6kv系統(tǒng)電壓等級(jí)對(duì)應(yīng)7.2kv開(kāi)關(guān)柜(配電開(kāi)關(guān)柜 ),相應(yīng)的10kv-->12kv20kv-->24kv35kv-->40.5設(shè)備額定電壓未系統(tǒng)運(yùn)行電壓均方根值,大概1.2倍必須要大,不能正合適,要有余量。淄博ggd低壓開(kāi)關(guān)柜(雙層開(kāi)關(guān)柜 )插拔式
2、為什么10KV的電壓等級(jí)選擇KYN28-12的柜型，淄博ggd低壓抽屜柜35KV的選擇JYN-40.5的柜型？那6KV選多大？7.2KV么？
高（中）壓開(kāi)關(guān)柜(西門(mén)子35KV開(kāi)關(guān)柜 )的額定電壓按GB/T11022-1999標(biāo)準(zhǔn)
4.1 額定電壓（Ur）5]
額定電壓為開(kāi)關(guān)設(shè)備和控制設(shè)備所在系統(tǒng)的最高電壓上限。淄博ggd低壓開(kāi)關(guān)柜(小型化開(kāi)關(guān)柜 )單元數(shù)
額定電壓的標(biāo)準(zhǔn)值如下：
4.1.1 范圍I
額定電壓252kV及以下：3.6，淄博gcs開(kāi)關(guān)柜(直流開(kāi)關(guān)柜 )7.2，淄博gck開(kāi)關(guān)柜(中低壓開(kāi)關(guān)柜 )12，淄博10kv高壓開(kāi)關(guān)柜(中置開(kāi)關(guān)柜 )型號(hào)24，淄博10kv高壓開(kāi)關(guān)柜(繞線電機(jī)開(kāi)關(guān)柜 )結(jié)構(gòu)40.5，淄博10kv高壓開(kāi)關(guān)柜(鼠籠電機(jī)開(kāi)關(guān)柜 )柜后放電72.5，淄博10kv高壓開(kāi)關(guān)柜(源創(chuàng)開(kāi)關(guān)柜 )故障126，淄博10kv高壓開(kāi)關(guān)柜(五防開(kāi)關(guān)柜 )設(shè)計(jì)252kV。淄博ggd低壓抽屜柜
4.1.2 范圍Ⅱ
額定電壓252kV以上：363，淄博10kv高壓開(kāi)關(guān)柜(一體化開(kāi)關(guān)柜 )故障停電550，淄博10kv高壓開(kāi)關(guān)柜(源創(chuàng)生產(chǎn)的開(kāi)關(guān)柜 )母線安裝方案800kV。淄博gcs開(kāi)關(guān)柜(高低壓無(wú)線開(kāi)關(guān)柜 )
12kv是設(shè)備額定電壓，淄博10kv高壓開(kāi)關(guān)柜(可遠(yuǎn)程控制的開(kāi)關(guān)柜 )主母線多大10kv是系統(tǒng)額定電壓，淄博10kv高壓開(kāi)關(guān)柜(山東開(kāi)關(guān)柜 )原理圖7.2kv和6kv也是如此。淄博gck開(kāi)關(guān)柜(濰坊開(kāi)關(guān)柜 )
