Random sampling of Haihong 3D wound core transformers can pass the sudden short circuit test

Transformer is an important energy-consuming equipment in the power grid system, and its quality plays an important role in ensuring the safety of the power grid and reducing line losses. In recent years, the State Grid Corporation of China and China Southern Power Grid Corporation have strengthened the quality management of distribution network materials, and increased the quality supervision and sampling inspection of power transformers. From the published results of transformer quality sampling inspections, it was found that the most unqualified items in transformer quality sampling inspections were Transformer sudden short circuit test items.

Haihong Electric Co., Ltd. actively responds to the national call for energy conservation and emission reduction, adheres to scientific and technological innovation, casts high-quality goods with the spirit of craftsmanship, continuously optimizes and innovates three-dimensional wound core transformers, improves technology, strives for excellence, and continuously improves product quality and performance.

In order to further verify the anti-sudden short-circuit test capability of Haihong three-dimensional wound core transformer, recently, Haihong Electric Co., Ltd. randomly selected a number of self-developed SH15 series amorphous alloy three-dimensional wound core transformers and secondary energy efficiency S13-M from the product warehouse. .RL three-dimensional wound core transformers were sent to the National Medium and Low Voltage Power Transmission and Distribution Equipment Quality Supervision and Inspection Center for sudden short-circuit tests, all of which passed the sudden short-circuit test at one time.

The sudden short circuit test is a special test for transformers, and it is the "most stringent" comprehensive assessment of transformer structure design, manufacturing process and safe and reliable operation. A large number of professional data prove that the transformer products that have passed the sudden short circuit test generally have sufficient tolerance and stability in operation, and the product life is also longer. The randomly selected products all successfully passed the sudden short-circuit test, which verified the reliability and stability of Haihong's three-dimensional wound core transformer, reflecting the technical innovation strength of Haihong Electric. In the future, Haihong will continue to improve product performance, make continuous efforts to save energy and reduce emissions for the country, and provide users with better and better products.
