Description

Technical Field

[0001] The present application relates to the field of vacuum circuit breakers, and in particular to a pole-mounted vacuum circuit breaker, a production process, a detection method and a storage medium. Background Art

[0002] The pole-mounted vacuum circuit breaker is a switching device used to realize ring network power supply. Its main function is to connect multiple power sources into a ring power supply system to improve the reliability and flexibility of power supply.

[0003] There are multiple mechanisms installed in the pole-mounted vacuum circuit breaker, such as vacuum interrupter, operating mechanism, protection CT, zero-sequence CT, etc. The operating mechanism is a mechanism for the staff to operate to open and close the circuit. The operating mechanism often includes energy storage components or amplifying components to amplify the force applied by the staff for faster opening and closing and reducing arcs.

[0004] When the contacts open and close in the vacuum interrupter, arcs are inevitably generated. Faster opening can effectively shorten the arc existence time. However, too fast opening will cause the contacts to stop suddenly when they reach the maximum displacement distance, and the reaction force can easily cause damage to the contacts themselves. Summary of the invention

[0005] In order to improve the problem that too fast opening of the circuit breaker may easily cause damage to the contacts, the present application provides a pole-mounted vacuum circuit breaker, a production process, a detection method and a storage medium.

[0006] The present application provides a pole-mounted vacuum circuit breaker, which adopts the following technical solution:

[0007] A pole-mounted vacuum circuit breaker comprises a shell, a plurality of vacuum arc extinguishing piles are arranged on the shell, a vacuum arc extinguishing chamber is formed in the vacuum arc extinguishing pile, a static contact and a moving contact for controlling on and off are arranged in the vacuum arc extinguishing chamber, an operating mechanism for controlling the displacement of the moving contact for opening and closing is located in the shell, an energy storage arm is slidably arranged in the vacuum arc extinguishing pile, an energy storage cavity is opened on the energy storage arm, an energy storage head inserted and slid in the energy storage cavity is arranged on the moving contact, an energy storage spring is arranged in the energy storage cavity, the energy storage spring abuts on the energy storage head to push the energy storage head to move toward the opening surface of the energy storage cavity, an energy storage block is telescopically arranged on the inner wall of the energy storage cavity, and an energy storage rod for pushing the energy storage block into the energy storage head for limiting is arranged on the energy storage arm.

[0008] By adopting the above technical solution, the energy storage head is clamped through the energy storage block so that the energy storage spring can store energy and stretch. Then, after reaching the trigger position, the moving contact is quickly disconnected from the static contact to reduce the probability of arc occurrence. At the same time, after moving to a certain position, the energy storage spring can also be used for buffering, thereby protecting the moving contact and reducing the probability of the reaction force affecting the moving contact.

[0009] Optionally, a clamping block is telescopically provided on the inner wall of the energy storage chamber, a guiding slope is formed on the side wall of the clamping block, the energy storage head is used to interfere with the guiding slope to guide the clamping block to withdraw from the energy storage chamber, the clamping block is used to clamp the energy storage head, a trigger ring is provided in the vacuum arc extinguishing chamber, a clamping rod is slidably provided on the energy storage arm, the trigger ring is used to push the clamping rod to slide, and the clamping rod is used to push the clamping block to withdraw from the energy storage chamber to release the clamping limit of the energy storage head by the clamping block.

[0010] By adopting the above technical solution, the energy storage head after the opening switch is released is clamped by the clamping block to realize the storage of the compressed energy of the energy storage spring, and then release it when closing the switch. Through the height position of the clamping block, the kinetic energy that can be released by the energy storage spring when the moving contact is closed can be accurately calculated and controlled, thereby ensuring that the moving contact can be closed at the same speed every time the switch is closed, and reducing the probability of the moving contact being damaged by collision with the static contact due to excessive closing speed, thereby playing a protective role.

