Abstract:

The current detection of the power loop and the signal loop is an important test item for the Solar Array Driving Mechanism (SADA). Existing detection methods perform contact detection on the SADA current loop. If the detection equipment fails or the personnel operate improperly, it will cause damage to the SADA. In order to avoid damage, a non-contact multi-channel current tester is designed based on the Hall Effect, which can effectively measure the current in the SADA power loop and signal loop without touching the target under test, and the detection accuracy is better than 0.2 %. The comparison test with the original detection method shows that the relative errors of the two methods for the SADA signal loop and power loop are both within 0.1%. It can be seen that the measurement accuracy of this instrument is sufficient to effectively meet the test requirements of the SADA signal loop and power loop, and its advantage is to reduce the risk of product damage during the detection process.
