In operation, when the capacitor is powered on, if no point discharge occurs at the burr between the aluminum bars 3, a mutually balanced position is formed among the first magnet 411, the second magnet 421, the vibrating body 41 and the spring 42; if the burrs between the aluminum bars 3 are opposite to each other, the point discharge occurs, so that the circuit is broken down and short-circuited; therefore, the vibrating body 41 is rotatably connected to the top end of the shell 1 through the rotating shaft, so that when the sharp discharge occurs to burrs between the aluminum bars 3, the vibrating body 41 is driven to vibrate and rotate, in the rotating process of the vibrating body 41, the second magnet 421 at the two ends of the vibrating body 41 rotates along with the vibrating body, and due to the fact that mutual repulsive force exists between the second magnet 421 and the first magnet 411 and the repulsive force is larger than the self elastic force of the spring 42, the spring 42 is subjected to elastic deformation of extension under the action of the repulsive force, and in the extending process of the spring 42, the spring 42 scrapes and brushes the burrs on the surface of the aluminum bars 3, so that the discharge phenomenon of the burrs is broken, the protection effect on a circuit is realized, and the use effect and the overall use safety of the capacitor are further enhanced; when burrs among the aluminum bars 3 are opposite to each other, point discharge occurs, so that a circuit is broken down, and the circuit is short-circuited; therefore, the vibrating body 41 is rotatably connected to the top end of the shell 1 through the rotating shaft, so that when the tip discharge of burrs between the aluminum rods 3 occurs, the vibrating body 41 is driven to vibrate and rotate, in the rotating process of the vibrating body 41, the vibrating body 41 drives the cam 52 to rotate through the rotating shaft, and as the vibrating rod 53 is in direct contact with the surface of the cam 52, the cam 52 pushes the vibrating rod 53 to knock the surface of the spring 42 while rotating, so that the vibration effect of the spring 42 is enhanced, the effect of scraping and brushing burrs on the surface of the aluminum rods 3 by the spring 42 is enhanced, and the tip discharge of the burrs is blocked, so that the whole circuit is protected, and the circuit elements are prevented from being damaged; when burrs among the aluminum bars 3 are opposite to each other, point discharge occurs, so that a circuit is broken down, and the circuit is short-circuited; therefore, the vibrating body 41 is rotatably connected to the top end of the shell 1 through the rotating shaft, so that when the tip discharge occurs to the burrs between the aluminum bars 3, the vibrating body 41 is driven to vibrate and rotate, in the rotating process of the vibrating body 41, the second magnet 421 at the two ends of the vibrating body 41 rotates along with the vibrating body, and because the mutual repulsive force exists between the second magnet 421 and the first magnet 411 and is greater than the self elastic force of the spring 42, the spring 42 is subjected to elastic deformation of extension under the action of the repulsive force, in the extension process of the spring 42, the spring 42 scrapes and brushes the burrs on the surface of the aluminum bar 3, so that the discharge phenomenon of the burrs is interrupted, but if the spring 42 is in direct contact with the surface of the aluminum bar 3 in the extension deformation process, the abrasion on the surface of the aluminum bar 3 is caused, so that the resistance and the transmission power of the aluminum bar 3 are changed, so that a fluff layer is arranged on the inner, the direct contact between the inner surface of the spring 42 and the surface of the aluminum bar 3 is avoided, so that the service life of the whole capacitor is ensured, and the working performance of the capacitor in the use process is improved; if the burrs between the aluminum bars 3 are opposite, the situation of point discharge can occur, so that the short circuit situation of the internal circuit of the capacitor is caused, and the outer ring of the aluminum bars 3 is set to be wavy, so that the situation of direct opposite of the burrs between the aluminum bars 3 is greatly reduced, the probability of point discharge between the burrs is effectively reduced, the damage of the internal circuit of the capacitor caused by point discharge is avoided, the service life of the capacitor is further prolonged, and great convenience is brought to a user; when the burrs between the aluminum bars 3 are subjected to point discharge, the vibrating body 41 is driven to vibrate and rotate, the second magnets 421 at the two ends of the vibrating body 41 rotate along with the vibrating body 41 in the rotating process of the vibrating body 41, and the repulsive force is larger than the self elastic force of the spring 42 due to the mutual repulsive force between the second magnets 421 and the first magnets 411, so that the spring 42 is subjected to elastic deformation of extension under the action of the repulsive force, and the spring 42 scrapes and brushes the burrs on the surfaces of the aluminum bars 3 in the extending process of the spring 42, so that the discharge phenomenon of the burrs is interrupted; because the magnetism of the end part of the magnetic bar 32 close to the aluminum bar 3 is opposite to that of the second magnet 421, when the spring 42 drives the second magnet 421 to extend and deform, the part of the magnetic bar 32 close to the end part of the aluminum bar 3 can vibrate under the action of mutual repulsion force, so that the electric balance in the aluminum bar 3 is damaged, the discharge phenomenon among burrs is broken, the circuit in the capacitor can be timely protected, and the failure of the capacitor is avoided; when the burrs between the aluminum bars 3 are subjected to point discharge, the vibrating body 41 is driven to vibrate and rotate, the second magnets 421 at the two ends of the vibrating body 41 rotate along with the vibrating body 41 in the rotating process of the vibrating body 41, and the repulsive force is larger than the self elastic force of the spring 42 due to the mutual repulsive force between the second magnets 421 and the first magnets 411, so that the spring 42 is subjected to elastic deformation of extension under the action of the repulsive force, and the spring 42 scrapes and brushes the burrs on the surfaces of the aluminum bars 3 in the extending process of the spring 42, so that the discharge phenomenon of the burrs is interrupted; because the magnetism that magnetic bar 32 is close to 3 tip of aluminium bar is opposite with the magnetism of No. two magnet 421, make spring 42 drive No. two magnet 421 take place the extension when warping, the part that magnetic bar 32 is close to 3 tip of aluminium bar can take place the vibration under the effect of mutual repulsion, and the position vibration range that magnetic bar 32 is close to 3 tip of aluminium bar is great, and the position vibration range that aluminium bar 3 tip was kept away from to magnetic bar 32 is less, thereby both guaranteed the shake effect of magnetic bar 32, also avoided magnetic bar 32 to influence the stability of 3 bottoms of aluminium bar at the shake in-process, thereby whole result of use and the life of aluminium bar 3 have been guaranteed.
