一、安裝家用電表怎樣才算安全
1、電(dian)表(biao)的電(dian)流(liu)安(an)培(pei)數,應(ying)適(shi)合于(yu)家(jia)庭用的電(dian)器總(zong)的用電(dian)瓦數。一般家(jia)庭宜采用2.5安(an)培(pei)的電(dian)表(biao)較合適(shi)。
2、電(dian)(dian)(dian)(dian)表的電(dian)(dian)(dian)(dian)壓必須(xu)符合電(dian)(dian)(dian)(dian)源的電(dian)(dian)(dian)(dian)壓,電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓220伏(fu),就(jiu)不(bu)能用110伏(fu)的電(dian)(dian)(dian)(dian)表,否則電(dian)(dian)(dian)(dian)表的電(dian)(dian)(dian)(dian)壓線(xian)圈將(jiang)會被燒壞引起事故。
3、電表應(ying)安裝在(zai)干燥的位(wei)置上(shang),不能安裝在(zai)廚(chu)房或煤氣(qi)爐的上(shang)方。
4、電(dian)表安裝高(gao)度要合適。電(dian)表中心離地面高(gao)度為1.5-1.8米。
5、電表要安裝在配電用的木(mu)板上(shang),并要牢固地裝在可(ke)靠及干燥的墻上(shang),不能裝在門(men)框上(shang)或(huo)木(mu)板壁上(shang)。
6、電線(xian)(xian)接(jie)線(xian)(xian)一(yi)定要牢固,接(jie)線(xian)(xian)不能(neng)松動或(huo)接(jie)線(xian)(xian)不良,否(fou)則(ze)容易產生(sheng)火(huo)花,發生(sheng)危險(xian)。
二、電能表安全使用小知識
1、配用合適的保險絲,不(bu)能用其(qi)他金(jin)屬(shu)絲(si)代替。保(bao)險(xian)(xian)絲的作用是在電(dian)路(lu)發生短路(lu)或嚴重過載(zai)故(gu)障時,及時切斷電(dian)源,以保(bao)證安全。選擇保(bao)險(xian)(xian)絲應根據最大使用功率或電(dian)度表的電(dian)流(liu)值來(lai)考慮。
2、避免電度表過載運行,否則不(bu)但造成(cheng)計量不(bu)準確,而且(qie)還有可能燒毀(hui)電度表甚至引起火災(zai)。例如:電度表銘牌上標有“5(20)A”,則家庭用電電流最(zui)大值(zhi)不(bu)能超(chao)過20 A。
3、換用舊的(de)(de)(de)電(dian)(dian)(dian)(dian)度(du)表(biao)應送(song)計量部門(men)校(xiao)驗(yan)。更換電(dian)(dian)(dian)(dian)度(du)表(biao)前應檢查其(qi)外(wai)觀(guan)(guan),從(cong)外(wai)觀(guan)(guan)上看應沒有明顯的(de)(de)(de)缺陷。如果(guo)是新的(de)(de)(de)電(dian)(dian)(dian)(dian)度(du)表(biao),不但(dan)要求鉛(qian)封(feng)完好,而(er)且,一定要附有出廠(chang)檢驗(yan)合格(ge)證(zheng),安裝后(hou)便可正(zheng)常(chang)使用,并從(cong)零開(kai)始計數。若是舊的(de)(de)(de)電(dian)(dian)(dian)(dian)度(du)表(biao),則應先送(song)計量部門(men)(過去送(song)供電(dian)(dian)(dian)(dian)部門(men)校(xiao)驗(yan))檢驗(yan)合格(ge),并加鉛(qian)封(feng)后(hou)方司(si)使用。
4、定期校驗電度表(biao)(biao)。使用(yong)一段(duan)時間后由于(yu)種種原因,存在計量(liang)不準(zhun)的(de)問(wen)題(ti),因此,應定期校驗,通常每(mei)隔3年應對電度表(biao)(biao)校驗一次。
