1、電網(wǎng)電壓等級(jí)對(duì)應(yīng)的中壓開(kāi)關(guān)柜(鎧裝開(kāi)關(guān)柜 )電壓等級(jí)各是多少,青島gck開(kāi)關(guān)柜(配電開(kāi)關(guān)柜 )為什么開(kāi)關(guān)柜(雙層開(kāi)關(guān)柜 )的電壓要比對(duì)應(yīng)的電網(wǎng)電壓高(如35KV電網(wǎng)對(duì)應(yīng)40.5KV開(kāi)關(guān)柜(西門(mén)子35KV開(kāi)關(guān)柜 )),是如何計(jì)算出來(lái)的,青島10kv高壓開(kāi)關(guān)柜(小型化開(kāi)關(guān)柜 )型號(hào)有沒(méi)有相關(guān)標(biāo)準(zhǔn)要求等規(guī)范(如國(guó)標(biāo)等)?
6kv系統(tǒng)電壓等級(jí)對(duì)應(yīng)7.2kv開(kāi)關(guān)柜(直流開(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。青島gck開(kāi)關(guān)柜(中低壓開(kāi)關(guān)柜 )
2、為什么10KV的電壓等級(jí)選擇KYN28-12的柜型,青島10kv高壓開(kāi)關(guān)柜(中置開(kāi)關(guān)柜 )結(jié)構(gòu)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(繞線電機(jī)開(kāi)關(guān)柜 )的額定電壓按GB/T11022-1999標(biāo)準(zhǔn)
