某煤矿变压器综合保护技术的实践与研究

Practice and Research of Integrated Protection Technology of One Coal Mine's Transformer

简要介绍了微机变压器综合保护装置的原理、插件设计、保护功能,并分析了与传统的继电器保护装置相比所具有的优点。以某煤矿供电系统为例,重点阐述了WBH系列微机综合变压器保护装置的应用设置及端子图设计。实践表明,以Intel 16位单片机为核心的微机变压器保护装置应用于煤矿变压器的保护和测控,可大大提高煤矿供电系统运行的可靠性。

This paper briefly introduces the principles, plugin device and protection function of the integrated protection device of the microcomputer transformer and analyzes the advantages by comparing to the tradtional relay protection device. Taking one coal mine＇s power supply system for instance, the application setting of the intergrated transformers protector WBH microcomputer and are emphasized. Practice shows that the intel 16-bit microcontroller, which is the core of microcomputer transformer protection device being applied in modern coal mine transformer protection and monitoring, can improve the reliability of coal mine＇s power run-ning.
