Description
Technical field
The utility model relates to a kind of self-healing high-power metallic thin film capacitors, belong to power electronics field.
Background technique
Metallized film capacitor is to replace metal foil as electrode in the surface of polyester film vapor deposition layer of metal film, because
For layer of metallized film thickness be much smaller than metal foil thickness, therefore wind after volume also it is more small in size than type metal foil type capacitor very
It is more.The great advantage of metalized film capacitor is " self-healing " characteristic.If so-called self-healing feature is exactly thin film dielectrics due in certain point
Existing defects and there is puncture short under overvoltage effect, and the metalization layer of breakdown point can be molten in moment under arcing
Change evaporation and formed very little without metal area, make two pole pieces of capacitor again mutually insulated and remain to work on, because
This greatly improves the reliability of capacitor work.Welding forms electricity between the lead and gilding layer of existing metallized film capacitor
Resistance, causes energy loss.
Summary of the invention
（One）Technical problems to be solved
A kind of in order to solve the above problems, the utility model proposes self-healing high-power metallic thin film capacitor.
（Two）Technical solution
The self-healing high-power metallic thin film capacitor of the utility model comprising shell, lead, basement membrane, metal
Coating, outer lead and gilding layer；Lead is fixedly installed in the shell；The lead passes through basement membrane and the coat of metal,
Lead is connect with outer lead, and gilding layer is provided on lead；The basement membrane and the coat of metal are arranged using small misalignment coiling,
Basement membrane bottom is connect with gilding layer, is connect at the top of the coat of metal with gilding layer.
As preferential technical solution, the metal layer thickness is 1.2mm.
As preferential technical solution, the gilding layer bottom thickness is greater than upper end thickness.
（Three）Beneficial effect
Compared with the prior art, the utility model has the following beneficial effects：The utility model self-healing is high-power
Metallic film capacitor structure is simple, and lead is directly connected to the coat of metal, and is reinforced by gilding layer, avoids lead
The bridge resistance formed between gilding layer by welding reduces energy loss.
Detailed description of the invention

3 and the coat of metal 4, lead 2 connect with outer lead 5, gilding layer 6 is provided on lead 2；The basement membrane 3 and the coat of metal 4
It is arranged using small misalignment coiling, 3 bottom of basement membrane is connect with gilding layer 6, and 4 top of the coat of metal is connect with gilding layer 6.
Wherein, the coat of metal 4 is with a thickness of 1.2mm；6 bottom thickness of gilding layer is greater than upper end thickness.
A kind of self-healing high-power metallic thin film capacitor of the utility model has below beneficial to fruit：This is practical new
Type self-healing high-power metallic thin film capacitor structure is simple, and lead is directly connected to the coat of metal, and passes through gilding layer
It reinforces, avoids the bridge resistance formed between lead and gilding layer by welding, reduce energy loss.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality
With novel claimed technology contents, it is all described in the claims.
