[0026] The following will be described in detail below with reference to the accompanying drawings. Figures 1-6 The utility model will be described in further detail.

[0027] At present, the thickness of the electrode sheet 1 on the market is about 2mm, and the outer diameter of the electrode sheet 1 is about 25mm.

[0028] The utility model discloses a high-voltage capacitor lead-out electrode device.

[0029] Reference Figure 1 , including two electrode sheets 1, two electrode columns 2 and a capacitor base body 3, the two electrode sheets 1 adopt red copper material, the two electrode columns 2 adopt internal hexagonal brass columns, adopt brass material, the outer surfaces of the two electrode columns 2 are all fixedly connected to the inside of one end of the corresponding electrode sheet 1, and the outer surfaces of the other ends of the two electrode sheets 1 are all fixedly connected to the upper and lower sides of the capacitor base body 3 respectively.

[0030] Reference Figure 1 , the outer diameter of the two electrode sheets 1 is d1, and the outer diameter of the capacitor base body 3 is d2, and 2d1≤d2.

[0031] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 The two electrode sheets 1 all include hexagonal columns 11, circular truncated cone columns 12 and ring pieces 13, the two ends of the two circular truncated cone columns 12 are connected to the corresponding hexagonal columns 11 and ring pieces 13 respectively, the internal hexagonal brass electrode column 2 and the lead-out electrode sheet 1 are stamped together, and then are welded by using solder, the two electrode columns 2 are connected to the inside of the corresponding hexagonal columns 11 by stamping, and one side of the two ring pieces 13 is fixedly connected to the capacitor base body 3.

[0032] Reference Figure 3 The chamfer of the two electrode sheets 1 is C4, and the two ends are R1, the area is relatively large, the electric field is more easily balanced, and the electric uniformity inside the high-voltage electric field can be effectively improved.

[0033] Reference Figure 3 The thickness of the electrode sheet 1 is 0.5mm, when the material is relatively thin, the distribution of the electric field intensity and the electric displacement is relatively uniform, and it is not easy to concentrate in a local area, 40mm≤d1≤60mm, the surface area of the electrode sheet 1 is increased, and it is beneficial to improve the heat dissipation efficiency.

[0034] The outer surfaces of the two electrode plates 1, two electrode posts 2, and capacitor substrate 3 are plated with silver after being connected. After the two electrode plates 1, two electrode posts 2, and capacitor substrate 3 are fabricated as a whole, their surfaces are plated with silver. The conductivity of silver is 6.30×10^7 S / m, the conductivity of copper is 5.96×10^7 S / m, the resistivity of silver is 1.59×10^-8 Ω·m, and the resistivity of copper is 1.72×10^-8 Ω·m, thereby effectively improving the conductivity.

[0035] Reference Figure 5 , Figure 6 The electrode post 2 has a threaded hole inside. After the electrode sheet 1 and the capacitor ceramic substrate are bonded together, the outer end face of the lead-out electrode is machined by a lathe to ensure the parallelism of the two outer surfaces of the lead-out electrode and the accuracy of the distance between the two outer surfaces, thereby reducing the installation difficulty and making it easier to adapt to different high voltage generators.

[0036] The implementation principle of the high-voltage capacitor lead-out electrode device in this embodiment of the utility model is as follows:

[0037] 1. After the two electrode plates 1, two electrode posts 2 and capacitor base 3 are fabricated as a whole, they are placed under the guide plate of the high voltage generator. The bolts are screwed through the guide plate into the threaded holes opened inside the electrode posts 2, thereby quickly fixing the two electrode plates 1, two electrode posts 2 and capacitor base 3 onto the high voltage generator.

[0038] 2. The thickness of electrode sheet 1 is 0.5 mm. When the material is thinner, the distribution of electric field strength and electric displacement is more uniform and less likely to concentrate in local areas, thus avoiding uneven distribution of electric field strength. At the same time, 40 mm ≤ d1 ≤ 60 mm increases the surface area of ​​electrode sheet 1, which is beneficial to improving heat dissipation efficiency.

[0039] 3. Electrode 1 is relatively larger than the electrode 1 in the technical background. When connecting to different high-voltage generators, if any incompatibility is found, the size of electrode 1 and the parallelism of the two outer surfaces can be adjusted by machining on a lathe, thereby improving the accuracy of the distance between the two outer surfaces, reducing the installation difficulty, and improving the installation accuracy.

Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
