[0003] The patent application with the application number CN202010443303.6 discloses an intelligent low-voltage power capacitor based on a dry capacitor, including a housing. Heat dissipation grids are evenly arranged on both sides of the housing. External connection terminals are arranged on the upper end surface of the housing through an external cover plate.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Example 1: Refer to Figures 1 - 4, the present invention provides a technical solution: a low-power static power capacitor, including a housing 1. A connecting column 101 is fixedly connected to the bottom of the housing 1, and a motor 102 is fixedly connected to the top of the housing 1. A circular hole 103 is provided on the outer wall of the housing 1, and an insertion hole 104 is provided on the inner wall of the circular hole 103. A capacitor 105 is movably connected to the inner wall of the circular hole 103. One end of the capacitor 105 close to the housing 1 is fixedly connected to a connecting column 106. The outer wall of the connecting column 106 is movably connected to the insertion hole 104, and a locking hole 107 is provided on the outer wall of the insertion hole 104. When the device needs to replace the damaged capacitor 105, only the damaged capacitor 105 needs to be pulled out from the circular hole 103, and then the new capacitor 105 is put into the circular hole 103.

[0024] Embodiment 2: Please refer to Figures 5 - 10 , on the basis of Embodiment 1, the present invention provides a technical solution: an internal mechanism 2. The internal mechanism 2 includes a central column 201 rotatably connected to the inner wall of the housing 1 through a bearing. The output end of the motor 102 is fixedly connected to the central column 201. A connecting plate 202 is fixedly connected to the outer wall of the central column 201, and a connecting plate 203 is fixedly connected to the outer wall of the central column 201. An elastic component 2011 is fixedly connected to the inner wall of the connecting plate 203. A track 2012 is fixedly connected to the outer wall of the central column 201. A movable component 21 is movably connected to the outer wall of the track 2012. A connecting component 22 is fixedly connected to the inner wall of the housing 1, and an auxiliary component 23 is more connected to the inner wall of the housing 1. The central column 201 rotates under the drive of the motor 102 to control the orientation of the movable component 21. A connecting wire 204 is fixedly connected to the inner wall of the central column 201, and a connecting wire 205 is fixedly connected to the inner wall of the central column 201. A brush 206 is fixedly connected to the bottom of the connecting wire 204, and a brush 207 is fixedly connected to the bottom of the connecting wire 205. A bracket 208 is fixedly connected to the inner wall of the housing 1, and a power-on ring 209 is fixedly connected to the inner wall of the bracket 208. The inner wall of the brush 207 is movably connected to the power-on ring 209, and the inner wall of the brush 206 is movably connected to the power-on ring 209. A connecting column 2010 is fixedly connected to the outer wall of the power-on ring 209. The bottom of the connecting column 2010 is fixedly connected to the connecting column 101. When it is detected that the capacitor 105 in the connected circuit is damaged, the motor 102 will drive the central column 201 to rotate. As the central column 201 rotates, the position of the movable component 21 will deflect. The deflected movable component 21 will connect the circuit to the next capacitor 105. At the same time, as the central column 201 rotates, it will deflect through the connecting wire 204 and the connecting wire 205. However, when the connecting wire 204 and the connecting wire 205 deflect, the brush 206 and the brush 207 will still be connected to the power-on ring 209 to ensure that the connection of the bottom circuit of the device will not be interrupted.

[0025] Embodiment 3: Please refer to Figures 10 - 12 , on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: The movable component 21 includes a first U-shaped plate 211. The outer wall of the track 2012 is movably connected to the first U-shaped plate 211. A first energizing plate 212 is fixedly connected to the inner wall of the first U-shaped plate 211. One end of the first connecting wire 204 away from the first brush 206 is movably connected to the first energizing plate 212. One end of the second connecting wire 205 away from the second brush 207 is movably connected to the first energizing plate 212. A convex plate 213 is fixedly connected to the inner wall of the first U-shaped plate 211. When the convex plate 213 is subjected to pressure, it plays a role in controlling the height of the movable component 21. A first energizing head 215 is fixedly connected to the inner wall of the first U-shaped plate 211. A sliding column 214 is fixedly connected to the top of the first U-shaped plate 211. A second energizing head 216 is fixedly connected to the top of the sliding column 214. The outer wall of the sliding column 214 is movably connected to the first connecting plate 202. A spring 217 is sleeved on the outer wall of the sliding column 214. The top of the spring 217 is fixedly connected to the second energizing head 216. The bottom of the spring 217 is fixedly connected to the first connecting plate 202. The bottom of the first U-shaped plate 211 is fixedly connected to the elastic component 2011. As the central column 201 deflects, the convex plate 213 loses the support of the connecting component 22. Under the elasticity of the spring 217 and the elastic component 2011, the first U-shaped plate 211 moves upward. The moving first U-shaped plate 211 will drive the second energizing head 216 to be connected to the auxiliary component 23 through the sliding column 214. As the central column 201 continues to deflect, the convex plate 213 will be squeezed by the movable component 21 again, driving the first U-shaped plate 211 to move downward. At this time, the second energizing head 216 is no longer connected to the auxiliary component 23, and the first energizing head 215 at the bottom is connected to the connecting component 22.

[0026] The connecting component 22 includes a first annular plate 222. The outer wall of the first annular plate 222 is fixedly connected with a second U-shaped plate 221. The inner wall of the housing 1 is fixedly connected with the second U-shaped plate 221. A second round hole 225 is formed in the outer wall of the second U-shaped plate 221. The inner wall of the second round hole 225 is movably connected with a second connecting column 106. The outer wall of the first annular plate 222 is fixedly connected with a power-on strip 224. One end of the power-on strip 224 away from the annular plate is fixedly connected with the second U-shaped plate 221. A lifting plate 223 is fixedly connected to the side of the first annular plate 222 away from the power-on strip 224. The lifting plate 223 is used to apply pressure to the protruding plate 213, so as to change the position of the movable component 21. An elastic plate 226 is movably connected to the inner wall of the second U-shaped plate 221. A locking head 227 is fixedly connected to the outer wall of the elastic plate 226. The locking head 227 penetrates through the U-shaped plate and extends to the inner wall of the second round hole 225. The outer wall of the locking head 227 is movably connected with the second U-shaped plate 221. The outer wall of the locking head 227 is movably connected with a locking hole 107. As the central plate deflects, the lifting plate 223 will apply pressure to the protruding plate 213, and then change the height of the movable component 21. When the device needs to replace the damaged first capacitor 105, the first capacitor 105 is removed and a new first capacitor 105 is inserted. At this time, the locking head 227 will be embedded in the locking hole 107 under the elastic force of the elastic plate 226 to complete the fixation of the first capacitor 105.

[0027] The auxiliary component 23 includes a second annular plate 233. The outer wall of the second annular plate 233 is fixedly connected with a side plate 231. The inner wall of the housing 1 is fixedly connected with the side plate 231. A second capacitor 232 is fixedly connected to the inner wall of the side plate 231. A connecting ring 234 is fixedly connected to the side of the second annular plate 233 away from the housing 1. A second power-on plate 235 is fixedly connected to the side of the connecting ring 234 away from the second annular plate 233. When the movable component 21 is not squeezed by the lifting plate 223, the second power-on head 216 will be in contact with the second power-on plate 235 to complete the connection between the movable component 21 and the auxiliary component 23. At this time, the current will enter from above, pass through the second capacitor 232, and then flow out from the second power-on plate 235 below.
