干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)的應用在(zai)(zai)我(wo)們的生(sheng)活中很(hen)常見，但一(yi)般安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)在(zai)(zai)多(duo)層建筑、機場、港口(kou)等房間(jian)(jian)，而(er)在(zai)(zai)外(wai)(wai)(wai)面(mian)看(kan)到的干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)很(hen)少(shao)。很(hen)多(duo)客戶(hu)會問(wen)(wen)(wen)干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)是否可以(yi)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)在(zai)(zai)室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)。以(yi)下(xia)干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)廠家會告訴(su)你。事實上，干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)可以(yi)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)在(zai)(zai)室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)。干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)存在(zai)(zai)很(hen)多(duo)問(wen)(wen)(wen)題(ti)(ti)，比室(shi)(shi)(shi)(shi)(shi)內(nei)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)更麻(ma)煩(fan)。室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)時要(yao)嚴格注意相關事項(xiang)。變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)根據(ju)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)條件(jian)可分(fen)為室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)型和(he)(he)室(shi)(shi)(shi)(shi)(shi)內(nei)型。按照行(xing)業(ye)標準，干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)一(yi)般安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)在(zai)(zai)室(shi)(shi)(shi)(shi)(shi)內(nei)。當客戶(hu)要(yao)求室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)時，需要(yao)配備特殊的保(bao)護套管(guan)(保(bao)護等級(ji)較高，如(ru)(ru)IP44，要(yao)求防止側面(mian)進水，不(bu)提供(gong)頂(ding)部進出水通道)。干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)為什么不(bu)能(neng)直接在(zai)(zai)室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)使(shi)用？如(ru)(ru)果(guo)在(zai)(zai)室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)使(shi)用，目前干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)存在(zai)(zai)以(yi)下(xia)三個絕緣(yuan)(yuan)問(wen)(wen)(wen)題(ti)(ti)：鐵(tie)芯(xin)的張(zhang)力(li)結(jie)構采(cai)用槽(cao)鋼張(zhang)力(li)板(ban)(ban)(ban)結(jie)構。這(zhe)種(zhong)結(jie)構中，張(zhang)力(li)板(ban)(ban)(ban)位于(yu)線圈和(he)(he)鐵(tie)芯(xin)之(zhi)(zhi)間(jian)(jian)，張(zhang)力(li)板(ban)(ban)(ban)的材(cai)料是鐵(tie)，容易生(sheng)銹。另外(wai)(wai)(wai)，室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)天(tian)氣不(bu)好，拉(la)板(ban)(ban)(ban)外(wai)(wai)(wai)表(biao)面(mian)絕緣(yuan)(yuan)層容易損(sun)壞，導致變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)短路(lu)損(sun)壞。另外(wai)(wai)(wai)，拉(la)板(ban)(ban)(ban)位于(yu)線圈和(he)(he)鐵(tie)芯(xin)之(zhi)(zhi)間(jian)(jian)，占(zhan)據(ju)一(yi)定(ding)空間(jian)(jian)，增(zeng)加線圈內(nei)徑(jing)，浪費線圈材(cai)料，增(zeng)加功耗。芯(xin)體(ti)表(biao)面(mian)的自干樹(shu)(shu)脂(zhi)(zhi)絕緣(yuan)(yuan)漆層，日曬雨淋后易風化(hua)開裂(lie)。經過一(yi)定(ding)時間(jian)(jian)后，會出現鐵(tie)芯(xin)表(biao)面(mian)生(sheng)銹、鐵(tie)屑間(jian)(jian)短路(lu)、空載損(sun)耗、空載電流(liu)增(zeng)大等一(yi)系(xi)(xi)列問(wen)(wen)(wen)題(ti)(ti)。低壓(ya)(ya)線圈和(he)(he)高壓(ya)(ya)線圈用環氧樹(shu)(shu)脂(zhi)(zhi)澆注，但環氧樹(shu)(shu)脂(zhi)(zhi)的抗(kang)裂(lie)性和(he)(he)抗(kang)紫外(wai)(wai)(wai)線能(neng)力(li)不(bu)強。當這(zhe)種(zhong)干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)在(zai)(zai)室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)使(shi)用時，環氧樹(shu)(shu)脂(zhi)(zhi)會開裂(lie)，較終絕緣(yuan)(yuan)會完全(quan)損(sun)壞，導致線圈短路(lu)。以(yi)上是干式變(bian)(bian)(bian)壓(ya)(ya)器(qi)(qi)(qi)室(shi)(shi)(shi)(shi)(shi)外(wai)(wai)(wai)安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)三個問(wen)(wen)(wen)題(ti)(ti)的簡要(yao)分(fen)析(xi)。如(ru)(ru)有安(an)(an)裝(zhuang)(zhuang)(zhuang)(zhuang)問(wen)(wen)(wen)題(ti)(ti)，請聯(lian)系(xi)(xi)小編輯，以(yi)供(gong)參考(kao)！
