Description

Technical Field

[0001] This application relates to the technical field of high-voltage switchgear, and in particular to a high-voltage switchgear. Background Technology

[0002] High-voltage switchgear is a complete set of power distribution equipment used in power systems for power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is mainly used indoors, and circuit breakers are usually installed inside the switchgear. The circuit breakers are usually moved to the switchgear by handcart and then pushed into the switchgear.

[0003] In related technologies, switch cabinets include a cabinet body and a cabinet door. The cabinet door is rotatably connected to the cabinet body, and the cabinet body has a placement slot.

[0004] Because different models of switchgear have different heights, staff usually need to use different models of handcarts to ensure that the height of the circuit breaker is the same as the height of the slot wall, so that the circuit breaker can be pushed into the slot. If only a single model of handcart is available, the switchgear is difficult to fit, and staff need to manually raise or lower the circuit breaker, making the operation very cumbersome. Summary of the Invention

[0005] To address the issue of different switchgear models being difficult to adapt to a single model of handcart, this application provides a high-voltage switchgear.

[0006] This application provides a high-voltage switchgear, which adopts the following technical solution: A high-voltage switchgear includes a cabinet body and a cabinet door. The cabinet door is rotatably connected to the cabinet body. The cabinet body has a placement slot. A rotating shaft is rotatably connected to the cabinet body. A placement plate is provided on the rotating shaft. The placement plate is used to abut against a circuit breaker trolley.

[0007] By adopting the above technical solution, the staff can rotate the placement plate so that it can abut against the platform of the handcart, allowing the circuit breaker to reach the placement slot via the handcart and the placement plate. This allows the switch cabinet to be compatible with the same model of handcart, reducing the need for staff to purchase different models of handcarts and lowering the difficulty of operation for staff.

[0008] Optionally, a movable bar is slidably connected in the placement slot, and a movable block is provided on the movable bar. The movable block is located on the moving path of the circuit breaker installation placement slot, and the movable bar is engaged with a rotating shaft. When the circuit breaker is installed in the placement slot, the movable bar drives the placement plate to rotate through the rotating shaft, and the placement plate is located on the side of the circuit breaker away from the bottom wall of the placement slot.

[0009] By adopting the above technical solution, when the circuit breaker is installed in the placement slot, the moving block is located on the moving path of the circuit breaker installation slot, causing the circuit breaker to move the moving block. The moving block then moves the moving strip, which is engaged with the rotating shaft, allowing the rotating shaft to rotate the placement plate. This enables the placement plate to rotate automatically when the circuit breaker is pushed into the placement slot, reducing the number of steps required by the operator and further speeding up the operation of moving the circuit breaker. By positioning the placement plate on the side of the circuit breaker away from the bottom wall of the placement slot, the placement plate restricts the direct removal of the circuit breaker from the placement slot, thus ensuring that the circuit breaker is stably positioned within the placement slot.

[0010] Optionally, the rotating shaft is provided with a limiting block, and the placement plate is provided with a limiting groove for the limiting block to be inserted; when the limiting block is inserted into the limiting groove, the rotating shaft can drive the placement plate to rotate.

[0011] By adopting the above technical solution, the placement plate and the rotating shaft are fixed together by inserting the limiting block into the limiting groove, so that the rotating shaft can drive the placement plate to move; the operator slides the placement plate to let the placement block disengage from the limiting groove, thereby unlocking the placement plate and the rotating shaft, so that the operator can put down the placement plate without moving the circuit breaker, which makes it easier for the operator to take the circuit breaker out of the placement groove and reduces the obstruction of the circuit breaker by the placement plate.

[0012] Optionally, a moving groove is provided on the rotating shaft, and an elastic element is provided in the moving groove. The elastic element drives the limiting block to protrude out of the moving groove. An operating bar is slidably connected to the cabinet body. The operating bar is used to drive the limiting block to disengage from the limiting groove.

[0013] By adopting the above technical solution, the limit block is driven to protrude from the moving groove by the elastic element, so that the limit block can be smoothly positioned in the limit groove, thereby fixing the rotating shaft and the placement plate to each other; the operator slides the operating bar, so that the operating bar drives the limit block to disengage from the limit groove, thereby releasing the fixing of the rotating shaft and the placement plate, so that the operator can quickly rotate the placement plate.

[0014] Optionally, the placement plate is provided with a receiving groove, and a receiving plate is slidably connected in the receiving groove, the receiving plate being used to extend the length of the placement plate.

[0015] By adopting the above technical solution, the receiving plate slides in the receiving groove, which can extend the length of the placement plate, so that some placement plates that are not long enough can smoothly meet the handcart, and the switch cabinet can adapt to more types of handcarts.

[0016] Optionally, a fixing strip is slidably connected to the placement plate, and a fixing groove is provided on the groove wall of the receiving groove for the fixing strip to be inserted; when the fixing strip is located in the fixing groove, the fixing strip is located on the side of the receiving plate away from the bottom wall of the receiving groove.

