Abstract

The invention discloses a levitation chopper box for a maglev train, in which a radiator (3) is fixedly installed on the left side of the box body (1), the base of a power device (4) is installed on the radiator (3), and the power device ( 4) The power terminal is fixed on the left side of the upright stacked power busbar (5); while other devices in the box (1) are distributed in the space on the right side of the stacked power busbar (5), the internal control box (6) Mounted on the far right at the front of the base plate (1a). The proximity effect between components in the chopper box is small; it has few connections, takes up little space, low installation and maintenance costs, good heat dissipation effect of power devices, and small mutual interference between components, which can effectively improve the levitation of maglev trains. control system reliability.

Description

technical field [0001] The invention relates to a chopper box for a maglev train. Background technique [0002] At present, there are three types of maglev trains that have been successfully developed in the world: TR series (high speed) in Germany, MLX series (high speed) in Japan, and HSST series (low speed) in Japan. They are very different in principle, structure and performance. . The essential difference between the maglev train and the wheel-rail train is that it has a suspension control system and can run off the track. The sensor measures the suspension gap, the acceleration of the electromagnet movement and the current signal flowing through the electromagnet and inputs it to the suspension controller. The suspension processor in the suspension controller calculates the appropriate control command according to the input sensor signal, and the suspension chopper is The executive mechanism of the controller, which changes the current of the suspension electromagnet...
