Abstract

In order to verify the feasibility that fiber-optic temperature sensor used for contact temperature measurement

the geometric structure of contact is studied

and with heat transfer theory

the software COMSOL Multiphysics is used to simulate contact temperature.In both conditions of rated current and rated short-circuit current

the distribution of contact temperature is calculated.Simulation result shows that the figure of contact is the best position for contact temperature measurement

and the maximum temperature of contact is 564℃ when short-circuit current flows.Then

the problems of fiber-optic temperature sensor installation

measurement range and strain interference are analyzed

which provs that fiber-optic temperature sensor can be used for contact temperature measurement.
