Abstract
The utility model discloses a kind of Novel dry DC filter capacitors, comprise integrated oxidization shell, capacitor core is provided with in described integrated oxidization shell, described capacitor core comprises multiple flattening formula element arranged in parallel and two of being welded on multiple flattening formula element outer wall connect bronze medal, described two one end connecting bronze medal are all connected with electrode guide rod by electrode bronze medal, and shell is stretched out on the top of described electrode guide rod.Its advantage is: the capacity that can improve capacitor, and good heat dissipation effect and the situation can avoiding causing capacitor body to come off because of the difference of mass expansion shrinkage ratio occur.
Description
Technical field
The utility model relates to a kind of capacitor, is specifically a kind of Novel dry DC filter capacitors.
Background technology
DC filter capacitors, is mainly used in the support link after rectification, and it runs in circuit, require that capacitor has lower inductance, require to have very large capacitance, operating ambient temperature change greatly, running current is large, and when breaking down, dipping Ji requires fire-retardant.
At present, market uses more dry type DC filtering capacitor, adopt column type element as the fuse of capacitor often, under certain installing space, when requiring large as far as possible to the actual capacity of capacitor, column type element can not be accomplished mostly (under identical material context).As supporting the capacitor of link, running current is comparatively large, adopts thick and narrow brace, can not scattering even heat, may cause local pyrexia and make capacitor generation thermal breakdown.Electric capacity is faster changed to some operating ambient temperatures, or its shell still adopts metal-back similar plastics shell, due to the cause of expanding with heat and contract with cold, capacitor body and shell is probably caused to cause coming off of capacitor body due to the difference of mass expansion shrinkage ratio, and metal shell is high to electric insulation required distance, the cabinet volume of needs is large.
Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is: provide a kind of Novel dry DC filter capacitors, can improve the capacity of capacitor, good heat dissipation effect and the situation can avoiding causing capacitor body to come off because of the difference of mass expansion shrinkage ratio occur.
Technical solution of the present utility model is: a kind of Novel dry DC filter capacitors, comprise integrated oxidization shell, capacitor core is provided with in described integrated oxidization shell, described capacitor core comprises multiple flattening formula element arranged in parallel and two of being welded on multiple flattening formula element outer wall connect bronze medal, described two one end connecting bronze medal are all connected with electrode guide rod by electrode bronze medal, and shell is stretched out on the top of described electrode guide rod.
Further, the top of described electrode guide rod is provided with the installing hole caving inward and formed.
Further, the both sides of described electrode guide rod bottom are provided with outward extending projection.
Further, described connection bronze medal is cuboid.
Further, the width of described connection bronze medal is W1, and the width of described electrode bronze medal is W2, and W1 > W2, the bottom of described electrode bronze medal is welded on the outer wall of connection bronze medal.
Apply a kind of Novel dry DC filter capacitors provided by the utility model, its beneficial effect is: capacitor core comprises multiple flattening formula element arranged in parallel and two of being welded on multiple flattening formula element outer wall connect bronze medal, instead of employing cylindrical elements, under identical volume, the capacity of capacitor can be improved to a certain extent, and connection bronze medal can improve heat dispersion, reduce capacitor self-induction, can effectively avoid the heat because producing when capacitor works evenly cannot scatter and cause the situation of the too high generation thermal breakdown of local temperature to occur, effectively improve system safety performance, integrated oxidization shell effectively can avoid a series of impacts brought because of variations in temperature brought because adopting metal shell.

Shown in figure: 1-integrated oxidization shell, 2-capacitor core, 21-flattens formula element, and 22-connects bronze medal, 3-electrode bronze medal, 4-electrode guide rod, 5-installing hole, 6-projection.
Embodiment
For more intuitively, intactly understanding the technical solution of the utility model, existing just to carry out nonrestrictive feature description in conjunction with the utility model accompanying drawing as follows:
As depicted in figs. 1 and 2, a kind of Novel dry DC filter capacitors, comprise integrated oxidization shell 1, capacitor core 2 is provided with in integrated oxidization shell 1, capacitor core 2 comprises multiple flattening formula element 21 arranged in parallel and two of being welded on multiple flattening formula element 21 outer wall connect bronze medal 22, two one end connecting bronze medal 22 are all connected with electrode guide rod 4 by electrode bronze medal 3, and shell is stretched out on the top of electrode guide rod 4.
The top of electrode guide rod 4 is provided with the installing hole 5 caving inward and formed, and facilitates electrode guide rod 4 to connect other device.
The both sides of electrode guide rod 4 bottom are provided with outward extending projection 6.Connect bronze medal 22 in cuboid.The width connecting bronze medal 22 is W1, and the width of electrode bronze medal 3 is W2, and W1 > W2, the bottom of electrode bronze medal 3 is welded on the outer wall of connection bronze medal 22.
A kind of Novel dry DC filter capacitors provided by the utility model, capacitor core 2 comprises multiple flattening formula element 21 arranged in parallel and two of being welded on multiple flattening formula element 21 outer wall connect bronze medal 22, instead of employing cylindrical elements, under identical volume, the capacity of capacitor can be improved to a certain extent, and connection bronze medal 22 can improve heat dispersion, reduce capacitor self-induction, can effectively avoid the heat because producing when capacitor works evenly cannot scatter and cause the situation of the too high generation thermal breakdown of local temperature to occur, effectively improve system safety performance, integrated oxidization shell 1 effectively can avoid a series of impacts brought because of variations in temperature brought because adopting metal shell, can also effectively reduce cabinet volume, conserve space and cost.
Certainly; these are only preferred embodiment of the present utility model and oneself; non-ly therefore namely limit to the scope of the claims of the present utility model, all utilization the utility model specifications and graphic content institute be simple and easy modification and equivalent structure change for it, all should in like manner be contained within scope of patent protection of the present utility model.