[0011] Optionally, a resistance block is provided on the inner wall of the energy storage cavity, and the resistance block is used to force the energy storage head to resist against the clamping block.

[0012] By adopting the above technical solution, when the energy storage arm approaches the static contact to close the switch, since the energy storage arm is the party that actively applies external force relative to the energy storage head, and the force is transmitted through the energy storage spring, and the spring will inevitably produce a certain hysteresis when transmitting the external force, the energy storage head will lag behind a certain distance relative to the transmission direction of the energy storage arm, and a gap will be generated between the energy storage head and the clamping block, so that when releasing kinetic energy, it is impossible to ensure that the distance position of the energy storage head is the same each time; therefore, the energy storage head is abutted against the clamping block by the abutment block, so that the clamping block can be released at the same height position each time, further ensuring the same kinetic energy and the size of the kinetic energy when the moving contact is closed.

[0013] Optionally, the resistance block is slidably arranged on the inner wall of the energy storage cavity along the sliding direction of the energy storage head, a push rod is slidably arranged on the energy storage arm, the trigger ring is used to push the push rod to slide, and a push block is also slidably arranged on the inner wall of the energy storage cavity, an ejection slope is formed on the push block, the ejection slope is used to push the resistance block to make the energy storage head resist against the clamping block, and the push rod is used to push the push block to push the ejection slope onto the resistance block.

[0014] By adopting the above technical solution, the sliding resistance block reduces the impact of the energy storage head on the resistance block, and also reduces the reaction force of the resistance block on the energy storage head, thereby playing a protective role. At the same time, when the switch is closed, the resistance block is lifted up by the push rod and the push block, so that the resistance block pushes the energy storage head to the specified position, thereby ensuring the normal operation of the resistance block.

[0015] The present application provides a production process for a pole-mounted vacuum circuit breaker, which adopts the following technical solution:

[0016] A production process for a pole-mounted vacuum circuit breaker, comprising:

[0017] Generate material unloading task orders, generate work dispatch orders and dispatch them;

[0033] A result signal is determined by the motion detection range value and a preset motion range threshold and outputted.

[0034] By adopting the above technical solution, it is possible to automatically detect whether the position of the product is correct, and it is also possible to automatically detect whether the working process of the product is qualified during live debugging. This is convenient and fast, improves efficiency, increases the degree of automation, reduces labor costs, and reduces errors caused by manpower.

[0035] Optional, including:

[0036] Get the detection items;

[0037] Determine the shooting speed value and the shooting time value through the detection items and the preset working cycle threshold value;

[0038] The frequency of acquiring the detection image is determined by the shooting speed value, and the shooting time value is at least greater than two of the working cycle thresholds.

[0039] By adopting the above technical solution, the recognition speed and time can be adjusted for different mechanisms in different processes. At the same time, taking photos instead of videos can reduce the required storage space and reduce costs.

[0040] Optional, including:

[0041] Determine a first time value and a retake time value according to the shooting time value;

[0045] The frequency of acquiring the detection image at this time is determined by the reshoot speed value and the reshoot time value.

[0046] By adopting the above technical solution, the actual location and time point where shooting is required are first identified, and then shooting is performed only when necessary, thereby reducing the number of useless photos in continuous shooting, reducing the working pressure of the shooting equipment, extending the equipment life, and improving efficiency.

[0047] The present application provides a computer-readable storage medium, which adopts the following technical solution:

[0064] The following is combined with Figure 1-9 This application is described in further detail.

