高壓電(dian)機啟(qi)動(dong)(dong)(dong)柜，簡(jian)稱高壓啟(qi)動(dong)(dong)(dong)柜，有多(duo)種啟(qi)動(dong)(dong)(dong)方(fang)(fang)式(shi)(shi)，因各(ge)自特點及(ji)優(you)缺點，適用不同應用場合，下面來介紹(shao)其中(zhong)3種降壓啟(qi)動(dong)(dong)(dong)方(fang)(fang)式(shi)(shi)的(de)優(you)缺點分析：自耦變壓器啟(qi)動(dong)(dong)(dong)方(fang)(fang)式(shi)(shi)、極板可移動(dong)(dong)(dong)式(shi)(shi)水(shui)電(dian)阻啟(qi)動(dong)(dong)(dong)方(fang)(fang)式(shi)(shi)、熱變電(dian)阻式(shi)(shi)水(shui)電(dian)阻啟(qi)動(dong)(dong)(dong)方(fang)(fang)式(shi)(shi)的(de)各(ge)自優(you)缺點分析，以及(ji)如何選擇合適的(de)啟(qi)動(dong)(dong)(dong)方(fang)(fang)式(shi)(shi)。

襄陽10kv軟啟動柜,襄陽10kv軟啟動柜價格分享自耦變壓器啟動方式

自耦變壓器啟動方式的主要(yao)優(you)點在于(yu)后期不需(xu)要(yao)維護，而(er)且容(rong)量可(ke)以設計的很大，在國外(wai)也被廣泛使(shi)用，并且占地(di)面(mian)積也相對(dui)較小，需(xu)要(yao)的土(tu)建投資成本比較低，但設備本身的投資成本相對(dui)較高(gao);缺點就是自耦變壓器只有3個端頭，端電(dian)壓可(ke)調節范(fan)圍有限(xian)，啟動時產生的一(yi)個二次沖(chong)擊(ji)會對(dui)電(dian)網和設備造成沖(chong)擊(ji)。

極板可移動(dong)式水電阻啟動(dong)方式

極板(ban)可移動式(shi)(shi)水電(dian)(dian)(dian)阻(zu)啟動方式(shi)(shi)相(xiang)對(dui)來(lai)說啟動的(de)(de)初始電(dian)(dian)(dian)流要小(xiao)，由于極板(ban)的(de)(de)移動是靠小(xiao)變頻器和伺服電(dian)(dian)(dian)機拖(tuo)動，極板(ban)的(de)(de)可靠性從理論上講，比(bi)熱變電(dian)(dian)(dian)阻(zu)式(shi)(shi)的(de)(de)固定(ding)極板(ban)低;極板(ban)可移動式(shi)(shi)水電(dian)(dian)(dian)阻(zu)啟動的(de)(de)優點是電(dian)(dian)(dian)阻(zu)值可調(diao)，可在現場隨時調(diao)整(zheng)啟動阻(zu)值，來(lai)達到調(diao)節電(dian)(dian)(dian)機端(duan)電(dian)(dian)(dian)壓(ya)及母(mu)線(xian)電(dian)(dian)(dian)壓(ya)的(de)(de)目的(de)(de)，啟動完成時無二次沖(chong)擊。

熱變(bian)電阻式(shi)水電阻啟動(dong)方式(shi)

熱變電(dian)(dian)(dian)阻(zu)(zu)式(shi)水(shui)(shui)(shui)電(dian)(dian)(dian)阻(zu)(zu)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)方(fang)式(shi)在(zai)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)過程(cheng)中電(dian)(dian)(dian)流(liu)波動(dong)(dong)(dong)(dong)(dong)比較小，電(dian)(dian)(dian)壓下(xia)降幅度也屬(shu)于正常(chang)范圍，其他數(shu)據(如電(dian)(dian)(dian)流(liu)、啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)時(shi)間、電(dian)(dian)(dian)流(liu)倍數(shu))也基本與極(ji)(ji)板可(ke)(ke)(ke)移(yi)(yi)動(dong)(dong)(dong)(dong)(dong)式(shi)水(shui)(shui)(shui)電(dian)(dian)(dian)阻(zu)(zu)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)方(fang)式(shi)相同。熱變電(dian)(dian)(dian)阻(zu)(zu)式(shi)水(shui)(shui)(shui)電(dian)(dian)(dian)阻(zu)(zu)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)方(fang)式(shi)的優點也是(shi)電(dian)(dian)(dian)阻(zu)(zu)值可(ke)(ke)(ke)調(diao)，雖與極(ji)(ji)板可(ke)(ke)(ke)移(yi)(yi)動(dong)(dong)(dong)(dong)(dong)式(shi)水(shui)(shui)(shui)電(dian)(dian)(dian)阻(zu)(zu)調(diao)節阻(zu)(zu)值相比，較繁(fan)瑣(suo)(現在(zai)熱變電(dian)(dian)(dian)阻(zu)(zu)也已經出現了(le)在(zai)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)前可(ke)(ke)(ke)以調(diao)整極(ji)(ji)板，在(zai)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)過程(cheng)中極(ji)(ji)板不動(dong)(dong)(dong)(dong)(dong)的改(gai)進型熱變電(dian)(dian)(dian)阻(zu)(zu)式(shi)水(shui)(shui)(shui)電(dian)(dian)(dian)阻(zu)(zu))，但由于極(ji)(ji)板在(zai)啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)過程(cheng)中不變化，所以安(an)全性(xing)優于極(ji)(ji)板可(ke)(ke)(ke)移(yi)(yi)動(dong)(dong)(dong)(dong)(dong)式(shi)水(shui)(shui)(shui)電(dian)(dian)(dian)阻(zu)(zu)。啟(qi)(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)完成時(shi)無二次沖擊(ji)。

極板可移動(dong)式水電(dian)阻(zu)和熱變電(dian)阻(zu)式水電(dian)阻(zu)啟動(dong)方式的共同缺(que)點，是每次啟動(dong)后液(ye)體溫度上升較大(da)，不能(neng)在(zai)短時間內多次啟動(dong)。啟動(dong)容量設計的不大(da)，目前還(huan)只(zhi)是在(zai)功率為18000KW以下的電(dian)機(ji)上應用，主要還(huan)是集中在(zai)功率為12000KW以下的電(dian)機(ji)。占地面(mian)積很大(da)，土建投(tou)資成本相對較高(gao)，后期(qi)需要進行維護。
