摘 要：擴(kuò)大有載調(diào)容變壓器的適用范圍有利于該產(chǎn)品的推廣應(yīng)用。從可靠性、經(jīng)濟(jì)性兩方面對兩種有載調(diào)容變壓器大小容量組合方案進(jìn)行了對比分析，認(rèn)為小容量下的短路阻抗值不應(yīng)作為大小容量組合的約束條件，應(yīng)根據(jù)變壓器實(shí)際安裝場合的負(fù)荷波動大小按經(jīng)濟(jì)運(yùn)行要求來選擇，采用S13 型節(jié)能型產(chǎn)品，適當(dāng)提高小容量額定值，有利于減少一次性投入，獲得較好的經(jīng)濟(jì)效益和社會效益。
關(guān)鍵詞：有載調(diào)容變壓器；短路阻抗；負(fù)荷波動

Abstract: Expanding the application of on-load capacity regulating transformer is beneficial to the popularization of it. Two kinds of on-load capacity regulating transformers, which were different from the combination of high and low capacity, were carried out comparison and analysis on the reliability and economical efficiency. The short-circuit impedance value under low capacity should not be taken as the constraint condition of combined capacity size, but make a choice according to load fluctuation of transformer practical installation site and economic operation requirement. The S13-type energy-saving products were adopted to raise the low capacity rating appropriately, which is conducive to decrease primary input-cost and can obtain good economic and social benefits.
Key words: on-load capacity regulating; short-circuit impedance; load fluctuation
