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(jia)用電表節電器真的能節電嗎？小(xiao)編特(te)地從網上購買了一(yi)款58元的家(jia)用節電(dian)(dian)(dian)器，請(qing)專業電(dian)(dian)(dian)工(gong)師(shi)傅(fu)做了一(yi)個實驗。電(dian)(dian)(dian)工(gong)師(shi)傅(fu)將節電(dian)(dian)(dian)器接入(ru)一(yi)個插線板，再將插線板與一(yi)只可以(yi)測(ce)量功率、電(dian)(dian)(dian)流、電(dian)(dian)(dian)壓的電(dian)(dian)(dian)源(yuan)插座(zuo)相連，然后使(shi)用不同功率的家(jia)電(dian)(dian)(dian)進行(xing)測(ce)試。

電(dian)工師傅(fu)先將吹風機(ji)(ji)接入(ru)到電(dian)路(lu)中，插入(ru)節(jie)(jie)(jie)電(dian)器(qi)(qi)時(shi)，測量(liang)儀(yi)器(qi)(qi)顯示吹風機(ji)(ji)的即(ji)時(shi)功(gong)率(lv)為1018瓦(wa)(wa)，當拔掉節(jie)(jie)(jie)電(dian)器(qi)(qi)后，吹風機(ji)(ji)的即(ji)時(shi)功(gong)率(lv)依然是1018瓦(wa)(wa)，沒(mei)有發生變化。在接入(ru)的兩分鐘時(shi)間里，吹風機(ji)(ji)的即(ji)時(shi)功(gong)率(lv)一直保持不(bu)變。隨后，又對瓦(wa)(wa)數(shu)相對較小的換氣扇和燈泡分別進行(xing)了測量(liang)，結果顯示，接入(ru)節(jie)(jie)(jie)電(dian)器(qi)(qi)之(zhi)前的即(ji)時(shi)功(gong)率(lv)為40.14瓦(wa)(wa)，接入(ru)節(jie)(jie)(jie)電(dian)器(qi)(qi)的即(ji)時(shi)功(gong)率(lv)為39.75瓦(wa)(wa)。實驗表明，節(jie)(jie)(jie)電(dian)器(qi)(qi)影(ying)響(xiang)不(bu)到電(dian)器(qi)(qi)的正常消耗。

相關人士表示，目(mu)前節(jie)(jie)(jie)電(dian)(dian)器在(zai)家(jia)用(yong)電(dian)(dian)路上(shang)的應用(yong)很少，節(jie)(jie)(jie)電(dian)(dian)器最(zui)多的應用(yong)是在(zai)工業領(ling)域(yu)。工業領(ling)域(yu)中的節(jie)(jie)(jie)電(dian)(dian)設(she)施構造比較復雜，一套工業節(jie)(jie)(jie)電(dian)(dian)設(she)備的價格在(zai)上(shang)萬元，節(jie)(jie)(jie)電(dian)(dian)效(xiao)(xiao)果也只(zhi)有5%。市場上(shang)的家(jia)用(yong)節(jie)(jie)(jie)電(dian)(dian)器，號(hao)稱節(jie)(jie)(jie)電(dian)(dian)效(xiao)(xiao)果能(neng)達到20%-50%，肯定(ding)不靠譜(pu)。

從能(neng)量守(shou)恒(heng)定律來看，網絡上(shang)熱賣的(de)這(zhe)種節(jie)電(dian)(dian)(dian)(dian)器不僅不會(hui)(hui)節(jie)電(dian)(dian)(dian)(dian)，反而會(hui)(hui)產生更多(duo)的(de)耗電(dian)(dian)(dian)(dian)，這(zhe)種節(jie)電(dian)(dian)(dian)(dian)器本(ben)身也(ye)會(hui)(hui)發熱，在使用過(guo)程中會(hui)(hui)造成(cheng)額外的(de)電(dian)(dian)(dian)(dian)能(neng)消(xiao)(xiao)耗。想(xiang)節(jie)電(dian)(dian)(dian)(dian)是(shi)好(hao)事，但(dan)這(zhe)些(xie)節(jie)電(dian)(dian)(dian)(dian)器不少都是(shi)三無產品，建議(yi)消(xiao)(xiao)費者不要輕信此類產品，以免上(shang)當受(shou)騙(pian)。市民們想(xiang)省電(dian)(dian)(dian)(dian)，可以多(duo)選購節(jie)能(neng)型電(dian)(dian)(dian)(dian)器，使用低谷電(dian)(dian)(dian)(dian)，養(yang)成(cheng)隨手關燈和電(dian)(dian)(dian)(dian)器的(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民(min)可(ke)以(yi)醒醒了。
