產品簡述
DW15-630萬能式斷路器(以下簡稱斷路器)及DWX15-630萬能式限流斷路器(以下簡稱限流斷路器)主要用於交流50Hz,額定電流至630A,額定工作電壓380V的配電網絡中,用來分配電能和保護線路及電源設備的過載、欠電壓、短路,也可用來保護電動機的過載、欠電壓和短路或用於660V的配電網絡中,用作上述保護。此外斷路器還可以用於1140V的配電網絡,作上述保護。
斷路器(限流斷路器)除固定式結構外,還具有抽屜式結構,在正常條件下可作為線路的不頻繁轉換和電動機的不頻繁起動之用。由於斷路器具有二段或三段保護特性,可以對電網作選擇性保護。抽屜式斷路器(抽屜式限流斷路器)在主回路和二次回路中均采用了插入式結構,省略了固定式所必須的隔離器,做到一機二用,提高了使用的經濟性,同時給操作與維護帶 來了很大的方便,增加了安全性、可靠性。特別是本抽屜座的主回路觸刀座,可與NT3型熔斷器觸刀座通用,這樣在應急狀態下可直接插入熔斷器供電。
限流斷路器由於具有限流特性,特別適用於可能出現大短路電流的網絡。
斷路器按GB14048.2設計,製造與檢驗。
