【 摘 要 】

This article considers questions of overhead high-voltage lines working capacity and ways of its improving reliability. Influence of different factors especially climatic on overhead line condition is shown. Zoning plan of the Russian Federation on annual average duration of thunderstorms in hours is presented. Also, it shows data on numbers of thunderstorm activity intensity on the territory of the Republic of Mari El over a period of observation from 2007 to 2016 years. Statistic data on number of overhead line shutdowns in thunderstorm periods from 1985 to 2010 years. For estimation of working capacity of device and elements of distribution mains weather two-factor models are presented. Key reasons of damage of overhead electric lines elements are shown, besides, data on shutdown of overhead lines because of pin-insulators damages and cords on the territory of the Republic of Mari El over a period from 2007 to 2016 years are illustrated. Maintenance work system of overhead lines that accepted in operation are considered. On the results of reasons of overhead lines breakdown analysis it was found that most of overhead lines emergency shutdowns are caused by nature and climate effects that depend on conditions of usage, high quality conduction routine-preventive repairs, consequently on technical staff qualification etc. Service policy considering nature and climate factors influence, material-and-technical support by modern instruments and equipment, rational service and timely preventive measures implementation was designed.
