摘要
本设计根据马莲台煤矿电力负荷的实际资料,以变电所的最佳运行为基础,按照有关规定和规范,完成了满足该区供电要求的35kV变电所一次部分的初步设计。本设计共分为5章,分别为概述、负荷分析及变压器选择、主接线的设计、短路电流的计算、高压电器设备的选择。本设计中,首先对实际的用电负荷进行了统计与计算,选出了所需的主变压器的型号,然后根据负荷性质及对供电可靠性要求拟定主接线设计,考虑到短路对系统的严重影响,设计中进行了短路计算。设计中还对主要高压电器设备进行了选择与计算,如断路器、隔离开关、电压互感器、电流互感器等。此外还进行了防雷保护的设计和计算,提高了整个变电所的安全性。
关键词: 主接线、负荷计算、变压器选型、短路计算、高压设备选型
Abstract
This design under Malian coalmine power load of actual information, to the best run substation, in accordance with the relevant regulations and norms, completed the power requirements will be met by 35 kV substation once part of the initial design. This design is divided into 5 chapters, namely overview, load analysis and transformer selection, main wiring design, short circuit current calculation, selection of high-voltage electrical equipment. This design, the first actual power load for statistics puting, selected the desired primary transformer model, and then under load properties and power supply reliability requirements drawn up by the main wiring design, considering the short circuit severe impact on the system, the design in the short-circuit evaluation. Also on the main in the design of high-voltage electrical equipment selection and calculation, such as circuit breakers, isolating switch, voltage transformer, current transformers, etc. In addition to the thunder of design putation, improves the security of the whole substation.
Key words: Main wiring, putation, transformer shaping, short-putation, high pressure unit shaping
