变压器的通量密度(B)是多少?

通量密度是核心内部磁通的强度. 这取决于核心材料。标准硅钢芯一般运行于1.0至1.4特斯拉而不饱和.

如何计算每伏转弯?

转弯-每伏用公式计算: Tv = 10^4 / (4.44 * f * B * Ac),其中 Ac 为克米2中的核心截面面积; f为Hz中频率; B为特斯拉中通量密度.

应当使用什么当前密度(J)?

电流密度是电线截面单位的电流. 对于标准连续运行的变压器,建议用2.5至3.5 A/mm2来保持低温上升.

选择一级和二级电压(如230V至12V).
指定VA中的变压器容量(或装入Amps中的电流)和频率(50Hz或60Hz).
审查估计的核心领域、转弯计数、转弯/伏特系数和电线测量建议.

{姓名}是什么来着?

一个变能器由磁核和两个或两个以上的伤口圈组成. 诸如转弯-每伏和核心交叉区等设计参数对于防止核心饱和和并最大限度地提高效率至关重要.

这个计算器根据磁通密度,电压目标,和频率来估计一级和二级线圈转动. 它还建议使用当前密度标准对两个线圈进行线程测量。
