltage for rapid de-excitation, and including a protective circuit which is parallel-connected to the excitation winding and which does not permit a current flow over the protective circuit in the event of rapid de-excitation and which forms a current path for limiting the voltage and de-exciting the excitation winding if at least one connecting line between the control circuit and the excitation winding is interrupted.
