Infrared temperature spectrum analysis of air conductor considering vibration factor

Abstract

Through the analysis of the thermal state model of the wire, it is considered that the temperature rise is the characteristic parameter to measure the working state of the wire, which is related to the actual heat dissipation coefficient and heat dissipation surface area, and is determined by practical factors such as laying mode, operating current and thermal load, and external working condition. A method to determine its thermal state by obtaining infrared temperature spectrum is proposed, and the relatively stable temperature rise is taken as the evaluation index. The vibration condition promotes the establishment of heat exchange and its equilibrium. Different laying methods have different sensitivity to vibration and thermal stress.
