10KV变电站主接线方案设计和主要电气设备的选择

摘要

课程设计是教学过程中的一个重要环节，通过课程设计可以巩固本课程理论知识，掌握供配电设计的基本方法，通过解决各种实际问题，培养独立分析和解决实际工程技术问题的能力，同时对电力工业的有关政策、方针、技术规程有一定的了解，在计算、绘图、设计说明书等方面得到训练，为今后的工作奠定基础。

本设计可分为九部分：负荷计算和无功功率计算及补偿；变电所位置和形式的选择；变电所主变压器台数和容量及主接线方案的选择；短路电流的计算；变电所一次设备的选择与校验；变电所高、低压线路的选择；变电所二次回路方案选择及继电保护的整定；防雷和接地装置的确定；心得和体会；附参考文献。

另外有设计图纸4张（以附图的形式给出），分别是：附图一《厂区供电线缆规划图》；附图二《变电所平面布置图》；附图三《变电所高压电气主接线图》；附图四《变电所低压电气主接线图》。

由于设计者知识掌握的深度和广度有限，本设计尚有不完善的地方，敬请老师、同学批评指正！关键词：各种计算；变电所的设置；防雷

10KV transformer substation host wiring project design and

main electrical equipment choice

Abstract

The curriculum design is in a teaching process important link, designs through the curriculum may consolidate this curriculum theory knowledge, grasps for the power distribution design essential method, through solves each kind of actual problem, raises the independent analysis and solution actual project technical question ability, simultaneously to the electric power industry related policy, the policy, the technical regulations has certain understanding, in aspects and so on computation, cartography, design instruction booklet is under the training, will lay the foundation for the next work. This design may divide into nine parts: Load computation and reactive power computation and compensation; Transformer substation position and form choice; Transformer substation main transformer Taiwan number and capacity and host wiring plan choice; Short-circuit current computation; A transformer substation equipment choice and verification; Transformer substation high pressure, low pressure line choice; Short-circuit current computation; A transformer substation equipment choice and verification; Transformer substation high pressure, low pressure line choice; Transformer substation secondary circuit plan choice and relay protection installation; Anti-radar and grounding determination; Attainment and experience; Attaches the reference. Moreover has design paper 4 (to give by attached figure form), respectively is: The attached figure one "Factory district Supplies Electric wire Cable Planning drawing"; Attached figure two "Transformer substation Floor-plan"; Attached figure three "Transformer substation High pressure Electricity Main Wiring diagram"; Attached figure four "Transformer substation Low

pressure Electricity Main Wiring diagram". Because the designer knowledge grasping depth and the breadth are limited, this design Shang You the imperfect place, asked respectfully teacher, schoolmate to criticize points out mistakes!
