Abstract
Μία διάταξη προστασίας έναντι υπερτάσεων (100) με λειτουργία προστασίας έναντι βραχυκυκλωμάτων. Η διάταξη προστασίας έναντι υπερτάσεων περιλαμβάνει ένα δομοστοιχείο προστασίας έναντι υπερτάσεων (102) και ένα δομοστοιχείο προστασίας έναντι ρευμάτων βραχυκύκλωσης (101). Το δομοστοιχείο προστασίας έναντι υπερτάσεων εκφορτίζει και καταστέλλει ένα ρεύμα και μία τάση υπέρτασης, και το δομοστοιχείο προστασίας έναντι υπερτάσεων είναι ένα δομοστοιχείο εμβυσματούμενου τύπου. Το δομοστοιχείο προστασίας έναντι ρευμάτων βραχυκύκλωσης είναι ενσωματωμένο σε ένα βάθρο, και το δομοστοιχείο προστασίας έναντι ρευμάτων βραχυκύκλωσης παρέχει προστασία έναντι βραχυκυκλωμάτων και εμβυσματούμενη συναρμολόγηση για το δομοστοιχείο προστασίας έναντι υπερτάσεων. Η διάταξη προστασίας έναντι υπερτάσεων εξαλείφει τα προβλήματα όπως κρουστικό ρεύμα που προκαλούνται από τη χρήση μίας εξωτερικής διάταξης προστασίας από υπερένταση ως εφεδρικής προστασίας, ενώ η διάταξη προστασίας έναντι υπερτάσεων έχει ισχυρή ικανότητα περιορισμού ρεύματος, καλή ικανότητα διακοπής βραχυκυκλωμάτων, και μικρή ελάχιστη τιμή στιγμιαίου ρεύματος απεμπλοκής. Η διάταξη προστασίας έναντι υπερτάσεων μπορεί να αντέξει έναν τρόπο αστοχίας που λαμβάνει χώρα σε παροδική υπέρταση ("temporary overvoltage" ή "TOV"), και μπορεί επίσης να παίξει τον ρόλο προστασίας σε περίπτωση χαμηλού ρεύματος.A surge protection device (100) with short circuit protection function. The surge protection device includes a surge protection module (102) and a short circuit protection module (101). The surge protection module discharges and suppresses a surge current and voltage, and the surge protection module is a plug-in type module. The short-circuit protection module is integrated into a pedestal, and the short-circuit protection module provides short-circuit protection and a plug-in assembly for the surge protection module. The surge protector eliminates problems such as surge current caused by using an external surge protector as backup protection, while the surge protector has strong current limiting capability, good short-circuit breaking capability, and small minimum instantaneous tripping current value . The overvoltage protection device can withstand a failure mode that takes place in a transient overvoltage ("temporary overvoltage" or "TOV"), and can also play the role of protection in the event of undercurrent.
