Abstract
The invention discloses a super-capacitor reinforcement method, belongs to the technical field of avionics and particularly belongs to the technical field of airborne avionics applied to strong vibration environments. The super-capacitor reinforcement method has the advantages that an aluminum shell clamps a core tightly by being extruded, so that shaking of the core in the shell under the vibration environments is avoided, and a common super-capacitor with the aluminum shell is tolerable to long-time strong vibration; as verified by actual vibration tests, the super-capacitor reinforced by the method is undamaged, can be used for the airborne avionics and meets requirements of the aviation field completely.
Description
Technical field
The invention belongs to avionics field, be particularly applied to the airborne electronic equipment under strong vibration environment.
Background technology
Ultracapacitor adopts special warfare, achieves very large capacitance in less volume.The size of same Φ 35 × 60, conventional alminium electrolytic condenser capacity generally accomplishes 33mF, and super capacitor then can reach 400F, and capacity is the former 12000 times.Therefore, in avionics system, super capacitor is the perfect medium of Large Copacity power storage.
But, because tantalum electric capacity aircraft progressively adopting performance more excellent carrys out substitution of Al electrochemical capacitor, the super capacitor of same employing aluminum hull encapsulation, do not use in a large number aboard at the beginning of birth, but towards industrial circle application, as doing power storage in new forms of energy (wind-powered electricity generation, solar power generation etc.) system.In these areas, super capacitor (group) works in metastable environment, and its operating temperature range generally, between-40 DEG C ~ 60 DEG C, does not tolerate the demand of strong vibration substantially.
Along with updating of technique, there is part super capacitor can reach the operating temperature range of air environment-55 DEG C ~ 70 DEG C at present, possessed the primary condition in air environment application.But air environment operational environment is comparatively severe, except the operating temperature range of-55 DEG C ~ 70 DEG C will meet, also want the requirement that can tolerate the vibration of long-time of numerous values.In practical application, under airborne equipment strong vibration condition (vibration in 6 hours), super capacitor internal electrode brace is easily because there is the situation (statistics failure rate reaches more than 80%) of fracture in vibrating fatigue.
Analyze the reason that super capacitor ruptures at strong vibration condition bottom electrode brace, mainly because there is gap between electric capacity core body and shell, under vibration condition, core body in the enclosure portion's high frequency rocks, and causes brace to fracture.
Reinforcement means traditional on avionic device has: the methods such as gluing, embedding (adhesive curing is added in gap), mechanical consolidation (adopting screw, cuff), but, because super capacitor core body soaks in the electrolytic solution, these methods all cannot be implemented.
Therefore, a kind of method of effectively supercapacitor structures being reinforced is needed, to make it to use on aviation airborne equipment.
Summary of the invention
Goal of the invention: provide a kind of method that super capacitor is reinforced, strengthens the tolerance of super capacitor to vibration, super capacitor is used on airborne electronic equipment.
Technical scheme: a kind of super capacitor reinforcement means, comprises the following steps:
Step one: before electric capacity core body 15 loads aluminium shell 11, is first wound around a circle rubber slab 17 by outer for electric capacity core body 15, then puts into aluminium shell 11;
Step 2: pour into electrolyte, then by aluminium shell 11 crimping fastening blank cover 13, completes preliminary encapsulation;
Step 3: packaged capacitor is put into pressing tongs 18, electric capacity aluminium shell 11 is extruded several pits by pressing tongs 18, pit clamping electric capacity core body 15;
Step 4: as required, mobile pressing tongs 18 is local to other of super capacitor aluminium shell 11, repeats step 3, completes the reinforcing of electric capacity.
Beneficial effect: the present invention to the extruding of aluminium shell, make aluminium shell tightly block core body, under avoiding vibration environment, core body rocks in the enclosure, makes common aluminum hull super capacitor be provided with the ability tolerating long-time strong vibration., through aircraft actual vibration verification experimental verification, there is not damaged condition, can use on airborne electronic equipment, meet the specific demand of aviation field completely in the ultracapacitor after adopting the method to reinforce.

Embodiment
Be described in further detail below in conjunction with a kind of embodiment of accompanying drawing to invention, refer to Fig. 1 to Fig. 3.
The present invention is directed to the gap existed between super capacitor shell and core body, by applying pressure to some point of shell, making aluminium shell produce the fastening core body of pit.Rack core surface insulating barrier in order to avoid aluminium case pres-sure is excessive and cause short circuit, being wound around one deck rubber slab in core body outside.
For ultracapacitor as shown in Figure 1, its original typical assemble sequence, for load in aluminium shell 11 by electric capacity core body 15, pours into electrolyte, blank cover 13 is put into aluminium shell 11 and compresses, then by aluminium shell 11 crimping fastening blank cover 13.
One embodiment of the invention, when carrying out reinforcing enforcement, step is as follows:
Step one: before electric capacity core body 15 loads aluminium shell 11, is first wound around a circle rubber slab 17 by outer for electric capacity core body 15, then puts into aluminium shell 11; Rubber slab 17 1 aspect plays insulating effect, and on the other hand, that can cushion when pressing tongs 18 extrudes electric capacity aluminium shell is stressed, avoids excessive extrusion to cause the damage of electric capacity aluminium;
Step 2: pour into electrolyte, then by aluminium shell 11 crimping fastening blank cover 13, completes preliminary encapsulation;
Step 3: packaged capacitor is put into pressing tongs 18, electric capacity aluminium shell 11 is extruded several pits in the first half of electric capacity aluminium shell 11 by pressing tongs 18, pit clamping electric capacity core body 15; In the present embodiment, extrude 4 pits at electric capacity aluminium shell 11, concrete quantity is determined according to demand, is generally no less than two, also too much unsuitable, avoids the structural strength affecting electric capacity aluminium shell;
Step 4: as required, move down pressing tongs 18, and local to other of super capacitor aluminium shell 11, repeat step 3, upper and lower several groups of pits can fully clamp electric capacity core body 15, complete the reinforcing of electric capacity.
The present invention to the extruding of aluminium shell, make aluminium shell tightly block core body, under avoiding vibration environment, core body rocks in the enclosure, makes common aluminum hull super capacitor be provided with the ability tolerating long-time strong vibration., through actual vibration verification experimental verification, there is not damaged condition, can use on airborne electronic equipment, meet the demand of aviation field completely in the ultracapacitor after adopting the method to reinforce.
