Investigation of Intelligentized Protector for Three Phase Motor

本文介绍 80 5 1单片机在三相电动机继电保护中的应用。利用功能强大的单片机技术 ,完成智能保护器的硬件电路设计 ,并编制完整的电动机保护程序 ,最终实现过压、欠压、过载等多种保护功能。

This paper introduces the application of the 8051 singlechip in motor protection. Using the powerful singlechip technology, the hardware design of the intelligentized protector is completed and the whole protective program is worked out. Several protective functions, such as over voltage, lack of voltage and over load are finally achieved.
