Description

Technical Field

[0001] This invention relates to the field of high-voltage switchgear testing, specifically to an intelligent testing device for high-voltage switchgear. Background Technology

[0002] High-voltage switchgear is an electrical device used in power systems for power generation, transmission, distribution, and energy conversion. It is used to open, close, control, and protect electrical equipment. Before leaving the factory, high-voltage switchgear needs to undergo intelligent testing, which includes tests on performance such as sealing and pressure resistance, to ensure the stable safety performance of the high-voltage switchgear.

[0003] Existing intelligent detection equipment for high-voltage switchgear includes, for example, a gas leak detection method and device for switchgear proposed in patent application number "CN202010006864.X". The leak detection method includes: filling a switchgear containing nitrogen with C4F7N gas; obtaining a first pressure inside the switchgear filled with C4F7N; determining whether a time interval is greater than a preset threshold; if so, obtaining a second pressure inside the switchgear; determining whether the first pressure is greater than the second pressure; if so, the switchgear is considered to be leaking; and using a C4F7N gas detector to determine the location of the leak. This gas leak detection method uses C4F7N gas as a tracer gas, determines whether the switchgear is leaking by pressure changes, and finally uses a C4F7N gas detector to determine the specific leak location. This method is unaffected by environmental interference and has high detection accuracy.

[0004] However, existing technologies have shortcomings. During use and transportation, high-voltage switchgear may encounter unexpected situations such as impacts, vibrations, and compression, which can affect the airtightness of the high-voltage switchgear. The existing switchgear testing methods have too limited environmental and functional scope and cannot simulate unexpected situations. Therefore, they cannot detect the airtightness of the high-voltage switchgear after encountering unexpected situations. Therefore, an intelligent testing device for high-voltage switchgear is proposed. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] A high-voltage switchgear intelligent testing device is disclosed. High-voltage switchgear belongs to the field of electrical equipment. The high-voltage switchgear intelligent testing device is used to intelligently test the airtightness of high-voltage switchgear. It belongs to the field of sealing monitoring technology and static or dynamic testing. It has the function of intelligently simulating the unexpected conditions of high-voltage switchgear being subjected to impact, vibration and compression.

[0038] A high-voltage switchgear intelligent testing device, such as Figures 1-7 As shown, it includes a base 1, a support base 3 is fixedly connected to the upper end of the base 1, a base 2 is fixedly connected to the back of the base 1, and a double clamping assembly is provided between the support base 3 and the base 1. The output end of the double clamping assembly is used to clamp and fix two sets of high voltage switch cabinets 7 to be tested at the same time.

[0039] The upper end of the base 2 is fixedly connected to an impact component for impacting the high voltage switchgear 7 under test. The top of the inner wall of the base 1 is fixedly connected to a vibration component for causing the base 1 to vibrate. The vibration component is driven and cooperates with the double clamping component. A unidirectional drive component is fixedly connected to the vibration component for making the double clamping component drive the vibration component to operate in a unidirectional manner.

[0040] Sufficient nitrogen-containing gas is injected into the high-voltage switchgear 7 to be tested. The pressure inside the high-voltage switchgear is measured using a gas pressure testing instrument. The high-voltage switchgear 7 filled with nitrogen-containing gas is placed on the upper end of the support base 3. Two sets of high-voltage switchgear can be placed on the upper end of the support base 3 at the same time, so that the equipment can test two sets of high-voltage switchgear at the same time, which improves the testing efficiency and reduces the testing error.

[0041] The dual clamping assembly can simultaneously clamp two sets of high-voltage switchgear 7 under test, control the operation of the dual clamping assembly and the impact assembly, and drive the vibration assembly to operate. The unidirectional drive assembly ensures that the vibration assembly does not operate during the clamping process of the high-voltage switchgear 7 under test, and is driven to operate during the release process.

[0042] When the dual-clamping assembly clamps the high-voltage switchgear 7 under test, the vibration assembly does not operate, and the impact assembly does not activate, simulating the clamping and squeezing conditions experienced by the high-voltage switchgear during handling or transportation. When the dual-clamping assembly clamps the high-voltage switchgear 7 under test, the vibration assembly does not operate, but the impact assembly activates, simulating the impact conditions experienced by the high-voltage switchgear during handling or transportation. When the dual-clamping assembly releases its grip on the high-voltage switchgear 7 under test, the vibration assembly is activated, but the impact assembly does not activate. The vibration assembly vibrates the base 1 during the release of the dual-clamping assembly, thereby causing the high-voltage switchgear to vibrate, simulating the vibration conditions experienced by the high-voltage switchgear. The cooperation between multiple components can intelligently simulate unexpected situations of impact, vibration, and squeezing encountered by the high-voltage switchgear. By comparing the gas pressure inside the high-voltage switchgear before and after the test, the airtightness of the high-voltage switchgear after encountering unexpected situations can be detected, providing a better assessment of the airtightness quality of the high-voltage switchgear and making the testing environment and functions more comprehensive.

