[0002] The impulse voltage generator wave modulation RC device is a device used to generate high-voltage pulses with specific frequency and waveform. It is usually used in the fields of testing, measurement and protection in power systems. The impulse voltage generator wave modulation RC device has important applications in power system testing, equipment detection and scientific research. It can provide high voltage, high frequency and specific waveform pulse signals, providing necessary support for experiments and applications in related fields.

[0003] However, most of the current impulse voltage generator wave modulation resistance and capacitance devices have the following problems:

[0004] For example, an impulse voltage generator wave modulation device with publication number CN213181872U, although the rollers on the base can be used to easily push the device to the use position, the device needs to be placed aside for use during use, and the contact area between the rollers and the ground is limited. If it is bumped by external force or affected by the ground environment, it is easy to cause the device to slide and deviate, affecting the stability of the device, and it is inconvenient to conveniently support the device and place it aside for use; the wave modulation resistor and pulse capacitor installed at the same time are connected and used by nuts, etc., but when they need to be disassembled, multiple bolts need to be disassembled, which is time-consuming and inconvenient to conveniently install and disassemble the wave modulation resistor and pulse capacitor.

[0005] Therefore, we make improvements on this and propose a surge voltage generator with a RC device. Utility Model Content

[0032] Embodiment 2:

[0033] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0034] like Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the rotating member 3 is fixedly connected to the center of the first gear 4, and the center line of the first gear 4 and the center line of the second gear 5 are on the same horizontal line, which can ensure that when the first gear 4 is running, it can drive the second gear 5 on the same horizontal line to run at the same time.

[0035] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the second gear 5 is symmetrically distributed on the left and right sides of the first gear 4, and the second gear 5 corresponds one-to-one with the threaded rod 7 through the threaded sleeve 6, which can ensure that the movement of the threaded rod 7 on both sides can smoothly push the support plate 8 to move up and down.

[0036] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the limit plate 12 is fitted with the inner side face of the mounting plate 10, and the side end cross-section of the clamping block 13 is inclined, which can ensure that when the limit plate 12 moves, it can move smoothly with the support of the inner side face of the mounting plate 10.

[0037] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, a wave modulation resistor 16 is provided on one side of the mounting plate 10, and a connecting plate 17 is installed on the pulse capacitor 15 and the wave modulation resistor 16, and the bottom side end surface of the connecting plate 17 is inclined, which can ensure that the inclined surface of the connecting plate 17 can smoothly push the inclined block 13 to move.

[0038] Specifically, when the impulse voltage generator wave modulation resistor and capacitor device is used: Figure 1-5 When the impulse voltage generator is modulated with resistors and capacitors, the cart 1 can be pushed to move to the operation site. In order to prevent the cart 1 from sliding and affecting the operational stability, the rotating parts 3 on the protective shells 2 on both sides can be rotated, and the rotating parts 3 drive the first gear 4 to operate. When the first gear 4 rotates, it can smoothly drive the threaded sleeve 6 to operate through the second gear 5. When the threaded sleeve 6 rotates, it can push the threaded rod 7 connected by the thread to move. When the threaded rod 7 moves downward, it can cooperate with the support plate 8 to support the cart 1, thereby improving the stability of the cart 1 and avoiding shaking caused by external forces. When the cart 1 needs to be moved later, the threaded sleeve 6 can be driven in the opposite direction to operate, and the threaded sleeve 6 drives the threaded rod 7 to move upward.

When the limit plate 12 moves, the block 13 can be retracted into the mounting plate 10, and the limit plate 12 squeezes the spring 11, and the block 13 is detached from the connecting plate 17 on the pulse capacitor 15 or the wave-modulating resistor 16.
