Title
(EN) BREAKER OPEN/CLOSURE CONTROLLER
(FR) DISPOSITIF DE COMMANDE D'OUVERTURE/FERMETURE DE DISJONCTEUR
(JA) 遮断器の開閉制御装置
Abstract
(EN)
A pole-opening command signal or pole-closing command signal is outputted to a breaker after at most one cycle waiting time when a pole-opening command signal or a pole closing command signal is detected, and the breaker is opened or closed at a desired phase of a main circuit current or a system voltage. A breaker open/closure controller (100) comprises open/closure control signal output time calculating means (10) and open/closure command signal output delaying means (20). With reference to the detection timing of the pole-opening or pole-closing command signal, the open/closure control signal output time calculating means (10) calculates an open/closure control signal output time so as to open or close the breaker at a desired phase after a time which is the sum of the open/closure control signal output time and the predicted pole-opening or pole-closing time of the breaker (620) has elapsed. The open/closure command signal output delaying means (20) outputs a delayed pole-opening or pole-closing command signal to the breaker after the latest open/closure control signal output time has elapsed when a pole-opening or pole-closing command signal is actually detected.

Cette invention concerne un signal de commande d'ouverture de pôle ou un signal de commande de fermeture de pôle qui est émis à un disjoncteur après un temps, au plus, d'attente de cycle lorsqu'un signal de commande d'ouverture de pôle ou un signal de commande de fermeture de pôle est détecté, et le disjoncteur est ouvert ou fermé à la phase voulue du courant de circuit principal ou de la tension de système. Un dispositif de commande (100) d'ouverture/fermeture de disjoncteur comprend un moyen (10) de calcul de temps d'émission du signal de commande d'ouverture/fermeture, et un moyen (20) de retard d'émission du signal de commande d'ouverture/fermeture. En référence à la temporisation de détection du signal de commande d'ouverture de pôle ou de fermeture de pôle, le moyen (10) de calcul du temps d'émission du signal de commande d'ouverture/fermeture calcule un temps d'émission du signal de commande d'ouverture/fermeture afin d'ouvrir ou de fermer le disjoncteur à la phase voulue après que la période de temps qui est la somme du temps d'émission du signal de commande d'ouverture/fermeture et du temps d'ouverture de pôle ou de fermeture de pôle prédit du disjoncteur (620) s'est écoulée. Le moyen (20) de retard d'émission du signal de commande d'ouverture/fermeture émet un signal de commande d'ouverture de pôle ou de fermeture de pôle retardé au disjoncteur après que le dernier temps d'émission du signal de commande d'ouverture/fermeture s'est écoulé lorsqu'un signal de commande d'ouverture de pôle ou de fermeture de pôle est réellement détecté.

 本発明は、開極指令信号又は閉極指令信号を検出した時に、最大でも1サイクル以下の待ち時間で開極指令信号又は閉極指令信号を遮断器に対して出力し、主回路電流又は系統電圧の所望の位相で遮断器を遮断又は投入させることを可能にした。遮断器の開閉制御装置100は、開閉制御信号出力時間算出手段10と開閉指令信号出力遅延手段20とを備え、開閉制御信号出力時間算出手段10は、開極指令信号又は閉極指令信号の検出タイミングを基準として、開閉制御信号出力時間と遮断器620の予測開極動作時間又は予測閉極動作時間の和の時間経過後に遮断器が所望の位相で遮断又は投入するように開閉制御信号出力時間を算出し、開閉指令信号出力遅延手段20は、開極指令信号又は閉極指令信号を実際に検出した場合、最新の前記開閉制御信号出力時間経過後に、遅延制御された開極指令信号又は遅延制御された閉極指令信号を遮断器に対して出力する。
