Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As Figure 1-3, the utility model provides a kind of protection device of self-healing type parallel condenser, including capacitor
Top cover 1, relief tube 2, insulated copper ribbon 3, element 4, aluminium pot 5 and bottom 6, the top of aluminium pot 5 are provided with capacitor top cover 1, aluminium pot 5
Bottom be provided with bottom 6, the inside of aluminium pot 5 is provided with pyrocondensation copper strips 3 and element 4, and bottom 6 is provided with hollow and thin-walled in the middle of top
Annulus 62, the top of hollow and thin-walled annulus 62 is provided with rounding 61, and one end of relief tube 2 is connected with hollow and thin-walled annulus 62, separately
One end contacts with capacitor top cover 1.
Relief tube 2 is circular ultra-thin wall construction, and this thin-wall construction is simple, and pressure release passage can be made unimpeded, and gas can be made again
Readily penetrated through with material or extruded, relief tube 2 does not have space with the junction interference fit of bottom 6, in capacitor resin by injection
When, resin may not flow into relief tube so as to block pressure release passage, it is ensured that whole pressure release passage is smooth in capacitor running
Lead to without additional drag.The junction of hollow and thin-walled annulus 62 and bottom 6 is provided with stepped circular configuration 63, and its is stepped to ensure that
Element 4 is not contacted directly with bottom when element 4 loads bottom 6, leaves certain safe distance, resin is substantially filled to element
Insulating properties and thermal diffusivity are ensure that between bottom.The bottom surface of bottom 6 is along the circumferential direction provided with three cushion blocks 64, in the bottom surface of bottom 6
The heart is provided with support annulus 65, and cushion block and support annulus can effectively support the element assembly of whole capacitor, and take up room pole
It is small, resin can be made to be substantially filled between bottom 6 and aluminium pot 5.
Concrete operating principle：The center of bottom 6 uses hollow and thin-walled structure, and thin-walled top uses rounding 61, makes relief tube
During loading quick and precisely, production efficiency is effectively raised；The thin-walled of bottom 6 uses circular shape structure with bottom surface junction, this
Structure is called " safe distance block ", the mandrel of the effective support capacitor of energy, resin is sufficient filling with the bottom of element, has
Element when preventing winding or metal spraying from there is error of effect is directly contacted with bottom, it is ensured that pass through heat in capacitor running
Resin is endlessly distributed, and effectively extends the service life of capacitor；Annular cushion block is used in the middle of bottom bottom,
Bottom margin along the circumferential direction has three cushion blocks 64, and these can guarantee that between bottom and aluminium pot full of resin, both ensure that insulation
Radiating effect well has been reached again；Relief tube is using circle without dead angle structure, and tube wall is relatively thin, is produced during capacitor instantaneous short circuit
Amount of heat, makes a large amount of gases drive thin-film material to readily penetrate through thin-walled and enters pressure release passage, or gas extrusion relief tube, makes
Overvoltage protection quick acting, greatly reduces the loss that failure is brought, additionally, in making its easy embedded bottom again, realizing and bottom
The interference fit of lid, prevent resin flow into relief tube in hinder capacitor faults when gas close pressure release passage into relief tube
Close.
The beneficial effect that the utility model is reached is：The apparatus structure is simple, and easy to assembly, production efficiency is high, passes through
The cooperation of each part, enables capacitor disconnection capacitor when breaking down more rapidly, safe, so that capacitor operation is more
Safety.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to the utility model with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent.It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc.,
Should be included within protection domain of the present utility model.
