Abstract

The invention relates to a nuclear power station ring crane AC frequency converter performance detection device and method. The device comprises a man-machine interaction unit, a test unit and an AC frequency converter, wherein the man-machine interaction unit is used for receiving a test instruction input by an operator, sending the test instruction to the test unit and displaying test information returned by the test unit in real time; the test unit is connected with the man-machine interaction unit and the AC frequency converter, and is used for outputting a test control signal to the AC frequency converter according to the test instruction, analyzing and processing a test signal returned by the AC frequency converter, and outputting test information; and the AC frequency converter is used for executing performance test operation according to the test control signal and returning the test signal to the test unit. The performance of a ring crane AC frequency converter can be tested, faults of the alternating-current frequency converter can be predicted in advance, the situation that maintenance and hoisting of a nuclear island are affected by the faults of the alternating-current frequency converter is avoided, and normal use of the ring crane is guaranteed.

Description

technical field [0001] The invention relates to the technical field of ring cranes in nuclear power plants, and more specifically relates to a performance detection device and method for AC frequency converters of ring cranes in nuclear power plants. Background technique [0002] As a large-scale lifting equipment of the nuclear island, the ring crane has multiple protection functions and high importance, and the performance of the frequency converter directly affects the usability of the ring crane. If the performance of the frequency converter is not good or the performance of the frequency converter is abnormal or faulty, the ring crane will not be able to work normally, which will affect the maintenance and hoisting of the nuclear island equipment. Therefore, it is necessary to test the performance of the frequency converter to predict the failure in advance. However, there is no related device or system for testing the performance of the frequency converter in the exist...
