Description

Technical Field

[0001] The present invention relates to the field of high-voltage switchgear detection, and specifically to an intelligent detection device for high-voltage switchgear. Background Technique

[0002] A high-voltage switchgear is an electrical device that, during the processes of power generation, transmission, distribution, and power conversion in the power system, switches, controls, and protects electrical equipment. Before leaving the factory, high-voltage switchgear needs to undergo intelligent detection, and the detection items include performance such as airtightness and compressive resistance to ensure the stable safety performance of the high-voltage switchgear.

[0003] Existing intelligent detection devices for high-voltage switchgear, such as a gas leak detection method and device for a switchgear proposed in the patent application number "CN202010006864.X", the leak detection method includes: filling C4F7N gas into a switchgear containing nitrogen; obtaining the first pressure inside the switchgear filled with C4F7N; determining whether the time interval is greater than a preset threshold, if so, obtaining the second pressure inside the switchgear; determining whether the first pressure is greater than the second pressure, if so, the switchgear leaks air; using a C4F7N gas detector to determine the location where the switchgear leaks air. The aforementioned gas leak detection method uses C4F7N gas as a tracer gas, judges whether the switchgear leaks air through the change in pressure, and finally uses a C4F7N gas detector to determine the specific leak location. Using the aforementioned leak detection method, it is not affected by the environment and has high detection accuracy.

[0004] However, there are defects in the existing technology. During the use and transportation of high-voltage switchgear, it may encounter accidental conditions such as impact, vibration, and extrusion, which can all affect the airtightness of the high-voltage switchgear. The environment and functions of the existing detection methods for switchgear are too single and cannot simulate accidental conditions. Therefore, it is impossible to detect the airtightness of high-voltage switchgear after encountering accidental conditions. Therefore, an intelligent detection device for high-voltage switchgear is proposed. Summary of the Invention

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] An intelligent detection device for high-voltage switchgear belongs to the field of electrical equipment. The intelligent detection device for high-voltage switchgear is a device used to intelligently detect the airtightness of high-voltage switchgear, which belongs to one of the sealing monitoring technologies, static or dynamic detections, and has the function of intelligently simulating accidental situations such as impacts, vibrations, and squeezes encountered by high-voltage switchgear.

[0038] An intelligent detection device for high-voltage switchgear, as [[ID=…]] Figures 1-7 shown, includes a machine base 1. A support seat 3 is fixedly connected to the upper end of the machine base 1, a base 2 is fixedly connected to the back of the machine base 1, and a double clamping assembly is provided between the support seat 3 and the machine base 1. The output end of the double clamping assembly is used to clamp and fix two groups of high-voltage switchgears 7 under test at the same time;

[0039] An impact assembly for impacting the high-voltage switchgear 7 under test is fixedly connected to the upper end of the base 2, a vibration assembly for causing the machine base 1 to vibrate is fixedly connected to the inner wall top of the machine base 1. The vibration assembly is drivingly matched with the double clamping assembly, and a one-way driving assembly is fixedly connected to the vibration assembly for enabling the double clamping assembly to drive the vibration assembly to operate unidirectionally.

[0040] A sufficient amount of nitrogen-containing gas is injected into the high-voltage switch cabinet 7 to be tested, and a gas pressure detection instrument is used to detect the pressure in the high-voltage switch cabinet at this time. The high-voltage switch cabinet 7 to be tested filled with nitrogen-containing gas is placed on the upper end of the support base 3. Two groups of high-voltage switch cabinets can be placed on the upper end of the support base 3 at the same time, so that the device can detect two groups of high-voltage switch cabinets at the same time, thereby improving the detection efficiency and reducing the detection error.

[0041] The double clamping assembly can synchronously clamp two groups of high-voltage switch cabinets 7 to be tested, control the operation of the double clamping assembly and the impact assembly, and the double clamping assembly can drive the vibration assembly to operate. The unidirectional drive assembly makes the vibration assembly not operate during the clamping process of the high-voltage switch cabinet 7 to be tested, and the vibration assembly is driven to operate during the release process.

