近年(nian)來廠方提供的(de)產品技術(shu)參數中，環境溫度(du)(du)的(de)表述有所(suo)不同，有40 ℃、55 ℃、60 ℃、65 ℃等。筆者在夏季 炎熱(re)時曾經做過溫度(du)(du)測試實驗：在晴天(tian)氣(qi)溫為37 ℃時，對柱(zhu)上補償箱測溫，箱體(ti)(ti)(ti)金屬(shu)殼體(ti)(ti)(ti)溫度(du)(du)可(ke)達59 ℃，箱體(ti)(ti)(ti)內空(kong)氣(qi)溫度(du)(du)可(ke)達45 ℃，箱體(ti)(ti)(ti)內固(gu)定件溫度(du)(du)可(ke)達48 ℃。顯然環境溫度(du)(du)參數為40 ℃的(de)裝(zhuang)置(zhi)不能滿足要求(qiu)，環境溫度(du)(du)為55 ℃的(de)裝(zhuang)置(zhi)裕度(du)(du)不夠(gou)。由(you)于裝(zhuang)置(zhi)中受溫度(du)(du)影響(xiang) 靈敏的(de)元件是電子電路元器(qi)件，而作為工(gong)業用的(de)電子器(qi)件工(gong)作溫度(du)(du)一般為25～75 ℃，所(suo)以(yi)在充分考慮環境溫度(du)(du)并留有一定裕度(du)(du)的(de)原則下，裝(zhuang)置(zhi)溫度(du)(du)參數以(yi)60 ℃及以(yi)上較適宜(yi)。

汽車生(sheng)產(chan)線濾波(bo)補(bu)償(chang)模(mo)組(zu)不補(bu)償(chang)的(de)原因(yin)

它的(de)(de)作用(yong)實際上就是：提高(gao)整(zheng)(zheng)個(ge)電力(li)(li)系(xi)統(tong)(tong)以(yi)及用(yong)電負載的(de)(de)水平，進一步降低電力(li)(li)設備的(de)(de)內(nei)部所(suo)占容量(liang)(liang);維持電網(wang)的(de)(de)電壓程度，從而使得整(zheng)(zheng)體的(de)(de)供電質(zhi)量(liang)(liang)得以(yi)提高(gao)。它的(de)(de)基本(ben)原理(li)也很簡(jian)單，就是對那些具有(you)容性(xing)的(de)(de)電力(li)(li)設備以(yi)及感性(xing)用(yong)電負載之(zhi)間進行互相地連接，是電力(li)(li)能量(liang)(liang)能在(zai)這兩種負荷(he)之(zhi)間進行隨意的(de)(de)轉換，從而就可以(yi)減少在(zai)整(zheng)(zheng)個(ge)電網(wang)系(xi)統(tong)(tong)中的(de)(de)無(wu)功功率的(de)(de)耗(hao)用(yong)。

但是(shi)從發電機和高壓輸(shu)(shu)電線供給的(de)無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率遠(yuan)遠(yuan)滿足不了負(fu)(fu)荷(he)的(de)需要(yao)，所以在(zai)(zai)電網中要(yao)設置一些無功(gong)(gong)(gong)(gong)補(bu)償(chang)(chang)裝(zhuang)置來補(bu)充(chong)無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率，以保證用(yong)戶對無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率的(de)需要(yao)，這(zhe)樣用(yong)電設備才(cai)能在(zai)(zai)額定(ding)電壓下(xia)工作。無功(gong)(gong)(gong)(gong)補(bu)償(chang)(chang)是(shi)把具(ju)有容性功(gong)(gong)(gong)(gong)率負(fu)(fu)荷(he)的(de)裝(zhuang)置與(yu)感性功(gong)(gong)(gong)(gong)率負(fu)(fu)荷(he)并聯接在(zai)(zai)同(tong)一電路，能量在(zai)(zai)兩(liang)種負(fu)(fu)荷(he)之(zhi)間相互(hu)交換，這(zhe)樣，感性負(fu)(fu)荷(he)所需要(yao)的(de)無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率可由容性負(fu)(fu)荷(he)輸(shu)(shu)出的(de)無功(gong)(gong)(gong)(gong)功(gong)(gong)(gong)(gong)率補(bu)償(chang)(chang)。
