Abstract

The invention relates to a device and a method for driving a power train system (1) of a variable speed work device (3). The power train system comprises a driving machine (2), and a laminated transmission device (10). The laminated transmission device (10) comprises an input branch (11), an output branch (12) and an adjusting branch (13). Five different running modes are provided.

Description

technical field [0001] The invention relates to a device and a method for driving a drive train of a variable-speed variable-speed working machine with an increasing power characteristic curve (incremental or parabolic), for example a variable-speed working machine equipped with a superposition transmission. Fans, pumps and compressors with gear ratio transmissions, the present invention has an input branch connected to a motor or turbine, such as a steam turbine and a gas turbine, etc., a locking mechanism on the input branch, a control device and a frequency converter The control branch, the output branch is connected to the working equipment. Furthermore, the invention relates to a device, in particular a drive train with or for a device of this type. Background technique [0002] In the prior art, variable speed drives used to drive variable speed working equipment with a power of several megawatts and a speed range greater than 3000 rpm, such as variable speed turbines...
