[0002] The arc generator is a device used to improve researchers' understanding of current waveforms. It can generate various random current waveforms. Normal alternating current is a sinusoidal waveform. When an electrical fault occurs, the current waveform will produce various random waveforms due to leakage and circuit breakage. The arc generator makes it easy for researchers to analyze the various operating waveforms of the current and eliminate the fault in a timely manner.

[0003] The existing arc generator can drive the copper rod on the transmission seat to approach the carbon rod by turning the adjustment knob. The transmission seat and the transmission rod are connected by trapezoidal thread transmission, so that the carbon rod and the copper rod reach the effective distance for arc generation. However, when it is operated, the transmission seat may move too fast when the adjustment knob is turned, which may cause the arc to break and affect observation. In view of this, the utility model proposes a fine-tunable arc generator. Utility Model Content

[0026] Example

[0027] like Figure 1 As shown, the utility model provides a fine-adjustable arc generator, including a base 1, two sets of vertical plates 2 are symmetrically arranged on the top of the base 1, and the base 1 and the vertical plates 2 are both made of bakelite. Three sets of observation plates 3 are fixedly mounted on the vertical plates 2 by screws, and the observation plates 3 are made of transparent acrylic plates, which are convenient for observing the arc situation.

[0028] For details, please refer to Figure 2 The arc generator includes a generating mechanism 4 for generating an arc, which is arranged on the base 1. The generating mechanism 4 includes a copper rod 41 and a carbon rod 42. The generating mechanism 4 also includes a guide rod 43, a movable plate 44, and a mounting seat 45. The two sets of guide rods 43 are fixedly connected between the two sets of vertical plates 2, and the position of the guide rods 43 is fixed. The movable plate 44 is slidably connected to the two sets of guide rods 43, and the movable plate 44 moves smoothly under the limiting action of the two sets of guide rods 43. A mounting seat 45 is installed on the side opposite to the movable plate 44 of a set of vertical plates 2. The copper rod 41 is installed in the carbon rod 42 arranged on the side of the movable plate 44, and the carbon rod 42 is installed in the mounting seat 45 arranged on the side of the vertical plate 2. The copper rod 41 and the carbon rod 42 are both detachably installed in the mounting seat 45. The copper rod 41 is made of copper, and the carbon rod 42 is pressed from carbon powder, and needs to be replaced when it is worn. The generating mechanism 4 also includes a threaded rod 46 rotatably connected between the two sets of vertical plates 2, and the threaded rod 46 rotates in place. The threaded rod 46 is threadedly connected to the moving plate 44 . When the threaded rod 46 rotates, it drives the moving plate 44 to move along the length direction of the threaded rod 46 .

[0029] Further, such as Figure 3-Figure 5 As shown, the arc generator further includes an adjustment component 5 for adjusting the distance between the copper rod 41 and the carbon rod 42. The adjustment component 5 includes a mounting hole 51, a bearing 52, and a rotating ring 53. The mounting hole 51 is provided on the vertical plate 2 on the side of the movable plate 44 away from the mounting seat 45. The bearing 52 is mounted on the inner wall of the mounting hole 51, and the rotating ring 53 is mounted in the bearing 52. The bearing 52 enables the rotating ring 53 to rotate in the original position. One end of the threaded rod 46 is fixedly connected to the rotating ring 53. When the rotating ring 53 rotates, it drives the threaded rod 46 to rotate. The adjustment component 5 also includes an inner gear ring 54, a first gear 55, a positioning column 56, and a fixing plate 57. The inner gear ring 54 is mounted on the inner ring of the rotating ring 53. The inner gear ring 54 rotates synchronously with the rotating ring 53. The four groups of first gears 55 are all arranged on the inner side of the inner gear ring 54 and mesh with it. When the first gear 55 rotates, it drives the inner gear ring 54 to rotate. The positioning column 56 is rotatably connected to the first gear 55, the fixing plate 57 is fixedly connected to one end of the plurality of positioning columns 56 away from the rotating ring 53, and the fixing plate 57 is fixedly connected to the mounting hole 51, and is used to fix the position of the first gear 55, so that the first gear 55 keeps rotating in the original position. The adjustment assembly 5 also includes a connecting rod 58 and a second gear 59, the connecting rod 58 is rotatably connected to the fixing plate 57, and the second gear 59 is fixedly connected to one end of the connecting rod 58, and the connecting rod 58 drives the second gear 59 to rotate when rotating. The second gear 59 is meshed with the four groups of first gears 55, and the second gear 59 drives the four groups of first gears 55 to rotate when rotating, so that the inner gear ring 54 rotates synchronously, thereby realizing the rotation of the rotating ring 53. An adjusting knob is also installed at one end of the connecting rod 58 away from the second gear 59, which is convenient for rotation. At the same time, the adjusting knob drives the threaded rod 46 to rotate slowly, so that the moving plate 44 moves slowly, which is convenient for fine adjustment.

[0030] In this embodiment, when the adjusting knob is turned, the adjusting knob drives the second gear 59 to rotate through the connecting rod 58, and the second gear 59 drives the four groups of first gears 55 to rotate in the original position under the limiting effect of the positioning column 56. Therefore, the second gear 59 drives the inner gear ring 54 to rotate through the four groups of first gears 55, and the inner gear ring 54 drives the rotating ring 53 to rotate smoothly under the limiting effect of the bearing 52, so that the rotating ring 53 drives the threaded rod 46 to rotate. At the same time, when the adjusting knob rotates one circle, the threaded rod 46 rotates less than one circle, and the threaded rod 46 rotates relatively slowly, which is convenient for the slow movement of the moving plate 44 for fine adjustment. When the threaded rod 46 rotates, it drives the moving plate 44 to move smoothly under the limiting effect of the two groups of guide rods 43. Thus, the distance between the copper rod 41 and the carbon rod 42 is controlled. When the two sets of mounting seats 45 are connected to alternating current, when the distance between the copper rod 41 and the carbon rod 42 is very close, electric sparks will be generated between the two. The closer the distance, the stronger the electric sparks, thereby generating currents of different waveforms in the circuit loop. At the same time, the staff can observe the electric sparks through the three observation boards 3.

[0031] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
