Abstract
(EN)
Disclosed are a surge protection device and system. The device comprises: a first switch type surge protector (PG), a second switch type surge protector (SG) and an impedance device (SI); the second switch type surge protector (SG) being connected in series with the first switch type surge protector (PG) to form a discharge channel of lightning surge current, the impedance device (SI) being connected in parallel with the first switch type surge protector (PG) to limit the amplitude of the follow current of the first switch type surge protector (PG) and to form a discharging channel of the follow current together with the second switch type surge protector (SG). The surge protection device and system can effectively avoid arc extinction failure and can improve the stability of voltage protection.

L’invention concerne un dispositif et un système de protection contre les surcharges. Le dispositif comprend : un premier parasurtenseur (PG) de type commutateur, un deuxième parasurtenseur (SG) de type commutateur, et un dispositif d’impédance (SI) ; le deuxième parasurtenseur (SG) de type commutateur étant connecté en série au premier parasurtenseur (PG) de type commutateur pour former un canal de décharge de courant de surcharge de foudre, le dispositif d’impédance (SI) étant connecté en parallèle au premier parasurtenseur (PG) de type commutateur pour limiter l’amplitude du courant de suite du premier parasurtenseur (PG) de type commutateur et pour former un canal de décharge du courant de suite conjointement avec le deuxième parasurtenseur (SG) de type commutateur. Le dispositif et le système de protection contre les surcharges peuvent éviter efficacement l’échec d’extinction d’arc électrique et peuvent améliorer la stabilité de la protection de tension.
