Intelligent temperature detection based on finite element analysis of low-voltage circuit breaker arc-extinguishing chamber

The paper introduces equipment of intelligent temperature detection of low-voltage arc-extinguishing chamber. The equipment is based on fiber grating sensor system. Temperature data of arc-extinguishing chamber are measured by experiment. Reducing electromagnetic interference by using fiber grating sensor in the temperature measurement. Data are analyzed by the finite element software, and plotted the temperature field graph of arc-extinguishing chamber. It is very helpful improved product design technology.
