Embodiment Construction

[0031] Such as figure 1 Shown is a schematic diagram of the composition and structure of the converter automatic test system 100 provided by the present invention, which includes:

[0032] The main control machine 110 is used to issue control instructions, control the operation of the unit modules in the test system and the control modules in the tested converter, and use the converter to perform automatic detection and obtain detection parameters;

[0033] The program-controlled switch 120, which is coupled to the main control machine 110, is used to select the route in the test system according to the control command issued by the main control machine 110, start the unit module operation on the selected route or obtain the tested converter through the selected route detection parameters;

[0034] A first program-controlled power supply 130, which is coupled to the main control computer 110, is used to set power parameters according to the control instructions issued by the ...

Abstract

The invention discloses a converter automatic test system and method. The system comprises a master control machine, a programmable switch, a first programmable power source, a power contactor and a load contactor. The system can be used to provide power for a converter automatically, select the communication path and perform automatic low-voltage tests to obtain detection parameters under the control of the master control machine. For example, in low-voltage conditions, four-quardant rectifier module low-voltage pulse tests, inverter module low-voltage pulse tests, four-quardant rectifier module current sensor tests, inverter module current sensor tests, chopping module current sensor tests and inverter module direct-current side voltage sensor tests are performed on the converter automatically, through waveform parameters acquired by a programmable oscilloscope and values of current sensors and voltage sensors acquired by a control module, the test result of the converter can be judged accurately and test data can be stored, so that comprehensive and effective failure detection can be performed.

Description

technical field [0001] The invention relates to the technical field of power electronic converter testing, in particular to an automatic testing system and method for a converter. Background technique [0002] With the increasingly wide application of converters in the field of rail transit, as a main component in the design of rail vehicles, people put forward higher and higher requirements for the quality of converters. In order to ensure the factory quality of the converter, it is necessary to conduct several hours of power assessment tests in the factory of the converter to expose its quality problems and hidden dangers in advance. [0003] Due to the problems of high test cost, high test voltage and long test time, the existing power assessment test system often becomes the bottleneck process of product production, so the throughput rate has become an important index to measure the test system. In order to improve the throughput rate of the power assessment test system...
