style="text-indent:25px"> 超高頻檢測法變壓器在發(fā)作局部放電時都會呈現(xiàn)正負(fù)電荷中和的現(xiàn)象，而且隨同這一現(xiàn)象都會構(gòu)成一個陡的電流脈沖向四周輻射電磁波。該辦法首要是經(jīng)過對變壓器內(nèi)部產(chǎn)生局部放電時所發(fā)射的超高頻電磁波中止接納，從而抵達(dá)對局部放電的定位和檢測。這種檢測辦法的首要優(yōu)點是丈量頻率比擬高、檢測頻率范圍可以調(diào)理、抗電磁波干擾性能強、靈活度較高。射頻檢測法該辦法首要是經(jīng)過應(yīng)用電流互感線圈從變壓器的中性點中止丈量獲取信號，丈量的信號頻率通常能夠抵達(dá)3萬kHz，從很大水平進(jìn)步了局部放電的丈量頻率。首要優(yōu)點是射頻檢測體系裝置便利，檢測設(shè)備不會改動變壓器的運轉(zhuǎn)辦法；其缺點是由于射頻檢測只能對單一的信號中止分辯，無法精確的判別三相變壓器局部放電信號的總和，因而，不適合三相變壓器的局部放電檢測。輔助絕緣安全工器具：是指絕緣強度不能承受工作電壓的作用。安徽低壓電器實驗</p><p
