3 Three Phase 315 KVA 330kVA 350 KVA Hv Lv Oil Immersed Power Distribution Transformer

Overview of 3 Three Phase 315 KVA 330kVA 350 KVA Hv Lv 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 3 Three Phase 315 KVA 330kVA 350 KVA Hv Lv 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.

Specifications of 3 Three Phase 315 KVA 330kVA 350 KVA Hv Lv Oil Immersed Power Distribution Transformer

Here are the specifications for 3 oil-immersed power distribution transformers: 315 kVA, 330 kVA, そして 350 kVA. These are three-phase units made for stepping down high voltage to reduced voltage. They are built for dependable power distribution.

The main high voltage rating is generally 11,000 volts or 33,000 volts. The secondary reduced voltage is typically 400 volts. Certain voltage combinations are readily available to satisfy project needs. These transformers utilize mineral oil for insulation and cooling. The oil flows normally around the core and windings. This ONAN cooling technique is typical and effective.

The core is made from high-grade, grain-oriented silicon steel. This minimizes energy losses during operation. The windings are copper permanently conductivity and efficiency. They are meticulously prepared on the core. The entire energetic component sits inside a robust welded steel container. This tank holds the shielding oil. The container is sealed to keep wetness out.

Operating temperature restrictions are important. The typical winding temperature increase must not surpass 65 ° C. The top oil temperature level increase need to not surpass 55 ° C. These restrictions are determined above the ambient air temperature. The ambient temperature level is typically a maximum of 40 ° C. The transformers satisfy standard efficiency levels. They follow IEC 60076 or comparable international requirements. Losses are kept low: no-load losses and tons losses are enhanced.

The transformers consist of crucial devices. There is an oil degree indicator on the container. A pressure relief tool shields versus interior over-pressure. A drain shutoff enables oil tasting or draining pipes. An earthing terminal is attended to safety and security. Raising lugs are fitted for risk-free handling throughout installment. These units are made for long life span. They handle requiring distribution atmospheres well.

Applications of 3 Three Phase 315 KVA 330kVA 350 KVA Hv Lv Oil Immersed Power Distribution Transformer

These power transformers manage significant electrical energy requirements. They step down high voltage to safer, useful reduced voltage. This happens successfully inside their oil-filled storage tanks. The oil cools every little thing and stops electrical troubles.

Manufacturing facilities utilize these transformers daily. Large devices need trusted power. A 350kVA unit commonly feeds whole assembly line or big electric motor control centers. It maintains points running without voltage drops. Storehouses depend upon them as well. Lights, conveyor belts, and packaging devices run smoothly.

Shopping mall and office buildings require them. These places utilize great deals of power for lights, air conditioning, and computers. A 315kVA or 330kVA transformer may power a whole area of a mall or a multi-story workplace block. It guarantees stores stay open and workplaces function right.

Building websites utilize them temporarily. Large jobs need momentary high-capacity power prior to the long-term grid connects. These transformers supply it safely. They power cranes, cement mixers, and website offices up until the work finishes.

Water treatment plants count on them. Pumps and filtration systems run regularly. A 350kVA transformer provides the stable power these crucial facilities demand. Farms with big irrigation systems also use them. Big pumps moving water need robust power shipment.

These transformers are workhorses. They are constructed difficult for years of service. The oil insulation allows them to manage heavy tons consistently. They sit quietly in substations or on pads outside buildings. You discover them where considerable, trusted power distribution is non-negotiable. They create a crucial web link between the high-voltage grid and the equipment individuals actually make use of.

5 FAQs of 3 Three Phase 315 KVA 330kVA 350 KVA Hv Lv Oil Immersed Power Distribution Transformer

What are these 315-350kVA oil transformers for?
These transformers take high voltage electricity from the grid. They step it down to safer, usable low voltage levels. Factories, large buildings, hospitals, and industrial sites use them for their main power distribution. They handle the heavy electrical loads these places need.

How does the oil cooling work?
The transformer core and windings sit inside a strong steel tank filled with special insulating oil. This oil does two big jobs. It stops electrical arcs inside the transformer. It also pulls heat away from the core and windings. The heat moves to the oil. The oil then carries the heat to the tank walls. The tank walls release the heat into the surrounding air. Bigger models might have extra cooling tubes or radiators for more surface area.

What voltages can these transformers handle?
You can order them with different high voltage and low voltage combinations. Common HV inputs are 11kV, 22kV, or 33kV. Common LV outputs are 400V, 415V, or 480V. Tell us your specific incoming voltage and required output voltage. We build the transformer to match your exact site needs.

Are these transformers safe?
はい, safety is built in. They follow strict international standards like IEC. The tank is very strong. It holds the oil securely. Good models have pressure relief devices. These vent safely if internal pressure gets too high. Temperature gauges monitor oil heat levels. They also have overload protection. This helps prevent damage if demand spikes unexpectedly.

What about installing one?
You need enough space. The site must be flat, 安定した, and dry. Remember the transformer is heavy when full of oil. You need space around it for air to flow freely. This keeps cooling working right. You also need space for technicians to check oil levels, connections, and do maintenance safely.
