Quel est l'objectif du test du rapport des tours du transformateur ?<\/strong><\/p>\n\n\n\n

Le test du rapport des tours du transformateur est utilis\u00e9 pour d\u00e9terminer le nombre de tours d'un enroulement d'un transformateur par rapport au nombre de tours des autres enroulements de la m\u00eame phase du transformateur. Le test de polarit\u00e9 du transformateur d\u00e9termine les relations vectorielles des diff\u00e9rents enroulements du transformateur.<\/p>\n\n\n\n

Pourquoi devons-nous tester le rapport de transformation d'un transformateur ?<\/h1>\n\n\n\n

Par exemple, dans un r\u00e9seau \u00e9lectrique, deux transformateurs sont g\u00e9n\u00e9ralement exploit\u00e9s en parall\u00e8le, et les deux transformateurs doivent avoir la m\u00eame phase, et la diff\u00e9rence de phase entre les deux transformateurs ne peut pas d\u00e9passer 0,5%, sinon une grande circulation se produira entre les deux transformateurs, et la perte du transformateur augmentera, ce qui conduira facilement \u00e0 des d\u00e9fauts, tels que le court-circuit ou le circuit ouvert de l'enroulement, la rupture ou la combustion de l'enroulement, et la d\u00e9formation de l'enroulement. Ces d\u00e9fauts affectent la fiabilit\u00e9 des enroulements du transformateur. La d\u00e9t\u00e9rioration des param\u00e8tres du rapport de transformation peut refl\u00e9ter certains d\u00e9fauts du transformateur. Le test du rapport de transformation du transformateur permet de d\u00e9tecter les courts-circuits entre les enroulements, les circuits ouverts des enroulements, les claquages et les br\u00fblures des enroulements, ainsi que d'autres d\u00e9fauts ; la m\u00e9thode est simple, de sorte que le transformateur appara\u00eetra avant le fonctionnement ou appara\u00eetra.<\/p>","protected":false},"excerpt":{"rendered":"
