Problems solved by technology

This method can only realize the self-detection of the sensor in the converter, but cannot detect the type of contactor and module inside the converter, and must rely on the current source signal generator of the self-testing system

Embodiment 1

[0043] Such as figure 1 As shown, this embodiment is used for the self-testing method of the traction converter of the rail transit vehicle, and the steps include:

[0044] S1. Pre-load two or more self-inspection control modules and store configuration parameters in the DCU unit of the traction converter to be inspected. Each self-inspection control module is used to control different traction converter components to perform self-inspection and configure parameters. It is used to control the start-up self-test, and correspondingly determine whether the self-test of different traction converter components passes;

[0045] S2. Load the stored configuration parameters when the DCU unit of the traction converter to be inspected is powered on, and start the self-inspection according to the configuration parameters. During the execution of the self-inspection, each self-inspection control module is used to control the self-inspection of each component of the traction converter. An...

Embodiment 2

[0066] This embodiment is basically the same as Embodiment 1, except that this embodiment is specifically controlled by the embedded processing unit on the DCU to complete the entire traction converter self-inspection process, and the ground control terminal writes the configuration parameters into the embedded system through the communication interface. In the non-volatile memory of the processing unit, the configuration parameters include the start-up judgment conditions, the threshold value for judging whether the self-test is passed, and the start-up mode parameters, such as Figure 5 As shown, the steps to realize the self-test of the traction converter are:

[0067] Step 1: After the DCU is powered on, the embedded processing unit automatically loads the configuration parameters. If the start mode parameter is set to automatic, it will automatically enter the judgment of "whether the start judgment condition is met"; if the start mode parameter is set to manual, it will w...

Embodiment 3

[0074] This embodiment is used for the self-testing device of the traction converter of the rail transit vehicle, including:

[0075] More than two self-inspection control modules are preloaded in the DCU unit of the traction converter to be inspected, and are used to control different traction converter components to perform self-inspection;

[0076] The configuration parameter module is pre-stored in the DCU unit of the traction converter to be inspected, and is used to store configuration parameters. The configuration parameters are used to control the startup self-inspection and correspondingly determine whether the self-inspection of different traction converter components passes;

[0077] The self-inspection execution module is used for self-inspection and loads the stored configuration parameters when the traction converter DCU unit is powered on, and starts the self-inspection according to the configuration parameters. During the self-inspection execution process, each ...

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a self-inspection method and device for traction converters of rail transit vehicles. Background technique [0002] The traction converter is the core component of the train electric drive system, and its operating state directly affects the reliable operation of the entire train electric drive system. The internal components of the traction converter are mainly divided into: ①contactors, including charging contactors, shorting contactors, auxiliary transformer output contacts, etc.; ②sensors, including voltage sensors, current sensors, speed sensors, etc.; ③contains switching tubes Modules, including rectifier module, inverter module, auxiliary module, etc. If any of the above components fails, it will affect the normal operation of the traction converter, so it is necessary to detect the status of each component in the traction converter. [0003] At present, the...
