Description

Technical Field

[0001] This application relates to the technical field of power equipment, and in particular to a solid-state cabinet. Background Technology

[0002] Solid-state switchgear, in the power industry, typically refers to solid-insulated ring main units (RMS). These RMS units use solid insulating materials as the primary insulating medium. They encapsulate one or more modules—including the vacuum interrupter and its conductive connections, disconnecting switches, grounding switches, main busbars, and branch busbars—with solid insulating media. These modules are fully insulated and sealed, and can be recombined or expanded. The accessible surfaces of these modules are coated with a conductive or semi-conductive shielding layer and can be directly and reliably grounded. Compared to gas-insulated switchgear, it offers gas insulation, requires no maintenance, and is more environmentally friendly. Existing solid-state control cabinets are typically divided vertically into three sections: a low-voltage control compartment at the top with multiple instrument switches and displays, a circuit breaker compartment in the middle, and a cable compartment at the bottom. The circuit breakers are usually directly fixed to the cabinet casing. When the circuit breakers need to be removed, replaced, or repaired, the entire solid-state control cabinet must be dismantled, which is time-consuming and labor-intensive.

[0003] Therefore, there is an urgent need for a solid-state cabinet that allows staff to easily disassemble, replace, or repair circuit breakers. Summary of the Invention

[0004] This application provides a solid-state cabinet that facilitates the disassembly, replacement, or maintenance of circuit breakers by staff, reducing operational difficulty and complexity, and improving operational efficiency.

[0005] This application provides a solid-state cabinet, which adopts the following technical solution: A solid-state enclosure includes a housing, a circuit breaker, a controller, and a quick-connect plug; The housing includes a main body, several front cover plates, and several rear cover plates; the main body has an internal cavity and a horizontally arranged support plate for supporting the circuit breaker, and the cavity forms a front opening and a rear opening on both sides of the main body; the front cover plates and the rear cover plates are detachably connected to the main body, the several front cover plates are used to seal the front opening, and the several rear cover plates are used to seal the rear opening; The circuit breaker is detachably connected to the support plate by a plurality of screws. The front opening provides operating space for the plurality of screws, and the rear opening is used for the circuit breaker to enter and exit the cavity. Both the controller and the quick-connect plug are disposed in the cavity, with the controller located above the circuit breaker and the quick-connect plug located below the controller; the controller is electrically connected to the quick-connect plug, and the quick-connect plug is used for detachable circuit connection of the circuit breaker.

[0006] By adopting the above technical solution, when the circuit breaker needs to be removed, the staff first removes the front and rear covers, then disconnects the circuit through the front and rear openings. After disconnecting the circuit breaker from the support plate through the front opening, the circuit breaker can be pulled out from the rear opening and placed on a transfer cart. Similarly, the circuit breaker can be sent into the cavity through the rear opening using a transfer cart to complete the installation. This solid-state cabinet facilitates the disassembly, replacement, or maintenance of circuit breakers by the staff, reducing the difficulty and complexity of operation and improving operational efficiency.

[0007] Optionally, it also includes an auxiliary device for assisting the circuit breaker in and out of the cavity, and the bottom of the circuit breaker has a base for contacting the support plate and forming a detachable connection; The auxiliary device is disposed on the support plate and includes two auxiliary components, which are respectively located on both sides of the base; The auxiliary component includes a base, multiple wheels, and multiple elastic elements; The wheel is used to contact the base and rotates about a vertical axis relative to the base; the elastic element is disposed between the base and the wheel and is used to drive the wheel to move horizontally toward the base.

[0008] By adopting the above technical solution, multiple wheels can reduce the friction between the base and the inner walls of the main body on both sides when the operator pulls the circuit breaker, thus facilitating the circuit breaker to enter and exit the cavity along the support plate; at the same time, multiple elastic elements can drive the circuit breaker to be centered after entering the cavity, making it convenient for the circuit breaker to be accurately positioned in the cavity and then connected to the support plate by multiple bolts.

[0009] Optionally, the bottom of the base near the wheel has an inclined drag-increasing surface, and the top of the wheel has a contact surface for contacting and abutting the drag-increasing surface, and the contact surface tapers upward.

