Abstract: Aiming at the 28-Day test requirements of circuit breakers for over current protection for household and similar installations, this paper proposed to use the reactive load instead of resistance load, designed a kind of electric current generator device based on the intelligent technology and gave the design flow of hardware and software of the system. The new system used two-stage adjust regulation mode, which not only met both the test requirement, but also reduced the load capacity. The equipment integrated measurement, control and communication, with the characteristics of high reliability, low cost, high automaticity and convenient usage etc.
Key words: miniature circuit breakers; temperature rise; 28-Day; intelligent; detection
