Qu'est-ce que la capacit\u00e9 nominale?<\/h1>\n

\"\"<\/a><\/p>\n

Capacit\u00e9 nominale se r\u00e9f\u00e8re \u00e0 la valeur conventionnelle de la puissance apparente sous le robinet. La capacit\u00e9 indiqu\u00e9e sur la plaque signal\u00e9tique du transformateur est la capacit\u00e9 nominale, repr\u00e9sentant la situation lorsque le robinet interrupteur est \u00e0 la principale du robinet, c'est \u00e0 dire, le produit de la puissance nominale tension \u00e0 vide, le courant nominal, et de la phase correspondante facteur. Pour les trois phases de transformateurs, de la capacit\u00e9 nominale est \u00e9gale \u00e0 \u221a3 fois la puissance nominale \u00e0 vide tension de ligne de temps de la valeur nominale du courant de ligne, g\u00e9n\u00e9ralement exprim\u00e9e en kVA ou MVA. La capacit\u00e9 nominale est la capacit\u00e9 maximale qui peut \u00eatre continuellement imprim\u00e9e tout au long de cette ensemble de la dur\u00e9e de vie normale, comme les 30 ans. La r\u00e9elle capacit\u00e9 de sortie d\u00e9pend de la tension sous charge (dans le cas de charge inductive, la tension sous charge est inf\u00e9rieure \u00e0 la puissance nominale tension \u00e0 vide), le courant nominal, et de la phase correspondante facteur.<\/p>\n

Pour une tension \u00e0 vide de r\u00e9gulation de transformateurs, de la capacit\u00e9 nominale peut \u00eatre d\u00e9livr\u00e9e lorsque le robinet est en position \u00e0 -5%, et la puissance nominale capacit\u00e9 de production doit \u00eatre r\u00e9duite lorsque le robinet est en position en dessous de -5%. Pour la tension de charge r\u00e9glementant les transformateurs, les fabricants pr\u00e9cisent g\u00e9n\u00e9ralement que la capacit\u00e9 nominale peut encore \u00eatre d\u00e9livr\u00e9e \u00e0 l'-10% appuyez sur position, tandis que la puissance nominale de la capacit\u00e9 doit \u00eatre r\u00e9duite lorsque le robinet est en position au-dessous de -10%.<\/p>\n

Le contenu ci-dessus concernent essentiellement constant de flux magn\u00e9tique de tension-r\u00e9gulation de la puissance des transformateurs ou des transformateurs de distribution. Pour la variable de flux magn\u00e9tique \u00e0 tension de r\u00e9gulation de l'appareil de chauffage \u00e9lectrique de transformateurs ou de redresseur de transformateurs, de la capacit\u00e9 nominale repr\u00e9sente la capacit\u00e9 maximale de production, mais dans la plupart appuyez sur les positions, la capacit\u00e9 de production est inf\u00e9rieure \u00e0 la capacit\u00e9 nominale.<\/p>\n

Pour les trois phases de transformateurs, de la capacit\u00e9 nominale est \u00e9gale \u00e0 \u221a3 fois la puissance nominale \u00e0 vide tension de ligne de temps de la valeur nominale du courant de ligne, g\u00e9n\u00e9ralement exprim\u00e9e en kVA ou MVA. La capacit\u00e9 nominale est la capacit\u00e9 maximale qui peut \u00eatre continuellement imprim\u00e9e tout au long de cette ensemble de la dur\u00e9e de vie normale, comme les 30 ans. La r\u00e9elle capacit\u00e9 de sortie d\u00e9pend de la tension sous charge (dans le cas de charge inductive, la tension sous charge est inf\u00e9rieure \u00e0 la puissance nominale tension \u00e0 vide), le courant nominal, et de la phase correspondante facteur.","breadcrumb":{"@id":"https:\/\/www.lstransformer.com\/es\/what-is-rated-capacity\/#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.lstransformer.com\/es\/what-is-rated-capacity\/"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/www.lstransformer.com\/es\/what-is-rated-capacity\/#primaryimage","url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742011071988424.png","contentUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742011071988424.png","width":370,"height":276},{"@type":"BreadcrumbList","@id":"https:\/\/www.lstransformer.com\/es\/what-is-rated-capacity\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"\u9996\u9875","item":"https:\/\/www.lstransformer.com\/"},{"@type":"ListItem","position":2,"name":"What is rated capacity?"}]},{"@type":"WebSite","@id":"https:\/\/www.lstransformer.com\/#website","url":"https:\/\/www.lstransformer.com\/","name":"LS transformateur de puissance, r\u00e9acteur de Ligne \u00e0 Haute tension transformateur d'Huile de transformateur immerg\u00e9-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","description":"","publisher":{"@id":"https:\/\/www.lstransformer.com\/#organization"},"potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/www.lstransformer.com\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"fr-FR"},{"@type":"Organization","@id":"https:\/\/www.lstransformer.com\/#organization","name":"LS transformateur de puissance, r\u00e9acteur de Ligne \u00e0 Haute tension transformateur d'Huile de transformateur immerg\u00e9-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","url":"https:\/\/www.lstransformer.com\/","logo":{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/www.lstransformer.com\/#\/schema\/logo\/image\/","url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/06\/cropped-7e09bd7bad9c830e0d75b8487b0d77c3-1.webp","contentUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/06\/cropped-7e09bd7bad9c830e0d75b8487b0d77c3-1.webp","width":760,"height":202,"caption":"LS power transformer, Line reactor, High-voltage transformer, Oil-immersed transformer-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD"},"image":{"@id":"https:\/\/www.lstransformer.com\/#\/schema\/logo\/image\/"}},{"@type":"Person","@id":"https:\/\/www.lstransformer.com\/#\/schema\/person\/674089c15f4857c19a997f886816d289","name":"369703005","image":{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/secure.gravatar.com\/avatar\/dcaa0e47cd7b6c99ffdd80f5772032ed2d2591b5b8e7b905e5fd87a850954248?s=96&d=mm&r=g","url":"https:\/\/secure.gravatar.com\/avatar\/dcaa0e47cd7b6c99ffdd80f5772032ed2d2591b5b8e7b905e5fd87a850954248?s=96&d=mm&r=g","contentUrl":"https:\/\/secure.gravatar.com\/avatar\/dcaa0e47cd7b6c99ffdd80f5772032ed2d2591b5b8e7b905e5fd87a850954248?s=96&d=mm&r=g","caption":"369703005"},"url":"https:\/\/www.lstransformer.com\/fr\/author\/369703005\/"}]}},"_links":{"self":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1446","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/comments?post=1446"}],"version-history":[{"count":5,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1446\/revisions"}],"predecessor-version":[{"id":6491,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1446\/revisions\/6491"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/media\/2210"}],"wp:attachment":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/media?parent=1446"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/categories?post=1446"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/tags?post=1446"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
