An impulse voltage generator is mainly used, and the ignition device in the impulse voltage generator is mainly composed of two graphite balls. In actual use, at the moment when the graphite ball is energized, the graphite powder on the surface of the graphite ball is lifted up, so that electricity is passed between the two graphite balls.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a voltage generating device for component impact testing, such as Figure 1 and 2 As shown, it includes a support 1, an ignition component 2 and an arc blowing component 3.

[0035] In order to adapt to components of different sizes, the lifting motor 23 is started, and the lifting motor 23 drives the driving gear 24 to rotate, driving the driving rack 25 to move up and down, and the driving rack 25 carries the lifting platform 28 and the first graphite ball 21 to move up and down, so as to adjust the distance between the first graphite ball 21 and the second graphite ball 22. The support 1 is also fixedly connected with a limit sleeve rod 26, which is sleeved on the outside of the driving rack 25. When the driving rack 25 moves up and down, the driving rack 25 is limited to ensure the moving stability of the driving rack 25, thereby ensuring the adjustment stability of the first graphite ball 21.
