Energy closed-loop ultrahydrophobic electric curtain dust removal system applied to space solar cell array
CN 105610397 A
Abstract
The invention provides an energy closed-loop ultrahydrophobic electric curtain dust removal system for a space. The energy closed-loop ultrahydrophobic electric curtain dust removal system comprises a high-voltage solar cell module, a DC/AC converter, a relay switch boosting transformer, a comb-type transparent electric curtain and an ultrahydrophobic layer. According to the working principle, 300V high voltage provided by a high-voltage power generation module provides an over 1,000V high-voltage AC power supply to the comb-type electric curtain through DC/AC conversion and boosting; and an AC field is formed on the surface of the comb-type ultrahydrophobic electric curtain which is periodically spaced. The ultrahydrophobic layer greatly reduces the surface energy; and the adsorptivity of dust on the surface of a solar cell array is reduced, so that the dust is easily lifted under the action of the electric field and moves along the direction vertical to an electrode; the dust removal target is achieved; and the removal effect on large-grain dust or accumulated dust can also be achieved under the action of gravity, shake and the like. The dust removal system provided by the invention is high in dust removal efficiency, does not affect the optical property, can achieve energy closed loop and can be isolated from a spacecraft power system.
