第一章 概述

微机继电保护测试仪是近十年来发展起来的一个新型智能化测试仪器，以前的继电保护试验工具主要是用调压器和移相器组合而成，体积笨重，精度不高，已不能满足现代微机继电保护的校验工作。随着科学技术的不断发展，微机继电保护已广泛运用于线路保护，主变差动保护，励磁控制等各个领域，变电站综合自动化已成为主流。所以，微机继电保护测试仪，必将成为现代继电保护工作人员的必不可少的试验工具。

现代微机继电保护测试仪可分为两种形式，一种是采用传统的OCL功放，体积大，重量在25Kg左右，比较笨重，功放管工作在放大区，时间长了容易损坏，且动态范围窄，精度不高。另一种是采用开关电源，功放采用数字功放，体积小，重量轻，效率高，是继电保护测试仪的发展方向。HD300E继电保护测试仪是在总结国内外同类产品优缺点的基础上，广泛听取用户意见，充分运用现代微电子技术和电力电子技术而实现的一种新型小型化微机继电保护测试仪，它采用国际流行的DSP和开关放大器技术，单机独立运行功能已十分强大，再配以PC软件，使其能联接电脑运行，功能锦上添花，而其体积和重量只有传统测试仪的一半，先进的设计理念使该款测试仪达到了国际先进水平。 测试仪的发展从单相发展到三相，从三个机箱发展到单机箱，现已是单机箱六相配工控机的结构，HD300E六相继电保护测试仪符合这一发展趋势，已进入国内高端测试仪之列，在国内处一定的领先地位。
