摘　　要：研制了一种脉冲电度表。利用传感技术,采集电能的参数,把电度表中的电能量转换为脉冲量,再经脉冲变送电路形成具有一定幅度和一定宽度的脉冲信号。可以经长传导线引入微机监控系统,形成电源智能监测仪器。也可以用无线发射机与中心监控系统联网。用软件系统计算出有功电能、视在电能、无功电能及功率因数等参数。配合其它参数的采集系统,可全面监测电力变压器的运行状态。该技术也可以应用在其它仪表设备中,完成仪表信号数字化和远距离传输。系统抗干扰能力强,是信号采集与变送技术的一项创新。在自动化技术中有较高的实用价值。A kind of pulse energy meter has been developed. It collects parameter of electric energy in sensor technology, changes electric energy volume into pulse volume, and outputs pulse signal with certain breadth and width by pulse conversion transponder circuit. The signal may be inputted into microcomputer supervisory control system by long conduction line, come into being intelligence monitor. It also may network with center supervisory control system by radio navigation. It can figure out active power, apparent energy, reactive energy and power factor parameter and so on in software system. When cooperating with other system of parameter acquisition, it may monitor totally running state of power transformer. This technology also may use in other instrument and meter to accomplish signal digitalization and in the distance transmission. This system has strong jamproof ability, is an innovation in the technology of signal acquisition and conversion transponder. It has higher utility value in automation system
