Description

Technical Field

[0001] This invention relates to the field of switchgear, and in particular to an intelligent high and low voltage switchgear. Background Technology

[0002] Currently, withdrawable switchgear cabinets are clearly divided internally into functional unit compartments, busbar compartments, and cable compartments by vertical partitions, with each area isolated to ensure safety. Drawer units are mounted in the functional unit compartments via guide rails, and their internal electrical components are connected to external power supplies through a cable compartment located within the cabinet. This connection is achieved via fixed cable connectors or standardized plug-in components. To facilitate drawer removal for maintenance, primary power cables have a pre-installed buffer arc of a specific length in the cable compartment and are secured using cable management channels. Secondary control circuits generally employ a plug-in method where a static plug fixed to the rear panel of the cable compartment mates with a moving plug in the drawer, achieving uninterrupted power disconnection during testing. However, existing withdrawable switchgear technologies still have certain shortcomings: When dealing with or maintaining core electrical components such as the busbars inside the drawers, operators must first move to the back of the cabinet, open the rear cabinet door, manually disconnect the power cable from the drawer and the external equipment, and then move to the front of the cabinet to fully pull out the drawer before the component can be removed for inspection. The installation process after repair requires repeating this process in reverse. This forces the two critical steps of operating the drawer at the front and plugging and unplugging cables at the back to be separated in space and time, requiring operators to move back and forth between the front and back of the cabinet and work alternately. This process not only significantly increases maintenance time and workload, but also increases the probability of forgetting to restore wiring due to the numerous steps. Furthermore, if personnel at the front misoperate while operating at the back of the cabinet, it may also cause safety risks. Summary of the Invention

[0003] In view of the problems of low efficiency and safety risks in the above-mentioned or existing technologies, which require operators to move back and forth between the front and back of the cabinet and perform alternating operations, this invention is proposed.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1 , Figure 2 and Figure 3This embodiment provides an intelligent high and low voltage switchgear that eliminates the need for operators to move back and forth between the front and back of the cabinet. It includes a cabinet body 1 and a support frame 2 fixedly installed within the cabinet body 1, with a mounting bracket 5 fixedly installed on the support frame 2; several drawers 3 slidably installed on the support frame 2, each drawer 3 module having a connector module 4; a locking module 6 installed on each drawer 3, the locking module 6 including a locking component 61 and a traction component 63 for triggering the locking component 61; a clamping component 62 and a pressing component 64 for triggering the clamping component 62; and a control component 65. The control component 65 is used to drive the traction component 63 to trigger the locking component 61 to lock the connector module 4 when the drawer 3 is closed, and to drive the traction component 63 to trigger the locking component 61 to unlock the connector module 4 when the drawer 3 is open for maintenance, simultaneously driving the pressing component 64 to trigger the clamping component 62 to clamp the connector module 4.

[0030] It should be noted that the support frame 2 is a welded steel structure frame, which is welded together from columns, beams, etc., and is used to bear the sliding load of the drawer 3, etc.; the terminal module 4 consists of a moving contact and a stationary contact, and the moving contact and the stationary contact have matching locking holes. The moving contact is set on the drawer 3 and connected to the busbar, circuit breaker and other components inside the drawer 3. The stationary contact is connected to the branch busbar or cable terminal block of the cabinet 1, and the high current transmission is realized after docking. The specific structure of the support frame 2, drawer 3, terminal module 4 and other components inside the cabinet 1 are all existing technologies, so they will not be described in detail in this application.

[0031] The locking module 6 addresses the fragmented operation mode of existing pull-out switchgear, where the front drawer 3 is pulled out and cables are disconnected at the rear. Through the linkage design of the control component 65, it integrates two functions: locking the moving and stationary contacts in the working state and unlocking and clamping the stationary contacts in the maintenance state. This enables intelligent switching between the working and maintenance states of drawer 3: when drawer 3 is closed, it automatically locks the moving and stationary contacts to ensure the stability and conductivity of the circuit connection; when drawer 3 is opened for maintenance, it automatically unlocks the moving and stationary contacts and simultaneously clamps and positions the stationary contact. This allows for separation of the moving and stationary contacts while facilitating their reconnection when the operator pushes drawer 3 back in after maintenance. The operator only needs to complete a single operation at the front of the cabinet, eliminating the need to travel back and forth to the rear to plug and unplug the wiring module 4. This simplifies the maintenance process, shortens operation time, reduces the risk of misoperation due to complicated procedures such as forgetting wiring, and avoids safety hazards caused by accidental activation by personnel at the front when operating from the rear of the cabinet.

