①針對(duì)各類變電站直流屏，若顯示交流空開跳閘，但并沒有動(dòng)作。應(yīng)當(dāng)檢查三處地方是否正確：a.接線是否正確可靠；b.控制模塊工作狀態(tài)是否正確;c.空開狀態(tài)和接點(diǎn)是否正確。 </p> <p> ②有人認(rèn)為只要保證直流屏進(jìn)線交流電的供應(yīng)，就可以不用安裝蓄電池，這種想法是不可取的。首先要充分認(rèn)識(shí)到蓄電池是變電站內(nèi)很可靠的直流電源，在變電站交流失電的情況下，蓄電池會(huì)給UPS系統(tǒng)、繼電保護(hù)設(shè)備、故障照明和監(jiān)控裝置等供電，以達(dá)到應(yīng)急的效果。其次蓄電池作為可靠的備用電源，可以彌補(bǔ)電磁開關(guān)合閘時(shí)所需的直流電源，防止直流母線電壓瞬間下降而影響繼電保護(hù)設(shè)備的正常運(yùn)行。 </p> <p> ③合閘硅整流器或控制硅整流器失電：a.交流進(jìn)線電源失電會(huì)產(chǎn)生合閘硅整流器、控制硅整流器、充電電源同時(shí)發(fā)出失電信號(hào)，電源恢復(fù)后即可消除；b.直流輸出端空氣開關(guān)脫扣或硅整流器直流輸出端快熔熔斷更換同規(guī)格的快熔或合上空氣開關(guān)，故障消除；c.如若交流電源缺相，直流輸出電壓只能達(dá)到額定值的60%-70%，用萬用表測(cè)硅整流器輸入端三相電壓即可，處理后便可恢復(fù)正常。樂山伊頓直流屏批發(fā)商直流系統(tǒng)絕緣監(jiān)測(cè)單元是監(jiān)視直流系統(tǒng)絕緣情況一種裝置，實(shí)時(shí)監(jiān)測(cè)線路對(duì)地漏電阻，此數(shù)值根據(jù)具體情況設(shè)定。</p><div

</p> <p> 電焊工更換焊條時(shí)，必須戴電焊手套，以防觸電。 </p> <p> 電焊工離開工作現(xiàn)場必須將電焊機(jī)的電源切斷。 </p> <p> 屏體的接地及屏內(nèi)的保護(hù)接地直接應(yīng)與接地網(wǎng)相連，不得轉(zhuǎn)接，接地使用規(guī)范要求規(guī)格的接地線。 </p> <p>

直流屏的可靠性是其他電源裝置不可替代的，它能滿足變電站和發(fā)電廠這些場合對(duì)電源的高可靠性要求，它為控制負(fù)荷和動(dòng)力負(fù)荷以及直流故障照明負(fù)荷等提供電源，是當(dāng)代電力系統(tǒng)控制、保護(hù)的基礎(chǔ)。直流屏由整流模塊系統(tǒng)、配電單元、降壓單元、電池巡檢單元、開關(guān)量檢測(cè)單元、監(jiān)控系統(tǒng)、絕緣監(jiān)測(cè)單元組成。</p><div