[0043] like Figure 1 , Figure 3 , Figure 4 As shown, the dual clamping assembly includes two sets of symmetrically arranged clamping mechanisms and a central drive mechanism. Each clamping structure includes a set of vertical clamping plates 332 and two sets of horizontal clamping plates 341. The vertical clamping plates 332 are located between the two sets of horizontal clamping plates 341. The bottom of the support base 3 is fixedly connected to a horizontal slide rail 33 and a vertical slide rail 34. One end of the vertical clamping plate 332 is fixedly connected to a horizontal slider 331. The horizontal slider 331 is slidably connected to the horizontal slide rail 33, and the horizontal clamping plates 341 are slidably connected to the vertical slide rail 34.

[0044] Two sets of connecting arms 334 are rotatably mounted on the transverse slider 331. The ends of the two sets of connecting arms 334 are rotatably mounted to the two sets of horizontal clamping plates 341, respectively, so as to drive the two sets of horizontal clamping plates 341 to slide.

[0045] The central drive mechanism drives two sets of clamping mechanisms to operate. One set of vertical clamping plates 332 and two sets of horizontal clamping plates 341 clamp and squeeze the high-voltage switchgear on three sides. The horizontal slide rail 33 and the vertical slide rail 34 respectively restrict the movement trajectory of the vertical clamping plate 332 and the horizontal clamping plate 341. When the horizontal slider 331 slides, the horizontal slider 331 slides through the two sets of connecting arms 334 to push and pull the two sets of horizontal clamping plates 341.

[0046] like Figure 1 , Figure 3 , Figure 4 As shown, a central slide rail 36 is fixedly connected to the bottom of the support base 3. The central slide rail 36 is located between two sets of clamping mechanisms. Two sets of central clamping plates 361 are symmetrically slidably connected on the central slide rail 36. A rectangular opening 32 is opened in the middle of the support base 3. One end of each of the two sets of central clamping plates 361 passes through the rectangular opening 32, and the two sets of central clamping plates 361 are respectively clamped and cooperated with the two sets of clamping mechanisms.

[0047] A central clamping plate 361, a vertical clamping plate 332, and two horizontal clamping plates 341 clamp the high-voltage switchgear from all four sides.

[0048] like Figure 1 , Figure 3 , Figure 4 As shown, the central drive mechanism includes a push-pull cylinder 11, which is fixedly connected to the side wall of the base 1. A push-pull rod 111 is fixedly connected to the output end of the push-pull cylinder 11. The push-pull rod 111 slides between the support base 3 and the upper end of the base 1. A T-shaped seat 112 is fixedly connected to one end of the push-pull rod 111.

[0049] Two sets of connecting arms 114 are rotatably mounted on the T-shaped seat 112. The two sets of connecting arms 114 are symmetrically arranged, and the ends of the two sets of connecting arms 114 are rotatably connected to the two sets of central clamping plates 361, respectively, so as to drive the T-shaped seat 112 to slide the two sets of central clamping plates 361.

[0050] The output end of the push-pull cylinder 11 (model TN10-30) pushes or pulls the T-shaped seat 112 through the push-pull rod 111, so that the T-shaped seat 112 slides between the support seat 3 and the machine base 1. The T-shaped seat 112 pushes and pulls the two sets of central clamping plates 361 through the two sets of connecting arms 114, thereby driving the central clamping plates 361 to slide within the rectangular opening 32.

[0051] like Figure 1 , Figure 3 , Figure 4 As shown, rollers 113 are rotatably mounted on both sides of the T-shaped seat 112, and right-angled trapezoidal side seats 333 are fixedly connected to the sides of the two sets of transverse sliders 331. The two sets of rollers 113 are respectively pressed and engaged with the inclined surfaces of the two sets of right-angled trapezoidal side seats 333.

[0052] A vertical plate 35 is fixedly connected to the bottom of the support base 3. A rod 351 is fixedly connected to one side of the vertical plate 35. The end of the rod 351 is inserted into the right-angled trapezoidal side seat 333. A reset spring 352 is sleeved on the side wall of the rod 351. One end of the reset spring 352 is fixedly connected to the vertical plate 35, and the other end is fixedly connected to the right-angled trapezoidal side seat 333. The reset spring 352 is used to drive the horizontal slider 331 to reset and slide.

