Problems solved by technology
Most of the satellites currently in orbit use a single-switch one-way circuit for deployment indication resistance. During the satellite launch process, once a switch in the deployment indication circuit loop cannot be closed normally, the ground telemetry will not be able to correctly interpret the solar wing. Whether the in-orbit deployment is normal, if the power does not match the expected situation, the specific position of the undeployed part of the solar panel cannot be judged

The invention discloses a circuit for failure prevention of a solar wing deployment indicator switch, belonging to the technical field of satellite power supplies. Backup, deployment indicator switch backup includes deployment indicator switch A installed on the upper side of the substrate and deployment indicator switch B installed on the lower side of the substrate, and deployment indicator switch A is adjacent to the solar panel A where the deployment indicator resistor is installed; deployment indicator backup The circuit includes: three groups of wires drawn from both ends of the unfolding indicating resistance module, the three groups of wires are respectively group A, group B and group C; the electrical connector is installed on the solar panel A, and the cable clip is installed on the solar panel The side of the panel on the adjacent side of A and solar panel B. The invention realizes the separation of the unfolding indicating resistance and the unfolding indicating switch, and the obstacles and failures of the unfolding indicating switch will not affect the obstacles and failures of the unfolding indicating resistance.
Description
technical field [0001] The invention belongs to the technical field of satellite power supplies, and in particular relates to a circuit for failure prevention of a solar wing deployment indicator switch. Background technique [0002] As we all know, the solar cell array is the heart of satellite energy. Whether the solar wing can be deployed normally has become one of the decisive links for the success or failure of the satellite launch. The deployment of the indicator resistance circuit is used as a technical means for telemetry to judge whether the solar wing is deployed normally, and the rationality of the indicator circuit design is deployed. Whether the telemetry data that directly affects the deployment of the solar wing on the ground is correct. Most of the satellites currently in orbit use a single-switch one-way circuit for the deployment indication resistance circuit. During the satellite launch, once a switch in the deployment indicator circuit cannot be closed no...
