1、摘要在快速發(fā)展的當(dāng)今世界，我們?cè)絹碓诫x不開電能，電能作為所有能源中最重要的一種，它關(guān)系著整個(gè)國家乃至世界的發(fā)展與穩(wěn)定。在整個(gè)電力系統(tǒng)中供配電能成為了電氣設(shè)計(jì)的一個(gè)重要的環(huán)節(jié)。在滿足其安全、可靠、優(yōu)質(zhì)、經(jīng)濟(jì)等基本條件的前提下才能更好地為國民經(jīng)濟(jì)服務(wù)，推動(dòng)社會(huì)發(fā)展。只有好的供電配電環(huán)節(jié)，才能造就高效率的生產(chǎn)和高品質(zhì)的生活。本次設(shè)計(jì)的是職業(yè)技術(shù)學(xué)院10kV配電室。配電室占地約120平方米，高壓側(cè)為10kV，低壓側(cè)為0.4kV，設(shè)有值班室和工具間。配電室主接線采用單母線分段接線方式，低壓配電系統(tǒng)采用TN-S接線方式。本次設(shè)計(jì)任務(wù)包括：負(fù)荷統(tǒng)計(jì)、容量計(jì)算、無功補(bǔ)償計(jì)算、短路電流計(jì)算、設(shè)備
2、選型、防雷接地等。負(fù)荷計(jì)算采用的是需要系數(shù)法，導(dǎo)線截面按發(fā)熱條件進(jìn)行選擇，并按熱穩(wěn)定條件進(jìn)行校驗(yàn)。開關(guān)柜按照正常工作條件進(jìn)行選擇。設(shè)計(jì)過程中，通過參閱相關(guān)的供配電系統(tǒng)設(shè)計(jì)、建筑電氣設(shè)計(jì)等相關(guān)的規(guī)范和設(shè)計(jì)手冊(cè)，完成了對(duì)該校供配電系統(tǒng)的初步設(shè)計(jì)，同時(shí)也提高了我們獨(dú)立分析和解決電氣設(shè)計(jì)問題的能力。本設(shè)計(jì)按照國家相關(guān)設(shè)計(jì)標(biāo)準(zhǔn)規(guī)范要求，合理選擇用電設(shè)備，能基本滿足使用要求。關(guān)鍵詞：10kV配電室；配電系統(tǒng)；負(fù)荷計(jì)算；電氣設(shè)計(jì)AbstractIntoday'sworldofrapiddevelopment,moreandmorewecannotdowithoutelectricity,el
