L'unité de commutateur de disjoncteur 24KV est composée de trois pôles, du mécanisme de fonctionnement et du boîtier du mécanisme de fonctionnement. La séquence des pôles est A -B - C ou 1-2-3 (séquence de gauche à droite vue du côté terminal inférieur de l'unité de commutation de reproche.
Chaque disjoncteur à vide 24kv parGOPOWEREst intégré dans un poteau isolé solide en résine époxy cyclo aliphatique résistante aux intempéries. Cela permet une petite conception ainsi qu'une résistance aux effets environnementaux.
Contactez-nousZW32 series 24KV circuit recloser are used in distribution systems. 24kv vacuum circuit breakes are used to make and break normal and fault currents. Breakers are fully equipped with sensors and a controller to provide a means of protection and control. For more pole top switches at bulk price.
In case of a line fault, breakers can break and make currents several times, thus avoiding longer network interruptions due to temporary faults. The manufacture, design, and testing of the vacuum recloser is based on current standards IEC 62271-111：2019
