Abstract: A power supply battery and a power supply system for high-speed maglev trains are disclosed. The power supply battery comprises: an electrolyte tank, a plurality of liquid flow pumps, and a plurality of aluminum-air battery reactors. The plurality of aluminum-air battery reactors are sequentially connected in series. The electrolyte tank comprises a plurality of elongate electrolyte grooves. One liquid flow pump corresponds to one aluminum-air battery reactor and one electrolyte groove.

Abstract: An integrated electromagnet comprises a magnetic yoke and magnetic poles in two rows. An axis of magnetic core in the magnetic pole is perpendicular to the magnetic yoke. The magnetic poles comprise first and second magnetic poles that are arranged alternatively in a row. The first magnetic pole in any row is adjacent to the second magnetic pole in the other row. The first magnetic poles in a row are connected to a one-way output controller and the second magnetic poles in a row are connected to a bidirectional output controller. In a guiding state, the magnetic poles in a row have a same polarity, and a polarity of the magnetic poles in one row is opposite to that in the other row; current output by the bidirectional output controller in a braking state has direction opposite to current output by the bidirectional output controller in the guiding state.

Abstract: An inserted connection member for a train connector includes an insertion needle, an insulator, a disconnection preventing pad and an extrusion block. The insulator is sequentially provided with a positioning hole and an inserted connection hole in an axial direction. The insertion needle includes a line connecting segment, a positioning segment and an inserted connection segment which are connected sequentially, the line connecting segment and the positioning segment are arranged in the positioning hole. The disconnection preventing pad and the extrusion block are both sleeved on the line connecting segment, and the disconnection preventing pad includes a pad body and a boss arranged on the pad body. Thus, the insertion needle is ensured to maintain a stable contact even when the train is running at a high speed, and a disconnection preventing effect of the insertion needle is achieved.

Abstract: An interlocking control device for a multiple-unit safety circuit is provided, which includes: a protective grounding switch control branch which includes: a pantograph rising pneumatic circuit cut-off valve, a protective grounding switch turn-off pneumatic circuit cut-off valve and a protective grounding switch turn-off solenoid valve which are connected in series. When high-voltage equipment of a multiple-unit train is under maintenance or is powered by an external power supply, a protective grounding switch is turned on, cocks of the pantograph rising pneumatic circuit cut-off valve and the protective grounding switch turn-off pneumatic circuit cut-off valve are rotated to open a cover of a key box, the protective grounding switch control branch is disconnected, the protective grounding switch turn-off solenoid valve connected in series in the protective grounding switch control branch is powered off to maintain the protective grounding switch in an on state.
