The invention discloses an intelligent power distribution safety control system, which can give an early warning to inform a switch where a hidden danger of overheating occurs, and completely eliminate fire accidents caused by human negligence, untimely inspection and the like. The system consists of temperature sensor, temperature acquisition unit, input memory, data processor, central processing unit, graphic display processing, touch screen, communication processor, Ethernet, SMS unit, control output unit, tripping controller and air breaker The signal output by the temperature sensor installed at each metal contact of the air circuit breaker in the power distribution cabinet is collected by the temperature acquisition unit and input to the storage, data processor and comparator. The display processing, touch screen, and communication processor are used to display and control various parameters, and send over-temperature alarm information through the Ethernet and SMS unit, and trip and power off the air circuit breaker with over-temperature contacts through the control output unit .
