plc控制柜

是(shi)按電(dian)(dian)(dian)(dian)(dian)氣接線要(yao)求將開關設(she)備、測量儀表、保(bao)護電(dian)(dian)(dian)(dian)(dian)器和輔助(zhu)設(she)備組裝在封閉或半封閉金(jin)屬柜中或屏幅上，其(qi)布置(zhi)應(ying)滿足電(dian)(dian)(dian)(dian)(dian)力系統(tong)正(zheng)(zheng)常(chang)運行(xing)(xing)的要(yao)求，便于檢修，不危及人身(shen)及周(zhou)圍設(she)備的   。正(zheng)(zheng)常(chang)運行(xing)(xing)時可借(jie)助(zhu)手動或自動開關接通或分斷電(dian)(dian)(dian)(dian)(dian)路。故障或不正(zheng)(zheng)常(chang)運行(xing)(xing)時借(jie)助(zhu)保(bao)護電(dian)(dian)(dian)(dian)(dian)器切斷電(dian)(dian)(dian)(dian)(dian)路或報警(jing)。借(jie)測量儀表可顯示(shi)運行(xing)(xing)中的各種參(can)數，還可對某些電(dian)(dian)(dian)(dian)(dian)氣參(can)數進行(xing)(xing)調(diao)整，對偏(pian)離正(zheng)(zheng)常(chang)工作(zuo)狀態進行(xing)(xing)提示(shi)或發出信號。常(chang)用于各發、配、變電(dian)(dian)(dian)(dian)(dian)所中。

控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)又包(bao)括許多種，有電氣控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、變頻控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、低壓(ya)控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、高壓(ya)控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、水泵控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、電源控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、電梯控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、、消防控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)、磚機控(kong)(kong)制(zhi)(zhi)柜(ju)(ju)(ju)(ju)等等。

維修保養

1.斷開電源,檢查PLC控制(zhi)柜的機架是否有(you)的接地,并(bing)使(shi)接地電阻不(bu)大于(yu)4Ω。

2.控(kong)制柜上(shang)有不(bu)同(tong)性(xing)質的電壓(ya)(直流110V;交(jiao)流單相220V;三相交(jiao)流),在(zai)維修保養時分清電路,防止發(fa)生短路事故(gu)。

3.控(kong)制柜上的全部電(dian)器開關,應動(dong)(dong)作靈(ling)活,無(wu)顯著噪(zao)聲,連(lian)接線(xian)結頭和(he)接線(xian)柱應無(wu)松動(dong)(dong)現象,動(dong)(dong)觸頭連(lian)接線(xian)結頭處(chu)鋼絲應無(wu)斷裂現象。

4.用軟刷(shua)或吹風(feng)屏板插(cha)件和全部(bu)電磁開關零件的積塵,并檢查控制柜內電器開關觸(chu)(chu)頭的狀態,接觸(chu)(chu)情(qing)況,線圈外表(biao)的絕緣(yuan)以及(ji)機械部(bu)件的動作是否。

5.   換熔(rong)絲(si)時,應使熔(rong)斷電(dian)流(liu)與該(gai)回路的(de)電(dian)流(liu)相(xiang)匹配。
