Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker which is convenient to maintain. 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 devices above 3kV generally considered high-voltage. Circuit breakers are 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-voltage relay. Furthermore, interrupting fault current generally requires no component changes. They have gained widespread application. Power distribution is a crucial link in the generation, transmission, and use of electricity. Power distribution systems include transformers and various high- and low-voltage electrical equipment. Low-voltage circuit breakers are widely used.
