摘 要：為了保證斷路器脫扣特性試驗的輸出電流為正弦電流，對該試驗方法進行了研究，并提出了一種基于LabVIEW 的虛擬檢測技術(shù)，以PIC18F4620 單片機為核心的選相裝置的設(shè)計思路。給出了軟硬件設(shè)計過程，將設(shè)計出的裝置應(yīng)用于斷路器的脫扣極限和特性試驗，較好地消除了電流中的非周期分量，且實現(xiàn)了具有控制、數(shù)據(jù)采集、數(shù)據(jù)處理、波形顯示等功能的脫扣特性檢測。

Abstract: In order to ensure that the output current is sinusoidal in circuit breakers tripping characteristics testing, this paper researched the testing method, raised the design idea of LabVIEW virtual detection technology with the microcontroller PIC18F4620 as the core phase selection device and gave the design process of software and hardware. The designed device was applied in the circuit breakers tripping limitation and characteristics testing to nicely eliminate the aperiodic component of currents, realizing the tripping characteristics testing with the functions of control, data acquisition, data processing and waveform display.
Key words: circuit breaker; tripping characteristics; sinusoidal current; LabVIEW virtual detection technology; phase selection synchronous switch
