Abstract: front page image
(EN)The present invention relates to an apparatus for removing partial discharge noise and to a method for diagnosing partial discharge. The apparatus comprises: a noise removing device which removes, upon occurrence of a partial discharge signal, noises from a partial discharge signal using a reaction speed difference of signals and outputs a signal from which noises are removed; a laser module which outputs, upon the occurrence of a partial discharge signal, laser to a surface of power equipment and extracts sound wave and vibration data from a reflection signal of the laser; a correlation analyzing unit which compares the partial discharge signal from which noises are removed, input through a sensor connection unit, and sound wave and vibration data extracted through the laser module so as to analyze a correlation; and a partial discharge diagnosing unit that performs a partial discharge diagnosis on the signal of which at least one of a generation period, generation time and phase of sound wave and vibration data corresponds to the partial discharge signal from which noises are removed, as a result of the correlation analysis performed by the correlation analyzing unit.
(FR)La présente invention concerne un appareil d'élimination de bruit de décharge partielle et un procédé de diagnostic de décharge partielle. L'appareil comprend : un dispositif d'élimination de bruit qui élimine, lors de l'apparition d'un signal de décharge partielle, des bruits à partir d'un signal de décharge partielle à l'aide d'une différence de vitesse de réaction de signaux et délivre en sortie un signal duquel des bruits sont éliminés ; un module laser qui délivre en sortie, lors de l'apparition d'un signal de décharge partielle, un laser vers une surface d'équipement de puissance et extrait des données de vibration et d'onde sonore à partir d'un signal de réflexion du laser ; une unité d'analyse de corrélation qui compare le signal de décharge partielle duquel des bruits sont éliminés, l'entrée à travers une unité de liaison de capteur, et des données de vibration et d'onde sonore extraites par le module laser, de manière à analyser une corrélation ; et une unité de diagnostic de décharge partielle qui réalise un diagnostic de décharge partielle sur le signal dont au moins l'un d'une période de génération, d'un temps et d'une phase de génération de données de vibration et d'onde sonore correspond au signal de décharge partielle duquel des bruits sont éliminés, par suite de l'analyse de corrélation réalisée par l'unité d'analyse de corrélation.
(KO)본 발명은 부분방전 노이즈 제거 장치 및 진단방법에 관한 것으로, 부분방전 신호 발생 시, 신호의 반응속도 차이를 이용하여 부분방전 신호의 노이즈를 제거하고, 노이즈가 제거된 신호를 출력하는 노이즈 제거 장치, 부분방전 신호 발생 시, 전력기기 표면으로 레이저를 출력하고, 레이저의 반사 신호로부터 음파 및 진동 데이터를 추출하는 레이저 모듈, 센서 연결부를 통해 입력되는 노이즈가 제거된 부분방전 신호와 레이저 모듈을 통해 추출된 음파 및 진동 데이터를 비교하여 상호 연관성을 분석하는 상호 연관성 분석부, 및 상호 연관성 분석부의 상호 연관성 분석 결과, 노이즈가 제거된 부분방전 신호와 음파 및 진동 데이터의 발생 주기, 시간, 및 위상 중 적어도 하나가 일치하는 신호에 대하여 부분방전 진단하는 부분방전 진단부를 포함한다.
