Si le soudage des r\u00e9parations sont effectu\u00e9es pendant une panne de courant avec de l'huile de drainage, le transformateur corps reste \u00e0 l'int\u00e9rieur du r\u00e9servoir d'huile. Comme l'isolation du transformateur corps est d\u00e9j\u00e0 impr\u00e9gn\u00e9 avec de l'huile, il y aura toujours des r\u00e9sidus d'huile et de gaz dans le r\u00e9servoir. Pendant le soudage \u00e0 l'arc des r\u00e9parations, le p\u00e9trole et le gaz sont sujettes \u00e0 la combustion en raison de la chaleur g\u00e9n\u00e9r\u00e9e par l'arc \u00e9lectrique. Si la d\u00e9cision est prise de supprimer compl\u00e8tement le transformateur pour l'huile de drainage de soudage et de r\u00e9paration, il n\u00e9cessite une quantit\u00e9 importante de travaux de d\u00e9mant\u00e8lement. En outre, le transformateur corps, si elle est expos\u00e9e \u00e0 l'air pendant une p\u00e9riode prolong\u00e9e, doit faire l'objet de re-s\u00e9chage, et l'huile d'adh\u00e9rer \u00e0 l'int\u00e9rieur du r\u00e9servoir doit \u00eatre nettoy\u00e9 par de la vapeur de rin\u00e7age avant de souder les r\u00e9parations peuvent prendre place. Il en r\u00e9sulte une charge de travail consid\u00e9rable et de panne prolong\u00e9e.<\/p>\n<p>Ainsi, les r\u00e9parations peuvent \u00eatre r\u00e9alis\u00e9es avec de l'huile pr\u00e9sente? La combustion de p\u00e9trole n\u00e9cessite certaines conditions, \u00e0 savoir une temp\u00e9rature sp\u00e9cifique et \u00e0 un approvisionnement suffisant en oxyg\u00e8ne. Lors de la r\u00e9alisation des r\u00e9parations avec de l'huile pr\u00e9sente, m\u00eame si une quantit\u00e9 importante de chaleur est transf\u00e9r\u00e9e \u00e0 l'huile \u00e0 travers les parois du r\u00e9servoir, l'huile subit convection dissipation de la chaleur, provoquant la temp\u00e9rature \u00e9lev\u00e9e de l'huile perd rapidement de la chaleur. Au moment de la soudure, de la temp\u00e9rature imm\u00e9diatement adjacentes \u00e0 la zone de soudage \u00e0 l'int\u00e9rieur du r\u00e9servoir est que d'environ 55\u00b0C, et la dur\u00e9e de la soudure avec de l'huile est de courte dur\u00e9e, emp\u00eacher l'huile de s'enflammer. En outre, il n'y a pas d'air \u00e0 l'int\u00e9rieur du r\u00e9servoir d'huile, et l'huile elle-m\u00eame manque d'oxyg\u00e8ne. Donc, avec un bon contr\u00f4le, r\u00e9parations de soudure avec de l'huile pr\u00e9sente ne sera pas conduire \u00e0 la combustion.<\/p>\n<p>Cependant, pendant le processus de r\u00e9paration, l'huile qui a d\u00e9j\u00e0 coul\u00e9 et est actuellement en fuite ne peut pas facilement la combustion, mais il est tr\u00e8s sujettes \u00e0 la combustion et la d\u00e9composition, g\u00e9n\u00e9rant un puissant flux d'air qui le rend difficile pour que les gouttelettes d'atteindre le point de fuite. L'huile Excessive de flux peut m\u00eame \u00e9teindre l'arc \u00e9lectrique directement, le rendu de la r\u00e9paration impossible \u2013 un d\u00e9fi important dans le soudage de r\u00e9paration. En outre, la combustion des vapeurs de p\u00e9trole m\u00e9lang\u00e9 avec de l'huile p\u00e9n\u00e8tre dans le point de fuite. M\u00eame si des gouttelettes g\u00e9rer pour atteindre le point de fuite par la rupture par le biais de la circulation de l'air, ils peuvent avoir des difficult\u00e9s \u00e0 fusionner de mani\u00e8re efficace avec le m\u00e9tal au point de fuite, un impact sur la densit\u00e9 de la soudure et de multiples fuites. Enfin, l'intensit\u00e9 de la convection transfert de chaleur dans le r\u00e9servoir d'huile emp\u00eache la temp\u00e9rature des parois de la cuve de la mont\u00e9e, provoquant la fuite de p\u00e9trole \u00e0 se d\u00e9composer rapidement et les gouttelettes de refroidir rapidement, r\u00e9duisant leur capacit\u00e9 de fusion.<\/p>\n<h2 style=\"font-weight: bold;\">Contact<\/h2>\n<p>LuShan, heure de l'est. 1975, est un fabricant professionnel Chinois sp\u00e9cialis\u00e9 dans les transformateurs de puissance et des r\u00e9acteurs de plus de 50 ans.

