ELECTROMAGNETIC RELAY FOR SWITCHING ACCUMULATOR BATTERIES FROM PARALLEL TO COUPLED PARALLEL CHARGING

摘要

FIELD: electrical engineering.;SUBSTANCE: invention relates to electrical engineering, namely to an electromagnetic relay for switching accumulator batteries operating on charging from an individual wind-driven power plant, followed by conversion of accumulated energy using an inverter into electric current of the required voltage and frequency. Proposed electromagnetic relay in composition with electric generator provides switching of accumulator batteries from parallel charging to coupled parallel by means of voltage supplied to control electrodes of voltage thyristors, wherein the switching contact is electrically connected through controlled resistance to control electrodes of thyristors, which connect groups of storage batteries to parallel or coupled parallel charging. Disconnection of control electrodes and interruption of electric current flow through thyristors performs an anchor of an electromagnetic relay controlled by an electronic switch, the operating mode of which is provided by preliminary adjustment of resistance of an electromagnetic relay winding.;EFFECT: higher reliability of electromagnetic relay operation is technical result of invention.;1 cl, 2 dwg
