Abstract
The utility model provides a novel thin high -pressure high -power membrane the capacitor post, is provided with the skeleton, and the skeleton is located the intermediate position of stem stem, is equipped with heat conduction rubber on the skeleton, and heat conduction rubber is located the both sides limit of skeleton respectively, and the skeleton is symmetrical structure, is equipped with the clearance between the skeleton, the high nonconformity in heat conduction rubber both sides on the skeleton, the skeleton is a mouthful word column structure. Through be equipped with heat conduction rubber on the skeleton, can be fine derive the heat of stem stem is favorable to that stem stem self is thermal to be gived off to further improve the heat stability of electric heater, adopt the skeleton of aluminium plate making material with the skeleton, can optimize the mechanical properties of stem stem.
Description
Technical field
The utility model relates to a kind of stem stem, is specifically related to a kind of Novel thin high-power membrane capacitance stem stem.
Background technology
Film capacitor works as electrode with metallized film, by itself and poly-ethyl ester, polypropylene, the film such as polystyrene or Merlon, after the overlap of two ends, be wound on hold stem stem forms cylindric structure have core film capacitor.Core film capacitor is had to be the predominate architecture of the large merit film capacitor of current high pressure and to be widely used in the fields such as new forms of energy (solar energy, wind energy etc.), electric automobile.As the poly-ethyl ester (0.020 ~ 0.030W/ (mK)) of capacitor dielectric material, polypropylene (~ 0.622W/ (mK)), film self thermal conductivity coefficients low (being often used as heat-barrier material) such as polystyrene (0.039 ~ 0.041W/ (mK)) or Merlon (~ 0.19W/ (mK)), and the little radiating condition of capacitor own vol is poor, easily cause capacitor long-play under full-load power to occur capacitor area thermal breakdown phenomenon, there will be electric capacity time serious and burn.Improve capacitor to be fully loaded with ability to work and can be reduced on the one hand capacitor equivalent resistance by the contact resistance etc. reducing capacitor gilding layer and evaporation layer contact berrier, gilding layer and lead-in wire and reduce capacitor self-inductance by the selection of capacitor arrangement and gage system, lead material and trend etc., reduce capacitor induction reactance, also himself radiating condition can be improved by varying capacitors structure, improve capacitor thermal stability, reduce thermal breakdown of capacitor possibility.At present, Large Copacity film capacitor adopts core column structure usually, and the material of stem stem is generally the low Heat Conduction Materials such as PVC (0.14 ~ 0.17W/ (mK)), be unfavorable for the heat radiation of capacitor, this stem stem, from improvement core column structure, by improving one's methods to core column material selection, structural design etc., makes stem stem from single skeleton function, become and not only there is skeleton function, and there is the Novel button stem of lead-in wire and heat sinking function simultaneously.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, a kind of Novel thin high-power membrane capacitance stem stem that insulation effect is good.
Summary of the invention of the present utility model is: a kind of Novel thin high-power membrane capacitance stem stem, be provided with skeleton, described skeleton is positioned at the centre position of stem stem, described skeleton is provided with heat conductive rubber, described heat conductive rubber lays respectively at the dual-side of skeleton, and described skeleton is symmetrical structure, is provided with gap between described skeleton, heat conductive rubber both sides height on described skeleton is inconsistent, and described skeleton is mouth shape structure.
Be provided with heat conductive rubber outside described skeleton, be provided with dielectric layer outside described heat conductive rubber, described dielectric layer is positioned at the periphery of skeleton, described skeleton have backing plate, described backing plate is other is provided with weld tabs.
Described skeleton top is provided with lead-in wire, and described lead-in wire is divided into lead-in wire B1, lead-in wire B2 and lead-in wire A, described lead-in wire A to be positioned at the centre position of lead-in wire B1 and lead-in wire B2, is connected with dielectric layer under described lead-in wire B1 and lead-in wire B2.
Described skeleton is aluminium panels skeleton, and described skeleton is respectively equipped with backing plate up and down, and described backing plate is provided with connection boss, and heat conductive rubber blocks by described connection boss, and described heat conductive rubber is between dielectric layer and skeleton.
The utility model has the advantages that: by being provided with heat conductive rubber on skeleton, the heat of stem stem can well be derived, be conducive to distributing of stem stem self heat, thus improve the thermal stability of electric heater further, skeleton is adopted the skeleton of aluminium panels, the mechanical performance of stem stem can be optimized, the serviceability of stem stem is optimized greatly, can manufacturing cost be saved.
