Abstract :
This paper introduces the principle of the fiber bragg gratings (FBG) sensor and basis of temperature analysis. According to the key technology for the fiber grating sensor which is used to detect the temperature to low-voltage circuit breaker, the technical architecture of an on-line temperature monitoring system in intelligence electric apparatus is put forward. And then, using the finite element analysis software Ansoft Maxwell, a model for the arc-extinguishing chamber of low-voltage circuit breaker was established. The temperature field was analyzed and the figures of temperature field distribution in the arc-extinguishing chamber were obtained.
