无功补偿如何提高功率因素

How to improve power factors by reactive power compensation

无功补偿如何提高功率因素首先了解什么是功率因数?功率因数：是用来衡量用电设备（系列用电设备，电网的变压器、传输线路，等等）的用电效率的数据。功率因数的定义公式：功率因数＝有功功率/视在功率。有功功率：是设备消耗了的，转换为其他 ...JEM电机引接线JEM电机引出线JEM电缆

How to improve the power factor of reactive power compensation is to know what power factor and power factor first. It's a data to measure the electricity efficiency of electrical equipment (series of electrical equipment, power transformers, transmission lines, etc.). The definition formula of the power factor: the power factor = the active power / the view in the power. Active power: the equipment is consumed, converted to other...

如何计算变压器铁芯截面积

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 ...JEM电机引接线JEM电机引出线JEM电缆

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...
