答：強行油(you)循(xun)環往復低(di)壓(ya)變壓(ya)器(qi)(qi)(qi)(qi)提出(chu)“冷(leng)(leng)卻器(qi)(qi)(qi)(qi)全停”信號(hao)，值班人(ren)員應(ying)立即檢(jian)查斷電原(yuan)因，盡快恢復冷(leng)(leng)卻裝置的(de)運(yun)(yun)行。對沒有備用冷(leng)(leng)卻器(qi)(qi)(qi)(qi)的(de)變壓(ya)器(qi)(qi)(qi)(qi)，值班人(ren)員應(ying)向當值調度員申(shen)請(qing)降(jiang)低(di)負荷，否則應(ying)申(shen)請(qing)將變壓(ya)器(qi)(qi)(qi)(qi)退出(chu)運(yun)(yun)行，防止變壓(ya)器(qi)(qi)(qi)(qi)運(yun)(yun)行超過規定(ding)的(de)無(wu)冷(leng)(leng)卻運(yun)(yun)行時(shi)間，造成過熱損壞。在變壓(ya)器(qi)(qi)(qi)(qi)發(fa)出(chu)“冷(leng)(leng)卻器(qi)(qi)(qi)(qi)備用投入”信號(hao)時(shi)，應(ying)檢(jian)查故障(zhang)冷(leng)(leng)卻器(qi)(qi)(qi)(qi)的(de)故障(zhang)原(yuan)因，盡快修復。
