Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and in particular to an outdoor fully insulated 10KV disconnecting switch. Background Technology

[0002] Currently, there are many types of disconnecting switches used in power grid transmission and distribution lines. Different disconnecting switches are required for different power grid levels. In 10kV high-voltage transmission lines, the disconnecting switch structure used is as follows: insulators are installed at both ends of the support frame, and a conductive plate is installed below each insulator. The connecting rod between the two conductive plates is configured as a flexible snap-fit ​​connection with one end rotatable and the other end capable of opening or closing. This type of disconnecting switch is convenient and safe to operate, and it has been widely used to this day. Operators can operate it from less than three meters away from the 10kV high-voltage line by holding an insulated rod, thus achieving the control of power outages and restorations on the 10kV high-voltage line. However, in long-term use, it has been found that while this structure is practical, there are still limitations.

[0003] However, the outdoor fully insulated 10KV disconnect switches in related technologies still have shortcomings. When the insulators are damaged, it is not easy to disassemble and replace them, which reduces the effectiveness of use. At the same time, the related 10KV disconnect switches are generally manual switches, which is not only troublesome but also poses safety hazards. Therefore, we propose an outdoor fully insulated 10KV disconnect switch to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and propose an outdoor fully insulated 10KV disconnect switch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An outdoor fully insulated 10kV disconnector includes a base for fixing the outdoor fully insulated 10kV disconnector and two insulators. A disassembly and replacement mechanism is provided between the base and the insulators. A connecting plate is fixedly connected to the top of the insulator. A device clamp is fixedly connected to the top of the left connecting plate, and a device clamp is fixedly connected to the top of the right connecting plate. A pressure plate is fixedly connected to the top of the device clamp. A contact blade is rotatably provided on the top of the pressure plate. An electric disconnector mechanism is provided between the pressure plate, the contact blade, and the device clamp.

[0007] As a preferred embodiment of this utility model, the top of the base is provided with three elongated fixing holes.

[0008] In a preferred embodiment of this utility model, the first device clamp is fixedly connected to the top of the left connecting plate by two screws, and the second device clamp is movably abutted between the pressure plate and the right connecting plate. Both the pressure plate and the second device clamp are fixedly connected to the top of the right connecting plate by four screws.

[0009] In a preferred embodiment of this utility model, the electric disconnect switch mechanism includes two support seats fixedly connected to the top of the pressure plate and a conductive sheet fixedly connected to the top of the connecting plate on the left side. A rotating shaft is rotatably connected to the side of the two support seats that are close to each other. The contact blade is fixedly sleeved on the outside of the rotating shaft. A driven bevel gear is fixedly connected to the front end of the rotating shaft. A drive motor is fixedly connected to the bottom inner wall of the front support seat. A rotating shaft is fixedly connected to the output shaft of the drive motor. A driving bevel gear is fixedly connected to the top end of the rotating shaft. The driving bevel gear meshes with the driven bevel gear. The contact blade moves against the outside of the conductive sheet.

[0010] As a preferred embodiment of this invention, an abutment groove is provided on one side of the contact blade, and the conductive sheet is movably abutted in the abutment groove.

[0011] As a preferred embodiment of this utility model, the disassembly and replacement mechanism includes a limiting ring fixedly sleeved on the outside of the insulator and an insert block fixedly connected to the bottom of the insulator. The top of the base has two slots, and the insert block is movably inserted into the slots. The upper and lower inner walls of the insert block are rotatably connected to the same threaded rod. A trapezoidal plate is threadedly sleeved on the outside of the threaded rod. Triangular blocks are movably abutted on both inclined surfaces of the trapezoidal plate. Limiting plates are fixedly connected to the sides of the two triangular blocks that are far apart from each other. The limiting ring movably abuts against the top of the base, and the two limiting plates movably abut against the inner wall of the top of the base.

[0012] As a preferred embodiment of this utility model, guide rods and compression springs are fixedly connected to the inner walls of both sides of the insert block. A movable plate is fixedly connected to one end of the compression spring. Two movable plates are fixedly connected to the top of the corresponding triangular blocks. The two movable plates are slidably sleeved on the outside of the corresponding guide rods. The compression spring is sleeved on the outside of the guide rods.

[0013] As a preferred embodiment of this utility model, a handwheel is fixedly connected to the bottom end of the threaded rod, a fixing screw is threadedly connected to the bottom of the handwheel, a threaded groove is opened at the bottom of the insert block, the fixing screw is threadedly sleeved in the threaded groove, two limiting rods are fixedly connected to the upper and lower inner walls of the insert block, and the trapezoidal plate is slidably sleeved on the outside of the two limiting rods.

