题 目：110KV变电站的运用与维护行业0材料中 文 摘 要随着经济的发展和现代工业建设的迅速崛起，供电系统的设计越来越全面、系统，工厂用电量迅速增长，对电能质量、技术经济状况、供电的可靠性指标也日益提高，因此对供电设计也有了更高、更完善的要求。设计是否合理，不仅直接影响基建投资、运行费用和有色金属的消耗量，也会反映在供电的可靠性和安全生产方面，它和企业的经济效益、设备人身安全密切相关。变电站是电力系统的一个重要组成部分，由电器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。作为电能传输与控制的枢纽，变电站必须改变传统的设计和控制模式，才能适应现代电力系统、现代化工业生产和社会生活的发展趋势。随着计算机技术、现代通讯和网络技术的发展，为目前变电站的监视、控制、保护和计量装置及系统分隔的状态提供了优化组合和系统集成的技术基础。随着电力技术高新化、复杂化的迅速发展，电力系统在从发电到供电的所有领域中，通过新技术的使用，都在不断的发生变化。变电所作为电力系统中一个关键的环节也同样在新技术领域得到了充分的发展。变电站内的高压配电室、变压器室、低压配电室等都装设有各种保护装置，这些保护装置是根据下级负荷地短路、最大负荷等情况来整定配置的，因此，在发生类似故障是可根据具体情况由系统自动做出判断应跳闸保护，并且，现在的跳闸保护整定时间已经很短，在故障解除后，系统内的自动重合闸装置会迅速和闸恢复供电。这对于保护下级各负荷是十分有利的。这样不仅保护了各负荷设备的安全利于延长是使用寿命，降低设备投资，而且提高了供电的可靠性，这对于提高工农业生产效率是十分有效的。工业产品的效率提高也就意味着产品成本的降低，市场竞争力增大，进而可以使企业效益提高，为国民经济的发展做出更大的贡献。生活用电等领域的供电可靠性，可以提高人民生活质量，改善生活条件等。可见，变电站的设计是工业效率提高及国民经济发展的必然条件。关键词：变电站 输电系统 配电系统 高压网络 补偿装置 ABSTRACT Along with the economic development and the modern industry developments of quick rising, the design of the power supply system become more and more completely and system. Because the quickly increase electricity of factories, it also increases seriously to the dependable index of the economic condition, power supply in quantity. Therefore they need the higher and more perfect request to the power supply. Whether Design reasonable, not only affect directly the base investment and circulate the expenses with have the metal depletion in colour metal, but also will reflect the dependable in power supply and the safe in many facts. In a word, it is close with the economic performance and the safety of the people. The substation is an importance part of the electric power system, it is consisted of the electric appliances equipments and the Transmission and the Distribution. It obtains the electric power from the electric power system, through its function of transformation and assign, transport and safety. Then transport the power to every place with safe, dependable, and economical. As an important part of powers transport and control, the transformer substation must change the mode of the traditional design and control, then can adapt to the modern electric power system, the development of modern industry and the of trend of the society life.Along with the high and quick development of electric power technique, electric power system then can change from the generate of the electricity to the supply the power.High-voltage power distribution room substation, transformer room, installation of low-voltage power distribution room so there are various protection devices, these protective devices are based on the lower ground short circuit load, maximum load, etc. to tuning configuration, therefore, in the event of a similar failure is made automatically by the system to determine the specific circumstances of the trip should be protected, and now tripping protection setting time is very short, after the failure to lift, automatic reclosing device within the system and gate quickly restore power. This is for the protection of the lower level of the load is very favorable. This will not only protect the safety of each load to prolong the service life of equipment, reduce equipment investment, and improve the reliability of power supply, which is to improve the efficiency of agricultural production is very effective. Improve the efficiency of industrial products means lower production costs, increase market competitiveness, in turn, can enable enterprises to improve efficiency, the development of the national economy and make greater contribution. The reliability of electricity supply and other areas of life, can improve the quality of peoples lives and improve living conditions. Visible, the substation is designed to improve industrial efficiency and economic development of the inevitable conditions.Keywords:substation transmission system distribution high voltage networkcorrection equipment. 目 录 1 绪论151.1研究背景及必要性151.2国内外现状151.3研究内容与研究方法162 110KV变电站概述172.1 110KV变电站简介172.2 待建变电站负荷计算172.3变压器选择182.4主接线设计原则202.5所用电的设计242.6继电保护的配置252.7防雷保护283 110KV变电站在运行过程中的常见故障分析与处理333.1GIS的常见故障及其防范措施333.2监控设备故障及其防范措施343.2.1监控设备的故障及其原因343.2.2防范措施343.3 变压器故障及其防范措施353.3.1变压器运行中的故障及其原因353.3.2处理方法及防范措施353.4全绝缘、半绝缘、绕组材料等问题的解决354 110KV变电站的日常维护保养364.1日常维护保养36 4.2日常运行维护385 结论416 致谢42行业0材料 1 绪论1.1研究背景及必要性变电站是电力系统的重要组成部分，它直接影响整个电力系统的安全与经济运行，是联系发电厂和用户的中间环节，起着变换和分配电能的作用。电力工业是国民经济的重要部门之一，它是负责把自然界提供的能源转换为供人们直接使用的电能的产业。它即为现代工业、现代农业、现代科学技术和现代国防提供不可少的动力，又和广大人民群众的日常生活有着密切的关系。电力是工业的先行。电力工业的发展必须优先于其他的工业部门，整个国民经济才能不断前进。我国具有极其丰富的能源。这些优越的自然条件为我国电力工业的发展提供了良好的物质基础。但是，旧中国的电力工业落后，无法将其利用。不过，随着改革开放的深入发展，我国电力工业的发展很快。到2000年，我国电力工业已跃升世界第2位，电力工业的发展为我国的国民经济的高速发展做出了巨大的贡献。不仅如此，目前我国的电力工业已开始进入“大电网”、“大机组”、“超高压交、直流输电”等新技术发展的新阶段，一些世界水平的先进的高新技术，已在
