Abstract

The utility model discloses a channel precision testing device for an analog quantity conditioning board card of a reactor protection system. The channel precision testing device comprises a process calibrator, a signal conditioning case and a wiring group, wherein the signal conditioning case is electrically connected with the process calibrator through the wiring group, an analog quantity conditioning board card slot is formed in the signal conditioning case and is suitable for accommodating an analog quantity conditioning board card, and the wiring group comprises an input wiring and an output wiring. As the test device is provided with the input wiring and the output wiring, the test can be carried out only by dismounting the analog quantity conditioning board card and inserting the analog quantity conditioning board card into the analog quantity conditioning board card slot in the signal conditioning case, and after the test, the input wiring and the output wiring of the analog quantity conditioning board card do not need to be connected back to the case again, so that the test efficiency is greatly improved. Therefore, the time for connecting and disconnecting the wiring can be reduced, the test period can be saved, and the wiring recovery error caused by repeated connecting and disconnecting can be avoided.