[0010] By adopting the above technical solution, the contact effect between the wheel and the base can be improved, thereby making it easier for operators to control the circuit breaker to pull and move by rotating multiple wheels. At the same time, the force applied to the base by multiple elastic elements through the wheels can not only drive the circuit breaker to be centered in the cavity for accurate positioning, but also apply an upward force to the circuit breaker, reducing the friction between the circuit breaker and the support plate, further facilitating the operator to control the circuit breaker to pull and move.

[0011] Optionally, the auxiliary components may further include a base and an adjustment element; The base and the seat are movably connected in the horizontal direction, and the multiple wheels are rotatably connected to the base. The adjusting member is disposed on the base and is used to control the multiple wheels to rotate synchronously and in the same direction.

[0012] By adopting the above technical solution, it is possible for staff to control the movement of the circuit breaker by simultaneously controlling the rotation of multiple wheels through the adjustment components. This reduces the difficulty and effort required for staff to control the movement of the circuit breaker, and also effectively reduces the probability of damage to other structures due to friction during the movement of the circuit breaker.

[0013] Optionally, the auxiliary device may further include a baffle; The baffle is connected to the two seats at both ends and is used to contact the base to limit the circuit breaker; after the circuit breaker is connected to the support plate, the baffle is located on the side of the base near the front opening.

[0014] By adopting the above technical solution, the baffle can assist the circuit breaker in positioning relative to the auxiliary device, thereby facilitating the operation of the circuit breaker in the cavity by the help of the auxiliary device; at the same time, the baffle can make the two auxiliary components form a whole, improving the overall structural strength of the auxiliary device.

[0015] Optionally, the auxiliary device may further include a control component; The control element is located on one side of the baffle and is used to control the synchronous rotation of the two adjusting elements.

[0016] By adopting the above technical solution, it is possible for staff to control the rotation of multiple wheels on both sides of the base simultaneously, thereby further reducing the difficulty of operation and improving the effect of moving the circuit breaker with the help of auxiliary devices.

[0017] Optionally, the seat is movably connected to the support plate, and the auxiliary device further includes an operating component; The direction of movement of the base is parallel to the direction of the circuit breaker entering and exiting the cavity, and the operating element is disposed on the support plate and is used to drive the base to move.

[0018] By adopting the above technical solution, it is convenient for staff to move the circuit breaker by moving the seat and rotating the wheels. The circuit breaker moves quickly in the cavity and slows down at the rear opening, making it easy for staff to gradually transfer the circuit breaker to the transport vehicle or place it on the auxiliary device.

[0019] Optionally, when the operating element drives the seat to move to its limit position away from the front opening, the seat portion extends out of the cavity.

[0020] By adopting the above technical solution, it is possible to further facilitate the staff to gradually transfer the circuit breaker to the transport vehicle or to gradually place the circuit breaker on the auxiliary device.

[0021] Optionally, one end of the operating member extends out and is located on the side of the main body away from the front opening. When the operating member drives the seat to move to its limit position away from the front opening, the portion of the seat extending out of the cavity forms a protective layer above the operating member.

[0022] By adopting the above technical solution, the probability of interference caused by the protruding end of the operating component when the operator gradually transfers the circuit breaker to the transport vehicle or places the circuit breaker on the auxiliary device can be effectively reduced, and the operating component can be effectively protected from impact damage.

[0023] Optionally, the auxiliary component may also include a movable plate; The movable plate is movably connected to the base, and its direction of movement is parallel to the direction of movement of the base. The two ends of the elastic member are respectively connected to the movable plate and the base, and the elastic member is used to drive the movable plate and the base to move in opposite directions. Both sides of the main body have guide surfaces for contacting the movable plate, and the distance between the two guide surfaces near the rear opening is smaller than the distance between the two guide surfaces near the front opening; as the operating member drives the seat to move away from the front opening to its limit position, multiple elastic members drive the base to gradually separate from the support plate through multiple wheels.

