A New Approach on Condition Assessment of MV Switchgear Based on Thermal Evaluation

The increase in load demand in the power system, distribution switchgears result in more attention from the thermal point of view. In this article, a 3D model of the connection of the circuit breaker to the switchgear (plum contact) of the VD4 CB of ABB Company has been simulated through COMSOL soft...

Description
Summary:The increase in load demand in the power system, distribution switchgears result in more attention from the thermal point of view. In this article, a 3D model of the connection of the circuit breaker to the switchgear (plum contact) of the VD4 CB of ABB Company has been simulated through COMSOL software. The heat has been recorded in its different parts. Subsequently, variations in temperature have been observed under different currents and ambient temperatures. Finally, according to the simulations, the temperature slope variable has been investigated at different ambient temperatures and it has been introduced as an independent diagnosis index to the ambient temperature.
