A system and method for an electric pole part apparatus, includes an electric interruption unit; a heat sink; and a heat pipe arrangement; wherein the heat pipe arrangement comprises a plurality of heat pipes enclosed at least partially by an outer housing; wherein a first end of the heat pipe arrangement is connected to the heat sink; and wherein a second end of the heat pipe arrangement is connected to the electric interruption unit.

Electric pole part apparatus

Exemplary embodiments relate to a medium voltage switchgear with interlocking device associated with an actuator drive, which operates a switching element via a mechanical coupling element. The switching drive is movable in two end positions until which the interlocking is active between a freely selectable middle position and a specified end position. In order to keep the interlocking active over a certain range of the actuator travel, the mechanical coupling element includes a force flux element that is rotatable during operation of the drive from OFF to ON. In this way, the region where the interlocking shifts from unlocked to locked can freely be chosen by the shape of the force flux element.

Medium voltage switchgear with interlocking device corresponding with the switching drive

A pushrod assembly for a circuit breaker having a pushrod with an insulating body, an insulating housing surrounding the push rod, a first insulating shield connected to the pushrod and a second insulating shield connected to the housing. The first insulating shield and the second insulating shield are arranged inside the housing such that an electrical path through a fluid inside the housing is longer than the distance of a first end and a second end of the push rod.
