Title
(EN) AUTOMATIC MEDIUM-VOLTAGE TRANSFER SWITCHING EQUIPMENT
(FR) ÉQUIPEMENT DE COMMUTATION DE TRANSFERT DE MOYENNE TENSION AUTOMATIQUE
(ZH) 中压自动转换开关设备
Abstract
(EN)
Automatic medium-voltage transfer switching equipment, comprising a control system, wherein the control system is configured with three transfer modes: an automatic transfer mode, an on-site transfer mode and a remote control transfer mode. When the control system enters any of the transfer modes, the other two transfer modes are locked, thereby preventing the occurrence of a logic confusion phenomenon caused by multi-command operations. The automatic medium-voltage transfer switching equipment uses two vacuum circuit breakers having mechanical and electrical interlocking to carry out handover, can serve as an automatic incoming line transfer switching application having a selective line fault protection function, and can also be independently applied to a special purpose automatic dual-power supply handover switch application.
(FR)
Un équipement de commutation de transfert de moyenne tension automatique, comprenant un système de commande, le système de commande étant configuré avec trois modes de transfert : un mode de transfert automatique, un mode de transfert sur site et un mode de transfert de commande à distance. Lorsque le système de commande entre dans n'importe lequel des modes de transfert, les deux autres modes de transfert sont verrouillés, ce qui permet d'empêcher l'apparition d'un phénomène de confusion logique provoqué par des opérations à commandes multiples. L'équipement de commutation de transfert de moyenne tension automatique utilise deux disjoncteurs à vide ayant un verrouillage mécanique et électrique pour effectuer un transfert, peut servir d'application de commutation de transfert de ligne entrante automatique ayant une fonction de protection de défaut de ligne sélective, et peut également être appliquée indépendamment à une application de commutation de transfert intercellulaire automatique à alimentation double automatique.
