帶電導(dǎo)體間的電弧性短路起火：短路起火時(shí)有兩種可能，其一是兩導(dǎo)體（如相線與中性線）接觸時(shí)因短路電流產(chǎn)生的高溫，使接觸點(diǎn)金屬熔化，之后金屬熔化成團(tuán)收縮而脫離接觸的過(guò)程，這種情況下可能建立電弧。又如線路絕緣水平嚴(yán)重下降，雷電產(chǎn)生的瞬態(tài)過(guò)電壓或電網(wǎng)故障產(chǎn)生的暫態(tài)過(guò)電壓都可能擊穿劣化的線路絕緣而建立電弧。電弧性短路的起火危險(xiǎn)遠(yuǎn)大于上述金屬性短路的起火危險(xiǎn)。

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”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)椤半姎饩€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(wú)因相對(duì)運(yùn)動(dòng)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。另外，發(fā)生雷擊時(shí)地面上出現(xiàn)瞬變電磁場(chǎng)，對(duì)電氣線路將感應(yīng)瞬態(tài)過(guò)電壓”此時(shí)“芯線上感應(yīng)的瞬態(tài)過(guò)電壓是基本相同的而電纜梯架則因接地而為地電壓”所以，芯線對(duì)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。孝感弧光保護(hù)電源耐用型弧光保護(hù)，廠家直銷，歡迎咨詢。</p><div

廠用/配電中壓開關(guān)柜為全廠輔機(jī)/供電系統(tǒng)的供電樞紐。在發(fā)生內(nèi)部故障時(shí)，是否能迅速地切除故障，對(duì)全廠/配電系統(tǒng)的安全運(yùn)行至關(guān)重要。但是，按目前的保護(hù)方案，存在以下幾個(gè)問(wèn)題： </p> <p> ① 中壓母線尚沒(méi)有配置任何專門的保護(hù); 而是由進(jìn)線開關(guān)的相關(guān)后備保護(hù)來(lái)兼顧的; </p> <p> ② 進(jìn)線開關(guān)與出線開關(guān)的保護(hù)需要相互配合:一般速斷保護(hù)延時(shí)的級(jí)差至少為300ms，甚至500ms ; </p> <p> ③ 過(guò)流保護(hù)的配合級(jí)差更是長(zhǎng)達(dá)1 – 2秒。 </p> <p> 所以，廠用/配電系統(tǒng)中壓母線上所發(fā)生的任何故障都至少要延時(shí)切除。換句話說(shuō)，現(xiàn)有的廠用中壓母線能在**早時(shí)間切除故障的保護(hù)還是個(gè)空白?？墒?，我們只要稍加注意，就會(huì)不難發(fā)現(xiàn)不論是中壓開關(guān)母線的上游還是下游的諸多電氣設(shè)備無(wú)一沒(méi)有配有快速保護(hù)。相比之下，我們恐怕很難有充分的理由來(lái)說(shuō)明，中壓母線的安全性可靠性應(yīng)該受到這樣的懈怠。鑒于中壓母線的重要地位，任何故障的延時(shí)切除，都是我們極為不愿意看到的狀況。因?yàn)殚_關(guān)柜內(nèi)的各種故障，其短路電流所產(chǎn)生的電弧及其大量的高溫，使柜內(nèi)氣體急劇膨脹，可在極短的時(shí)間內(nèi)達(dá)到頂峰，嚴(yán)重危及人身和設(shè)備安全。 </p> <p> <br /> </p><p> 主動(dòng)保護(hù)有以下兩種常見(jiàn)的可行的方法：1通過(guò)壓力傳感器進(jìn)行監(jiān)測(cè);2通過(guò)弧光傳感器進(jìn)行監(jiān)測(cè) </p> <p> <br /> </p> <p>

當(dāng)兩電極間電壓升高時(shí)，在電極**近處空氣中的正負(fù)離子被電場(chǎng)加速，在移動(dòng)的過(guò)程中與其它空氣分子碰撞產(chǎn)生新的離子，這種離子大量增加的現(xiàn)象稱為“電離”。空氣被電離的同時(shí)，溫度隨之急劇上升產(chǎn)生電弧，這種放電稱為弧光放電。弧光放電一般不需要很高的電壓，屬于低電壓大電流放電。 </p> <p> 弧光放電產(chǎn)生的條件是小間隙和大電流，如果增加間隙或減小電流，電弧將會(huì)消失。 </p> <p> <p> 電弧光是怎樣形成的？ </p> <p> 電弧性短路起火：如將兩電極接觸后再拉開建立了電弧，則維持此10mm 長(zhǎng)的電弧只需20V 的電壓。也就是說(shuō)只要先接觸，之后又分開，很可能產(chǎn)生局部溫度很高的電弧而成為起火源。按電弧發(fā)生的不同部分可分為帶電導(dǎo)體間的電弧、帶電導(dǎo)體與地之間的電弧和絕緣表面的爬電。 </p> 大同高壓弧光保護(hù)</p><p
