Abstract

The relevance of the study is caused by the need to develop new sources of powerful current pulses for operation in an electrohydrau& lic device with moving electrodes that can be used to excite seismic waves in non&explosive seismic surveys. The aim of the research is to carry out computational and experimental studies of operation of a low&voltage shock generator on an arc in water, initiated by moving electrodes in the mode of single pulses and in production of a series of pressure pulses. Optimization of the parameters of the shock generator and the electrohydraulic radiator, in order to obtain the maximum pressure pulse. Objects: low&voltage shock generator, made in the dimensions of the crane asynchronous motor MTН&612, connected to an electrohyd& raulic source with moving electrodes. Methods: matching parameters of a shock generator and an arc discharge by the method of experiment planning using a mathemati& cal model. Results. The authors have carried out the laboratory studies of operation of a low&voltage shock generator on an arc in water initiated by moving electrodes in the regime of single pulses and in the generation of a series of pulses. Using the method of experiment plan& ning, the authors obtained the mathematical model of the shock generator operation on an arc in water, initiated by moving electrodes in the regime of single pulses; the regression equations are obtained for output parameters of the arc discharge. Optimization of the pa& rameters of the shock generator and the electrohydraulic source was carried out, which allows obtaining the maximum pressure pulse for seismic exploration at shallow depth. The obtained amplitude&frequency spectrum of the pressure pulse showed that the main ener& gy of the pressure pulse lies in the low&frequency range from 0 to 180 Hz, which provides a high seismic efficiency for seismic explora& tion at shallow depth.
