Abstract:
Disclosed in the present invention are a pressure relief device and electrical equipment. The pressure relief device comprises a first housing and a second housing which are mutually covered and arranged, and fasteners used for connecting the first housing and the second housing; a mounting via hole is formed in the first housing; a connecting hole corresponding to the mounting via hole is formed in the second housing. A fastening assembly connects the mounting via hole and the connecting hole. First locking structures and second locking structures spaced apart from each other are matched and formed between the fastening assembly and the first housing; in an initial state, the first locking structures stop the first housing in a direction away from the second housing, and under impact of external force, the first locking structures are damaged, and the second locking structures stop the first housing in a direction away from the second housing. The technical solution of the present invention can reduce the possibility that the assemblies of the pressure relief device are exploded due to explosion, and guarantee the safety of peripheral equipment and personnel.
