along with the rise of the temperature, the bending deformation of the heat-sensitive bimetallic strip 3 is increased, and further the distance of the rack I5 driven by the connecting rod 4 to move upwards is increased, so that the angle of the rotating shaft 17 driven by the gear 9 to rotate around the shaft rod 8 is increased, the angle of the rotating shaft 17 driven by the gear ring 11 and the rotating rod 16 to rotate around the shaft rod 8 is increased, further the distance between the heat-radiating plate 10 and the shell 1 is increased, so that the air circulation efficiency is increased in a self-adaptive manner, the heat-radiating effect is improved, in the process that the gear ring 11 rotates around the shaft rod 8, after the gear ring 11 is meshed and connected with the rack II 12 on the bracket 7, the gear ring 11 rotates around the rotating shaft 17 under the tooth transmission effect between the gear ring 11 and the rack II 12, further the gear ring 11 drives the rotating rod 16 and the heat-radiating plate 10 to synchronously rotate around the rotating shaft 17, namely, the heat-radiating, the rotation of the heat dissipation plate 10 on two axes enables the heat dissipation plate 10 to start stirring action on air around the shell 1, and the flow of the air is promoted, so that the heat dissipation efficiency of the shell is improved, and the heat of the capacitor works on the heat dissipation plate 10 through the heat-sensitive metal sheet 3, the connecting rod 4, the first rack 5, the gear 9, the rotating shaft 17, the gear ring 11 and the rotating rod 16, so that the heat is consumed, and the heat dissipation efficiency and the effect of the automatic heat dissipation device for the capacitor in the application are increased;
after the heat generated by the heat dissipation plate 10 to the capacitor is dissipated or the working power of the capacitor is reduced, the heat is reduced, or the capacitor stops working and does not generate heat any more, so that the heat-sensitive bimetallic strip 3 is heated and reduced, the heat-sensitive bimetallic strip 3 is reset from a bent state to a straight state after being cooled, the lower end of the heat-sensitive bimetallic strip is close to the outer side wall of the shell 1, the rack I5 is driven by the connecting rod 4 to move downwards and reset under the guiding action of the sliding sleeve 6, the downward movement of the rack I5 drives the gear 9 to rotate around the shaft rod 8 in the reverse direction through the tooth transmission action between the rack I5 and the gear 9, the gear 9 rotates around the shaft rod 8 in the reverse direction and simultaneously drives the rotating shaft 17 to rotate around the shaft rod 8 in the reverse direction, the reverse rotation of the rotating shaft 17 synchronously drives the gear ring 11 and the rotating rod 16 to rotate around the shaft rod 8 in the, and reset, in the course that the gear ring 11 rotates around the shaft lever 8 in the opposite direction, the tooth transmission action between gear ring 11 and rack two 12 makes the gear ring 11 rotate around the axis of rotation 17 in the opposite direction, and then make the gear ring 11 drive the rotating lever 16 and heat-dissipating plate 10 to rotate around the axis of rotation 17 in the opposite direction synchronously, namely realize the heat-dissipating plate 10 rotates around the axis of rotation 17 in the opposite direction too while rotating around the shaft lever 8 in the opposite direction, and reset, thus realize the automatic reset, so that when the capacitor produces heat next time, the heat-dissipating plate 10 carries on the heat-dissipating treatment to the capacitor according to the above-mentioned movement state, wherein when the working condition of the capacitor, its output power is getting bigger or getting smaller, namely increase or reduction of the heat production, make the heat-dissipating plate 10 swing reciprocally, increase the air flow around the outer cover 1, thus realize;
step two: the heat generated after the capacitor works is transmitted to the cooling liquid through the inner shell 2, so that the temperature of the cooling liquid rises, the internal pressure is increased, the hot cooling liquid moves upwards, the conduction direction of the one-way valve I15 points to the inside of the heat dissipation plate 10, the conduction direction of the one-way valve II 19 points to the cavity between the outer shell 1 and the inner shell 2, therefore, the hot cooling liquid on the upper side inside the cavity enters the inside of the heat dissipation plate 10 through the liquid inlet pipe 14, the heat dissipation plate 10 conducts heat dissipation and temperature reduction on the high-temperature cooling liquid entering the inside of the heat dissipation plate 10, similarly, the conduction direction of the one-way valve I15 points to the inside of the heat dissipation plate 10, the conduction direction of the one-way valve II 19 points to the cavity between the outer shell 1 and the inner shell 2, therefore, the cooled cooling liquid flows back to the inside of the cavity through the liquid outlet pipe 19, further, the circulating flow of, the plurality of heat dissipation plates 10 are adopted to increase the heat dissipation area, so that the flow efficiency of cooling liquid is facilitated, the pressure of the heated cavity between the outer shell 1 and the inner shell 2 is kept stable while the heat dissipation efficiency is improved through the circulating flow of the cooling liquid, the technical requirement on high-temperature sealing performance is reduced, the production and the manufacture are easy, the processing difficulty is reduced, and the practicability is improved;

After the capacitor is powered off, the heat generated by the capacitor gradually decreases and returns to the original state, and at this time, the heat-sensitive bimetal 3 returns to the original state. In the process, the thermosensitive bimetallic strip 3 drives the rack I5 to move downwards and reset through the connecting rod 4, the downward movement of the rack I5 synchronously drives the upper lug 20 and the lower lug 21 to move downwards, so that the upper lug 20 exerts downward pressure on the left end of the sleeve 23 on the left in figure 5, according to the lever action, the left end of the sleeve 23 moves downwards, and the right end moves upwards, so that the corresponding slide bar 26 is driven to move upwards, the slide bar 26 moves upwards, the press block 27 is driven to move upwards through the pin head 25, and make the two sleeves 23 in splayed shape, return to the original state, make the pressure block 27 not contact with key switch 28 under the action of spring 26 at this moment, the key switch 28 is in an off state, and at the moment, an alarm circuit formed by the key switch 28, the storage battery 29 and the audible and visual alarm 30 is in an off state, so that the audible and visual alarm 30 does not give an alarm, the alarm is automatically released, and manual operation is not needed.
