Description

Technical Field

[0001] The present invention relates to the technical field of line testing, and in particular to an intelligent switch cabinet line testing device and a detection method. Background Art

[0002] Low voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other industries for power transmission, distribution and power conversion;

[0003] Most of the lines in the switch cabinet are connected by busbars. Busbars refer to the copper or aluminum busbars that connect the main switch in the cabinet and the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to serve as a conductor. The insulation performance of the busbar is crucial. If the insulation performance of the busbar is not ideal, safety accidents are very likely to occur, and there are major safety hazards. Therefore, it is necessary to conduct insulation testing on it to ensure the stability of the subsequent operation of the busbar.

[0004] A power transmission and transformation line insulation test device disclosed in a patent application with reference publication number CN115792286A, which pushes a push plate to move a rigid pull rope, thereby quickly opening a metal block, allowing people to place the line, and then detect the line through a current detection unit, thereby improving detection efficiency and reducing operation difficulty.

[0005] The above-mentioned test device can well complete the test work on the line through the cooperation of the current detection unit and the metal block. However, during the test process, the above-mentioned test device needs to manually pull the line to complete the reciprocating test work, which increases the difficulty of the test. In addition, the line is very likely to be damaged during the pulling process, which poses a safety hazard.

[0006] At the same time, the above-mentioned test device has great limitations in its testing. It cannot simulate the external environment during the test, so it is impossible to know the fluctuation of the insulation performance of the busbar, cannot test the interference of the external environment on the insulation state, and cannot complete the test on the insulation weaknesses of the busbar, which is not conducive to the subsequent improvement and upgrading of the busbar insulation structure and affects the performance of the busbar.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0044] Embodiment 1: The present invention provides a technical solution: Figures 1 to 13As shown, an intelligent switch cabinet line test device includes a test bench 1, on the upper surface of the test bench 1 are symmetrically and detachably installed two manual slides 2, at the output ends of the two manual slides 2 are installed clamps 3, the clamps 3 use a vise clamp or an electric clamp to complete the clamping work, and the clamps 3 are insulated, and a busbar 4 is detachably installed between the two clamps 3, an L-shaped seat 5 is installed on the upper surface of the test bench 1 between the two manual slides 2, a reciprocating mechanism is installed on one side of the L-shaped seat 5, and a synchronous test mechanism is slidably installed on the other side of the L-shaped seat 5, the synchronous test mechanism is used to complete a synchronous flexible test action on the upper and lower surfaces of the busbar 4, the reciprocating mechanism is used to drive the synchronous test mechanism to move to complete the reciprocating test work, and the reciprocating mechanism and the synchronous test mechanism are slidably installed. A connection mechanism is installed between them, and the reciprocating mechanism and the synchronous test mechanism are connected with each other by the connection mechanism. A control console is installed on one side of the upper surface of the test bench 1. The control console establishes connections with the reciprocating mechanism, the synchronous test mechanism and the connection mechanism to complete the control. A test power supply is installed on one side of the upper surface of the test bench 1. Two power clamps are installed at the output end of the test power supply. The two power clamps are electrically connected to the two ends of the busbar 4. At the same time, the busbar 4 can be powered on by connecting an external power supply through a wire to complete the test. The reciprocating mechanism includes synchronous wheels 6 symmetrically rotated and installed on both sides of the inner wall of the L-shaped seat 5 through a bracket. A synchronous belt 7 is provided on the common transmission sleeve outside the two synchronous wheels 6, and a reciprocating motor 8 is installed on one side of the L-shaped seat 5 through a bracket. The output end of the reciprocating motor 8 is connected to one of the synchronous wheels 6 by transmission.

[0045] It is worth noting that when performing a reciprocating test: by providing a reciprocating mechanism, when the two test contacts 42 are in contact with the busbar component 4, the reciprocating motor 8 is started to drive the synchronous belt 7 to rotate, and the power of the synchronous belt 7 is transmitted to the test contact 42 via the power arm 15, so that the test contact 42 follows the adjustment seat 11 to slide on the slide 9 to complete the movement of the test station, and the busbar component 4 can be tested for movement. When it moves to the extreme position of the busbar component 4, the reciprocating motor 8 reverses, driving the synchronous belt 7 and the test contact 42 to reset and move, thereby completing the reciprocating test of the busbar component 4, improving the test accuracy, enriching the test data, and facilitating subsequent research and development upgrades.

