Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, and in particular to a spliced ​​circuit breaker with a unified control function. Background Art

[0002] A circuit breaker is a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They can automatically cut off the circuit when they have serious overloads or short circuits, undervoltage and other faults. Their function is equivalent to a combination of fuse-type switches and over- and under-temperature relays, and generally no parts need to be changed after disconnecting the fault current.
