Abstract
The utility model discloses a T-shaped film for a metallized capacitor, and belongs to the technical field of capacitors. The T-shaped film comprises a thin film body, and is characterized in that metal strips are plated on the surface of the thin film body and form a plurality of independent T-shaped structures; the thin film body is a polypropylene thin film; and the metal strips are made of zinc-aluminum alloys. The T-shaped film is more rational in structural design. The metal strips plated on the thin film body are connected through micro fuses. An open-circuit failure can be realized more easily after the action of the micro fuses, so that an explosion proof effect is enhanced. The micro fuses are very flexible in responding and reliable in self-healing.
Description
Technical field:
The utility model relates to the capacitor technology field, relates in particular to a kind of T-shaped film of metallized capacitor.
Background technology:
Energy-saving and frequency-variable full-solid-state minisize intermediate frequency, high frequency, superaudio induction heating equipment.Heating, the heat treatment gas that high power switching power supply and Special Automatic control system etc. are widely used in aviation, military project manufacturing, non-ferrous metal quenches, the wide spectrums such as annealing is modified, soldering, forge hot, standard component production, machine-building have obtained generally using, and are the energy saving environmental protection products that present country widelys popularize.Adopt special power component and unique inversion transformation technique, the output frequency of oscillation reaches as high as 400kHZ, is particularly suitable for the Fast Heating of micro metal article etc.: output hunting power 20～160kVA; Output frequency of oscillation 30～150kHz; Output oscillating current 200～2000A.With these HF induction heating apparatus with it supporting crucial series resonance capacitor obtained good development space and opportunity, with regard to its design, technique, quality level larger difference is arranged.
During the electric weak point breakdown of common metal film, large value capacitor particularly, at this moment breakdown current is very large and can not control, in the self-healing process of being everlasting with the puncture of burning of the neighbouring multilayer dielectricity of self-healing point, cause the capacitor short-circuit inefficacy.
Present general excess pressure explosion-protection equipment, strict to shell and technological requirement, often because of the technique defectiveness, anti-explosion mechanism does not have explosion-proof and sets off an explosion; The capacitor of serviceability temperature fuse anti-explosion mechanism generally all will be placed on Thermal Cutoffs the centre of capacitor, in the middle of plug, the time that the capacitor generation punctures is very of short duration, if break down in the capacitor body outside, the very difficult inside that reaches fast fuse of the energy of moment makes the Thermal Cutoffs action.
The utility model content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and the T-shaped film of the metallized capacitor that a kind of self-healing is reliable, explosion-proof effect is good is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of T-shaped film of metallized capacitor comprises thin-film body, it is characterized in that: described thin-film body is coated with bonding jumper on the surface, and bonding jumper is plated to a plurality of separate T-shaped structures.
Described thin-film body is polypropylene film.
Described bonding jumper is allumen.
Open failure is finished explosion-proof task after leaning on microfuze to fuse between the bonding jumper of T-shaped structure, and its responsiveness is very fast, and is explosion-proof reliable.
The utility model structural design is more reasonable, connects by microfuze between the bonding jumper that plates on the thin-film body, and easier open failure after the microfuze action strengthens explosion-proof effect, and the microfuze reaction is very flexible, and self-healing is reliable.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of T-shaped film of metallized capacitor comprises thin-film body 2, and thin-film body is coated with bonding jumper 1 on 2 surfaces, and bonding jumper 1 is plated to a plurality of separate T-shaped structures, and thin-film body 2 is polypropylene film, and bonding jumper 1 is allumen.
Open failure is finished explosion-proof task after leaning on microfuze to fuse between the bonding jumper 1 of T-shaped structure, and its responsiveness is very fast, and is explosion-proof reliable.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