[0017] By adopting the above technical solution, the fixing strip is inserted into the fixing groove. The fixing strip is located on the side of the receiving plate away from the bottom wall of the receiving groove, so that the fixing strip can limit the receiving plate, making it less likely for the receiving plate to protrude from the receiving groove. When the receiving plate is not needed, the receiving plate will not protrude from the receiving groove, reducing the occurrence of the problem of the receiving plate protruding from the placing plate during the rotation of the placing plate and causing the length to be too long, so that the staff can adjust whether the receiving plate is needed.

[0018] Optionally, the placement plate is provided with a receiving block, and the receiving block is provided with a receiving inclined surface. The distance between the receiving inclined surface and the receiving plate gradually increases along the direction from the receiving plate to the bottom wall of the receiving groove.

[0019] By adopting the above technical solution, the distance between the receiving inclined surface and the receiving plate gradually increases along the direction from the receiving plate to the bottom wall of the receiving groove. The circuit breaker can move sequentially along the surface of the trolley, the surface of the receiving plate, the receiving inclined surface and the surface of the placement plate into the placement groove. This allows the receiving inclined surface to buffer the surface of the receiving plate and the surface of the placement plate, avoiding the situation where the circuit breaker is difficult to move when moving on the receiving plate because the surfaces of the receiving plate and the placement plate are not coplanar.

[0020] Optionally, the receiving block is slidably connected to the receiving groove, and the receiving block has a through hole for inserting a fixing strip; when the fixing strip passes through the through hole and is inserted into the fixing groove, the receiving block does not protrude from the placement plate.

[0021] By adopting the above technical solution, the fixing strip is inserted into the fixing groove through the perforation, so that the fixing strip limits the receiving block and prevents the receiving block from protruding from the placement plate. Thus, the receiving block will not protrude from the receiving groove even if the receiving plate is not pulled out. When the placement plate is against the trolley and the receiving block protrudes, the circuit breaker moves and, because there is no other structure to support the receiving block, the force exerted by the circuit breaker on the receiving block is too great, which can easily cause damage to the receiving block and affect its subsequent use. The fixing strip limits the receiving block, so that the receiving block is not easily damaged by excessive weight.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The staff rotates the placement plate so that it can abut against the platform of the handcart, allowing the circuit breaker to be transported to the placement slot via the handcart and placement plate. This reduces the need for staff to purchase different models of handcarts and lowers the difficulty of operation.

[0023] 2. When the circuit breaker is installed in the placement slot, the moving block is located on the moving path of the circuit breaker installation slot, causing the circuit breaker to move the moving block. The moving block then moves the moving bar, which is engaged with the rotating shaft, allowing the rotating shaft to rotate the placement plate. This allows the placement plate to rotate automatically when the circuit breaker is pushed into the placement slot, reducing the number of steps required by the operator and speeding up the process of moving the circuit breaker. Furthermore, the placement plate is located on the side of the circuit breaker away from the bottom wall of the placement slot, preventing the circuit breaker from being directly removed from the slot and ensuring that the circuit breaker remains stably positioned within the slot.

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This embodiment discloses a high-voltage switchgear. (Refer to...) Figure 1 A high-voltage switchgear includes a cabinet body 1 and a cabinet door 11, the cabinet door 11 being rotatably connected to the cabinet body 1. A placement slot 12 is provided on the cabinet body 1 for placing circuit breakers.

[0028] Reference Figure 1 and Figure 2A support rod 13 is fixedly connected to the wall of the placement slot 12, and a placement plate 2 is rotatably connected to the support rod 13. The placement plate 2 can abut against the trolley of the circuit breaker, so that the circuit breaker can be moved from the trolley into the placement slot 12.

[0029] Reference Figure 2 and Figure 3 A receiving cavity 121 is provided on the wall of the placement groove 12, and a rotating shaft 14 is rotatably connected inside the receiving cavity 121. The rotating shaft 14 and the support rod 13 are coaxially arranged, and a moving groove 141 is provided on the surface of the rotating shaft 14 near the support rod 13.

[0030] Reference Figure 3 An elastic element 142, including an elastic spring, is provided inside the movable groove 141. One end of the elastic spring is fixedly connected to the groove wall of the movable groove 141, and the other end of the elastic spring is fixedly connected to a limiting block 143, which is pentagonal in shape. The elastic spring drives the limiting block 143 to protrude out of the movable groove 141; that is, when the limiting block 143 is completely inside the movable groove 141, the elastic spring is in a compressed state. A limiting groove 21 for the limiting block 143 to be inserted is provided on the surface of the placement plate 2. When the limiting block 143 is inserted into the limiting groove 21, the placement plate 2 rotates about the support rod 13 and the rotating shaft 14.

