变电器与噪声传输

理想变压器理论上是极致的电路元件,它可用双口RJ45带滤波器价格极致的磁藕合在初中级和次级绕组中间传输电磁能。理想变压器只有传输交替变化的差模电流量。它不可以传输共模电流量,由于共模电流量在变电器绕阻两边的电势差为零,不可以在变电器绕阻上造成电磁场。

具体变电器初中级和次级绕组中间有一个不大但不等于零选购RJ45带滤波器选型的耦合电容CWW。

这一电容器是绕阻中间存有非电解介质和物理学空隙所造成的。提升统组中间的间隙和用低导热系数的原材料铺满统绕阻中间的室内空间就能减少绕阻中间电容器的标值。电容器Cww为共模电流量出示一条越过变电器的安全通道,其特性阻抗是由容量的尺寸和数据信号頻率来决策的。
