PUNCHING TYPE POWER IMPACT CELL FOR PLASMA BLASTING

摘要

A punching type power impact cell for plasma blasting is provided to manufacture an internal conductor simply by forming an internal conductor using a punching type perforated metal foil, to control the electric energy used for an electric discharge by controlling the number and size of perforations, and to cut down the cost for blasting by connecting an internal conductor electrically before discharging electricity. The punching type power impact cell for plasma blasting comprises: an internal conductor(130) provided with at least one group of perforations(162) formed along the outer circumference of a nonconductor and connected with a primary electric wire(101) transferring electric energy; an external conductor(131) connected with the internal conductor(130) and connected with a secondary electric wire(102); and an insulator insulating the internal conductor(130) and the external conductor(131) partially and forming a closed space together with the external conductor(131) to fill up with an electrolyte(180).
