在電力系統(tǒng)中，l0kV 高壓開關(guān)柜的應(yīng)用極其廣泛。其中 KYN28-12 金屬鎧裝移開式
開關(guān)設(shè)備更是被大量用于電力系統(tǒng)中。但由于用戶的需求各不相同，作為開關(guān)柜制造廠
家的設(shè)計人員，我們不得不根據(jù)用戶的需求，為用戶量身定做。這就要求我們必須真正
深刻地理解相關(guān)的國家標(biāo)準(zhǔn)、部頒標(biāo)準(zhǔn)和標(biāo)準(zhǔn)柜型的設(shè)計要求，以及對KYN28-12金屬鎧
裝移開式開關(guān)柜有一個比較全面的了解：包括KYN28-12開關(guān)柜的結(jié)構(gòu)、配置、元器件選
型、二次原理、安裝維護(hù)、賣點、同其他同行業(yè)廠家的對比等。以便能設(shè)計出更好的產(chǎn)
品，在技術(shù)交流過程中能更好地介紹公司產(chǎn)品。本產(chǎn)品技術(shù)說明書從結(jié)構(gòu)、聯(lián)鎖、元件
等方面詳細(xì)介紹了 KYN28-12 開關(guān)柜，希望能對大家對 KYN28-12 開關(guān)柜的設(shè)計及技術(shù)交
