國產(chǎn)的弧光保護比進(jìn)口的更適用，國產(chǎn)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(jìn)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(chǎn)品實質(zhì)上是一樣的，面板不同而已。 </p> <p> 目前南京、保定的生產(chǎn)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(jìn)口產(chǎn)品的結(jié)構(gòu)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(shè)備的可靠性。zhidao </p> <p> 弧光保護的技術(shù)發(fā)源地在芬蘭。ABB的REA系列，Vamp的321,221系列，在國內(nèi)都有比較多的應(yīng)用，還有Arcteq、UTU 也都有較成熟的弧光保護產(chǎn)品。 </p> <p> 電弧是放電過程中發(fā)生的一種現(xiàn)象，當(dāng)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(dāng)適當(dāng)?shù)臈l件出現(xiàn)時，一個攜帶著電流的等離子產(chǎn)生，直到電源側(cè)的保護設(shè)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(xué)和物理特性發(fā)生改變時，它可能變成通電的導(dǎo)體。保定弧光保護怎么看高性能弧光保護裝置，廠家直銷。</p><div

***種方法(采用壓力傳感器作為電弧光探測單元) </p> <p> 壓力波是裝置內(nèi)出現(xiàn)電弧***的效應(yīng)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(dāng)內(nèi)部的壓力達(dá)到設(shè)定值時，電弧監(jiān)測裝置發(fā)出動作指令，控制開關(guān)器件動作。但是要預(yù)先確定電弧在柜內(nèi)產(chǎn)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) </p> <p> 弧光監(jiān)測器的操作邏輯如下:電弧現(xiàn)象會產(chǎn)生強烈的光輻射，因此柜體內(nèi)出現(xiàn)的弧光可以被弧光傳感器探測到。當(dāng)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。這種方法的探測反應(yīng)時間*為1毫秒。 </p><p> 電弧光保護目的是在發(fā)生電弧故障時，通過限制電弧燃燒時間來保護附近工作人員及設(shè)備。電弧保護首先必須檢測故障電弧，然后才能切斷流過的故障電流。在中低開關(guān)柜內(nèi)部故障保護中，一般是通過跳開斷路器來切除故障使故障電弧熄滅。電弧燃燒時伴隨著光、聲及電磁波形式的輻射。通過分析可見光、聲波、紅外線或無線電頻率的輻射可以檢測到電弧的存在，甚至連由電弧產(chǎn)生的壓力波也已經(jīng)用來檢測它的存在。然而，*****使用的方法還是通過檢測可見光來實現(xiàn)。 </p> <p>
