DEVICE FOR EXCITATION OF SEISMIC WAVES Russian patent published in 2005 - IPC

FIELD: seismic prospecting, applicable for excitation of seismic waves by on unexplosive seismic source with an electromechanical drive.

SUBSTANCE: in the claimed device the main and additional excitation windings are made in the form of excitation windings of direct and reverse motion of the radiator operating member. The device uses a commutating capacitor, which via the first commutating thyristor is connected to the excitation winding of the direct and reverse motion of the operating member, and via the second commutating thyristor - to the excitation winding of the direct and reverse motion of the operating member, the commutating capacitor is shunted by the series-connected third diode and the third inductance coil.

EFFECT: enhanced efficiency and repetition frequency of force actions, simplified control of the amplitude and duration of the excited seismic waves.
