電表節電器有用嗎
最近一段時間,一種宣稱能省電30%以上的節電器在網上頗為熱銷,不少人都動了心。家用電(dian)表(biao)節電(dian)器真的能節電(dian)嗎?小編特地(di)從(cong)網上(shang)購買了(le)一款58元的家(jia)(jia)用節電器,請專業電工(gong)師(shi)(shi)傅做了(le)一個實驗。電工(gong)師(shi)(shi)傅將節電器接(jie)入一個插(cha)線板,再將插(cha)線板與一只(zhi)可以(yi)測量功率、電流、電壓的電源插(cha)座相(xiang)連,然后(hou)使用不(bu)同(tong)功率的家(jia)(jia)電進(jin)行測試。
電(dian)(dian)工(gong)師(shi)傅先(xian)將吹風(feng)機(ji)(ji)(ji)接(jie)入(ru)(ru)到電(dian)(dian)路中(zhong),插入(ru)(ru)節(jie)(jie)電(dian)(dian)器時(shi),測(ce)量(liang)儀器顯(xian)示(shi)吹風(feng)機(ji)(ji)(ji)的(de)即(ji)(ji)時(shi)功(gong)(gong)率(lv)為1018瓦,當拔(ba)掉節(jie)(jie)電(dian)(dian)器后(hou),吹風(feng)機(ji)(ji)(ji)的(de)即(ji)(ji)時(shi)功(gong)(gong)率(lv)依然是1018瓦,沒有(you)發生變(bian)化(hua)。在(zai)接(jie)入(ru)(ru)的(de)兩分(fen)鐘時(shi)間里,吹風(feng)機(ji)(ji)(ji)的(de)即(ji)(ji)時(shi)功(gong)(gong)率(lv)一(yi)直(zhi)保持不變(bian)。隨后(hou),又對(dui)瓦數相對(dui)較(jiao)小的(de)換(huan)氣(qi)扇和燈泡分(fen)別(bie)進行了測(ce)量(liang),結果顯(xian)示(shi),接(jie)入(ru)(ru)節(jie)(jie)電(dian)(dian)器之前的(de)即(ji)(ji)時(shi)功(gong)(gong)率(lv)為40.14瓦,接(jie)入(ru)(ru)節(jie)(jie)電(dian)(dian)器的(de)即(ji)(ji)時(shi)功(gong)(gong)率(lv)為39.75瓦。實(shi)驗表明,節(jie)(jie)電(dian)(dian)器影響不到電(dian)(dian)器的(de)正(zheng)常消耗(hao)。
相關人士表示,目前節(jie)(jie)(jie)(jie)(jie)電(dian)(dian)器(qi)(qi)在(zai)(zai)家用電(dian)(dian)路上(shang)的(de)應用很(hen)少,節(jie)(jie)(jie)(jie)(jie)電(dian)(dian)器(qi)(qi)最多的(de)應用是在(zai)(zai)工(gong)業(ye)領域。工(gong)業(ye)領域中的(de)節(jie)(jie)(jie)(jie)(jie)電(dian)(dian)設施構造比較復雜(za),一(yi)套工(gong)業(ye)節(jie)(jie)(jie)(jie)(jie)電(dian)(dian)設備(bei)的(de)價格在(zai)(zai)上(shang)萬(wan)元(yuan),節(jie)(jie)(jie)(jie)(jie)電(dian)(dian)效(xiao)果也只有(you)5%。市場上(shang)的(de)家用節(jie)(jie)(jie)(jie)(jie)電(dian)(dian)器(qi)(qi),號稱節(jie)(jie)(jie)(jie)(jie)電(dian)(dian)效(xiao)果能達到20%-50%,肯定不靠(kao)譜。
從能量守(shou)恒定律來看(kan),網(wang)絡上熱賣的(de)這(zhe)種(zhong)節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)器(qi)不僅不會(hui)節(jie)(jie)(jie)電(dian)(dian)(dian)(dian),反而會(hui)產(chan)生(sheng)更多的(de)耗電(dian)(dian)(dian)(dian),這(zhe)種(zhong)節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)器(qi)本身也會(hui)發熱,在使(shi)用過程中會(hui)造(zao)成額外的(de)電(dian)(dian)(dian)(dian)能消耗。想節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)是(shi)(shi)好事(shi),但這(zhe)些節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)器(qi)不少都是(shi)(shi)三無產(chan)品(pin),建議消費者不要輕信(xin)此類產(chan)品(pin),以免上當受騙(pian)。市民們想省電(dian)(dian)(dian)(dian),可以多選購節(jie)(jie)(jie)能型電(dian)(dian)(dian)(dian)器(qi),使(shi)用低谷電(dian)(dian)(dian)(dian),養成隨手(shou)關燈(deng)和電(dian)(dian)(dian)(dian)器(qi)的(de)習慣。
另外,電表節電器并不是真正的降低耗能,而是通過非法的手段使電表計量出現偏差從而達到偷電的目的,而按照供用電條例的規定,這屬于私自改裝電表的行為,肯定會受到處罰。節能器其實就是偷電裝置,私改電表,如果涉及偷電金額過大,還將負法律責任,所以想要購買節電器的市(shi)民(min)可以醒(xing)醒(xing)了。
