Description

Technical Field

[0001] The present invention relates to the technical field of power distribution switchgear, and in particular to an intelligent high-voltage cabinet for an electric shovel with integrated interlocking protection. Background Art

[0002] High-voltage cabinets are key components in power systems used to control, protect, and isolate high-voltage electrical equipment. They are widely used in high-voltage power distribution systems in power plants, substations, and industrial facilities to ensure the safe and reliable operation of power systems.

[0003] High-voltage switchgear involves the operation of high voltages and large currents. Any misoperation can lead to serious safety accidents or equipment damage. Interlock components, through mechanical, electrical, or software control, automatically prevent equipment from starting or continuing to operate under specific conditions until all safety conditions are met. Interlock components prevent misoperation and ensure the safety of personnel and equipment.

[0004] However, the existing intelligent high-voltage cabinets with integrated interlocking protection for electric shovels have the following shortcomings:

[0005] 1) The interlocking device consists of two parts: one for disassembling and assembling the vacuum circuit breaker, and the other for opening and closing the grounding knife. Traditional technology relies mainly on the coordination of related mechanical components to adjust the two interlocking parts in sequence according to the power supply status of the high-voltage cabinet. However, the operation process requires manual assistance. The different interlocking parts cannot achieve autonomous control or interoperability.

[0006] 2) Due to the many limitations of traditional interlocking parts, the adjustment process requires the use of adapter tools, and relevant personnel cannot avoid direct or indirect contact with the cabinet, resulting in the probability of dangerous accidents still cannot be effectively reduced.

[0007] Therefore, we proposed an intelligent high-voltage cabinet with integrated interlocking protection for electric shovel to solve the above problems. Summary of the Invention

[0040] Example 1, according to Figure 1 、 Figure 3-Figure 7As shown, the first interlocking mechanism 4 includes a load-bearing bracket 401, which is fixedly mounted on the front surface of the inner partition 3. Two path grooves 402 and an expansion groove 403 are respectively provided inside the load-bearing bracket 401. Two iron rails 427 are fixedly mounted on the top of the load-bearing bracket 401. Two sliding sleeves 404 are fixedly mounted on the front surface of the inner partition 3. A T-shaped slide 405 is movably provided inside each sliding sleeve 404. A first cross plate 406 is fixedly mounted on the top of each T-shaped slide 405. A group of electric push components 407 are fixedly mounted on the bottom of each first cross plate 406. A plastic insulating rubber pad 408 is fixedly sleeved between the shaft ends of the two electric push components 407, a second horizontal plate 409 is fixedly installed between the opposite sides of the two T-shaped slides 405, and a rangefinder 410 and a linkage controller 411 are fixedly installed on the top and bottom of the second horizontal plate 409 respectively. The output end of the rangefinder 410 is fixedly connected to a first information line 412, and the output end of the first information line 412 is connected to the terminal of the linkage controller 411. The output end of the first information line 412 is fixedly connected to multiple groups of second information lines 413, and the output end of each group of second information lines 413 is respectively connected to a corresponding The electric push assembly 407 is connected, and the first external frame 414 and the second external frame 417 are fixedly installed between the second horizontal plate 409 and the bottom of the two sliding sleeves 404, respectively. The bottom of the first external frame 414 is fixedly installed with a first locking assembly 415, and the interior of the first locking assembly 415 is fixedly installed with a threaded sleeve 416. The bottom of the second external frame 417 is fixedly installed with a second locking assembly 418, and the interior of the second locking assembly 418 is fixedly installed with a first roller bearing 419. A first transmission rod 420 is movably inserted on one side of the inner wall of the assembly chamber 1, and the outer wall of the first transmission rod 420 is fixed.

[0041] The effect achieved by the entire embodiment 1 is as follows: by presetting the above-mentioned components, the mechanism can independently set up a conveying path under the vacuum circuit breaker bracket. When the device is placed on the top of the bracket by a trolley, it can be captured by the relevant distance measuring components and cooperate with some mechanical components to drive the provided plastic insulating rubber pad 408 to complete the position rise. The thrust provided by the mechanical components and the downward pressure provided by the devices are used to force the plastic insulating rubber pad 408 to deform, thereby increasing the coverage area of the plastic insulating rubber pad 408. The material properties of the plastic insulating rubber pad 408 are used to ensure a high friction effect between the plastic insulating rubber pad 408 and the bottom of the device, and complete the soft fixation of the device. Subsequently, through the cooperation of the driving components, the device can be autonomously moved back and forth laterally inside the cabinet. This method can completely replace traditional manual control, so that after the device is placed, the relevant personnel can evacuate quickly, and at the same time, the soft fixation can avoid damage to the device shell.

