Abstract:
A tank for a dead tank circuit breaker includes a body having an interior volume defined by an interior surface. A particle trap structure includes a pair of recessed surfaces in a bottom portion of the interior surface. Each recessed surface is disposed in spaced relation with respect to the interior surface so as to define a channel. A raised surface is spaced from the recessed surfaces and separates the recessed surfaces. The channels are constructed and arranged to trap foreign particles in the interior volume, with the raised surface being constructed and arranged to raise an electric field in the interior volume to be above the channels so as to eliminate electrical activity that would affect the particles in the channels.
