近年來廠方(fang)提(ti)供的產品技術參(can)數(shu)中(zhong)，環境(jing)溫(wen)(wen)(wen)(wen)度(du)(du)的表述(shu)有(you)所不同(tong)，有(you)40 ℃、55 ℃、60 ℃、65 ℃等。筆者在夏季 炎(yan)熱(re)時曾經做過溫(wen)(wen)(wen)(wen)度(du)(du)測試實(shi)驗(yan)：在晴天氣溫(wen)(wen)(wen)(wen)為37 ℃時，對(dui)柱上補償箱測溫(wen)(wen)(wen)(wen)，箱體金屬殼(ke)體溫(wen)(wen)(wen)(wen)度(du)(du)可達(da)59 ℃，箱體內(nei)空氣溫(wen)(wen)(wen)(wen)度(du)(du)可達(da)45 ℃，箱體內(nei)固定件溫(wen)(wen)(wen)(wen)度(du)(du)可達(da)48 ℃。顯(xian)然(ran)環境(jing)溫(wen)(wen)(wen)(wen)度(du)(du)參(can)數(shu)為40 ℃的裝置(zhi)不能滿足(zu)要求，環境(jing)溫(wen)(wen)(wen)(wen)度(du)(du)為55 ℃的裝置(zhi)裕度(du)(du)不夠(gou)。由于裝置(zhi)中(zhong)受(shou)溫(wen)(wen)(wen)(wen)度(du)(du)影響 靈(ling)敏的元件是電子(zi)電路元器件，而作為工業用的電子(zi)器件工作溫(wen)(wen)(wen)(wen)度(du)(du)一般為25～75 ℃，所以在充分考慮環境(jing)溫(wen)(wen)(wen)(wen)度(du)(du)并留有(you)一定裕度(du)(du)的原則(ze)下，裝置(zhi)溫(wen)(wen)(wen)(wen)度(du)(du)參(can)數(shu)以60 ℃及以上較(jiao)適宜。

智(zhi)能建筑中無功(gong)補償元(yuan)件在光伏產業中的作(zuo)用(yong)

它的(de)(de)作用實(shi)際上就是(shi)：提高(gao)整個電(dian)(dian)力(li)系統以及用電(dian)(dian)負載的(de)(de)水平，進一步降低電(dian)(dian)力(li)設備(bei)的(de)(de)內部所占容量;維持電(dian)(dian)網的(de)(de)電(dian)(dian)壓程度，從而使得(de)整體(ti)的(de)(de)供電(dian)(dian)質(zhi)量得(de)以提高(gao)。它的(de)(de)基(ji)本原(yuan)理也很(hen)簡(jian)單，就是(shi)對那些(xie)具有容性的(de)(de)電(dian)(dian)力(li)設備(bei)以及感(gan)性用電(dian)(dian)負載之(zhi)間(jian)(jian)進行(xing)互(hu)相地連(lian)接，是(shi)電(dian)(dian)力(li)能量能在(zai)這兩種(zhong)負荷之(zhi)間(jian)(jian)進行(xing)隨意(yi)的(de)(de)轉(zhuan)換，從而就可以減(jian)少在(zai)整個電(dian)(dian)網系統中的(de)(de)無功功率的(de)(de)耗用。

但是從發電機和高壓輸電線供(gong)給(gei)的(de)(de)無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv)(lv)遠遠滿足不了負荷(he)(he)(he)的(de)(de)需要，所(suo)以在電網中(zhong)要設置(zhi)一(yi)些無(wu)(wu)功(gong)(gong)補償裝置(zhi)來補充無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv)(lv)，以保證用戶對無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv)(lv)的(de)(de)需要，這(zhe)樣用電設備才能在額(e)定(ding)電壓下工作。無(wu)(wu)功(gong)(gong)補償是把具有容(rong)性(xing)(xing)功(gong)(gong)率(lv)(lv)(lv)(lv)(lv)負荷(he)(he)(he)的(de)(de)裝置(zhi)與感(gan)性(xing)(xing)功(gong)(gong)率(lv)(lv)(lv)(lv)(lv)負荷(he)(he)(he)并(bing)聯接在同一(yi)電路，能量在兩種負荷(he)(he)(he)之(zhi)間相(xiang)互交換，這(zhe)樣，感(gan)性(xing)(xing)負荷(he)(he)(he)所(suo)需要的(de)(de)無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv)(lv)可由容(rong)性(xing)(xing)負荷(he)(he)(he)輸出的(de)(de)無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)(lv)(lv)(lv)補償。
