Description

Technical Field

[0001] The present invention relates to the technical field of circuit breaker driving, and more particularly to an eddy current driving device for a high-speed circuit breaker. Background Art

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and closing, carrying, and interrupting current under abnormal circuit conditions within a specified timeframe. Circuit breakers are categorized as high-voltage and low-voltage based on their scope of use. The distinction between high and low voltage is somewhat ambiguous, with voltages above 3kV generally considered high-voltage. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. They automatically disconnect circuits in the event of severe overloads, short circuits, or undervoltage faults. Their functionality is equivalent to a combination of a fuse-type switch and an over- and under-temperature relay. Furthermore, interrupting fault current generally requires no component changes. They have gained widespread application.
