本發明的使用方法和工(gong)作原(yuan)理是：

如(ru)圖5所示，首先(xian)測(ce)(ce)量每一只電(dian)容(rong)器(qi)的(de)電(dian)容(rong)值，整(zheng)(zheng)個電(dian)容(rong)器(qi)塔測(ce)(ce)完后生成一個數(shu)據(ju)文件，軟件根據(ju)優化算(suan)法調(diao)整(zheng)(zheng)電(dian)容(rong)器(qi)位置(zhi)，利用不平衡電(dian)流(liu)計算(suan)公式，計算(suan)出不平衡電(dian)流(liu)的(de)理論值，如(ru)果該(gai)值小于不平衡電(dian)流(liu)報警值，則輸出調(diao)整(zheng)(zheng)方案(an)。檢修人員(yuan)根據(ju)調(diao)整(zheng)(zheng)方案(an)交換電(dian)容(rong)器(qi)位置(zhi)，然后再(zai)實測(ce)(ce)不平衡電(dian)流(liu)值，如(ru)果實測(ce)(ce)值滿足要(yao)求，則調(diao)整(zheng)(zheng)結束。

傳統的(de)測(ce)(ce)試方法采(cai)(cai)用(yong)調壓器加400v工頻(pin)(pin)電壓于電容(rong)器塔，本發明(ming)采(cai)(cai)用(yong)36v高(gao)頻(pin)(pin)電壓測(ce)(ce)試不平(ping)衡電流，既(ji)提高(gao)了測(ce)(ce)試安全性，而且大(da)大(da)減小了工頻(pin)(pin)磁場對測(ce)(ce)試結果的(de)影響，大(da)大(da)提高(gao)測(ce)(ce)試精度(du)。電容(rong)器塔不平(ping)衡電流配(pei)平(ping)的(de)傳統方法完全采(cai)(cai)用(yong)人為估算的(de)方法，配(pei)平(ping)過程需(xu)要(yao)反復進行，費時(shi)、費力且無法達到最理想化的(de)最小值。本發明(ming)一(yi)次(ci)調整即可達到最小不平(ping)衡電流，大(da)大(da)減少了換流站(zhan)停運時(shi)間。
