[0001] The utility model relates to the technical field of lightning impulse test equipment, in particular to a lightning impulse high-voltage generator. Background Art

[0002] The lightning impulse high voltage generator is a test equipment specially used to simulate the natural lightning impulse effect. It can quickly generate high voltage, short pulse lightning waveforms, accurately simulate the impact of lightning on power equipment and systems. The impulse voltage generator console is the core component of the power test equipment. It integrates precise control systems and monitoring technologies to accurately control and generate high voltage, short pulse impulse waveforms to meet the needs of power equipment insulation strength testing. The console is easy to operate and has a user-friendly interface. It can adjust the voltage amplitude, waveform parameters and duration in real time to ensure the accuracy and repeatability of the test results. At the same time, it also has a complete protection mechanism to ensure safe operation. It is an indispensable and important tool in power research, production and quality inspection.

[0003] In order to facilitate moving to different places for use, the existing impulse voltage generator console is usually equipped with a plurality of universal wheels with a self-locking function at the bottom. After moving to a designated location, the universal wheels are locked with a locking mechanism on the universal wheels. Since the impulse voltage generator console itself is heavy, the locking mechanism is prone to loosening or even damage after long-term use, causing the wheels to shift and slide, affecting the placement stability and use. At the same time, when the existing impulse voltage generator console is unlocked, the universal wheels below are subjected to a large gravity, resulting in a laborious and inconvenient operation when the lock of the universal wheels needs to be unlocked.

[0004] Therefore, it is necessary to provide a lightning impulse high voltage generator to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a lightning impulse high voltage generator to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model solves the above-mentioned technical problems as follows: a lightning impulse high-voltage generator, including an impulse voltage generator console, a base is fixed at the bottom of the impulse voltage generator console, an inner cavity is opened inside the base, a partition is fixed inside the base and the inner cavity of the base is divided into two cavities by the partition, and a rolling component that can switch the impulse voltage generator console to be stably placed and conveniently moved is arranged in the two cavities, and a pushing component connected to the interior of the cavity is arranged on the outside of the base.

[0007] As a further solution of the utility model, the rolling component includes an internal cylinder fixed on the inner side wall of the bottom end of the cavity and communicated with the cavity. There are multiple internal cylinders, and the multiple internal cylinders are equidistantly distributed. A sliding column is slidably connected in the internal cylinder. The top end of the sliding column is fixed with a first piston plate tightly fitted with the inner side wall of the internal cylinder, and the bottom end of the sliding column is rotatably connected with a ball.

[0008] As a further solution of the utility model, the pushing component includes a U-shaped pipe fixed at one end of the base.

The external liquid cylinder is communicated with the U-shaped pipe. An electric telescopic rod is arranged on one side of the external liquid cylinder. The output rod of the electric telescopic rod is inserted into the internal part of the external liquid cylinder, and a second piston plate tightly fitted with the inner side wall of the external liquid cylinder is fixed on the end of the output rod of the electric telescopic rod.

[0009] As a further solution of the utility model, valves are installed on both sections of the U-shaped pipe to control the opening and closing of the liquid inlet of the cavity.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The liquid is squeezed into the inside of the base and introduced into the cavity through the pushing component, so that a certain hydraulic pressure is formed inside the cavity. Then, the rolling component is pushed by the hydraulic pressure to extend from the bottom of the base and roll into contact with the ground, so that the bottom surface of the base is lifted off the ground and suspended. Furthermore, it is convenient to push and move the impact voltage generator console. When it is necessary to place the impact voltage generator console, the hydraulic pressure inside the cavity of the base is released through the pushing component, so as to relieve the pressure on the rolling component. Thus, the rolling component can be retracted into the inside of the base, so that the bottom surface of the base contacts the ground, and the stable placement of the impact voltage generator console can be realized. The stability of the placement of the impact voltage generator console is effectively improved, and the problem that the universal wheels are easily damaged due to long-term pressure is avoided. The convenient switching between the stable placement and the movement of the impact voltage generator console is realized, and the operation is convenient.

[0014] 2. When placing the impulse voltage generator console on an inclined ground with a certain inclination, the liquid can be controlled to be conveyed into one of the cavities through the pushing component to make it have hydraulic pressure, so as to control the rolling component in a single cavity to extend to a certain extent, thereby adjusting the inclination of the base, and further adjusting the placement inclination of the impulse voltage generator console, so that the impulse voltage generator console is horizontally placed on the inclined ground, ensuring that the impulse voltage generator console can always be horizontally placed, facilitating use, and effectively improving the overall practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present utility model will be further described below in conjunction with the embodiments.

