Abstract—

Experimental results on the effect of the length of the discharge gap during an underwater spark discharge and the length of the metal conductor at its underwater electrical explosion are presented. In both cases, the dependence of the pressure wave amplitude on the length of the interelectrode gap or the conductor length has an optimum at which the pressure wave with a maximum amplitude is generated. In this respect, it is necessary to realize the modes with an optimal value of the length of the interelectrode gap, which ensures the efficient electrodischarge effect on the object treated. During the underwater spark discharge, it also allows realizing the mode close to critical, which positively affects the resource and lifetime of the electrodischarge equipment. It is shown that the change in the length of the metal conductor at its underwater explosion with the invariable parameters of the discharge circuit changes the mode of the underwater electrical wire explosion.

水下火花放电过程中电极间间隙的长度和导体在水下电爆炸过程中的长度对所产生压力波振幅的影响

摘要-

给出了在水下火花放电期间放电间隙长度的影响以及金属导体在水下爆炸时的长度的实验结果。在两种情况下，压力波振幅对电极间间隙的长度或导体长度的依赖性具有最佳的，在该最佳处产生最大振幅的压力波。在这方面，有必要实现具有电极间间隙的长度的最佳值的模式，这确保对被处理物体的有效放电效果。在水下火花放电期间，它还允许实现接近临界的模式，这对放电设备的资源和寿命产生了积极的影响。
