永宁高速公路供配电模式讨论

随着高速公路不断修建和投入运营,其配套设施的建设任务也急剧增加。交通机电系统作为高速公路运营管理是必不可少的附属系统,其涉及的知识领域广,并具有边缘应用的特点。在生产实践中,人们已经意识到,完善的高速公路交通机电系统是提高高速公路运营维护管理水平的重要手段。而机电系统的运行,依靠的是供配电系统提供的电能支持。高速公路供配电系统由变配电所、供电线路和各种用电设备等组成。供配电系统一经确定,就决定了高速公路供配电系统内部用电负荷的供电可靠性和供电质量。在充分考虑每个用电设备的工作特点和对供电质量指标的具体要求下,设计一个安全、可靠、灵活、经济的供配电系统,对保证高速公路安全运营、节能降耗、降低投资、提高经济效益等方面具有重要的意义。本文通过三明永宁高速公路供配电方案的分析,对中压供电与集中式低压配电相结合的高速公路供配电方式进行探讨。

Yongning Highway power supply and distribution pattern discussion

With the highway continue to build and put into operation,its supporting facilities construction mission also increased dramatically.Traffic electromechanical systems as highway operation and management is essential to the subsidiary system,involved in a wide field of knowledge,and the edge of the characteristics of applications.In the production practice,people have realized that the Highway Traffic electromechanical systems to improve highway operation and maintenance of an important means of management level.The operation of mechanical and electrical systems,rely on the power supply and distribution system.Power supply and distribution system is composed of substation,power supply circuit and electrical equipment.AS power supply and distribution system model is confirmed,it is decided the highway supply and distribution system of internal load reliability and quality.In full consideration of each electric equipment work and the characteristics of the power supply quality index and specific requirements,design a safe,reliable,flexible,economic supply and distribution system,to ensure highway safety operations,saving energy,reducing investment,improve economic efficiency has an important meaning.This article through to the Sanming Yongning Highway power supply schemes are analyzed,thus the medium voltage power supply and a centralized low voltage power distribution combination of highway power supply mode is discussed.
