differentiation transformer

用法例句

By means of differentiation transformer coupling between the control unit and the main circuit, an ideal isolation coupling can be achieved with a high coefficient of coupling and small interwinding capacitance as well as fast response and high common mode rejection.

研究了采用微分变压器实现理想的隔离耦合,探测集电极电压实施运行监控与脉宽限流式保护;采用“贝克箝位”的原理实现临界饱和状态工作,探测输出电流的变化率,预报大电流的出现,实现无延迟的速断保护与短路运行,同时给出了GTR理想的基极驱动电流的一种自适应的基极驱动的原理电路。

In order to calculate the short-circuit impedance of the transformer with split types of windings exactly,the multi-winding inductance matrix(IM) for the multi-branch of the high-voltage winding and one of the low-voltage split winding was first established by three-dimensional finite element method(FEM) with ANSYS software.

为准确计算出分裂变压器高、低压绕组间的短路阻抗,首先采用ANSYS的三维静态磁标势法数值计算得出高压多并联支路与单个低压绕组间的多绕组电感矩阵,并依据电路理论将其简化为等效双绕组电感矩阵,进而得到短路阻抗百分比,并推导了高压各并联支路电流分配,最后给出一个概念设计的分裂式高温超导变压器算例。
