华北理工大学轻工学院 Qing Gong College North China University of Science and Technology 供配电技术课程设计报告设计(论文)题目:某电缆厂供电系统设计学生姓名: 李大伟郭根劼学号: 201224390522 201224390536 专业班级: 12 级电气 5班学部: 信息科学与技术指导教师: 马亮 2015 年 07月 01日摘要随着科技的不断发展和社会的全面进步,人民生活水平不断提高,电力能源已深入到了人们的日常生活和工作中去,对电力工业的发展极其相关问题的研究层出不穷。基于目前我国电力工业飞速发展的现状,结合新型工厂发展的实际要求,倡导“安全、高效、节能”的方针,集变电、配电、照明、自动控制与调节、建筑防雷与保护、电脑设备管理于一体的现代化工厂供用电系统。本设计在充分调查工厂符合设备的情况下,采用需要系数法计算全厂电力负荷,据此与电业部门签订协议,确定供电等级。按照工厂的实际要求进行系统的无功补偿,确定视在计算负荷,将全厂电力负荷按其工作要求的不同分为不同负荷类别,根据工厂发展和规划要求,选择两台厂用主变压器,互为备用的方式相接,保证供电的可靠性。绘制系统主接线图,优选厂区电气设备,根据发热和稳定性要求进行校验,最后确定防雷保护和接地措施,保证提高用电可靠性和经济运行。关键词: 供电系统,负荷计算,短路计算,变压器,防雷设计 Abstract With constant development ofscience and technology and the progressing inanall-round way ofthe society, the living standards of the people are improving constantly, the electric energy has already got deeply toour daily life and work, the study onextremely relevant problems ofdevelopment ofpower industry emerges inanendless stream . Itisonthe basis ofthe current situation that the power industry ofour country develops atfull speed atpresent tooriginally design, combine the actual demand for development ofnew-type factory, advocate the policy of"safe ,high-efficient ,energy-conservation ",collect the switchyard ,distribution ,illumination ,automatically control and regulate ,the building defend thunder ,protection ,computer equipment control and offer the power consuming system inthe integrative modern chemical plant. Originally design incase offully investigating the factory accords with equipment, itneeds coefficient law tocalculate the whole factory toload electrically toadopt, sign the agreement with electricity industry department inview ofthe above, confirm the grade ofsupplying power. Carry onhaving according toactual demand offactory pensate ,confirm apparent tocalculate load systematic, electric load different todivide different load classification into according to job requirements their the whole factory, develop and isitrequire according tofactory ,
