Investigating the Effect of Applying Force on DCCB Air Electric Arc
cooling in the Presence of Two Different Types of Splitter Plates
Abstract
In this paper, a novel approach of electric arc cooling with the
presence of two different types of splitter plates, in an arc chamber
direct current circuit breaker (DCCB) that has equal dimensions, has
been carefully investigated. In order to determine the thermal behavior
of the arc chamber, which plays a key role in extinguishing the electric
arc, different current densities are applied to the circuit breakers. As
more as, a 2D model of the arc chambers was suggested that could
progress the overall performance of this circuit breaker. The eligible
multi-physics contained electromagnetic physics, heat transfer physics,
and Navier-Stokes physics (MHD) are evaluated in the model to precisely
analyze the collisions and the thermal flux distribution in detail. The
model was designed and solved using COMSOL Multiphasic. By considering
these mentioned effects, it is shown via the multi-physics
finite-element analysis (MPFEA), that the performance of the device will
be progressed.
