接地故障電弧起火：由于“接地故障發(fā)生的幾率遠(yuǎn)大于帶電導(dǎo)體間的短路”，河北弧光保護(hù)如何選型，所以“接地故障電弧引起的火災(zāi)遠(yuǎn)多于帶電導(dǎo)體間的電弧火災(zāi)”。這是因?yàn)椤霸陔姎饩€路施工中，穿鋼管拉電線時(shí)帶電導(dǎo)體絕緣外皮之間并無因相對運(yùn)動而產(chǎn)生的摩擦，但帶電導(dǎo)體絕緣外皮與鋼管間的摩擦卻使絕緣摩薄或受損，河北弧光保護(hù)如何選型。另外，發(fā)生雷擊時(shí)地面上出現(xiàn)瞬變電磁場，它對電氣線路將感應(yīng)瞬態(tài)過電壓”，此時(shí)“芯線上感應(yīng)的瞬態(tài)過電壓是基本相同的，而電纜梯架則因接地而為地電壓”，河北弧光保護(hù)如何選型，所以，芯線對地的電位差較大。從摩損和電位差大兩方面分析，接地故障電弧起火率自然偏高。 </p> <p> 爬電起火：爬電是指電弧不是建立在空氣間隙中的電弧，而是出現(xiàn)在設(shè)備絕緣表面上的電弧。例如電源插頭的絕緣表面上的一個(gè)或多個(gè)相線插腳和PE線插腳，它們之間的絕緣表面可能發(fā)生爬電。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

14598.302-2016《弧光保護(hù)裝置技術(shù)要求》已于2016年9月1日正式實(shí)施。 </p> <p> 本標(biāo)準(zhǔn)規(guī)定了弧光保護(hù)裝置的技術(shù)要求、試驗(yàn)方法、檢驗(yàn)規(guī)則、標(biāo)志、標(biāo)簽和包裝、運(yùn)輸、貯存等。 </p> <p> 標(biāo)準(zhǔn)適用于弧光保護(hù)裝置及其接口設(shè)備，作為弧光保護(hù)產(chǎn)品設(shè)計(jì)、制造、試驗(yàn)和應(yīng)用的依據(jù)。 </p> <p> GB/T 14598.302-2016《弧光保護(hù)裝置技術(shù)要求》國家標(biāo)準(zhǔn)的發(fā)布實(shí)施，完善了我國國家標(biāo)準(zhǔn)體系，為廣大弧光保護(hù)制造廠家、電力用戶及檢測機(jī)構(gòu)提供統(tǒng)一的標(biāo)準(zhǔn)依據(jù)，同時(shí)也更有助于提升弧光保護(hù)產(chǎn)品的質(zhì)量、規(guī)范弧光保護(hù)裝置的產(chǎn)品市場，提高企業(yè)的生產(chǎn)效率，形成產(chǎn)業(yè)優(yōu)勢，從而提高弧光保護(hù)裝置產(chǎn)品在國內(nèi)乃至國際市場方面的競爭力。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河北弧光保護(hù)如何選型" src="https://tyunfile.71360.com/UploadFile/keaton/637255090210458984/175496.jpg"></div><p> 1.1 電弧光產(chǎn)生的原因 </p> <p> 引起開關(guān)柜弧光短路故障的原因很多，主要有：絕緣故障、載流回路不良、外來物體的進(jìn)入、人為操作錯(cuò)誤、系統(tǒng)改變或故障等。 </p> <p> 1.2 電弧光的能量 </p> <p> 開關(guān)柜發(fā)生內(nèi)部弧光故障產(chǎn)生的短路功率可高達(dá)8~60 MW，所產(chǎn)生的能量與電弧的燃燒時(shí)間、短路電流的平方值、柜體幾何尺寸以及所使用的材料等因素有關(guān)，其中**主要的因素是短路故障電流及電弧燃燒的時(shí)間，電弧能量與有關(guān)電弧燃燒的時(shí)間的關(guān)系如圖所示。從圖中可以看出，電弧燃燒持續(xù)時(shí)間超過100 ms ，所釋放的能量開始急劇增加，接著各種故障效應(yīng)對開關(guān)設(shè)備的電纜、銅排以及鋼材造成嚴(yán)重?fù)p壞. </p> <p> <br /> </p></p><br /><p>文章來源地址: http://m.cdcfah.com/cp/365066.html</p></div></div></div></div></div><div id="0ht89tk"
