Title:
SURGE PROTECTOR WITH DUAL TRIPPING MECHANISMS
Document Type and Number:
WIPO Patent Application WO/2022/218066
Kind Code:
A1
Abstract:
A surge protector with dual tripping mechanisms, comprising two tripping structures respectively arranged on a frame (1). The two tripping structures are respectively a first tripping structure and a second tripping structure. The first tripping structure comprises a sliding block (7) and a first tension spring (2). One end of the first tension spring (2) is connected to the frame (1), and the other end of the first tension spring (2) is connected to the sliding block (7). The second tripping structure comprises a second tension spring (8). One end of the second tension spring (8) is connected to the frame (1), and the other end of the second tension spring (8) is connected to a reed (3). When the surge protector is triggered, the first tension spring (2) drives a slider (7) to move to an electrode (10) and is located between the electrode (10) and the reed (3), and the second tension spring (8) drives the reed (3) to move in the direction away from the electrode (10). The two tripping structures are independent of each other. When the first tripping structure fails, the second tripping structure can still work normally, such that the tripping of the surge protector is normal, and the occurrence probability of the tripping abnormality is reduced.
