1. A modular holding and exchanging system for a medium or high voltage converter, comprising:
a rack for receiving at least two power modules arranged on top of one another in receiving spaces, wherein the rack has at least two pairs of vertical standing elements and at least two carrier elements connecting the vertical standing elements in a longitudinal direction of the rack in a horizontal support plane,
a separately built lifting tool that can be coupled with the rack, which lifting tool comprises a longitudinally extended profile body and one or more rolling bodies, which one or more rolling bodies are arranged at the longitudinally extended profile body, and which one or more rolling bodies can be adjusted in relation to the longitudinally extended profile body between a rest position and a support and service position for temporarily raising and moving a power module relative to the carrier elements of the rack, wherein
the power modules have support surfaces projecting in a transverse direction with respect to a housing width for being supported on the carrier elements, and
the carrier elements have an upper side provided for at least parts of the support surface of the respective power module to rest on, and are configured as a profile element such that every carrier element has at least one passage for at least one rolling body to pass through in the support and service position of the lifting tool,
and wherein the lifting tool is configured so as to be insertable into the profile element of the carrier element in the position of the lifting tool, and includes a lever device operable to adjust at least one of the rolling bodies from the rest position into the support and service position.
