The design of all-powerful type low-voltage
circuit breakers
Abstract: The all-powerful type low-voltage circuit breaker is a kind of switch used in power system for connecting and disconnecting the circuit as well as providing protection and controlling on all types of breakdown .This paper makes DW16 all-powerful type low-voltage circuit as an example, in detail introducing the all-powerful type low voltage break design process,including the designs of conduct electric system、kill arc system、overcurrent instantaneous releaser、lessvoltage releaser and overcurrent time-delay releaser.finally, use the software “Pro/E” to proceed 3D reallike, and use the software “ANSYS” proceed the analysis to the electromagnetic organization.
