内容简介：

摘 要根据我国能源利用情况，供电设计的原则要求，以及化工厂的生产程度反映在电气方面的工艺过程有较强的供电连续性等特点。First，对全厂的负荷进行系统计算，为确定供电系统的电力变压器、各种开关电器的容量、电力线路的截面和变电所的所址等提供依据。并且对其进行无功补偿，以减少变压器、电力线路、开关设备的功率损耗，从而减少电器元件的规格，降低它的功率损耗和电压损耗，减少投资；Second,根据本厂的实际情况和经济技术比较电力变压器，确定变电所的所址、类型以及其主接线方案；Third按符合情况系统地对厂区进行设计，为了校验一次设备的短路稳定度，开关电器的断流能力及电流保护装置的灵敏度，整定电流速断保护装置的动作电流，进行短路电流的计算，进而选择了电力线路和高低压电气设备；End，确定全厂配电系统的防雷接地系统设计。 According to the situation of utilization of energy of our country, principle designed to supply power require and production degree of chemical plant reflect in electric craft course of respect having stronger power supply continuity ,etc. characteristicking.First，Calculate the system to the load of the the whole factory, for confirm electric voltage transformer , various kinds of of electric power system turn on or off capacity of electric apparatus , electric section of circuit and transformer substation location ,etc. offer the basis. Is it have work compensate to go on to it, in order to reduce voltage transformer , electric circuit , power of the switchgear loss, reduce specification , electric apparatus of component , reduce power of it loss and voltage loss, reduce investment. Second,compare with economic technology the electric voltage transformer according to actual conditions of our factory, confirm the location , type and its main wiring scheme of the transformer substation; Third, According to accord with situation is it design to go on to factory systematically , for check-up one short circuit stability degree of equipment, turn on or off the blanking ability and sensitivity of the electric current protector of the electric apparatus, exactly fix the movement electric current of the broken protector of speed of the electric current, is it short out calculation of electric current to go on , choose electric circuit and high or low prices pigeonhole electric equipment; End，Confirm the whole factory dyke thunder earth , distribution of system design systematically.关键词：电力负荷、功率因数、变电所、变压器、主接线方案、短路电流、配电系统、防雷、接地 目 录第1章 概述1第2章 设计条件22.1 课题名称22.2 任务与要求22.3 供用电协议22.4 负荷性质32.5 气象及地区资料32.6 主要设计任务32.7 设计成品要求4第3章 全厂负荷分析和计算43.1 工厂电力负荷的分级及对供电电源的要求 43.2 计算负荷 53.3 无功负荷的分析、计算与补偿 223.4 全厂负荷计算表 27第4章 10/0.4/0.23KV变电所所址型式确定294.1 变配电所所址选择294.2 总体布置33第5章 变压器台数及容量的选择365.1 变压器台数的确定365.2 主变压器容量的确定365.3 电力变压器的选择43第6章 短路电流计算6.1 短路的原因、后果及其形式466.2 短路计算47第7章 变电所主接线方案经济技术比较和确定7.1 概述557.2 变配电所主接线的选择56第8章 全厂配电系统设计 628.1 低压电力系统628.2.2 工厂电力线路结构、敷设 668.3 导线和电缆截面的选择与校验67第9章 变电所主要电气设备的选择与校验9.1 配电屏类型的确定及一些参数799.2 低压配电屏
