第一種方法（采用壓力傳感器作為電弧光探測單元）壓力波是裝置內出現(xiàn)電弧***的效應之一，它將在電弧出現(xiàn)后的10-15毫秒后出現(xiàn)，可以安裝一些壓力傳感器用于探測壓力峰值。當內部的壓力達到設定值時，電弧監(jiān)測裝置發(fā)出動作指令，控制開關器件動作。但是要預先確定電弧在柜內產生的過壓值并非易事。 </p> <p> 第二種方法（采用光纖傳感器作為電弧光探測單元）弧光監(jiān)測器的操作邏輯如下：電弧現(xiàn)象會產生強烈的光輻射，因此柜體內出現(xiàn)的弧光可以被弧光傳感器探測到，貴陽弧光保護技術。當弧光監(jiān)控系統(tǒng)探測到故障，會發(fā)出動作信號給斷路器，貴陽弧光保護技術。這種方法的探測反應時間*為1毫秒。中低壓弧光保護，貴陽弧光保護技術，專業(yè)提供，歡迎來電咨詢。貴陽弧光保護技術</p><div

國產的弧光保護比進口的更適用，國產的把主控單元、電流單元和copy弧光采集單元集成在一起，安裝方便，可靠性高，進口的分幾個單元主要是為了自己的利益。其實UTU和RIZNER兩個產品實質上是一樣的，面板不同而已。 </p> <p> 目前南京、保定的生產廠家都是采用一體式的裝置，只有早起仿ABB、VAMP、UTU的廠家按照進口產品的結構模式做的，各個單元之間通過電纜連接，人為增加了節(jié)點，反而降低了設備的可靠性。zhidao </p> <p> 弧光保護的技術發(fā)源地在芬蘭。ABB的REA系列，Vamp的321,221系列，在國內都有比較多的應用，還有Arcteq、UTU 也都有較成熟的弧光保護產品。 </p> <p> 電弧是放電過程中發(fā)生的一種現(xiàn)象，當兩點之間的電壓超過其工頻絕緣強度極限時就會發(fā)生。當適當?shù)臈l件出現(xiàn)時，一個攜帶著電流的等離子產生，直到電源側的保護設備斷開才會消失?？諝庠谕ǔl件是很好的絕緣體，但由于溫度的升高或者其他外部因素的作用，其化學和物理特性發(fā)生改變時，它可能變成通電的導體。 </p><p> 電弧光保護電弧光是通過電離的氣體（空氣）在帶電體和地之間或帶電體之間的短路。高能量的電弧光故障表現(xiàn)為電氣。它們釋放了大量的能量，表現(xiàn)為輻射、熱、強光和高壓波的形式。 </p> <p> 電弧光保護裝置主要作用： </p> <p> 1、減少或降低電弧光對于人體的傷害。 </p> <p> 2、減少或降低電弧光短路故障對于設備的損害。 </p> <p> 3、避免變壓器因近距離母線故障造成動穩(wěn)定破壞，延長變壓器的使用壽命。 </p> <p> 4、縮短電弧光故障切除時間，避免波及站內直流系統(tǒng)造成重大損失。 </p> <p> 5、減少因電弧光故障造成設備停運的時間，更快地恢復供電。電弧光保護裝置廠家直銷，歡迎來咨詢。</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 的電壓。也就是說只要先接觸，之后又分開，很可能產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體間的電弧、帶電導體與地之間的電弧和絕緣表面的爬電。 </p> <p> 帶電導體間的電弧性短路起火：短路起火時有兩種可能，其一是兩導體（如相線與中性線）接觸時因短路電流產生的高溫，使接觸點金屬熔化，之后金屬熔化成團收縮而脫離接觸的過程，在這種情況下可能建立電弧?！坝秩缇€路絕緣水平嚴重下降，雷電產生的瞬態(tài)過電壓或電網故障產生的暫態(tài)過電壓都可能擊穿劣化的線路絕緣而建立電弧?！薄半娀⌒远搪返钠鸹鹞ｋU遠大于上述金屬性短路的起火危險。”

而為什么其他母線保護的動作時間那么長，因為“保護配合”。電弧光保護只要滿足“電弧”和“過流”等判據就可立即發(fā)出跳閘指令。而其他母線保護（參考西門子公司7SD和7SJ62綜保裝置）當滿足“過流”判據后還必須等待下級負載的“無過流匯報”后才可以發(fā)出跳閘指令。因為下級負載短路和母線短路都會造成進線開關“過流”，如果下級負載短路應該讓下級負載開關來切除，母線短路則由母線進線開關來切除。電弧光保護猶如手持尚方寶劍，而其他母線保護則就像一個團隊，不敢輕舉妄動。 </p> <p> 總上所述，采用電弧光母線保護可以在現(xiàn)有開關柜的電弧耐受時間標準以內切除弧光短路故障，從而比較大限度地保護了附近工作人員，使開關裝置等配電設備免受損壞，很大減少了設備維修費用及維修故障所需的停電時間，因而具有明顯的經濟效益，為理想的中壓母線保護解決方案。貴陽弧光保護技術</p><p
