I. Upgraded Core Structure, Laying a Solid Foundation for Stable Operation
The excellent performance of the S11-M series oil-immersed transformers stems from their refined structural design and high-quality material selection, with every detail designed to adapt to complex scenarios:
1. Core Design: Adopting high-quality grain-oriented cold-rolled silicon steel sheets, combined with an all-inclined hole-free binding structure, the core is overall in a multi-level stepped shape with three-joint or five-joint technology. This effectively reduces no-load loss and operating noise, improves power conversion efficiency, reduces energy waste, and adapts to the long-term stable operation needs of new energy projects.
2. Coil Configuration: Wound with high-quality QQ enameled round copper wires, flat copper wires drawn from oxygen-free copper rods, or copper bars. The coil forms include cylindrical, continuous, new spiral, split, etc., with sufficient electrical strength, mechanical strength, and heat dissipation capacity. It can withstand voltage fluctuations during new energy grid connection and avoid coil overheating or damage.
3. Oil Tank Technology: Welded with high-quality steel plates, it can be designed into elliptical, rectangular and other structures according to scene needs. The cooling elements adopt chip radiators, expansion radiators or corrugated oil tanks to ensure efficient and uniform heat dissipation. Before leaving the factory, it undergoes strict sealing tests. The inner and outer surfaces are treated with pickling and phosphating, and then sprayed with three layers of primer, which not only has excellent corrosion resistance but also has a beautiful appearance, and can adapt to harsh environments such as high humidity and high salt spray.
II. Full-Specification Technical Adaptation, Meeting the Needs of New Energy and Multi-Scenarios
The S11-M series transformers cover multiple voltage levels of 10kV, 20kV, and 35kV, with rated capacities ranging from 30kVA to 2500kVA. The complete specifications can flexibly match new energy projects and industrial scenarios of different scales, with prominent advantages in core technical parameters:
This series of products has low no-load loss, small load loss, precise control of no-load current, and stable short-circuit impedance, complying with relevant international standards. It can not only meet the power transmission needs during new energy grid connection, ensure the efficient grid connection of clean energy such as photovoltaic and wind power, but also adapt to conventional scenarios such as industrial power distribution and urban-rural power supply, realizing multi-purpose use. Whether it is a small distributed photovoltaic power station, a large wind power base, or the power distribution needs of industrial plants, the corresponding specification and model can be found.
III. Full Coverage of Multi-Scenarios, Adapting to Dual Needs of Harsh Environments and New Energy Grid Connection
With strong environmental adaptability, the S11-M series oil-immersed transformers have become core equipment for new energy grid connection and harsh environment projects, with a wide range of application scenarios:
1. New Energy Grid Connection Scenarios: It can be directly adapted to the grid connection needs of photovoltaic power stations and wind farms, stably transmit clean energy, reduce power loss, ensure the reliable operation of new energy power generation systems, and help achieve global dual-carbon goals.
2. Harsh Environment Scenarios: Particularly suitable for places with flammable, explosive and high fire protection requirements, as well as harsh environments such as drilling platforms, oil platforms, and industrial and mining enterprises. At the same time, it can be widely used in high-rise buildings, commercial centers, subways, airports, stations and other densely populated or complex working condition areas, effectively resisting the impact of environmental factors on equipment operation.
3. Conventional Power Distribution Scenarios: It can cover the conventional power distribution needs of residential areas, commercial streets, and rural power lighting, providing stable and safe power supply for various scenarios.
Relying on PEOPLE Electric’s full-industry-chain manufacturing advantages and strict quality control system, the S11-M series oil-immersed transformers, with the characteristics of low loss, high reliability, and strong adaptability, not only meet the efficient needs of new energy grid connection but also can calmly cope with the challenges of various harsh environments, providing solid support for global power construction and new energy development.
