電弧光保護(hù)系統(tǒng)具備傳統(tǒng)低壓保護(hù)裝置的許多功能，并能夠記錄故障事件和波形，從而為故障的分析提供重要的基礎(chǔ)數(shù)據(jù)。電弧光保護(hù)是一種快速可靠的**母線保護(hù)系統(tǒng)，采用檢測弧光和過流雙判據(jù)原理，具有原理簡單、動(dòng)作可靠迅速、對(duì)變電站一次設(shè)備無特殊要求、適應(yīng)于各種運(yùn)行方式、且在各種運(yùn)行方式下保護(hù)不需要切換等優(yōu)點(diǎn)，為目前發(fā)電廠、變電站、工業(yè)及商業(yè)配電系統(tǒng)母線保護(hù)理想的解決方案。 </p> <p> <br /> </p> <p> 什么是弧光放電？ </p> <p> <br /> </p> <p> 當(dāng)兩電極間電壓升高時(shí)，電極**近處空氣中的正負(fù)離子被電場加速，移動(dòng)的過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> <br /> </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> <br /> </p> <p> 電弧光是怎樣形成的 </p> <p> <br /> </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長的電弧只需20V電壓。也就是說只要先接觸，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> <p> <br />
