[毕业设计精品]工厂供配电

前言众所周知，电能是现代工业生产的主要，电能既易于由其他形式的能量以供应用。电能的输送和分配既简单经济，又便于控制调节测量，有利于实现生产过程自动化。而工厂供电就是指工厂所需要电能的供应和分配，工厂供电设计要达到为工业生产服务，保障工厂生产和生活用电的需要，并做好节能工作，就必须做到安全可靠优质经济。工厂供电课程设计是继工厂供电课程后的一个重要性的实践性教学环节，也是整个教学过程中不可缺少的重要组成部分。通过该课程设计可以巩固本课程理论知识，了解变电所设计的基本方法和变电所电能分配的各种实际问题，从而培G1871G10432G12447分G7524和解G1927实际工程G6228G7427问题的能G2159，G2528G7114G4557电G2159工业的有G1863G6931G12586G451方G19036G451G6228G7427G16280程有一G4462的了解，G3324计G12651G13484G3282G451G13546G2507G451设计G16840G7138G1082G12573方G19766G5483到G16769G13463，为G1182后的学G1076G451工作G3892G4462G14403好的基G11796。本G8437课程设计是G4557G7588电G7438制作G5647厂G19489G2399变电所G17839G15904电G8680设计，G3324设计中G7693G6466该厂所能G2474G5483的电G9316G2462用电G17139G14667的实际G5785G1929，并G13783G15397工厂以后的G2469G4649，G6365G10043可靠G451G6228G7427G1820G17839G451经济G2524理的要G8726G4448成了以G991G983部分G1881G4493G3G708G20G709G3该厂G17139G14667计G12651和G7092G2163G2163G10587计G12651G2462G15929G1619方G7708的G17885G4462G727G3G708G21G709G3变电所主变G2399G3132G2500G6980和G4493量的G17885G6333G727G3G3G708G22G709G3变电所G1313G13634和形式的G17885G6333G727G3G708G23G709G3主G6521G13459方G7708的G17885G6333G727G3G708G24G709G3G20652G1314G2399电G2159G13605G4560G13459的G17885G6333G727G3G708G25G709G3G11713G17347电G8981的计G12651G727G3G708G26G709G3变电所一G8437设G3803的G17885G6333G994G7669G20576G727G3G708G27G709G3变电所G1120G8437G3250G17347方G7708G17885G6333G2462继电保G6264的整G4462G727G3G708G28G709G3G19462G19659和G6521G3332G16025G13634的G11842G4462G727G3后有G8504G8437课程设计的G5527G5483G1319G1262和G2454G13783G7003G10498，并G19480G3282G13452G21G5364G708以G19480G3282形式G13485出G709，分别是G19480G3282一变电所平G19766G3282，G19480G3282G1120变电所电G8680主G6521G13459G3282。G3电G8680设计有很强的实践性，作者初G8437G6521触这方G19766的设计，而且知识掌握的深度和广度有限，设计中难免存G3324不G4448善的G3332方，敬请老师和读者批评斧正G3G3G3G3G3G3G3第一章设计任务11设计要求要G7693G6466本厂所能G2474G5483的电G9316G2462用电G17139G14667的实际G5785G1929，并适当G13783G15397到工厂的G2469G4649，G6365G10043安全可靠，G6228G7427G1820G17839，经济G2524理的要G8726，G11842G4462变电所的G1313G13634G994形式，G11842G4462主变G2399G3132的G2500G6980和分变G2399G3132的G2500G6980，G4493量G2462类型。G17885G6333变电所主要G6521G13459方G7708G2462G20652G1314G2399设G3803G17839G451出G13459。G11842G4462G1120G8437G3250G17347方G7708，G17885G6333整G4462继电G3132保G6264G16025G13634，G11842G4462G19462G19659和G6521G3332保G6264G16025G13634，G708横G13459部分G1881G4493本G8437课程设计不作具G1319要G8726G709最后G6365要G8726写出设计G16840G7138G1082，G13484制设计G3282样。12设计依据121工厂总平面图G3G3G3122工厂负荷情况1G451工厂G17139G14667G5785G1929本G5647厂多G6980分厂为两班制，年最大G17139G14667小G7114G6980为6800小G7114，日最大符G2524持续G7114间为8小G7114。除特种电G7438分厂G451试G20576站为一级G17139G14667，铸造分厂G451锅炉房为G1120级G17139G14667外，其余为三级G17139G14667。本G5647厂的G17139G14667统计资料如表所示。2G451供电电G9316G5785G1929G6365G10043该G5647厂G994当G3332供电部门签订的供电用电协议G16280G4462，该厂可以离厂5000米和8000米G70804/KMG709两处的35KV的公用电G9316干G13459上G2474G5483工作电G9316。干G13459首端所G16025设的G20652G2399断G17347G3132的断G8981G4493量为800MVA。该干G13459的走向见G5647厂平G19766G3282。3G451最热月平均最G20652温度为35，年平均温度为18，最热月土壤平均温度为30。G8680象资料概G1929。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第二章负荷计算和无功功率计算21负荷计算的目的及意义G708G20G709G17885G6333电G2159变G2399G3132的G4493量G3G708G21G709G17885G6333电G2159G4560G13459的截G19766G708G13459径大小G709G3G708G22G709G17885G6333电G3132G2462开G1863G4493量和互感G3132的额G4462G2454G6980G3G3G3计G12651G17139G14667是供电设计计G12651的基本依G6466。计G12651G17139G14667G11842G4462G5483是否正G11842G2524理，直G6521影响到电G3132和G4560G13459电缆的G17885G6333是否经济G2524理。如果计G12651G17139G14667G11842G4462G5483过大，将使电G3132和G4560G13459电缆G17885G5483过大，造成投资和有色金属的浪费G727如果计G12651G17139G14667G11842G4462G5483过小，又将使电G3132和G4560G13459电缆处于过G17139G14667G991运G15904，增加电能损耗，产生过热，G4560致绝缘过早老化G10990G14279G10135G9915G5353G17227G9791G9810，G2528样G1262造成G7368大损G3845。由G8504可见，正G11842G11842G4462计G12651G17139G14667G5859G1053重大。22计算负荷的计算公式221单组计算负荷计算公式1G709有G2163计G12651G17139G14667单G1313为KW30PDKEP，DK为需要G13007G69802G709G7092G2163计G12651G17139G14667单G1313为KVA30Q30PTAN3G709A70A71A72A73A74A75单G1313为KVACOSPS30304G709计G12651电G8981N3030U3SI，NU为用电设G3803的而G4462电G2399。5A76A77A781A79A802A79A81A82A83A84A85A86A87DK1A84A8830PEPA89A90A91A92A93A94A84A95A91A96A97A98A99A100A101A102A103A104A84A105A106A107A77A78A108A79A92A93A94A83A84A10930PEP/212多组用电设备计算负荷的计算公式G20G12有G2163计G12651G17139G14667G708单G1313为G46G58G709G3G330PG32IPPK30G3式中IP30是所有设G3803组有G2163计G12651G17139G1466730PG1055和，PK是有G2163G17139G14667G2528G7114G13007G6980，可G2474G19G17G27G24G97G19G17G28G24G3G21G12G7092G2163计G126