[0065] The present application embodiment discloses a pole mounted vacuum circuit breaker. Figure 1 and Figure 2The pole-mounted vacuum circuit breaker includes a shell 1, on which a plurality of vacuum arc-extinguishing piles 11 are installed, a vacuum arc-extinguishing chamber 12 is formed in the vacuum arc-extinguishing piles 11, a stationary contact 13 and a moving contact 14 for controlling on and off are installed in the vacuum arc-extinguishing chamber 12, the vacuum arc-extinguishing chamber 12 is used to extinguish the arc on the stationary contact 13 and the moving contact 14, and an operating mechanism for controlling the displacement of the moving contact 14 for opening and closing is located in the shell 1. An energy storage arm 2 slides in the vacuum arc extinguishing pile 11, and the end of the energy storage arm 2 away from the moving contact 14 is connected to the operating mechanism. The staff controls the sliding of the energy storage arm 2 through the operating mechanism. An energy storage cavity 21 is provided on the end of the energy storage arm 2 close to the moving contact 14, and the energy storage cavity 21 extends along the sliding direction of the moving contact 14. An energy storage head 22 is fixedly connected to the end of the moving contact 14 away from the static contact 13, which is inserted into and slides in the energy storage cavity 21. The outer wall of the energy storage head 22 slides on the inner wall of the energy storage cavity 21 in a fit, and the diameter of the opening surface of the energy storage cavity 21 is smaller than the cross-sectional diameter of the internal space of the energy storage cavity 21. The diameter of the end of the energy storage head 22 is adapted to the diameter of the internal space of the energy storage cavity 21, that is, the diameter of the end of the energy storage head 22 is larger than the diameter of the opening surface of the energy storage cavity 21, so that the energy storage head 22 is difficult to withdraw from the energy storage cavity 21, and the rod diameter of the energy storage head 22 is adapted to the diameter of the opening surface of the energy storage cavity 21. An energy storage spring 23 is installed in the energy storage cavity 21, one end of the energy storage spring 23 abuts against the bottom wall of the energy storage cavity 21 facing its own opening surface, and the other end of the energy storage spring 23 abuts against the side wall of the energy storage head 22 facing the bottom wall of the energy storage cavity 21. The energy storage spring 23 expands and contracts along the sliding direction of the energy storage head 22. When the energy storage head 22 is at half the depth of the energy storage cavity 21 and close to the opening surface of the energy storage cavity 21, the energy storage spring 23 is in a balanced state.

[0066] Reference Figure 3A trigger ring 311 is fixedly connected to the inner wall of the vacuum interrupter 12. The trigger ring 311 is hollow and annular. The rod of the energy storage head 22 passes through the hollow center of the trigger ring 311, and the outer wall of the rod of the energy storage head 22 fits the inner wall of the trigger ring 311. An energy storage groove 241 is provided on the inner side wall of the trigger ring 311. An energy storage block 24 slides in the energy storage groove 241. An energy storage slot 242 is provided on the rod of the energy storage head 22. The opening direction of the energy storage slot 242 is perpendicular to the sliding direction of the energy storage head 22. The end of the energy storage block 24 extends out of the energy storage groove 241 and is used to be inserted into the energy storage slot 242. A reset slope 243 is formed on the end of the energy storage block 24 outside the energy storage groove 241. The reset slope 243 is formed on the side wall of the energy storage block 24 facing the energy storage arm 2. The reset slope 243 is inclined in a direction that the closer it is to the energy storage groove 241 and the closer it is to the energy storage arm 2. An energy storage rod 25 is fixedly connected to the outer wall of the energy storage arm 2, and a control groove 244 is also provided on the side wall of the energy storage block 24 facing the energy storage arm 2. The control groove 244 is located on the energy storage block 24 in the energy storage groove 241, and the side wall of the control groove 244 away from the opening surface of the energy storage groove 241 is inclined. The inclined inner wall of the control groove 244 is inclined in a direction that is farther away from the opening surface of the control groove 244 and closer to the rod portion of the energy storage head 22. The energy storage rod 25 is used to abut against the inclined inner wall of the control groove 244 to push the energy storage block 24 into the energy storage head 22 for limiting. A limiting spring 245 is also installed in the energy storage groove 241, one end of the limiting spring 245 abuts against the bottom wall of the energy storage groove 241 facing its own opening surface, and the other end of the limiting spring 245 abuts against the end of the energy storage block 24 that penetrates into the energy storage groove 241, and the limiting spring 245 retracts and contracts in a direction of pushing the energy storage block 24 out of the energy storage groove 241.

