电气专业英语section 1-5中英

由于节点3连接有4条支路，所以选择其作为参考点，用所示的接地符号标明。
The voltage between node 1 and the reference node 3 is identified as u1, and u2 is defined between node 2 and the reference.

每个非参考点相对于参考点的电压既是节点电压。
It is common practice to select polarities so that the node voltages are positive relative to the reference node.

选择极性时，通常使节点电压相对于参考点为正。

电气工程及其自动化专业英语课文翻译

unit1 taxe A 电力变压器的结构和原理在许多能量转换系统中，变压器是一个不了缺少的原件。

它使得在经济的发电机所产生电能并以最经历的传输电压传输电能，同时对于特定的使用者合适的电压使用电能成为可能。

变压器同样广泛的应用于低功率低电流的电子电路和控制电路中，来执行像匹配电源组抗和负载以求得最大的传输效率。

隔离一个电路与另一个电路在两个电路之间隔离直流电而保证交流电继续通道的功能。

在本质上，变压器是一个由两个或多个绕组通过相互的磁通耦合而组成的，如果这其中的一个绕组，原边连接到交流电压源将产生交流磁通它的幅值决定于原边的电压所提供的电压频率及匝数。

感应磁通将与其他绕组交链，在副边中将感应出一个电压其幅值将取决于副边的匝数及感应磁通量和频率。

通过使原副边匝数比例适应，任何所期望的电压比例或转换比例都可以得到。

变压器工作的本质仅要求存在与两个绕组相交链的时变的感应磁通。

这样的作用也可以发生在通过空气耦合的两组绕组中，但用铁心或其他铁磁材料可以使绕组之间的耦合作用增强，因为一大部分磁通被限制在与两个绕组交链的高磁导率的路径中。

这种变压器通常被称作为心式变压器。

大部分变压器都是这种类型。

以下的讨论几乎全部围绕心事变压器。

为减少铁心中的涡流所产生的损耗，磁路通常由一叠薄的叠片所组成。

如图1.1所示两种常见的结构形式用示意图表示出来。

芯式变压器的绕组绕在两个矩形铁心柱上，壳式变压器的绕组绕在三个铁心柱中间的那个铁心柱上，。

0.14毫米厚的硅钢片通常被用于在低频率低于几百Hz下运行的变压器中，硅钢片具有价格低铁心损耗小，在高磁通密度下，磁导率高的理想性能，能用做高频率低能耗的标准的通讯电路中的小型变压器的铁心是由被称为铁氧体的粉末压缩制成的铁磁合金所构成的。

在这些结构中，大部分的磁通被限制在固定的铁心中与两个绕组相交链。

绕组也产生多余的磁通，像漏磁通，只经过一个绕组和另外的绕组不相交链。

虽然漏磁通只是所有磁通的一小部分，但它在决定变压器的运行情况中起着重要的作用。

Although they are very important concepts, series/parallel equivalents and the current/voltage division principles are not sufficient to solve all circuits. Series/Parallel Equivalents are useful to solve simple circuits (is composed of single source and multiple resistances can be reduced by series/parallel equivalents ) Complex circuits are typically composed of multiple sources or multiple resistances can not be reduced by series/parallel equivalents.

2.4 Branch current analysis
•The first and most straightforward complex network analysis technique is called the Branch Current Method. •Let the branch currents be unknowns, write equations describing their relationships to each other through Kirchhoff's and Ohm's Laws. •Give rules to write b independent equations to find currents of b branches. •For the network with b branches and n nodes, use KCL to write n-1 current equations and use KVL to write b(n-1) independent voltage equations.

电气专业英语课文翻译

An electric circuit (or network) is an interconnection of physical electrical device. The purpose of electric circuits is to distribute and convert energy into some other forms. Accordingly, the basic circuit components are an energy source (or sources), an energy converter (or converters) and conductors connecting them.电路（或者网络）是物理电气设备的一种互相连接。

电路的目的是为了将能量分配和转换到另外一种形式中。

因此，基本的电路元件包括电源、电能转换器以及连接它们的导体。

An energy source (a primary or secondary cell, a generator and the like) converts chemical, mechanical, thermal or some other forms of energy into electric energy. An energy converter, also called load (such as a lamp, heating appliance or electric motor), converts electric energy into light, heat, mechanical work and so on.电源（原生电池或者再生电池、发电机等类似装备）将化学能量、机械能量，热能或者其他形式的能量转换成电能。

电能转换器（也称为负载，如灯泡、电热器或者电动机）将电能转换成光、热、机械运动等等。

电气工程及其自动化专业英语第一章课文翻译

第一章第一篇sectiongTwo variables u(t) and i(t) are the most basic concepts in an electric circuit, they characterize the various relationships in an electric circuitu(t)和i(t)这两个变量是电路中最基本的两个变量，它们刻划了电路的各种关系。

Charge and CurrentThe concept of electric charge is the underlying principle for explaining all electrical phenomena. Also, the most basic quantity in an electric circuit is the electric charge. Charge is an electrical property of the atomic particles of which matter consists, measured in coulombs (C).电荷和电流电荷的概念是用来解释所有电气现象的基本概念。

也即，电路中最基本的量是电荷。

电荷是构成物质的原子微粒的电气属性，它是以库仑为单位来度量的。

We know from elementary physics that all matter is made of fundamental building blocks known as atoms and that each atom consists of electrons, protons, and neutrons. We also know that the charge e on an electron is negative and equal in magnitude to 1.60210×10 19C, while a proton carries a positive charge of the same magnitude as the electron. The presence of equal numbers of protons and electrons leaves an atom neutrally charged.我们从基础物理得知一切物质是由被称为原子的基本构造部分组成的，并且每个原子是由电子，质子和中子组成的。
