Abstract: front page image
(EN) Provided are an inrush current identification method and an identification device, equipment, and a storage medium. The method comprises: determining a time interval reference (S111); calculating an amplitude ratio between a direct current component and a fundamental component of a current of a breaker at an outlet of the transformer on the basis of the time interval reference (S112); and according to an established identification criterion, comparing the amplitude ratio of the direct current component and the fundamental component to identify whether the current of the breaker at the outlet of the transformer is an inrush current (S113).
(FR) L'invention concerne un procédé d'identification et un dispositif d'identification de courant d'appel, un équipement et un support d’informations. Le procédé consiste à : déterminer une référence d'intervalle de temps (S111) ; calculer un rapport d'amplitude entre une composante de courant continu et une composante fondamentale du courant d'un disjoncteur à une sortie d'un transformateur sur la base de la référence d'intervalle de temps (S112) ; et selon un critère d'identification établi, comparer le rapport d'amplitude entre la composante de courant continu et la composante fondamentale pour identifier si le courant du disjoncteur à la sortie du transformateur est un courant d'appel (S113).
(ZH) 一种励磁涌流识别方法及识别装置、设备、存储介质,其方法包括:确定时间间隔基准(S111);基于时间间隔基准计算变压器出口断路器电流的直流分量与基波分量幅值比(S112);按照制定的识别判据对直流分量与基波分量幅值比进行比较,识别变压器出口断路器电流是否为励磁涌流(S113)。
