摘要
电弧故障的危害,主要是热效应和压力效应,介绍了中压开关设备内电弧故障产生效应的分析和计算方法,并应用该分析计算方法对KYN28A-12开关柜手车室门板进行了强度校核,并提出了一些防护内部电弧故障的具体措施,为IAC级开关设备的开发设计提供了参考。
Harm of arc fault is mainly caused by thermal effect and pressure effect. Introduction was made to the analysis and calculation method for the effect generated by arc fault inside medium-voltage switchgear. The analysis and calculation method was used to check the strength of handcart door-plate of KYN28A-12 switchgear and this paper raised actual measures preventing internal arc fault from taking place to provide references for IAC grade switchgear development design.
