Abstract

The invention relates to an impulse discharge electrode, which comprises a high-voltage electrode (1), a low-voltage electrode (2), an insulated sleeve (3), and a reflector (4). Wherein, said four parts both use coaxial structures; the high-voltage electrode (1) is a round rod, whose outer part is mounted with an insulated sleeve; the high-voltage electrode (1) and the insulated sleeve are connected by screw or fixed together; the outer left section of insulated sleeve is sheathed with a tube low-voltage electrode (2) while the right section is sheathed with a cylinder reflector (4) with central hole; the insulated sleeves have outer screws; the low-voltage electrode (2) and the central hole of cylinder reflector (4) have inner screws; the left end surface of cylinder reflector (4) is a inward concave semi-ellipsoid; the cylinder reflector (4) is connected to the insulated sleeve; the end of high-voltage electrode (1) is at the focus of semi-ellipsoid. The invention has simple structure, better discharge stability and repeated property, with long service life and high electric sound transform efficiency.

Description

technical field

[0001] The invention relates to an electroacoustic conversion device, in particular to a device for converting electric energy into pulsed acoustic energy in the field of high-voltage pulse discharge. Background technique

[0002] The hydroelectric effect is a new subject developed in the 1950s. It was proposed by Youtekin (Л.А.ЮТКИН.) "The Hydroelectric Effect" (Science Press, 1962) and first applied to it Stamping, crushing and sand cleaning of castings, etc. It is a general term for physical effects such as heat, light, force, and acoustics generated during high-voltage pulse discharge in a liquid medium. Its physical essence is the high-speed conversion of energy, that is, electric energy is directly converted into heat, light, force, sound, etc. form of energy.

[0003] The electrohydraulic effect has broad application prospects in many fields of the national economy, such as electrohydraulic forming, petroleum seismic exploration, extracorporeal shock...
