Piston type transduction electrode

Abstract

The invention discloses a piston type transduction electrode, comprising a housing, an insulator, an outer cap (4) and a high voltage electrode (9). The high voltage electrode (9) is positioned inside the insulator; the insulator is sleeved in the housing; the outer cap (4) covers above the housing and the insulator; in the housing, a middle cylinder (2) sleeves an upper part of an outer cylinder (1); the middle tube (2) can be moved up and down under an external force; the upper limit of the movement is the lower rim of a fixed member (3);in the insulator, an insulation cylinder (6) sleeves in the upper segment of the middle cylinder; the insulation sleeve (8) is arranged in the lower segment of the outer cylinder (1) and in the middle segment and the lower segment of the middle cylinder (2) in a sleeved manner; a high voltage electrode (9) is arranged inside the insulation cylinder (6); the high voltage electrode (9) consists of a plurality of single-core insulation cables; the center conductors of the plurality of cables are connected through a busbar; and the busbar is connected to a high voltage terminal of an external power source through a stud; and the plurality of single core insulation cables are arranged in a conducting solution which fills up a sealing space defined by the insulator.

Description

technical field [0001] The invention relates to a pulse discharge electrode, in particular to a transduction electrode for converting discharge energy in water into pulse sound energy or seismic wave energy. Background technique [0002] Pulse discharge technology in water has been widely used in the fields of industry, science and medicine, and the electric spark source is one of its potential applications in the field of seismic exploration. The principle of the electric spark source is: use a large current discharge to form a huge shock wave in the water, the shock wave propagates through the liquid and the surface layer, and receives the seismic wave signal through the geophone, and then obtains the local geological features. Traditional EDM sources must rely on large water bodies. For example, marine EDM sources discharge in vast seawater, while land EDM sources also need to dig wells and inject water in the exploration site, and then place electrodes into the well wate...
