DEVICE FOR CHARGING AND DESULPHATING ACCUMULATORS Russian patent published in 2020 - IPC H02J7/10 

FIELD: technological processes; electricity.

SUBSTANCE: invention relates to electrotechnical field of equipment, namely to charge accumulators with asymmetric current, and can be used in all fields of national economy. Device additionally includes parallel to multivibrator unit for protection against unauthorized disconnection of supply voltage, which includes relay, diode and indicator, wherein the multivibrator comprises a power switch unit with the possibility of switching direct and alternating voltage, as well as multivibrator there included are time-setting circuits consisting of resistors and capacitors with possibility of oscillation frequency and oscillation adjustment, and integrating circuits with possibility of vibrations frequency stabilization. Power switch unit includes a relay, a diode with the possibility to protect the device from self-induction EMF and a contact for connection of the charging and discharging circuits. Unit for protection against unauthorized disconnection of supply voltage is made on the basis of bipolar transistors and on thermal protectors, one of which is serially connected to the input circuit, and the other – to the output one. Indication of the unit for protection against unauthorized disconnection of supply voltage is a light-emitting diode connected in parallel to the winding of the electromagnetic relay. Charging circuit is connected through a charging resistor to the accumulator, at that it contains a switch with the possibility to adjust the charge current amplitude. Discharge circuit comprises an RC circuit for adjusting the amplitude and a resistor for discharging the capacitor.

EFFECT: technical result is higher reliability of device.
