How to improve the anti-corrosion application of oil immersed transformers in powerSinopower Transformer (Changzhou) Co. Ltd. Oil-Immersed Transformer To reduce heating losses and minimize size and weight, the core is built from high-permeability cold-rolled grain-oriented silicon-steel sheets thinner than 0.35 mm. This allows the heat generated by core losses to be fully carried away by the circulating insulating oil, ensuring excellent cooling performance. Oil-Immersed TransformerWhen subjected to short-circuit currents, large electromagnetic forces are produced in the windings, which can damage the transformer. An inter-turn short circuit may occur even if part of the winding is above the oil level. Additionally, during through-fault conditions, the overcurrent can deform the windings, causing mechanical damage to the insulation and resulting in inter-turn faults.2025-11-20

What are the excellent reputations of oil immersed transformers for problem transformationSinopower Transformer (Changzhou) Co. Ltd, Ltd.'s oil immersed transformers are usually double winding transformers, which have two windings on the iron core, one is the primary winding and the other is the secondary winding. They are composed of the iron core, winding, oil tank, oil pillow, insulation sleeve, tap changer, and gas relay.When an oil immersed transformer is subjected to short-circuit current, a large electromagnetic force will be generated on the winding, causing damage to the transformer. The basic windings have two types: concentric and overlapping. Vacuum oil filtration and oil injection processes are used to minimize the moisture inside the transformer. A non suspended structure is adopted, which can withstand transportation vibrations.2025-11-20

What are the protection methods for creating high-quality dry-type transformersSinopower Transformer (Changzhou) Co. Ltd'sdry-type transformer adopts advanced domestic technology, with high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life. It adopts an intelligent signal temperature control system, which can automatically detect and display the working temperature of each three-phase winding, automatically start and stop the fan, and has functions such as alarm and trip settings.Dry type transformers use high-quality cold-rolled grain oriented silicon steel sheets, and the iron core silicon steel sheets use 45 degree fully oblique joints to allow magnetic flux to pass along the direction of the silicon steel sheet joints. In key projects and major engineering projects in China, it is difficult to find traces of foreign dry type transformers2025-11-20

How to ensure that the monitoring environment of the box type transformer is not affectedSinopower Transformer (Changzhou) Co. Ltd's box type transformer is fully sealed, fully insulated, compact in structure, aesthetically pleasing in appearance, and only about one-third the size of a box type substation (European box type transformer). Disconnect the circuit breaker on the high-voltage side of the maintenance transformer, close the grounding switch, fully discharge the transformer, lock the high-voltage cabinet, and hang a "Do Not Close" sign at the switch handle.Clean the dust around and on the accessories of the box type transformer, check whether the fire-fighting facilities and ventilation system are in good condition, use aluminum zinc coated steel plates, and use standard container materials and manufacturing processes for the frame.2025-11-20

New energy generation and energy storage solutionsDue to the characteristics of new energy sources such as photovoltaics and wind power, the quality of power generation is unstable, and the problem of abandoned wind and solar power is prominent, seriously restricting the rapid development of new energy. Configuring energy storage systems can effectively solve these problems. The country requires new energy projects to be connected to the grid with mandatory energy storage, which effectively improves the development of new energy and lays a solid foundation for achieving the dual carbon goals as soon as possible.2025-11-20

Application principle of bidirectional energy storage transformerThe product is used in energy storage systems by connecting with energy storage components to the public grid. During periods of low grid load, it converts AC energy from the grid into DC energy to charge the energy storage components. During periods of high grid load, it converts the DC energy from the energy storage components into AC energy that meets the requirements of the grid and feeds it back to the public grid, playing a role in peak shaving and valley filling.2025-11-20
