1、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
2、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
3、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 w
