Par exemple, si un transformateur de 1000 tours dans la bobine primaire et 100 tours dans la bobine secondaire, les virages ratio de 10:1 (1000\/100).<\/p>\n<p>Les virages ratio d'un transformateur est un param\u00e8tre fondamental qui d\u00e9termine la tension de rapport de transformation. Pour un id\u00e9al de transformateur, la tension de rapport de transformation est \u00e9gale \u00e0 la se transforme ratio. En d'autres termes, si les virages ratio de 10:1, la tension dans le circuit secondaire sera un dixi\u00e8me de la tension dans le circuit primaire. Par exemple, si la tension dans le circuit primaire est de 100 V, la tension dans le circuit secondaire sera de 10 V.<\/p>\n<p>Cependant, dans le monde r\u00e9el les transformateurs ne sont pas id\u00e9ales et des pertes en raison de divers facteurs tels que la r\u00e9sistance, l'inductance de fuite et les pertes fer. Ces pertes affectent la tension de rapport de transformation et peut engendrer une diff\u00e9rence entre la tension de sortie et l'id\u00e9al de la tension de sortie pr\u00e9dite par les virages ratio. En r\u00e9sum\u00e9, les virages ratio d'un transformateur est le rapport du nombre de tours dans la bobine primaire, le nombre de tours dans la bobine secondaire. Il est calcul\u00e9 en divisant le nombre de tours dans la bobine primaire par le nombre de tours dans la bobine secondaire. Les virages ratio d\u00e9termine la tension de rapport de transformation entre les circuits primaires et secondaires, mais dans le monde r\u00e9el les transformateurs ont des pertes qui affectent le r\u00e9el de la tension de sortie.<\/p>\n<p>Les virages ratio est un param\u00e8tre important transformateur de conception et de fonctionnement. Il est utilis\u00e9 pour d\u00e9terminer la tension de rapport de transformation entre les circuits primaires et secondaires, et elle touche aussi d'autres propri\u00e9t\u00e9s du transformateur tels que l'imp\u00e9dance, le courant et la puissance. Les transformateurs ont des tours diff\u00e9rents ratios en fonction de l'application et de la tension requise rapport de transformation. Par exemple, les transformateurs ont plus de virages rapport que les transformateurs abaisseurs de tension.<\/p>\n<p>Les virages ratio peut \u00eatre mesur\u00e9e exp\u00e9rimentalement \u00e0 l'aide d'un transformateur transforme ratio de testeur.

Ils se composent de deux bobines de la plaie autour d'un noyau magn\u00e9tique, le primaire et le secondaire, qui sont \u00e9lectriquement isol\u00e9s les uns des autres. Les virages ratio d'un transformateur est le rapport du nombre de tours dans la bobine primaire, le nombre de tours dans la bobine secondaire. Il d\u00e9termine la tension de rapport de transformation entre les circuits primaires et secondaires.","breadcrumb":{"@id":"https:\/\/www.lstransformer.com\/how-to-calculate-the-turns-ratio-of-a-transformer\/#breadcrumb"},"inLanguage":"fr-FR","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.lstransformer.com\/how-to-calculate-the-turns-ratio-of-a-transformer\/"]}]},{"@type":"ImageObject","inLanguage":"fr-FR","@id":"https:\/\/www.lstransformer.com\/how-to-calculate-the-turns-ratio-of-a-transformer\/#primaryimage","url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742179274684409.png","contentUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742179274684409.png","width":370,"height":276},{"@type":"BreadcrumbList","@id":"https:\/\/www.lstransformer.com\/how-to-calculate-the-turns-ratio-of-a-transformer\/#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"\u9996\u9875","item":"https:\/\/www.lstransformer.com\/"},{"@type":"ListItem","position":2,"name":"How to Calculate the Turns Ratio of a Transformer"}]},{"@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\/1393","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=1393"}],"version-history":[{"count":5,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1393\/revisions"}],"predecessor-version":[{"id":6752,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/posts\/1393\/revisions\/6752"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/media\/2494"}],"wp:attachment":[{"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/media?parent=1393"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/categories?post=1393"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.lstransformer.com\/fr\/wp-json\/wp\/v2\/tags?post=1393"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
