BREAKER FOR DISCONTINUOUS JUMP CURRENT CAUSED BY INSULATOR-TO-METAL TRANSITION IN ALTERNATING CURRENT POWER SYSTEM

WIPO Patent Application WO/2023/085722

A1

The present invention relates to a development of a discontinuous jump current breaker for cutting off, in an alternating current power system having an insulating material that exhibits a nonlinear electrical property between two electrodes, alternating current power by observing a discontinuous jump current in which an insulator-to-metal transition occurs. The discontinuous jump current breaker of the present invention comprises: a setting unit for setting the size of a discontinuous jump current; a sensor unit including a metal-conducting wire (Registration No. 10-1981640), which is parallel with an alternating current power conducting wire, is positioned at a separation distance d≥0, and measures electromagnetic waves of alternating current power; an amplifier unit for amplifying an analog signal of the metal-conducting wire; an analog-digital converter unit for converting the amplified analog signal into a digital signal; a microcontroller unit, which includes a memory including a program for driving the system; and a power cutoff unit for cutting off a discontinuous jump current.