[0014] In this utility model, an outdoor fully insulated 10KV disconnect switch achieves excellent insulation through two insulators. When disconnected, the drive motor is started, and the output shaft of the drive motor drives the rotating shaft and the active bevel gear to rotate. The active bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the rotating shaft to rotate. The rotation of the rotating shaft causes the contact blade to deflect to the right and disconnect from the conductive sheet, thereby achieving the disconnection effect. When closed, the drive motor is started in reverse, causing the rotation of the rotating shaft to drive the contact blade to deflect to the left and engage with the outside of the conductive sheet, thus achieving the closed effect.

[0015] In this utility model, an outdoor fully insulated 10KV disconnector switch allows for easy replacement of damaged insulators. By loosening the fixing screw, the screw exits the threaded groove without securing the handwheel. Rotating the threaded rod via the handwheel, and with the two limit rods in place, the threaded rod causes the trapezoidal plate to move downwards without compressing the triangular block. At this point, under the spring force of the compression spring, the two moving plates, the triangular block, and the limit plate retract into the insert, thus eliminating the need for limiting or fixing the insert and insulator. The insert and insulator can then be removed from the base for replacement. The new insulator is then connected to the equipment clamp and the equipment... Connect the second wire clamp, then insert the plug into the slot, and make the limiting ring abut against the top of the base. Finally, rotate the handwheel and the threaded rod in the opposite direction, so that the threaded rod rotates and the trapezoidal plate moves up to press the two triangular blocks outward. The two triangular blocks drive the two limiting plates to move outward and abut against the top inner wall of the base, thereby limiting and fixing the plug and the insulator to the top of the base. In order to ensure the stability of the installation, finally tighten the fixing screw, so that the fixing screw is screwed into the threaded groove to lock the threaded rod, thereby locking the trapezoidal plate and preventing the limiting plate from retracting inward and affecting the stability of the insulator installation.

[0016] This utility model has a reasonable structural design. Through the electric disconnecting switch mechanism, it is easy to open and close the contact blades by electric drive, eliminating manual operation and improving safety. Furthermore, through the disassembly and replacement mechanism, it is not only convenient to quickly, efficiently and reliably disassemble and replace the insulator, but also avoids the reduction of the full insulation effect due to insulator damage, thus improving the performance of use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 An outdoor fully insulated 10KV disconnect switch includes a base 1 for fixing the outdoor fully insulated 10KV disconnect switch and two insulators 2. A disassembly and replacement mechanism 8 is provided between the base 1 and the insulators 2. A connecting plate 3 is fixedly connected to the top of the insulator 2. A device clamp 4 is fixedly connected to the top of the left connecting plate 3. A device clamp 5 is fixedly connected to the top of the right connecting plate 3. A pressure plate 6 is fixedly connected to the top of the device clamp 5. A contact blade 72 is rotatably provided on the top of the pressure plate 6. An electric disconnect switch mechanism 7 is provided between the pressure plate 6, the contact blade 72 and the device clamp 4.

[0024] Furthermore, the top of the base 1 is provided with three long fixing holes 11, which facilitate fine-tuning of the base 1, making the installation of the base 1 more convenient and easier to use.

[0025] Furthermore, the first equipment clamp 4 is fixedly connected to the top of the left connecting plate 3 by two screws, and the second equipment clamp 5 is movably abutted between the pressure plate 6 and the right connecting plate 3. The pressure plate 6 and the second equipment clamp 5 are both fixedly connected to the top of the right connecting plate 3 by four screws, which facilitates the connection of the second equipment clamp 5 and the first equipment clamp 4 to the insulator 2 respectively, so as to provide insulation for the 10KV disconnecting switch.

[0026] Furthermore, refer to Figure 1 and Figure 4 As shown, the electric disconnect switch mechanism 7 includes two support seats 71 fixedly connected to the top of the pressure plate 6 and a conductive sheet 73 fixedly connected to the top of the connecting plate 3 on the left side. A rotating shaft 77 is rotatably connected to the side of the two support seats 71 that is close to each other. The contact blade 72 is fixedly sleeved on the outside of the rotating shaft 77. A driven bevel gear 78 is fixedly connected to the front end of the rotating shaft 77. A drive motor 74 is fixedly connected to the bottom inner wall of the front support seat 71. A rotating shaft 75 is fixedly connected to the output shaft of the drive motor 74. A driving bevel gear 76 is fixedly connected to the top end of the rotating shaft 75. The driving bevel gear 76 meshes with the driven bevel gear 78. The contact blade 72 moves against the outside of the conductive sheet 73. An abutment groove is opened on one side of the contact blade 72, and the conductive sheet 73 moves against the abutment groove.

