Electrode system of electrohydraulic downhole device (versions) Electrode system contains positive and negative electrodes arranged coaxially opposite each other in metal housing with openings located opposite interelectrode gap, current lead to positive electrode; at that, negative electrode is connected to the housing bottom; positive electrode is made in the form of massive cone directed with its top to negative electrode; in the cone top there fixed is a tip from erosion resistant metal; insulating coating is applied to side surface and bottom of cone of positive electrode and current lead to it; housing is made so that cone bottom of positive electrode can be borne against it. As per the first version of the proposed device the negative electrode is made in the form of a rod; side surface of negative electrode, which faces the housing, is coated with insulating material; at that, diameter of projecting part of negative electrode is equal to or is less than tip diameter of positive electrode. As per the second version of the proposed device the negative electrode is made in the form of a cone or semi-sphere, the tope or pole of which faces the positive electrode; the whole surface of negative electrode, which faces positive electrode, is coated with insulating material; tip of positive electrode is located near or touches the insulator of negative electrode. |

Method and device to develop high and ultrahigh pressures in liquid Application: for electrohydraulic treatment of various materials. The method consists in execution of a preliminary electric discharge inside a liquid volume contained in an open water reservoir or a closed reservoir, at least between one of working electrodes and an auxiliary electrode and subsequent main pulse electric discharge between two working electrodes. At the same time the preliminary discharge is executed as an electric corona of AC or DC voltage. Besides, the polarity of voltage of corona's preliminary discharge (voltage at the auxiliary electrode) is set as opposite to the voltage of the main electric discharge. |
