DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings. Example 1

[0025] A visual switch arc experimental device, such as Figure 1-Figure 3As shown, it includes a first mounting plate 1, to which a second mounting plate 2 is connected, an experimental box 3 is connected to the upper right side of the first mounting plate 1, and observation windows 31 are provided on the upper right side and the front side of the experimental box 3, a driving assembly 4 is provided on the upper left side of the first mounting plate 1, and the driving assembly 4 includes a driving motor, a main gear and a slave gear, a driving motor is installed on the upper left side of the first mounting plate 1, and the main gear is connected to the output shaft of the driving motor, the left side of the first mounting plate 1 is rotatably connected to the slave gear, and the slave gear is meshed with the main gear, a connecting rod assembly 5 is provided on the second mounting plate 2, and the left side of the connecting rod assembly 5 is connected to the slave gear, a pushing member 6 is slidably connected to the middle part of the second mounting plate 2, and the pushing member 6 is rotatably connected to the right side of the connecting rod assembly 5, and the The right part of the second mounting plate 2 is slidably connected with the first connecting member 7, the right part of the second mounting plate 2 is connected with the second connecting member 71, a spring 8 is connected between the first connecting member 7 and the second connecting member 71, a moving contact 9 is connected to the right side of the first connecting member 7, the right part of the experimental box 3 is slidably connected with the side panel 10, the side panel 10 is a detachable connection structure, the left side of the side panel 10 is connected with the static contact 11, the right part of the moving contact 9 is connected with the electromagnetic coil 12, and the left part of the static contact 11 is provided with a permanent magnet 13, and also includes: an adjusting mechanism 14, the adjusting mechanism 14 is arranged on the right part of the experimental box 3, so that the experimental device can use different distance test requirements; a recording mechanism 15, the recording mechanism 15 is arranged on the upper side of the right part of the experimental box 3, and can record the experimental process.

[0026] It should be noted that switching arc is a common phenomenon in electrical equipment, especially when switching devices such as circuit breakers and relays open or close the circuit, a high-temperature, high-energy arc will be generated between the contacts due to the sudden interruption or connection of the current. Switching arc experiments can study the generation, characteristics, extinguishing mechanism of arcs and their impact on equipment. When conducting the experiment, start the drive motor, and the output shaft of the drive motor rotates to drive the main gear to rotate, thereby driving the slave gear to rotate, so that the connecting rod assembly 5 moves, and then the pusher 6 moves to the right on the second mounting plate 2. The pusher 6 continues to move to the right, and will contact and squeeze the first connecting member 7, and the spring 8 is compressed. The spring 8 can ensure that the contact pressure between the moving contact 9 and the static contact 11 is moderate to avoid poor contact or excessive pressure. The first connecting member 7 will push the moving contact 9 to move during the movement, and the moving contact 9 will contact the static contact 11. Under the reaction force of the spring 8, the moving contact 9 will separate from the static contact 11, thereby simulating the closing and opening process of the switch. When the moving contact 9 is separated from the static contact 11, an arc will be generated between the contacts due to the sudden interruption of the current. The electromagnetic coil 12 will generate a magnetic field after being energized, which will interact with the magnetic field of the permanent magnet 13 to adjust the shape and intensity of the arc. The adjustment mechanism 14 can change the distance between the static contact 11 and the moving contact 9 to meet the arc experiment requirements under different voltage or current conditions. The recording mechanism 15 uses the camera 152 to take videos or pictures, and can record the test process for subsequent analysis and research.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the adjustment mechanism 14 includes a first connecting plate 141, the first connecting plate 141 is connected to the lower part of the side plate 10, the second connecting plate 142 is connected to the lower right side of the experimental box 3, the lower part of the second connecting plate 142 is rotatably connected to an adjusting screw 143, the adjusting screw 143 is provided with anti-slip grooves, and the adjusting screw 143 is threadedly connected to the first connecting plate 141.

[0028] It should be noted that when it is necessary to adjust the distance between the static contact 11 and the moving contact 9 to adapt to different arc test requirements, the adjusting screw 143 can be rotated to make the first connecting plate 141 move along the adjusting screw 143, thereby driving the side plate 10 to slide, thereby adjusting the side plate 10 and the static contact 11 to a suitable position, thereby adapting to the arc test requirements under different voltage or current conditions. Example 2

[0029] On the basis of Example 1, Figure 1 , Figure 2 and Figure 5As shown, the recording mechanism 15 includes a mounting frame 151, the mounting frame 151 is connected to the upper right side of the experimental box 3, a camera 152 is rotatably connected to the mounting frame 151, and fill lights 153 are provided on both the front and rear sides of the camera 152.

[0030] It should be noted that in order to better monitor and record the arc test process, the camera 152 can be adjusted to a suitable camera angle, and the fill light 153 can be used to illuminate the experimental process to ensure that the experimental phenomena can still be clearly recorded under insufficient light conditions, and the test process can be recorded for subsequent analysis and research.

[0031] like Figure 1 , Figure 2 and Figure 6 As shown, an arc extinguishing mechanism 16 is also included. The arc extinguishing mechanism 16 includes a first mounting seat 161. The middle of the experimental box 3 is connected to the first mounting seat 161. The first mounting seat 161 is connected to an arc extinguishing frame 162. The inner side of the arc extinguishing frame 162 is connected to a plurality of arc extinguishing beads 163.

[0032] It should be noted that when conducting arc experiments, due to the high arc temperature, it will damage the contact material and reduce the service life of the equipment. Arc extinguishing operation is required during the experiment. Arc extinguishing device 163 can divide the arc into multiple small segments, accelerate the cooling and extinguishing of the arc, thereby effectively reducing the damage of the arc to the experimental equipment and improving the safety of the experiment.

[0033] like Figure 1 , Figure 2 and Figure 7 As shown, the experimental box 3 further includes a guide mechanism 17 , which includes a second mounting seat 171 . The left portion of the experimental box 3 is connected to the second mounting seat 171 , and a cavity 172 is provided on the second mounting seat 171 .

[0034] It should be noted that, in order to enhance the stability and smoothness of the moving contact 9 during movement, the second mounting seat 171 and the cavity 172 provide guidance for the movement of the moving contact 9, ensuring that the moving contact 9 remains stable during movement and avoids deviation or jamming.

[0035] like Figure 1 , Figure 2 and Figure 8 As shown, a protective component 18 is also included, and the protective component 18 includes a rubber ring 181. The rubber ring 181 is connected to the right side of the push member 6, and a rubber block 182 is arranged on the left side of the rear of the first connecting member 7, which can prevent the first connecting member 7 from being damaged when it contacts the second mounting plate 2.

[0036] It should be noted that since impact may be generated when the pusher 6 and the first connecting member 7 contact, the rubber ring 181 and the rubber block 182 can buffer the impact force during contact, avoid direct contact between the first connecting member 7 and the second mounting plate 2 and cause damage, and play a protective role for the experimental device.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
