空調穩壓器有用嗎
除非電(dian)網(wang)電(dian)壓(ya)(ya)(ya)(ya)極低,一(yi)般情況下變壓(ya)(ya)(ya)(ya)器(qi)還是(shi)很有效的(de)(de)。現在(zai)的(de)(de)穩壓(ya)(ya)(ya)(ya)器(qi)一(yi)般都具備(bei)調(diao)壓(ya)(ya)(ya)(ya)功能,既能調(diao)到(dao)220V。至于(yu)品牌和(he)價格(ge),那就不(bu)好說了。可以到(dao)家電(dian)市場看(kan)(kan)看(kan)(kan),比(bi)較下。但是(shi)首先要確定(ding)是(shi)電(dian)壓(ya)(ya)(ya)(ya)過低,如果(guo)確定(ding)是(shi)電(dian)壓(ya)(ya)(ya)(ya)問題(ti)可以安裝穩壓(ya)(ya)(ya)(ya)器(qi)解決。穩壓(ya)(ya)(ya)(ya)器(qi)的(de)(de)作用就是(shi)把過高或過低的(de)(de)電(dian)壓(ya)(ya)(ya)(ya)穩定(ding)在(zai)220V。穩壓(ya)(ya)(ya)(ya)器(qi)要根據你(ni)用電(dian)設(she)備(bei)的(de)(de)功率(lv)來選,要選大(da)于(yu)你(ni)家空(kong)(kong)調(diao)額定(ding)功率(lv)(空(kong)(kong)調(diao)說明書中有標明)的(de)(de)穩壓(ya)(ya)(ya)(ya)器(qi)才能保證空(kong)(kong)調(diao)正常(chang)運行。穩壓(ya)(ya)(ya)(ya)器(qi)的(de)(de)價格(ge)是(shi)功率(lv)越大(da)越貴。
空調穩壓器怎么選?
1、計(ji)算穩壓(ya)器的(de)(de)功率(lv)(lv):空(kong)調(diao)主要負載為壓(ya)縮機(ji),所(suo)以屬于電(dian)機(ji)類負載,電(dian)機(ji)在(zai)瞬間啟(qi)動(dong)(dong)(dong)時(shi)(shi)(shi)電(dian)流是(shi)很(hen)大的(de)(de),雖(sui)然現在(zai)很(hen)多空(kong)調(diao)都是(shi)變頻啟(qi)動(dong)(dong)(dong)的(de)(de),但是(shi)在(zai)啟(qi)動(dong)(dong)(dong)時(shi)(shi)(shi)電(dian)流還是(shi)很(hen)大,那(nei)么在(zai)配備穩壓(ya)器時(shi)(shi)(shi)要留有(you)工作余量,如果空(kong)調(diao)是(shi)2KW,穩壓(ya)器最好(hao)按照3倍功率(lv)(lv),配6KW的(de)(de)穩壓(ya)器。空(kong)調(diao)的(de)(de)功率(lv)(lv)怎么計(ji)算,一(yi)般空(kong)調(diao)有(you)1P、1.5P、2P、3P,1P=0.75KW,大家按照這個(ge)計(ji)算就可以了(le)。
2、穩(wen)壓(ya)器(qi)的功(gong)(gong)率(lv)因(yin)數,目前市場上80%的穩(wen)壓(ya)器(qi)是0.7,20%的穩(wen)壓(ya)器(qi)功(gong)(gong)率(lv)因(yin)素(su)是0.8,什么意思呢?就是10KVA的穩(wen)壓(ya)器(qi),實際(ji)輸(shu)出功(gong)(gong)率(lv) x 0.7=7KW
3、夏(xia)天在(zai)使用(yong)穩壓(ya)器(qi)(qi)時大部(bu)分是由(you)于外(wai)網電壓(ya)偏低,那么(me)在(zai)選用(yong)穩壓(ya)器(qi)(qi)時要(yao)注意留有工(gong)作余量,一般實際負載不要(yao)超過穩壓(ya)器(qi)(qi)功率的80%,為(wei)什么(me)呢?
我們來計(ji)算(suan)一(yi)下就知(zhi)道了,外(wai)(wai)網(wang)電(dian)(dian)(dian)壓220V時:6000W/220V=27A(電(dian)(dian)(dian)流(liu)),外(wai)(wai)網(wang)電(dian)(dian)(dian)壓170V時 : 6000W/170V=35.3A(電(dian)(dian)(dian)流(liu)),經過比較可以看到,輸(shu)入電(dian)(dian)(dian)壓低時電(dian)(dian)(dian)流(liu)越(yue)大,而(er)穩壓器里(li)面的變壓器的線徑是固定的,低壓時承受(shou)的電(dian)(dian)(dian)流(liu)要大很(hen)多。
4、按照上面方(fang)法計算:2KW空調 X2倍 = 4KW, 這(zhe)(zhe)里空調功率(lv)乘(cheng)以2是(shi)因為空調的(de)(de)(de)壓(ya)縮機瞬間(jian)啟動電流大;4KW/ 0.8=5KVA(穩壓(ya)器功率(lv)),這(zhe)(zhe)里除(chu)以0.8是(shi)放置穩壓(ya)器的(de)(de)(de)工作余(yu)量,5KVA / 0.8=6.25KVA(需要(yao)購買的(de)(de)(de)穩壓(ya)器功率(lv)),這(zhe)(zhe)里除(chu)以0.8是(shi)穩壓(ya)器的(de)(de)(de)實際(ji)帶載能力只(zhi)有80%。也(ye)就(jiu)是(shi)2KW的(de)(de)(de)空調配(pei)6KVA的(de)(de)(de)穩壓(ya)器是(shi)這(zhe)(zhe)樣計算的(de)(de)(de)。
