职业技术学院综合楼变电室的设计
摘要:本论文主要论述职业技术学院综合楼变电室的设计。设计的主要内容包括:10/0.4KV变电室主变压器的选择,负荷的计算,无功功率的补偿,电气主接线的设计,短路电流的计算,微机继电保护的设计和防雷保护的设计等。
本变电室的主变压器采用SCB-500KVA干式变压器,变电室的主接线采用有汇流母线的接法,对低压侧负载的计算采用需要系数法,本设计采用并联电容器的方法进行无功功率补偿,计算出短路电流并以此为依据确定电力设备的参数。本设计采用微机进行继电保护,采用避雷器来完成防雷保护。

Abstract:This paper mainly design the institute of technology of profession of substation building room. The design of the main content includes: 10/0.4 KV substation room the choice of main transformer, load calculation, reactive power compensation, the main electrical wiring design, the calculation of short-circuit current, the microcomputer relay protection design and lightning protection design, etc.
The main transformer substation room by SCB-500 KVA transformer, electric room Lord wiring the confluence of the bus shall meet method, the low voltage side of the load calculation need coefficient method, this design USES the parallel capacitor methods of reactive power compensation, and calculates the short-circuit current so as to determine the parameters of the power equipment, and by using the microcomputer relay protection for, and by using the lightning arrester to complete lightning protection.
Key words: the substation the room design; The main electrical wiring; Microcomputer relay protection.
