The Research of Contact Feeling Temperature Indicator Based on Curie Temperature for Transmission Line
Transmission lines are important parts of power system,their operation decided directly those of the power system security and efficiency.In order to monitor the operation temperature of contact nodes in the transmission lines,an online indicator based on Curie temperature characteristics was designed.Using the temperature sensing characteristics of ferrite material,and the principle that temperature changing will change magnetic field force,the temperature indicating device was developed.It ensures that an alarm indicating cap portion jumped up as soon as the temperature reaches the set value,the alarm indicating cap portion was coated with conspicuous color,so facilitate patrol staff will found in time and then master the changing the transmission line contact temperature to avoid accidents.Tests in laboratory and operation experience had shown that the device could effectively monitor the temperature of transmission lines as to improve the transmission capacity of transmission line.
