三相負載不平衡：很多的安裝LED大屏的工程師并沒有專業(yè)的對于三相負荷平衡的知識概念，因此在接電的時候并沒有注意到要控制三相負荷平衡，只是盲目和隨意的進行電路的接電荷裝配，這在很大程度上造成了三相負荷的不平衡。 </p> <p> 其次，大多數(shù)空調(diào)電路和照明混為一體，所以在特定時間段（例如炎熱天氣）時，*作為單相用電接入，這時作為單相用電的效率就會降低，這樣的差異進一步加劇了配電變壓器三相負荷的不平衡狀況。 </p> <p> <p> 三相不平衡的危害： </p> <p> 1．增加線路的電能損耗。LED大屏大多都是使用三相四線制供電，而電流通過線路導(dǎo)線時，因存在阻抗必將產(chǎn)生電能損耗，其損耗與通過電流的平方成正比。由于有單相負載存在差異時，造成三相負載不平衡在所難免，當三相負載不平衡運行時，沈陽 LCD大屏價格，沈陽 LCD大屏價格，沈陽 LCD大屏價格，中性線即有電流通過。這樣不但相線有損耗，而且中性線也產(chǎn)生損耗，加上諧波的干擾，從而增加了電網(wǎng)線路的嚴重損耗。 </p> 在LED 大屏的使用中，高鐵媒體的受眾定位在高頻商旅，他們作為家庭中堅力量，具有較強的品牌意識。沈陽 LCD大屏價格</p> <span style="display:none;"></span><div

關(guān)于LED大屏幕的安全，（1）屏幕自身，現(xiàn)在流行與租賃市場的LED大屏幕無論清晰度都是箱體方式拼接形成的，箱體材質(zhì)以鋁或鐵為常見，但是無論何種結(jié)構(gòu)何總材質(zhì)的箱體都有堆疊極限，盡管現(xiàn)在部分箱體結(jié)構(gòu)與材質(zhì)已經(jīng)將堆疊承載做的超乎想象，但是還是要了解箱體的承重性能。（2）LED箱體是顯示結(jié)構(gòu)，LED的結(jié)構(gòu)靠LED屏幕的被架決定，很多的供應(yīng)商選擇了高性能的箱體卻沒有配備質(zhì)量過硬的背架系統(tǒng)，LED大屏幕的先天結(jié)構(gòu)缺陷就是重量分布不均與結(jié)構(gòu)基礎(chǔ)小，LED大屏幕的箱體相對較薄但是整體重量卻集中在此區(qū)域，一般背架的厚度也在60-80CM左右，先對較高的高度與較重的箱體，背架顯得過于單薄，一般搭建LED大屏幕要在背架后部加裝相應(yīng)的配重調(diào)整屏幕前后重量比例，但是配重材料不便于運輸與安裝，很多商家會省略配重環(huán)節(jié)，這是一種極其不負責任的為降低成本忽視安全的表現(xiàn)，另外要重視背架與LED基礎(chǔ)的安裝精度，LED屏幕的重量大分布靠前，結(jié)構(gòu)基礎(chǔ)小，安裝中結(jié)構(gòu)的輕微傾斜在屏幕機構(gòu)安全上都會被成倍放大，隨著高度的增加箱體數(shù)量變多結(jié)構(gòu)強度變低，更容易發(fā)生結(jié)構(gòu)變形，這就要求背架有足夠的強度與支撐性。沈陽

大屏的使用中，高鐵媒體的受眾定位在高頻商旅、新中產(chǎn)主流消費人群，他們作為家庭中堅力量，具有較強的品牌意識。對中**品牌的品牌傳播與曝光起著不可估量的作用。高鐵LED旅客信息大屏設(shè)置于安檢口、候車大廳**、進出站口等關(guān)鍵卡位，LED 大屏<span style="display:none;"></span>作為鐵路即時信息官方發(fā)布平臺，天然吸睛，***覆蓋出行人群。高鐵路網(wǎng)有極強的聚客效應(yīng)，通過一站LED 大屏、一次多站投放，實現(xiàn)中國出行人群全覆蓋，LED 大屏**終形成點線面的全國傳播網(wǎng)絡(luò)。 </p><p> 操作LED大屏注意事項 </p> <p> 目前，隨著中國LED大屏發(fā)展產(chǎn)業(yè)不斷增加，在各大城市街頭巷尾的LED大屏幕顯示屏慢慢多起來了，人們消費水平也日益增長，<span style="display:none;"></span>LED大屏照明已逐步運用到家庭的日常生活當中，LED大屏不但提升了城市形象，LED大屏還豐富人們的文化生活，在這方面可以體現(xiàn)了LED大屏產(chǎn)業(yè)的發(fā)展速度是如此快，在我們享受LED大屏帶來經(jīng)濟效益的同時，一些擁有LED大屏的商家并未完全懂得LED大屏操作和使用注意事項，以導(dǎo)致縮短LED大屏的壽命。 LED大屏使用三相四線制供電，而電流通過線路導(dǎo)線時，阻抗將產(chǎn)生電能損耗，其損耗與通過電流的平方成正比。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="沈陽 LCD大屏價格,大屏"