[0024] By adopting the above technical solution, the magnitude of the elastic force of the elastic element changes during the movement of the seat, thereby reducing the friction between the circuit breaker and the support plate as the circuit breaker leaves the cavity from the rear opening, and increasing the friction between the circuit breaker and the support plate as the circuit breaker enters the cavity from the rear opening. This facilitates the movement and removal of the circuit breaker while improving the positional stability of the circuit breaker after it is moved and inserted.

[0025] In summary, this application includes at least one of the following beneficial effects: 1. A solid-state cabinet that allows staff to easily disassemble, replace, or repair circuit breakers, reducing operational difficulty and complexity and improving operational efficiency; 2. It allows staff to easily move the circuit breaker in and out of the cavity, saving time and effort, and also facilitates the transfer of the circuit breaker between the cavity and the transport vehicle; 3. It can effectively reduce the negative impact of friction between the circuit breaker and other structures on its movement, and at the same time facilitate the accurate positioning of the circuit breaker for subsequent installation and fixation.

[0028] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail. Example 1

[0029] Reference Figure 1 and Figure 2 This application discloses a solid-state cabinet, including a housing 1, a circuit breaker 2, a controller 3, and a quick-connect plug 4.

[0030] Reference Figure 2 and Figure 3 The housing 1 includes a main body 11, several front cover plates 13 and several rear cover plates 14.

[0031] The main body 11 has a hollow cuboid structure, and its interior has a cavity 111 for installing the circuit breaker 2, controller 3 and quick connector 4. The cavity 111 has a front opening 112 and a rear opening 113 at its two ends along its length. A support plate 12 for supporting the circuit breaker 2 is horizontally installed inside the main body 11, and the support plate 12 is located in the lower middle position of the cavity 111. The front cover plate 13 and the rear cover plate 14 are both rectangular plate structures. The front cover plate 13 and the rear cover plate 14 are detachably connected to the main body 11. Several front cover plates 13 are used to seal the front opening 112 and several rear cover plates 14 are used to seal the rear opening 113. In this embodiment, the preferred housing 1 includes two front cover plates 13 and two rear cover plates 14, and both the front cover plates 13 and the rear cover plates 14 are detachably connected to the main body 11 by multiple screws 5. In practical applications, the interior of the main body 11 can be detachably installed with structures that provide connection positions for the front cover plates 13 and the rear cover plates 14 at positions near the front opening 112 and near the rear opening 113. Preferably, the circuit breaker 2 enters and exits the cavity 111 by a transfer vehicle that moves to the side of the rear opening 113. Since the structures that provide connection positions for the front cover plates 13 and the rear cover plates 14 and the transfer vehicles that have the above functions are common existing technologies, they will not be described in detail here, and they are only briefly shown in the accompanying drawings.

[0032] Reference Figure 2 and Figure 4 The circuit breaker 2 enters the cavity 111 through the rear opening 113. After being positioned above the support plate 12 near the front opening 112, it is detachably connected to the support plate 12 by multiple screws 5. After the circuit breaker 2 is fixedly connected to the support plate 12 by multiple screws 5, the operator can remove and install the multiple screws 5 through the front opening 112. In this embodiment, since the circuit breaker 2 is prior art in the field, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0033] Reference Figure 2 and Figure 3 The controller 3 is used to control the overall functions of the solid-state cabinet. It is fixedly installed inside the main body 11 and located at the top of the cavity 111 near the front opening 112. After the circuit breaker 2 is installed inside the housing 1, the controller 3 will be located above the circuit breaker 2. In this embodiment, since the controller 3 with the above functions is prior art in the field, it will not be described in detail here, and it is only briefly shown in the accompanying drawings.

[0034] The quick-connect plug 4 is fixedly installed inside the main body 11, located below the controller 3 and near the front opening 112 of the cavity 111. After the circuit breaker 2 is installed inside the housing 1, the quick-connect plug 4 will be located above the circuit breaker 2. The controller 3 is electrically connected to the quick-connect plug 4, which allows for a detachable electrical connection between the circuit breaker 2 and the controller 3. In this embodiment, the quick-connect plug 4 is preferably a secondary aviation plug; since secondary aviation plugs are existing technology in the field, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0035] After the circuit breaker 2 is installed inside the housing 1, the space in the cavity 111 located below the support plate 12 and near the front opening 112 will form a space for the line to enter and connect with the circuit breaker 2, and the space at the top of the cavity 111 located on the side of the controller 3 near the rear opening 113 will form a space for the line to extend from the circuit breaker 2.

