1、高压开关微机综合保护装置软件设计高压开关微机综合保护装置软件设计 摘摘 要要 电力是国家经济建设和人民生活中不可缺少的能源， 而电力工业的发 展离不开用于输配电的高压开关设备。在电气设备运行中,经常需要监测 一些参数,比如电流、 电压、 漏电电流、 短路电流等,以保证设备正常工作。 以往高压开关综合保护装置多采用模拟电路来监测电流和电压等参数以 实现短路、过载、失压、过压、漏电等保护,其结构复杂、体积大、耗能 多。随着微机技术的飞速发展,单片微型计算机以其体积小、价格低、应 用灵活等优点在自动控制领域中得到了广泛的应用。 为了解决原有的高压 开关综合保护装置的上述问题,采用了单片机系统实时监测

2、设备运行的各 种参数,并对其进行分析、计算、处理,保证设备安全、可靠的运行。 本综合保护装置具有过载、短路、漏电(包括电流型和功率方向型) 、 监视、过压、失压、缺相等保护功能。具有微机测量和微机保护，网络通 信以及在线监测等基本功能。 概括介绍了 P89C51RB2 单片机控制的智能型 高压开关综合保护装置的特点和基本功能， 详细说明了智能型高压开关综 保装置的硬件接口电路和软件设计。该装置具有性能可靠、功耗低、体积 小、功能强的特点。 关键词：单片机;高压开关;综合保护 1 ABSTRACT： The electric power is the energy that the nation

3、al economy constucts to live medium indispensability and people, but the development of the electric power industry can not get away from to used for the high pressure switch equipments that loses to go together with an electricity. Usually need to monitor some parameters in the electricity equipmen

4、ts the movement, for example the electric current,electric voltage,electric leakage electric current,short-circuit electric current etc. work normally by promising an equipments. The high pressure switch is comprehensive before protection the device adopts emulation electric circuit much to monitor

5、current and voltage etc. parameter short-circuit with the realization, lead to carry, lose to press, lead press, electric leakage etc.protection, its structure complications, physical volume big,consume and can be many. Fly technically to develop soon along with the tiny machine, single slice microc

6、omputer its physical volume is small,the price is low,the applied vivid etc. advantage got an extensive application in the automatic control realm. For resolving an original high pressure switch comprehensive protection device of above-mentioned problem, adopted a single slice machine system solid hour monitor various parameter of the equipments movement, and as to its carry on analysis,compute and handle, promise an equipments safety, dependable movement.
