如何计算变压器铁芯截面积春晨JFEYH高压电机引接线JFEYH高压电机引出线
How to calculate the intercepting area of transformer core
如何计算变压器铁芯截面积小型单相变压器多采用壳式铁芯，变压器铁芯截面积与变压器的容量有关，一般按下列经验公式计算。 A=k√s(cm2)式中，s为变压器的容量；k为系数。硅钢片的k值见表。表 铁芯净截面系数的经验数据根据计算得到的A值，可 ...
How to calculate the cross-sectional area of transformer core is mainly used in small single-phase transformers. The core area of transformer is related to the capacity of transformer. It is usually calculated according to the following empirical formula. A=k root s (cm2) type, s for transformer capacity; K coefficient. The K value of silicon steel sheet is shown in the table. The empirical data of the net section coefficient of the iron core can be calculated according to the calculated A value.

变压器的基本结构和工作原理
Basic structure and working principle of transformer
变压器的基本结构是由铁芯和绕组（线圈）组成的。变压器铁芯是由两面涂有绝缘漆的硅钢片叠装而成的。绕组是绕在铁芯上的两个匝数不等的线圈，与电源相连的绕组称为一次绕组，与负载相连的绕组称为二次绕组。变压器就 ...
The basic structure of a transformer consists of a core and a winding (coil). The iron core of the transformer is made up of two silicon steel sheets coated with insulating varnish. A winding is a coil of two turns around an iron core. The winding connected to the power is called a primary winding, and the winding connected to the load is called the two winding. The transformer is...

照明线需要装漏电保护？听老师傅一讲完，我才知道我家就装错了
Does the lighting line need leakage protection? After listening to the teacher, I knew that my house was wrong.
照明线需要装漏电保护？听老师傅一讲完，我才知道我家就装错了装修的时候，电工会帮家里做好漏电保护装置。大家应该都知道，漏电保护既是开关也是装置。它在一个家里的作用之大不用多说。如果家里泄漏电的话，它就会自动断开电源，保护电路，避免人体触电。那么像家里照明灯需不 ...
Does the lighting line need leakage protection? After listening to the teacher, I knew that when my house was decorated, the electrician would help the home to do the leakage protection. It should be known that leakage protection is both a switch and a device. It doesn't have to say much about the role of a family. If the electricity is leaking at home, it will automatically disconnect the power, protect the circuit and avoid the electric shock of the human body. So like home lights need not...
