在鐵芯中產(chǎn)生的交變磁通不僅穿過原繞組，同時也穿過副繞組，它分別在兩個繞組中引起感應(yīng)電動勢。這時如果開關(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。對變壓器的作用和工作原理有了一定的了解后，我們來討論一下變壓器分接開關(guān)應(yīng)該如何調(diào)整？運行中系統(tǒng)電壓過高或過低，影響設(shè)備的正常運行時，需要對變壓器分接開關(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，可以通過調(diào)節(jié)變壓器分接開關(guān)的位置來解決電壓過高或過低的問題。無載調(diào)壓的配電變壓器，分接開關(guān)有三擋，即Ⅰ擋時，為10500/400V；Ⅱ擋時，為10000/400V；Ⅲ擋時，為9500/400V。當(dāng)系統(tǒng)電壓高，超過額定電壓時，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，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)整要注意相對地穩(wěn)定，不可頻繁調(diào)整，否則將影響變壓器的運行壽命。變壓器測試儀器是用于變壓器容量、空載、負(fù)載等特性參數(shù)測量的高精密儀器。湖北交流高壓試驗電子變壓器</p><p
