    摘 要:低壓斷路器在研發階段需要做大量的短路試驗來驗證其在短路條件下的接通分斷能力。國家標準中定義的短路試驗操作順序為“O—t—CO—t—CO”,其中t 至少為3 min。為了縮短研發測試時間,研發了一種半自動化高效率的短路測試裝置,該裝置能有效地避開等待時間提高測試效率。給出了該裝置的結構圖并分析了其高效的工作原理。經性能測試表明,該裝置大大地提高了測試效率,其對低壓斷路器的研發有一定的意義。
    關鍵詞:小型斷路器;短路試驗;操作順序;等待時間

    Abstract: A lot of short-circuit tests are implemented to verify the short-circuit making and breaking capability during low voltage apparatus research and development. The short-circuit test operation sequence defined in national standard is “O — t — CO — t — CO ”, the waiting time is 3 minutes at least. Traditionally, a lot of samples are used to test and one test sample one time, this means needing more test time. Based on this situation, one semi-automatic high efficiency short-circuit test equipment was developed to avoid the waiting time. The structure diagram is given and principles of high efficiency are analyzed. The test result shows this equipment can improve test efficiency; it is meaningful for low voltage apparatus research and development.
    Key words: miniature circuit breaker; short-circuit test; operation sequence; waiting time
