ABSTRACT
The purpose of this research work is to study the issues of the protection of 6–10 kV lines and access ways overvoltage in the electrical networks of modern enterprises of high-energy intensity, as well as the search for real technical opportunities to improve the protection of power lines directly in conditions of their operation. The methodology of this scientific research is based on a combination of methods of system analysis of the principles of the functioning of electric networks of energy-intensive enterprises with an analytical study of the fundamental aspects of ensuring the protection of 6 to 10 kV lines and access ways from overvoltage. The results of the conducted scientific research indicate the relevance of the issues of ensuring the protection of lines and electrical networks of energy-intensive enterprises from overvoltage and the need to develop special technical devices to ensure the proper level of such protection in real conditions. The results and conclusions of this research work are of significant importance for developers and designers of electric networks of enterprises with increased energy capacity, as well as for employees of various power supply systems who, by their occupation, face the tasks of servicing electric networks, which include lines and access ways with specified operating voltage parameters and ensuring the proper level of safety and practical use of these electric networks of energy-intensive enterprises.

Celem pracy badawczej jest zbadanie problematyki ochrony linii 6–10 kV i przepięć w miejscach dostępu w sieciach elektroenergetycznych nowoczesnych przedsiębiorstw o dużej energochłonności, a także poszukiwanie realnych technicznych możliwości poprawy ochrony linii elektroenergetycznych bezpośrednio w warunkach ich eksploatacji. Metodologia niniejszych badań naukowych opiera się na połączeniu metod analizy systemowej zasad funkcjonowania sieci elektroenergetycznych przedsiębiorstw energochłonnych z analitycznym badaniem podstawowych aspektów zapewnienia ochrony linii od 6 do 10 kV oraz miejsc dostępu do nich od przepięcia. Wyniki przeprowadzonych badań wskazują na istotność zagadnień zapewnienia ochrony linii i sieci elektrycznych przedsiębiorstw energochłonnych przed przepięciami oraz konieczność opracowania specjalnych urządzeń technicznych zapewniających właściwy poziom tej ochrony w warunkach rzeczywistych. Wyniki i wnioski z tej pracy badawczej mają istotne znaczenie dla wykonawców i projektantów sieci elektrycznych przedsiębiorstw o podwyższonej energochłonności, a także dla pracowników różnych systemów zasilania, którzy z racji wykonywanego zawodu mają do czynienia z zadaniami serwisowania sieci elektrycznych obejmujących linie o określonych parametrach pracy oraz odpowiadają za odpowiedni poziom bezpieczeństwa i praktycznego użytkowania tych sieci elektrycznych przedsiębiorstw energochłonnych.
