多负载并联运行时支路串联电弧故障诊断
Branch Series Arc Fault Diagnosis in Parallel Operation of Multi Load
摘要
Abstract
In order to realize the accurate diagnosis of the arc fault in a slip road in the condition of a variety of load at the same time working,a carbon electrode arc fault experimental platform was built according to the UL 1699 and GB 14287.4 standards.Depending on the experimental results,the arc current signal is introduced into the high dimensional space by using the phase space reconstruction algorithm.Moreover,the characteristic vector of the fault arc is extracted by the volume dimension and the correlation dimension respectively.A new arc fault diagnosis method,based on the construction of arc fault diagnosis device using least squares support vector machine(LSSVM) was proposed.The research result can provide the theoretical basis for arc type electrical fire monitoring detector.关键词