[0046] Among them, electrical components such as the reciprocating motor 8, the tester 39, the double-sided electromagnet 12, etc. are all connected to switches through wires, and the switches are electrically connected to a controller. The specific structure of the controller is not limited. An absolute encoder is installed on the reciprocating motor 8 for accurately positioning the reciprocating motor 8.

[0047] Embodiment 2: Based on the synchronization testing mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the synchronization testing mechanism.

[0048] like Figures 6 to 8As shown, the synchronous testing mechanism includes a No. 1 zone 31 opened at the front end of the adjustment seat 11, a No. 2 zone 32 is arranged in communication with the No. 1 zone 31 in the adjustment seat 11, a gear 33 is rotatably installed in the middle position of the No. 2 zone 32, and a No. 1 rack 34 and a No. 2 rack 35 are symmetrically installed on both sides of the inner wall of the No. 2 zone 32, the No. 1 rack 34 and the No. 2 rack 35 are slidably arranged in the No. 2 zone 32, the No. 1 rack 34 and the No. 2 rack 35 are both meshed with the gear 33, a No. 1 shift block is installed on the top of the No. 1 rack 34, the No. 1 shift block is slidably engaged in the No. 2 zone 32, a No. 2 shift block is installed on the top of the No. 2 rack 35, and the No. 2 shift block is installed on the top of the No. 2 rack 35. The No. 1 shift block is slidably engaged in the No. 2 zone 32, and an electric push rod 36 is installed on the top of the No. 2 zone 32. The output end of the electric push rod 36 is transmission-connected to the No. 1 shift block, and two lifting blocks 37 are symmetrically slidably installed in the No. 1 zone 31. The two lifting blocks 37 are detachably fixedly connected to the No. 1 rack 34 and the No. 2 rack 35, respectively. Test units are detachably installed on the two lifting blocks 37. The two test units extend to the upper and lower surfaces of the busbar 4 to complete synchronous testing. A cross arm 38 is extended and installed at the bottom of the slider 10, and a tester 39 is installed on the cross arm 38. The tester 39 is specifically an insulation tester 39;

[0049] It is worth noting that when conducting the test: a synchronous testing mechanism is provided, the busbar component 4 is clamped by using the clamp 3, and then the height of the busbar component 4 is finely adjusted by operating the manual slide 2 to ensure that the busbar component 4 and the two test units maintain a suitable test position, and then the power clamp is electrically connected to the two ends of the busbar component 4. At the same time, an external power supply can be used to power on the test work, and the technicians can choose freely, and then start the electric push rod 36 to push the No. 1 shift block and the No. 1 rack 34 to move downward and slide in the No. 2 area 32. Guided by the gear 33, the No. 2 rack 35 moves upward and slides in the No. 2 area 32, and then the power is transmitted to the two test units through the two lifting blocks 37, so that the two test units can approach and move away from each other. Adjustment is convenient for completing adjustment for busbar components 4 of different thicknesses. Afterwards, under the drive of the electric push rod 36, the two test contacts 42 are made to contact with the busbar component 4. At the same time, the two test contacts 42 are connected to the tester 39. Therefore, the insulation state on the busbar component 4 can be collected through the two test contacts 42. At the same time, under the guidance of the flexible rod 44 and the flexible spring 45, the test contact 42 can be flexibly contacted with the busbar component 4, ensuring the safety of the test and avoiding the damage of the busbar component 4 caused by rigid contact and causing interference to the test results. At the same time, the test contact 42 can be close to the busbar component 4, ensuring the test accuracy, and the two guide rods 43 can actively guide the up and down movement of the test contact 42;

[0050] In the embodiment of the present invention, each test unit includes a transverse plate 40, which is detachably fixedly connected to the lifting block 37, and the transverse plate 40 extends to the busbar component 4. Mounting seats 41 are installed at intervals on the side of the transverse plate 40 facing the busbar component 4, and test contacts 42 are detachably installed on the mounting seats 41. The test contacts 42 are electrically connected to the tester 39. Two guide rods 43 are symmetrically installed on the back of the mounting seat 41. The two guide rods 43 slide through the transverse plate 40 correspondingly, and a No. 1 plug is installed at the tail of the two guide rods 43. A flexible rod 44 is installed in the middle position of the back of the mounting seat 41. The flexible rod 44 slides through the transverse plate 40 correspondingly, and a No. 2 plug is installed at the tail of the flexible rod 44. A flexible spring 45 is sleeved on the outside of the flexible rod 44, and the flexible spring 45 is located between the mounting seat 41 and the transverse plate 40. The flexible spring 45 is used to keep the test contact 42 and the busbar component 4 in a flexible test state.

