[0029] An operating mechanism is provided on the insulating plate 6. The operating mechanism drives the insulating plate 6 to move up and down reciprocally at the bottom of the transformer valve side copper busbar 2.

[0030] In this embodiment, the connection device moves the insulating plate 6 up and down via the operating mechanism until the moving contact on the insulating plate 6 is inserted into the stationary contact at the bottom of the transformer valve-side copper busbar 2, thus completing the connection and stopping the movement of the insulating plate 6.

[0031] Example 2

[0032] This utility model is used for the connection device between the TVS tube and the copper busbar on the valve side of the transformer, such as Figure 1 As shown, it includes a connecting wall 1, and multiple transformer valve side copper busbars 2 are evenly distributed and fixed on the top of one side of the connecting wall 1. The bottom of the transformer valve side copper busbars 2 is provided with stationary contacts. There are six transformer valve side copper busbars 2 in total. A single rectifier unit has a total of twenty-four transformer valve side copper busbars 2, which are arranged in groups of six, for a total of four groups.

[0033] Connecting rods 3 are fixed at both ends on one side of the connecting wall 1. The two connecting rods 3 are located at the bottom of the transformer valve-side copper busbar 2. A TVS box 4 is installed at the bottom of the connecting rods 3, and the TVS box 4 is fixedly connected to the connecting wall 1. An insulating plate 6 is installed between the pair of connecting rods 3. The two ends of the insulating plate 6 are connected to the connecting rods 3 respectively. The connecting wire of the TVS box 4 passes through the insulating plate 6, so that the moving contact is fixed to the top of the insulating plate 6. A fixing ring is fixed to the outside of the moving contact. By observing the fixing ring, it can be confirmed whether the moving contact is in correct contact with the stationary contact at the bottom of the transformer valve-side copper busbar 2.

[0034] Furthermore, a conduit is provided on the inner side of the insulating plate 6, and the connecting wire of the TVS box 4 passes through the conduit on the inner side of the insulating plate 6, and the conduit is fixed to the insulating plate 6.

[0035] like Figure 2 As shown, the operating mechanism includes a pair of fixed plates 7, which are located between the insulating plate 6 and the copper busbar 2 on the transformer valve side and at the bottom of the connecting wall 1, respectively. A screw 8 is movably connected between the fixed plates 7, and a lifting plate 9 is threadedly connected to the screw 8. The lifting plate 9 is fixedly connected to the insulating plate 6.

[0036] A drive unit for rotating the drive screw 8 is provided at the bottom of the fixing plate 7 located at the bottom of the connecting wall 1.

[0037] The lifting plate 9 is fixed to the insulating plate 6 by screws. The connection of the screws allows the insulating plate 6 to move during the movement of the lifting plate 9, and also facilitates the disassembly of the lifting plate 9 and the insulating plate 6.

[0038] Example 3

[0039] This utility model is used for the connection device between the TVS tube and the copper busbar on the valve side of the transformer, such as Figure 1As shown, it includes several transformer valve-side copper busbars 2 and TVS box 4 fixed on the connecting wall 1. The TVS box 4 is located at the bottom of the transformer valve-side copper busbars 2. A pair of connecting rods 3 are provided on the connecting wall 1. An insulating plate 6 is provided between the pair of connecting rods 3. The two ends of the insulating plate 6 are respectively connected to the connecting rods 3. The connecting wire of the TVS box 4 passes through the insulating plate 6 and fixes the moving contact to the top of the insulating plate 6. The moving contact corresponds to the stationary contact at the bottom of the transformer valve-side copper busbars 2.

[0040] An operating mechanism is provided on the insulating plate 6. The operating mechanism drives the insulating plate 6 to move up and down reciprocally at the bottom of the transformer valve side copper busbar 2.

[0041] like Figure 2 As shown, the operating mechanism includes a pair of fixed plates 7, which are located between the insulating plate 6 and the copper busbar 2 on the transformer valve side and at the bottom of the connecting wall 1, respectively. A screw 8 is movably connected between the fixed plates 7, and a lifting plate 9 is threadedly connected to the screw 8. The lifting plate 9 is fixedly connected to the insulating plate 6.

[0042] A drive unit for rotating the drive screw 8 is provided at the bottom of the fixing plate 7 located at the bottom of the connecting wall 1.

[0043] like Figure 3 As shown, the drive unit includes a worm gear 11, which is fixed to the bottom of the screw 8. A worm 12 is meshed with one side of the worm gear 11. The worm 12 is movably connected to a fixed plate 7 located at the bottom of the connecting wall 1. A handwheel 13 is fixedly connected to one end of the worm 12.

[0044] A guide rod 10 is provided on one side of the lifting plate 9. The guide rod 10 passes through the lifting plate 9 and is slidably connected to the lifting plate 9. The two ends of the guide rod 10 are respectively fixedly connected to the upper and lower fixed plates 7.

[0045] When this utility model is in operation, the operator rotates the handwheel 13 from the ground. By rotating the handwheel 13, the worm gear 12 is driven to rotate. Since the worm gear 12 and the worm wheel 11 are meshed with each other, when the worm gear 12 rotates, the worm wheel 11 rotates, thereby driving the screw 8 to rotate. The lifting plate 9 connected to the screw 8, under the limiting action of the guide rod 10, drives the insulating plate 6 to move up and down along the screw 8.

[0046] Example 4

[0047] This embodiment is based on the above embodiment 3, such as Figure 3As shown, in this embodiment, a locking pin 19 passes through the handwheel 13 and is inserted into the fixing plate 7. The fixing plate 7 has several limiting holes positioned opposite the locking pin 19, and these holes are evenly distributed along the circumference of the handwheel 13. When the handwheel 13 is rotated to move the insulating plate 6 and complete the connection between the moving and stationary contacts, the locking pin 19 is inserted into the corresponding limiting hole to limit the handwheel 13, preventing the moving and stationary contacts from disconnecting.

