Problems solved by technology

[0003] At present, frequency converters are widely used, but the maintenance of frequency converters is relatively difficult. Usually, technicians go to repair them in person, and it is difficult to monitor problems with equipment and instruments. Therefore, the work efficiency is low during the maintenance process. , we propose a high-voltage inverter fault pre-diagnosis system

Abstract

The invention discloses a high-voltage frequency converter fault pre-diagnosis system. The system comprises a camera, an identification unit, a database, a monitoring unit, an analysis unit, a judgment unit, an alarm unit and intelligent equipment, wherein the camera is used for acquiring an image of a high-voltage frequency converter in real time, automatically acquiring image information and transmitting the image information to the identification unit; high-voltage frequency converter information is stored in the database and comprises high-voltage frequency converter image data and corresponding high-voltage frequency converter model data; and the identification unit acquires the high-voltage frequency converter image data from the data. According to the system, through the arrangementof the identification unit, the image acquired by the camera is identified, the type of the frequency converter is quickly judged, and the related model data is acquired; and the analysis unit performs data analysis and calculation according to the related data, so that the accuracy of data analysis and calculation is improved, the persuasion of the data is enhanced, the time consumed by analysisis shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of frequency converter fault detection, in particular to a high-voltage frequency converter fault pre-diagnosis system. Background technique [0002] The inverter is mainly composed of rectification, filtering, inverter, braking unit, drive unit, detection unit and micro-processing unit. The frequency converter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the frequency converter has many protection functions , such as overcurrent, overvoltage, overload protection, etc. With the continuous improvement of industrial automation, frequency converters have also been widely used. [0003] At present, frequency converters are widely used, but the maintenance of frequency converters is relativ...
