主要組成部件

本體扇形結構

本體電容器采用扇形結構，電容器垂直放置， 底部連接固定；

本體電容器采用扇形向心對稱結構，從結構上確保每組電容器距離放電間隙距離相同，很好地保證放電電流的均勻性。在長期使用中這樣的結構設計可以保證電容器使用壽命均勻，從而延長了設備壽命。

電容器可以單組運行，也可以并聯運行，手動換接電路比較方便。每組電容器放電過程中均串聯電阻，能夠保證電容器安全運行。

Main Components

Body Sector Structure

The body capacitor adopts a sector structure, capacitor is placed vertically, and bottom is connected and fixed;

The body capacitor adopts a fan-shaped centripetal symmetrical structure to ensure that each group of capacitors is at the same distance from the discharge gap to ensure the uniformity of the discharge current to the greatest extent. In long-term use, such a structural design can ensure the uniform life of the capacitor, thereby prolonging the life of the device.

Capacitors can be operated in a single group or in parallel, and it is more convenient to switch the circuit manually. Each group of capacitors are connected in series with resistors during the discharge process, which can ensure the safe operation of the capacitors.
