根據(jù)其性能和特點(diǎn),將自動(dòng)雙電源轉(zhuǎn)換開(kāi)關(guān)分為PC級(jí)和CB級(jí)。

1) PC 級(jí): PC 級(jí)雙電源自動(dòng)切換開(kāi)關(guān)可以開(kāi)啟、承受,但不能用于斷開(kāi)短路電流的雙電源,如果選擇雙電源不具備過(guò)電流釋放的負(fù)載開(kāi)關(guān)作為執(zhí)行機(jī)構(gòu),則 PC 級(jí)自動(dòng)切換開(kāi)關(guān)具有保護(hù)功能,但它具有較高的耐受性和開(kāi)啟能力,可以保證開(kāi)關(guān)本身的安全,不會(huì)因過(guò)載或短路而發(fā)生故障和損壞,在這種情況下保證可靠的開(kāi)通電路。
2)CB級(jí):CB級(jí)雙電源自動(dòng)轉(zhuǎn)換開(kāi)關(guān)配有過(guò)電流脫扣器雙電源,其主觸頭可接通并用于開(kāi)斷短路電流。雙電源應(yīng)選擇僅短路電流脫扣器的斷路器作為其執(zhí)行機(jī)構(gòu),該斷路器屬于CB級(jí)自動(dòng)轉(zhuǎn)換開(kāi)關(guān),具有選擇性保護(hù)功能,可為下層負(fù)荷和電纜提供短路保護(hù)。它的連接和分?jǐn)嗄芰Ρ冉佑|器和繼電器等其他元件大得多。。

2、STS靜態(tài)數(shù)據(jù)轉(zhuǎn)換控制開(kāi)關(guān)

STS(靜態(tài)轉(zhuǎn)換開(kāi)關(guān)),靜態(tài)開(kāi)關(guān),也稱為靜態(tài)轉(zhuǎn)換開(kāi)關(guān),是用于選擇兩個(gè)電源的自動(dòng)切換系統(tǒng)。 如果電路發(fā)生故障,STS自動(dòng)切換到電路向負(fù)載供電(假設(shè)電路正常且與電路基本同步);如果電路發(fā)生故障,STS自動(dòng)切換到電路向負(fù)載供電(假設(shè)電路正常且與電路基本同步),適用于UPS-UPS、UPS發(fā)電機(jī), UPS-mains,對(duì)于任何兩個(gè)電源(如市政電源)的不間斷電源轉(zhuǎn)換,上述電源之間需要同步裝置,以確保兩個(gè)電源的基本同步,否則STS不能切換。
