Discharge breakdown method, discharge breakdown apparatus and manufacturing method of the breakdown apparatus

摘要

Inserting a pair of electrodes having a metal wire (5) connected between its lower end with the hole (2), inserting a pair of electrodes with a metal wire (5) (5) and the fracture (4) are arranged in a bag-like container (22) made of rubber in the step of supplying the accumulated electric energy of the condenser at the electrode to melt-vaporize the volume of the fracture Destroying the fife monster (1) and inserting the bag-like container (22) into the hole (2). This method ensures safe transfer of inflating force to the pirate monster even when the formed hole of the pirate monster is deformed.
