With the global power industry's rapid development,Low-voltage electrical appliances and electrical control technology in the industrial and agricultural production and people's daily lives more and more extensive application of. In order to ensure the normal production and life,In the distribution circuits, motor or other electrical equipment in the access of a circuit breaker used for the automatic cut off Fault line to protect the equipment will not have to set point, short-circuit, and other effects of damage.
The traditional circuit breaker only simple protection , lack of visual observation and not enough flexibility in the use. So we set up this topic, research Low-voltage circuit breakers on the hardware and software, use intelligent in the circuit breaker, On the one hand, the same circuit breaker can achieve multiple functions, including tripping Over-under voltage protection, short circuit protection tripping, high-temperature protection and parameters, and other functions; on the other hand it can achieve the central control computer and a two-way communication intelligent Monitoring, protection, information network system, so that the original circuit breaker from the basic protection to the development of intelligent protection.
