電弧光保護(hù)以電流單元為基礎(chǔ)分組，弧光探頭可以整定關(guān)聯(lián)到任意一組電流信號(hào)上。當(dāng)弧光單元把光信號(hào)從弧光傳感器傳輸?shù)交」獗Ｗo(hù)設(shè)備時(shí)，并且同時(shí)電流啟動(dòng)元件動(dòng)作和電弧光保護(hù)動(dòng)作，裝置可選擇弧光信號(hào)動(dòng)作單判據(jù)作為動(dòng)作邏輯判斷。 </p> <p> 當(dāng)檢測(cè)到本身硬件故障時(shí)，發(fā)出告警信號(hào)，同時(shí)閉鎖整套保護(hù)。硬件故障包括：采樣回路故障、RAM出錯(cuò)、定值出錯(cuò)等。 </p> <p> <br /> </p> <p> 端子圖及定義 </p> <p> 主要的端子數(shù)量有：6個(gè)弧光信號(hào)檢測(cè)接口，用于接收來(lái)自弧光傳感器的弧光故障信號(hào)。4個(gè)數(shù)據(jù)通訊接口，2路RS485，1路CAN總線，1路以太網(wǎng)。4路快速跳閘輸出接口，符合IEC255-23繼電器標(biāo)準(zhǔn)。2路報(bào)警出口，其中一路為裝置故障出口。12路電流輸入，檢測(cè)4組三相電流信號(hào)，用于判斷故障電流。

</p> <p> 從弧光保護(hù)設(shè)計(jì)的系統(tǒng)可靠性來(lái)看,變壓器、進(jìn)線、饋線都有主保護(hù),唯獨(dú)母線沒(méi)有**的主保護(hù),我們認(rèn)為母線應(yīng)該增加**主保護(hù)。雖然母線故障出現(xiàn)概率較低,但一旦出現(xiàn)將損失慘重。因此,從技術(shù)、設(shè)計(jì)方面建議配置母線**主保護(hù)弧光保護(hù),以確保操作人員的人身安全及系統(tǒng)的安全、穩(wěn)定運(yùn)行。各種弧光保護(hù)廠家直銷(xiāo)。</p><div
