在鐵芯中產(chǎn)生的交變磁通不僅穿過原繞組，同時(shí)也穿過副繞組，它分別在兩個(gè)繞組中引起感應(yīng)電動(dòng)勢(shì)。這時(shí)如果開關(guān)K合上，副繞組與外電路的負(fù)載相連通，便有電流I2流出，負(fù)載端電壓即為U2，于是輸出電能。對(duì)變壓器的作用和工作原理有了一定的了解后，我們來(lái)討論一下變壓器分接開關(guān)應(yīng)該如何調(diào)整？運(yùn)行中系統(tǒng)電壓過高或過低，影響設(shè)備的正常運(yùn)行時(shí)，需要對(duì)變壓器分接開關(guān)進(jìn)行適當(dāng)?shù)卣{(diào)整，以保持變壓器二次側(cè)電壓的正常。10kV變壓器的分接開關(guān)有三個(gè)位置，調(diào)壓范圍為±5%，當(dāng)系統(tǒng)的電壓變化不超過額定電壓的±5%時(shí)，可以通過調(diào)節(jié)變壓器分接開關(guān)的位置來(lái)解決電壓過高或過低的問題。無(wú)載調(diào)壓的配電變壓器，分接開關(guān)有三擋，即Ⅰ擋時(shí)，為10500/400V；Ⅱ擋時(shí)，為10000/400V；Ⅲ擋時(shí)，為9500/400V。當(dāng)系統(tǒng)電壓高，超過額定電壓時(shí)，變壓器二次側(cè)母線電壓高，需要將變壓器分接開關(guān)調(diào)到Ⅰ擋位置。如果系統(tǒng)電壓低，達(dá)不到額定電壓時(shí)，變壓器二次側(cè)電壓低，就需要將變壓器分接開關(guān)調(diào)至Ⅲ擋位置。即所謂的“高往高處調(diào)，低往低處調(diào)”。但是，變壓器分接開關(guān)的調(diào)整要注意相對(duì)地穩(wěn)定，不可頻繁調(diào)整，否則將影響變壓器的運(yùn)行壽命。云南試驗(yàn)用變壓器變壓器發(fā)生不同性質(zhì)的故障，聲音會(huì)發(fā)生變化。這時(shí)應(yīng)根據(jù)現(xiàn)場(chǎng)情采取措施，查找故障原因。</p><div

變壓器是應(yīng)用，常見的電力設(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。現(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的繞組通過開關(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。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
