摘要

许多关于电弧闪光事件的文章大多都只有一个焦点。本文通过对中压金属铠装开关柜各种消弧技术的时间/距离分析,开阔了视野。KEMA- Powertest, Inc .提供的IEEE C37.20.7实际测试数据为读者提供了使用最新电弧消减拓扑混合的标准金属外壳开合设备外壳内开发的压力的真实快照。比较了三种常用的用时间大小逼近边界来处理电弧闪光的技术。本文还通过对电弧的产生以及设备和人员可能遇到的压力损害的介绍性理解,解决了与中压开关设备内电弧相关的现象。

Collaborative arc flash management solutions in medium voltage switchgear
Many articles have been written about arc flash events mostly with a single focus. This paper brings forth a wider view with time/distance analysis of different arc abatement technologies in medium voltage metalclad switchgear. The IEEE C37.20.7 actual test data from KEMA- Powertest, Inc offers the reader a true snapshot of pressures developed within standard metalclad switchgear enclosure using the latest blend of arc abatement topologies. Comparisons are made between the 3 prevalent technologies which address arc flash by time-magnitude approach boundaries. This paper also addresses the phenomena associated with electrical arcs within medium voltage switchgear by developing an introductory understanding of the generation of an arc and the pressure damages that both equipment and personnel, may encounter.
