Nuclear power plant first generation electronic actuator electronic card sensitive component testing system and method

Abstract

The present invention relates to a nuclear power plant first generation electronic actuator electronic card sensitive component testing system and method. The testing system comprises a front control device, an AC signal device, an acquisition control device, an acquisition adaption device, and a DC signal device. The front control device receives different testing cases and analyzes each testing case into different control commands. The AC signal device sends an AC testing signal to the acquisition control device. The DC signal device sends a DC testing signal to the acquisition control device. The acquisition control device sends the AC testing signal and the DC testing signal to the acquisition adaption device. The acquisition adaption device adjusts the AC testing signal and the DC testing signal and outputs the signals to an electronic actuator card for testing, and a tested feedback signal is processed and uploaded to the front control device. According to the technical scheme of the invention, the problems that an electronic actuator fault exposed in a matching testing process can not be precisely positioned by using existing technical means and the testing efficiency is low are solved.

Description

technical field [0001] The invention relates to the on-line monitoring technology of nuclear power plant power equipment, and more specifically relates to a test system and method for sensitive components of the first-generation electric head electronic card of the nuclear power plant. Background technique [0002] The electric head is an important part of the stator cooling water system of the nuclear power plant generator. 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 head is commonly used in Ling'ao nuclear power plant, and the IQ first-generation electric head is mainly composed of 7 boards, namely the main control board, power board, relay board, local input board, counter board, and position feedback board. , remote control input board, in which the main control board is the core control circuit of the motor head, the power board provides power signals for t...

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
