摘要
FIELD: electricity.;SUBSTANCE: microcontroller device for diagnostics of turn-to-turn insulation of electric motor winding against self-induction voltage contains microcontroller 1, voltage divider 2, the first RC-filter 3, controlled electronic switch 4, indicator 5, the second RC-filter 6, controlled power source 7 and electric motor winding 8 subjected to diagnostics. At that output of the second microcontroller of pulse-length modulation is connected to the output of the second RC-filter 6 which output is connected to control input of the current source 7, which first terminal is connected to the second output of the switch 4 while its second terminal is connected to the second output of winding 8 subjected for diagnostics.;EFFECT: control of interrupting current in the circuit of electric motor winding subjected to diagnostics.
