AI Technical Summary

Problems solved by technology

This results in a phase shift between the drive current and the drive voltage, resulting in the generation of reactive power
This inductive reactive power cannot be adequately compensated by the capacitance 8 of the supply line 6 and the capacitance 7 of the individual connected winding sections 2 , thus leading to an additional load on the drive system due to reactive power according to the prior art.
This reactive power can be actively compensated in some converters by suitable drive regulation, however this places a burden on the drive system

Embodiment Construction

[0019] figure 1 This is a device according to the prior art which has already been described above and therefore will not be described in detail here.

[0020] figure 2 An exemplary embodiment of a device 9 according to the invention is shown, which is also used for the energy supply of a long stator winding 1 composed of a plurality of winding segments 2 . The device comprises a supply line 6 which is connected via an additional line 10 and an additional line switching unit 11 to a not shown energy source such as a converter which is itself connected to the other via a rectifier circuit or a direct voltage intermediate circuit It is connected to the converter of the power supply network that transmits the alternating current. In addition, it is also possible for a further supply line 16 to be connected via a zone switch 17 to the already considered supply line 6 , which also supplies the long stator winding 2 and likewise has a correspondingly connected winding section.

Abstract

In order to provide a device for supplying energy to a long stator winding (1) having multiple winding sections (2), said device comprising an energy source, a supply line (6) connected to the energy source, section switches (3) that are connected to the supply line (6) and that each have a connection for connecting said switch to one winding section each, said device allowing the compensation ofidle power independently of the regulation of the energy source, the invention provides the means for the blind idling compensation for adjusting the impedance of the device.

Description

technical field [0001] The invention relates to a device for supplying a long stator winding with a plurality of winding segments, the long stator winding having an energy source, a supply line connected to the energy source, a supply line connected to the supply line and each having a A segment switch for the connectors to which the winding segments are connected. Background technique [0002] Such devices are known in the prior art. For example, devices for powering maglev railways are described and implemented, for example, in Shanghai, China, in which the drive is not arranged in a rail vehicle moving forward at travel speed. Instead, the drive is installed in the travel path and comprises a long stator electric machine characterized mainly by long stator windings. [0003] figure 1 A device known from the prior art for powering a maglev railway is schematically shown. It can be seen that the long stator 1 is divided into a plurality of winding segments 2 , wherein t...
