如何計算變壓器鐵芯截面積春晨JFEYH高壓電機引接線JFEYH高壓電機引出線

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 ...

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...

照明線需要裝漏電保護？聽老師傅一講完，我才知道我家就裝錯了

Does the lighting line need leakage protection? After listening to the teacher, I knew that my house was wrong.

照明線需要裝漏電保護？聽老師傅一講完，我才知道我家就裝錯了裝修的時候，電工會幫家里做好漏電保護裝置。大家應該都知道，漏電保護既是開關也是裝置。它在一個家里的作用之大不用多說。如果家里泄漏電的話，它就會自動斷開電源，保護電路，避免人體觸電。那么像家里照明燈需不 ...

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...
