AI Technical Summary
In existing amorphous alloy oil-immersed transformers, stress in the high-voltage coil during short-circuit tests causes damage to the core, resulting in excessive no-load losses and making it difficult to pass third-party testing, thus wasting human, material, and financial resources.
The design employs an internal insulation frame, insulation components, and clamping components, including high and low voltage coils, an amorphous alloy core, insulation components, and clamping components. The clamping components protect the amorphous alloy core, resist the stress of the high voltage coil during short-circuit tests, and improve the pass rate of the transformer in short-circuit tests.
It effectively protects the amorphous alloy core, improves the pass rate of transformers in short-circuit tests, reduces testing costs and risks, enhances the overall strength of the clamping assembly, and facilitates installation and disassembly.