[0031] Reference Figure 1 , Figure 3 and Figure 4 An operating groove 15 is provided on the wall of the placement groove 12. An operating bar 151 is slidably connected in the operating groove 15 and slides in the vertical direction. A through hole is provided on the rotating shaft 14 for the operating bar 151 to pass through, and the operating bar 151 passes through the through hole and is inserted into the moving groove 141.

[0032] Reference Figure 3 and Figure 4 The surface of the limiting block 143 is provided with an operation hole 144 for the operation bar 151 to be inserted. The wall of the operation hole 144 is provided with an operation slope 145. The distance between the operation slope 145 and the elastic spring gradually increases in the vertical downward direction, and the operation slope 145 is located on the moving path of the operation bar 151 inserted into the operation hole 144.

[0033] Reference Figure 3 and Figure 4 When the operator slides the operating bar 151 downwards, the operating bar 151 is inserted into the operating hole 144. The operating bar 151 drives the limiting block 143 to move through the operating inclined surface 145, so that the limiting block 143 is disengaged from the limiting groove 21, and the limiting block 143 is released from locking the placement plate 2, allowing the placement plate 2 to rotate freely.

[0034] Reference Figure 1 and Figure 4A movable groove 16 is formed on the surface of the cabinet 1, connecting the moving groove 141 and the placement groove 12. A moving strip 161 is slidably connected within the movable groove 16, extending along the width direction of the cabinet 1. A moving block 162 is fixedly connected to the surface of the moving strip 161, located within the placement groove 12. The moving block 162 is positioned on the moving path of the circuit breaker mounting placement groove 12. Multiple toothed blocks are fixedly connected to the surface of the moving strip 161, meshing with the rotating shaft 14.

[0035] Reference Figure 1 and Figure 4 When the circuit breaker is installed in the placement slot 12, the circuit breaker drives the moving block 162 to slide, which in turn drives the moving bar 161 to slide. The moving bar 161 drives the rotating shaft 14 to rotate, which in turn drives the placement plate 2 to rotate through the limit block 143, so that the placement plate 2 rotates to a vertical position. At this time, the placement plate 2 is located on the side of the circuit breaker away from the bottom wall of the placement slot 12.

[0036] Reference Figure 5 A receiving groove 22 is provided on the surface of the placement plate 2, and a receiving plate 221 is slidably connected in the receiving groove 22. The receiving plate 221 is used to extend the length of the placement plate 2.

[0037] Reference Figure 5 A placement hole 23 communicating with a receiving groove 22 is formed on the surface of the placement plate 2. A receiving block 231 is slidably connected within the placement hole 23. One side surface of the receiving block 231 is coplanar with the surface of the placement plate 2, and the other side surface of the receiving block 231 is coplanar with the surface of the receiving plate 221. A receiving inclined surface 232 is formed on the receiving block 231. The distance between the receiving inclined surface 232 and the receiving plate 221 gradually increases along the direction from the receiving plate 221 to the bottom wall of the receiving groove 22. The circuit breaker can reach the placement plate 2 along the receiving plate 221 and the receiving inclined surface 232.

[0038] Reference Figure 5 A fixing strip 24 is slidably connected to the placement plate 2, and a fixing groove 241 for inserting the fixing strip 24 is formed on the groove wall of the receiving groove 22. The fixing strip 24 can pass through the placement hole 23, and a through hole 242 for inserting the fixing strip 24 is formed on the surface of the receiving block 231. When the fixing strip 24 is inserted into the fixing groove 241, the receiving plate 221 is located on the side of the fixing strip 24 near the bottom wall of the receiving groove 22. When the fixing strip 24 is inserted into the through hole 242, the receiving block 231 does not protrude from the placement plate 2.

[0039] Reference Figure 5The worker removes the fixing strip 24 from the fixing groove 241, then slides the receiving plate 221 and the receiving block 231, and finally inserts the fixing strip 24 through the through hole 242 into the fixing groove 241, so that the receiving plate 221 is located on the side of the fixing strip 24 away from the bottom wall of the receiving groove 22, thereby fixing the receiving plate 221 and the receiving block 231 with the fixing strip 24.

[0040] The implementation principle of a high-voltage switchgear according to an embodiment of this application is as follows: the operator rotates the placement plate 2, causing the placement plate 2 to slide along the moving bar 161 via the rotating shaft 14, so that the operator can push the circuit breaker from the placement plate 2 into the placement slot 12 to realize the installation of the circuit breaker. At this time, the circuit breaker drives the moving block 162 to slide, causing the moving block 162 to drive the rotating shaft 14 to rotate via the moving bar 161. The rotating shaft 14 drives the placement plate 2 to rotate, so that the placement plate 2 is in a vertical state and the placement plate 2 is located on the side of the circuit breaker away from the bottom wall of the placement slot 12.
