Magnetic coupling electric reactor

Abstract

A magnetic coupling electric reactor has different functions in different work modes. In the first work mode, the magnetic coupling electric reactor serves as an electric reactor with a small inductance value and capable of allowing large currents to pass through and can be used for a vehicle-control-type main circuit of a subway vehicle traction system. In the second work mode, the magnetic coupling electric reactor works as multiple electric reactors capable of being used simultaneously and with large inductance values and can be used for a frame-control-type main circuit of the subway vehicle traction system. The magnetic coupling electric reactor comprises a coil assembly and a copper bar assembly, wherein the coil assembly comprises at least two coaxial coil sets formed by stacking a plurality of coils with different ends in serial connection, the adjacent ends of the coil sets are different ends, and each coil set comprises an input line end and an output line end; the copper bar assembly includes lead-out copper bars and short-circuited copper bars, the lead-out copper bars are connected with the input line ends of the coil sets or the output line ends of the coil sets, and the short-circuited copper bars can connect or disconnect the lead-out copper bars connected with the input line ends and the lead-out copper bars connected with the output line ends.

Description

technical field [0001] The invention relates to a reactor, in particular to a magnetic coupling reactor. Background technique [0002] At present, there are mainly two main circuits in the traction system of subway vehicles: vehicle-controlled main circuit and frame-controlled main circuit. One line reactor needs to be installed in the vehicle-controlled main circuit, while two line reactors need to be installed in the frame-controlled main circuit, and the two reactors work simultaneously when the vehicle is in normal operation. A multi-purpose reactor that can be used in both the vehicle-controlled main circuit and the frame-controlled main circuit is needed in the traction system of subway vehicles, so as to reduce the number and type of reactors, thereby reducing the cost. But there is no reactor with a simple structure that can be used as a reactor with a small inductance value and can pass a large current-used in the main circuit of the vehicle control type, and can b...
