摘要
介绍了ＺＪ—０１型多功能微机在线监测的硬件部分．该部分由多路转换开关和波形数字采集装置组成，其功能分别是对变电站电气设备的绝缘参数和系统电气参数等信号进行逐一选通、数字采集，送入计算机分析、处理，为绝缘参数和系统电气参数的在线监测提供了保证．该部分电路经优化设计，在性能指标上具有很大的优越性．
The hardware of the new multifunctional on-line measuring system, model ZJ-01, is introduced in this paper. The hardware, composed of a multicircuit switch and a digital acquisition device, has great advantage in performance parameters because of the best design. The functions of the hardware arc, in turn, selecting the analog signals coming from sensors, converting the analog singals to digital signals and sending the digital signals to a microcomputer to calculate and analyze. The hardware provides guarantees for the system to measure insulation parameters and electric power parameters.