[0051] Embodiment 3: Based on the connection mechanism provided in Embodiment 1, this embodiment provides a further technical solution of the connection mechanism.

[0052] like Figures 9 to 13 As shown, the connection mechanism includes a slideway 9 that penetrates and is opened on the L-shaped seat 5, a slider 10 is slidably installed in the slideway 9, and an adjustment seat 11 is vertically installed on the upper surface of the slider 10, and double-sided electromagnets 12 are installed on both sides of the bottom of the adjustment seat 11 through brackets. The double-sided electromagnets 12 can be adsorbed at the top and bottom after being energized, and a guide member 13 is installed on the back of the adjustment seat 11. A connection arm 14 is slidably engaged with the guide member 13, and a guide track that cooperates with the guide member 13 is opened on the connection arm 14. A power arm 15 is installed on the back, and the power arm 15 is detachably fixedly connected to the synchronous belt 7. At the same time, a push arm 16 and a push arm 17 are installed on the top of both sides of the connecting arm 14. The push arm 16 and the push arm 17 are respectively in contact with the side wall of the adjustment seat 11 to complete the pushing work. The push arm 16 and the push arm 17 are made of iron material. The push arm 16 and the push arm 17 are in contact with the double-sided electromagnet 12 to complete the adsorption, and the push arm 16 and the push arm 17 are both installed with a flexible pad on the side facing the adjustment seat 11;

[0053] It is worth noting that: when simulating the working environment: a connecting mechanism is provided to connect the external hot air with the air inlet pipe 20, and the subsequent hot air is sprayed to the surface of the busbar component 4 through the spray chamber 19, thereby simulating the interference of the external environment on the insulation performance of the busbar component 4. The temperature of the hot air can be freely adjusted according to actual needs. At the same time, a temperature sensor can be added to the busbar component 4 to obtain the temperature data of the busbar component 4. When the synchronous belt 7 moves, the connecting arm 14 is pulled to move by the power arm 15. Since the connecting arm 14 and the adjustment seat 11 complete the sliding guidance through the guide member 13, the power of the synchronous belt 7 first acts on the connecting arm 14, that is, when the synchronous belt 7 moves in the forward direction, the connecting arm 14 slides until the No. 1 push arm 16 contacts the side wall of the adjustment seat 11. When the synchronous belt 7 moves in the reset direction, the connecting arm 14 slides until the No. 2 push arm 17 contacts the side wall of the adjustment seat 11. Under this action, the spray chamber 19 follows the connecting arm 14 to switch freely on the left and right sides of the test unit, so that the connecting arm 14 follows the moving direction of the reciprocating mechanism to complete the early conversion, and the hanging arm 18 and the spray chamber 19 on it are linked to follow the movement, so that the spray chamber 19 switches the working position in advance, ensuring that the spray chamber 19 is always in front of the moving direction, ensuring the continuous supply of heat, and when the spray chamber 19 is switched, the No. 1 push arm 16 or the No. 2 push arm 17 contacts the adjustment seat 11 to complete the promotion work of the subsequent moving action;

[0054] In the embodiment of the present invention, a suspension arm 18 is added to one side of the connecting arm 14, and the suspension arm 18 is arranged across the adjustment seat 11, so that the suspension arm 18 can smoothly complete the switching of the left and right positions of the adjustment seat 11, and a spray chamber 19 is detachably installed on the suspension arm 18. The connecting arm 14 can follow the synchronous belt 7 to complete the active switching of the position of the spray chamber 19. At the same time, a spraying part for heating can be added on the suspension arm 18 through a bracket across the front of the busbar part 4. The spraying part has the same structure as the spray chamber 19. The spraying part is in the same structure as the busbar part 4. The surface is heated accordingly, and the spraying part cooperates with the spray chamber 19 to complete the synchronous heating of the upper and lower surfaces. The technicians can freely add it according to the needs. An air inlet pipe 20 is connected to one side of the top of the spray chamber 19. The air inlet pipe 20 is connected to the external hot air, and the temperature of the hot air is freely set by the external heating source. A control valve for controlling its on and off is installed at the end of the air inlet pipe 20, and a plurality of spray holes are evenly connected to the lower surface of the spray chamber 19 toward the busbar part 4, and the hot air is blown to the busbar part 4 through the plurality of spray holes to complete the simulation test;

