Pressing device for a cast-resin dry-type electric transformer

摘要

A pressing device for a cast-resin dry-type electric transformer is described. The pressing device is configured to block a medium-voltage winding with respect to a yoke clamp. The pressing device comprises: a rack and gear wheel mechanism; a pair of bases, wherein the rack and gear wheel mechanism is configured to move the two bases away from each other towards the yoke clamp and towards the winding; and a blocking device for blocking rotation of the gear wheel.
