絕緣電阻測量儀是一種常用的測量儀器，主要用于測量大型變壓器、互感器、發(fā)電機(jī)、高壓電動(dòng)機(jī)、電力電容、電力電纜、避雷器等設(shè)備的絕緣電阻。***小編主要來介紹一下絕緣電阻測量儀的測量步驟，希望可以幫助用戶更好的應(yīng)用產(chǎn)品。測試儀在工作時(shí)，自身產(chǎn)生高電壓，而測量對象又是電氣設(shè)備，所以必須正確使用，否則就會(huì)造成人身或設(shè)備事故。在使用絕緣電阻測量儀前，首先要做好以下各種準(zhǔn)備工作： 1、測量前必須將被測設(shè)備電源切斷，并對地短路放電，決不允許設(shè)備帶電進(jìn)行測量，以保證人身和設(shè)備的安全。 2、對可能感應(yīng)出高電壓的設(shè)備，必須消除這種可能性后才能進(jìn)行測量。 3、被測物表面要清潔，減少接觸電阻，確保測量結(jié)果的正確性。 </p><p> 絕緣電阻測試儀特點(diǎn) </p> <p> 1、電阻量程范圍可自動(dòng)轉(zhuǎn)換，并有相應(yīng)的指示。 </p> <p> 2、兩種方式同步顯示絕緣阻值。機(jī)械指針采用超薄型張絲結(jié)構(gòu)抗震能力強(qiáng)。機(jī)械指針的采用可容易觀察絕緣電阻的變化范圍，點(diǎn)陣液晶屏的采用可指導(dǎo)用戶操作儀表并可精確得出測量結(jié)果。 </p> <p> 3、機(jī)械表頭與液晶屏合二為一。雙刻度顯示，量程自動(dòng)轉(zhuǎn)換。彩色刻度易于讀識。 </p> <p> 4、采用嵌入式工業(yè)單片機(jī)和實(shí)時(shí)操作軟件系統(tǒng)。自動(dòng)化程度高、抗干擾能力強(qiáng)，儀器可自動(dòng)計(jì)算吸收比和極化指數(shù)，無須人工干預(yù)。 </p> <p> 5、操作界面友好，各種測量結(jié)果具有防掉電功能，可連續(xù)存儲20次的測量結(jié)果。 </p> <p> 6、儀表產(chǎn)生高壓時(shí)，有提示音輸出。 </p> <p> 7、內(nèi)置殘留高壓放電電路，測試完畢可自動(dòng)放掉被測設(shè)備上的殘留高壓。 </p> <p> 8、交直流兩用，配置可充電池和交流適配器。 </p> <p> 9、儀表采用便攜式設(shè)計(jì)，便于野外操作。怎么選絕緣電阻測試儀型號規(guī)格。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="寧夏絕緣電阻測試儀價(jià)格,絕緣電阻測試儀"

500伏以下的電氣設(shè)備選用500~1000伏的兆歐表；瓷瓶、母線、刀閘應(yīng)選用2500伏以上的兆歐表。數(shù)字兆歐表測量范圍的選擇原則是：要使測量范圍適應(yīng)被測絕緣電阻的數(shù)值免讀數(shù)時(shí)產(chǎn)生較大的誤差。如有些兆歐表的讀數(shù)不是從零開始，而是從1兆歐或2兆歐開始。這種表就不適宜用于測定處在潮濕環(huán)境中的低壓電氣設(shè)備的絕緣電阻。因?yàn)檫@種設(shè)備的絕緣電阻有有可能小于1兆歐，使儀表得不到讀數(shù)，容易誤認(rèn)為絕緣電阻為零，而得出錯(cuò)誤結(jié)論
