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(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(shí)，電弧監(jiān)測裝置發(fā)出動(dòng)作指令，控制開關(guān)器件動(dòng)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，煙臺弧光保護(hù)模塊。 </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(huì)產(chǎn)生強(qiáng)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(huì)發(fā)出動(dòng)作信號給斷路器。這種方法的探測反應(yīng)時(shí)間*為1毫秒，煙臺弧光保護(hù)模塊。弧光保護(hù)裝置，煙臺弧光保護(hù)模塊，弧光保護(hù)傳感器專業(yè)生產(chǎn)，歡迎來電咨詢。煙臺弧光保護(hù)模塊</p><div

在110KV變電站的中低壓母線一般不配置母線保護(hù)，近年來為了有效控制變電站中低壓母線開關(guān)設(shè)備損壞及母線和斷路器故障引起主變壓器損壞的發(fā)生，越來越多的變電站中低壓開關(guān)柜配置電弧光保護(hù)。通過弧光保護(hù)裝置可以快速地切除故障點(diǎn)，保證系統(tǒng)的安全穩(wěn)定運(yùn)行。 </p> <p> 應(yīng)用范圍 </p> <p> 適用于電力開關(guān)柜中，引入電弧光保護(hù)裝置，可以捕捉到電氣弧光，并快速地切除故障點(diǎn)，保證電力系統(tǒng)的安全穩(wěn)定運(yùn)行。 </p> <p> 主要特點(diǎn) </p> <p> 1、動(dòng)作迅速可靠 </p> <p> 采用了可靠的快速算法，可以在短時(shí)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(shí)間間隔優(yōu)于10ms，確保開關(guān)柜內(nèi)設(shè)備的弧光在75ms以內(nèi)切除。 </p> <p> 2、全數(shù)字化設(shè)計(jì) </p> <p> 本裝置采用全數(shù)字化設(shè)計(jì)，配置靈活，動(dòng)作精度高，而且排除了由于旋鈕或其他機(jī)械設(shè)計(jì)導(dǎo)致的誤差***。 </p> <p> 3、保護(hù)原理簡單、合理 </p> <p> 根據(jù)弧光產(chǎn)生時(shí)的特點(diǎn)，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(dòng)作的準(zhǔn)確性。 </p> <p> 4、強(qiáng)大的電氣性能 </p> <p> 弧光探頭設(shè)計(jì)、連接線等全部采用耐高溫、阻燃的高分子材料，具有強(qiáng)大的電氣隔離效果。裝置完全 </p><p> 電弧光保護(hù)系統(tǒng)作用：電弧光保護(hù)系統(tǒng)具有非?？斓膭?dòng)作速度，對開關(guān)柜各單元室的總故障清掉時(shí)間可控制在100ms以內(nèi)。因此，在發(fā)生弧光故障、柜內(nèi)壓力和溫度急劇增加以前，電弧光保護(hù)系統(tǒng)就可以發(fā)出跳閘指令切除供給的短路電流，使設(shè)備損壞及人員傷害的損失減到**小。 </p> <p> 對于中低壓開關(guān)柜來講，以**快的速度切除故障意味著比較大限度地限制電弧燃燒釋放的能量，其益處是：1）保護(hù)附近工作人員免受電弧故障效應(yīng)的傷害；2）開關(guān)柜內(nèi)部部件的限制到**??；3）很大減少開關(guān)設(shè)備損壞的維修費(fèi)用；4）比較大限度地減少用戶停電時(shí)間，可盡快恢復(fù)生產(chǎn)；5）對于使用年限很長需要進(jìn)行改造的開關(guān)柜，采用電弧光保護(hù)可有效延長其使用壽命，從而減少對開關(guān)設(shè)備的投資費(fèi)用。 </p> <p> 電弧光保護(hù)作為中低壓母線保護(hù)，對配電系統(tǒng)還將提供以下益處：1）保護(hù)昂貴的主變壓器或廠用變壓器免受巨大的短路電流沖擊而損壞；2）防止波及站用直流系統(tǒng)，避免故障擴(kuò)大而造成經(jīng)濟(jì)損失。母線弧光保護(hù)，歡迎來電咨詢。</p><div style="width:100%;text-align:

廠用/配電中壓開關(guān)柜為全廠輔機(jī)/供電系統(tǒng)的供電樞紐。在發(fā)生內(nèi)部故障時(shí)，是否能迅速地切除故障，對全廠/配電系統(tǒng)的安全運(yùn)行至關(guān)重要。但是，按目前的保護(hù)方案，存在以下幾個(gè)問題： </p> <p> ① 中壓母線尚沒有配置任何專門的保護(hù); 而是由進(jìn)線開關(guān)的相關(guān)后備保護(hù)來兼顧的; </p> <p> ② 進(jìn)線開關(guān)與出線開關(guān)的保護(hù)需要相互配合:一般速斷保護(hù)延時(shí)的級差至少為300ms，甚至500ms ; </p> <p> ③ 過流保護(hù)的配合級差更是長達(dá)1 – 2秒。 </p> <p> 所以，廠用/配電系統(tǒng)中壓母線上所發(fā)生的任何故障都至少要延時(shí)切除。換句話說，現(xiàn)有的廠用中壓母線能在**早時(shí)間切除故障的保護(hù)還是個(gè)空白。可是，我們只要稍加注意，就會(huì)不難發(fā)現(xiàn)不論是中壓開關(guān)母線的上游還是下游的諸多電氣設(shè)備無一沒有配有快速保護(hù)。相比之下，我們恐怕很難有充分的理由來說明，中壓母線的安全性可靠性應(yīng)該受到這樣的懈怠。鑒于中壓母線的重要地位，任何故障的延時(shí)切除，都是我們極為不愿意看到的狀況。因?yàn)殚_關(guān)柜內(nèi)的各種故障，其短路電流所產(chǎn)生的電弧及其大量的高溫，使柜內(nèi)氣體急劇膨脹，可在極短的時(shí)間內(nèi)達(dá)到頂峰，嚴(yán)重危及人身和設(shè)備安全。
