摘要:隨著經(jīng)濟(jì)的迅速發(fā)展，科學(xué)技術(shù)的不斷進(jìn)步促使社會(huì)中各行各業(yè)都在不斷地發(fā)展壯大，電能已成為工業(yè)生產(chǎn)的主要能源和動(dòng)力，做好工廠供電設(shè)計(jì)對(duì)于發(fā)展工業(yè)生產(chǎn)、實(shí)現(xiàn)工業(yè)現(xiàn)代化，具有十分重要的意義。本化纖廠35kv降壓變電所電氣設(shè)計(jì)，一是要能夠滿足化纖廠的工業(yè)生產(chǎn)和化纖廠生活用電的需要，二是要保證為本化纖廠安全，可靠的供電，技術(shù)先進(jìn)和經(jīng)濟(jì)合理，并且同時(shí)要做好一些節(jié)能措施。 這次的設(shè)計(jì)題目某化纖廠35kv降壓變電所電氣設(shè)計(jì)。此設(shè)計(jì)根據(jù)某化纖廠實(shí)際的供電電源及實(shí)際用電負(fù)荷，并且適當(dāng)?shù)目紤]到本廠未來(lái)生產(chǎn)一定的發(fā)展空間，同時(shí)要滿足工廠供電的基本要求，首先，進(jìn)行了對(duì)各車(chē)間計(jì)算負(fù)荷及無(wú)功補(bǔ)償；確定出了各變電所的位置及個(gè)變電所變壓器臺(tái)數(shù)、容量和型號(hào)。其次，進(jìn)行了短路電流的計(jì)算，選擇和校驗(yàn)了各線路導(dǎo)線截面和變電所高低壓設(shè)備選擇和校驗(yàn)。最后，對(duì)各車(chē)間變電所及總降變電所進(jìn)行繼電保護(hù)整定計(jì)算及配置，且配置接地裝置及防雷保護(hù)裝置，同時(shí)繪制出設(shè)計(jì)的電氣設(shè)計(jì)圖樣，完成了化纖廠降壓變電所電氣的設(shè)計(jì)。 關(guān)鍵詞: 負(fù)荷計(jì)算; 短路電流計(jì)算; 無(wú)功補(bǔ)償; 變壓器選擇; 接地裝置
ABSTRACT:With the rapid development of economy, the constant progress of science and technology society in all walks of life is in constant development, electricity has become the main energy and power of industrial production, completes the factory power supply design for the development of industrial production, to achieve industrial modernization, have very important significance. This chemical fiber factory of 35 kv step-down substation electrical design, firstly can be able to meet the industrial production and the chemical fiber factory of life needs,Secondly to ensure safe and reliable power supply as well as the advanced technology and reasonable economy, and energy saving measures. This design topic is a chemical fiber factory 35 kv step-down substation electrical design characteristic.This design according to the actual power supply of a certain characteristic and actual electricity load, And due consideration to the future development space in our chemical fiber factory , to meet the basic requirement of the factory power supply at the same time, First of all, the computational load of each workshop and reactive power compensation; determine the location of each substation and a substation transformer sets, capacity and model.the computational load of each workshop and reactive power compensation;The location of the substation and the number, the capacity and the type of the transformer are confirmed, Secondly, for the calculation of short-circuit current; Select and check each line section and high and low voltage substation equipment selection and calibration.Finally, the configuration of substation relay protection devices, lightning protection and grounding device, at the same time, draw out the design of the electrical drawings, complete the chemical fiber factory step-down substation electrical design. Keywords: load calculation; Short circuit current calculation; reactive power compensation ; Transformer selection; grounding device |