5、屏體內(nèi)嚴禁進水、鐵粉等易于導(dǎo)電的金屬物。LED大屏幕盡量放置在低灰塵的環(huán)境，大的灰塵會對顯示效果造成影響，同時灰塵過多會對電路造成損害。如果因為各種原因進水，請立即斷電并聯(lián)系維修人員，直至屏體內(nèi)顯示板干燥后方可使用。 </p> <p> 6、LED大屏的開關(guān)順序：A：先開啟控制計算機使其能正常運行后再開啟LED大屏屏幕;B：先關(guān)閉LED大屏，再關(guān)閉計算機。 </p> <p> 7、播放時不要長時間處于全白色、全紅色、全綠色、全藍色等全亮畫面，以免造成電流過大，電源線發(fā)熱過大，LED燈損壞，影響顯示屏使用壽命。切勿隨意拆卸、拼接屏體! </p> <p> 8、建議LEDLED大屏幕每天休息時間大于2小時，在梅雨季節(jié)LED大屏幕一個星期至少使用一次以上。一般每月至少開啟屏幕一次，點亮2小時以上。 </p> <p> 9、LED大屏幕表面可以采用酒精進行擦拭，或者使用毛刷、吸塵器進行除塵，不能直接用濕布擦拭。 </p> <p> 10、LED大屏需定期檢查是否正常工作，線路有無損壞，如不工作要及時更換，線路有損壞要及時修補或者更換。LED大屏內(nèi)部線路，非專業(yè)人士禁止觸碰，以免觸電，或者造成線路損壞;如果出現(xiàn)問題，請專業(yè)人士進行檢修戶外LED大屏逐步進入“高清”時代，畫面顯示效果和色彩還原尤其重要。沈陽 LCD大屏價格</p><p style="text-indent:25px">戶外LED大屏不但有廣告創(chuàng)作的藝術(shù)性，更是作為商業(yè)、品牌傳播的重要門戶，這種媒體形式有營銷價值和品質(zhì)。沈陽 LCD大屏價格</p><p> 1、LED大屏監(jiān)控系統(tǒng)應(yīng)用于施工現(xiàn)場的必要性 </p> <p> 在一些建筑工地中，有的施工單位經(jīng)常為了趕工期或降低成本而忽視了安全生產(chǎn)，留下了安全隱患。為了確保建設(shè)工程的施工安全，傳統(tǒng)的監(jiān)督方法效率低下，已經(jīng)不能適應(yīng)近年來城市建設(shè)力度日益加大的新形勢。加強建筑工地的安全監(jiān)管手段，已是擺在建設(shè)安全監(jiān)督部門面前的首要迫切任務(wù)。采用大屏監(jiān)控系統(tǒng)，通過LED大屏實時監(jiān)管工地施工現(xiàn)場，既減輕了監(jiān)管人員的工作量，又加強了調(diào)控監(jiān)管力度，提高了工作效率。 </p> <p> 2、LED大屏監(jiān)控系統(tǒng)原理應(yīng)用于施工安全管理的必然性 </p> <p> 通過LED大屏監(jiān)控系統(tǒng)，施工企業(yè)可對本企業(yè)安裝監(jiān)控系統(tǒng)的建筑工地實施遠程操控和實時查看;工地項目部、項目建設(shè)單位、監(jiān)理單位可操控和使用LED大屏監(jiān)控設(shè)備進行現(xiàn)場實時監(jiān)管。是對目前安全工作傳統(tǒng)管理模式的有益補充。 </p> <p> 3、加強LED大屏監(jiān)控系統(tǒng)的安裝技術(shù)要求增強安全監(jiān)管的有效性 </p> <p> 通過對施工現(xiàn)場的合理布點，努力提高系統(tǒng)在實施遠程監(jiān)控的實用性、適應(yīng)性和靈活性，很大限度地滿足安全監(jiān)督工作的不同需求，實現(xiàn)對施工現(xiàn)場及人員的監(jiān)視需要，是對監(jiān)控效果的有效保證。沈陽 LCD大屏價格</p><p
