Abstract

Aiming at the problems of low monitoring frequency, low efficiency and poor accuracy of composite insulator temperature monitoring system for transmission line, a temperature monitoring method of high voltage AC composite insulator is proposed. The Maxwell equation is established by using the variational principle. Combined with the potential function, the electric field strength of the composite insulator of the transmission line is obtained, and then the electric field distribution of the composite insulator of the transmission line is calculated. The influence of the magnetic field force, temperature and arc resistance on the current in the arc time model is analyzed, and the arc speed control equation of the composite insulator of the transmission line is obtained. The arc time model of transmission line composite insulator is constructed. Combined with the temperature monitoring principle of transmission line composite insulator, the temperature of transmission line composite insulator is monitored. The results show that the proposed method can not only improve the temperature monitoring frequency and efficiency, but also improve the monitoring accuracy by reducing the temperature monitoring error.
