Abstract

The invention relates to a test system and method for a sensitive component of an electronic clamping piece of a second-generation electric head of a nuclear power plant. The test system comprises a front control device, an alternating-current signal device, an acquisition control device, an acquisition adaptation device and a direct-current signal device, wherein the front control device receives different test cases and analyzes the test cases into different control commands; the alternating-current signal device sends an alternating-current test signal to the acquisition control device; the direct-current signal device sends a direct-current test signal to the acquisition control device; the acquisition control device sends the alternating-current test signal and the direct-current test signal to the acquisition adaptation device; and the acquisition adaptation device conditions the alternating-current test signal and the direct-current test signal, outputs the conditioned alternating-current test signal and direct-current test signal to the clamping piece of the electric head to perform testing, processes a feedback signal of testing and uploads the feedback signal to the front control device. According to the technical scheme, the problems of incapability of accurately positioning an electric head fault occurring in a machine testing process by utilizing existing technical means, low test efficiency and the like are solved.
