摘要
介绍一种新型微机型自动准同期测试装置的原理、结构和应用。该装置采用先进的检零、纠偏以及功率电子电路等系列新技术,可生成范围可调的匀速、匀变速和随机等三类滑差信号,适用于国内外各种自动准同期装置的性能调试及合闸误差角、导前时间、滑差周期等参数的自动检测,并具有并列监视、表计校正、标准频率输出等多种功能。
A novel microprocessor based calibrator for automatic synchronizers along with its principle,structure and application are introduced in this paper.Several new technologies are adopted in the design of the calibrator,such as zero phase detection,error compensation,electronic circuit with high power output,etc.The device is able to produce adjustable three kinds of slip signals,i.e., constant slip,linear variable slip and random slip signals,which are suitable to be used for the performance adjustment for various kinds of synchronizers.It can automatically detect the parameters of synchronizers such as closing phase angle,advanced time and slip period,and possesses several additional functions such as monitoring synchronizing operation,calibrating for frequency meters and generating standard frequency signals.The remarkable technological performance is superior to the traditional synchronizer calibrators.