[0055] In the embodiment of the present invention, two receiving chambers 21 are symmetrically provided on one side of the slider 10. The receiving chambers 21 are open on the slider 10. A frame 22 and a frame 23 are slidably installed in the two receiving chambers 21, respectively. A friction roller 24 is rotatably installed in the frame 22. A one-way bearing 25 is installed between the bottom of the friction roller 24 and the frame 22. The one-way bearing 25 is used to limit the rotation of the friction roller 24 in one direction, so that the friction roller 24 can only rotate in the same direction. The second friction roller 26 is rotatably installed in the second frame 23, and the inner wall of the slideway 9 is provided with a friction pad that cooperates with the first friction roller 24 and the second friction roller 26. A second one-way bearing 27 is installed between the bottom of the second friction roller 26 and the second frame 23. The second one-way bearing 27 is used to complete the one-way restriction on the rotation of the second friction roller 26, so that the second friction roller 26 can only rotate in one direction. A A plurality of reset springs 28 are used to pull the No. 1 frame 22 and the No. 2 frame 23 to reset into the storage chamber 21, and a No. 1 wedge block 29 is installed on the back of the No. 1 frame 22 and the No. 2 frame 23. Two trigger members 30 are symmetrically installed at the bottom of both sides of the adjustment seat 11. The two trigger members 30 cooperate with the No. 1 frame 22 and the No. 2 frame 23 to complete the switching trigger action. The No. 1 one-way bearing 25 and the No. 2 one-way bearing 27 limit the rotation direction in the opposite direction. When the No. 1 push arm 16 is aligned with the adjustment seat 11, the No. 1 push arm 16 is rotated in the opposite direction to the No. 2 one-way bearing 27. When contacting and pushing, the No. 1 one-way bearing 25 is locked to complete the restricted rotation, and the No. 2 one-way bearing 27 is unlocked to be able to rotate freely and guide. Conversely, when the No. 2 push arm 17 contacts and pushes the adjustment seat 11, the No. 1 one-way bearing 25 is unlocked to be able to rotate freely, and the No. 2 one-way bearing 27 is locked to complete the restricted rotation. Through the cooperation of the No. 1 one-way bearing 25 and the No. 2 one-way bearing 27, the No. 1 friction roller 24 and the No. 2 friction roller 26 intermittently move to complete the friction restriction action, so that the adjustment seat 11 remains stable;

[0056] Among them, each trigger member 30 includes a No. 1 plate 301 installed at the bottom of one side of the adjustment seat 11, a lifting arm 302 is slidably penetrated on the No. 1 plate 301, and a No. 2 plate 303 is installed above the No. 1 plate 301 on the outside of the lifting arm 302. The No. 2 plate 303 is detachably fixedly sleeved on the outside of the lifting arm 302, and an extrusion spring 304 is sleeved on the outside of the lifting arm 302, and the elastic strength of the extrusion spring 304 is greater than the elastic strength of the plurality of reset springs 28. The extrusion spring 304 is located between the No. 1 plate 301 and the No. 2 plate 303, and a guide rod is installed on one side of the No. 2 plate 303, and the bottom of the guide rod slides through the No. 1 plate 301 The lifting arm 302 is provided with a second wedge block 305 at the bottom, and the second wedge block 305 cooperates with the first wedge block 29 to complete the extrusion action. A permanent magnet 306 is provided at the top of the lifting arm 302, and the top of the permanent magnet 306 contacts the lower surface of the double-sided electromagnet 12, and the magnetic poles of the permanent magnet 306 repel each other with the double-sided electromagnet 12 after power-on, so as to complete the pushing work. When the first push arm 16 is close to the adjustment seat 11, the double-sided electromagnet 12 pushes the permanent magnet 306 to drive the lifting arm 302 to move downward, and under the guidance of the first wedge block 29 and the second wedge block 305, the first friction roller 24 is hidden in the storage cavity 21;

