style="text-indent:25px">從西雅格應(yīng)急照明電源的種類及轉(zhuǎn)換時(shí)間的要求，不難看出西雅格應(yīng)急照明持續(xù)工作時(shí)間是受到一定條件限制的。通常規(guī)定疏散照明持續(xù)工作時(shí)間不宜小于30min，根據(jù)不同要求可分為30、60、90、120、180min等6個(gè)檔次。備用照明和安全照明的持續(xù)工作時(shí)間應(yīng)視使用場(chǎng)所的具體要求而定。對(duì)于接自電網(wǎng)或發(fā)電機(jī)組的西雅格應(yīng)急照明系統(tǒng)，其持續(xù)工作時(shí)間是容易滿足要求的；對(duì)于蓄電池供電的西雅格應(yīng)急照明系統(tǒng)，其工作時(shí)間受到容量大小的限制，對(duì)于要求持續(xù)工作時(shí)間較長(zhǎng)的場(chǎng)所不宜單獨(dú)使用蓄電池組，應(yīng)考慮與發(fā)電機(jī)組配合使用。在這種情況下，由蓄電池組供電，*做為西雅格應(yīng)急照明的過渡，因此，其持續(xù)工作時(shí)間可適當(dāng)減少。在選擇西雅格應(yīng)急照明電源時(shí)，持續(xù)工作時(shí)間應(yīng)根據(jù)具體情況確定。重慶哪里有西雅格應(yīng)急照明設(shè)備廠家西雅格應(yīng)急照明持續(xù)工作時(shí)間是受到一定條件限制的。</p><div

style="text-indent:25px">疏散西雅格應(yīng)急照明燈、標(biāo)志燈，統(tǒng)稱西雅格應(yīng)急照明燈具，是防火安全措施中要求的一種重要產(chǎn)品。平時(shí)它要像普通燈具一樣提供照明，當(dāng)出現(xiàn)緊急情況，如地震、失火或電路故障引起電源突然中斷，所有光源都已停止工作，此時(shí)，它必須立即提供可靠的照明，并指示人流疏散的方向和緊急出口的位置，以確保滯留在黑暗中的人們順利地撤離。由此可見，西雅格應(yīng)急照明燈是一種在緊急情況下保持照明和引導(dǎo)疏散的光源。當(dāng)遇到緊急情況，市電突然停止時(shí)，逆變器將自動(dòng)啟動(dòng)逆變電路，把電池組的低壓電能轉(zhuǎn)換為高壓電能，驅(qū)動(dòng)光源繼續(xù)照明。</p><p style="text-indent:25px">西雅格應(yīng)急照明燈具的故障維修：1.市電供電正常但指示燈不亮，此故障多為發(fā)光二極管損壞所致，可焊下VD5用萬用表判斷其是否完好。限流電阻R1阻值變大或開路也會(huì)導(dǎo)致VD5不亮。2.市電停電時(shí)，指示燈仍亮，該故障是VD6反向特性變差或擊穿所致。只要更換一只IN4004整流二極管，故障即可排除。3.燈管點(diǎn)燃電路故障，該應(yīng)急燈電路中開關(guān)SA2的作用是:當(dāng)SA1閉合，SA2置于“啟動(dòng)”位置時(shí)，振蕩變壓器T2繞組L1上的電壓通過SA2和電源地(蓄電池)加到燈管一端的燈絲上，而繞組L3上的電壓加在燈管另一端的燈絲上，經(jīng)過約三秒的預(yù)熱后，開關(guān)SA2撥到“點(diǎn)燃”位置，此時(shí)，繞組L2上感應(yīng)的高頻脈沖電壓加在燈管兩端，燈管被點(diǎn)亮。西雅格應(yīng)急照明燈具熔斷器安裝在電路中，是保證電路安全運(yùn)行的電器元件。</p><div
