Intelligent circuit breaker combined device

The invention provides an intelligent circuit breaker combined device. A current detecting piece is arranged in a circuit breaker. The current value of a circuit in the circuit breaker is obtained through the current detecting piece and then sent into a controller of an intelligent control device on one side of the circuit breaker, and the controller makes a judgment according to the received current value, and controls and starts an action mechanism to drive the circuit breaker to be released when the current value is in an overload state for a period of time. Because the current value of the circuit in the circuit breaker is directly tested and the controller is used for intelligent control, the problem that a thermal releaser is prone to fails caused by the external environment air temperature influences is solved. Meanwhile, due to the fact that the thermal releaser is omitted, the internal resistance of the circuit breaker is greatly reduced, and the power consumption and the heating amount of the circuit breaker are reduced. In addition, the controller is independently arranged in the intelligent control device outside the circuit breaker, the problem that a controller can not be put in a narrow space of a circuit breaker is solved, and meanwhile it can be avoided that the work of a controller is influenced by strong current.
