變壓器是一種相對(duì)靜止的電氣設(shè)備，由繞在同一個(gè)鐵心上的兩個(gè)或兩個(gè)以上的繞組組成的，繞組之間通過(guò)交變的磁通的相互聯(lián)系。為了把發(fā)電廠發(fā)出的電能經(jīng)濟(jì)的傳輸、合理的分配以及安全的使用，都要用到電力變壓器。 </p> <p> 2、變壓器工作原理 </p> <p> 簡(jiǎn)單說(shuō)變壓器的工作原理就是“電生磁，磁生電”。變壓器的初級(jí)（一次）線圈和次級(jí)（二次）線圈共同繞在一個(gè)鐵芯上，當(dāng)一次線圈通入電壓U1后，在鐵芯中產(chǎn)生交變磁通，這個(gè)磁通穿過(guò)一次繞組和二次繞組，根據(jù)電磁感應(yīng)定律，在一次繞組和二次繞組中分別產(chǎn)生感應(yīng)電勢(shì)E1和E2。根據(jù)電磁感應(yīng)定律可知，一次側(cè)、二次側(cè)繞組的感應(yīng)電勢(shì)分別為：E1/E2=U1/U2=N1/N2=K(k為變比) </p> <p> <br /> </p><p style="text-indent:25px">屏蔽物：冷卻劑有的變壓器利用液態(tài)物質(zhì)的循環(huán)進(jìn)行熱量的疏散。常用的液態(tài)物質(zhì)為變壓器油（英語(yǔ)：transformer oil），其主要成分為烷烴、環(huán)烷烴、芳香烴等化合物。變壓器油比熱容較大，它吸收熱量體積膨脹上升，在管中形成循環(huán)，再通過(guò)散熱裝置將熱量散發(fā)到空氣中。有的變壓器利用氣態(tài)物質(zhì)（如六氟化硫）作為冷卻劑。由于導(dǎo)熱能力的限制，氣體冷卻劑一般應(yīng)用于小容量變壓器。關(guān)于變壓器油，絕大多數(shù)采用的是礦物油, 極少數(shù)的變壓器采用的是植物油。礦物油泄露可能會(huì)對(duì)環(huán)境造成污染，而植物油污染程度就會(huì)少很多。而且植物油的閃點(diǎn)要比礦物油的高。所以，在將來(lái)，植物油可能會(huì)取代礦物油。及時(shí)消除故障和補(bǔ)充油，確保油位保持在油標(biāo)1/4-3/4處對(duì)于變壓器保持穩(wěn)定是非常有必要的。</p><div

變壓器是應(yīng)用，常見(jiàn)的電力設(shè)備之一。我們都知道變壓器是一種能將某一種電壓、電流、相數(shù)的交流電能轉(zhuǎn)變成另一種電壓、電流、相數(shù)的交流電能的電器。在生產(chǎn)和生活中，經(jīng)常會(huì)用到各種高低不同的電壓，比如工廠中常用的三相異步電動(dòng)機(jī)的額定電壓是380V或220V；照明電路中要用220V；機(jī)床照明、行燈等只需要36V、24V，甚至更低的電壓。這就需要使用變壓器把同一交流電壓變換成頻率相同的不同等級(jí)的電壓，來(lái)滿足不同的使用要求。變壓器不僅能用于改變電壓，還可以用來(lái)改變電流（如變流器、大電流發(fā)生器等）、改變相位（如改變線圈的連接方法來(lái)改變變壓器的極性或組別）、變換阻抗（電子線路中的輸入、輸出變壓器）等。單相變壓器工作原理變壓器的基本工作原理是電磁感應(yīng)原理。上圖所示為一個(gè)簡(jiǎn)單的單相變壓器，其基本結(jié)構(gòu)是在閉合的鐵芯上繞有兩個(gè)匝數(shù)不等的繞組（又稱線圈），繞組之間、鐵芯和繞組之間均相互絕緣，鐵芯由硅鋼片疊成?，F(xiàn)將匝數(shù)為W1的繞組與電源相連，稱該繞組為原繞組或初級(jí)繞組，匝數(shù)為W2的繞組通過(guò)開(kāi)關(guān)K與負(fù)載相連，稱為副繞組或次級(jí)繞組。當(dāng)接通電源，把交流電壓U1加到原繞組上后，交流電流l1流入該繞組，然后產(chǎn)生勵(lì)磁作用。變壓器容量（特性）現(xiàn)場(chǎng)測(cè)試儀是一種非常適合現(xiàn)場(chǎng)準(zhǔn)確測(cè)量變壓器容量和型式的多功能儀表。河南變壓器負(fù)載測(cè)試</p><p