[0032] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6The locking assembly 61 includes a mounting plate 611 fixedly installed on the outside of the drawer 3. A plurality of fixing cylinders 612 are fixedly installed on the mounting plate 611. A locking pin 613 slides through the fixing cylinder 612. A circular plate 614 is fixedly installed on the outside of the locking pin 613 and is slidably connected to the inner wall of the fixing cylinder 612. A return spring 615 is installed between the circular plate 614 and the mounting plate 611. The return spring 615 is sleeved on the outside of the locking pin 613. A connecting plate 616 is installed on the end of the plurality of locking pins 613 away from the mounting plate 611.

[0033] It should be noted that the locking assembly 61 achieves rigid locking of the connector module 4 when the switch cabinet is in operation, ensuring the reliability of the circuit connection and vibration resistance when the drawer 3 is working; the fixing cylinder 612 provides installation and guidance for the locking pin 613, preventing the locking pin 613 from deflecting during movement; the circular plate 614 is fixedly connected to the locking pin 613 to transmit the elastic force of the return spring 615, and the outer diameter of the circular plate 614 is clearance-fitted with the inner wall of the fixing cylinder 612, which ensures smooth sliding and prevents the locking pin 613 from radially wobbling; the return spring 615 is in a natural extension and contraction state under normal conditions, and its elastic force is transmitted through the circular plate 61... 4. Push the locking pin 613 to extend towards the connector module 4 and insert it into the preset locking hole of the connector module 4 to achieve mechanical locking between the connector and the mounting bracket 5, and avoid poor contact of the connector due to vibration when the drawer 3 is working; the connecting plate 616 connects multiple locking pins 613 in series to ensure that all locking pins 613 move in unison and avoid local locking failure caused by jamming of a single locking pin 613; when unlocking is required, the connecting plate 616 is pulled by the traction component 63, which drives all locking pins 613 to compress the return spring 615 and return to the fixed cylinder 612, releasing the mechanical locking constraint on the connector module 4.

[0034] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 The traction assembly 63 includes a telescopic rod frame 631 fixedly installed on the mounting plate 611. A spring telescopic rod 632 is fixedly installed on the telescopic rod frame 631. A wedge block 633 is fixedly installed at the telescopic end of the spring telescopic rod 632. A second wedge block 634 that cooperates with the first wedge block 633 is fixedly installed on the side of the connecting plate 616 near the spring telescopic rod 632.

[0035] It should be noted that the traction component 63 enables the switching between locking and unlocking; the telescopic rod frame 631 is made of high-strength aluminum alloy, providing stable support for the spring telescopic rod 632 while reducing the overall weight; the spring telescopic rod 632 is in a naturally extended state under normal conditions, pushing wedge block 1 633 away from wedge block 2 634. At this time, wedge block 1 633 and wedge block 2 634 remain separated, and the preload of the locking component 61 is entirely provided by the return spring 1 615. Under normal conditions, the return spring 1 615 pulls the locking pin 613 through the circular plate 614. Connector module 4 is inserted; when control component 65 pulls traction rope 636, traction rope 636 overcomes the elastic force of spring telescopic rod 632 and drives wedge block one 633 to move closer to wedge block two 634, so that the inclined surfaces of the two are tightly fitted. Using the wedge fit, all locking pins 613 are pulled synchronously through connecting plate 616 to retract and compress reset spring one 615, thereby unlocking connector module 4; when control component 65 resets, the rebound force of spring telescopic rod 632 quickly pushes wedge block one 633 away from wedge block two 634, returning to the separated state. The elastic force of reset spring one 615 pushes locking pin 613 out again, completing the locking action. The whole process does not require manual intervention.

[0036] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 The control component 65 includes a sliding bracket 651 that is slidably mounted on the side wall of the drawer 3; A fixed pulley 635 is fixedly installed on the outside of the drawer 3. A traction rope 636 is wound around the outside of the fixed pulley 635. The two ends of the traction rope 636 are fixedly connected to the sliding frame 651 and the wedge block 633, respectively.

[0037] It should be noted that the return spring 653 is in a naturally extended state under normal conditions, applying a reverse pulling force to the sliding frame 651 to maintain the initial position of the sliding frame 651. At this time, the locking component 61 is locked and the clamping component 62 is released. The fixed pulley 635 is connected to the bracket on the outside of the drawer 3 through a bearing. When the sliding frame 651 moves towards the pressing component 64, the traction rope 636 changes the direction of force through the fixed pulley 635, and simultaneously pulls the wedge block 633 to compress the spring telescopic rod 632, thereby unlocking the locking component 61. Conversely, when the sliding frame 651 is reset under the action of the return spring 653, the rebound force of the spring telescopic rod 632 pulls the wedge block 633 back to its initial position, and the traction rope 636 simultaneously drives the sliding frame 651 to reset.