[0042] When the double clamping assembly clamps the high-voltage switchgear 7 to be tested, the vibration assembly does not operate and the impact assembly is not turned on, which can simulate the clamping and squeezing conditions encountered by the high-voltage switchgear during handling or transportation; when the double clamping assembly clamps the high-voltage switchgear 7 to be tested, the vibration assembly does not operate and the impact assembly is turned on, which can simulate the conditions of the high-voltage switchgear being hit during handling or transportation; when the double clamping assembly releases the clamping of the high-voltage switchgear 7 to be tested, the vibration assembly is driven to operate and the impact assembly is not turned on. The vibration assembly vibrates the base 1 during the release of the double clamping assembly, thereby causing the high-voltage switchgear to vibrate, simulating the conditions of the high-voltage switchgear being vibrated; the cooperation between multiple components can intelligently simulate the accidental conditions of the high-voltage switchgear encountering impact, vibration and extrusion, and compare the gas pressure inside the high-voltage switchgear before and after the test, so as to detect the airtightness of the high-voltage switchgear after encountering the accident, and better judge the airtightness quality of the high-voltage switchgear, and the detection environment and functions are more comprehensive.

[0043] like Figure 1 、 Figure 3 、 Figure 4 As shown, the double clamping assembly includes two sets of symmetrically arranged clamping mechanisms and a set of central driving mechanisms. Each set of clamping structures 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 the horizontal slide rail 33 and the vertical slide rail 34. One end of the vertical clamping plate 332 is fixedly connected to the horizontal slider 331. The horizontal slider 331 is slidably connected to the horizontal slide rail 33, and the horizontal clamping plate 341 is 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 on the two sets of transverse clamping plates 341 , so that the transverse slider 331 drives the two sets of transverse clamping plates 341 to slide.

[0045] The central drive mechanism drives the operation of two sets of clamping mechanisms. A set of vertical clamping plates 332 and two sets of horizontal clamping plates 341 clamp and squeeze three sides of the high-voltage switchgear. The horizontal slide rail 33 and the vertical slide rail 34 respectively limit the movement trajectories of the vertical clamping plate 332 and the horizontal clamping plate 341. When the horizontal slider 331 slides the rod, the horizontal slider 331 pushes and pulls the two sets of horizontal clamping plates 341 to slide through two sets of connecting arms II 334.

[0046] As 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 the two sets of clamping mechanisms. Two sets of central clamping plates 361 are symmetrically and slidably connected to the central slide rail 36. A rectangular opening 32 is formed in the middle of the support base 3. One ends of the two sets of central clamping plates 361 both penetrate through the rectangular opening 32, and the two sets of central clamping plates 361 are respectively in clamping cooperation with the two sets of clamping mechanisms.

[0047] One set of central clamping plates 361, one set of vertical clamping plates 332 and two sets of horizontal clamping plates 341 squeeze and clamp the four sides of the high-voltage switchgear.

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

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

[0050] The output end of the push-pull cylinder 11 (model number 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 base 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 I 114, thereby driving the central clamping plates 361 to slide in the rectangular opening 32.

[0051] As Figure 1 , Figure 3 , Figure 4 As shown, rollers 113 are rotatably installed on both sides of the T-shaped seat 112. Right-angled trapezoidal side seats 333 are fixedly connected to the sides of the two sets of horizontal sliders 331. The two sets of rollers 113 are respectively in extrusion cooperation 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. An insertion rod 351 is fixedly connected to one side of the vertical plate 35. The end of the insertion rod 351 is inserted and installed in a right-angled trapezoidal side seat 333. A return spring 352 is sleeved on the side wall of the insertion rod 351. One end of the return 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 return spring 352 is used to drive the lateral slider 331 to slide back to its original position.

[0053] When the T-shaped seat 112 slides into the support base 3, the T-shaped seat 112 pulls two central clamping plates 361 closer through two sets of first connecting arms 114. The central clamping plates 361 move away from the high-voltage switchgear. The roller 113 presses against the right-angled trapezoidal side seat 333, pushing the lateral slider 331 to slide, and the degree of compression of the return spring 352 increases. 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 disengaged from the clamping and extrusion. When the T-shaped seat 112 slides out of the support base 3, the T-shaped seat 112 pushes two central clamping plates 361 away through two sets of first connecting arms 114. The central clamping plates 361 move closer to and squeeze the high-voltage switchgear. The roller 113 gradually releases the degree of extrusion on the right-angled trapezoidal side seat 333. The return spring 352 gradually recovers its deformation. Through the right-angled trapezoidal side seat 333, it drives the lateral slider 331 to slide, causing both the vertical clamping plate 332 and the horizontal clamping plate 341 to move closer to and squeeze the high-voltage switchgear. At this time, the high-voltage switchgear is clamped and extruded.

