Electronic switchgear e.g. compact starter for operation of engine, has break accelerator connected with micro controller for degradation of stored magnetic energy of electronically controlled magnetic drive

摘要

The switchgear (1) has a set of electronically controlled magnetic drives (10, 20) coupled with a micro controller (2), where the magnet drive (10) is protective drive and the magnetic drive (20) is a residual service life propel drive. An overload evaluation unit (3) is coupled with three current transformers (4) to evaluate and to process phase currents, where the current transformers are coupled with the microcontroller. A break accelerator (5) is connected with the micro controller for degradation of the stored magnetic energy of the magnetic drive (10).
