Abstract

The invention provides a frequency converter voltage withstanding test method which is applied to a frequency converter voltage withstanding test system, the frequency converter voltage withstanding test system comprises an upper computer, a safety tester, a voltage withstanding test tool and a frequency converter, the upper computer, the safety tester, the voltage withstanding test tool and the frequency converter are connected in sequence, and the method comprises the steps that the upper computer receives a test instruction; based on the test instruction, the upper computer sends a control signal to the safety tester; the safety tester receives the control signal and controls the frequency converter installed on the voltage withstanding test tool according to the control signal. According to the method provided by the invention, the direct contact between the tester and the safety tester is avoided, the safety of the tester is ensured, the withstand voltage test tool is used, and the test efficiency is improved.

Description

technical field [0001] The present application belongs to the technical field of power electronics, and in particular relates to a method, system and computer-readable storage medium for withstand voltage testing of frequency converters. Background technique [0002] With the rapid development of electronic technology and communication technology, frequency converters in the field of industrial control are also developing rapidly. Inverters are widely used in industries such as crusher loads, compressor loads, and rail machine loads. In industrial applications, the requirements for overcurrent, overvoltage, and overload protection are very high. For this reason, a strict withstand voltage test is required before it leaves the factory and is put into use to prevent equipment accidents and ensure personal safety. [0003] At present, the commonly used solution for carrying out the withstand voltage test on the frequency converter is to manually connect the line between the fr...
