Unit 2 TRANSFORMERA: TransformerUse of TransformersIf an inventory were taken if the electrical appliances in the home or of the modern electrical equipment in industry that has been added in the past ten years, it would be found that the use of electrical appliances and equipment has greatly increase. The demand for electrical power has more than doubled in the past ten years and it is predicted that the demand will double again in less than ten years. This increase along with the trend of people and industry to migrate to the suburbs has created the problem of transmitting larger amounts of electrical power over longer distances than ever before.Fortunately, there is at our disposal a ―Transformer‖ which is a piece of electrical supply equipment that makes it possible to efficiently transmit large amounts of electrical power over long distances. In construction a transformer is an efficient, relatively simple, quiet device that has no moving parts thus limiting maintenance costs. Although it is simple in construction, it is somewhat complex in operation.Increase of VoltageThe transformer is used in the transmission and distribution of power to reduce the conductor size in line construction. Electric power, being the product of voltage and current, may result from multiplying a very large current by a very small voltage; that is, in transmitting any given power, if the voltage factor is increase. Electrical voltage ( volts) is the force which moves electrons through conductors to result in current (amps) flow. As the cross-section or size of the line conductors is determined by the amount of current it will carry, it may be smaller in size if the current is decrease.It has been found that the size of the conductor necessary for transmitting a given amount of power a given distance depends inversely upon the square of the voltage, that is, if the voltage between transmission lines is doubled, a conductor only one-fourth as large is necessary to transmit the same power over the same distance with the same line loss. If the voltage is increase three times, the size of the line conductor is only one-ninth.In the transmission of electrical power the function of the transformer is to raise or ―step-up‖ the voltage at the generator to a much higher value, thus reducing the size of the transmission conductor. It is obvious that the installation and maintenance cost will be less for a smaller conductor.Alternating current generators (alternators) normally produce voltages of up to 22,000 volts which must in turn be stepped-up to a higher voltage for economical transmission to the load or to the place where the power will be used. To transmit industrial loads for short distances or for low power demand areas such as residential the transmission lines usually operate at voltages of 12,470; 13,200; 13,800 or 14,400. To transmit large amounts of power over a considerable distance very high voltages are necessary. Experimental work has progressed to the point where engineers have found that voltages of 750,000 volts can be successfully and economically used over relatively short distances. For longer distances an even higher voltage is used. The transmission lines which carry power from Boulder Dam to the west coast operate at a voltage of about 500,000 volts. It may be of interest that even at this extra high voltage, special design is used for the transmission lines to reduce their weight. They are constructed of interlocking sections of hollow aluminum tubes which permits them to be strung between widely-separated towers.Reduction of V oltageWhile it is desirable to resort to very high voltages for transmission purposes, such voltages are undesirable when electrical power is distributed among buildings or within densely populated areas. It is the function of a transformer to lower or step-down the voltage at the load or the building where the power is to be used to a value that is safe and economical for use inside a residential, commercial or industrial building. For residential wring, the normal voltage is 115/230 volts, whereas the voltage in a commercial or industrial building is usually 120/380 volts for appliances and incandescent lighting and 277/480 volts for fluorescent light and power. In large commercial buildings and industrial plants the modern trend is to use a 12,470 to 24,000 volt distribution system. Power at this voltage delivered to substations within the building where transformers step down the voltage to the level needed.Useful Expressions in Passage AB: THE IMPACT OF INRUSH CURRENTS ON THE MECHANICAL STRESS OF HIGH VOLTAGE POWER TRANSFORMER COILSPOWER transformers in electric systems are one of the most cost effective apparatuses. Breakdown causes high costs for repair or replacement and may often lead to very high costs due to temporary loss of the power delivery capability. Therefore, power transformers are highly protected against various causalities of failure. One major reason for internal faults is attrition of the winding and conductor insulation due to vibrations initiated by the electromechanical forces at service current and over currents. Accordingly, the coils of transformers are mechanically supported and prepressed by bandages, wedges, and heavy bolts. The dimensioning criteria forthese support structures are usually the forces caused by the highest possible current peak that normally occurs under short circuit (SC) conditions. Therefore, type testing of transformers ask for SC tests only, as it is assumed that this is the worst case with regard to the maximum forces.In the past, it was discussed very often in several panels to what extend inrush current (IR) currents are a jeopardy for the transformer windings（变压器绕组）. As it is well known, the value of these IR currents occurring when energizing unloaded transformers can be in the same order of magnitude as a fault current, thus producing significant electromagnetic forces. The difference to SC is that the IR may last for several tens of seconds, whereas a fault normally is cleared within tens of milliseconds. In addition, an IR situation is much more frequently as this can be considered as normal service operation.Recent cases of insulation failures in power transformers that were frequently energized under no load condition support the suspicion of many people that IR currents have a jeopardous effect. It is assumed that due to the unbalanced magnetomotive force (MMF) and high saturation of the transformer core local (axial) forces under severe IR conditions, especially on the tap changer (TC) coils, could exceed the values taken as dimensioning basis. So, it seems likely possible that conductor and winding insulation is damaged due to mechanical overstress at IR.Although it is requested by many utilities that high IR currents shall indeed be avoided from a systems operation point of view, possible damaging effects to the transformer itself have rarely been investigated. To the author’s knowledge, only one paper deals with forces on transformer windings at IR conditions where it is shown that the windings exhibit fairly large axia l forces, exceeding those built up under short circuit conditions.Out-of-phase synchronization may also cause unbalanced MMF conditions in step up transformers. Force calculations show that the axial forces in the windings can be two to ten times higher than under SC conditions. However, the magnetic field patterns caused by such erroneous operations are different to the ones at IR conditions, because when energizing unloaded transformers the secondary (mostly the low voltage) side is not excited at all.A first rough estimation of the distribution of the radial magnetic field component along transformer coils was presented in [4]. The results show that the local radial magnetic field at the ends of tap changer coils to be up to 80% higher at IR compared to SC conditions, assuming the IR current to be as high as the SC current.In order to learn more about how the IR current produces mechanical forces to the transformer windings, the situation of a three-legged step up transformer was modeled by means of a suitable computer code. Two-and three-dimensional calculations were carried out. The goal was to calculate the forces in qualitative comparison to those that occur at SC. The result should also give information on the technical benefit if the IR current is avoided by controlled switching, which seems to be the most effective approach for the time being.Starting with general statements on force calculations the following chapter will explain reasons for choosing 2-D finite-element method (FEM) and how the mechanical stress on the coils was calculated from the local magnetic stray field density.Useful Expressions in Passage BC：简历Resume of Personal ExperienceName: Wei WangDate of Birth: September 18, 1977Age: 26 yearsSchool Graduated: North Jiaotong UniversityTime Graduated: July 1999Major: electric engineeringDegree: BachelorLevel of English: Fourth grade of Nation.

