SHR-600/335,SHR-600/435 負(fù)荷鐵殼開關(guān)
1.SHR系列熔斷器式開關(guān),適用于交流50~60Hz,額定絕緣電壓至500V,額定工作電壓415V(包括380V)有,約定發(fā)熱電流至400安培的電路中,作為手動不頻繁地接通與分?jǐn)嘭?fù)載電路和線路的過載與短路保護(hù)之用。由于裝有中性接線柱,熔斷器式開關(guān)也可作為一般照明等回路的控制開關(guān)之用。 高短路電流的配電回路和電動機(jī)回路作為電源隔離開關(guān)、負(fù)荷開關(guān)和應(yīng)急開關(guān)、供電路通斷及保護(hù)之用。
2.SHR負(fù)荷開關(guān)箱適用于下列工作條件:
1)海拔不高于2000米
2)周圍環(huán)境溫度不高于+40攝氏度不低于-5攝氏度
3)空氣相對濕度不大于90%(+25℃)
4)垂直安裝于無強(qiáng)烈振動和沖擊的場合
5)在無爆炸氣體和腐蝕氣體的場合
2.SHR負(fù)荷開關(guān)箱分類和型式
1)按約定發(fā)熱電流分有100,200,315,400安培四個等級
2)按結(jié)構(gòu)型式分有開啟式和封閉式兩種
3)按極數(shù)分有3極帶中性接線柱和3極不帶中性接線柱,4極三種
3.SHR負(fù)荷開關(guān)箱結(jié)構(gòu)特征
熔斷器式開關(guān)主要由觸頭滅弧系統(tǒng),熔斷器,操作機(jī)構(gòu)和外殼四個部分組成。滅弧室由耐弧塑料壓制,機(jī)構(gòu)簡單,便于拆裝。觸頭系統(tǒng)采用雙斷點(diǎn)直動式長形觸頭型式,動觸點(diǎn)是以有填料封閉管式熔斷器為橋臂的雙斷點(diǎn)U型觸頭,長形觸頭有較高的電動穩(wěn)定性,雙斷點(diǎn)有較高的分?jǐn)嗄芰ΑS刑盍戏忾]管式熔斷器的極限分?jǐn)嗄芰_(dá)50千安,可以滿足一般電網(wǎng)的要求。操作機(jī)構(gòu)采用單桿抽拉式結(jié)構(gòu)和彈簧儲能原理。用同一彈簧執(zhí)行開關(guān)接通分?jǐn)嗟臋C(jī)能,保證開關(guān)能可靠的接通和分?jǐn)?,并有明顯的通斷標(biāo)志。抽拉式操作手柄,在開關(guān)接通或分?jǐn)嘁院?,可以推入開關(guān)外殼內(nèi),外形美觀,開關(guān)蓋殼裝有連鎖裝置,保證在蓋子打開后開關(guān)不能接通及開關(guān)接通后蓋子不能打開。