[0048] Example 5

[0049] The utility model is a connection device for TVS tubes and transformer valve-side copper busbars, such as Figure 1 As shown, it includes several transformer valve-side copper busbars 2 and TVS box 4 fixed on the connecting wall 1. The TVS box 4 is located at the bottom of the transformer valve-side copper busbars 2. The adjacent transformer valve-side copper busbars 2 are distributed at equal distances, and the several transformer valve-side copper busbars 2 are distributed in a straight line.

[0050] A pair of connecting rods 3 are provided on the connecting wall 1, and an insulating plate 6 is provided between the pair of connecting rods 3. The two ends of the insulating plate 6 are respectively connected to the connecting rods 3.

[0051] Furthermore, a connecting sleeve 5 is slidably connected to the connecting rod 3, and the connecting sleeve 5 is connected to the insulating plate 6 on the opposite side of the insulating plate 6 through a snap-fit ​​mechanism.

[0052] like Figure 4 As shown, the snap-fit ​​mechanism includes a snap-fit ​​plate 14. The connecting sleeve 5 has a groove along the axial direction on the side opposite to the insulating plate 6. One end of the insulating plate 6 is snapped into the groove, and the snap-fit ​​plate 14 is located in the groove and is movably connected to the connecting sleeve 5. A snap-fit ​​rod 16 is connected to one side of the snap-fit ​​plate 14. A sliding plate 15 is fixedly connected to the bottom of the snap-fit ​​rod 16. The sliding plate 15 is movably connected to the connecting sleeve 5. A spring 17 is provided at the bottom of the sliding plate 15. One end of the spring 17 is fixedly connected to the sliding plate 15, and the other end is fixedly connected to the connecting sleeve 5.

[0053] When the insulating plate 6 needs to be installed on the connecting sleeve 5, push the snap-fit ​​plate 14 upwards to insert one end of the insulating plate 6 into the sliding groove, and then release the snap-fit ​​plate 14. Since the snap-fit ​​plate 14 and the snap-fit ​​rod 16 are fixedly connected, and the snap-fit ​​rod 16 is fixedly connected to the sliding plate 15, the spring 17 is stretched during the upward pushing of the snap-fit ​​plate 14. After releasing the snap-fit ​​plate 14, the spring 17 loses its tension, thereby pulling the sliding plate 15 and causing the snap-fit ​​plate 14 to return to its original position. Because the insulating plate 6 is inserted into the sliding groove at this time, the snap-fit ​​plate 14, under the action of the spring 17, cooperates with the connecting sleeve 5 to snap the insulating plate 6 in place. The snap-fit ​​mechanism design makes the installation and removal of the insulating plate 6 more convenient and quick.

[0054] The connecting wire of TVS box 4 passes through the insulating plate 6 and fixes the moving contact to the top of the insulating plate 6. The moving contact corresponds to the stationary contact at the bottom of the transformer valve side copper busbar 2.

[0055] An operating mechanism is provided on the insulating plate 6. The operating mechanism drives the insulating plate 6 to move up and down reciprocally at the bottom of the transformer valve side copper busbar 2.

[0056] Furthermore, the operating mechanism includes a fixed plate 7, a screw 8, a lifting plate 9, a guide rod 10, a worm gear 11, a worm 12, and a handwheel 13. Two fixed plates 7 are fixed on one side of the wall 1, and the two fixed plates 7 are distributed vertically. A screw 8 is rotatably connected between the two fixed plates 7. The outer side of the screw 8 is threadedly connected to the lifting plate 9. The lifting plate 9 is connected to the insulating plate 6. A guide rod 10 is slidably connected to the inner side of one side of the lifting plate 9. The guide rod 10 is fixedly connected to the fixed plate 7. A worm gear 11 is fixed to the bottom of the screw 8. A worm 12 is meshed with one side of the worm gear 11. The worm 12 is rotatably connected to the fixed plate 7 located at the bottom. A handwheel 13 is fixed to one end of the worm 12. An insulating sleeve is wrapped around the outside of the handwheel 13.

[0057] When it is necessary to distribute the voltage on the transformer valve-side copper busbar 2 through the TVS box 4, insert the connecting wire at the top of the TVS box 4 into the inside of the insulating plate 6. The connecting wire passes through the conductor tube inside the insulating plate 6, and the moving contact at the top of the connecting wire is fixed to the top of the insulating plate 6. Rotate the handwheel 13, which drives the worm gear 12 to rotate. The worm wheel 11, which is meshed with the worm gear 12, rotates accordingly. Since the worm wheel 11 is fixedly connected to the screw 8, the rotation of the worm wheel 11 drives the screw 8 to rotate. The rotation of the screw 8 causes the lifting plate 9 to move the insulating plate 6. The movement of the insulating plate 6 causes the moving contact at the top of the insulating plate 6 to insert into the inside of the transformer valve-side copper busbar 2, so that the moving contact contacts the stationary contact at the bottom of the transformer valve-side copper busbar 2.

[0058] Example 6

[0059] This embodiment is based on embodiment 5 above, such as Figure 5 As shown, in the connection device of this utility model for connecting TVS tubes and transformer valve-side copper busbars, multiple guide tubes 18 are evenly distributed and fixed at the bottom of the transformer valve-side copper busbar 2 and the insulating plate 6, such as... Figure 6 As shown, the bottom of the guide tube 18 is trumpet-shaped, and the inner diameter of the bottom gradually increases from the inside to the outside.

[0060] The design of the guide tube 18 allows the moving contact of the connecting line of the TVS box 4 to be better connected to the stationary contact at the bottom of the transformer valve side copper busbar 2.