[0053] When the T-shaped base 112 slides inward toward the support base 3, the T-shaped base 112 pulls the two sets of central clamping plates 361 closer together via the two sets of connecting arms 114. The central clamping plates 361 move away from the high-voltage switchgear, and the roller 113 presses against the right-angled trapezoidal side seat 333, pushing the horizontal slider 331 to slide. The compression degree of the return spring 352 increases, and both the vertical clamping plate 332 and the horizontal clamping plate 341 move away from the high-voltage switchgear. At this time, the high-voltage switchgear is released from clamping and squeezing. When the T-shaped base 112 slides outward toward the support base 3, the T-shaped base 112 pushes the two sets of central clamping plates 361 away from the support base 3 via the two sets of connecting arms 114. The central clamping plates 361 move closer to squeezing the high-voltage switchgear, and the roller 113 gradually loosens the compression degree on the right-angled trapezoidal side seat 333. The return spring 352 gradually recovers its deformation and pushes the horizontal slider 331 to slide through the right-angled trapezoidal side seat 333, so that both the vertical clamping plate 332 and the horizontal clamping plate 341 move closer to squeezing the high-voltage switchgear. At this time, the high-voltage switchgear is clamped and squeezed.

[0054] like Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the vibration assembly includes a support frame 12, which is fixed to the top of the inner wall of the base 1. A first shaft 13 and a second shaft 14 are rotatably mounted on the support frame 12. The second shaft 14 is located below the first shaft 13. A drive gear 132 is fixedly connected to the middle of the first shaft 13, and amplifying gears 131 are fixedly connected to both ends. A corrugated rod 115 is fixedly connected to the output end of the push-pull cylinder 11. The corrugated rod 115 is inserted into the side wall of the base 1, and the drive gear 132 meshes with the corrugated rod 115 for transmission.

[0055] When the output end of the push-pull cylinder 11 drives the push-pull rod 111 to run, it simultaneously drives the bellows rod 115 to pass through the base 1. The cross-sectional shape of each set of bellows rod 115 is set as an isosceles trapezoid to facilitate meshing transmission. The operation of the bellows will mesh with the drive gear 132, causing the shaft 13 to rotate, thereby causing the two sets of amplifying gears 131 to rotate. The diameter of the amplifying gear 131 is many times larger than that of the drive gear 132. The rotation angles of the drive gear 132 and the amplifying gear 131 are the same, but the rotation path of the amplifying gear 131 is larger than that of the drive gear 132, thus amplifying the path.

[0056] like Figure 3 , Figure 5 , Figure 6 , Figure 7As shown, both ends of the shaft 14 are fixedly connected to turntables 141. Multiple sets of striking plates 142 are rotatably installed on both sets of turntables 141. The striking plates 142 are used to strike the base 1 to induce vibration. Two sets of unidirectional drive components are provided. Both sets of unidirectional drive components are fixedly connected to the shaft 14, and the two sets of unidirectional drive components are respectively meshed with two sets of amplifying gears 131 for transmission.

[0057] Two sets of amplifying gears 131 drive two sets of unidirectional drive components to rotate. The diameter of the amplifying gear 131 is many times the outer diameter of the unidirectional drive component. When the two mesh, the rotation angle of the unidirectional drive component is many times the rotation angle of the amplifying gear 131. As a result, when the bellows rod 115 moves a small path, the rotating shaft 2 can rotate multiple times, the turntable 141 can rotate multiple times, and the striking plate 142 can strike the base 1 multiple times, causing the base 1 to vibrate continuously.

[0058] like Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the unidirectional drive assembly includes a disk 15, which is fixedly connected to a shaft 14. The disk 15 and the shaft 14 are coaxial. A toothed ring 151 is rotatably mounted on the outer wall of the disk 15. The toothed ring 151 meshes with an amplifying gear 131 for transmission. A toothed ring 152 is fixedly connected to the inner wall of the toothed ring 151 at a position on one side of the disk 15.

[0059] A sliding frame 153 is fixedly connected to the disk 15, and a right-angled trapezoidal elastic block 154 is slidably connected inside the sliding frame 153. The teeth of the toothed ring 152 are set to be right-angled trapezoidal. The inclined surface of the teeth of the toothed ring 152 is pressed and engaged with the inclined surface of the right-angled trapezoidal elastic block 154, and the vertical surface of the teeth of the toothed ring 152 is pressed and engaged with the vertical surface of the right-angled trapezoidal elastic block 154.

