Embodiment Construction

[0026] A space power supply system and method suitable for uninterrupted maintenance of aircraft. A power supply unit, a unit switching unit, and a positive and negative busbar together form a power supply system, and the positive and negative busbars are connected with the power supply unit through the unit switching unit to form a power supply system. The number of power supply units is n It is determined according to the power supply demand of the aircraft. The positive and negative busbars supply voltage according to the power supply unit. The power supply unit performs filtering through the unit switching unit and switches the power supply path at the same time. The switched power supply unit is independent of the power supply system. For the power supply unit, the power supply system is safely replaced and maintained in the uninterrupted mode of the power supply system.

[0027] Specifically, the unit switching unit includes relays K1-Kn. Through the switching of the corr...

Abstract

The invention relates to a space power supply system and method suitable for aircraft uninterruptible power maintenance, the power supply system comprises n groups of power supply units, a unit switching unit and positive and negative buses, the positive and negative buses are connected with the power supply units through the unit switching unit to form the power supply system, and the power supply units are determined according to the power supply demand of an aircraft; the positive bus and the negative bus supply voltage according to the power supply unit, the power supply unit performs filtering through the unit switching unit and performs power supply path switching at the same time, the switched power supply unit is independent of the power supply system, and the power supply unit which does not supply power is safely replaced and maintained in a power supply system uninterruptible power mode.

Description

technical field [0001] The invention relates to a space power supply system and method suitable for uninterrupted power maintenance of aircraft, and belongs to the technical field of on-orbit maintenance of space aircraft. Background technique [0002] With the development of aerospace technology and the increasing requirements for space exploration tasks, the scale of spacecraft is getting larger and larger, and the system functions are becoming more and more complex. As my country's most complex aircraft, the Chinese space station also needs to meet the needs of long-life use. The power supply equipment has the ability to be replaced on-orbit in the maintainability design. While realizing the replaceable function of each equipment, the stable power supply demand of the power supply system still needs to be guaranteed. Therefore, while maintaining the space power supply equipment, the aircraft is guaranteed to be uninterrupted. Supply provides new technological demands. ...
