Abstract

The invention provides a general converter electrical test device, which comprises two test areas for placing a converter to be subjected to electrical test, and at least comprises a test power supply V1 and a test power supply V2 with direct current side parameters being capable of being adjusted in real time, a test power supply V3 capable of working in a single-phase mode or a three-phase mode, and a plurality of test transformers T1, T2 and T3. The test power supply is connected to the test area through the selection switch. According to different types of test transformers arranged in different test areas, the general converter electrical test device can work in different working modes through the selection switch, and outputs different power supply types through different cooperation among test power supplies. Through real-time adjustment of the electrical parameters of each test power supply, the electrical parameters required by the test are output to the converter test object arranged in the test area. The purpose of providing electrical parameters required by the test for the unidirectional converter and the bidirectional converter is achieved, and the problems of single test function and poor universality of the test system are solved.

Description

technical field [0001] The invention relates to the technical field of electricity, in particular to an electrical test device for a universal converter. Background technique [0002] At present, the test system for converters can only meet the test requirements of unidirectional converters, while for bidirectional converters, the test system cannot meet the test requirements of bidirectional converters. [0003] To sum up, the test function of the test system is single and the versatility is poor, which cannot meet the test requirements of the bidirectional converter. Therefore, it is necessary to provide a test system to meet the test requirements of unidirectional converters and bidirectional converters. SUMMARY OF THE INVENTION [0004] In view of this, the embodiment of the present invention provides a general-purpose converter electrical test device, which is used to solve the problems of single test function and poor versatility of the test system. [0005] To ach...