[0038] Reference Figure 4 , Figure 5 , Figure 8 and Figure 9 The control component 65 further includes a side plate 652 fixedly installed on the side wall of the drawer 3, and a plurality of return springs 653 fixedly installed between the side plate 652 and the sliding frame 651; a control plate 655 is fixedly installed on the side wall of the drawer 3, and a control groove 656 is provided on the control plate 655; a control rod 654 slidably connected to the control groove 656 is fixedly installed on the sliding frame 651.

[0039] Reference Figure 9 and Figure 10 The control slot 656 is composed of a trigger slot 6561 and a reset slot 6562 that are connected to each other.

[0040] It should be noted that (the principle of the control groove 656 is similar to the pressing and resetting structure of a ballpoint pen), both the connection between the trigger groove 6561 and the reset groove 6562 are equipped with a check groove. When the operator pulls the sliding frame 651, the control rod 654 slides along the trigger groove 6561, causing the sliding frame 651 to compress the reset spring 653 and move, simultaneously triggering the unlocking and locking assembly 61 and the clamping of the stationary contact. When the control rod 654 slides to the end of the trigger groove 6561, the control rod 654 is fixed, and the sliding frame 651 remains in this state, realizing the mechanical locking of the sliding frame 651. At this time, the operator can safely pull out the drawer 3 for maintenance without continuously pressing the control rod 654, freeing their hands. After maintenance is completed, the drawer 3 is pushed in, and the sliding frame 651 is pulled again, causing the control rod 654 to slide along the reset groove 6562. The elastic force of the reset spring 653 pushes the sliding frame 651 to reset, and the control rod 654 returns to the initial position along the trigger groove 6561.

[0041] In practical use, when the intelligent high and low voltage switchgear in the factory workshop is powered normally, each drawer 3 is closed in the working position of the cabinet 1, and is in a stable operating state; at this time, the control component 65 maintains the initial standby posture, and the control lever 654 is engaged in the initial end of the trigger slot 6561 of the control slot 656 (e.g., Figure 10As shown (that is, the direction closest to the connector module 4), the return spring 653 maintains the sliding frame 651 in the initial position away from the compression assembly 64. In the traction assembly 63, the wedge block 633 and the wedge block 634 are separated. The return spring 615 of the locking assembly 61 drives the locking pin 613 to extend through the circular plate 614 and insert into the locking hole of the connector module 4, realizing the rigid locking of the moving and stationary contacts. Even if the workshop equipment vibrates during operation, the circuit connection can be ensured to be stable. When a branch circuit fails and needs to be repaired, the operator does not need to go back and forth to the back of the cabinet. He only pulls the sliding frame 651 in front of the cabinet, so that the control rod 654 slides along the trigger groove 6561 away from the stationary contact, causing the sliding frame 651 to move against the force of the return spring 653. The guide rope 636 changes the direction of force through the fixed pulley 635, pulling the first wedge block 633 close to and against the second wedge block 634. With the force transmission effect of the wedge engagement, the connecting plate 616 is pulled, causing all locking pins 613 to retract synchronously into the fixed cylinder 612, unlocking the connector module 4. At the same time, the sliding frame 651 drives the pressing component 64 to trigger the clamping component 62, completing the fixed positioning of the separated stationary contact. After the control rod 654 slides to the end of the trigger groove 6561 and enters the reset groove 6562, the operator releases the rod. The reset spring 653 drives the sliding frame 651 to move a short distance. At the same time, the control rod 654 slides to the recess of the reset groove 6562. Then the sliding frame 651 remains in its current state, and the operator can directly pull out the drawer 3 for internal component maintenance.

[0042] After maintenance, the operator smoothly pushes drawer 3 into cabinet 1 along support frame 2. Because the stationary contact is fixed by clamping component 62, the moving and stationary contacts can be precisely connected. Then, the control lever 654 is pulled again to disengage it from sliding along reset groove 6562 and slide back to reset along the lower half of reset groove 6562. Then, reset spring 3 653 quickly releases its stored energy, pushing sliding frame 651 back to its initial position. Traction rope 636 loosens accordingly, and spring extension rod 632 pushes wedge block 1 633 away from wedge block 2 634, returning to the separated state. At the same time, reset spring 1 615 pushes the locking mechanism. Pin 613 extends again and inserts into the locking hole of connector module 4, completing the rigid locking of the moving and stationary contacts. Control rod 654 finally retracts to the initial end of trigger slot 6561, and drawer 3 resumes normal power supply function. The entire process realizes intelligent switching between locking in working state and unlocking clamping in maintenance state through the linkage design of control component 65. It breaks the existing fragmented operation mode of operating drawer 3 at the front of the switch cabinet and disconnecting cables at the back of the cabinet. It simplifies the maintenance process, shortens the operation time, and avoids the safety hazards of operating at the back of the cabinet. It is fully adapted to the actual needs of the factory for rapid emergency repair and stable power supply.

