As formed by metallized capacitance film coiling, metallized capacitance film is the vacuum evaporation layer of metal layer electrodes on dielectric film,
Clearance for insulation is set on existing common metal film, prevent in metalized film self-healing procedure with neighbouring more of self-healing point
Layer medium is burnt breakdown, causes capacitor short-circuit to fail.But the setting of clearance for insulation sometimes increases electric current in part simultaneously
Collect, cause the electric current that collects excessive and uncontrollable, finally add metalized film on the contrary by breakdown probability of burning, shadow
Ring actual use.
Utility model content
To solve problems of the prior art, the utility model provides that a kind of self-healing is safe and reliable, service life
The metallized film of long resistance to rush of current.Concrete technical scheme is as follows：
A kind of metallized film of resistance to rush of current, including dielectric layer, the dielectric layer is provided with metal level and blank is stayed
Side, the metal level are provided with some longitudinal clearance for insulations and some lateral isolation gaps, longitudinal clearance for insulation and transverse direction
The metal level is divided into the thickening pole plate unit of common the pole plate unit and circular configuration of matrix arrangement by clearance for insulation, described to add
Thick pole plate unit is located at the connection intersection in longitudinal clearance for insulation and lateral isolation gap, the thickening pole plate unit and phase
It is electrically connected between adjacent common pole plate unit by fanning annular fuse layer.
As the improvement of above-mentioned technical proposal, the annular fuse layer of fan passes through longitudinal clearance for insulation or transverse direction between any two
Clearance for insulation separates.
As the improvement of above-mentioned technical proposal, annular fuse layer is fanned in the edge for thickening pole plate unit with four simultaneously
The tangent connection in short arc side.
As the improvement of above-mentioned technical proposal, the common pole plate unit is common including the first common pole plate unit and second
Pole plate unit, the first common pole plate unit are located at the centre position on dielectric layer, and the second common pole plate unit is located on dielectric layer
Close to the both sides of dielectric layer.
As the improvement of above-mentioned technical proposal, 4 arc-shaped edges are carried on the first common pole plate unit, described second is general
Lead on pole plate unit and carry 2 arc-shaped edges, the arc-shaped edges on the first common pole plate unit and the second common pole plate unit are equal
Overlapped with the long arc side for fanning annular fuse layer.
The beneficial effects of the utility model are：The utility model is by the sharp corner of common pole plate unit of the prior art
Arc-shaped edges are changed to, and the arc-shaped edges is thickeied pole plate unit by fanning the connection of annular fuse layer, make to collect in the past square sharp
The electric current of corner can be shunted quickly, be not in the situation that electric current comes together in a bit, improve the metallized film
Resistance to rush of current ability；Simultaneously because the fan annular fuse layer easily fuses, there is the function of safety fuse, when wherein a certain
When there is electric current breakdown on common pole plate unit, disruptive discharge electric current can fuse annular fuse layer is fanned, and make the common pole plate list
Member is dielectrically separated from, the sprawling for avoiding electric current from puncturing.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the metallized film of resistance to rush of current of the utility model.
Embodiment
As shown in figure 1, a kind of metallized film of resistance to rush of current provided by the utility model, including dielectric layer 7, it is described
Dielectric layer 7 is provided with metal level and blank stays side 1, and the metal level is provided with some longitudinal clearance for insulations 5 and some transverse directions are exhausted
The metal level is divided into the common pole plate list of matrix arrangement by intermarginal gap 6, longitudinal clearance for insulation 5 and lateral isolation gap 6
The thickening pole plate unit 3 of member 2 and circular configuration, the thickening pole plate unit 3 are located at longitudinal clearance for insulation 5 and lateral isolation
The connection intersection in gap 6, by fanning annular fuse layer 4 between the thickening pole plate unit 3 and adjacent common pole plate unit 2
Electrical connection.
The annular fuse layer 4 of fan is separated by longitudinal clearance for insulation 5 or lateral isolation gap 6 between any two.
The edge for the thickening pole plate unit 3 tangent connection in short arc side with four annular fuse layers 4 of fan simultaneously.
The common pole plate unit 2 includes the first common 201 and second common pole plate unit 202 of pole plate unit, and first is general
Logical 201 centre position on dielectric layer 7 of pole plate unit, the second common pole plate unit 202 are located on dielectric layer close to medium
The both sides of layer.
4 arc-shaped edges are carried on the first common pole plate unit 201,2 are carried on the second common unit of pole plate 202
Individual arc-shaped edges, length of the arc-shaped edges with fanning annular fuse layer on the first common pole plate unit and the second common pole plate unit
Arc side overlaps.
The sharp corner of common pole plate unit of the prior art is changed to arc-shaped edges by the utility model, and makes the arc-shaped edges
Pole plate unit is thickeied by fanning annular fuse layer connection, the electric current for enabling to collect in the past at square sharp corner obtains quickly
Shunting, is not in the situation that electric current comes together in a bit, improves the resistance to rush of current ability of the metallized film；Simultaneously because
The fan annular fuse layer easily fuses, and has the function of safety fuse, is hit when there is electric current on wherein a certain common pole plate unit
When wearing, disruptive discharge electric current can fuse annular fuse layer is fanned, and be dielectrically separated from the common pole plate unit, avoid what electric current punctured