[0026] Please refer to Figures 1-7, the present utility model provides a lightning impulse high-voltage generator, which includes an impulse voltage generator control console 4. A base 3 is fixed at the bottom of the impulse voltage generator control console 4. An inner cavity is provided inside the base 3. A partition 7 is fixed inside the base 3, and the inner cavity inside the base 3 is divided into two cavities 6 by the partition 7. Rolling components 1 for switching between stably placing and conveniently moving the impulse voltage generator control console 4 are arranged in both cavities 6. A pressing component 2 communicated with the inside of the cavity 6 is arranged outside the base 3. When transferring the impulse voltage generator control console 4, the liquid is squeezed into the inside of the base 3 through the pressing component 2 and introduced into the cavity 6, so that a certain hydraulic pressure is formed inside the cavity 6. Thus, the rolling components 1 are pressed by the hydraulic pressure to extend from the bottom of the base 3 and roll into contact with the ground, so that the bottom surface of the base 3 is lifted off the ground and suspended, and then it is convenient to push the impulse voltage generator control console 4 for moving and transferring. When it is necessary to place the impulse voltage generator control console 4, the hydraulic pressure inside the cavity 6 of the base 3 is released through the pressing component 2, so as to relieve the pressure on the rolling components 1, so that the rolling components 1 can be retracted into the inside of the base 3, so that the bottom surface of the base 3 contacts the ground, and thus the stable placement of the impulse voltage generator control console 4 can be realized, effectively improving the placement stability of the impulse voltage generator control console 4, avoiding the problem that the universal wheels are easily damaged due to long-term pressure, and realizing the convenient switching between the stable placement and the movement of the impulse voltage generator control console 4, with convenient operation. When the impulse voltage generator control console 4 is placed on an inclined ground with a certain inclination, the pressing component 2 can be used to control the liquid to be conveyed into one of the cavities 6 to make it have hydraulic pressure, so as to control the rolling components 1 in a single cavity 6 to extend to a certain extent, so as to adjust the inclination of the base 3, and then adjust the placement inclination of the impulse voltage generator control console 4, so that the impulse voltage generator control console 4 is horizontally placed on the inclined ground, ensuring that the impulse voltage generator control console 4 can always be horizontally placed, facilitating use, and effectively improving the overall practicality.

[0027] Further, as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth specifically explaining that the rolling component 1 includes an inner cylinder 101 fixed to the inner side wall of the bottom end of the cavity 6 and communicating with the cavity 6. There are multiple inner cylinders 101, and the multiple inner cylinders 101 are equally spaced. A sliding column 102 is slidably connected inside the inner cylinder 101. The top end of the sliding column 102 is fixed with a first piston plate 103 that closely fits with the inner side wall of the inner cylinder 101. The bottom end of the sliding column 102 is rotatably connected with a ball 104. When transferring the impulse voltage generator console 4, the liquid is squeezed into the inside of the base 3 through the pushing component 2 and introduced into the cavity 6, so that a certain hydraulic pressure is formed inside the cavity 6. Thus, the multiple first piston plates 103 are synchronously pressed to move downward inside the inner cylinder 101 by the hydraulic pressure, thereby pushing the multiple sliding columns 102 to extend downward from the inner cylinder 101, so that the multiple balls 104 are in rolling contact with the ground, thereby lifting the bottom surface of the base 3 off the ground and suspending it. Furthermore, it is convenient to push the impulse voltage generator console 4 for movement and transfer. When it is necessary to place the impulse voltage generator console 4, the hydraulic pressure inside the cavity 6 of the base 3 is released through the pushing component 2, thereby relieving the pressure on the first piston plate 103, so that the sliding column 102 and the ball 104 can be retracted into the inner cylinder 101, so that the bottom surface of the base 3 contacts the ground, so that the stable placement of the impulse voltage generator console 4 can be realized, effectively improving the placement stability of the impulse voltage generator console 4, avoiding the problem that the universal wheels are easily damaged due to long-term pressure, realizing the convenient switching between the stable placement and the movement of the impulse voltage generator console 4, and the operation is convenient.

[0028] Further, as Figure 1 、 Figure 3 、 Figure 6 and Figure 7As shown, it is worth specifically explaining that the pressing component 2 includes a U-shaped tube 201 fixed at one end of the base 3. Both ends of the U-shaped tube 201 are respectively communicated with two cavities 6. An external liquid cylinder 203 is fixed on the outer side wall of the U-shaped tube 201. The external liquid cylinder 203 is communicated with the U-shaped tube 201. An electric telescopic rod 204 is arranged on one side of the external liquid cylinder 203. The output rod of the electric telescopic rod 204 is inserted into the internal part of the external liquid cylinder 203 and a second piston plate 205 tightly fitted with the inner side wall of the external liquid cylinder 203 is fixed on the end of the output rod of the electric telescopic rod 204. Valves 202 are installed on both sections of the U-shaped tube 201 to control the liquid inlet of the cavity 6 by the valves 202; A certain amount of liquid is filled in both the internal part of the external liquid cylinder 203 and the cavity 6. The liquid can be water or hydraulic oil, etc. During specific operation, the output rod of the electric telescopic rod 204 drives the second piston plate 205 to press down in the external liquid cylinder 203, so as to synchronously squeeze the liquid in the external liquid cylinder 203 into the two cavities 6 through the second piston plate 205, so that a certain hydraulic pressure is generated in the two cavities 6, thereby pressing the ball 104 to contact the ground and realizing the convenient movement of the impulse voltage generator console 4. When the impulse voltage generator console 4 is placed on an inclined ground with a certain inclination, one of the valves 202 can be closed to make the liquid in the external liquid cylinder 203 concentratedly input into one of the cavities 6 to generate hydraulic pressure, so as to control the sliding column 102 in the single cavity 6 to extend out of the built-in cylinder 101 to a certain extent, thereby adjusting the inclination of the base 3, and further adjusting the placement inclination of the impulse voltage generator console 4, so that the impulse voltage generator console 4 is horizontally placed on the inclined ground, ensuring that the impulse voltage generator console 4 can always be horizontally placed, facilitating use and effectively improving the overall practicability.

