電力設(shè)備絕緣的交接和預(yù)防性實驗是檢查、審定設(shè)備的安康情況，避免設(shè)備在運轉(zhuǎn)中發(fā)作損壞的重要措施。按電力部DL/T596《電力設(shè)備預(yù)防性實驗規(guī)程》及GB 50150《電氣安裝裝置工程電氣設(shè)備交接實驗規(guī)范》的根本肉體，分離大唐集團公司的詳細(xì)狀況，特制定本規(guī)程。 2 本規(guī)程所規(guī)則的各項實驗規(guī)范，是電力設(shè)備絕緣監(jiān)控工作的根本請求，也是電力設(shè)備全過程管理工作的重要組成局部。在設(shè)備的驗收、維護、檢修工作中必需堅持以預(yù)防為主，積極地對設(shè)備停止維護，使其能長期平安、經(jīng)濟運轉(zhuǎn)。 3 對實驗結(jié)果必需停止地、歷史地綜合剖析和比擬，即要對照歷次實驗結(jié)果，也要對照同類設(shè)備或不同相別的實驗結(jié)果，依據(jù)變化規(guī)律和趨向，經(jīng)***剖析后作出判別。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

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3 萬kHz，從很大水平進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。</p><div style="width:100%;text-align: center;"><img
