工作原理
當(dāng)常用電源正常,功能鍵置于自動(dòng)檔時(shí),備用斷路器分、常用斷路器合,以保護(hù)常用電源接通負(fù)載。當(dāng)常用電源A一相或三相全部電壓中斷時(shí),ATS將負(fù)載從常用電源轉(zhuǎn)換到備用電源(當(dāng)備用電源有正常電壓時(shí)),并在常用電源恢復(fù)至正常時(shí),又將備用電源轉(zhuǎn)換至常用電源。
故障分析與排除
當(dāng)處于自動(dòng)控制狀態(tài)下供電電源發(fā)生改變時(shí),電操機(jī)構(gòu)不動(dòng)作,即小型斷路器不能合閘或分閘,此時(shí)應(yīng)先檢查:
(1)電網(wǎng)是否都停電;
(2)接線有否脫落;
(3)產(chǎn)品本身的保險(xiǎn)絲是否燒斷。如果任一斷路器前端有電,而接線又都正確,保險(xiǎn)絲也完好,但仍不能合閘或分閘,此時(shí)應(yīng)請(qǐng)專業(yè)人員維修或與制造廠解決。
A型控制器:置于轉(zhuǎn)換開(kāi)關(guān)內(nèi)部,監(jiān)測(cè)兩路電源電壓,控制電源轉(zhuǎn)換動(dòng)作。
CB級(jí):是指轉(zhuǎn)換開(kāi)關(guān)主體如符合GB14048.2、GB14048.9,這些產(chǎn)品本身具有短路、過(guò)載保護(hù)功能,因此雙電源也具有這些功能;而主體開(kāi)關(guān)符合GB14048.3,本身產(chǎn)品不具有類似保護(hù)功能,屬于PC級(jí);主體開(kāi)關(guān)符合GB14048.4的則屬于CC級(jí)。
R:自投自負(fù)(意思是當(dāng)常用電源出現(xiàn)異常后,雙電源會(huì)轉(zhuǎn)換至備用電源,而當(dāng)常用電源恢復(fù)后,則轉(zhuǎn)換至常用電源,反之則屬于自投不自復(fù))。
