Description

technical field [0001] The invention relates to an arc-shaped high-voltage electrode capable of generating a simulated upward leader, and belongs to the technical field of lightning protection research. Background technique [0002] In the process of studying lightning strikes on ground objects, scientific researchers often need to carry out simulation experiments. In the experiment, high-voltage electrodes will be applied with extremely high voltage to simulate lightning, and the field strength is extremely large. However, the high-voltage electrode used in the traditional experiment has a very weak surface field strength induced on the low-voltage side object due to the geometric shape of the electrode, which fails to achieve the purpose of simulating the upward leader; and the improved flat high-voltage electrode (a kind that can generate The high-voltage electrode that simulates the upward pilot, application number 201110304013.4), although the surface field strength ind...

AI Technical Summary

Problems solved by technology

[0005] 1. In this patent, when the distance between the high-voltage side and the low-voltage side is large, the size of the plate electrode required is relatively large, and it is difficult to eliminate its own edge effect by using traditional pressure equalization methods (such as pressure equalization rings, polishing, etc.), so that Discharge often occurs at the edge of the plate

[0006] 2. Although the larger plate electrode in this patent uses a spider web structure, it is light and convenient to hang, but after long-term use, the plate structure is still easy to deform and bend, and the huge plate is also difficult to process

[0007] 3. The uncertainty of the discharge position of the plate electrode makes observation more difficult. Although the patent installs a rod electrode on the plate electrode to solve this problem, the existence of the rod electrode makes the development conditions of the negative polarity streamer sufficient. As a result, the spatial field strength is distorted, which is not conducive to the development of the upward leader

[0008] In summary, although the existing high-voltage electrode shape can meet the needs of shielding simulation experiments in some aspects, there is still a lot of room for improvement
