雙電源自動轉(zhuǎn)換開關(guān)是對兩路電源進(jìn)行切換,分常用電源和備用電源,當(dāng)常用電源斷電后備用電源供電,常用電源來電后恢復(fù)到常用供電(這就是自投自復(fù),常用電源優(yōu)先供電的原則) 如特殊情況不需要自動切換,也可以自行設(shè)置到手動切換(一般型具有手動/自動兩用,任意調(diào)節(jié))。再者,其內(nèi)部安裝有一種由微處理器控制,用于電網(wǎng)系統(tǒng)中網(wǎng)電與網(wǎng)電或網(wǎng)電與發(fā)電機(jī)電源啟動切換的裝置,可使電源連續(xù)源供電,當(dāng)常用電突然故障或停電時,通過雙電源切換開關(guān),自動投入到備用電源上,使設(shè)備仍能正常運(yùn)行。

雙電源
雙電源自動切換開關(guān)是指:一種由微處理器控制,用于電網(wǎng)系統(tǒng)中網(wǎng)電與網(wǎng)電或網(wǎng)電與發(fā)電機(jī)電源啟動切換的裝置,可使電源連續(xù)源供電。系列雙電源,當(dāng)常用電突然故障或停電時,通過雙電源切換開關(guān),自動投入到備用電源上,(小負(fù)荷下備用電源也可由發(fā)電機(jī)供電,)使設(shè)備仍能正常運(yùn)行。常見的是電梯、消防、監(jiān)控上、照明等。
開關(guān)
開關(guān)是指一個可以使電路開路、使電流中斷或使其流到其他電路的電子元件。開關(guān)的原理是接點(diǎn)的“閉合”(closed)表示電子接點(diǎn)導(dǎo)通,允許電流流過;“開路”(open)表示電子接點(diǎn)不導(dǎo)通形成開路,不允許電流流過。 按照用途分為波動開關(guān)、波段開關(guān)、錄放開關(guān)、電源開關(guān)、預(yù)選開關(guān)、限位開關(guān)等。按照結(jié)構(gòu)分為微動開關(guān)、船型開關(guān)、鈕子開關(guān)、撥動開關(guān)等。
