Recently, CEEG successfully exported its meticulously crafted new product, the HKSSPZ-13000/15 series voltage-regulating special transformer, to France. This further expands our market presence in France and adds a significant achievement to the company's export performance history.
In terms of technological innovation, the HKSSPZ-13000/15 series voltage-regulating special transformer adopts several new technologies:
1. Through the innovative design of using a combination of high-voltage side fine-tuning and coarse-tuning windings to supply power to the series excitation winding, the main transformer achieves constant magnetic flux while the series transformer achieves variable magnetic flux. This results in a low-voltage side current of up to 16000A and a low-voltage output ranging from 532V to 100V with 63 different levels.
2. The transformer employs a dual-body series voltage-regulating structure with an "8"-shaped low-voltage coil. Special coil winding molds and lifting tools are used, perfectly solving the winding and assembly challenges.
3. By conducting temperature field and leakage magnetic field simulation analysis and prototype testing, we have resolved the issues of local overheating during long-term overload operation at 130% and the imbalance of three-phase current on the low-voltage side exceeding 40%, ensuring the long-term stable operation of the transformer.
4. The use of a same-phase reverse parallel structure and special corner sealing measures on the low-voltage side significantly reduces eddy current losses caused by high currents on the low-voltage side.
5. The transformer is equipped with the ETOS ED intelligent control cabinet from Germany's MR company. This cabinet features an embedded automatic voltage regulator and transformer management system, enabling remote digital monitoring, control, and adjustment of the transformer. This improves operational efficiency and reduces maintenance costs, bringing higher economic benefits to users.
Our company's innovative achievements in special transformers demonstrate our technical strength and deep understanding of market demands, providing efficient and reliable power solutions to help customers improve efficiency.
