摘要：
To provide a discharge device capable of generating impulse waves by phreatic explosion due to underwater discharge which is the same as conventional one and is caused between electrodes, with a voltage lower than a conventional high voltage.SOLUTION: A discharge device includes: a pressure container filled with conductive liquid； a first discharge electrode and a second discharge electrode arranged in the conductive liquid in the pressure container while being spaced by a prescribed distance； and a power supply part having an outside switch applying a prescribed voltage on the first discharge electrode and the second discharge electrode. The first discharge electrode and the second discharge electrode are connected by an extra fine conductor, and a prescribed voltage is applied on the first discharge electrode and the second discharge electrode by an outside switch of the power supply part, so that the impulse waves are generated by the phreatic explosion of the conductive liquid due to in-liquid discharge through which the prescribed voltage is passed to the extra fine conductor.SELECTED DRAWING: Figure 1【課題】従来の高電圧よりも低電圧により従来と同様な電極間で発生する水中放電による水蒸気爆発により衝撃波を発生させることができる放電装置を提供する。【解決手段】導電性液体が充填された圧力容器と、前記圧力容器の導電性液体中に所定距離を離間して配設された第１放電電極及び第２放電電極と、前記第１放電電極と前記第２放電電極とに所定電圧を印加する外部スイッチを有する電源部と、を備え、前記第１放電電極と前記第２放電電極との電極間を極細導体で接続し、前記電源部の外部スイッチにより、前記第１放電電極と前記第２放電電極とに所定電圧を印加し、前記極細導体に所定電圧が導通する液中放電による導電性液体の水蒸気爆発によって衝撃波を発生させることを特徴とする放電装置とした。【選択図】図１
