摘 要：針對(duì)家用及類似場(chǎng)所用過電流保護(hù)斷路器的28周期試驗(yàn)要求，提出了用無功負(fù)載代替電阻負(fù)載的方法，并設(shè)計(jì)了一種基于智能化技術(shù)的電流發(fā)生裝置。給出了該系統(tǒng)的軟硬件設(shè)計(jì)流程，新的系統(tǒng)用兩級(jí)調(diào)節(jié)方式既滿足了試驗(yàn)要求，又減少了負(fù)載容量。設(shè)備集測(cè)量、控制和通信于一體，具有可靠性高、成本低、自動(dòng)化程度高及使用方便等特點(diǎn)。

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
