Thyristor railway track switches forced commutating system for supply rectifier substation - contains common capacitor in parallel with clearing capacitors, of all path branches and reduces clearing capacitor voltage loading

摘要

The system for a rectifier network connecting a three-phase and/or a d.c. bus bar to a corresp. d.c. path contains a clearing circuit with a clearing thyristor and capacitor. A capacitor (C) common to all path branches has one pole coupled to the supply network and is connected via a bus bar (A) in parallel with the clearing capacitors (CL) of the path branch cells (SAZ1, SAZ2, SEZ). USE/ADVANTAGE - For supplying d.c. current paths from three-phase of c.d. networks. Forced thyristor clearing reduces voltage load on clearing capacitors compared to conventional ones.
