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 長的電弧只需20V 的電壓。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> 甘肅母線弧光保護(hù)母線弧光保護(hù)廠家直銷。</p><div style="width:100%;text-align: center;"><img

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 />