[0067] Reference Figure 4 and Figure 5A clamping groove 312 is provided on the inner wall of the energy storage cavity 21, and the clamping groove 312 extends in a direction away from the energy storage cavity 21, and the opening direction of the clamping groove 312 is perpendicular to the opening direction of the energy storage cavity 21. A clamping block 3 slides in the clamping groove 312, and the end of the clamping block 3 extending out of the clamping groove 312 is used to abut against the end of the energy storage head 22, and the clamping block 3 is located in the energy storage cavity 21 and is formed with a guiding slope 31 on the side wall facing the opening surface of the energy storage cavity 21. The guiding slope 31 is inclined in a direction in which the deeper the clamping groove 312 is, the closer it is to the opening surface of the energy storage cavity 21. The end of the energy storage head 22 away from the moving contact 14 is used to abut against the guiding slope 31 to guide the clamping block 3 to completely retreat into the clamping groove 312, so as to make way for the energy storage head 22 to slide in the direction of continuing to penetrate into the energy storage cavity 21. The side wall of the clamping block 3 facing away from the energy storage cavity 21 is used to abut against and clamp on the side wall of the energy storage head 22 facing the energy storage cavity 21 to limit the energy storage head 22 from sliding out of the energy storage cavity 21. A clamping rod 32 slides inside the energy storage arm 2, and one end of the clamping rod 32 slides into the clamping groove 312, and the other end of the clamping rod 32 extends out of the energy storage arm 2, and the clamping rod 32 is located on the side wall of the energy storage arm 2 close to the trigger ring 311. A guide groove 313 is provided on the side wall of the clamping block 3 facing the trigger ring 311. The guide groove 313 is inclined away from the inner wall of the energy storage chamber 21. The inclined guide groove 313 is inclined in a direction that is closer to the opening surface of the guide groove 313 as it is away from the energy storage chamber 21. The trigger ring 311 is used to push the clamping rod 32 to slide in the direction of penetrating into the clamping groove 312 and abutting against the inclined inner wall of the guide groove 313. The clamping rod 32 pushes the clamping block 3 to completely retreat into the clamping groove 312, thereby withdrawing from the energy storage chamber 21 to release the clamping limit of the clamping block 3 on the energy storage head 22.

[0068] Reference Figure 3 and Figure 4 and Figure 5A resistance slide groove 411 is opened on the inner wall of the energy storage cavity 21, and the opening direction of the resistance slide groove 411 is parallel to the opening direction of the energy storage cavity 21. A resistance block 4 slides in the resistance slide groove 411, and the resistance block 4 slides along the sliding direction of the energy storage head 22. The end of the resistance block 4 extends from the resistance slide groove 411 into the energy storage cavity 21 to resist the end of the energy storage head 22. The resistance block 4 is used to resist the energy storage head 22 on the clamping block 3. The lifting groove 44 is provided on the inner wall of the bottom wall of the resistance slide groove 411 facing its own opening surface. The opening direction of the lifting groove 44 is perpendicular to the sliding direction of the resistance block 4. The lifting groove 44 extends and opens in the direction away from the energy storage cavity 21. A top block 42 slides in the lifting groove 44. The top block 42 slides in the direction away from or close to the resistance slide groove 411. The top block 42 interacts along the direction of sliding into and out of the resistance slide groove 411, and the sliding plane of the top block 42 is flush with the bottom surface of the resistance slide groove 411 away from the opening surface of the energy storage cavity 21. An ejection slope 43 is formed on the end of the top block 42 that slides into the resistance slide groove 411. The ejection slope 43 is inclined in a direction away from the opening surface of the energy storage cavity 21 and away from the bottom wall of the lifting groove 44. The ejection slope 43 is used to abut on the resistance block 4 to lift the resistance block 4 in the direction close to the opening surface of the energy storage cavity 21, thereby causing the energy storage head 22 to abut on the clamping block 3. The abutment block 4 can slide in the abutment groove 411 by other limiting sliding modes, for example, a limiting sliding mode in which the limiting block cooperates with the limiting groove, or a limiting sliding mode in which the guide rod cooperates with the guide groove.

