style="text-indent:25px">A型應(yīng)急照明集中電源燈具的故障維修：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。專業(yè)A型應(yīng)急照明電源檢查A型應(yīng)急照明集中電源疏散照明的轉(zhuǎn)換時(shí)間不應(yīng)大于5s。</p><div
