Title:
SYSTEM AND METHOD FOR PREVENTING CORROSION OF ROTATION SHAFT
Document Type and Number:
WIPO Patent Application WO/2019/050073
Kind Code:
A1
Abstract:
The present invention relates to a system for preventing the corrosion of a rotation shaft. The system for preventing the corrosion of a rotation shaft of a rotary machine according to the present invention comprises: a shaft potential measurement unit for measuring a shaft potential difference which is the difference between the ground potential of an installation surface on which a rotary machine is installed and the shaft potential of a rotation shaft; an electric current output unit for outputting a reverse current to the rotation shaft in correspondence to the value of the shaft potential difference measured by the shaft potential measurement unit; and an active shaft potential balancing unit for continuously monitoring the shaft potential difference measured by the shaft potential measurement unit, and feedback-controlling the electric current output unit, thereby generating the reverse current.
