摘　　要：在开关电器的脱扣特性实验中,为确保电流中非周期分量最小,采用精度高、使用方便的选相合闸装置很必要。本文指出目前计算机控制的断路器瞬动特性试验设备存在的问题,并提出了改进方案,设计了以80C196KC单片机作为核心的选相合闸装置。该装置应用于断路器瞬动特性试验设备中,较好地消除了试验中的暂态电流。In the tripping characteristics experiment of switch apparatus, in order that the aperiodic part of the current is the smallest, it is necessary to use a convenient phase selection making device with high accuracy. The problems existed in the current circuit breaker＇s instantaneous characteristic test equipment controlled by computer and the program for improvement were proposed. The phase selection making device was designed with a single-chip 80C196KC as its core. This device has been used on breaker＇s instantaneous characteristic test equipment, eliminating the transient current in the experiment effectly.
