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)(dian)表節電(dian)(dian)器真的(de)能節電(dian)(dian)嗎?小編特(te)地從網上購(gou)買了一(yi)(yi)款(kuan)58元的(de)家用(yong)節(jie)(jie)電器,請專(zhuan)業電工師(shi)傅(fu)做了一(yi)(yi)個實驗。電工師(shi)傅(fu)將節(jie)(jie)電器接入一(yi)(yi)個插(cha)線板,再將插(cha)線板與一(yi)(yi)只可以(yi)測量功(gong)率(lv)、電流、電壓的(de)電源插(cha)座相連,然后使用(yong)不同功(gong)率(lv)的(de)家電進行測試。
電(dian)工(gong)師(shi)傅先(xian)將(jiang)吹風(feng)機(ji)(ji)接入(ru)到電(dian)路(lu)中,插入(ru)節(jie)電(dian)器(qi)(qi)時(shi),測量(liang)儀(yi)器(qi)(qi)顯示吹風(feng)機(ji)(ji)的(de)即(ji)時(shi)功(gong)(gong)率為(wei)(wei)1018瓦(wa)(wa)(wa)(wa),當拔掉節(jie)電(dian)器(qi)(qi)后(hou),吹風(feng)機(ji)(ji)的(de)即(ji)時(shi)功(gong)(gong)率依然是(shi)1018瓦(wa)(wa)(wa)(wa),沒有發(fa)生變化。在接入(ru)的(de)兩(liang)分(fen)鐘時(shi)間里,吹風(feng)機(ji)(ji)的(de)即(ji)時(shi)功(gong)(gong)率一(yi)直保(bao)持(chi)不變。隨后(hou),又對瓦(wa)(wa)(wa)(wa)數(shu)相對較小(xiao)的(de)換(huan)氣(qi)扇(shan)和燈(deng)泡(pao)分(fen)別(bie)進(jin)行了測量(liang),結果顯示,接入(ru)節(jie)電(dian)器(qi)(qi)之前的(de)即(ji)時(shi)功(gong)(gong)率為(wei)(wei)40.14瓦(wa)(wa)(wa)(wa),接入(ru)節(jie)電(dian)器(qi)(qi)的(de)即(ji)時(shi)功(gong)(gong)率為(wei)(wei)39.75瓦(wa)(wa)(wa)(wa)。實驗表明,節(jie)電(dian)器(qi)(qi)影(ying)響不到電(dian)器(qi)(qi)的(de)正常消耗。
相關人(ren)士表示,目前節(jie)電(dian)(dian)器在家用(yong)電(dian)(dian)路(lu)上(shang)(shang)的應(ying)用(yong)很少,節(jie)電(dian)(dian)器最(zui)多的應(ying)用(yong)是在工(gong)(gong)業(ye)(ye)領域。工(gong)(gong)業(ye)(ye)領域中的節(jie)電(dian)(dian)設施(shi)構造比較(jiao)復雜,一套(tao)工(gong)(gong)業(ye)(ye)節(jie)電(dian)(dian)設備的價格在上(shang)(shang)萬(wan)元,節(jie)電(dian)(dian)效(xiao)果也(ye)只有5%。市場上(shang)(shang)的家用(yong)節(jie)電(dian)(dian)器,號(hao)稱節(jie)電(dian)(dian)效(xiao)果能達到20%-50%,肯定不靠譜。
從能(neng)量守恒定律來看(kan),網(wang)絡(luo)上熱(re)賣的(de)這(zhe)種(zhong)節(jie)電(dian)(dian)(dian)器(qi)不(bu)僅不(bu)會(hui)節(jie)電(dian)(dian)(dian),反而會(hui)產(chan)生更多的(de)耗電(dian)(dian)(dian),這(zhe)種(zhong)節(jie)電(dian)(dian)(dian)器(qi)本身也會(hui)發熱(re),在使(shi)用(yong)過程(cheng)中(zhong)會(hui)造成額(e)外的(de)電(dian)(dian)(dian)能(neng)消(xiao)耗。想(xiang)(xiang)節(jie)電(dian)(dian)(dian)是好(hao)事(shi),但這(zhe)些節(jie)電(dian)(dian)(dian)器(qi)不(bu)少都是三無產(chan)品,建議消(xiao)費者不(bu)要(yao)輕信此類(lei)產(chan)品,以(yi)(yi)免上當受騙。市民們想(xiang)(xiang)省電(dian)(dian)(dian),可以(yi)(yi)多選購(gou)節(jie)能(neng)型電(dian)(dian)(dian)器(qi),使(shi)用(yong)低(di)谷電(dian)(dian)(dian),養成隨手關燈(deng)和電(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)民可以醒醒了。