[0057] It is worth noting that when the slider 10 is frictionally limited: by providing a trigger member 30, when the No. 1 push arm 16 and the No. 2 push arm 17 are not in contact with the adjustment seat 11, the lifting arms 302 of the two trigger members 30 are not triggered at this time, so under the reset action of the extrusion spring 304, the No. 2 wedge block 305 is driven to reset and move upward to squeeze the No. 1 wedge block 29, so that the No. 1 friction roller 24 and the No. 2 friction roller 26 overcome the pulling force of the reset spring 28 and extend out of the storage cavity 21 to frictionally contact the slideway 9, thereby completing the active limit of the slider 10. The first and second friction rollers 24 and 26 have the corresponding one-way bearings 25 and 27 which are in opposite directions, so that the first and second friction rollers 24 and 26 can unlock one moving direction and lock the other moving direction, which is beneficial for subsequent switching. Specifically, when the first push arm 16 contacts the adjustment seat 11, the corresponding double-sided electromagnet 12 is started, and the double-sided electromagnet 12 is used to lock the first push arm 16. 16 completes adsorption to ensure the stability of subsequent pushing, and at the same time completes the extrusion and pushing of the permanent magnet 306, so that the lifting arm 302 overcomes the extrusion spring 304 and drives the second wedge block 305 to move downward. At this time, the first friction roller 24 is pulled by the reset spring 28 to reset to the storage cavity 21 to complete hiding. At the same time, the second friction roller 26 on the other side continues to contact with the slideway 9. However, at this time, under the restriction of the second one-way bearing 27, the second friction roller 26 can follow the forward path of the test unit to complete the rotation guidance, and can reverse the slider 10 The friction limitation during movement can avoid interference. Later, when the No. 2 push arm 17 contacts the adjustment seat 11, the No. 2 friction roller 26 is hidden through the double-sided electromagnet 12. At this time, the No. 1 friction roller 24 completes the rotation guidance in the test moving direction under the limitation of the No. 1 one-way bearing 25, that is, under the action of the No. 1 one-way bearing 25 and the No. 2 one-way bearing 27, the No. 1 friction roller 24 and the No. 2 friction roller 26 complete the mutual cooperation, which can ensure the stability of the slider 10 and can perform rotation guidance, so that the overall test work can be carried out safely and stably.

[0062] Step 4: A connection mechanism is provided, which can actively simulate the external environment and actively heat up the busbar 4.

[0063] The present invention provides an intelligent switch cabinet line test device and detection method, and the specific working principle is as follows: first, the busbar component 4 is placed on two clamps 3 to complete locking and fixing, and the manual slide 2 is operated at the same time to complete the up and down fine adjustment of the test position of the busbar component 4, which is beneficial to the subsequent testing work. By providing a synchronous testing mechanism, two symmetrically arranged test units are used to flexibly contact with the busbar component 4 to complete the synchronous test. The flexible contact design can complete the flexible protection of the test unit and the busbar component 4, thereby improving the testing efficiency;

[0064] At the same time, under the drive of the reciprocating mechanism, the synchronous test mechanism is pulled to move back and forth, thereby completing the reciprocating insulation test operation on the busbar component 4, which is convenient for technicians to operate and use. In order to improve the accuracy of the test, a connection mechanism is provided, which can actively simulate the external environment and actively heat up the busbar component 4, so that in the test path, the busbar component 4 is stably heated up, and can be simulated according to the actual ambient temperature, so as to obtain the insulation performance of the busbar component 4, and can simulate the interference of the working environment on the busbar component 4, thereby improving the safety of the subsequent operation of the busbar component 4;

[0065] In addition, when the connecting mechanism is conducting a reciprocating test with the reciprocating mechanism, the connecting arm 14 thereon can complete intermittent switching work, so that the spray chamber 19 is always at the front end of the test path, ensuring the stability of the temperature rise and improving the test accuracy. There is no need for manual switching, which saves time and effort. The connecting mechanism can complete the free locking action, which ensures the stability of the test action and can actively guide the mobile test, so that the test work can be carried out stably and smoothly.
