ELECTRONIC AUTOMATIC CIRCUIT BREAKER WITH ALTERNATIVE OPERATION MODE USING AUXILIARY POWER SUPPLY SOURCE

摘要

FIELD: electricity.SUBSTANCE: application: in electrical engineering. The electronic automatic circuit breaker includes controlled mechanical contacts designed to be connected to the main power supply source with at least one load and control circuit intended to control passage of electric energy from the main power supply source to the load, to detect failure states and automatic contact opening in response to the detected failure state. The main power supply source supplies the control circuit when the contacts are closed while the auxiliary power supply source supplies the control circuit when the contacts are open either due to automatic or manual opening.EFFECT: auxiliary resource is provided for the electronic module supply in order to specify the failure type without repeated actuation of the failure.12 cl, 2 dwg