[0054] As Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 As shown in

[0055] When the output end of the push-pull cylinder 11 drives the push-pull rod 111 to operate, it simultaneously drives the corrugated rod 115 to penetrate through the machine base 1. The cross-sectional shape of each corrugation of the corrugated rod 115 is set as an isosceles trapezoid, which is convenient for meshing transmission. When the corrugated pipe operates, it will meshingly drive the driving gear 132, causing the shaft body 13 to rotate, and thus causing the two magnifying gears 131 to rotate. The diameter of the magnifying gear 131 is many times larger than that of the driving gear 132. The rotation angles of the driving gear 132 and the magnifying gear 131 are the same, but the rotation path of the magnifying gear 131 is greater than that of the driving gear 132, playing a role in magnifying the path.

[0056] As Figure 3 、 Figure 5 、 Figure 6 、 Figure 7As shown, turntables 141 are fixedly connected to both ends of the second shaft body 14. A plurality of percussion plates 142 are rotatably mounted on each of the two turntables 141. The percussion plates 142 are used to strike the machine base 1 to cause vibration. Two sets of one-way drive components are provided. The two sets of one-way drive components are fixedly connected to the second shaft body 14, and the two sets of one-way drive components are respectively meshed and driven with the two enlarged gears 131.

[0057] The two enlarged gears 131 drive the two sets of one-way drive components to rotate. The diameter of the enlarged gear 131 is multiple times that of the outer diameter of the one-way drive component. When the two are meshed and driven, the rotation angle of the one-way drive component is multiple times that of the enlarged gear 131. Thus, when the corrugated rod 115 moves a small path, the second rotating shaft can rotate multiple circles, the turntable 141 can rotate multiple circles, and the percussion plate 142 can strike the machine base 1 multiple times, causing persistent vibration of the machine base 1.

[0058] As Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the one-way drive component includes a disc 15. The disc 15 is fixedly connected to the second shaft body 14. The disc 15 is coaxial with the second shaft body 14. A toothed ring 151 is rotatably mounted on the outer wall of the disc 15. The toothed ring 151 is meshed and driven with the enlarged gear 131. A toothed circle 152 is fixedly connected to a position on the inner wall of the toothed ring 151 on one side of the disc 15;

[0059] A sliding frame 153 is fixedly connected to the disc 15. A right trapezoidal elastic clamping block 154 is slidably connected in the sliding frame 153. The tooth shape of the toothed circle 152 is set as a right trapezoid. The inclined surface of the tooth of the toothed circle 152 is in extrusion fit with the inclined surface of the right trapezoidal elastic clamping block 154, and the vertical surface of the tooth of the toothed circle 152 is in extrusion fit with the vertical surface of the right trapezoidal elastic clamping block 154.

[0060] The rotation of the magnifying gear 131 will definitely cause the rotation of the tooth ring 151, but not necessarily the rotation of 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, the driving gear 132 rotates clockwise, the magnifying gear 131 rotates clockwise, and the tooth ring 151 rotates counterclockwise. The inclined surface of the tooth of the tooth ring 152 is in extrusion fit with 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, the spring is fixedly connected to the inside of the sliding frame 153, and the right-angled trapezoidal block is slidably connected inside the sliding frame 153) is pressed into the sliding frame 153 and cannot cause the disc 15 to rotate. When the output end of the push-pull cylinder 11 contracts, the double clamping assembly clamps and squeezes the high-voltage switchgear, the driving gear 132 rotates counterclockwise, the magnifying gear 131 rotates counterclockwise, the tooth ring 151 rotates clockwise, the vertical surface of the tooth of the tooth ring 152 is in extrusion fit with the vertical surface of the right-angled trapezoidal elastic block 154, driving the disc 15 to rotate, thereby driving the second rotating shaft to rotate. Therefore, the double clamping assembly only causes the vibration assembly to operate when releasing the clamping, avoiding the influence of the vibration assembly on the clamping of the high-voltage switchgear and better simulating the actual situation.