经典外文翻译(电气工程专业英语2)
电力电子结构单元：一种电力电子的系统化方法在过去的五年中，美国海军已经通过电力电子机构单元这个软件（PEBB）投入了很多在电力电子技术上。
这种投资对于现在和未来的美海军舰艇是至关重要的。
同时，它对于电力电子工业也是至关重要的。
有一些像因特网一样的投入，对整个社会都是有利的。
美国国防部高级研究计划局（DARPA）开发因特网以实现防御的功能。
现在一个宏伟的工业已经因为这种投资而发展了起来。
没有哪一家公司或者私人组织可以独立承担的器开发互联网的费用。
投入的回报有可能对整个社会是有很大益处的，但是对于任何一个组织而言，这是一种巨大的负担。
像因特网一样，PEBB软件集中于核心问题并且试图确认将来美国海军的需要可以被商业现成产品系统技术满足。
这是一个理想的双赢的情况，美海军得到了价格合理的电力电子技术，电力电子工业得到了核心技术和科学的的支持，否则这对于他们来说是支付不起的。
美国海军促进了这些核心概念的开放存取和相应技术实施之间的竞争。
许多现代的范例已经通过PEBB软件研究来适应电力电子技术。
这些范例比方有开放的即插即用的体系结构、多单元设计、多层次设计、集成和同步工程。
即插即用功率即插即用的的体系结构把电力电子系统设计的更像一个个人电脑。
电力模型被插入它们的应用程序中并且自行运转。
运行程序可以判断出什么进入了，谁制作的，并且知道怎样去运行。
每一个电力模型会维持它们本身的安全运行限制。
这些视觉上的视线需要组织来开发标准的界面和协议。
即插即用体系结构的动机之一就是更低的成本和更多的程序功能。
新型电力电子产品的要求超越了供给它们功能的资源。
有能力做这件事的人非常难寻觅。
下一代的工程师更倾向于成为电脑或者软件工程师而不是电力电子工程师。
它们希望在它们的电脑上完成系统设计，而那些电力部分可以像他们的电子产品一样自动得到。
电力电子的绝大部分是传统的设计。
如果每一个人得到一台电脑必须要有设计师来设计所有的面板和包装，软件工程师来设计汇编语言和运行程序的开发，那么个人笔记本的产业还会有吗？这不就是古老的IBM360（主体框架电脑）方式吗？拥有将专业技术制作成设备的开放设计体系使设计者事倍功半，并且使专业知识可以应用于越来越多的程序。

• No such limitation is placed on an alternating-current machine; here the only requirement is relative motion, and since a stationary armature and a rotating field system have numerous advantages, this arrangement is standard practice for all synchronous machines rated above a few kilovolt-amperes.