[0069] Reference Figure 3 and Figure 5 A push rod 41 is also slidably arranged in the energy storage arm 2, one end of the push rod 41 extends from the end of the energy storage arm 2 close to the trigger ring 311, and the other end of the push rod 41 extends into the lifting groove 44. A lifting top groove 451 is provided on the side wall of the top block 42 facing the trigger ring 311, and the lifting top groove 451 is inclined on the inner wall close to the energy storage chamber 21. The inner wall of the inclined lifting top groove 451 is inclined in a direction closer to the bottom wall of the lifting groove 44 as it moves away from the trigger ring 311. The trigger ring 311 pushes the push rod 41, and the push rod 41 is used to push in the inclined lifting top groove 451 to push the top block 42 to be inserted between the resistance block 4 and the ground of the resistance slide groove 411, thereby lifting the resistance block 4, and the push rod 41 can pass through the lifting top groove 451 and then penetrate the top block 42.

[0070] The implementation principle of a pole-mounted vacuum circuit breaker in an embodiment of the present application is as follows: when opening is required, the operating mechanism pulls the energy storage arm 2 in a direction away from the static contact 13, and the energy storage block 24 is inserted into the rod portion of the energy storage head 22 to limit the movement of the energy storage head 22, thereby pulling the energy storage spring 23 to stretch for further energy storage. When the energy storage rod 25 is pulled out of the energy storage slot 242, the limit spring 245 pulls the energy storage block 24 into the energy storage slot 241, releases the limit on the rod portion of the energy storage head 22, and the energy storage head 22 drives the moving contact 14 to open the gate instantly under the action of the energy storage spring 23. At the same time, when the energy storage head 22 moves to a certain distance, it is buffered by the energy storage spring 23. At this time, the energy storage head 22 passes over the clamping block 3 and is clamped, and the energy storage spring 23 is kept in a compressed state.

[0071] When the circuit breaker needs to be closed, the operating mechanism pulls the energy storage arm 2 to move it in the direction close to the static contact 13. The displacement of the energy storage arm 2 pushes the energy storage spring 23, and the energy storage head 22 pushes the moving contact 14 close to the static contact 13. When the energy storage arm 2 moves to the push rod 41 and presses on the trigger ring 311, it continues to move. The push rod 41 pushes the push block 42, and the push block 42 pushes the contact block 4 to press the energy storage head 22 against the clamping block 3. Then the clamping rod 32 presses on the trigger ring 311 and continues to move. The clamping rod 32 pushes the guide slope 31, driving the clamping block 3 to move and release the restriction on the energy storage head 22. At this time, the clamping rod 32 presses against the trigger ring 311, the energy storage arm 2 stops moving, and the energy storage head 22 pops out to close the circuit breaker under the elastic force of the energy storage spring 23.

[0072] The present application embodiment discloses a production process of a pole mounted vacuum circuit breaker. Figure 6 , the production process of the pole mounted vacuum circuit breaker includes the following steps:

[0073] S1. Generate a material unloading task order, generate a work order and dispatch it;

[0074] S11, check the appearance dimensions of the housing 1 and record them on the material requisition sheet;

[0075] S12, assembling the vacuum arc extinguishing pile 11 and inspecting it;

[0076] S13, assembling the operating mechanism, the energy storage arm 2 and the energy storage head 22 and inspecting them;

[0081] S18. Carry out power-on debugging, which includes live testing, opening and closing testing, and insulation withstand voltage testing;

[0082] S19, put into storage after labeling, packaging and boxing.

