href='http:///' target='_blank' class='key_tag'><font color=#2086ee><strong>加熱管</strong></font></a>，要接在380V的電路中，需要采用星形接法。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">如果是額定電壓380V的加熱管，要接在380V的電路中，需要采用三角形接法。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（1）星形接法：</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">①星形接法：有中性點，每個元件的首端連在一起（這個點稱中性點），三個尾端分別接三根相線的接線方式。這時有兩種電壓等級，即線電壓和相電壓，且線電壓等于相電壓的約1.73倍，線電流等于相電流。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">②三個元件額定電壓為220V時；如果三個元件電阻值不同，則中性點應該接零線。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（2）三角形接法：</span></p><p style="text-align:center"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;"><img src="/data/upload/image/20190222/1550828308255651.jpg" alt="U型翅片加熱管價格"

"Microsoft YaHei"; font-size: 16px;">①三角形接法：<a href='http:///' target='_blank' class='key_tag'><font color=#2086ee><strong>電加熱管</strong></font></a>每個元件的首端接另一個元件的尾端（也就是首尾相接），三個接點分別接三根相線的接線方式；</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">②三角形接法的特點：三個電加熱管元件額定電壓為380V；這時只有一種電壓等級，線電壓等于相電壓，線電流等于相電流的約1.73倍。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（3）需要注意的是本來星形接法是不能接成三角形的，（如果接成三角形，這時相電壓升高到約1.73倍，長時間運行必然燒毀加熱管）。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（4）同樣本來三角形接法也不能接成星形，（如果接成星形，這時相電壓降低到約1.73倍，達不到正常功率，如果帶額定負載，那么這時屬于過載狀態(tài)，時間一長也必然燒毀加熱管）。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">（5）一般3-4KW以下較小功率一般接成星形，以上較大功率一般接成三角形。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">星型接法相電流等于線電流，線電壓是相電壓的根號3倍，三角接法線電壓等于相電壓，線電流是相電流的1.73倍，對于三相對稱負載接成某種連接。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">工藝：翅片加熱管它是由翅片纏繞在加熱管的外表層起散熱作用。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">翅片式電加熱管是在普通加熱表面纏繞金屬散熱片，與普通加熱管相比散熱面積擴大了2～3倍，即翅片加熱管所允許的表面功率負荷是普通加熱管的3～4倍。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">由于加熱管的長度縮短，使得本身的熱損失減小，在相同的功率條件下，具有升溫快、發(fā)熱均勻、散熱性能好、熱效率高、使用壽命長、加熱裝置體積小，成本低等優(yōu)點。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">根據(jù)用戶要求進行了合理的設計，便于安裝。</span></p><p style="line-height: 2em; text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">產(chǎn)品在機械制造、汽車、紡織、食品、家電等行業(yè)，尤其在空調(diào)器風幕行業(yè)得到廣泛應用。</span></p></div> <h3 class="tag">本文網(wǎng)址：http:///news/448.html </h3> <h3 class="tag">關鍵詞：<a
