Patent ID: 7116543

Claim:
An electric power supplying apparatus for a rock explosion cartridge, comprising: a power source for generating an electric energy; a plurality of channels consisting of: capacitors for storing an electric energy from the power source; explosion cartridges for being exploded by the electric energies of the capacitors; input switches for switching the capacitors; and a controller for turning on/off the input switches of the plurality of the channels; and the plurality of the channels being connected to the controller in parallel, wherein the input switch comprises: a pair of main electrodes facing to each other; a pair of main electrode blocks connected to the main electrodes respectively, for supporting the main electrodes respectively; an igniting electrode connected to any one of the two main electrodes; an igniting electrode block connected to the igniting electrode; an insulated vessel for sealing the pair of the main electrodes and the igniting electrode in vacuum; a high voltage generator for supplying a high voltage through the igniting electrode block to the igniting electrode; and the main electrodes being connected through the main electrode blocks to the capacitor, and the controller turning on/off the high voltage generator so as to turn on/off the input switch.
