    CRW2智能型萬能式斷路器 結(jié)構(gòu)特征
    本斷路器分固定式和抽屜式兩種結(jié)構(gòu);?斷路器為立體布置,由側(cè)板、橫梁組成框架,每相觸頭系統(tǒng)安裝在框架上,上面裝滅弧室。操作機(jī)構(gòu)在斷路器右前方,通過主軸與觸頭系統(tǒng)相連。電動操作機(jī)構(gòu)通過方軸與機(jī)構(gòu)連成一體裝于斷路器下部,作為斷路器的儲能或直接閉合之用,儲能后閉合由釋能電磁鐵完成。在左側(cè)板上方裝有防回跳機(jī)構(gòu),以防止斷路器在分?jǐn)鄷r彈跳。欠電壓和分勵脫扣器經(jīng)過放大機(jī)構(gòu)與脫扣半軸相連,以減少斷路器的脫扣力。面板上有顯示斷路器工作位置的指示牌"I""O"及智能控制器,手動操作手柄供手動儲能使用(僅指2000殼架)。
    抽屜式斷路器由斷路器本體與抽屜座組成,通過斷路器本體上的母線與抽屜座上橋型觸頭的插座接通主回路,具有機(jī)械聯(lián)鎖裝置,能保證斷路器在斷開狀態(tài)下進(jìn)行主回路轉(zhuǎn)換。
    控制器由互感器組件、電子部件及執(zhí)行元件等三部分組成,互感器組件由空心互感器和速飽和互感器組成,直接套在母線上,二次引出線與控制器相連。