[0060] The rotation of the amplifying gear 131 will definitely cause the toothed ring 151 to rotate, but not necessarily the disc 15. When the output end of the push-pull cylinder 11 extends, the double clamping assembly disengages from the clamping and squeezing of the high-voltage switchgear, driving the gear 132 to rotate clockwise, the amplifying gear 131 to rotate clockwise, and the toothed ring 151 to rotate counterclockwise. The inclined surface of the toothed ring 152 presses against the inclined surface of the right-angled trapezoidal elastic block 154. The right-angled trapezoidal elastic block 154 (composed of a right-angled trapezoidal block and a spring, with the spring fixedly connected to the inside of the slide frame 153 and the right-angled trapezoidal block slidingly connected within the slide frame 153) is subjected to... When the cylinder is pressed into the sliding frame 153, it cannot cause the disc 15 to rotate. When the output end of the push-pull cylinder 11 retracts, the double clamping assembly clamps and squeezes the high-voltage switchgear, driving the gear 132 to rotate counterclockwise, the amplifying gear 131 to rotate counterclockwise, and the toothed ring 151 to rotate clockwise. The vertical surface of the toothed ring 152 and the vertical surface of the right-angled trapezoidal elastic block 154 are pressed together, driving the disc 15 to rotate, thereby driving the rotating shaft 2 to rotate. Therefore, the double clamping assembly only causes the vibration assembly to operate when the clamping is released, avoiding the vibration assembly from affecting the clamping of the high-voltage switchgear and simulating the actual situation.

[0061] like Figure 1 , Figure 2 As shown, the impact assembly includes a bracket 4, which is fixed to the upper end of the base 2. A lifting cylinder 41 is fixed to the upper end of the bracket 4. The output end of the lifting cylinder 41 faces downward and is fixed to a lifting seat 5. Two sets of fixed seats 6 are fixed to the lower end of the lifting seat 5. Each set of fixed seats 6 is rotatably connected to a gear plate 61, a transmission gear 62 and a rotating rod 63 at the lower end.

[0062] The first transmission gear 62 is located between the gear disk 61 and the rotating rod 63. The first transmission gear 62 meshes with the gear disk 61 for transmission. The second transmission gear 631 is fixedly connected to the side wall of the rotating rod 63. The second transmission gear 631 meshes with the first transmission gear 62 for transmission. The top impact hammer 611 for impacting the top of the high-voltage switchgear 7 under test is fixedly connected to the side wall of the gear disk 61. The side impact hammer 632 for impacting the side of the high-voltage switchgear 7 under test is fixedly connected to the lower end of the rotating rod 63.

[0063] The lifting cylinder 41 (model TN16X20S) drives the lifting seat 5 to rise and fall. The gear plate 61 rotates, which drives the transmission gear 62 to rotate. The transmission gear 62 drives the rotating rod 63 to rotate through the transmission gear 631, so that the top impact hammer 611 and the side impact hammer 632 impact the top and side of the high-voltage switchgear respectively. The impact area is more comprehensive, which can detect the airtightness of the high-voltage switchgear after being impacted.

[0064] like Figure 1 , Figure 2As shown, a servo motor 51 is fixedly connected to the lower end of the lifting seat 5, and a power gear 511 is fixedly connected to the output end of the servo motor 51. A connecting rod 64 is fixedly connected between the two sets of gear discs 61, and a power gear 641 is fixedly connected to the side wall of the connecting rod 64. The connecting rod 64, the power gear 511 and the gear discs 61 are coaxial, and the power gear 641 meshes with the power gear 511 for transmission.

[0065] Servo motor 51 (model 110ST-M05030) drives power gear 511 to reciprocate at a certain angle, which causes power gear 641 to drive connecting rod 64 to rotate at a certain angle. The outer diameter of the teeth of power gear 511, power gear 641, gear plate 61, transmission gear 62 and transmission gear 631 are the same, so they all rotate at the same angle to avoid structural jamming and inability to operate due to different angles. This allows the top impact hammer 611 and the side impact hammer 632 to strike the high-voltage switchgear synchronously.

[0066] The working principle of the intelligent testing device for high-voltage switchgear provided by this invention is as follows:

[0067] Sufficient nitrogen-containing gas is injected into the high-voltage switchgear 7 under test. The pressure inside the switchgear is measured using a gas pressure testing instrument. The high-voltage switchgear 7 filled with nitrogen gas is placed on the upper end of the support base 3. When the double clamping assembly clamps the high-voltage switchgear 7 under test, the vibration assembly does not operate and the impact assembly does not activate due to the presence of the unidirectional drive assembly, which can simulate the clamping and squeezing conditions experienced by the high-voltage switchgear during handling or transportation. When the double clamping assembly clamps the high-voltage switchgear 7 under test, the vibration assembly does not operate and the impact assembly activates, which can simulate the impact conditions experienced by the high-voltage switchgear during handling or transportation. The system simulates an impact scenario: when the dual clamping assembly releases its grip on the high-voltage switchgear 7 under test, the vibration assembly is activated, while the impact assembly remains closed. The vibration assembly vibrates the base 1 during the release of the dual clamping assembly, causing the high-voltage switchgear to vibrate and simulating the vibration of the high-voltage switchgear. The coordinated operation of multiple components intelligently simulates unexpected impacts, vibrations, and compressions to the high-voltage switchgear. By comparing the internal gas pressure of the high-voltage switchgear before and after testing, the system can assess the airtightness of the high-voltage switchgear after such incidents, providing a more comprehensive assessment of its airtightness and functionality.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
