基于FPGA的矿井低压选择性漏电保护装置的设计

Design of Selectivity Electric Leakage Protecting Device for Mine Low Voltage Based on FPGA

在介绍漏电保护原理的基础上,提出一种基于现场可编程门阵列(FPGA)的选择性漏电保护装置的设计。根据FPGA模块化设计思想,把系统分解为各种功能不同的模块,再分模块进行逻辑功能设计,相比以往的漏电保护装置,该装置能提高漏电保护的准确性和快速性。

On the basis of introducing the electric leakage protection principle, proposes one design of selectivity electric leakage protecting device based on field programmable gate array （FPGA）. According to the design ideas of FPGA module, dividing the protection system into different modules, and designing the functions for different modules. Comparing with the previous leakage protecting devices, the accuracy and validity have a significant improvement.
