摘要： The noise suppression method of individual active noise reduction system comprises the steps that: (1) initial noise digital signals are received and converted to serve as input signals of a BP neural network; (2) the input signals are processed to generate secondary digital signals; (3) the secondary digital signals are output to a loudspeaker and secondary noise is generated; (4) remained noise digital signals obtained by overlapping the initial noise and the secondary noise are received; whether remained noise digital signals is continuously constant for the set times is judged; if yes, the secondary digital signals are kept outputting; (5) if not, BP neural network parameters are optimized and adjusted with the amplitude of the remained noise digital signals being minimum as the optimality principle; remained noise digital signals of previous step are served as new input signals and the step (2) is executed again.

摘要： A common mode inductor includes a bobbin with two windings. A first winding is positioned between a first end flange and a first offset flange. A second winding is positioned between a second end flange and a second offset flange. The windings are spaced apart by a center section without windings. A pair of E-cores, each having a pair of outer legs and a center leg, are positioned in a passageway of the bobbin such that the center leg of each E-core is surrounded by a respective one of the two windings. An I-bar is positioned in the center section of the bobbin between the two offset flanges with the I-bar perpendicular to the outer legs and the center legs of the two E-cores. The I-bar core increases leakage inductance between the two windings to improve the suppression of electromagnetic interference caused by common mode noise in the two windings.

摘要： A high-gradient internal-circulating oil-cooled Magnetic Separator, includes magnetic system coils, an internal-circulating oil path system, an external-cooling system and an oil conservator. The magnetic system coils are used for generating excitation magnetic field to achieve the iron-absorption function, the magnetic paths of the magnetic system coils being an open magnetic path structure. The internal-circulating oil path system is used for allocation and collection circulation of transformer oil. The external-cooling system is used for heat dissipation of transformer oil to achieve internal heat dissipation balance. The oil conservator is used as a supplementary container for the transformer oil expansion during the apparatus's operation. An internal-circulating structure is employed, and external-circulating pipes are simplified, circulating resistance in oil paths being reduced, problems including complex interference in oil paths arrangement, low circulation efficiency, leakage at welding spots, etc. being avoided, ensuring normal operation, and enhancing efficiency of iron removing.
