電源適配器因其便宜的價格，以及對電器產(chǎn)品和人體自身提供良好的安全保護，深圳LED亮化電源制造商，被廣泛應(yīng)用到各類電器產(chǎn)品上。在我們的日常生活中，經(jīng)常使用到電源適配器的產(chǎn)品已不局限于手機、筆記本電腦、收音機等各類信息技術(shù)或音、視頻設(shè)備，也越來越多地應(yīng)用到電風(fēng)扇、吸塵器、加濕器、空氣凈化器等家用電器產(chǎn)品上。 </p> <p> 3C認證是我國的強制性認證，列入強制性認證目錄的產(chǎn)品必須獲得3C認證才能進行生產(chǎn)、銷售。貼上3C標識的產(chǎn)品通常認為是安全的，可滿足相關(guān)標準的要求。目前，市面上越來越多的家電產(chǎn)品是通過電源適配器進行供電，那么，獲得3C認證的電源適配器，直接給家用電器供電，是否安全可靠？能否滿足家用電器標準的要求？ </p> <p> 電源適配器屬強制性認證產(chǎn)品，深圳LED亮化電源制造商，一般歸分為信息技術(shù)設(shè)備類和音頻、視頻電子設(shè)備類，產(chǎn)品的安全標準分別是：GB 4943，深圳LED亮化電源制造商.1-2011《信息技術(shù)設(shè)備安全第1部分：通用要求》和GB8898-2011《音頻、視頻及類似電子設(shè)備安全要求》。 </p> <p> 一般情況下通過3C認證的電源適配器產(chǎn)品都可以確保使用安全，消費者可以放心使用。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="深圳LED亮化電源制造商" src="http://tyunfile.71360.com/UploadFile/szxskj/637142795370205078/263650.jpg"></div><p> 你知道嗎，電源適配器是可以防雷的，所以即使是在下雨天也可以放心安全使用，那么你知道它是如何做到的嗎？ </p> <p> 因為在電源適配器的電路中裝有壓敏電阻器，壓敏電阻器在電源適配器中主要用來吸收浪涌電壓。起過電壓保護、防雷、抑制浪涌電流、吸收尖峰脈沖、限幅、高壓滅弧、消噪、保護半導(dǎo)體元器件等作用。 </p> <p> <br /> </p> <p> 壓敏電阻器是一種具有瞬態(tài)電壓抑制功能的元件，可以用來代替瞬態(tài)抑制二極管、齊納二極管和電容器的組合。壓敏電阻器可以對充電器電路中的集成電路IC及其它半導(dǎo)體元件進行保護，防止因靜電放電、浪涌及其它瞬態(tài)電流（如雷擊等）而造成對它們的損壞。 </p> <p> 使用時只需將壓敏電阻器并接于被保護的IC或充電器的交流輸入電路上，當(dāng)電壓瞬間高于某一數(shù)值時，壓敏電阻器阻值迅速下降，導(dǎo)通大電流，從而保護IC或電器設(shè)備；當(dāng)電壓低于壓敏電阻器工作電壓值時，壓敏電阻器阻值極高，近乎開路，因而不會影響器件或充電器的正常工作。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="深圳LED亮化電源制造商" src="http://tyunfile.71360.com/UploadFile/szxskj/637142795552910156/908651.jpg"></div><p> 電源適配器應(yīng)用***，那么電源適配器的質(zhì)量問題是我們關(guān)注一個問題，實際上電源適配器中存在著許多的質(zhì)量問題。 </p> <p> 1、產(chǎn)品標識不完整或不規(guī)范。 </p> <p> 標簽應(yīng)包含指導(dǎo)用戶正確安裝和使用的重要信息。正確貼標產(chǎn)品是確保用戶個人和財產(chǎn)安全的基本措施之一。標記需要耐用性和引人注目。正常使用后，標記不應(yīng)脫落，內(nèi)容應(yīng)清潔和區(qū)分。這方面常見問題是沒有中文標識，沒有工廠名稱或商標，沒有型號代碼或型號規(guī)格等。則可能是假冒偽劣產(chǎn)品。 </p> <p> 2、正常工作條件下的加熱不符合要求。 </p> <p> 電源適配器的功能是改變電壓。在電壓轉(zhuǎn)換過程中，由于損耗，需要消耗一部分電能。在電能轉(zhuǎn)換成熱能后，部分熱能通過輻射，對流和傳導(dǎo)傳遞到周圍環(huán)境。熱能的另一部分自身被吸收，使電源適配器的溫度變暖。所以當(dāng)周邊的環(huán)境溫度過高時，我們應(yīng)該停止電源適配器的使用。 </p> <p> 3、短路和過載，存在隱患安全隱患。 </p> <p> 在輸出短路，電容器或二極管短路的情況下，電源適配器的內(nèi)部損耗急劇增加，導(dǎo)致每個部件的溫升。電子電路的設(shè)計和應(yīng)用應(yīng)確保在異常工作和故障條件下，產(chǎn)品各部分的溫升不能超過規(guī)定的要求，否則短路的后果不堪設(shè)想。甚至?xí)砘馂?zāi)。 </p> <p>
