摘 要：串聯(lián)諧振補(bǔ)償法用于互感器高壓介損測(cè)量是解決現(xiàn)場(chǎng)諸多問題的有效方法。利用電抗與容抗的不同性質(zhì)，串聯(lián)諧振補(bǔ)償法可以大大減小試驗(yàn)電源的容量，給出了測(cè)試實(shí)例，驗(yàn)證了該方法的可行性。在現(xiàn)場(chǎng)使用串聯(lián)諧振補(bǔ)償法進(jìn)行測(cè)量要根據(jù)被測(cè)設(shè)備情況合理選擇儀器設(shè)備和電抗器臺(tái)數(shù)，使其滿足試驗(yàn)回路的要求。

Abstract: The connection in series resonance opposition method used to measure high-voltage mutual inductor dielectric loss is an available approach to solve many onsite problems. The different properties between reactance and capacitive reactance were used,so that the connection in series resonance opposition method could reduce the capacity of testing power supply. Experiments verified the feasibility of this method. According to the situation of measured equipment, the onsite connection in series resonance opposition method needed reasonable selection of apparatus and the number of reactors to meet the requirements of testing circuits.
Key words: mutual inductor; high-voltage mutual inductor dielectric loss; connection in series resonance opposition method
