Embodiment Construction
[0048] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0049] like Figure 1-Figure 8 As shown, the test device for the traction inverter controller of the subway includes three parts: the power generation system 10 , the control generation system 20 and the load generation system 30 , and the tested object is the traction converter unit that composes the traction inverter controller 40 41 and auxiliary converter unit 42;
[0050] The power generation system 10 is composed of a protection control cabinet 11 , a voltage regulator cabinet 12 , a rectifier power cabinet 13 and an isolation switch cabinet 14 . During the functional test and fault detection of the traction inverter controller, the power generation system 0 can generate a corresponding power supply scheme according to the power test requirements of the traction converter unit 41 and the auxiliary converter unit 42, so that the external power sup...

Provided is a device and method for testing a subway inverter controller. The device includes a control generation system comprising a PLC control cabinet, a PLC control module, an industrial personalcomputer module, a network interface module and a serial port communication interface module are arranged in the PLC control cabinet, the industrial personal computer module is arranged in a cuboid-shaped box body, a limiting member includes a cylindrical limiting through hole and a cylindrical cavity which are sequentially arranged in the direction from the front wall surface to the inside of the box body, the center line of the limiting through hole and the center line of the cavity coincide, the defects that the PLC control cabinet in the prior art doesn't have the lightening and the anti-burning functions, and the pushing operation cannot be normally realized because the push rod can be inclined and twisted under the sliding effect can be effectively prevented by combing with the method.
Description
technical field [0001] The invention relates to the technical field of subway testing, in particular to a testing device and method for a traction inverter controller of a subway. Background technique [0002] Traction inverters (such as ONIX1500 traction inverters) are widely used in the traction control of urban subway vehicle systems. In the long-term use process, its operation failure occurs continuously; [0003] At the same time, according to the requirements of regular maintenance, the urban rail transit vehicle system will enter the overhaul cycle. Among them, the traction inverter system of the vehicle system is faced with the characteristics of complex function test, difficult fault diagnosis, and high cost of equipment replacement. [0004] ONIX1500 AC traction system is a VVVF AC drive system (VVVF means variable voltage, variable frequency, that is, frequency conversion speed regulation system) specially used for electric locomotives and light rail subway trai...
