Electrical protection circuit breaker
An electrical protection circuit breaker comprises a microprocessor chip part, a circuit breaker part connected between a power line and a power supply, a temperature detection part for detecting a temperature of the power line, a current detection part for detecting a current of the power line, and a voltage detection part for detecting a voltage of the power line. A memory of the microprocessor chip part stores a data collection S=f(temp, I, V, Δtime), wherein S represents a diameter of the power line, temp represents the temperature, I represents the current, V represents the voltage, and Δtime represents a set time period. The microprocessor chip part matches electronic data of real-time temperature changes, electronic data of an import current, and electronic data of a voltage with data sets in the data collection, and sets a corresponding safety protection current according to matching results.