[0043] Reference Figure 4 , Figure 8 and Figure 9The support frame 2 is fixedly mounted with several mounting brackets 5. Each mounting bracket 5 has an opening for accommodating the connector module 4. The clamping assembly 62 includes a fixing plate 621 fixedly mounted on the side of the mounting bracket 5 away from the drawer 3. A second return spring 622 is fixedly mounted on the side of the fixing plate 621 near the connector module 4. A clamping plate 623 is fixedly mounted at the end of the second return spring 622. An abutment block 624 is fixedly mounted on the mounting bracket 5. A sliding rod 625 that slides through the fixing plate 621 is fixedly mounted on the side of the clamping plate 623 near the fixing plate 621.

[0044] It should be noted that after the connector module 4 is unlocked, the clamping component 62 provides clamping positioning for the stationary contact of the connector module 4, avoiding misalignment of the connector during secondary installation; the opening size of the mounting bracket 5 is compatible with the external dimensional tolerance of the connector module 4, ensuring that the connector module 4 is accurately embedded and providing basic positioning for clamping; the abutment block 624 is made of rubber; the second return spring 622 is in a naturally extended state under normal conditions, at which time there is a gap between the clamping plate 623 and the connector module 4; the inner side of the clamping plate 623 is pasted with an anti-slip insulating rubber pad to increase the friction with the stationary contact and improve clamping stability; when the slide rod 625 is pushed by the squeezing component 64, it causes the clamping plate 623 to compress the second return spring 622 and move towards the connector module 4 until the clamping plate 623 is tightly fitted with the stationary contact to achieve clamping and fix the stationary contact.

[0045] Reference Figure 4 , Figure 8 and Figure 9 The extrusion assembly 64 includes a wedge block 3 641 fixedly installed on the sliding frame 651, and a wedge block 4 642 that cooperates with the wedge block 3 641 is fixedly installed at the end of the slide rod 625.

[0046] It should be noted that when the sliding frame 651 moves towards the sliding rod 625, the inclined surfaces of wedge block three 641 and wedge block four 642 press against each other, generating a thrust along the axial direction of the sliding rod 625, which pushes the sliding rod 625 to move the clamping plate 623 towards the terminal module 4, thereby clamping the stationary contact. When the sliding frame 651 resets, wedge block three 641 and wedge block four 642 separate, and the elastic force of the reset spring two 622 causes the sliding rod 625 and wedge block four 642 to move in the opposite direction, and the clamping plate 623 releases the stationary contact. The entire action process is synchronized with the unlocking and locking actions of the locking assembly 61.

[0047] In practical use, when the control component 65 drives the sliding frame 651 to move away from the stationary contact, it will simultaneously trigger the action of the pressing component 64. The wedge block 3 641 on the sliding frame 651 moves with the sliding frame 651 and presses against the inclined surface of the wedge block 4 642 at the end of the slide rod 625. The axial thrust is generated by the force transmission effect of the inclined surface, which pushes the slide rod 625 to slide smoothly along the through hole of the fixed plate 621, thereby driving the clamping plate 623 to move towards the stationary contact and stretching the return spring 2 622 to store energy. The anti-slip insulating rubber pad on the inner side of the clamping plate 623 is tightly attached to the stationary contact, firmly clamping the stationary contact. At the same time, the abutment block 624 cooperates to limit the movement, ensuring that the stationary contact always maintains the initial installation position during maintenance, avoiding subsequent docking deviations due to displacement.

[0048] After maintenance, the operator can directly push drawer 3 into cabinet 1 to complete the connection of the moving and stationary contacts. Then, driven by the reset action of control component 65, sliding frame 651 retracts to its initial position, and pressing component 64 simultaneously releases the drive of clamping component 62. When sliding frame 651 moves, wedge block three 641 moves away from wedge block four 642, and the inclined surface contact between the two is released, no longer generating axial thrust. At this time, reset spring two 622 releases the previously stored energy, driving clamping plate 623 to move away from stationary contact, and sliding rod 625 simultaneously retracts to its initial position. Clamping plate 623 separates from stationary contact, and clamping state is released. The entire clamping and releasing process is completely synchronized with the unlocking and locking action of locking component 61, ensuring that stationary contact is stably fixed during maintenance and that circuit restoration is not affected during reset.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