[0036] The implementation principle of a solid-state cabinet in this application embodiment is as follows: When it is necessary to remove, repair or replace the circuit breaker 2, first remove several front cover plates 13 and several rear cover plates 14, then disconnect the outgoing and incoming lines of the circuit breaker 2, then disconnect the circuit connection between the circuit breaker 2 and the quick connector 4 at the front opening 112, and then remove several screws 5. At this time, the circuit breaker 2 is in a pull-out and movable state. After that, move the transfer cart to the rear opening 113 side of the housing 1, and you can control the circuit breaker 2 to move along the support plate 12 through the rear opening 113 and place it on the transfer cart. The repaired circuit breaker 2 or the new circuit breaker 2 is also moved to the rear opening 113 side of the housing 1 by a transfer vehicle. After the circuit breaker 2 is moved into the cavity 111 through the rear opening 113, it is placed on the support plate 12. The circuit breaker 2 is then moved along the support plate 12 towards the front opening 112 until it is in the correct position for installation by multiple screws 5. After the circuit breaker 2 is installed and positioned by multiple screws 5, the solid cabinet can be installed in the same way as the previous removal operation. Example 2

[0037] Reference Figure 5 and Figure 6 The difference between this embodiment and Embodiment 1 is that the solid-state cabinet also includes an auxiliary device 6 for assisting operators in controlling the movement of the circuit breaker 2. In this embodiment, the circuit breaker 2 and the support plate 12 are only briefly shown in the accompanying drawings.

[0038] Reference Figure 6 and Figure 7 The auxiliary device 6 is mounted on the support plate 12 and includes two auxiliary components 61, a baffle 62, a control component 63 and an operating component 64; the bottom of the circuit breaker 2 has a base 21, and the auxiliary device 6 controls the movement of the circuit breaker 2 by applying a force to the base 21.

[0039] Reference Figure 7 and Figure 8 The auxiliary component 61 includes a seat 611, a base 612, multiple wheels 613, multiple elastic elements 614, an adjusting element 615, and a movable plate 616.

[0040] The base 611 has a rectangular parallelepiped structure and is movably mounted on the support plate 12. Its direction of movement is parallel to its own length and parallel to the length of the support plate 12. The two bases 611 are respectively mounted on both sides of the top width of the support plate 12, and after the circuit breaker 2 is installed, the base 21 will be located between the two bases 611. The movement of the base 611 relative to the support plate 12 is restricted. When the base 611 moves to the limit position towards the end closer to the front opening 112, the base 611 is completely located in the cavity 111. When the base 611 moves to the limit position towards the end away from the front opening 112, the end of the base 611 away from the front opening 112 will extend out of the rear opening 113.

[0041] The base 612 is also generally rectangular in shape, and is movably connected to the seat 611. Its direction of movement is parallel to its own width and the width direction of the seat 611, and it can move in and out of the seat 611 to the side near the other seat 611 during its movement. The wheel 613 is generally cylindrical in shape, and is rotatably mounted on the side of the base 612 near the other seat 611. Its axis of rotation is vertical, and multiple wheels 613 are evenly distributed on the base 612 along its length. Part of the wheel 613 is located inside the base 612, and part is located on the side of the base 612 near the other seat 611. The part of the wheel 613 outside the base 612 is used to contact the base 21. In this embodiment, preferably, during the movement of the base 612 relative to the seat 611, multiple wheels 613 can be exposed on the side of the seat 611 near the other seat 611.

