The effects of the wear of individual parts also lose due to the reduction of the Drive unit on a few components in importance. The replacement of defective or worn components can be faster and more targeted.

Abstract

L'invention concerne une unité de commande pour un changeur de prises en charge, servant à actionner des contacts de commutation. L'unité de commande est constituée d'un boîtier, d'une bobine électrique et d'un induit. L'induit raccordé à un contact de commutation est entouré de la bobine qui est reliée au boîtier. En outre, l'induit est disposé de manière mobile le long d'un axe de symétrie. Le contact de commutation est actionné par application d'une tension électrique sur la bobine.