If the decision is made to completely dismantle the transformer for oil drainage and welding repairs, it entails a significant amount of dismantling work. Additionally, the transformer body, if exposed to the air for an extended period, needs to undergo re-drying, and the oil adhering to the inside of the tank must be cleaned through vapor flushing before welding repairs can take place. This results in substantial workload and prolonged power outage.","og_url":"https:\/\/www.lstransformer.com\/fr\/can-transformers-be-welded-with-oil-for-repair\/","og_site_name":"LS power transformer, Line reactor, High-voltage transformer, Oil-immersed transformer-CHANGSHA LUSHAN ELECTRONIC TECHNOLOGY CO.,LTD","article_published_time":"2026-07-22T05:33:30+00:00","article_modified_time":"2026-09-26T16:27:23+00:00","og_image":[{"width":370,"height":276,"url":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742009530677603.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\/can-transformers-be-welded-with-oil-for-repair\/#article","isPartOf":{"@id":"https:\/\/www.lstransformer.com\/can-transformers-be-welded-with-oil-for-repair\/"},"author":{"name":"369703005","@id":"https:\/\/www.lstransformer.com\/#\/schema\/person\/674089c15f4857c19a997f886816d289"},"headline":"Can transformers be welded with oil for repair?","datePublished":"2026-07-22T05:33:30+00:00","dateModified":"2026-09-26T16:27:23+00:00","mainEntityOfPage":{"@id":"https:\/\/www.lstransformer.com\/can-transformers-be-welded-with-oil-for-repair\/"},"wordCount":568,"publisher":{"@id":"https:\/\/www.lstransformer.com\/#organization"},"image":{"@id":"https:\/\/www.lstransformer.com\/can-transformers-be-welded-with-oil-for-repair\/#primaryimage"},"thumbnailUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742009530677603.png","articleSection":["FAQ"],"inLanguage":"fr-FR"},{"@type":"WebPage","@id":"https:\/\/www.lstransformer.com\/can-transformers-be-welded-with-oil-for-repair\/","url":"https:\/\/www.lstransformer.com\/can-transformers-be-welded-with-oil-for-repair\/","name":"Peut transformateurs \u00eatre soud\u00e9 avec de l'huile pour la r\u00e9paration? - 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\/can-transformers-be-welded-with-oil-for-repair\/#primaryimage"},"image":{"@id":"https:\/\/www.lstransformer.com\/can-transformers-be-welded-with-oil-for-repair\/#primaryimage"},"thumbnailUrl":"https:\/\/www.lstransformer.com\/wp-content\/uploads\/2026\/07\/1742009530677603.png","datePublished":"2026-07-22T05:33:30+00:00","dateModified":"2026-09-26T16:27:23+00:00","description":"La r\u00e9paration de fuite d'huile dans le transformateur de soudage lignes est une t\u00e2che cruciale pour le personnel d'exploitation.