[0029] This solution has the following working process: When operating the transfer impulse voltage generator console 4, the output rod of the electric telescopic rod 204 drives the second piston plate 205 to press down in the external liquid cylinder 203, thereby synchronously squeezing the liquid in the external liquid cylinder 203 into the two cavities 6 through the second piston plate 205, so that there is a certain hydraulic pressure in the two cavities 6. Then, the hydraulic pressure synchronously presses multiple first piston plates 103 to move downward in the built-in cylinder 101, thus pushing multiple sliding columns 102 to move downward and extend out of the built-in cylinder 101, making multiple balls 104 roll into contact with the ground, thereby lifting the bottom surface of the base 3 off the ground and suspending it. This facilitates the pushing and moving of the impulse voltage generator console 4. When it is necessary to place the impulse voltage generator console 4, by releasing the hydraulic pressure inside the cavity 6 of the base 3, the pressure on the first piston plate 103 is released, so that the sliding columns 102 and the balls 104 can retract into the built-in cylinder 101, making the bottom surface of the base 3 contact the ground, thus realizing the stable placement of the impulse voltage generator console 4. When placing the impulse voltage generator console 4 on an inclined ground with a certain inclination, one of the valves 202 can be closed to make the liquid in the external liquid cylinder 203 concentrate and input into one of the cavities 6, making it have hydraulic pressure, thereby controlling the sliding column 102 in a single cavity 6 to extend out of the built-in cylinder 101 to a certain extent, so as to adjust the inclination of the base 3, and further adjust the placement inclination of the impulse voltage generator console 4, making the impulse voltage generator console 4 horizontally placed on the inclined ground.

[0030] Furthermore, as Figure 5 shown, it is specifically noted that an inclined surface 106 is provided at the bottom end of the sliding column 102. During specific operation, the inclined surface 106 is provided to increase the gap between the bottom of the sliding column 102 and the ground, improving the stability of the impulse voltage generator console 4 during movement.

[0031] Furthermore, as Figure 1 and Figure 2 shown, it is specifically noted that a support plate 5 is fixed on the outer plate of the impulse voltage generator console 4, and the electric telescopic rod 204 is fixed on the side surface of the support plate 5.

[0032] In summary: The liquid is squeezed into the interior of the base 3 through the pressing component 2 and introduced into the interior of the cavity 6, so that a certain hydraulic pressure is formed inside the cavity 6. Thus, the rolling component 1 is pushed out from the bottom of the base 3 by the hydraulic pressure and makes rolling contact with the ground, so that the bottom surface of the base 3 is lifted off the ground and suspended. Furthermore, it is convenient to push and move the impulse voltage generator console 4. When it is necessary to place the impulse voltage generator console 4, the hydraulic pressure inside the cavity 6 of the base 3 is released through the pressing component 2, so as to relieve the pressure on the rolling component 1. Thus, the rolling component 1 can retract into the interior of the base 3, so that the bottom surface of the base 3 contacts the ground, and thus the stable placement of the impulse voltage generator console 4 can be realized. The placement stability of the impulse voltage generator console 4 is effectively improved, and the problem that the universal wheels are easily damaged due to long-term pressure is avoided. The convenient switching between the stable placement and the movement of the impulse voltage generator console 4 is realized, and the operation is convenient. When the impulse voltage generator console 4 is placed on an inclined ground with a certain inclination, the liquid can be conveyed into one of the cavities 6 through the pressing component 2 to make it have hydraulic pressure, so as to control the rolling component 1 in the single cavity 6 to extend to a certain extent. Thus, the inclination of the base 3 can be adjusted, and further the placement inclination of the impulse voltage generator console 4 can be adjusted, so that the impulse voltage generator console 4 is horizontally placed on the inclined ground, ensuring that the impulse voltage generator console 4 can always be horizontally placed, which is convenient for use and effectively improves the overall practicability.

[0033] The electric telescopic rod 204 can be purchased on the market. The electric telescopic rod 204 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed. Therefore, it will not be repeated in the specification.