[0027] Using the above scheme: When this new type of outdoor fully insulated 10KV disconnecting switch is in use, it can achieve a good insulation effect through two insulators 2. When disconnected, the drive motor 74 is started. The output shaft of the drive motor 74 drives the rotating shaft 75 and the driving bevel gear 76 to rotate. The driving bevel gear 76 drives the driven bevel gear 78 to rotate. The driven bevel gear 78 drives the rotating shaft 77 to rotate. The rotation of the rotating shaft 77 causes the contact blade 72 to deflect to the right and disconnect from the conductive sheet 73, thereby achieving the disconnection effect. When closed, the drive motor 74 is started in reverse, so that the rotation of the rotating shaft 77 causes the contact blade 72 to deflect to the left and engage with the outside of the conductive sheet 73, thus achieving the closed effect.

[0028] Furthermore, refer to Figure 2 and Figure 3As shown, the disassembly and replacement mechanism 8 includes a limiting ring 801 fixedly sleeved on the outside of the insulator 2 and an insert block 802 fixedly connected to the bottom end of the insulator 2. Two slots 803 are opened on the top of the base 1. The insert block 802 is movably inserted into the slots 803. A threaded rod 809 is rotatably connected between the upper and lower inner walls of the insert block 802. A trapezoidal plate 805 is threadedly sleeved on the outer side of the threaded rod 809. Triangular blocks 806 are movably abutted against on both inclined surfaces of the trapezoidal plate 805. Limiting plates 804 are fixedly connected to the sides of the two triangular blocks 806 that are far apart from each other. The limiting ring 801 movably abuts against the top of the base 1, and the two limiting plates 804 movably abut against the inner wall of the top of the base 1. The inner walls of both sides of the insert block 802 are fixedly connected to… There is a guide rod 813 and a compression spring 814. One end of the compression spring 814 is fixedly connected to a movable plate 807. Two movable plates 807 are respectively fixedly connected to the top of the corresponding triangular block 806. The two movable plates 807 are respectively slidably sleeved on the outside of the corresponding guide rod 813. The compression spring 814 is sleeved on the outside of the guide rod 813. The bottom end of the threaded rod 809 is fixedly connected to a handwheel 810. The bottom of the handwheel 810 is threadedly connected to a fixing screw 811. The bottom of the insert block 802 is provided with a threaded groove 812. The fixing screw 811 is threadedly sleeved in the threaded groove 812. Two limiting rods 808 are fixedly connected to the upper and lower inner walls of the insert block 802. The trapezoidal plate 805 is slidably sleeved on the outside of the two limiting rods 808.

[0029] Using the above scheme: When insulator 2 is damaged, it needs to be replaced in time to avoid reducing the overall insulation effect due to the damage of insulator 2. First, loosen the fixing screw 811 so that the fixing screw 811 exits the threaded groove 812 without fixing the handwheel 810. Rotate the threaded rod 809 by the handwheel 810. Under the limit of the two limit rods 808, the threaded rod 809 drives the trapezoidal plate 805 to move down without squeezing the triangular block 806. At this time, under the elastic force of the compression spring 814, the two moving plates 807, the triangular block 806 and the limit plate 804 move closer to each other and retract into the insert 802, thus not limiting and fixing the insert 802 and the insulator 2. At this time, the insert 802 and the insulator 2 can be removed from the base 1 for replacement. The equipment clamp 1 4 and the equipment clamp 2 5 are both connected to the connecting plate 3 by screws and can be directly removed. Then the insulator can be removed. Remove and replace the insulator 2 to ensure insulation effectiveness. Then connect the new insulator 2 to the equipment clamp 4 and the equipment clamp 5 respectively. Next, insert the plug 802 into the slot 803, and make the limiting ring 801 abut against the top of the base 1. Finally, rotate the handwheel 810 and the threaded rod 809 in the opposite direction, so that the threaded rod 809 rotates and the trapezoidal plate 805 moves upward to press the two triangular blocks 806 outward. The two triangular blocks 806 drive the two limiting plates 804 to move outward and abut against the top inner wall of the base 1, thereby limiting and fixing the plug 802 and the insulator 2 to the top of the base 1. To ensure the stability of the installation, finally tighten the fixing screw 811, so that the fixing screw 811 is screwed into the threaded groove 812 to lock the threaded rod 809, thereby locking the trapezoidal plate 805 and preventing the limiting plate 804 from retracting inward and affecting the stability of the insulator 2 installation.