[0083] In detail: The inspection should be carried out according to the drawings, processes and standards. The inspection should also include self-inspection during the operation, self-classification of products, and self-signature after processing. The inspection should also implement self-inspection by staff of the current process, mutual inspection between different staff, and irregular spot checks by full-time inspection staff. Inspection can also be carried out in conjunction with automated inspection. For example, image recognition can be performed through a camera, and then compared with standard parts in the database to determine whether it meets the standards.

[0084] The present application embodiment discloses a detection method for a pole-mounted vacuum circuit breaker. Figure 7 , the detection method of the pole-mounted vacuum circuit breaker includes the following steps:

[0085] Acquire multiple detection images;

[0086] S2, determining a regional detection image by detecting an image and a preset detection area;

[0087] S21, determining a motion detection range value by using multiple area detection images and a preset recognition threshold;

[0088] S22. Determine a result signal based on the motion detection range value and a preset motion range threshold and output it.

[0089] In detail: the recognition threshold is used to identify the image data of the mechanism corresponding to the current process, such as the color threshold of the operating rod of the operating mechanism to identify the operating rod; the motion detection range value is the maximum motion range of the identified mechanism, that is, the recognition is performed within the area detection image through the recognition threshold. The area detection image can be a video or a continuous photo. For example, in the xy coordinate system, the operating rod moves from (-10,0) to (10,0), then the motion detection range value is (-10,0) to (10,0), and the motion range threshold is the standard motion range of qualified products. The result signal can be obtained by comparison. Assuming the allowable error is 1%, the motion range threshold is (-10,0) to (10,0), 10-(-10)=20, 20*1%=0.2, then the motion detection range value is between (-10±0.2,0) and (10±0.2,0) and all are qualified products, and a qualified result signal is output. If it exceeds this range, an unqualified result signal is output.

[0090] Reference Figure 8 , further comprising the following steps:

[0091] S3, obtaining detection items;

[0092] S31, determining a shooting speed value and a shooting time value through a detection item and a preset working cycle threshold;

[0093] S32. Determine the frequency of acquiring the detection image according to the shooting speed value, and the shooting time value is at least greater than two working cycle thresholds.

[0094] In detail: The working cycle threshold is the cycle time of one round trip movement of the mechanism of the current process. For example, if the detection item is the operating lever of the operating mechanism and the working cycle threshold is 2s, the shooting time value can be calculated as 6s. If at least 30 photos are required for calculation, the shooting speed value can be 5 times / s, that is, one photo every 0.2s. Or if 20 photos are required in each working cycle, the shooting speed value can be 10 times / s, that is, one photo every 0.1s.

[0098] S42, determining a limit time range value according to the motion detection range value and the first time value;

[0099] S43, determining a reshooting speed value and a reshooting time value according to the limit time range value and the shooting speed value;

[0100] S44. Determine the frequency of acquiring the detection image at this time according to the reshooting speed value and the reshooting time value.

[0101] In detail: the first time value and the retake time value are both time values ​​greater than a working cycle threshold, which are used to determine the movement limit position of the mechanism, that is, to determine the range of movement through a working cycle, that is, the motion detection range value, and then determine the approximate time interval for the next movement of the mechanism to the limit through the first time value corresponding to the limit position of this range, that is, the limit time range value. For example, if the shooting time value is 6s, the shooting time value and the retake time value can be 3s respectively, and the motion detection range value is (-10,0) to (10,0). If the allowable range is 10%, the limit time range value corresponding to the movement of the mechanism to x is -10±2 and 10±2 is calculated. If the limit time range value is 0-0.2s and 1-1.2s, then after adding the working cycle threshold, 4-4.2s and 5-5.2s can be obtained. Then, the next time shooting can be performed within these two time ranges, and shooting can be omitted at other times. On this basis, new retake speed values ​​and retake time values ​​are determined to save storage space and reduce the number of shots, thereby ensuring the working life of the camera.
