Problems solved by technology

Usually, on the safety explosion-proof metallized film, a certain width of vapor-deposited metal is arranged along the longitudinal direction on the end opposite to the blank edge to thicken the edge. When the edge is thickened, the B-type gap in the original metallized grid structure still remains It cannot be plated with metal, and

Abstract

The invention discloses a BT composite safety explosion-proof metallized film, which comprises a conductive metal layer and an insulating film medium layer. A blank margin with a certain width is reserved at one end, and the metal layer is a BT composite grid structure, including an edge thickening area (5), a metallized grid (7), and connecting adjacent metallized grids ( 7) The metallized filaments (6) and the narrow strips of metallization (4) connecting the edge thickened areas (5) and the adjacent metallized grids (7). With such a structure, the edge thickening area is independent and complete, and the metallized film can be well attached when winding the capacitor core, and the gold spraying can be absorbed well; The strips of metal plating are connected, the original metallized filaments are not damaged, and the capacitor capacity is not easily attenuated.

Description

technical field [0001] The invention relates to a BT composite safety explosion-proof metallization film, in particular to a BT composite safety explosion-proof metallization film comprising a conductive metal layer and an insulating medium layer. Background technique [0002] Film capacitor is a capacitor with superior performance, which has the following main characteristics: non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), small dielectric loss, and small volume and large capacity. Therefore, film capacitors have a wide range of uses and can form different series of products, such as high specific energy storage capacitors, anti-electromagnetic interference capacitors, anti-radiation capacitors, safety film capacitors, long-life capacitors, high-reliability capacitors, and high-voltage full-film capacitors Wait. [0003] There are two main structural forms of film capacitors: one structural form is made of metal fo...
