STARTING AND PROTECTING DEVICE

摘要

FIELD: electrical engineering, starting and protection of single-phase asynchronous motor, for instance, of domestic refrigerators. SUBSTANCE: reduction of radio noises and possibility of use of electric systems for automatization of control over electric motor are achieved by exclusion of thermal relay and insertion of two time relays and logic element INHIBITION and proper intercouplings which allow electromechanical components of device to be replaced by electron ones. EFFECT: diminished mass and size characteristics, reduced radio noises and possibility of use of promising electric systems.
