style="text-indent:25px">U型環(huán)是一種供電線路上使用的兩端分別由掛環(huán)與掛板連接件組合構(gòu)成的U形金具。U型環(huán)是線路上的通用金具，其制作是以熱鍍鋅的圓鋼鍛制而成，用途較廣，可以單獨(dú)使用，也可以?xún)蓚€(gè)串裝使用。常作為架空電力線路和變電所聯(lián)結(jié)U型環(huán)串或鋼絞線與桿塔固定時(shí)用，連接時(shí)采用銷(xiāo)釘、眼孔和螺栓連接。U型環(huán)外形與卸扣很相似，但二者作用不同，卸扣是一種起吊用的鎖具，表面處理多是電鍍鋅，而U型環(huán)則是用于供電線路上的熱鍍鋅電力金具。U型環(huán)是用電檢查人員**的一種說(shuō)法，說(shuō)的就是U字形狀的導(dǎo)線電纜。</p><p

style="text-indent:25px">U型環(huán)的強(qiáng)度計(jì)算：U型環(huán)的連接是一種簡(jiǎn)單的連接方式。在U型環(huán)與孔、雙板與單板之間總有一些間隙，因此U型環(huán)要承受彎矩(與U型環(huán)受剪切相比，彎矩居主要地位)故必須計(jì)算器抗彎強(qiáng)度。U型環(huán)的剪應(yīng)力為:Tp-U型環(huán)的許用剪應(yīng)力，U型環(huán)的常用材料鋼Q235、Q245?？扇p=80N/mm2；d-U型環(huán)的直徑。在外荷載P的作用下，并假定荷載通過(guò)孔板傳到U型環(huán)上，沿零件的寬度均勻分布，則U型環(huán)上所產(chǎn)生的彎矩為:M=2(24)兩支之間的距離；經(jīng)熱鍍鋅后的鍛制件、沖壓件的外觀質(zhì)量:沖裁件的剪切斷面斜度偏差小于板厚的十分之一。硅橡膠U型環(huán)的結(jié)構(gòu)簡(jiǎn)單。陜西U型環(huán)費(fèi)用</p><p

style="text-indent:25px">線路運(yùn)行效率高:由于U型環(huán)的風(fēng)雨自潔性好，又不產(chǎn)生零值U型環(huán)，故清掃檢查工作可改為每4~5年一次，從而縮短檢修、停電時(shí)間。重量輕:U型環(huán)自身重量輕在運(yùn)輸、施工作業(yè)中，可減輕工作人員的勞動(dòng)強(qiáng)度。但是事物一分為二，U型環(huán)也存在-些缺點(diǎn):U型環(huán)價(jià)格高。U型環(huán)承受的徑向(垂直于中心線)應(yīng)力很小，因此，使用于耐張桿的高壓U型環(huán)嚴(yán)禁在上面走動(dòng)，或任何形式的徑向荷重，否則將導(dǎo)致折斷。U型環(huán)在施工或平時(shí)運(yùn)行時(shí)嚴(yán)禁硬物跌落、碰擦，因其傘部為硅橡膠，質(zhì)地比較柔嫩，極易損傷而破壞密封性，導(dǎo)致絕緣性能下降。湖南U型環(huán)大修</p><p
