船舶高压电力系统中弧闪的计算方案

Calculation Scheme of Arc Flash-over in Marine High Voltage Power System

船舶高压电力系统在商船上的应用越来越普遍,在此类船舶上工作的船员也将面对弧闪带来的风险。本文针对船舶高压电力系统介绍了电弧能量的计算方案,分析了不同经验公式计算结果的差异,并举例说明,对使用合适的方案进行弧闪的计算给出建议以选择合适的防电弧PPE。

The application of ship high-voltage power system in commercial ships is becoming more and more common,and the crew working on such ships will face the risk of arc flash.This paper introduces the calculation scheme of arc energy for marine high-voltage power system,analyzes the differences of calculation results of different empirical formulas,illustrates with examples,and gives suggestions on the calculation of arc flash using appropriate scheme,so as to select appropriate anti arc PPE.
