Extinguishing light arc between two electrodes involves combination of spark movement by magnetic field and gas releasing plastic; spark is extinguished in electrode region containing plastic

摘要

The method involves a combination of spark movement by magnetic field and a gas releasing plastic. The spark is extinguished in a region of the electrodes in which the plastic is located. The plastic releases the gas when it interacts with the spark, inducing a gas flow that forces the spark to extinguish at the natural current null crossing of a half wave. The method involves a combination of spark movement by magnetic field and a gas releasing plastic. The spark is extinguished in a region of the electrodes in which the plastic is located. The plastic releases the gas when it interacts with the spark, whereby a gas flow is induced that forces the spark to extinguish at the natural current null crossing of a half wave. The magnetic field moves the spark to maintain it close to the plastic near the natural null crossing of the half wave with decreasing Lorentz force in a defined period. Independent claims are also included for a circuit breaker or power switch for rapid switching of alternating currents.
