Hi，大家好，眾所周知創聯匯通是一家經營多年的專業變壓器電力公司，對于干式變壓器、油浸式變壓器、地埋式變壓器、箱式變壓器等有這豐富的制造經驗和完善的服務解決方案。那么今天創聯匯通繼續為大家分享變壓器行業知識。 干式變壓器有載開關

　　目前國內的該種開關主要用于油浸變壓器中，開關也以變壓器油為絕緣介質。 有個別用于干式變壓器的開關，也是由油浸開關脫胎而來，結構形式沒多大改變， 只是加大了結構尺寸。這些開關大部分為圓筒形，其切換開關部分采用旋轉凸輪 打開或接通各通斷觸頭，其凸輪面受滾動和滑動兩種摩擦力作用，受力條件惡劣， 振動強烈，噪音大，使用壽命短。分接選擇器中采用槽輪機構傳動，動觸頭為寬 夾板式，能跨接兩觸頭，屬帶電移動觸頭，速度不均勻，運動不平穩，容易造成 觸頭燒損。定觸頭排列主要是圓筒形，而干式變壓器的分接觸頭是一平面型，所 以引線相互交錯，容易造成線間短路或線端錯接現象。由于上述問題，該種開關 已不能適應干式變壓器的需要。

　　本實(shi)用新(xin)型的(de)(de)目的(de)(de)是(shi)克服現有(you)技術的(de)(de)缺(que)陷(xian)，提供一種尤其適合干式變壓器(qi)的(de)(de) 有(you)載(zai)開關，增加了(le)該種開關的(de)(de)可靠(kao)性，縮小(xiao)了(le)體積。

　　本實用(yong)新型(xing)的(de)(de)(de)(de)(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)(de)(de)(de)(de)是(shi)以如(ru)下(xia)(xia)(xia)(xia)方式實現的(de)(de)(de)(de)(de)(de)(de)(de)(de)：它仍(reng)涉及動(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)(dong)力(li)裝(zhuang)(zhuang)置(zhi)(zhi)、切(qie)換(huan)開(kai)關(guan)(guan)和(he)分(fen)

　　本實用(yong)新(xin)型結(jie)構簡單，整(zheng)體(ti)尺寸(cun)小，能(neng)與干式(shi)變壓器(qi)相適應。由于切(qie)換(huan)開(kai)關 采用(yong)了壓簧式(shi)無(wu)沖擊往復凸(tu)輪(lun)副機(ji)構，切(qie)換(huan)開(kai)關的凸(tu)輪(lun)副受力(li)條件好，機(ji)械效率 高，同等條件下機(ji)械壽(shou)命由原來(lai)的不足50萬次(ci)(ci)提高到65萬次(ci)(ci)以上，整(zheng)體(ti)噪音也大 大降低。分(fen)接(jie)選擇器(qi)單雙檔動(dong)觸(chu)(chu)頭有兩套傳動(dong)機(ji)構，運(yun)動(dong)平穩(wen)，動(dong)觸(chu)(chu)頭位(wei)置精度 高，動(dong)靜觸(chu)(chu)頭間無(wu)帶電分(fen)離(li)現象，觸(chu)(chu)頭不燒損。定(ding)觸(chu)(chu)頭排(pai)列能(neng)方便(bian)地與變壓器(qi)各 分(fen)接(jie)觸(chu)(chu)頭相
