Single - Phase Oil - Immersed Transformer Product Description
I. General Introduction
Our single - phase oil - immersed transformers are engineered to meet the diverse power distribution needs across various industries. These transformers are designed with the highest standards of quality and reliability in mind, utilizing advanced technologies and premium materials. They are an ideal solution for applications where efficient and stable power transformation is required.
II. Technical Features
A. Design
- Core Design: The core of our single - phase oil - immersed transformers is made of high - quality grain - oriented electrical steel. This material significantly reduces core losses, improving the overall efficiency of the transformer. The core is carefully laminated to minimize eddy current losses, ensuring long - term reliable operation.
- Winding Design: The windings are constructed with high - conductivity copper or aluminum conductors. The winding arrangement is optimized to provide excellent electrical performance and thermal stability. The use of advanced insulation materials ensures high dielectric strength and resistance to electrical breakdown.
B. Cooling System
These transformers are oil - immersed, which provides efficient cooling. The oil acts as both a coolant and an insulator. The transformer tank is designed with a large surface area to enhance heat dissipation. Additionally, optional cooling devices such as radiators or fans can be installed to further improve the cooling efficiency, especially in high - load or high - temperature environments.
C. Protection System
- Over - current Protection: Built - in over - current protection devices are used to safeguard the transformer from excessive current flow. These devices can quickly detect abnormal current conditions and take appropriate actions, such as tripping the circuit breaker, to prevent damage to the transformer.
- Over - temperature Protection: Temperature sensors are installed in the transformer to monitor the temperature of the oil and windings. When the temperature exceeds the preset limit, an alarm will be triggered, and if necessary, the transformer will be automatically shut down to prevent overheating.
III. Technical Parameters (ANSI Standards)
A. Voltage Ratings
- Primary Voltage: The primary voltage can be selected from a wide range, typically from 240V to 13,800V, depending on the specific application requirements.
- Secondary Voltage: The secondary voltage is usually 120V, 240V, or other standard values, which can be adjusted according to customer needs.
B. Power Ratings
The power ratings of our single - phase oil - immersed transformers range from 1 kVA to 500 kVA, allowing for a wide variety of power distribution applications.
C. Frequency
The transformers are designed to operate at a frequency of 60Hz, which complies with the ANSI standard for power systems in North America.
D. Impedance
The impedance of the transformer is typically in the range of 2% - 5%, which is carefully controlled to ensure proper voltage regulation and short - circuit current limitation.
E. Efficiency
Our transformers are highly efficient, with full - load efficiency typically above 95%. This high efficiency not only reduces energy consumption but also lowers operating costs over the long term.
IV. Installation and Maintenance
A. Installation
The installation of our single - phase oil - immersed transformers should be carried out by qualified electricians in accordance with the installation manual and local electrical codes. The transformer should be installed on a flat and stable foundation, and proper ventilation and clearance should be provided around the transformer.
B. Maintenance
Regular maintenance is essential to ensure the long - term reliable operation of the transformer. This includes checking the oil level, oil quality, and insulation resistance regularly. The cooling system and protection devices should also be inspected and tested periodically to ensure their proper functioning.
V. Conclusion
Our single - phase oil - immersed transformers offer a reliable, efficient, and cost - effective solution for power distribution applications. With strict compliance to ANSI standards and a commitment to quality, these transformers are sure to meet your power transformation needs.
