井下低压电网智能化综合保护系统的研究

Study on Intelligent Comprehensive Protective System for Underground Low-voltage Distribution Networks

在分析目前煤矿井下综合保护系统存在问题的基础上,设计了一种新型的以MSP430单片机为核心的智能化综合保护系统,本文重点分析了系统的基本保护原理,并介绍了系统的硬件和软件。现场运行表明该保护系统性能稳定,动作可靠,具有良好的应用价值。

On the basis of analyzing the problem existing in the current comprehensive protective system of underground LV switch-gears, this paper proposes a novel intelligent comprehensive protective system. The operating principle is emphatically discussed, and hardware structure ＆ sofiw .are block diagrams are introduced as well. The field experience shows that the protective system has good stability and rehability, and will be of great applied value in mining industry.
