The utility model discloses heat dispersion is good, and the safety part is high, and is small.
Description
Technical field
The utility model relates to a kind of electronic devices and components capacitor, particularly relates to a kind of parallel connection or and the metallized film pulse capacitor of series combination.
Background technology
Pulse capacitor uses very extensive, such capacitor is the vitals of laser power supply, be characterized in adapting to continuous impulse state operation, be widely used in high-pressure test device such as laser, impulse current generator, impulse voltage generator and produce in the devices such as the superpower impact of high-temperature plasma magnetic field, electromagnetic forming.Capacitor commonly used has with paper film complex media, is electrode with the aluminium foil, or the metallized film fuse through epoxy sealing in the iron case, exist heat dispersion poor, shortcoming such as fail safe is not high, and volume is big.
The utility model content
The purpose of this utility model solves existing capacitor poor radiation, the not high and bulky problem of fail safe exactly.
The technical solution adopted in the utility model is: a kind of pulse capacitor, comprise metal shell, exit, insulating base, capacitor core group, cover plate, location epoxy plate and impregnating agent composition, cover plate is provided with oil filler point, and assembling several capacitor core group in parallel or also series combination in the enclosure form by having one-sided limit and the one-sided metal level thickened area winding film of staying.
As further improvement of the utility model, be higher than the mode that 2000V adopts the back in parallel earlier series connection of single fuse when above in rated voltage, be lower than 2000V in rated voltage and adopt single fuse mode directly in parallel when following.
As further improvement of the utility model, in the above capacitor of rated voltage 2000VDC, stay the limit amount for 5-10mm, in the following capacitor of rated voltage 2000VDC, stay the limit amount to be 2.5-5mm.
As further improvement of the utility model, one-sided metal level thickened area side resistance between (2-4) Ω/mouth, in the non-thickened area side of metal level resistance between 5.5-9.5 Ω/mouth.
In sum, the beneficial effects of the utility model are: owing to adopt difference in parallel or also cascaded structure, metalized film to stay the difference thickening amount of limit amount, metal level, can strengthen gilding layer adhesive force.The self-healing performance of the dipping reinforcement metal film of core group and the heat dispersion of pulse capacitor, fail safe is higher, and the life-span is longer, and the overall volume of capacitor is also littler.
