如果刻度盤(pán)有反射鏡，應(yīng)使指針和指針在鏡中的影保重合，以減小誤差。5.維護(hù)方法(1)由于磁電系電流表的過(guò)載能力很小，使用時(shí)一定要注意連接電路的極性和量限的選擇。(2)若在測(cè)量中發(fā)現(xiàn)指針?lè)聪蚱D(zhuǎn)或正向偏轉(zhuǎn)超過(guò)標(biāo)度尺上滿(mǎn)刻度線(xiàn)，應(yīng)立即斷電停止測(cè)量，待連接正確或重新選擇更大量限的電流表后再進(jìn)行測(cè)量。

口碑好的韓國(guó)電源powerplaza,SFS5-15C加工 斷路器本體結(jié)構(gòu)如圖一斷路器本體部分由導(dǎo)電回路，絕緣系統(tǒng)，密封件和殼體組成。整體結(jié)構(gòu)為三相共箱式。其中導(dǎo)電回路由進(jìn)出線(xiàn)導(dǎo)電桿，進(jìn)出線(xiàn)絕緣支座，導(dǎo)電夾，軟連接與真空滅弧室連接而成。操作機(jī)構(gòu)如圖二此機(jī)構(gòu)為電動(dòng)儲(chǔ)能，電動(dòng)分合閘，同時(shí)具有手動(dòng)功能。 3、對(duì)可能感應(yīng)出高壓電的設(shè)備，必須消除這種可能性后，才能進(jìn)行測(cè)量。4、被測(cè)物表面要清潔，電阻，確保測(cè)量結(jié)果的正確性。5、兆歐表使用時(shí)應(yīng)放在平穩(wěn)、牢固的地方，且遠(yuǎn)離大的外電流導(dǎo)體和外磁場(chǎng)。6、測(cè)量時(shí)必須正確接線(xiàn)。
GB1208-2016電流互感器第5.2項(xiàng)中規(guī)定標(biāo)準(zhǔn)的電流互感器二次電流為1A和5A，優(yōu)選值為5A，當(dāng)傳輸距離較大時(shí)應(yīng)選1A。1、線(xiàn)路功耗降低線(xiàn)路功耗與通過(guò)電流平方成正比，二次電流為1A的電流互感器比5A減低功耗25倍，即1A的功耗僅為5A的4%。
磁通量是標(biāo)量，但有正、負(fù)，正、負(fù) 不代表方向，僅代表磁感線(xiàn)穿入或穿出。同學(xué)們能不能想到其他類(lèi)似的物理量呢。比如，電流，也是有“運(yùn)動(dòng)方向”的標(biāo)量。當(dāng)一個(gè)面有兩個(gè)方向的磁感線(xiàn)穿過(guò)時(shí)，磁通量的計(jì)算應(yīng)算“純收入”，即ф=ф-ф（ф為正向磁感線(xiàn)條數(shù)，ф為反向磁感線(xiàn)條數(shù)。 照明對(duì)象有建筑物或構(gòu)筑物，廣場(chǎng)、道路和橋梁，機(jī)場(chǎng)、車(chē)站和碼頭，名勝古跡，園林綠地，江河水面，商業(yè)街和廣告標(biāo)志以及城市市政設(shè)施等，其目的就是利用燈光講照明對(duì)象的景觀(guān)加以重塑，并有機(jī)地組合成一個(gè)協(xié)調(diào)、優(yōu)美壯觀(guān)和富有特色的夜景圖畫(huà)，以此來(lái)一個(gè)城市或地區(qū)的夜間形象。
