1、前言在电力系统中,由于微机技术的开发及应用,从而使电力系统中的继电保护和自动控制技术产生了质的飞跃,一些新产品新技术得到了广泛应用,这就与旧有系统产生了一定的矛盾。例如节能型光电信号的应用,就与传统的机电式(包括集成电路式)冲击信号继电器的应用产生矛盾,由于节能型光电信号装置工作电流小(一般不大于30mA),势必降低冲击信号继电器的启动电流,容易造成冲击信号继电器误动作。本文以我公司开发的FXZ-1型微机闪光报警器为例,介绍微机技术在信号报警装置中的应用。该装置具有可靠性高、抗干扰能力强,操作简单、安装方便、维护
1, Preface In the power system, due to the development and application of microcomputer technology, there has been a qualitative leap in relay protection and automatic control technology in the power system. Some new products and new technologies have been widely used, The system has produced some contradictions. For example, the application of energy-saving optical signals contradicts the application of traditional electromechanical (including integrated circuit) impact signal relays. Since the operating current of the energy-saving optical signal device is small (generally not more than 30mA), the impact signal relay Start current, easily lead to the impact of signal relay malfunction. In this paper, my company developed FXZ-1 microcomputer flash alarm, for example, introduces the microcomputer technology in the signal alarm device. The device has high reliability, anti-interference ability, simple operation, easy installation, maintenance
