Connection structure of fault detection devices for reactors and short circuit switch for these reactors to limit motor starting current and method of fault detection using the same

摘要

The present invention relates to a fault detection device for detecting faults of a motor starting current limiting reactor and a reactor short-circuit switch unit. Reactor short-circuit reactor and reactor short-circuit switch unit, characterized in that it comprises a structure of a reactor short circuit switch unit installed in series with the motor for each phase and a reactor for limiting the starting current connected in parallel to the upper end The present invention relates to a fault detection device for detecting a fault.;Motor, Current Limit, Reactor, Fault Detection, Reactor Protector
