The application discloses a transformer for extra-high voltage direct current transmission engineering and relates to the technical field of transformers, in particular to a transformer for extra-high voltage direct current transmission engineering. The transformer comprises a transformer body, an oil tank arranged in the transformer body, a drain valve pipe communicated with the oil tank and mounted on one side of the transformer body, a main flow guide pipe connected with one end of the drain valve pipe, and a drain valve component and a sampling mechanism arranged at two ends of the main flow guide pipe. The transformer for extra-high voltage direct current transmission engineering is provided with the sampling mechanism. When sampling, the sampling pipe body is automatically moved up to the main flow guide pipe in an arc-shaped notch opened by itself and covered by a composite sealing ring under the transmission of the lifting transmission assembly, and then the clean oil sample in the main flow guide pipe enters the inside of the sampling pipe body along the cylinder wall of the sampling pipe body in a wall layer flow, so that air is avoided from being sucked by free jet flow. In the oil inlet process, the oil pressure pushes the piston rod in the buffer assembly to move down synchronously, and the gas in the sampling pipe body is discharged through the associated second electromagnetic valve pipe, so that the detection requirement of low-bubble sampling is met.

This invention belongs to the field of environmentally friendly fuel technology, specifically relating to a method for preparing a green, low-carbon, and highly efficient modified fuel for alcohol-hydrogen engines. This invention comprehensively improves fuel performance through a progressive synergistic architecture of a bio-methanol platform – an oxygen-containing combustion-promoting system – a stability barrier – and a low-energy-consumption blending path. Using bio-methanol as a base, it optimizes combustion by compounding with oxygen-containing components such as 2-MTHF and DMM / MF, achieving rapid ignition, emission reduction, and noise reduction. Phase behavior is regulated by isobutanol and polyether-modified silicon, achieving a reversible and stable phase without the need for high-HLB surfactants, preventing deposition and gas lock. A four-fold protective barrier is constructed using GMO and fluorinated silica polyethers, combined with antioxidant synergy to achieve corrosion resistance and aging resistance. The process adopts a sequential design of front-end purification – mid-stage two-phase construction – and end-stage static mixing, achieving low-energy homogenization and ensuring storage, transportation, and operational stability.

This invention discloses a Bacillus subtilis ( Bacillus subtle The EB-8 strain, deposited on January 14, 2026, at the China General Microbiological Culture Collection Center (CGMCC) with accession number CGMCC No. 37320, is disclosed. The application of Bacillus subtilis strain EB-8 in the fermentation modification of tartary buckwheat flour is also disclosed. This invention's Bacillus subtilis strain EB-8 can significantly increase the amylose content of tartary buckwheat, helping to inhibit starch retrogradation and improve its freeze-thaw stability; simultaneously, it increases the total flavonoid and total phenolic content of tartary buckwheat, enhancing its antioxidant activity. Furthermore, this strain can selectively retain and enrich essential amino acids such as lysine and methionine, reduce bitter components, improve taste, and facilitate the formation of a cereal matrix suitable for cold processing, with a mild taste and enhanced oxidative defense. Overall, it achieves synergistic optimization of the functional activity and processing characteristics of tartary buckwheat flour, which is beneficial for the high-value utilization of tartary buckwheat flour resources.
