SYSTEM OF SUPPLY AND CONTROL OF ELECTROMAGNETIC DOUBLE-ACTION HAMMER WHICH IS PART OF VIBRATION SOURCE Russian patent published in 2024 - IPC E21B28/00 

FIELD: physics.

SUBSTANCE: invention relates to vibroseis equipment. Power supply and control system of the double-action electromagnetic hammer, which is part of the vibration source, includes a controlled rectifier (CR) connected to a three-phase AC network, thyristor switch is connected to the output of the CR, which includes a damping unit consisting of a resistor, a capacitor and diodes, a switching capacitor and a control unit. Control unit is a current analysis unit (AU), made in the form of two switching elements control channels, each of which includes series-connected correcting device (CD), microcontroller (MC), comparator (C), inverter (I) and amplifier (A). Outputs of each of the channels are connected to the control electrodes of the thyristors VT₁ and VT₂ of the switch, in the arms of which the current sensors CS₁ and CS₂ are connected in series with the L_ds coils of the direct and L_rs reverse stroke of the electromagnetic hammer, generating signals proportional to the value of current in the coils L_ds, L_rs; signals from current sensors CS₁ and CS₂ are supplied to the AU input.

EFFECT: disclosed is a system for feeding and controlling a double-action electromagnetic hammer, which is part of a vibration source.
