A closure system for door openings defined in a wall (P) and comprising:-a quick-opening door (1) adjustedly installed within the door opening (H) and featuring a flexible roll-up sheet (11), an upper casing (12), and vertical uprights (3) equipped with guides (31) for the displacement of the flexible sheet (11); a fire door (2) installed at one side of the wall and comprising at least one fireproof layer (21, 23), for the opening and closure of the door opening (H), a perimeter frame constituted by the vertical uprights (3) and a rearward fireproof cover (4) of the upper casing (12) of the quick-opening door (1).

The invention relates to the technical field of circuit protection devices, in particular to a double-layer arc-extinguishing flat plate type fuse which comprises an insulating shell, a melt and a composite arc-extinguishing core, the melt is provided with a center fusing area and a terminal area which are integrally formed, and the composite arc-extinguishing core is arranged in the insulating shell and surrounds the center fusing area. A first arc extinguishing cavity for accommodating a gas production material is formed in the first arc extinguishing chamber to form a first arc extinguishing layer; and a second arc extinguishing cavity filled with an arc extinguishing medium is formed between the insulating shell and the composite arc extinguishing core body to form a second arc extinguishing layer. According to the invention, during breaking, high-pressure airflow can be quickly generated to suppress electric arcs in a segmented manner, and continuous cooling and insulation are realized by an external medium, so that the arcing time is greatly shortened, the internal pressure is effectively controlled, the shell is prevented from bursting, and the breaking capacity, safety and reliability of high-voltage and large-current faults are remarkably improved.
