Abstract:
(EN) 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.
(FR) La présente invention concerne un système permettant de prévenir la corrosion d'un arbre de rotation. Le système permettant de prévenir la corrosion d'un arbre de rotation d'une machine rotative selon la présente invention comprend : une unité de mesure de potentiel d'arbre pour mesurer une différence de potentiel d'arbre qui est la différence entre le potentiel de masse d'une surface d'installation sur laquelle est installée une machine rotative et le potentiel d'arbre d'un arbre de rotation; une unité de sortie de courant électrique pour délivrer un courant inverse à l'arbre de rotation correspondant à la valeur de la différence de potentiel d'arbre mesurée par l'unité de mesure de potentiel d'arbre; et une unité d'équilibrage de potentiel d'arbre actif pour surveiller en continu la différence de potentiel d'arbre mesurée par l'unité de mesure de potentiel d'arbre et pour commander par rétroaction l'unité de sortie de courant électrique, générant ainsi le courant inverse.
(KO) 본 발명은 회전축 부식방지 시스템에 관한 것이다. 본 발명에 따른 회전 기계 장치의 회전축 부식방지 시스템은, 회전 기계 장치가 설치되는 설치면의 접지 전위와 회전축의 축전위의 차이인 축전위차를 측정하는 축전위 측정부; 축전위 측정부로부터 측정된 축전위차의 값에 대응하여 회전축으로 역방향 전류를 출력하는 전류 출력부; 및 축전위 측정부에서 측정된 축전위차를 연속적으로 모니터링 하면서 전류 출력부를 피드백 제어하여 역방향 전류를 발생시키는 능동 축전위 밸런싱부;를 포함한다.
