Abstract

A system for automatically testing a frequency converter is provided, including an information acquisition device, a display controller, an industrial controller, a center device and a data acquisition component. The information acquisition device acquires product information of the frequency converter, the display controller recognizes the attribute of the frequency converter according to the product information acquired by the information acquisition device, the center device is electrically connected with the industrial controller and is used for pressing the testing position of the frequency converter under the control of the industrial controller after the frequency controller is placed at a testing station, the industrial controller is used for testing the frequency inverter, and thedata acquisition component collects the test data of the frequency inverter and sends the collected test data to the display controller so as to enable the display controller to analyze the test dataand display the test results. The system can automatically detect the working ability of the frequency inverter, improve the efficiency of automated test execution, save manpower and material resources, increase the accuracy of test results, and reduce the project risk and enterprise costs.

Description

technical field [0001] The invention relates to the technical field of electronic equipment detection, in particular to an automatic testing system for frequency converters. Background technique [0002] Inverter (Variable-frequency Drive, VFD) is to control the AC motor by changing the frequency of the motor's working power supply to realize the soft start of the AC asynchronous motor, frequency conversion speed regulation, improvement of operation accuracy, change of power factor, overcurrent / overvoltage / overload Power control equipment for protection and other functions. Frequency converters are often used in many important industries such as the petroleum industry, chemical industry, and manufacturing industry. Therefore, the frequency converter needs to be tested for stability or fault detection to ensure that the frequency converter is in good condition. [0003] At present, the testing of the frequency converter is mainly through manual input of detection instruction...
