    摘要： Disclosed is an electrical transformer for improved transformer power capacity and efficiency designed by the application of disclosed design considerations. One embodiment design consideration is a method to configure power transformer windings wherein the minimum distance of the primary windings from the winding axis/core center is greater (the primary windings are more distal) from the winding axis than the minimum distance of the secondary windings, which are wound around the minimum interior core diameter. This design consideration is extended from single bobbin transformer designs to split bobbin designs, with the requisite distal increase of the primary windings (from the core axis) geometrically provided by an enlarged core bobbin center leg (axial) dimension beneath the primary winding window. Another disclosed design consideration is to fix the primary winding length relationship to the core weight for given transformer specifications in accordance with the disclosed unexpected experimental results and formula.

    摘要翻译： 公开了一种电变压器，用于通过应用公开的设计考虑来改进设计的变压器功率容量和效率。 一个实施例设计考虑的是一种配置电力变压器绕组的方法，其中绕组轴线/铁芯中心的初级绕组的最小距离比绕组轴线比次级绕组的最小距离更大（初级绕组更远） 其围绕最小内芯直径缠绕。 这种设计考虑从单筒管变压器设计扩展到分裂筒管设计，其中初级绕组（从芯轴线）必需的远程增加几何地由初级绕组窗口下方的放大芯轴筒中心腿（轴向）尺寸提供。 另一个公开的设计考虑是根据所公开的意想不到的实验结果和公式，将给定变压器规格的初级绕组长度关系固定在芯重上。

    摘要： A current transformer assembly for harvesting power from a primary conductor, such as a power line, for operating electronics, where the assembly is secured to the conductor while the conductor is connected. The assembly includes a current transformer having a transformer structure with a central opening that accepts the primary conductor and a spindle member for accepting a current transformer magnetic tape operating as the core of the current transformer. The assembly also includes a tape carrier secured to the structure on which the transformer tape is wound, and a winding device operable to unwind the transformer tape from the tape carrier and wind the tape onto the spindle member.
