一、安裝家用電表怎樣才算安全
1、電(dian)(dian)(dian)(dian)表(biao)的電(dian)(dian)(dian)(dian)流安(an)(an)培(pei)數(shu),應(ying)適合于家庭(ting)用(yong)的電(dian)(dian)(dian)(dian)器總的用(yong)電(dian)(dian)(dian)(dian)瓦數(shu)。一(yi)般家庭(ting)宜采用(yong)2.5安(an)(an)培(pei)的電(dian)(dian)(dian)(dian)表(biao)較合適。
2、電(dian)(dian)(dian)表(biao)的(de)電(dian)(dian)(dian)壓必須(xu)符合電(dian)(dian)(dian)源(yuan)的(de)電(dian)(dian)(dian)壓,電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓220伏,就不能用110伏的(de)電(dian)(dian)(dian)表(biao),否則電(dian)(dian)(dian)表(biao)的(de)電(dian)(dian)(dian)壓線圈(quan)將會被燒壞引起事故(gu)。
3、電表應安裝在(zai)干燥(zao)的位(wei)置上(shang),不能安裝在(zai)廚(chu)房或煤氣爐的上(shang)方。
4、電(dian)表(biao)安裝高(gao)度要合適(shi)。電(dian)表(biao)中心離地(di)面高(gao)度為(wei)1.5-1.8米。
5、電表(biao)要安(an)裝(zhuang)在配電用的木板上(shang),并要牢固(gu)地裝(zhuang)在可靠及干燥的墻上(shang),不能(neng)裝(zhuang)在門框上(shang)或木板壁(bi)上(shang)。
6、電線(xian)(xian)接(jie)線(xian)(xian)一(yi)定要牢固(gu),接(jie)線(xian)(xian)不能松動或(huo)接(jie)線(xian)(xian)不良,否(fou)則容易產生火花,發生危險。
二、電能表安全使用小知識
1、配用合適的保險絲,不能用(yong)其他金屬(shu)絲(si)代替(ti)。保(bao)險絲的(de)(de)作用(yong)是在電(dian)路發生短路或(huo)嚴(yan)重過載故障時,及時切斷電(dian)源,以保(bao)證安全。選(xuan)擇保(bao)險絲應根據最大使(shi)用(yong)功率或(huo)電(dian)度表(biao)的(de)(de)電(dian)流值來考慮。
2、避免電(dian)度表(biao)過載(zai)運(yun)行,否則不但造成計量不準確,而且(qie)還(huan)有可(ke)能燒毀電(dian)度表(biao)甚至引起火(huo)災(zai)。例如:電(dian)度表(biao)銘牌上標有“5(20)A”,則家庭(ting)用電(dian)電(dian)流最(zui)大值不能超過20 A。
3、換用舊的電(dian)度表(biao)(biao)應送(song)計(ji)(ji)量(liang)部(bu)門校驗。更換電(dian)度表(biao)(biao)前應檢查其外觀,從(cong)外觀上看(kan)應沒有(you)明(ming)顯(xian)的缺(que)陷。如(ru)果(guo)是(shi)新(xin)的電(dian)度表(biao)(biao),不但要求(qiu)鉛(qian)封(feng)完好,而且,一定要附(fu)有(you)出(chu)廠檢驗合格證,安裝后(hou)便可正常使用,并從(cong)零開始計(ji)(ji)數。若(ruo)是(shi)舊的電(dian)度表(biao)(biao),則應先(xian)送(song)計(ji)(ji)量(liang)部(bu)門(過去送(song)供(gong)電(dian)部(bu)門校驗)檢驗合格,并加鉛(qian)封(feng)后(hou)方(fang)司使用。
4、定(ding)(ding)期校(xiao)(xiao)驗電(dian)(dian)度表。使用一段時(shi)間后由于種種原因,存在計量不準的問題,因此,應定(ding)(ding)期校(xiao)(xiao)驗,通(tong)常每隔(ge)3年應對電(dian)(dian)度表校(xiao)(xiao)驗一次。
