摘 要
变电所是电力系统的枢纽环节，由变压器，母线和开关设备等电气设备按一定的结线方式所构成，他从电力系统取得电能，进行电压变换和分配，然后将电能安全、可靠、合理的供给不同的用电场所和电力设备。变电所设计的主要任务是根据变电所担负的任务及用户负荷情况等，选择所址，对用户的负荷进行统计、分析计算，确定用户无功功率补偿装置。进行变压器选择，确定变电站的结线方式，进行短路电流计算，选择变配电开关设备，绘制变电所平面布置图。本变电所的初步设计包括：总体方案的确定；负荷分析；短路电流的计算；配电系统设计与系统接线方案选择；变电所高压进线、一次设备和低压出线的选择；防雷与接地保护等容。 WIN IN CHINA【关 键词】： 变电所设计； 负荷的计算； 变压器选择； 开关设备选择； 线路设计； 防雷设计。公路超限检测站管理办法>刘荃
Abstract
河北华裕家禽育种有限公司The transformer substation is the pivot links of the power system, by the voltage transforme
r, electric equipment such as bus bar and switchgear form according to certain knot line way, he make electric energy from power system, carry on voltage vary and assign, electric energy safe, reliable, reasonable supply different power consuming place and electric apparatus. The main task of substation design is based on the tasks and substation loads and other users, select the address of the user's load of statistics, analysis and calculation to determine the reactive power compensation device users. Transformer selection, determine the end-line substation, the short-circuit current calculation, select the power distribution switchgear, substation floor plan drawing. The preliminary design of the substation, including: the determination of the overall program; load analysis; short-circuit current calculation; distribution system design and system wiring scheme selection; substation high voltage into the line, a selection of equipment and low-voltage outlet; lightning protection and ground protection and so on.
【Keywords】: substation design; load calculation; transformer selection; switching equipment selection; circuit design; lightning protection design.
