Study On The Mechanism Of The New Arcing Gap Lighting Protectiong To A Reliability

To solve the problem and lightning arcing reliability of power supply, this paper first clear arcing lightning protection main function of the object is industrial frequency arc. Therefore, this article first introduces the generation and out of the arc principle. Then from gas discharge, lightning overvoltage conditions such as the gas ionization analysis process to analyze the characteristics, arc from the characteristics of ac arc arc went to analyzing ac some basic principles and methods for the arcing conventional arcing mechanism study provide effective theory basis.This article through the theoretical analysis and experiment, the method of combining from how to suppress arcs to research the arc condition of the characteristics and industrial frequency free-wheeling arc properties and through industrial frequency arc experiment and arcing experiment to analysis the principle of validation arcing lightning protection for arcing mechanism research provide effective experimental analysis.Using high-speed camera respectively from different angles filmed arcing experimental arcing process. From the voltage and current waveform figure studies of time and voltage electric current extinguishes the relationship. Through careful observation repeatedly arcing experimental pictures and data, draw arcing lightning protection process, the macro movement characteristics arc for arcing lightningproof provides a good basis.Through the advantages and disadvantages of traditional lightning protection measures are analyzed, and compared with arcing lightning protection, adopting the combination way to improve the effect of lightning protection, take proper measures to improve the power supply reliability.
