摘要
 本設(shè)計(jì)說(shuō)明書(shū)是以德清民樂(lè)小區(qū)的變配電所為主體進(jìn)行設(shè)計(jì)的。通過(guò)對(duì)設(shè)計(jì)原始資料的分析，住宅小區(qū)負(fù)荷的計(jì)算短路計(jì)算，選擇相應(yīng)的主變壓器臺(tái)數(shù)和容量，從而確定其具體的供電系統(tǒng)。再對(duì)其初選的系統(tǒng)進(jìn)行相應(yīng)的短路計(jì)算和高低壓設(shè)備的選擇及校驗(yàn)，選擇和校驗(yàn)高低壓線路。結(jié)合課本的基礎(chǔ)知識(shí)，根據(jù)我國(guó)變配電所的運(yùn)行情況以及各種電氣設(shè)備的標(biāo)準(zhǔn)，進(jìn)行具體的電氣設(shè)備，達(dá)到安全用電和節(jié)約能源的目的，另外得出該住宅小區(qū)供電系統(tǒng)的線路圖。本設(shè)計(jì)嚴(yán)格遵循變電所電氣部分的設(shè)計(jì)原則。
 通過(guò)本次畢業(yè)設(shè)計(jì)，鞏固了供電系統(tǒng)的設(shè)計(jì)，熟練運(yùn)用四年以來(lái)學(xué)過(guò)的知識(shí)，鍛煉并提高了獨(dú)立分析和解決問(wèn)題的能力，也培養(yǎng)了對(duì)大學(xué)四年所學(xué)知識(shí)的綜合應(yīng)用。

Abstract
The design specification is based on folk music Deqing area for the variable distribution of the main design. Through the design analysis of raw data, the calculation of residential quarters load short-circuit calculation, select the appropriate and the number of main transformer capacity, in order to determine the specific power supply system. Primary system and then its corresponding short-circuit calculations and the choice of high and low voltage equipment check, selection and validation of high low-voltage lines. Combined with the basic knowledge of textbooks, according to our country by changing the operation of distribution and a variety of electrical equipment standards, electrical equipment specific to the security of electricity and energy savings, and come to the residential quarters of the line power supply system Fig. Strictly follow the design of electrical substation design principles.
Graduated through the design, the consolidation of the power supply system design, training and increased the independent analysis and problem-solving skills, also trained by four years of university the comprehensive application of knowledge.
