Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0049] Such as Figure 1-Figure 7 As shown, the test device for the traction controller of the subway system 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 41 that constitutes the traction inverter controller 40 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...

Abstract

The invention discloses a device and method for testing a traction controller of a subway system, and the device comprises a control generation system. The control generation system comprises a PLC control cabinet, and the interior of the PLC control cabinet is provided with a PLC control module, an industrial control computer module, a network interface module, and a serial port communication interface module. The industrial control computer module is disposed in a cuboid-shaped box body, and the cuboid-shaped box body is made of aluminium alloy. The top wall of the cuboid-shaped box body and the bottom wall of the cuboid-shaped box body are respectively welded with a cuboid-shaped top plate and a cuboid-shaped bottom plate. A manual operation control cabinet is connected to a supporting seat body fixed on the ground, and a structure where the manual operation control cabinet is connected with the supporting seat body is that the manual operation control cabinet is fixedly connected to the supporting seat body. The manual operation control cabinet is shaped like a cuboid. The supporting seat body is shaped like a cuboid. The above combination method effectively irons out the defects in the prior art that a PLC control cabinet does not have the function of avoiding electric shock caused by lightning and flame resisting, is not simple in configuration and is not convenient to install.

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 controller of a subway system. 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 trains...
