摘　　要：现阶段的核相仪工作原理是同时采集2个三相电源的电信号进行对比,以判断2个三相电源之间的相位关系。该核相方法在操作上较为繁琐,受时间和空间的影响较大,无法有效提高核相工作的效率。基于该核相背景,研制一套基于定时器计时的核相仪。该核相仪可单独采集2个三相电源的电信号,利用定时器推算出同一时间节点下2个三相电源的模拟相角值,并利用该模拟相角值对2个三相电源进行核相,能使核相工作突破时间和空间的限制,提高核相工作的效率。The current working principle of the phase meter analyzer is to simultaneously collect electrical signals from two three-phase power sources for comparison,in order to determine the phase relationship between the two three-phase power sources.This phase-determining method is relatively cumbersome in operation and is greatly affected by time and space,which cannot effectively improve the efficiency of phase-determining work.Based on this phase-determining background,develop a phase meter based on timing circuit.This phase meter can independently collect electrical signals from two three-phase power sources,use a timer to calculate the simulated phase angle values of the two three-phase power sources at the same time node,and use the simulated phase angle values to perform phase meter analysis on the two three-phase power sources.This can break through the limitations of time and space in phase-determining work and improve the efficiency of phase-determining work.
