無功補償如何提高功率因素

How to improve power factors by reactive power compensation

無功補償如何提高功率因素首先了解什么是功率因數(shù)?功率因數(shù)：是用來衡量用電設備（系列用電設備，電網(wǎng)的變壓器、傳輸線路，等等）的用電效率的數(shù)據(jù)。功率因數(shù)的定義公式：功率因數(shù)＝有功功率/視在功率。有功功率：是設備消耗了的，轉換為其他 ...JEM電機引接線JEM電機引出線JEM電纜

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...

如何計算變壓器鐵芯截面積

How to calculate the intercepting area of transformer core

如何計算變壓器鐵芯截面積小型單相變壓器多采用殼式鐵芯，變壓器鐵芯截面積與變壓器的容量有關，一般按下列經(jīng)驗公式計算。 A=k√s(cm2)式中，s為變壓器的容量；k為系數(shù)。硅鋼片的k值見表。表 鐵芯凈截面系數(shù)的經(jīng)驗數(shù)據(jù)根據(jù)計算得到的A值，可 ...JEM電機引接線JEM電機引出線JEM電纜

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.

變壓器的基本結構和工作原理

Basic structure and working principle of transformer

變壓器的基本結構是由鐵芯和繞組（線圈）組成的。變壓器鐵芯是由兩面涂有絕緣漆的硅鋼片疊裝而成的。繞組是繞在鐵芯上的兩個匝數(shù)不等的線圈，與電源相連的繞組稱為一次繞組，與負載相連的繞組稱為二次繞組。變壓器就 ...

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...
