Product Description:
Medium and high voltage transformers that are immersed in oil play a crucial role in power systems by facilitating voltage transformation. These transformers are commonly utilized to step up or step down voltage levels, ensuring efficient power distribution across the network.
The key feature of these transformers is their use of insulating oil, which serves dual purposes. Firstly, the oil provides effective cooling by dissipating heat generated during operation. Secondly, it acts as an insulating material, enhancing the electrical insulation between the internal components.
This combination of oil cooling and insulation allows the transformers to operate reliably and maintain stability even when subjected to heavy electrical loads. As a result, oil-immersed transformers are a preferred choice in medium and high voltage applications within the power industry.
Features:
Medium and high voltage oil-immersed transformers offer numerous advantages that make them a preferred choice in various electrical applications. One of their key benefits is their high reliability and stability, which is attributed to their excellent insulation properties and strong resistance to short circuits.
Another important advantage is their efficient cooling system. The use of oil, known for its superior heat dissipation capabilities, helps in effectively reducing energy loss during operation. This efficient thermal management ensures the transformer operates safely and prolongs its service life.
Oil also provides robust insulation performance due to its high dielectric strength. This characteristic plays a crucial role in preventing arc breakdown within the transformer, thereby enhancing its operational safety and durability.
From a cost perspective, oil-immersed transformers remain economical. Despite some environmental concerns, mineral oil continues to be widely used because it offers a cost-effective solution without compromising performance.
Additionally, these transformers feature a compact design with attributes such as axial symmetry and dual high-voltage output. These design elements contribute to easier portability and flexible installation options.
Overall, these advantages make medium and high voltage oil-immersed transformers ideal for applications in power transmission, substations, and equipment testing scenarios.
Technical Parameters:
The transformer has a capacity of up to 120 MVA, making it suitable for a wide range of high-power applications. It operates with voltage levels ranging from 33 kV to 110 kV on the primary side, while the secondary side supports voltages between 10 kV and 69 kV.
The pressure regulating gear and short circuit impedance can be customized according to specific requirements, allowing for flexibility in various operational environments. This customization ensures optimal performance tailored to the needs of different projects.
For cooling, the transformer employs an oil-immersed air-cooled method (ONAF), which effectively manages heat dissipation. The temperature rise limit is controlled to maintain the top oil temperature at or below 95°C, assuming an ambient temperature of 40°C.
In terms of standards, the transformer complies with the operating regulations for oil-immersed transformers as outlined in GB 1094.1-2013. This adherence guarantees reliable quality and safety during operation.
Typically, this transformer is used in distribution scenarios where voltage needs to be stepped down from 110 kV substations to 35 kV, making it ideal for such distribution network applications.
Applications:
The TNNPI Oil Immersed Power Transformer, model number SZ, is a highly reliable and efficient Electrical Power Transformer designed to meet the demanding needs of modern power distribution systems. Originating from Zhengzhou, this three-phase Electric Power Transformer is certified with CE and ISO standards, ensuring superior quality and safety compliance. Its robust design, featuring three copper windings and mineral oil (NON-PCB) as insulating liquid, makes it an ideal solution for a wide range of outdoor power applications.
This Electrical Power Transformer is perfectly suited for installation in various outdoor service conditions where ambient temperature typically reaches around 28℃. Its durable construction ensures stable performance and longevity even in harsh environmental conditions. The oil-immersed design provides excellent insulation and cooling capabilities, making it an excellent choice for electrical power transmission and distribution networks.
