The Research And Design Of Impulse Current Generator Based On The Application Of The Industrial Lithotripsy

This thesis describes the application of pulsed power technology, makes it in aninstant release of the powerful current and the electrical energy into mechanical energyto break rocks.Firstly, the structure and working principle of it are mentioned. The principle ofbreaking rocks is analyzed in electical and mechanical aspects. When it discharges inthe liquid, electrohydraulic and cavitation effect, breakdown field strength betweenliquid and rocks, region most vulnerable to be crushed are produced, all these aspectscan break rocks. Comparing the current waveform design in traditional figure andMatlab graphical methods. The relection of components and waveform parameters areanalyzed in experiment. Introducing the various charge-discharge and loop parameters.Through the formula between pressure and current which is derivated by scientist fromSoviet Union, according to mechanical parameters of rocks, Matlab simulates theparameters of current waves which can break rocks. In the liguid, the gape energyconversion and total energy conversion of the whole device and the instantaneous wavepressure are calculated. According to the theoretical analysis, developing each module,designing simulation experiment device of current breaking rocks. It includes chargecontrol module, main discharge circuit module, measurement module, electode andcontainer module and so on. Then experiment with the simulation results, obseving theresults, analysing the component parameters and the physical and mechanical propertiesof rocks. According to theoretical analysis and experimental results, the experimentaldevice has been optimized and is able to achieve better results.
