Beschreibung
Zusammenfassung:	The invention relates to a method and a modular holding and exchanging system (1) for medium or high voltage converters, preferably a modular multilevel converter, comprising a rack (2) for receiving at least two power modules (3) arranged on top of one another in receiving spaces (4), wherein the rack (2) has at least two pairs of vertical standing elements (5) and at least two carrier elements (6) connecting the vertical standing elements (5) in a longitudinal direction (10) of the rack (2) in a horizontal support plane (9), a lifting tool (7) that can be coupled with the rack (2), which lifting tool (7) comprises at least one, preferably at least two, rolling bodies (19) that can be adjusted between a rest position (13) and a support and/or service position (14) for temporarily raising and/or moving a power module (4), wherein the power modules (4) have support surfaces (16) projecting in a transverse direction (11) with respect to a housing width (15) for being supported on the carrier elements (6), and the carrier elements (6) have an upper side (17) provided for at least parts of the support surface (16) of the respective power module (4) to rest on, and are configured as a profile element such that every carrier element (6) has at least one, preferably at least two passages (18), each, that are spaced apart from one another in the longitudinal direction (10), for at least one rolling body (19) to pass through in the service position (14) of the lifting tool (7), and wherein the lifting tool (7) comprises a longitudinally extended profile body (21), preferably a hollow body, configured so as to be insertable into the profile element of the carrier element (6) in the rest position (13), in which profile body (21) a lever device (20) is formed for adjusting the at least one rolling body (19), preferably of the at least two rolling bodies (19), which are spaced apart from one another in the longitudinal direction (10), from the rest position (13) into the service position (14).
