【正文】 uction of electricity transmission and distribution in the whole process, its effect is obviously very important. In the whole power system, the capacity of transformer is usually about generator capacity of more than 3 times. There are a variety of the role of the transformer can not only increase the voltage electricity to electricity, also can reduce the voltage to use voltage at various levels, to meet the need of electricity. All in all, stepup and stepdown must be pleted by the transformer. In power system in the process of transmitting electricity, will inevitably produce voltage and power loss, voltage loss when conveying the same power is inversely proportional to the voltage, power loss varies inversely as the square of the voltage. Use of transformer to improve the voltage, reduces the power loss. When transform voltage of transformer. Is under the same frequency make the other side with a different measuring of voltage and current. Because of conservation of energy, the second time to measure with a measuring current and voltage change is on the contrary, one side is the voltage of the circuit, then the side of the current will decrease。 On the other hand, the current will increase when the voltage reduction. When the transformer is not we are not bound to the electricity quantity bigger or smaller. In the process of power shift, because the transformer itself consumes a certain energy, thus the total energy of input transformer shall be equal to the output energy and the consumption of transformer stupid body energy. Because of lack of rotating transformer parts, no mechanical losses at work, and new products in the design and structure, process, etc adopted many effective measures of energy saving, so its work efficiency is very high. Usually the efficiency of no less than 95% of small and medium sized transformer large capacity transformer efficiency can reach more than 98%. 中文翻譯 變壓器是一種靜止的電氣設(shè)備,屬于一種旋轉(zhuǎn)速度為零的電機(jī)。它是發(fā)電廠和變電所的主要設(shè)備之一。電力變壓器在系統(tǒng)中工作時(shí),可以將電能由它的一次測經(jīng)電磁能量的轉(zhuǎn)換傳輸?shù)蕉螠y,同時(shí)根據(jù)輸配電的需要將電壓變高或變低。所以,變壓器在電能的生產(chǎn)傳輸和分配使用的全過程中，其作用顯然十分重要的。在整個(gè)電力系統(tǒng)中，變壓器的容量通常約為發(fā)電機(jī)容量的3倍以上。 變壓器的作用是多方面的不僅能升高電壓把電能送到用電地區(qū)，還能把電壓降低為各級使用電壓，以滿足用電的需要?？傊?，升壓與降壓都必須由變壓器來完成。在電力系統(tǒng)傳送電能的過程中，必然會(huì)產(chǎn)生電壓和功率兩部分損耗，在輸送同一功率時(shí)電壓損耗與電壓成反比，功率損耗與電壓的平方成反比。利用變壓器提高電壓，減少了送電損失。變壓器在變換電壓時(shí)。是在同一頻率下使其二次側(cè)與一次測具有不同的電壓和不同的電流。由于能量守恒的緣故，其二次測與一次測的電流與電壓的變化是相反的，即要使某一側(cè)電路的電壓升高時(shí)，則該側(cè)的電流就必然減少；反之，當(dāng)電壓降低時(shí)電流就一定增大。變壓器并不時(shí)也決不能將電能的量變大或變小。在電力的轉(zhuǎn)變過程中 ，因?yàn)樽儔浩鞅旧硪囊欢芰?，因此輸入變壓器的總能量，?yīng)等于輸出的能量加上變壓器笨身消耗的能量。由于變壓器無旋轉(zhuǎn)部分，工作時(shí)無機(jī)械損耗，而且新產(chǎn)品在設(shè)計(jì)和結(jié)構(gòu)、工藝等方面采取了眾多節(jié)能的有效措施，所以它的工作效率很高。通常中小型變壓器的效率不低于95％，大容量變壓器的效率則可達(dá)98％
