摘 要自从第二次工业革命以来，电力能源就作为主要能源为全世界的经济发展做出了突出贡献。火力发电厂依然是主要的获取能源方式之一，其中电气一次设计对于实际发电效率具有深远的影响，所以在设计中选择合适的接线模式对于火力发电具有重要意义。在火力发电厂中，电气系统最主要的就是电气主接线。在满足安全性，可靠性和经济性的前提下，本文介绍了火力发电厂的设计思路，设计过程，包括主接线选择，变压器选择，断路器选择等，以当前火力发电厂电气一次设计工作开展的情况为基础，深入探究火力发电厂中电气一次设计的技术要点，旨在提高电气一次设计的科学性与合理性，为提高发电效率提供保障。关键词：火力发电厂；电气一次设计；技术要点；主接线；短路电流ABSTRACTSince the Second Industrial Revolution, power energy has made outstanding contributions to the world's economic development as the main energy source. Thermal power plant is still one of the main ways to obtain energy. The primary electrical design has a far-reaching impact on the actual power generation efficiency. Therefore, it is important to select the appropriate wiring mode in the design for thermal power generation.In thermal power plants, the main electrical wiring is the most important part of the electrical system. According to the requirements of safety, reliability, advanced technology and economic rationality in accordance with the relevant national standards, this paper introduces the design idea and design process of thermal power plants, including the selection of main wiring, transformer and circuit breaker. Based on the current situation of primary electrical design of thermal power plants, this paper deeply explores the primary electrical design technology in thermal power plants. The main points are to improve the scientificity and rationality of primary electrical design and to provide guarantee for improving power generation efficiency.Key words: Thermal Powe...
