Overview of Three-phase Oil-immersed Power Transformer, 11kv, 6kv, 160kva, 250kva, 315kva, Current Transformer, High-frequency Transformer

Un trasformatore immerso in olio è un tipo di trasformatore elettrico in cui il nucleo e gli avvolgimenti sono immersi in un olio isolante. Questo olio svolge due funzioni principali: agisce come un isolante altamente efficace tra le parti conduttrici e come refrigerante per dissipare il calore generato durante il funzionamento. Questi trasformatori sono robusti, affidabile, e altamente efficiente, rendendoli la scelta standard per le reti di distribuzione e trasmissione di energia ad alta tensione, tipicamente installato all'aperto nelle sottostazioni.

Features of Three-phase Oil-immersed Power Transformer, 11kv, 6kv, 160kva, 250kva, 315kva, Current Transformer, High-frequency Transformer

• Raffreddamento efficace: L'olio isolante assorbe efficacemente il calore dal nucleo e dagli avvolgimenti e lo trasferisce alle alette del radiatore, consentendo la circolazione naturale o forzata e una maggiore capacità di sovraccarico.
• Isolamento superiore: L'olio fornisce una rigidità dielettrica molto migliore rispetto all'aria, consentendo un design più compatto per una determinata tensione nominale e proteggendo dai cortocircuiti.
• Costruzione robusta: Progettato per il lungo termine, funzionamento affidabile (Spesso 25-30 anni) in ambienti esterni difficili.
• Capacità di sovraccarico: Può gestire sovraccarichi di potenza temporanei meglio dei trasformatori di tipo a secco grazie alla massa termica e alle proprietà di raffreddamento dell'olio.
• Sistema di protezione: Dotato di serbatoio conservatore (per consentire l'espansione dell'olio), respiro (per assorbire l'umidità dall'aria), e relè di protezione (Staffetta Buchholz) per il rilevamento dei guasti interni.
• Conveniente: Generalmente più economico per applicazioni ad alta potenza rispetto ai trasformatori a secco.

The entire device is built hard inside a steel storage tank. This protects it from climate and harsh conditions.

Setup is uncomplicated. It requires a strong, degree base. Proper grounding is necessary for safety and security. Regular checks on the oil degree and condition are necessary. Upkeep is typically easy. The design concentrates on lengthy service life. These transformers fulfill tough safety and security rules. They have defense versus overloads and brief circuits. This makes them trustworthy for continuous operation.

We likewise supply present transformers (CTs). 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, Current Transformer, High-frequency Transformer

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, manageable level. 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, not iron. 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, Current Transformer, High-frequency Transformer

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

What jobs do these transformers handle?
Our oil-immersed power transformers manage power distribution in factories, buildings, and substations. 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.

How do I pick the right size (kva)?
Choosing the correct kva rating is vital. First, 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.

Are these transformers safe?
Safety is built in. 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.

What maintenance is needed?
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.