[0042] Example 2, according to Figure 2 、 Figure 5 、 Figure 7-11 As shown, the second interlocking mechanism 5 includes a whole frame 501, which is fixedly mounted on the rear surface of the inner partition 3, and a group of shells 502 are equidistantly mounted on the outer wall of the whole frame 501, and a first linkage rod 503 is movably inserted inside a group of shells 502, and a group of grounding knives 504 are fixedly sleeved on the outer wall of the first linkage rod 503, and each grounding knife 504 is movably placed in a corresponding shell 502, and a second linkage rod 505 is movably inserted between the assembly warehouse 1 and the high-voltage warehouse 2, and the outer walls of the second linkage rod 505 are respectively fixedly sleeved with a pulling member 506 and an active bevel gear 507, one end of the pulling member 506 is connected to the first linkage rod 503, and a positioning frame 508 is fixedly mounted on the rear surface of the inner partition 3, and a second transmission rod 509 is movably inserted inside the positioning frame 508, and the outer walls of the second transmission rod 509 are respectively fixedly mounted with a driven bevel gear 510 and a driven different gear 511. 507 is meshed with the driven bevel gear 510, the outer surface of an iron track 427 is provided with a self-locking part 512, the outer wall fixed sleeve of the second linkage rod 505 is provided with a reverse thrust sleeve 513, the adaptive drive mechanism 6 includes a protective box 601, the protective box 601 is fixedly installed on one side of the outer wall of the assembly warehouse 1, and a third external frame 602 is fixedly installed on one side of the outer wall of the assembly warehouse 1. A micro reduction box 603 is fixedly installed on the outer surface of the third external frame 602, and a power input end of the micro reduction box 603 is fixedly connected to a servo motor 604, and the shaft end of the micro reduction box 603 is fixedly connected to a driving gear 605. A second cooperative gear 606 is provided inside the protective box 601, and a driven gear 607 is fixedly provided at one end of the outer wall of the first transmission rod 420. The driving gear 605 is respectively meshed with the driven gear 511 and the second cooperative gear 606, and the second cooperative gear 606 is meshed with the driven gear 607.

[0043] The effect achieved by the entire embodiment 2 is as follows: by presetting the above components, the driving member is located between the two functional components. When the device is powered on, the driving member drives the driving gear 605 to rotate counterclockwise. The meshing connection between the driving gear 605, the second cooperating gear 606 and the driven gear 607 can enable the driving crown gear 421 connected to the first transmission rod 420 to obtain power. Since the driving crown gear 421 is meshed with the first cooperating gear 425, the power can directly act on the threaded rod 426, and the surface thread thereof is retracted and rotated. Then, the inverter can be slowly pushed in by the cooperation of the connected components. At the same time, the driving gear 605 and the driven gear 511 are also in meshing connection. The driven gear 511 has only half the number of teeth, and the driving gear 605 cannot continuously transmit power to the driven gear 511. When the two lose contact, the power is lost, and the driven gear 511 can only rely on the initial power to start rotating. Since the connecting parts will continue to increase power loss, the speed of the driven gear 511 will decrease accordingly. In this state, the actual speed of the driven gear 511 is much lower than that of the driven gear 607, which provides waiting time for the inverter to be pushed in, avoiding continuous power input, resulting in structural damage to the connected parts of the driven gear 511. When the driven gear 511 is in contact with the driving gear 605 for transmission, the power will be further transmitted to the second transmission. The driving rod 509 transmits the power, and through the meshing of the active bevel gear 507 and the driven bevel gear 510, the second linkage rod 505 rotates immediately, and the connected pulling member 506 shows a pulling trend, driving the grounding knife 504 on the first linkage rod 503 to rotate and rise, completing the separation from the connected components, so that the equipment is released from the grounding state. When the inverter is fully pushed in, the driven gear 511 also completes a rotation, and some teeth can re-engage with the active gear 605. When the equipment is powered off, the driving member rotates clockwise, and the threads on the threaded rod 426 are in an outward rotation mode. The inverter is pushed out by the connected components, and the pulling member 506 shows a downward pressing trend, driving the grounding knife 504 to reset, completing the separation from the connected components. The components are plugged in, and the two functional components contained in the equipment share a unified drive component and use multiple forms of gears to complete power transmission. According to the different shapes and specifications of the gear parts, not only can the two functional components be linked to each other, but also the movement speeds of the two can be significantly different, ensuring that the cabinet can be quickly disconnected from the ground when it is powered on, and vice versa, it can be quickly closed after power off, and the entry of the vacuum circuit breaker is restricted. This method effectively solves the many disadvantages brought about by traditional manual control, so that the interlocking parts can quickly and independently complete the corresponding adaptive control according to the power-on status of the cabinet, ensuring that the grounding status can be accurately switched when the power is on and off, greatly increasing the control efficiency of the cabinet interlocking parts, and improving the safety of cabinet use.

