33 11 Kv 11kv 400v 1mva 1000kva 500kva 300kva 315 Kva Oil-immersed Power Distribution Transformer

Overview of 33 11 Kv 11kv 400v 1mva 1000kva 500kva 300kva 315 Kva Oil-immersed Power Distribution Transformer

An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

Features of 33 11 Kv 11kv 400v 1mva 1000kva 500kva 300kva 315 Kva Oil-immersed Power Distribution Transformer

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

This transformer takes care of power circulation successfully. It steps down high voltage electrical power to much safer, functional degrees. Typical arrangements include 33kV to 11kV, 11kV to 400V, or 11kV directly to 400V. It provides the reduced voltage required for factories, structures, and various other facilities.

Offered capacities range widely: 300kVA, 315kVA, 500kVA, 1000kVA (1MVA). This versatility suits various power needs. The core utilizes high-grade laminated steel. Windings are copper or aluminum, chosen forever conductivity and resilience. Mineral oil fills up the container. The oil protects the interior components and cools the transformer throughout operation.

The key side accepts either 33kV or 11kV input. The second side reliably outputs 400V, three-phase power. This is the standard voltage for commercial and business equipment. Performance is high, typically above 98.5% at complete lots. Losses are lessened through careful style.

Vital safety and security functions are constructed in. A Buchholz relay detects inner mistakes and gases. A stress alleviation device safeguards against dangerous overpressure. An oil degree scale shows the oil quantity. Temperature level indicators keep an eye on the oil and winding warmth.

It operates reliably within typical ambient temperatures. Sound levels are maintained low, normally under 65dB. The system undertakes rigorous screening. This includes regular tests per IEC criteria before leaving the factory. Quality checks guarantee reputable efficiency.

The transformer utilizes a conservator storage tank. This enables the oil to increase and get safely. Radiators or cooling fins help dissipate warm. The robust steel storage tank provides security. Weight varies considerably by ability, from several loads upwards. Setup options are functional: pad-mounted outdoors or placed inside your home within a suitable room. Proper grounding is compulsory for safety and feature.

Applications of 33 11 Kv 11kv 400v 1mva 1000kva 500kva 300kva 315 Kva Oil-immersed Power Distribution Transformer

These oil-immersed power distribution transformers handle essential voltage adjustments securely. They reliably step down higher voltages like 33kV or 11kV to useful 400V levels. Typical sizes include 1MVA, 1000kVA, 500kVA, 300kVA, and 315kVA. Their oil cooling down makes them durable for demanding tasks.

Manufacturing facilities depend heavily on these transformers. They power big makers, electric motors, and entire assembly line. The transformer brings grid power to the appropriate voltage for factory equipment. It ensures steady procedure critical for manufacturing.

Big structures require these devices as well. They disperse power throughout shopping center, healthcare facilities, and office facilities. The transformer receives tool voltage from the utility. It then supplies lower voltage to internal panels feeding lights, outlets, and cooling and heating systems. This arrangement is crucial for secure, reliable building power.

Renewable resource tasks utilize these transformers. Solar ranches or wind parks create power at medium voltage. The transformer actions this up a little for grid link. Conversely, it steps down grid power for on-site usage at the generation center. It’s a crucial link in green energy systems.

Construction sites commonly require momentary power. These robust, oil-filled transformers are excellent. They deal with the harsh conditions. They supply safe 400V power for tools, lights, and site workplaces from short-lived tool voltage feeds. Their durability is important right here.

Remote locations gain from these transformers. Mines, vineyards, or separated areas regularly require localized power distribution. The transformer attaches to a tool voltage line. It after that creates a reduced voltage network for the area. This brings reliable power where grid facilities is limited.

Utilities mount them within their circulation networks. They take care of voltage degrees in between substations and end clients. This makes certain power reaches homes and services effectively. The transformer is a workhorse in the power distribution chain.

5 FAQs of 33 11 Kv 11kv 400v 1mva 1000kva 500kva 300kva 315 Kva Oil-immersed Power Distribution Transformer

Here are 5 common questions about our 33kV/11kV/400V Oil-immersed Power Distribution Transformers (1MVA, 1000kVA, 500kVA, 300kVA, 315kVA):

What is this transformer for?
This transformer changes high voltage electricity (33kV or 11kV) to lower voltage (400V). It’s used to distribute power safely. Factories, large buildings, and substations rely on it. It brings power from the grid down to usable levels for equipment.

Where do I install it?
Install it outdoors. It needs a solid concrete pad. Ensure good air flow around it. Keep it away from walls or other objects. You need clearance for safety and maintenance. The site must be level and dry.

What size do I need?
Choose the size (like 500kVA or 1MVA) based on your total power demand. Add up all the equipment you need to run. Include some extra capacity for future growth. Getting the size wrong causes problems. Too small overloads it. Too big wastes money.

Why does it use oil?
The oil does two main jobs. It cools the transformer. The windings get hot during operation. The oil absorbs this heat. It also insulates the internal parts. This prevents electrical shorts. The oil tank helps dissipate the heat safely.

How long does it last?
With proper care, expect over 20 years of service. Regular maintenance is key. This includes checking oil levels, testing oil quality, and cleaning connections. Protect it from harsh weather. Follow the manufacturer’s service schedule strictly.
