DEVICE FOR DETECTING FAULTS IN ROTARY ELECTRIC CIRCUITS OF BRUSHLESS EXCITERS OF SYNCHRONOUS MACHINES

摘要

The proposed device includes an induction pickup for checking the circuits under control mounted close to these rotary circuits conducting an electric current. The output of the induction pickup of the controllable circuits is connected to one of the inputs of a signal distributing unit made in the form of a trigger counter whose outputs are connected to a diode matrix. Connected to the other input of the signal distributing unit is the output of an interrogation pulse shaping unit. The output of the signal distributing unit is connected to the inputs of a unit for controlling and indicating the condition of the circuits under control employed for light signalling about a fault and for sending signals to the system for automatic control and protection of the exciter and the synchronous machine excited thereby.