[0061] As Figure 1 , Figure 2 shown, the impact assembly includes a bracket 4, the bracket 4 is fixedly connected to the upper end of the base 2, a lifting cylinder 41 is fixedly connected to the upper end of the bracket 4, the output end of the lifting cylinder 41 faces downward, and a lifting seat 5 is fixedly connected to the output end of the lifting cylinder 41. Two fixed seats 6 are fixedly connected to the lower end of the lifting seat 5. A tooth disc 61, a first transmission gear 62 and a rotating rod 63 are rotatably connected to the lower end of each fixed seat 6;

[0062] The first transmission gear 62 is located between the tooth disc 61 and the rotating rod 63. The first transmission gear 62 is in meshing transmission with the tooth disc 61. A second transmission gear 631 is fixedly connected to the side wall of the rotating rod 63. The second transmission gear 631 is in meshing transmission with the first transmission gear 62. A top impact hammer 611 for impacting the top of the high-voltage switchgear 7 to be measured is fixedly connected to the side wall of the tooth disc 61. A side impact hammer 632 for impacting the side of the high-voltage switchgear 7 to be measured is fixedly connected to the lower end of the rotating rod 63.

[0063] The lifting cylinder 41 (model number TN16X20S) drives the lifting seat 5 to lift and lower. The rotation of the tooth disc 61 drives the first transmission gear 62 to rotate. The first transmission gear 62 drives the rotating rod 63 to rotate through the second transmission gear 631, so that the top impact hammer 611 and the side impact hammer 632 respectively impact the top and side of the high-voltage switchgear, and the impact area is more comprehensive, and the airtightness of the high-voltage switchgear after being impacted can be detected.

[0064] As Figure 1 , Figure 2As shown in the figure, a servo motor 51 is fixedly connected to the lower end of the lifting seat 5. The output end of the servo motor 51 is fixedly connected to a first driving gear 511. A connecting rod 64 is fixedly connected between two sets of toothed discs 61. A second driving gear 641 is fixedly connected to the side wall of the connecting rod 64. The connecting rod 64, the first driving gear 511 and the toothed disc 61 share the same axis. The second driving gear 641 is in meshing transmission with the first driving gear 511.

[0065] The servo motor 51 (model number 110ST-M05030) drives the first driving gear 511 to rotate back and forth by a certain angle, causing the second driving gear 641 to drive the connecting rod 64 to rotate by a certain angle. The outer diameters of the teeth of the first driving gear 511, the second driving gear 641, the toothed disc 61, the first transmission gear 62 and the second transmission gear 631 are the same. Therefore, all of them rotate by the same angle, avoiding structural jamming and inability to operate due to different angles, and enabling the top impact hammer 611 and the side impact hammer 632 to synchronously impact the high-voltage switchgear.

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

[0067] Sufficient nitrogen-containing gas is filled into the high-voltage switchgear 7 to be tested. A gas pressure detection instrument is used to detect the pressure inside the high-voltage switchgear at this time. The high-voltage switchgear 7 filled with nitrogen-containing gas is placed on the upper end of the support seat 3. When the double clamping assembly clamps the high-voltage switchgear 7 to be tested, due to the existence of the one-way driving assembly, the vibration assembly does not operate at this time, and the impact assembly is not activated, which can simulate the clamping and extrusion conditions encountered during the handling or transportation of the high-voltage switchgear; when the double clamping assembly clamps the high-voltage switchgear 7 to be tested, the vibration assembly does not operate at this time, and the impact assembly is activated, which can simulate the impact conditions encountered during the handling or transportation of the high-voltage switchgear; when the double clamping assembly releases the clamping of the high-voltage switchgear 7 to be tested, the vibration assembly is driven to operate at this time, and the impact assembly is not activated. The vibration assembly vibrates the machine base 1 during the process of the double clamping assembly releasing, thereby causing the high-voltage switchgear to vibrate, simulating the vibration conditions encountered by the high-voltage switchgear; the cooperation between multiple components can intelligently simulate the accidental conditions of the high-voltage switchgear encountering impact, vibration and extrusion, compare the gas pressure inside the high-voltage switchgear before and after the detection, and thus detect the airtightness of the high-voltage switchgear after encountering accidental conditions, and more accurately judge the airtightness quality of the high-voltage switchgear. The detection environment and functions are more comprehensive.

[0068] The above shows and describes 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 by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
