Converter power module operation status monitoring device

Abstract

The invention provides a converter power module operation state monitoring device. The converter power module operation state monitoring device comprises a collecting unit, a processing unit, a storage unit, a fault display unit and an input and output unit. The processing unit is respectively connected with the collecting unit, the storage unit, the fault display unit and the input and output unit; the collecting unit is used for collecting converter power module operation information and transmitting the converter power module operation information to the processing unit and the storage unit; the processing unit is used for analyzing the converter power module operation information and comparing the converter power module operation information with a standard value so as to judge the operation state of a converter power module. Because the operation information of the converter power module is compared with the preset standard value range by the processing unit, the fault state of the converter power module can be accurately judged, the operation information of the converter power module can be output through the input and output unit, and accordingly the operation state of the converter power module can be monitored and recorded in real time.

Description

technical field [0001] The invention relates to a converter power module monitoring technology of a converter, in particular to a converter power module operating state monitoring device. Background technique [0002] In a converter (such as a traction converter of an electric locomotive), the power module of the converter is an important core component, and the drive circuit of the power module of the converter is the most important. As the degree of automation of converters continues to increase and their functions become more powerful, the structure of converters is also becoming more and more complex. [0003] As the core component of the converter, the power module of the converter, how to monitor and record the operation information and fault status of the power module of the converter in real time is a technical problem that needs to be solved urgently. [0004] At present, the fault state of the power module of the converter can be detected through the Traction Cont...
