FN3負荷開關 FN3-12高壓開關
1、FN3-12、FN3-12R、FN3-12R/S負荷開關系戶內裝置的高壓電器。適用于交流50Hz、6KV或12KV的網絡中,作為開斷和閉合負荷及過荷電流之用,亦可用作開斷和閉合空載長線??蛰d變壓器及電容之開關。帶有RN3型熔斷型的負荷開關(FN3-12、FN3-12R/S)可切斷路器,作保護開關之用。 2、本負荷開關可配用CS3型及CS2型手動操作機構進行操作。 1、FN3-12、FN3-12R、FN3-12R/S Series are used in the network of AC 50Hz、6KV or 12KV for breaking or closing load and over-load current. they are also used in breaking and closing no-loading . The switch or no-load transformer and capacitor with KN3 type fuse box. Can cut off short-circuit for protecting switch. 2、They can be equipped with CS3 type and CS2 type handle operating mechanism. 工作條件 Serviec Condition 1、海拔不超過1000米; 2、周圍空氣溫度不高于+40oC及不低于-10oC; 3、空氣相對濕度不大于90%的戶內場(當溫度為+25); 4、無導電性塵埃的環境中; 5、無破壞金屬和絕緣的腐蝕性氣體的物體; 6、無劇烈震動和沖擊的地方; 7、無燃燒與爆炸危險的環境中。 1 、The altitude does not exceed 1000m. 2、The ambient air temperatrue : Max:+40oC.
