摘要:本次設(shè)計(jì)的題目是響水縣黃圩中學(xué)供配電系統(tǒng)設(shè)計(jì)，該系統(tǒng)是通過(guò)降壓變壓器和10kV的公共電源干線相連向?qū)W校供電，學(xué)校對(duì)供電可靠性的要求很高，因此要嚴(yán)格按照國(guó)標(biāo)規(guī)定以及現(xiàn)代電氣技術(shù)完成該校的供配電系統(tǒng)設(shè)計(jì)。 設(shè)計(jì)包括負(fù)荷計(jì)算、無(wú)功補(bǔ)償、變電所的選定、短路電流計(jì)算、主變壓器的選擇、電氣主接線的設(shè)計(jì)、電器設(shè)備的選擇、繼電保護(hù)以及防雷措施等主要內(nèi)容。其中，主接線是變配電所的主體，對(duì)整個(gè)供配電系統(tǒng)的運(yùn)作有決定性的作用；負(fù)荷計(jì)算采用需要系數(shù)法；采用并聯(lián)電力電容器進(jìn)行無(wú)功功率補(bǔ)償；按照各電氣元件所需的校驗(yàn)項(xiàng)目對(duì)其進(jìn)行校驗(yàn)；繼電保護(hù)主要是對(duì)主變壓器進(jìn)行整定計(jì)算。 關(guān)鍵詞 供配電系統(tǒng)；變電所；設(shè)計(jì)
Abstract:The design topic is the power supply and distribution system for Huangwei middle school of Xiangshui county,the system is connected with the public line of 10kV through step-down transformer and distribute electrical power to the school.The school’s demand of reliability of power supply is high,so we will strictly according to the regulation of the national standard and the modern electrical technology to complete the design of supply and distribution system. The design includes load calculation,reactive power compensation,the choice of electric power substation ,short-circuit current calculation,the choice of the main transformer,the design of main electrical wiring,the selection of electrical equipment , relay protection and lightning protection measures.Among them,main electrical wiring is main body of substation and distribution station,it has a decisive role on the operation of power supply and distribution system. Load calculation using need coefficient method,at the same time using parallel power capacitor for reactive power compensation.Electrical components according to the needs of the project check.And relay protection is the setting calculation of the main transformer. Keywords power supply and distribution electric power substation design |
