Comment R\u00e9duire Sans Pertes de Charge dans les Transformateurs?<\/h1>\n

Pas de pertes de charge dans les transformateurs reportez-vous \u00e0 la puissance consomm\u00e9e lorsque le transformateur’s enroulement secondaire est ouvert (c'est \u00e0 dire, pas connect\u00e9 \u00e0 une charge). Ces pertes comprennent principalement les pertes fer et les pertes magn\u00e9tiques. Pas de pertes de charge sont inh\u00e9rentes \u00e0 l'transformateur’s de fonctionnement et d'avoir un certain impact sur la stabilit\u00e9 \u00e0 la fois le r\u00e9seau \u00e9lectrique et le transformateur lui-m\u00eame. Les sections suivantes vont mettre en place des m\u00e9thodes pour r\u00e9duire ces pertes de charge.<\/p>\n

Contenu<\/strong><\/h2>\n

1. Transformateur de mati\u00e8res<\/em><\/b><\/h3>\n
(1) R\u00e9duire la Densit\u00e9 du Flux Magn\u00e9tique du Noyau de Transformateur<\/strong><\/h6>\n

Pas de pertes de charge sont proportionnelles au carr\u00e9 (ou 1.2 puissance) de la densit\u00e9 de flux magn\u00e9tique du noyau. Par cons\u00e9quent, une trop grande densit\u00e9 de flux magn\u00e9tique va augmenter les pertes. Dans les transformateurs \u00e0 sec, il est g\u00e9n\u00e9ralement recommand\u00e9 de conserver la densit\u00e9 du flux magn\u00e9tique du noyau en dessous de 1,60 T. Cela permet de r\u00e9duire efficacement les pertes, d'am\u00e9liorer l'efficacit\u00e9 et la fiabilit\u00e9 du transformateur. Le contr\u00f4le de la densit\u00e9 du flux magn\u00e9tique \u00e0 l'int\u00e9rieur d'un \u00e9ventail appropri\u00e9 est un facteur cl\u00e9 lors de transformateur de conception pour assurer la performance et la dur\u00e9e de vie du transformateur.<\/p>\n

(2) S\u00e9lectionnez Haute Qualit\u00e9 de Silicium de t\u00f4les d'Acier pour le Core<\/strong><\/h6>\n

Les transformateurs \u00e0 sec doivent g\u00e9n\u00e9ralement utiliser lamin\u00e9s \u00e0 froid \u00e0 haute perm\u00e9abilit\u00e9 \u00e0 grains orient\u00e9s en acier de silicium feuilles, qui ont une faible unit\u00e9 de la perte du fer, g\u00e9n\u00e9ralement n\u00e9cessaires pour \u00eatre en dessous de 1,3 W\/kg (\u00e0 1,7 T). La r\u00e9duction de l'\u00e9paisseur de la base des feuilles est \u00e9galement crucial, car les pertes par courants de foucault dans le c\u0153ur est proportionnelle au carr\u00e9 de l'\u00e9paisseur de la feuille. Par cons\u00e9quent, la base des feuilles ne doit pas \u00eatre trop \u00e9paisse. L'\u00e9paisseur de la base des feuilles dans les transformateurs \u00e0 sec est g\u00e9n\u00e9ralement de 0,3 mm, 0,27 mm, ou 0,23 mm.<\/p>\n

2. Transformateur de processus de fabrication<\/em><\/b><\/h3>\n
(1) D'Optimiser La Base Des Processus De Fabrication<\/strong><\/h6>\n

Depuis noyaux des transformateurs utilisent g\u00e9n\u00e9ralement lamin\u00e9 \u00e0 froid les t\u00f4les d'acier au silicium, qui sont anisotropes, la perm\u00e9abilit\u00e9 magn\u00e9tique est le plus \u00e9lev\u00e9 et les pertes sont minimes lorsque le flux magn\u00e9tique circule le long du sens de laminage de l'acier au silicium dans les feuilles. Lorsque le flux flux perpendiculaire au sens de laminage, les propri\u00e9t\u00e9s magn\u00e9tiques de se d\u00e9t\u00e9riorer de mani\u00e8re significative. Par cons\u00e9quent, l'aimantation de direction doivent \u00eatre consid\u00e9r\u00e9s lors de la conception et de la fabrication de la base. G\u00e9n\u00e9ralement, \u00e0 45\u00b0 onglet mixte est utilis\u00e9 pour r\u00e9duire l'angle entre le flux magn\u00e9tique et le sens de laminage de l'acier au silicium dans les feuilles, aider \u00e0 r\u00e9duire les pertes. La performance de l'acier au silicium feuilles est \u00e9galement affect\u00e9e par des contraintes externes au c\u0153ur de la transformation, alors avanc\u00e9e de l'outillage doit \u00eatre utilis\u00e9 pour minimiser les effets d\u00e9favorables sur le silicium des feuilles d'acier.<\/p>\n

