ABB快速熔斷電阻器 OFAF000H32A
ABB熔斷器分為500V和690V兩種，都是為了滿足現(xiàn)代化工業(yè)和電力系統(tǒng)要求設計的，具備了分斷*高短路電流的能力。400V熔斷器的短路分斷能力可超過100 kA。另外，690V熔斷器分為雙顯和單顯熔斷器，雙顯全系列產(chǎn)品設計及工藝制造方法，雙重保障知識保證不需要借助任何儀器準確及時檢測系統(tǒng)故障，提供供電可靠性。分斷能力達到80KA。快速熔斷器設計和測試按照IEC60269標準進行。額定電壓達到690VAC，電流20-1000A，分斷能力高達200KA RMS Sym出色的限流能力熔斷器擁有出色的限流能力，配合標準容量的電纜和元器件便可確保接觸器和繼電器的正常運行，而截斷電流值非常小。配合類型2 表示電路中的所有元件必須在短路發(fā)生后仍可繼續(xù)使用，熔斷器有效保證了這一點，且不需要額外擴容。
熔斷器如何限流
為了避免危險，并對設備和電路造成的傷害，必須以*快的速度分斷短路電流。由于短路電流產(chǎn)生的溫升非常快，會導致設備的癱瘓。而熔斷器可對溫升迅速反應，并且其限流能力很強。熔斷器中的石英砂阻隔了短路飛弧產(chǎn)生的高溫，與此同時熔體由于溫度上升很快而熔斷。熔斷器系統(tǒng)的維護成本很低。熔斷器本身可承受很高的短路電流沖擊，每當熔斷后，更換的只是熔斷器本身。由于更換熔斷器非常簡單迅速，使用熔斷器做保護的系統(tǒng)可減少工廠的斷電時間，并降低維護成本。
