摘要
电弧故障保护电器是一类能够实现故障电弧检测并切断故障线路的保护电器,确保其动作的可靠性是产品生产与应用的重要课题。针对电弧故障保护电器的动作特性验证实验,本文介绍了国内外相关标准,阐述了标准UL 1699—2017与国家标准GB/T 31143—2014在产品定义、适用范围、产品功能要求等内容上的差异,重点分析电弧故障检测实验内容、电弧故障模拟发生装置的技术要求,为电弧故障的实验研究和电弧故障检测设备的设计奠定基础。
Arc fault detection device is a newly developed protector which can detect fault arc and cut off the failure circuit.Ensuring the reliability of its operation is an important issue in the production and application.The relevant domestic and foreign standards are introduced to study the action characteristic verification tests of arc fault detection device.Comparison analysis has been put on the differences between the standard UL 1699—2017 and national standard GB/T 31143—2014 in product definition,scope of application and functional requirements of products.The experimental content of arc fault detection and the technical requirements of arc fault simulation device are analyzed emphatically that would lay a foundation for the experimental studies of arc fault and the design of arc fault detection equipment.
