雙電源自動轉(zhuǎn)換
 
◆采用雙列復(fù)合式觸頭、橫接式機(jī)構(gòu)、微電機(jī)預(yù)儲能及
 
微電子控制 技術(shù)，基本實(shí)現(xiàn)零飛?。o滅弧罩）
 
◆采用可靠的機(jī)械聯(lián)鎖和電氣聯(lián)鎖技術(shù)
 
◆采用過零位技術(shù)
 
◆具有明顯通斷位置指示、掛鎖功能，可靠實(shí)現(xiàn)電源與負(fù)載間的隔離 可靠性高，使用壽命8000次以上
 
◆機(jī)電一體設(shè)計(jì)，開關(guān)轉(zhuǎn)換準(zhǔn)確、靈活、可靠 電磁兼容好，抗干擾能力強(qiáng)，對外無干擾，自動化程序高
 
◆全自動型不需外接任何控制元器件 外形美觀、體積小、重量輕 由邏輯控制板，以不同的邏輯來管理直接裝于開關(guān)內(nèi)的電機(jī)，變速箱的動行操作來保證開關(guān)的位置。
 
電機(jī)為聚氯丁橡膠絕緣濕熱型電機(jī)裝有安全裝置，在超出110℃濕度和過電流狀態(tài)時跳閘。
 
在故障消失后即自動投入工作，可逆減速齒輪采用直齒齒輪。

①切除市電供電各斷路器(包括配電室控制柜各斷路器，雙電源切換箱市供電斷電器)，拉開雙投防倒送開關(guān)至自備電源一側(cè)，保持雙電源切換箱內(nèi)自備電供電斷路器處于斷開狀態(tài)。
 
②啟動備用電源(柴油發(fā)電機(jī)組)，待機(jī)組運(yùn)轉(zhuǎn)正常時，順序閉合發(fā)電機(jī)空氣開關(guān)、自備電源控制柜內(nèi)各斷路器。
 
③逐個閉合電源切換箱內(nèi)各備用電源斷路器，向各負(fù)載送電。
 
④備用電源運(yùn)行期間，操作值班人員不得離開發(fā)電機(jī)組，并根據(jù)負(fù)荷的變化及時調(diào)整電壓、廠頻率等，發(fā)現(xiàn)異常及時處理。
 
2、市電恢復(fù)供電時，應(yīng)及時做好電源轉(zhuǎn)換工作，切斷備用電源，恢復(fù)市電供電。

步驟：

①按順序逐個斷開自備電源各斷路器，順序是：雙電源切換箱自備電源斷路器→自備電源配電柜各斷路器→發(fā)電機(jī)總開關(guān)→將雙投開關(guān)撥至市電供電一側(cè)。
 
②按柴油機(jī)停機(jī)步驟停機(jī)。
 
③按順序，從市電供電總開關(guān)至各分路開關(guān)逐個閉合各斷路器，將雙電源切換箱自市電供電斷路器置于閉合位置。
 
3、檢查各儀表及指示燈指示是否正常，啟動變壓器內(nèi)冷卻風(fēng)扇。
