3、可靠性高 采用工業(yè)級(jí)電子元件,具有可靠性高、壽命長(zhǎng)、抗干擾能力強(qiáng)等特點(diǎn),發(fā)光模塊采用進(jìn)口發(fā)光芯片,戶外高亮級(jí),壽命170000小時(shí)。
4、壽命長(zhǎng) 產(chǎn)品設(shè)計(jì)壽命30年,保用10年。

三、工作原理
1. 裝置由模擬指示部分、高壓帶電指示部分、溫濕度控制部分及通信部分組成。
2. 模擬指示電路的開(kāi)關(guān)量輸入信號(hào)取自開(kāi)關(guān)柜中一次元件的輔助觸點(diǎn)。經(jīng)噪聲吸收、光電隔離電路,信號(hào)由CPU進(jìn)行智能邏輯控制處理,驅(qū)動(dòng)動(dòng)態(tài)模擬數(shù)碼管顯示各開(kāi)關(guān)量的分、合狀態(tài);
3. 高壓帶電指示電路的輸入信號(hào)取自與母線相連的高壓帶電傳感器。經(jīng)浪涌吸收、電流抑制、電磁隔離電路,由CPU對(duì)三相電壓信號(hào)進(jìn)行數(shù)字噪聲濾波、相序識(shí)別、幅值計(jì)算后,輸出高壓帶電閉鎖信號(hào),并以高亮度LED指示高壓帶電相及閉鎖狀態(tài);
4. 溫濕度控制電路配用1路溫濕度傳感器,將溫濕度數(shù)值以數(shù)字信號(hào)的形式采集到CPU,經(jīng)過(guò)運(yùn)算處理邏輯判斷,自動(dòng)控制加熱器或風(fēng)機(jī)進(jìn)行工作,以防止凝露的產(chǎn)生;
5. 裝置通過(guò)RS485總線與后臺(tái)監(jiān)控計(jì)算機(jī)進(jìn)行組網(wǎng)通信,能夠方便的實(shí)現(xiàn)一臺(tái)或多臺(tái)開(kāi)關(guān)柜組成的電氣一次系統(tǒng)的實(shí)時(shí)動(dòng)態(tài)運(yùn)行模擬與遠(yuǎn)程環(huán)境監(jiān)控。
四.產(chǎn)品使用方法:
1.按端子的配線功能接好線,并校對(duì)準(zhǔn)確后通電;
2.將各開(kāi)關(guān)量輸入端與公共端短路一下,觀察對(duì)應(yīng)功能的指示是否正常發(fā)光或熄滅;
3.帶電指示器的各個(gè)輸入端分別接上對(duì)應(yīng)的高壓帶電傳感器,某相高壓試驗(yàn)時(shí),對(duì)應(yīng)的帶電指示燈亮,有閉鎖功能時(shí)閉鎖燈亮,閉鎖有效,閉鎖輸出觸點(diǎn)斷開(kāi);高壓斷開(kāi)后帶電指示燈滅,閉鎖解除,閉鎖輸出觸點(diǎn)閉合。
4. 加熱除濕功能實(shí)驗(yàn)只需對(duì)傳感器哈氣,負(fù)載便會(huì)啟控。當(dāng)要強(qiáng)制加熱時(shí),可將按鈕撥到手動(dòng)檔,負(fù)載工作,按鈕撥到自動(dòng)檔,負(fù)載停止工作。
5. 高壓帶電自檢功能:按下高壓帶電自檢按鈕,此時(shí)內(nèi)部電路切換到儀表自檢功能,儀表將內(nèi)部提供3路AC220V交流電壓通過(guò)高壓帶電三相回路,檢測(cè)電路工作狀態(tài)。在自檢狀態(tài)下,高壓帶電指示燈都應(yīng)該處于點(diǎn)亮狀態(tài),并且閉鎖功能啟動(dòng)。將自檢功能切換回工作狀態(tài)時(shí),高壓帶電回路回復(fù)到正常工作狀態(tài)。
