Research on Fault Analysis and Fault Diagnostics Technology for Large-Size Equipments in Stopes

Abstract:

At present,the main equipments is electric shovels of Dagushan Iron Ore Mine, Due to a variety of factors, inevitably, there are many faults, overcurrent, overvoltage and overload are the ones with highest incidence. at the same time, the lifting system, push-press system, rotation system on the electric shovel and the overcurrent protection system of the main transformer will make appropriate actions and instantaneously shut down the electric shovel. In this article, microcomputer as its control core, It can comprehensively take use of equipment status monitoring technology, test analysis technology, signal processing technology, embedded technology, etc., carry out analytical reasoning for the equipment status information during operation process of electric shovel such as current, voltage, etc., according to the simulation experiment and operation inspection and test, the large-size equipment diagnosis & analysis device is completed for stopes has the advantages such as full-featured functions, convenient and reliable operation, considerable economic benefits.