(2) Utiliser Pleinement Onglet Conjointe des Structures de Base de la Conception<\/strong><\/h6>\n

Pour les transformateurs de m\u00eames caract\u00e9ristiques, l'adoption d'un enti\u00e8rement onglet structure commune peut r\u00e9duire les pertes \u00e0 vide de 5% \u00e0 6% par rapport \u00e0 l'utilisation d'un droit \u00e0 clin. Par cons\u00e9quent, enti\u00e8rement onglet de structures communes devrait \u00eatre une priorit\u00e9 dans le noyau de s\u00e9lection et de conception pour s'assurer que le transformateur fonctionne plus l'\u00e9nergie de mani\u00e8re efficace.<\/p>\n

En R\u00e9sum\u00e9<\/span><\/b><\/h2>\n

Par contr\u00f4ler efficacement sans pertes de charge, nous pouvons am\u00e9liorer l'efficacit\u00e9 du fonctionnement de transformateurs, de r\u00e9aliser des \u00e9conomies d'\u00e9nergie et des r\u00e9ductions d'\u00e9missions, et de promouvoir un d\u00e9veloppement \u00e9nerg\u00e9tique durable.<\/p>\n

The following sections will introduce methods to reduce these no-load losses.","og_url":"https:\/\/www.lstransformer.com\/fr\/how-to-reduce-no-load-losses-in-transformers\/","og_site_name":"LS power transformer, Line reactor, High-voltage transformer, Oil-immersed transformer-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","article_published_time":"2026-07-22T05:33:25+00:00","article_modified_time":"2026-09-27T06:29:19+00:00","og_image":[{"width":370,"height":276,"url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1741672391863677.png","type":"image\/png"}],"author":"369703005","twitter_card":"summary_large_image","twitter_misc":{"\u00c9crit par":"369703005","Dur\u00e9e de lecture estim\u00e9e":"4 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/#article","isPartOf":{"@id":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/"},"author":{"name":"369703005","@id":"https:\/\/www.lstransformer.com\/#\/schema\/person\/674089c15f4857c19a997f886816d289"},"headline":"How to Reduce No-Load Losses in Transformers?","datePublished":"2026-07-22T05:33:25+00:00","dateModified":"2026-09-27T06:29:19+00:00","mainEntityOfPage":{"@id":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/"},"wordCount":599,"publisher":{"@id":"https:\/\/www.lstransformer.com\/#organization"},"image":{"@id":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/#primaryimage"},"thumbnailUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1741672391863677.png","articleSection":["FAQ"],"inLanguage":"fr-FR"},{"@type":"WebPage","@id":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/","url":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/","name":"Comment R\u00e9duire Sans Pertes de Charge dans les Transformateurs? - LS transformateur de puissance, r\u00e9acteur de Ligne \u00e0 Haute tension transformateur d'Huile de transformateur immerg\u00e9-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","isPartOf":{"@id":"https:\/\/www.lstransformer.com\/#website"},"primaryImageOfPage":{"@id":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/#primaryimage"},"image":{"@id":"https:\/\/www.lstransformer.com\/how-to-reduce-no-load-losses-in-transformers\/#primaryimage"},"thumbnailUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1741672391863677.png","datePublished":"2026-07-22T05:33:25+00:00","dateModified":"2026-09-27T06:29:19+00:00","description":"Pas de pertes de charge dans les transformateurs reportez-vous \u00e0 la puissance consomm\u00e9e lorsque le transformateur de enroulement secondaire est ouvert (c'est \u00e0 dire, pas connect\u00e9 \u00e0 une charge).
