Review of Research on Low Voltage DC Series Fault Arc
DC series fault arc has high concealment and difficult detection,which is an important cause of fire in low voltage DC system.The model of low voltage DC series fault arc,arc characteristics and detection methods,detection standards and devices are reviewed mainly.Based on the arc simulation model is used to understand the arc evolution process,the principle,application range and limitations of the common fault arc model are analyzed.Based on the physical and electrical signal features geuerated by fault arc,construction and detection methods the advantages and disadvantages of different feature detection methods are exponded.Finally,the relevant standards of DC series fault arc are interpreted,and the current research status and shortcomings of the test platform and products are discussed.The future research direction of low voltage DC fault arc is prospected.