[0042] The movable plate 616 has a rectangular plate-like structure. It is movably connected to the base 611 and located on the side of the corresponding base 612 away from the other base 612. Its direction of movement is parallel to its own thickness direction and parallel to the direction of movement of the corresponding base 612. During its movement, it can enter and exit the interior of the base 611. The elastic element 614 is installed inside the base 611, with its two ends fixedly connected to the movable plate 616 and the corresponding base 612, respectively. It is used to drive the movable plate 616 and the corresponding base 612 to move away from each other to their extreme positions. In this embodiment, the elastic element 614 is preferably a compression spring, which can drive the movable plate 616 to move away from the corresponding base 612 to its extreme position and the base 612 to move away from the corresponding movable plate 616 to its extreme position. Since compression springs are common prior art, they will not be described in detail here, and only a brief representation is given in the accompanying drawings.

[0043] The adjusting member 615 is used to synchronously drive multiple wheels 613 to rotate relative to the base 612. It has a cylindrical structure and is rotatably mounted on the base 612. Its rotation axis coincides with its own axis and is parallel to the length direction of the base 612. In this embodiment, the adjusting member 615 is preferably a worm gear, with each of the multiple wheels 613 having a worm wheel structure at its top. The adjusting member 615 simultaneously forms a worm gear engagement with the multiple wheels 613. Preferably, one end of the adjusting member 615 extends out of the seat 611 near the front opening 112, facilitating operator control of the adjusting member 615's rotation. Since the worm gear structure is a common existing technology, it will not be described in detail here, and is only briefly shown in the accompanying drawings.

[0044] Furthermore, the top of the preferred wheel body 613 has a contact surface 6131 for contacting the base 21, and the bottom of both sides of the base 21 has a friction-increasing surface 211 for increasing the friction between the wheel body and the contact surface 6131.

[0045] The resistance-increasing surface 211 is an inclined surface, tilting outwards and upwards; the contact surface 6131 is a conical surface, converging upwards; the inclination angles of the resistance-increasing surface 211 and the contact surface 6131 are the same. When the base 21 is placed between the two base bodies 611, the two resistance-increasing surfaces 211 will respectively contact and abut against the multiple contact surfaces 6131 on both sides. At this time, the force of the multiple elastic elements 614 on the base body 612 will act on the base 21 through the multiple wheels 613, so that the base 21 is driven by the inward force of the horizontal direction on both sides to center its position on the support plate 12. At the same time, the upward force of the base 21 on both sides reduces the friction between it and the support plate 12 to facilitate the movement of the circuit breaker 2. When the circuit breaker 2 moves into place on the support plate 12, during the process of fixing the circuit breaker 2 to the support plate 12 through the multiple screws 5, the base 21 will drive the base body 612 on both sides to move against the force of the multiple elastic elements 614 through the multiple wheels 613 in contact with it.

[0046] Furthermore, preferably, the inner walls on both sides of the width of the main body 11 have guide surfaces 114 above the support plate 12 for contacting the movable plate 616 and driving the movable plate 616 to move relative to the seat 611.

[0047] The distance between the two guide surfaces 114 near the front opening 112 is greater than the distance between the two guide surfaces 114 near the rear opening 113. This causes the corresponding movable plate 616 to move relative to the base 611 as the base 611 moves relative to the support plate 12. When the base 611 moves to its limit position towards the front opening 112, the corresponding movable plate 616 moves outward relative to the base 611 to its limit position. At this time, the force exerted by the multiple elastic elements 614 on the base 612 is minimal, meaning that the upward force exerted by the multiple elastic elements 614 on the circuit breaker 2 through the multiple wheels 613 is minimal. When the base 611 moves to its limit position away from the front opening 112, the corresponding movable plate 616 moves inward relative to the base 611 to its limit position. At this time, the force exerted by the multiple elastic elements 614 on the base 612 is maximum, meaning that the upward force exerted by the multiple elastic elements 614 on the circuit breaker 2 through the multiple wheels 613 is maximum. In this embodiment, it is preferable that when the seat 611 moves to its limit position in the direction close to the front opening 112, the base 21 that contacts the multiple wheels 613 and the support plate 12 remain in contact and abut against each other (the elastic force of the multiple elastic elements 614 reduces the friction between the base 21 and the support plate 12); and it is also preferable that when the seat 611 moves to its limit position in the direction away from the front opening 112, there is a gap between the base 21 that contacts the multiple wheels 613 and the support plate 12.

