Abstract

The invention provides an aerotrain control apparatus. The control apparatus is simple in structure, more reasonable in layout, and capable of improving control accuracy and the connection reliability of various components of a control means. The control apparatus comprises a casing, a power device and a heatsink, wherein the power device is internally installed in the casing, the power device controls the suspension force of a suspension electromagnet, the heatsink lies in the casing and forms an inner surface of the housing, and the power device is arranged on the heatsink. By the control apparatus, a fan and an air duct in the casing are saved, heat dissipation is realized by the heatsink, so that the structure is simplified to a greater extent and the weight is reduced. The heatsink lies on the entire inner surface of the casing, thus the heating radiating area is expanded and the heat dissipation is accelerated. The installation and the removal of the heatsink are relatively simple, the heatsink is more convenient and faster to control, and then the efficiency of the control apparatus can be improved to some extent and the maintenance cost is reduced.

Description

technical field

[0001] The invention relates to the technical field of rail transit, in particular to a control device for a suspension train. Background technique

[0002] In the prior art, the operation of the maglev train is controlled by a levitation controller. The levitation processor in the levitation controller calculates appropriate control commands based on the levitation gap measured by the levitation sensor, the vertical acceleration of the electromagnet, and the current data passing through the electromagnet, and transmits them to the levitation chopper. The command adjusts the electromagnetic force between the electromagnet and the rail, thereby adjusting the suspension gap and realizing the stable suspension of the train.

[0003] Due to the large inductance of the levitation electromagnet, when the current changes rapidly, the electromagnet will generate a high counter electromotive force, and the levitation chopper must bear high voltage and current. Under...
