MEDIUM VOLTAGE SWITCHGEAR WITH INTERLOCKING DEVICE CORRESPONDING WITH THE SWITCHING DRIVE

摘要

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.

主权项

1. A medium voltage switchgear, comprising:
an interlocking device associated with an actuator drive, which operates a switching element via a mechanical coupling element, wherein the switching drive is movable in two end positions wherein the interlocking device is movable between a locked and an unlocked position, wherein a direction of motion of the actuator drive matches a direction of motion of the interlocking device, wherein the mechanical coupling element includes a force flux element which is rotatable during operation of the drive from OFF to ON such that a region where the interlocking shifts from unlocked to locked can freely be chosen by a shape of said force flux element.
