VS1-24 Vacuum Circuit Breaker
Description du produit:
Le disjoncteur moyen d'intérieur de vide de la tension VS1 est un C.A. triphasé 50Hz, la tension évaluée 6KV,12KV, équipement du commutateur 24KV du système d'alimentation.
Le briseur adopte la conception intégrale du mécanisme de déclenchement et du corps de briseur, qui peut être employé comme unité fixe d'installation ou comme chariot individuel de VCB ainsi que le handcart. Ils ont une longue espérance de vie. Il n'y a aucun effet négatif sur le vide, même de la commutation fréquente des courants de fonctionnement et de court-circuit.
Nos produits sont largement utilisés dans:
1-Transformateurs et sous-stations de distribution
2-Contrôle et protection du générateur
3-Contrôle et protection de la banque de condensateurs, etc.
