適用于電力開關柜中，引入電弧光保護裝置，可以捕捉到電氣弧光，并快速地切除故障點，保證電力系統(tǒng)的安全穩(wěn)定運行。 </p> <p> 主要特點 </p> <p> 1、動作迅速可靠 </p> <p> 采用了可靠的快速算法，可以在短時間內(nèi)判斷弧光變化信號和電流變化信號并迅速出口，從發(fā)現(xiàn)故障到出口跳閘時間間隔優(yōu)于10ms，確保開關柜內(nèi)設備的弧光在75ms以內(nèi)切除。 </p> <p> 2、全數(shù)字化設計 </p> <p> 本裝置采用全數(shù)字化設計，配置靈活，動作精度高，而且排除了由于旋鈕或其他機械設計導致的誤差***。 </p> <p> 3、保護原理簡單、合理 </p> <p> 根據(jù)弧光產(chǎn)生時的特點，裝置采用弧光和電流雙重判據(jù)，判據(jù)簡單且可以有效的保證動作的準確性。 </p> <p> 4、強大的電氣性能 </p> <p> 弧光探頭設計、連接線等全部采用耐高溫、阻燃的高分子材料，具有強大的電氣隔離效果。裝置完全 </p><p> 一旦發(fā)生電弧光故障,這一裝置可以迅速可靠動作,切除故障電源,準確定位故障點。對于變電所、大型企業(yè)用電的各種運行方式,可以具體情況和客戶需要靈活配置,適應性強。JD9900B電弧光保護綜合測控系統(tǒng)是我公司根據(jù)市場需要開發(fā)的新一代產(chǎn)品,系統(tǒng)動作準確,反應靈敏,可靠性高。JD9900B采用分布式模式設計,適合作為中低壓母線保護,具備靈活的組**性。其中饋線保護單元可**形成**小化保護系統(tǒng),單獨保護饋線以減小***停電范圍。饋線單元也可運行于集中監(jiān)控模式,通過某一主單元與調度通信。JD9900B 電弧光保護采用檢測弧光和電流為輸入量,可單獨做為過流保護,純弧光保護,及弧光與過流雙判據(jù)保護。本系統(tǒng)具有原理簡單、動作可靠迅速、對一次設備無特殊要求、適應于各種運行方式的優(yōu)點。JD9900B是發(fā)電廠、變電站、工業(yè)及商業(yè)配電系統(tǒng) 380V~35kV 中低壓母線保護的理想解決方案。使用 JD9900B電弧光保護,可以快速切除故障,從根本上限制故障電弧延續(xù)時間,消除其對人身的危害,比較大限度地降低弧光對電氣設備的損壞程度,避免主變壓器等設備長時間遭受短路電流的沖擊而損壞,阻斷故障的擴大。弧光保護專業(yè)生產(chǎn)廠家。</p><div style="width:100%;text-align: center;"><img style="max-width:

主配電柜或大型的電氣設備(如變壓器或發(fā)電機)附近短路能量高而且有故障產(chǎn)生時的電壓也很高。 </p> <p> 在柜體內(nèi)形成電弧的過程可分為四個階段: </p> <p> 壓縮階段:電弧占據(jù)了整個空氣空間，由于持續(xù)的釋放能量產(chǎn)生過熱，導致對流和輻射，保留在柜內(nèi)的空氣被加熱，在整個初級階段不同區(qū)域的溫度和壓力值不一樣。 </p> <p> 擴展階段:從這一瞬間開始，內(nèi)部壓力增加，由于過熱的空氣開始流動而形成一個空洞。在這個階段其壓力達到比較大值，并因為熱空氣的釋放而開始減弱。 </p> <p> 發(fā)射階段:由于電弧能量的持續(xù)釋放，幾乎所有的空氣均被一個緩和但恒定的壓力擠壓出去。 </p> <p> 發(fā)熱階段:在驅逐出空氣后，柜內(nèi)的溫度幾乎達到電弧的溫度。***階段就由此開始，直至熄滅。此時，所有金屬和絕緣體在受到產(chǎn)生的氣體、霧和溶蝕物質顆粒的侵蝕后，已融為一體了。 </p> <p> 當電弧出現(xiàn)在非常封閉的設備環(huán)境時，可能不會出現(xiàn)上述某些階段或者只有較少的影響;然而，在電弧的周圍，會形成壓力波、并導致溫度的上升。弧光保護裝置廠家直銷，全國招商。綿陽弧光保護報價</p><p style="text-indent:25px">穩(wěn)定性好，保護功能強大，母線弧光保護，廠家直銷。貴陽高精度弧光保護</p><p> 電弧光保護系統(tǒng)：
