Abstract
The utility model relates to a kind of capacitor from explosion structure, including the first connecting plate and the second connecting plate, first connecting plate and the setting of second connecting plate interval are connected between first connecting plate and the second connecting plate by rupture disc assembly spot-welded together.The utility model uses mechanical stretching formula blast resistance construction, draws the two poles of the earth by one group of spot welding safety plate, stroke is the deformational displacement amount of ontology body, when body deformation quantity reaches predetermined amount, the copper sheet of spot welding is pulled off, and formation is normally opened, and capacitor is just cut off from power grid at this time, it is explosion-proof to achieve the purpose that, not only explosion-proof is played, but also avoids the flow area at weak spot small, through-current capability is weak, cause calorific value big, the short problem of life of product.
Description
Technical field
The utility model relates to capacitor arrangement design fields, and in particular to a kind of capacitor from explosion structure.
Background technique
Chinese patent CN204633342U discloses a kind of intelligent capacitor and its anti-explosion mechanism, the intelligent capacitor packet
It includes shell and is set to the intracorporal anti-explosion mechanism of the shell, the anti-explosion mechanism has weak spot, the control of the intelligent capacitor
Explosion-proof signal acquisition circuit is provided in circuit processed, the weak spot is set in the explosion-proof signal acquisition circuit.It is Chinese special
Sharp 204884880 U of CN discloses the explosion-protection equipment in a kind of capacitor, is arranged on one or two boss on first substrate
There is first substrate kidney slot, safety plate one end at the first substrate kidney slot is by being arranged in first substrate kidney slot
Rivet is connect with boss, and rivet can be in first substrate kidney slot freely before " V " font scissors mouth of safety plate is broken by force
Back-and-forth motion.By using above scheme, the utility model overcomes the shortcomings of the prior art, and it is explosion-proof to provide a kind of change
Wherein a boss breaks stroke in substrate in device, can effectively reduce the explosion-proof pulling force of explosion-protection equipment, to reach anti-
Explosion-protection equipment for the purpose of quick-fried in novel capacitor.
But above-mentioned is all to be adopted on safety plate using mechanical explosion structure by the way that pulling force weak spot is arranged in the loop
With notch mode, when shell deformation, disconnected at weak spot, there are the shortcomings that are as follows: the flow area at weak spot is small, through-flow energy
Power is weak, and calorific value is big, and life of product is caused to shorten.
Utility model content
The purpose of this utility model is exactly to provide a kind of capacitor from explosion structure to solve the above-mentioned problems.
The purpose of this utility model is achieved through the following technical solutions:
A kind of capacitor from explosion structure, including the first connecting plate and the second connecting plate, first connecting plate and described
The setting of two connecting plate intervals, is connected between first connecting plate and the second connecting plate by rupture disc assembly spot-welded together
It connects.
Further, the rupture disc assembly keeps spot welding pulling-out force, when capacitor breaks down, the safety plate group
Part deforms with formation pressure in shell, pulls open at spot welding.
Further, the rupture disc assembly includes two identical L-type sheet metals, the L-type sheet metal company of welding back-to-back
Together.
Further, the L-type sheet metal uses copper sheet.
Further, the rupture disc assembly is equipped with two groups.
Further, the rupture disc assembly is by rivet on first connecting plate and the second connecting plate.
Further, first connecting plate and the second connecting plate are isolation material plate.
Further, the edge of first connecting plate and the second connecting plate is equipped with supporter.
Further, the supporter is L-type sheet metal, is riveted on first connecting plate and the second connecting plate.
A kind of capacitor contains above-mentioned capacitor from explosion structure.
It is designed on safety plate using notch with existing, the mode of setting pulling force weak spot is compared, and the utility model uses
Mechanical stretching formula blast resistance construction draws the two poles of the earth by one group of spot welding safety plate, and stroke is the deformational displacement amount of ontology body, works as shell
Figure variable reaches predetermined amount, and the copper sheet of spot welding is pulled off, and formation is normally opened, and capacitor is just cut off from power grid at this time, to reach
Explosion-proof purpose has been arrived, explosion-proof is not only played, but also has avoided the flow area at weak spot small, through-current capability is weak, causes to generate heat
Amount is big, the short problem of life of product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the bottom view of Fig. 1；
Fig. 3 is the side view of Fig. 1；
In figure: the first connecting plate of 1-；The second connecting plate of 2-；3- rupture disc assembly；4- supporter；5- rivet.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