倒译法
• Various machine parts can be washed very clean and will be as clean as new ones when they are treated by ultrasonics, no matter how dirty and irregularly shaped they may be. • 各种机器零件无论多么脏，形状多么不规则，当它们用超 声波处理后，就可以被洗得非常干净，甚至干净得像新的 零件一样。

长句的翻译
• 翻译长句子时，必须分析清楚原文的结构关系，在理解原文内 容的基础上，分清主次，按照时间概念和逻辑顺序重新按汉语 习惯加以组合处理，译出的句子既要准确地表达原文，又要符 合汉语的习惯。常用的译法有顺译法、倒译法、分译法。 • 顺译法是基本上保留原文的语法结构，依照原文顺序译出。一 般地，当原文的语法结构和时间顺序与汉语相同时，可采用顺 译法。在翻译过程中，根据具体情况，可增加或省略有关连接 词。例如：
• 理论科学分为自然科学和生物科学。前者研究自然界的各种事 物和其相互关系，而后者则探讨地球上生物的发展历史和活动。 • （先要点，再补充说明）
45-10
45-8
分译法
• 为了汉语表述的方便，可将原文的长句拆开来分别译出。 当长句中的主句与从句或介词短语及分词短语等多修饰的 词与词之间的关系不是很密切，并且各自具有相对的独立 意义时，可分解成几个部分或意思层，然后再按时间顺序、 逻辑顺序有机的组合在一起，还可以增减适当的词语以便 断句之间的衔接。例如，可添加或利用原文中的总括性词 语作为引语，而后分述各个部分；或先将某一短语和从句 分出去单独译出，在利用总括性词语把它和主句联系到一 起；或先译出原文的要点，再将次要部分作为补充说名译 在后面。
交流发电机不受任何限制，惟一的要求是相对移动，而且由于 固定电枢及旋转磁场系统具有许多优点，这种安排是所有额定
容量超过几千伏安的同步发电机的标准做法。
45-5
顺译法例句（2）
• For large motors, therefore, a phase-winding rotor is used, with the winding connected at one end to each other and at the other end to slip-rings, thus enabling the resistance of the rotor to be varied at will, providing a greater starting torque and some speed control.
• 因此，对于大型电机来说，一般采用相绕组转子，其绕线的一 端互相连接，而另一端接于轴的滑环上，这样，可随意改变转 子的电阻，从而可提供更大的起动转矩，并可适当控制速度。
45-6
倒译法
• 当原文结构层次与汉语相反时，要从英语原文的后面译起， 自下而上，逆着原文的顺序翻译，称为倒译法。例如：
The resistance of any length of a conducting wire is easily measured by finding the potential difference in volts between its ends when a known current is flowing . 已知导线中的电流，只要求出导线两端电位差的伏特数，就 不难测出任何长度的导线的电阻。

专业英语的语法特点
• 惯用时态。专业英语中多用动词的现在时，尤其是多用一般 现在时，来叙述事实或真理，客观地表述定义、定律、定理 方程式、公式、图标等。用一般过去式来介绍试验情况或叙 述事物的历史发展经过等。用一般将来时叙述计划要做的工 作和预期获得的结果等。 大量使用被动语态。专业英语更注重对事实、方法、性能和 特性做出客观表述。采用被动语态能更为客观，有助于将读 者的注意力在描述的事物、事实、现象或过程上。 大量使用非限定动词。在专业英语中，为了描述的明确、简 练，多采用不定式短语、分词短语，特别是分词短语应用较 多。

大量使用名词及介词短语。同样是为了达到明确和简练的要 求，在专业英语中多采用名词和介词短语。 条件句较多。专业文献中常需提出假设和推理，因而条件句 使用较多。 长句较多。由于专业英语的作用是陈述事理、描述过程，它 所给出的定义、定理、定律或描述的概念及工艺过程，都必 须严谨、准确。由此，与日常英语相比，使用的长句较多。 有时一个长句就是一个较长的段落。
