Encapsulation method of thin cable with braided structure for space solar cell array

Abstract

The invention discloses a packaging method for a weaving-structured thin cable for a space solar battery array. The packaging method is characterized by comprising the steps of 1, performing installation position positioning; 2, performing surface treatment on a packaging position; 3, performing blade coating of a packaging material; 4, performing cable cleaning and forming; 5, performing primary packaging of the cable; and 6, performing secondary packaging of the cable. By adoption of the technical scheme, the packaging dimensions and positions of the weaving-structured thin cable can be effectively controlled, so as to satisfy use requirements on cable packaging thickness by special space models; the thickness is not greater than 0.3mm after a cable with the thickness of 0.2mm is packaged; the packaging material adopted by the packaging method is high in high-temperature characteristic and low-temperature characteristic; and the packaged weaving-structured thin cable can keep high structural growth rate in a track working condition, and is high in adaptivity to a complex thermal stress environment caused by space high temperature and low temperature alternation, so that the reliability and safety of the product are improved.

Description

technical field [0001] The invention relates to the technical field of power transmission for space solar cell arrays, in particular to a method for encapsulating thin cables with a braided structure for space solar cell arrays. Background technique [0002] In view of the special folding and compacting characteristics of the new generation of flexible solar cell arrays (applied to the Chinese space station project), the installation size of circular cross-section wires commonly used on rigid or semi-rigid solar cell arrays cannot meet the use requirements of flexible solar cell arrays, and The circular cross-section wire itself has no structural elongation, and it cannot work in the space orbit thermal environment with frequent high and low temperature alternating without the protection of other stress relief measures. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for encapsulating thin cables with br...
