Daelim Transformer 3000 kVA Power Transformer

Transformer Features

The 3000 kVA power transformer features a primary voltage of three-phase 34,500V Delta and a secondary voltage of three-phase 480GrdY/277V. It employs the KNAF cooling method with a set of fans. The power rating under self-cooling is 2500 kVA, which increases to 3000 kVA when the fan is turned on. Additionally, it includes a 5-position tap changer. The high and low voltage bushings have a side-mounted design, with the HV featuring a full-height air terminal chamber (bottom entry). The LV bushing is specifically designed with a throat for easy connection to switchgear.

The utilization of aluminum winding material offers improved conductivity, reduced weight, and lower cost.

FR3 Oil

3000 kva power transformer package FR3 oil is vegetable oil, a degradable and environmentally friendly insulating oil. With a fire point greater than 300°C, and with UL certification, such insulating oil makes the transformer safer and has better insulation performance, which can increase the service life of the transformer.

Gauges

The system includes a liquid level indicator, thermometer, pressure relief device, vacuum pressure gauge, and winding temperature indicator gauges with auxiliary contacts for alarm and trip functions.

Rapid Pressure Rise Relay

A rapid pressure rise relay on the transformer provides protection in the event of a rapid increase in tank pressure. This safety component detects sudden pressure fluctuations that exceed predetermined safety limits.

Lightning Arresters

Lightning arresters on the primary side provide over-voltage and transient voltage protection against lightning, internal switching, or voltage surges. Designed to intercept and divert excessive voltage spikes away from the primary winding of the transformer, they ensure the protection and integrity of the transformer and associated components.

Valves

Complete with essential features for optimal operation, including a pressure relief valve, fill valve, drain valve equipped with a sampler port for easy fluid sampling, and a nitrogen blanket featuring a purge valve to ensure a controlled atmosphere within the transformer.

Mount

Suitable for outdoor applications.

Benefits

The transformer delivers significant energy efficiency improvements, resulting in reduced power consumption and operational expenses. Additionally, its environmentally friendly design minimizes carbon emissions, contributing to a cleaner and more sustainable energy ecosystem. These factors collectively extend the lifespan of the transformer and decrease maintenance and replacement costs over time.

Applications

The transformer finds versatile applications across various sectors, including renewable energy installations, crypto mining, energy storage facilities, electric vehicle charging stations, data centers, industrial complexes, oil and gas operations, commercial establishments, military facilities, processing plants, power distribution networks, and utility infrastructure, among others.
