Test system and method for sensitive components of the second-generation electric head electronic card of nuclear power plant

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.

Description

Technical field [0001] The invention relates to an online monitoring technology for power equipment of a nuclear power station, and more specifically, to a testing system and method for sensitive components of a second-generation electric head electronic card of a nuclear power station. Background technique [0002] The electric head is an important component in the stator cooling water system of the generator of a nuclear power station. Its function is to control and display the opening of the valve to ensure the normal operation of the cooling water system. At present, the IQ series electric heads are commonly used in Ling Ao Nuclear Power Plant. The second-generation IQ electric heads mainly include the main control board, power supply board (IQ10-35 or IQ40-91), relay board, local input board, counter board, Position feedback board, torque feedback board, CPT board. The main control board is the core control circuit of the electric head. The power board provides 24VDC working...

Problems solved by technology

[0004] At present, the detection of the electric head in nuclear power plants is limited to the functional test of the entire device, and there is no experience in performing relevant functional tests on its internal components, let alone the understanding of internal components of the components, so we must pass advanced experiments Equipment and network communication technology to explore new methods for testing electric head clamps of nuclear power plants
