Abstract

Abstract:

Abstract:When the high-power cascaded AC/DC/AC frequency converter system of mine hoist is faulty,we need find out the problem existing quickly and safety.This article mainly confirms the testing contents and designs detecting system for mine hoist transmission characteristics.The system includes: transformer power unit with high isolation, signal calibration unti, isolated amplifier unit, distance measure unit. Also we make a analysis of the testing results, and finally get a meaningful conclusion.

Key words: Keywords:mine hoist, transmission characteristics, detecting system, analysis
