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。家用電表(biao)節(jie)電器真(zhen)的能(neng)節(jie)電嗎？小編特地從(cong)網上購買(mai)了一(yi)(yi)款(kuan)58元的家用節電(dian)(dian)器，請專業電(dian)(dian)工師傅做了一(yi)(yi)個實驗。電(dian)(dian)工師傅將(jiang)節電(dian)(dian)器接入一(yi)(yi)個插(cha)線板，再將(jiang)插(cha)線板與一(yi)(yi)只(zhi)可以測(ce)量功率、電(dian)(dian)流、電(dian)(dian)壓的電(dian)(dian)源插(cha)座相連(lian)，然后(hou)使(shi)用不同功率的家電(dian)(dian)進行測(ce)試。

電(dian)(dian)工師(shi)傅先將吹(chui)風(feng)(feng)機(ji)接入到(dao)電(dian)(dian)路中(zhong)，插入節(jie)電(dian)(dian)器(qi)時(shi)(shi)，測(ce)(ce)量儀器(qi)顯(xian)示吹(chui)風(feng)(feng)機(ji)的(de)即(ji)(ji)(ji)時(shi)(shi)功(gong)(gong)(gong)率(lv)(lv)為1018瓦(wa)，當拔掉節(jie)電(dian)(dian)器(qi)后，吹(chui)風(feng)(feng)機(ji)的(de)即(ji)(ji)(ji)時(shi)(shi)功(gong)(gong)(gong)率(lv)(lv)依然(ran)是(shi)1018瓦(wa)，沒有(you)發生變化。在(zai)接入的(de)兩分鐘時(shi)(shi)間里，吹(chui)風(feng)(feng)機(ji)的(de)即(ji)(ji)(ji)時(shi)(shi)功(gong)(gong)(gong)率(lv)(lv)一直保持(chi)不變。隨后，又對瓦(wa)數相(xiang)對較小(xiao)的(de)換氣扇和燈泡分別進行(xing)了測(ce)(ce)量，結果顯(xian)示，接入節(jie)電(dian)(dian)器(qi)之(zhi)前的(de)即(ji)(ji)(ji)時(shi)(shi)功(gong)(gong)(gong)率(lv)(lv)為40.14瓦(wa)，接入節(jie)電(dian)(dian)器(qi)的(de)即(ji)(ji)(ji)時(shi)(shi)功(gong)(gong)(gong)率(lv)(lv)為39.75瓦(wa)。實(shi)驗表明，節(jie)電(dian)(dian)器(qi)影響不到(dao)電(dian)(dian)器(qi)的(de)正常(chang)消耗(hao)。

相關人士表示，目前節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)器在家(jia)用(yong)(yong)電(dian)(dian)(dian)(dian)路上(shang)的應用(yong)(yong)很少，節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)器最多的應用(yong)(yong)是在工業(ye)領(ling)域。工業(ye)領(ling)域中的節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)設施構造比較復雜(za)，一套工業(ye)節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)設備的價(jia)格在上(shang)萬元(yuan)，節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)效果也只(zhi)有5%。市(shi)場上(shang)的家(jia)用(yong)(yong)節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)器，號稱節(jie)(jie)(jie)電(dian)(dian)(dian)(dian)效果能達到20%-50%，肯定(ding)不靠譜。

從能(neng)量守恒定律(lv)來(lai)看，網絡上(shang)熱賣的(de)這種(zhong)節電(dian)(dian)(dian)(dian)(dian)器不(bu)僅不(bu)會(hui)節電(dian)(dian)(dian)(dian)(dian)，反而會(hui)產生(sheng)更多的(de)耗(hao)電(dian)(dian)(dian)(dian)(dian)，這種(zhong)節電(dian)(dian)(dian)(dian)(dian)器本身(shen)也會(hui)發熱，在使用(yong)過程中會(hui)造(zao)成額外(wai)的(de)電(dian)(dian)(dian)(dian)(dian)能(neng)消(xiao)耗(hao)。想節電(dian)(dian)(dian)(dian)(dian)是好事(shi)，但這些節電(dian)(dian)(dian)(dian)(dian)器不(bu)少都是三無產品(pin)，建議消(xiao)費(fei)者(zhe)不(bu)要輕信此(ci)類產品(pin)，以(yi)免上(shang)當受(shou)騙。市民們想省電(dian)(dian)(dian)(dian)(dian)，可以(yi)多選購(gou)節能(neng)型電(dian)(dian)(dian)(dian)(dian)器，使用(yong)低谷電(dian)(dian)(dian)(dian)(dian)，養成隨手關(guan)燈和電(dian)(dian)(dian)(dian)(dian)器的(de)習(xi)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(de)市民可以醒醒了。
