摘要
工厂10KV配电所是电力系统的一个重要组成部分,由电气设备及配电网络按一定的接线方式所构成,他从电力系统取得电能,通过其变换、分配、输送与保护等功能,然后将电能安全、可靠、经济的输送到每一个用电设备的转设场所。配电所涉及方面很多,需要考虑的问题多,分析配电所担负的任务及用户负荷等情况,选择所址,利用用户数据进行负荷计算,确定用户无功功率补偿装置。同时进行各种变压器的选择,从而确定配电所的接线方式,再进行短路电流计算,选择送配电网络及导线,进行短路电流计算,选择配电所高低压电气设备。
本配电所的初步设计包括了:
(1)功率补偿
(2)变压器确定
(3)系统接线方案选择
(4)短路电流的计算
(5)继电保护的选择与整定
(6)防雷与接地保护等内容
关键词:配电所;主接线;继电保护
Abstract
10KV substation power plant is an important part of the system, the electrical equipment and wiring work according to a certain way position, he obtained power from the power system, through its transformation, distribution, transportation and protection functions, then energy safe, reliable, economical transportation to each place setting to switch electrical equipment. Distribution involves many aspects, many problems need to be considered, analysis of distribution of the tasks and user load, etc., select the site, the use of user data for load calculation to determine the reactive pensation device users. While the choice of a variety of transformers in order to determine the distribution of the wiring, then short-circuit current calculation, select the electric Transmission and work and conductors, the short-circuit current calculation, select the high and low voltage electrical distribution equipment.
The distribution of the preliminary design include:
(1) pensation
(2) to determine the transformer
(3) system wiring scheme selection
(4) short-circuit current calculation
(5) relay selection and tuning
(6), lightning protection and grounding protection, etc.
Keywords: distribution of; main wiring; relay
