Description
Technical field
This utility model is related to power capacitor field, in specifically a kind of high-voltage power capacitor integral type lamellar
Fuse.
Background technology
It is made up of through different going here and there and connect the little element of several storage electric charges inside high-voltage power capacitor,
On the basis of meeting certain energy, each the little element within most of high-voltage power capacitor can be in series with an Internal fuse,
When little element punctures, other intact little elements Internal fuse that element little with fault is connected that can release energy fuses,
Thus by little for fault element excision out it is ensured that the normal operation of other intact little elements.As can be seen that high-voltage power capacitor
Internal fuse used by inside is extremely important, needs action when fusing, must not action when should not fusing.And in ensureing
The safety of fuse performance and the reliability of action, in conjunction with some parameter requests such as the dissimilar, capacity of high-voltage power capacitor,
Choose the Internal fuse size being suitable for and structure, be extremely important technical requirements.
At present in existing technical scheme, the structure of high-voltage power capacitor Internal fuse and placement location mainly have following several
Kind：
1st, the Internal fuse of round shape shape, two is made a distinction using the part of hank knotting shape and middle fusing, and viscose glue is in little unit
The big face of part.
The Internal fuse of this structure make relatively simple, can be with using machinery production mode.But subject matter
Have：
1）Because the environment that high-voltage power capacitor runs is under high voltage, being uniformly distributed of electric field is very important,
High-voltage power capacitor press-fits into a fuse by several little elements by certain height and forms, and round shape fuse is positioned over unit
Between part and element, big face, can be expressed to element pole plate, thus leading to the distortion of this part pole plate electric field being expressed to, electric field is abnormal
Become and seriously will induce puncturing of element；
2）How to ensure the concordance of Internal fuse live part, directly influence whether Internal fuse application when action consistent
Property and reliability.This structure two ends need hank knotting, and hank knotting end is easier damaged with the changeover portion of live part, has influence on
The concordance of Internal fuse live part.
2 and lamellar plate welding round shape Internal fuse, Internal fuse two be respectively welded at lamellar draw plate on,
It is directly adhered to the big face of little element.
This structure major defect has：
1）Make relative complex, need manually to carry out the welding of two ends fuse, relatively time-consuming, and due to many
, can there is artificial rosin joint, weldering uncontrollable risk such as loosely in the welding step of two points；
2）The concordance of the live part length of Internal fuse has the larger deviation of ratio, and two is welded to long point in plate
Or short point all can have influence on concordance and the reliability of Internal fuse action.
3）Because Internal fuse is toroidal, it is positioned between two little elements big face, when much individual little element is fitted in one
When rising, still can be expressed to element, cause a certain degree of damage to little element.
Content of the invention
The technical problems to be solved in the utility model is to overcome existing defect, provides one kind both to can guarantee that Internal fuse action
Concordance and reliability, and do not interfere with the reliability of the internal little element of high-voltage power capacitor itself, in Internal fuse
Make upper and relatively easy, reliable high-voltage power capacitor integral type lamellar Internal fuse.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme：
A kind of high-voltage power capacitor integral type lamellar Internal fuse, it is by the tin plating copper sheet structure through mould punching
Become, described tin plating copper sheet includes coupling part and live part, described live part is located at the centre of tin plating copper sheet, described effective
Partial is respectively arranged at two ends with coupling part, and described coupling part and live part are integral type structure.
Further, the thickness of described tin plating copper sheet is 0.05-0.2mm.
Further, the width of described live part is 0.3-2mm.
Further, the length of described live part is 60-250mm.
Further, described live part also includes being made up of two tin plating copper sheets in parallel.
Further, the width of described live part is 0.15-1mm.
Further, the length of described live part is 120-150mm.
A kind of this utility model high-voltage power capacitor integral type lamellar Internal fuse is using very thin copper sheet hard-cover mould
It is stamped to form, can be very good to control the length and width of Internal fuse it is ensured that the concordance of fuse live part, precision is higher than gold
Belong to silk, the root of Internal fuse also will not cause to damage because of stranded or soldering.In addition, being positioned between two little elements big face, by
In fuse is very thin and thickness uniformly, substantially will not be damaged to little element, improve the operational reliability of little element.
Brief description
Accompanying drawing is used for providing further understanding to of the present utility model, and constitutes a part for description, with this practicality
New embodiment is used for explaining this utility model together, does not constitute to restriction of the present utility model.In the accompanying drawings：
