| In view of the hazards in recent years and bad weather conditions on the EHV transmission line,especially the serious damage to the beginning of 2008 ice disaster brought to the power system,this paper,according to the transmission line to the anti icing,anti icing flashover is analyzed.Each stage from transmission line anti icing,anti icing,ice and snow preventionstage includes the effective early warning prevention,especially the application of onlinemonitoring system,how to de ice ice period,focusing on the analysis of the efficacy of new iceremoving deicing robot,fault and the problems of the ice covered how to study transformation of the line grid icingequipment,powerflashover and postthawing processleads to how to take effective preventive measures,the icing hazards and prevention and control of the whole process of elimination to conduct a comprehensive research and analysis,put forward thescheme and the methods of antiicing and deicingflashover,and the method is proposed for the analysis of more detailed.In this paper,the combination of theory and practice,combining with the practical workexperience,through theoretical analysis and case illustrates the method to combine the fact,vividly and makes a detailed description analysis and of icing hazards,and puts forward someconstructive suggestions,I hope this article can provide some reference for transmission lineicing work. |
