Overview of Three-phase Oil-immersed Power Transformer, 11kv, 6kv, 160kva, 250kva, 315kva, Transformateur de courant, Transformateur haute fréquence

Un transformateur immergé dans l'huile est un type de transformateur électrique dont le noyau et les enroulements sont immergés dans une huile isolante.. Cette huile remplit deux fonctions principales: il agit comme un isolant très efficace entre les pièces conductrices et comme un liquide de refroidissement pour dissiper la chaleur générée pendant le fonctionnement. Ces transformateurs sont robustes, fiable, et très efficace, ce qui en fait le choix standard pour les réseaux de distribution et de transmission d'énergie haute tension, généralement installé à l'extérieur dans les sous-stations.

• Refroidissement efficace: L'huile isolante absorbe efficacement la chaleur du noyau et des enroulements et la transfère aux ailettes du radiateur., permettant une circulation naturelle ou forcée et une capacité de surcharge plus élevée.
• Isolation supérieure: L'huile offre une bien meilleure rigidité diélectrique que l'air, permettant une conception plus compacte pour une tension nominale donnée et protégeant contre les courts-circuits.
• Construction robuste: Conçu pour le long terme, fonctionnement fiable (souvent 25-30 années) dans des environnements extérieurs difficiles.
• Capacité de surcharge: Peut mieux gérer les surcharges de puissance temporaires que les transformateurs de type sec en raison de la masse thermique et des propriétés de refroidissement de l'huile.
• Système de protection: Equipé d'un réservoir conservateur (pour permettre l'expansion du pétrole), reniflard (pour absorber l'humidité de l'air), et relais de protection (Relais Buchholz) pour la détection de défauts internes.
• Rentable: Généralement plus économique pour les applications haute puissance que les transformateurs de type sec.

We likewise supply present transformers (CT). CTs determine high currents safely. They tip down the current for meters and defense devices. CTs are important for accurate monitoring and control. They can be found in numerous proportions and precision courses. CTs function well with our power transformers.

High-frequency transformers are different. They operate at much faster changing speeds. These are except common power distribution. High-frequency types are for specialized electronics. Examples include switch-mode power supplies and inverters. They handle quick modifications in voltage and present. Their style makes use of unique materials for core loss decrease. Size is typically much smaller sized than power frequency units.

Applications of Three-phase Oil-immersed Power Transformer, 11kv, 6kv, 160kva, 250kva, 315kva, Transformateur de courant, Transformateur haute fréquence

Power transformers take care of electricity safely and effectively. Three-phase oil-immersed kinds are common for sturdy jobs. They utilize oil to protect and keep one’s cool. You discover them tipping voltage up or down. Usual voltages are 11kV and 6kV. Sizes like 160kVA, 250kVA, and 315kVA fit many demands. Manufacturing facilities utilize these transformers. Mines utilize them too. They power huge motors and machinery accurately. Substations rely upon them for local power circulation. They manage constant high lots well. The oil cooling makes them durable for challenging atmospheres. These transformers create the foundation of industrial power grids.

Present transformers, or CTs, are different. They do not change voltage much. Their task is measuring present safely. They step down high existing to a reduced, niveau gérable. Meters utilize this low signal. Protective relays use it also. You install CTs around a major power line. They let tools monitor flow without straight high-current call. This is vital for safety and security and control. Every power system needs CTs for accurate tracking and defense.

High-frequency transformers run in different ways. They work with fast-changing currents, not the typical 50Hz or 60Hz grid power. Electronics use them for changing power products. These supplies convert power efficiently. You find them in computers. Telecom tools uses them. Industrial inverters need them. Clinical devices use high-frequency transformers. Their layout uses unique cores, frequently ferrite, pas de fer. This minimizes energy loss at high frequencies. They are smaller than power transformers for the very same power level. Their function is allowing compact, efficient power conversion in modern electronic systems.

5 FAQs of Three-phase Oil-immersed Power Transformer, 11kv, 6kv, 160kva, 250kva, 315kva, Transformateur de courant, Transformateur haute fréquence

Here are key questions customers ask about our three-phase oil-immersed power transformers (11kV, 6kV, 160kva, 250kva, 315kva), transformateurs de courant, and high-frequency transformers:

What jobs do these transformers handle?
Our oil-immersed power transformers manage power distribution in factories, bâtiments, et sous-stations. They step down higher voltages like 11kV or 6kV to usable levels. Current transformers accurately measure large electrical currents safely. High-frequency transformers work in specialized equipment needing fast switching, like certain power supplies or converters.

Comment choisir la bonne taille (kva)?
Choosing the correct kva rating is vital. D'abord, calculate your total connected load. Consider future expansion needs. Factor in the starting currents of large motors. Our 160kva, 250kva, and 315kva models cover common industrial needs. Undersizing causes overheating. Oversizing wastes money and efficiency. We help you select the perfect match.

Ces transformateurs sont-ils sûrs?
La sécurité est intégrée. The oil insulation cools the core and windings effectively. It also suppresses internal arcs. Robust steel tanks protect the internal parts. Reliable bushings prevent oil leaks at connection points. Key safety devices like the Buchholz relay detect internal gas buildup from faults. Pressure relief valves vent excess pressure safely.

Quel entretien est nécessaire?
Regular checks keep them reliable. Monitor the oil level in the sight gauge frequently. Inspect for any oil leaks around gaskets and valves. Periodically test the oil’s insulation strength and check for moisture or contaminants. We test oil samples. Listen for unusual humming or vibrations indicating loose parts. Schedule professional inspections annually.
