【摘要】 在社会用电量日益增加的今天,如何提高输电线路的输送容量是目前电力部门比较关注的一个问题。本论文从导线热容量与输电线路载流量的关系入手,提出了输电线路动态增容的概念,并提出了输电线路动态增容监测系统的思路。导线温度监测装置是动态增容监测系统的重要组成部分,本论文提出了导线温度监测装置的总体结构,并重点对导线温度监测装置的电源进行了研制。提出了利用CT直接从母线取能为主,蓄电池供电为辅的电源设计方案,并完成了对电源电路的设计。通过仿真和实验表明,电源的性能符合装置的要求。更多还原

【Abstract】 Today, the demanding of electricity consumption of society is increasing gradually,so how to enhance the transmission capacity of transmission lines is concerned by powerdepartment. This paper proposes the concept of dynamic increasing-capacity oftransmission lines by the relation of transmission conductor thermal capacity and currentcarrying capacity of transmission line, and proposes the thinking of monitoring systemof dynamic increasing-capacity. Because the importance of conductortemperature-monitor device, its structure is proposed. And its power supply is developedemphatically. This paper proposes the scheme that using the CT to attain the energy fromthe buses as the main power and the accumulator as the accessorial power. The results ofsimulation and experiment indicate that the power supply can meet the demand of deviceto the power.更多还原
