Mobile Electric-Discharge Blasting Unit for Splitting off and Destruction of Rocks and Concrete

Abstract:

The article describes the pulse power system for electric-discharge blasting of rocks and concrete, the main equipment of which is a high current pulse generator with operating voltage up to 15 kV. The test of short-circuit experiment was produced, the main parameters of the discharge circuit L = 1.01 μH, R = 9 mΩ were calculated. Based on the results of the experiments the impedance Z = 42.5 mΩ of discharge circuit was defined. The pulse power system with mentioned parameters has maximum power condition deviation of about 8.6 %.
