چکیده :
As high Voltage circuit breakers (CBs) are one of the most critical components in power grids, their proper operation is of vital importance. So real time monitoring of them is important to detect faults before undesirable interruption. CB coil is one of the main parts and also the source of many faults of it. Therefore, coil current signal can be used to diagnose a variety of circuit breaker faults in different parts of it, such as damper, power supply and coil winding, latch and auxiliary contacts. These faults shift the current curve compared to no-fault state, so in this way contribute to diagnosis of CB faults and detection of their source. Considering the importance of this matter, detecting the factors that affect the proper function curve of CBs can improve fault detection algorithms performance and decrease possibility of their failure. The environmental factors and operating conditions of CBs, and most importantly the ambient temperature is among the factors that affect their function. Thus, in the present paper a 72.5 kV SF6 circuit breaker coil is simulated in COMSOL software in order to investigate the effect of ambient temperature changes the coil function (as the factor that directly affects the temperature of electromagnetic coils).
