对于本发明而言磁材的选择非常重要, 由于管道传输信号属于微弱信号, 有 相当范围的带宽, 信号变换时要求损耗小, 对磁性材料的选择有一定的要求: 根据磁路的基本定律: 安培环路定律: N*I=H*1;  For the present invention, the selection of the magnetic material is very important. Since the pipeline transmission signal is a weak signal, there is a considerable range of bandwidth, and the loss is small when the signal is converted, and there are certain requirements for the selection of the magnetic material: According to the basic law of the magnetic circuit: Ampere loop law: N*I=H*1;

磁芯损耗  Core loss
磁芯损耗 Pt包括磁滞损耗 Ph、 涡流损耗 Pe、 剩余损耗 Pc。  Core loss Pt includes hysteresis loss Ph, eddy current loss Pe, residual loss Pc.
磁滞损耗 Ph是磁滞回线围成的面积, 频率越高, Ph越大, 磁感应摆幅越大, 包围的面积越大, 损耗越大。 The hysteresis loss Ph is the area enclosed by the hysteresis loop. The higher the frequency, the larger the Ph, and the larger the magnetic induction swing. The larger the area enclosed, the greater the loss.
涡流损耗 Pe线圈中流过的激励电流在磁芯本身周围感应出感应电势,因磁材 的电阻率不是无限大, 感应电压产生电流 Ie——涡流, 该项电流流过电阻引起涡 流损耗。 涡流损耗与频率无关, 但与磁材的电阻率成正比。  Eddy current loss The excitation current flowing in the Pe coil induces an induced potential around the core itself. Since the resistivity of the magnetic material is not infinite, the induced voltage generates a current Ie, which is an eddy current, and the current flows through the resistor to cause eddy current loss. The eddy current loss is independent of frequency, but is proportional to the resistivity of the magnetic material.
剩余损耗 Pc由磁化弛豫效应或磁滞后效应引起的损耗。  The residual loss Pc is a loss caused by a magnetization relaxation effect or a magnetic hysteresis effect.

因此对于本发明而言的高频耦合器  Therefore, the high frequency coupler for the present invention
