Abstract: In allusion to the air compressor and nitrogen compressor trip fault in oxygen making machine unit operation caused by a company compressor stating, after repeatedly oxygen-compressor starting tests, it was determined as a DC system power supply fault finally, and the fault cause and treatment process were analyzed. The corresponding counter measures were raised. The actual operation verifies that the treatment effect is fine, which provides experience and references for similar faults.
Key words: oxygen-compressor start; air-compressor; nitrogen-compressor; trip; DC power supply fault
