Description

technical field [0001] The invention belongs to the technical field of frequency converter testing, and in particular relates to a safe and high-precision testing device based on a low-voltage high-power mining frequency converter. Background technique [0002] As a power control device for voltage regulation and frequency regulation, frequency converter has been widely used in various industrial automation fields. Special frequency converters need to be inspected before leaving the factory to ensure their quality is qualified, so a series of tests are required for the functions of the frequency converter. [0003] The inventors have found that there are at least the following problems in the prior art: the existing functional testing of frequency converters generally passes manual quality inspection, and the operation of the testing platform is complicated. The function of the frequency converter is complex, and there are many test items. Manual inspection not only makes t...