[0048] The baffle 62 has a rectangular plate-like structure, with its two ends fixedly connected to one end of the length direction of each of the two bases 611. The length direction of the baffle 62 is perpendicular to the length direction of the bases 611, and the two bases 611 are symmetrically distributed relative to the baffle 62. In this embodiment, it is preferable that the two auxiliary components 61 are connected by the baffle 62 to form a whole; and preferably, when the base 611 moves to its limit position towards the front opening 112 and the circuit breaker 2 moves relative to the base 611 towards the baffle 62 until the base 21 contacts and abuts against the baffle 62, the circuit breaker 2 is accurately positioned on the support plate 12.

[0049] The control element 63 is installed on one side of the baffle 62 and is used to control the two adjusting elements 615 to rotate synchronously relative to their respective bases 612, thereby driving the multiple wheels 613 on both sides to rotate synchronously in opposite directions to drive the circuit breaker 2 to move. In this embodiment, the control element 63 is preferably two synchronously running servo motors, which are installed at the ends of the corresponding adjusting elements 615 and are used to drive the corresponding adjusting elements 615 to rotate relative to the base 612; and preferably, the two servo motors drive the two adjusting elements 615 to rotate synchronously and in opposite directions; since servo motors with the above functions are common prior art, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0050] The operating component 64 is rotatably mounted on the support plate 12. It has a cylindrical structure, with its rotation axis coinciding with its own axis and parallel to the length direction of the support plate 12. One end of the operating component 64 extends out of the rear opening 113, facilitating operator control of its rotation. Its rotation drives the two seats 611 to move synchronously and in the same direction relative to the support plate 12. In this embodiment, the operating component 64 preferably drives the two seats 611 via a screw drive. Preferably, when a seat 611 moves to its limit position away from the front opening 112, the end of one seat 611 extending out of the rear opening 113 will form a protective layer above the structure where the operating component 64 extends. Since screw drives are common existing technology, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0051] The implementation principle of a solid-state cabinet in this application embodiment is as follows: When it is necessary to remove, repair or replace the circuit breaker 2, first remove several front cover plates 13 and several rear cover plates 14, then disconnect the outgoing and incoming lines of the circuit breaker 2, and then disconnect the circuit connection between the circuit breaker 2 and the quick-connect plug 4 at the front opening 112. Then remove several screws 5. At this time, the circuit breaker 2 is in a state where it can be moved with the help of the auxiliary device 6. After that, move the transfer cart to the side of the rear opening 113 of the housing 1 and wait for the circuit breaker 2 to be transferred and placed. Then, first rotate the operating part 64 to drive the base 611 away from the front opening 112. When the circuit breaker is moved to its limit position, the upward force exerted by the auxiliary component 61 on the circuit breaker 2 through multiple wheels 613 will increase, thereby reducing the friction between the base 21 of the circuit breaker 2 and the support plate 12, making the operation more time-saving and labor-saving. Then, the two adjusting components 615 are driven to rotate synchronously by the control component 63, and the circuit breaker 2 is driven to move away from the cavity 111 relative to the base 611 through multiple rotating wheels 613. When the circuit breaker 2 is about to leave the base 611, the staff can help place the circuit breaker 2 on the transfer vehicle. The repaired circuit breaker 2 or the new circuit breaker 2 is also moved to the rear opening 113 side of the housing 1 by a transfer vehicle. After the circuit breaker 2 is moved so that it partially contacts the base 611 through multiple wheels 613, the controller 3 drives the two adjusting parts 615 to rotate synchronously. The multiple rotating wheels 613 drive the circuit breaker 2 relative to the base 611 to a position where it contacts and abuts the baffle 62. Then, the rotating operating part 64 drives the base 611 to move towards the front opening 112 to its limit position. During this process, the upward force applied to the circuit breaker 2 by the auxiliary component 61 through the multiple wheels 613 will be reduced, which will increase the friction between the base 21 of the circuit breaker 2 and the support plate 12 to improve the final positional stability of the circuit breaker 2 on the support plate 12. Then, after the circuit breaker 2 is installed and positioned by multiple screws 5, the solid cabinet can be installed in the same way as the previous removal operation.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
