Abstract

The invention discloses an HXD3 type electric locomotive converter monitoring device which comprises an MUC chip and a ground analysis system. Analog quantity signals of all connectors of input and output ports of a CI control unit of the converter are monitored in real time, analog-to-digital conversion is carried out on all the analog quantity signals, and then waveform state analysis is carried out through an MUC chip; digital quantity signals and input and output signals of an external intermediate relay of the converter are monitored in real time, and then digital quantity state processing is carried out by an MCU chip; and the MUC chip operates a ground analysis system, and the ground analysis system executes each working thread and performs processing and fault judgment according to waveform state analysis and digital quantity state processing results obtained by the MUC chip.

Description

technical field [0001] The invention belongs to the technical field of electric locomotive monitoring, in particular to an HXD3 type electric locomotive converter monitoring device. Background technique [0002] The converter is the key electrical equipment of the HXD3 electric locomotive, and its operating condition directly determines the integrity rate of the entire locomotive. Although the converter itself is a highly intelligent device with a fault diagnosis system based on fault code technology, many converter faults cannot be monitored due to the harsh working conditions of the converter and the complexity of its structure. In particular, the fault diagnosis board of the converter control unit has low detection accuracy and few diagnostic items, and it is impossible to report faults such as "CI secondary overcurrent", "PG output abnormality" and "traction motor no current" to the converter. Detection, can not meet the needs of the locomotive operating on-site convert...
