HIGH-VOLTAGE ELECTRODE STRUCTURE FOR ELECTROPULSE BREAK-DOWN OF CONCRETE AND REINFORCED-CONCRETE PRODUCTS Russian patent published in 1997 - IPC

FIELD: break-down of concrete and reinforced-concrete products by electric discharges. SUBSTANCE: the high-voltage electrode structure has discharge insulated rod 1, its drive 2 which are interconnected by flexible non-conducting coupling unit 3. High-voltage element 5 is connected to the output of the pulsating voltage source; connected to the rod upper part is toroid ring 4 whose outside diameter makes up at least 1.7 of the insulation diameter of discharge ring 1, and the distance between toroid ring 4 and water, with discharge insulated rod 1 lowered onto the surface of the product to be broken down, makes up at least 0.8 to 0.9 of the rod portion projecting over water, and the distance to high- voltage element does not exceed 2 cm. EFFECT: improved design. 1 dwg
