摘要
提出基于单片机的漏电保护智能化技术。通过漏电电流计算模型得到最大漏电电流及所在相线,建立三级漏电保护模型,实现选择性保护,并设计了智能漏电保护器硬件结构,介绍了软件所实现的功能。运行结果表明,该装置可提高漏电保护的可靠性和有效性。
An intelligent technology of leakage current protection based on MCU was presented. The maximum leakage current and corresponding phase were gotten via leakage current model. Three-section protection model was established to implement selective protection. The hardware fame of leakage current protector was designed and the function of software was introduced. The running result shows that the protector can improve reliability and validity for leakage current protection.