[0044] Example 3, according to Figure 1 and Figure 10As shown, the signal capture mechanism 7 includes a reinforcing plate 701, which is fixedly mounted on one side of the outer wall of the assembly bin 1. An electrical control box 702 is fixedly mounted on the outer surface of the reinforcing plate 701, and a collection window 703 is provided on the outer surface of the electrical control box 702.

[0045] The effect achieved by the entire embodiment 3 is: by presetting the above-mentioned components, before the cabinet is used, the relevant gesture data can be imported into the relevant modules of the electrical control box 702, mainly including power-on and power-off instructions. When the cabinet is running, the relevant personnel can complete the gestures within the capture range of the acquisition window 703. After analysis and judgment by the system module, the operation of the drive component is controlled, and the power on and off in the cabinet are quickly executed by each interlocking component. This method, using the operation mode that combines signal acquisition and mechanical linkage, can maximize the guarantee that the relevant personnel evacuate to the periphery of the cabinet, avoid direct or indirect contact with the cabinet, and greatly reduce the risk of electric shock to the human body.

[0046] The working principle of the entire device is as follows: in the preparation stage, the main body of the device is first moved to the designated work area, and the bottom of the combined base plate 11 is fully in contact with the ground. The wiring harnesses in the high-voltage chamber 2 are accurately installed. Then, the external plug is connected to the socket 9. After being transmitted through the conductive component 10, the independent power supply 8 completes the energy distribution to provide energy for the electrical components contained in each mechanism. The vacuum circuit breaker is transferred using an adapter trolley and finally placed inside the assembly chamber 1, with the bottom of the device fully placed between the two iron rails 427.

[0047] During the power-on phase, after the circuit breaker enters the assembly compartment 1, in the initial state, it can partially cover the top of the load-bearing bracket 401, resulting in the rangefinder 410 being blocked from view and the measured value changing rapidly. When the real-time value stabilizes, the signal is quickly fed back to the linkage controller 411 via the first information line 412, and the linkage controller 411 then controls the opening of each T-shaped slide 405 through the second information line 413, slowly driving the two plastic insulating rubber pads 408 to rise. Subsequently, the plastic insulating rubber pads 408 gradually contact the bottom of the circuit breaker, and the thrust exerted by the T-shaped slide 405 and the weight of the circuit breaker are used to generate the pressure. The downward pressure forces the plastic insulating rubber pad 408 material to deform, and eventually covers a large area to the bottom of the circuit breaker. The relevant personnel can be located outside the assembly warehouse 1 and make a power-on gesture to the electrical control box 702 within the specified range. The acquisition window 703 quickly captures the gesture and quickly feeds it back to the relevant module to complete the analysis and determine the command signal. The servo motor 604 is randomly controlled to start. After being processed by the micro reduction box 603, the low-speed and high-torque power is directly transmitted to the driving gear 605, driving it to rotate clockwise, and then the second cooperative gear 606, the driven gear 607 and the driven gear 511 complete the process. One-step transmission, the first part, after the driven gear 607 rotates, it is transmitted to the lower level by the first transmission rod 420. By utilizing the meshing connection between the cross bar 423 and the driven crown gear 424 and the first cooperating gear 425, the physical properties of the second roller bearing 422, the rotation connection between the threaded sleeve 416 and the threaded rod 426, the physical properties of the first roller bearing 419 and the movable connection between the sleeve 404 and the T-shaped slide 405, the circuit breaker is driven to move horizontally above the iron track 427 and continuously move toward the ports provided in the inner partition 3 until the circuit breaker connector is completely inserted into each port. The second part, using the active bevel gear 507 The meshing connection between the housing 502 and the driven bevel gear 510 transmits power to the second linkage rod 505 and the pulling member 506 respectively. The former rotates freely, gradually driving the reverse thrust sleeve 513 to disengage the self-locking member 512, ensuring that the circuit breaker is not restricted by the structure when moving. The latter completes the further transmission of power, and utilizes the movable connection between the housing 502 and the grounding knife 504 to drive each grounding knife 504 to slowly rise and gradually disengage from the connected components. Because the circuit breaker has a long travel path, the driven gear 511 adopts a half-tooth design to achieve the purpose of delayed power output, ensuring that the circuit breaker and the grounding knife 504 can be controlled simultaneously to avoid structural constraints.

[0048] During the power-off phase, the signal is captured first through the above method, and the driving gear 605 is driven counterclockwise. When the circuit breaker is pulled back, the grounding knife 504 begins to slowly descend. After the circuit breaker is reset for a certain distance, the reverse thrust sleeve 513 is pressed onto the self-locking member 512 again, and a limit body can be formed above the load-bearing bracket 401 to prevent the circuit breaker from entering. After the circuit breaker is completely disengaged, each grounding knife 504 is inserted into the initial assembly again.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
