Description
Technical field
The present invention relates to fixed capacitor field, in particular to a kind of capacitor with long service life.
Background technique
Capacitor is that dielectric material by two electrodes and therebetween is constituted.Dielectric material is a kind of dielectric, when being set to
When in the electric field between two pieces of parallel plate electrodes with the equivalent charges of different polarity, polarization electricity is generated in dielectric surface due to polarization
Lotus then increase accordingly the charge being strapped on pole plate, maintains the potential difference between pole plate constant.Here it is capacitors to have capacitor
The reason of feature.
The capacitor mentioned in this programme is electrolytic capacitor, and electrolytic capacitor commonly used in the prior art is zinc electrolysis electricity
Container, zinc is hard and frangible under room temperature, but zinc can become flexible at 100 to 150 DEG C；Capacitor is used under high temperature environment
When device, the solute component of solute volatilization in electrolyte, vaporization is discharged to capacitor external diffusion, even if being penetrated using solute gas
Property the sealing of lower butyl rubber solute gas can not be prevented to spread.
In order to solve this problem, Chinese patent CN102714100B discloses a kind of capacitor, including capacitor element,
The made of metal shell of the electrolyte being at least impregnated in capacitor element, the bottomed tube for storing capacitor element and electrolyte
The seal body of the opening portion of body and seal casinghousing.Moreover, further having the portion being set to the appearance face contact of seal body
Divide coating layer that is upper and being formed and being scattered in adsorbent in resin, above-mentioned adsorbent is contained in electrolyte for adsorbing
Solvent.Alternatively, seal body is made by being scattered in above-mentioned adsorbent in rubber constituent.
But use above scheme can only the delay capacitor Inner electrolysis matter dry time, come into the solute of seal body
Gas will continue to external diffusion, so that sealing intracorporal solute gas concentration and capacitor internal solute gas concentration generation concentration
Difference, so that solute gas is still to external diffusion, while in normal use capacitor, the solute in electrolyte also can be frequent
It is lost during to capacitor charging/discharging.
Summary of the invention
The invention is intended to provide a kind of capacitor with long service life, led with solving solute formation gas diffusion in electrolyte
The technical issues of causing electrolyte to lose dielectric characteristic.
Capacitor with long service life in this programme, including box body, secondary box, anode and cathode, the anode and cathode
It is connected to the lower section of box body, anode and cathode are spring, and above box body, being equipped between box body and secondary box will be connected to the pair box
The electrolysis liquid pipe that box body is connected to secondary box, electrolysis liquid pipe are telescoping tube, are equipped in the electrolysis liquid pipe from secondary box and lead to box body
Liquid valve, the electrolysis liquid pipe are externally provided with the switch button of control liquid valve, can touch open after being equipped with rotation by the switch button
The switch block of button is closed, box body top is equipped with connecting rod, and connecting rod connects box body and secondary box, and connecting rod bends box body pair to switch button direction
Box, the pair box are equipped with fixed feet；
The box body is provided with No.1 electrolyte, and secondary box is provided with No. two electrolyte, solute in No. two electrolyte
Concentration is greater than No.1 electrolyte.
In use for some time, the intracorporal solute of box is depleted capacitor in this programme, the box body after solute loss
It lightens, under the action of it is the anode and cathode of spring that the shape of box body bottom, which is arranged in, box body is popped up, and is arranged in box body
The connecting rod pair box of top is bent to switch button direction, and the switch button of control liquid valve is opened by connecting rod, opens after liquid valve No. two
Electrolyte and No.1 electrolyte mixing, and due to the concentration of solute in No. two electrolyte be higher than No.1 electrolyte in solute it is dense
Degree, thus in No.1 electrolyte solute concentration improve, thus make No.1 electrolyte can continue to using.
It, can be in anode and cathode when the weight of box body lightens because of solute loss after anode and cathode are set as spring
It is popped up under effect, so that box body is drawn close to secondary box；No. two electrolyte enabled in secondary box above box body are arranged in secondary box
Flow to box body；Electrolysis liquid pipe is that electrolysis liquid pipe is unaffected when telescoping tube pops up box body, avoids box body by electrolyte
Pipe plug lives to lead to not bounce；The liquid valve being arranged in electrolysis liquid pipe makes the solute in No.1 electrolyte enough in use, two
The continuation of number electrolyte avoids being lost in secondary box；The switch block being arranged in by switch button can trigger switch button in rotation；If
The connecting rod set on the box body two sides opposite with secondary box is bent when box body is bounced to switch button direction, to touch opening liquid
The switch button of valve；Secondary box, which is equipped with fixed feet, makes secondary box be maintained at motionless above box body.
Using the capacitor of this programme, the secondary box above box body is arranged in from trend box body in dependence in use for some time
The solute of interior supplement loss, reaching solute formation gas diffusion in solution electrolyte causes electrolyte to lose dielectric characteristic
The purpose of technical problem, when the solutes content in the intracorporal No.1 electrolyte of box is enough, box body declines again, and connecting rod leaves out
Button is closed, liquid valve is closed, and No. two electrolyte stoppings are mixed with No.1 electrolyte, is lost again to the solute in No.1 electrolyte dangerous
To the greatest extent, No. two electrolyte can provide solute again, cause electrolyte to lose to solve solute in electrolyte and form gas diffusion
The technical issues of going dielectric characteristic.
Further, the positive electrode is tantalum, and negative electrode material is copper.
Tantalum and copper all have good ductility, by they be made spring can it is flexible, compared to using only 100 to
150 DEG C just have malleable aluminium do anode it is more stable.
Further, the liquid valve is made of heat-barrier material.
The capacitor of this programme can generate heat in box body when in use, and the heat can accelerate the damage of solute in electrolyte
Consumption, after liquid valve is made of heat-barrier material, the temperature remains within the normal range for No. two electrolyte in secondary box, reduces the damage of solute in No. two electrolyte
Consumption.
Further, the secondary box is made of heat-barrier material, and box body is made from a material that be thermally conductive.
The capacitor of this programme is powered in box body when in use generates heat, box body made of Heat Conduction Material by heat outwardly
Discharge, and No. two electrolyte in secondary box are intended only as the supplement of No.1 electrolyte, No. two electrolyte are not when using capacitor
Electrolytic process is participated in, the heat that No. two electrolyte are subject to all is from the external world, so it is only necessary that box body is made with heat-barrier material,
It will be isolated from extraneous heat.
Further, the electrolysis liquid pipe is hard telescoping tube.
Hard telescoping tube is flexible to vertical direction when box body is bounced, and torsion can be controlled when box body pops up compared to using
Bent soft telescopic pipe can touch switch button after capable of guaranteeing connecting rod bending, to open liquid valve as electrolysis liquid pipe.
Further, the fixed feet has two.
Compared to the scheme that a fixed feet is only arranged, two fixed feets can prevent secondary box skew, while not will increase again
The area that the capacitor installation of this programme needs.
Further, the anode and cathode include spring section and pin portions, and the spring section is spiral shape, institute
Stating pin portions is linear, and spring section connects box body and pin portions.
After being arranged in this way, when anode and cathode are welded to the position of needs, anode and cathode with pin portions
It is stronger compared to the welding of not pin portions.
