穿心電容好壞要怎么辨別比較好的
測試穿心電容的好壞有以下兩種穿心電容器裝置是目前電網中使用較多的無功補償裝置,這些并聯穿心電容器裝置(以下簡稱裝置)為電力系統穩定安全運行、改善電能質量、降低電能損耗、增加輸、配電能力等發揮了很好作用,其可用率對于電網電壓調節和降損節能有著重要作用。為了避免裝置發生事故,提高裝置的可用率,除相關標準和行業標準外,電網公司也出臺了一些規范和反事故措施
辦法1:用指(zhi)針(zhen)萬用表(biao)將認意一(yi)(yi)(yi)根表(biao)筆觸摸穿(chuan)心電(dian)(dian)(dian)容(rong)(rong)(rong)一(yi)(yi)(yi)只腳,然(ran)(ran)后用另外一(yi)(yi)(yi)根觸摸另一(yi)(yi)(yi)只,這時(shi)表(biao)針(zhen)會(hui)敏(min)捷上(shang)升(sheng)然(ran)(ran)后緩(huan)慢下降(jiang),這就是(shi)(shi)穿(chuan)心電(dian)(dian)(dian)容(rong)(rong)(rong)的(de)充放(fang)電(dian)(dian)(dian)過(guo)程,闡明穿(chuan)心電(dian)(dian)(dian)容(rong)(rong)(rong)是(shi)(shi)好的(de),假如沒改變,那(nei)么交流表(biao)筆會(hui)呈現上(shang)述現象的(de)話,也(ye)闡明是(shi)(shi)好的(de),假如都不(bu)呈現充放(fang)電(dian)(dian)(dian)或表(biao)針(zhen)上(shang)升(sheng)后不(bu)下降(jiang)就是(shi)(shi)穿(chuan)心電(dian)(dian)(dian)容(rong)(rong)(rong)壞了 。不(bu)下降(jiang)就是(shi)(shi)里邊擊穿(chuan)了,表(biao)針(zhen)一(yi)(yi)(yi)點不(bu)動就是(shi)(shi)失效了,大穿(chuan)心電(dian)(dian)(dian)容(rong)(rong)(rong)用1X10檔小(xiao)穿(chuan)心電(dian)(dian)(dian)容(rong)(rong)(rong)用1X1K或1X10K檔量。
辦法2:用數字式萬用表(biao)(biao)測穿(chuan)心(xin)電(dian)容(rong)(rong):將檔(dang)位(wei)打到穿(chuan)心(xin)電(dian)容(rong)(rong)(依據(ju)你測的(de)穿(chuan)心(xin)電(dian)容(rong)(rong)值選檔(dang)),測驗時(shi)用兩個表(biao)(biao)筆(bi)搭接穿(chuan)心(xin)電(dian)容(rong)(rong)的(de)兩個腳,表(biao)(biao)有(you)(you)必定的(de)數值,然后回(hui)(hui)到無(wu)量(liang)(liang)大位(wei),互換表(biao)(biao)筆(bi)再(zai)試(shi)一次(ci),這次(ci)顯(xian)現數據(ju)巨細(xi)略有(you)(you)誤差(cha),再(zai)回(hui)(hui)到無(wu)量(liang)(liang)大,闡明穿(chuan)心(xin)電(dian)容(rong)(rong)是好(hao)的(de),如不能回(hui)(hui)無(wu)量(liang)(liang)大,闡明漏電(dian),如顯(xian)現無(wu)量(liang)(liang)大,闡明內部斷路或沒(mei)容(rong)(rong)量(liang)(liang)了。
