FIELD: power engineering. SUBSTANCE: inventions group relates to the field of power engineering, namely to methods for repairing a string of disc insulators, rod polymer insulators for overhead power lines. The method consists in diagnosing a string of insulators and restoring the standardized parameters of the mechanical and electrical strength of the string. The method is carried out by replacing the insulator with a repair insulator made in the form of a rod polymer insulator, and depending on the length of the garland, the insulator located closer to the traverse or closer to the current-carrying wire is replaced. The repair insulator contains a support rod, end fittings and a polymer protective sheath. The end fittings are rigidly fixed by crimping at the ends of the bearing rod with the formation of a free surface of the rod between them of at least 9 mm, and the value of the diameter of the bearing rod is taken to be at least a quarter of the construction length of the insulator. The set of repair insulators is made with a constant construction length and a variable length of the free surface of the rod between the end fittings of each of them. The set is formed on the basis of the condition of obtaining at least one and a half times the breakdown voltage value for each subsequent insulator in the set. EFFECT: reducing the complexity of repairs while improving the characteristics of the repaired string of insulators. 5 cl, 1 dwg, 1 tbl РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 755 653 C1 (51) МПК H01B 17/04 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК H01B 17/04 (2021.08) (21)(22) Заявка: 2021105742, 05.03.2021 (24) Дата начала отсчета срока действия патента: Дата регистрации: Приоритет(ы): (22) Дата подачи заявки: 05.03.2021 (56) Список документов, цитированных в отчете о поиске: RU 2620021 C1, 22.05.2017.

136,627. Pollak, J. E., (Fabbrica Isolatori Livorno). Dec. 17, 1918. Insulators.-Composite high-tension insulators comprise semi-spherical cups of uniform thickness which are either nested together as shown in Fig. 3, or arranged as shown in Fig. 2, and the connecting cement reinforced by metal netting A and wire coils B. A metal socket G surrounds the porcelain bodies when arranged as shown in Fig. 2, and a metal hood I when the parts are nested together.
