[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 4 As shown, the first embodiment of the device for removing the general cap of the high-voltage bushing of the transformer according to the present invention is shown.

[0023] The device for removing the general cap of the high-voltage bushing of the transformer in this embodiment includes: a base assembly for being detachably fastened to the bushing oil pillow, a general cap removal assembly for clamping the general cap terminal and removing it, and an adjustment assembly for adjusting the relative position of the general cap removal assembly and the general cap terminal, one end of the adjustment assembly is connected to the base assembly, and the other end of the adjustment assembly is connected to the general cap removal assembly.

[0024] The base assembly includes: two clamps 7 capable of adjusting relative positions and a plurality of rubber pad stripping parts for separating the rubber pad adhered to the bottom of the general cap from the flange surface of the casing oil pillow; the rubber pad stripping parts include: a guide tube 3 fastened to the clamp 7, a wedge block 32 installed in the internal slideway of the guide tube 3, and a first adjustment bolt 1 screwed and connected to one end of the guide tube 3. The first adjustment bolt 1 is screwed so that the top of the linked first adjustment bolt 1 moves against the wedge block 32 at the center position of the guide tube 3, thereby separating the rubber pad adhered to the bottom of the general cap from the flange surface of the casing oil pillow.

[0025] The adjustment assembly includes: a first linkage block 27 that can move back and forth up and down along the support seat 28 of the clamp 7, a guide nut 30 fastened to the clamp 7, an abutment member 31 connected to the bottom of the first linkage block 27, a first connecting member 26 connected to the top of the first linkage block 27, a second connecting member 23 connected to the first connecting member 26, a second linkage block 24 sleeved in the second connecting member 23, and a second adjustment bolt 29.

[0026] The end of the second adjusting bolt 29 is installed in the abutment 31 and guided by the guide nut 30. The second adjusting bolt 29 is screwed and drives the first linkage block 27 to move up and down along the clamp 7. The first linkage block 27, the first connecting member 26 and the second connecting member 23 are linked in sequence.

[0027] The position of the second linkage block 24 in the second connecting member 23 is adjusted so that the linkage adjustment positions the center of the operation circle for detaching the general cap from the assembly.

[0028] In specific implementation, the clamp 7 is set to be two pieces, and it is fastened to the casing oil pillow by four third fastening screws 5 respectively. Before fastening, the position needs to be adjusted to ensure that the four wedge blocks 32 avoid the casing oil pillow flange screws in the direction of movement toward the center of the circle, and the bottom planes of the four wedge blocks 32 are close to the casing oil pillow flange surface. Then the first adjustment bolt 1 is screwed clockwise, so that the first adjustment bolt 1 moves toward the center of the circle with the cooperation of the guide nut 2, and the top of the first adjustment bolt 1 pushes the wedge block 32 toward the center of the circle at the center position of the guide tube 3. Under the balanced force of the four wedge blocks 32, the pine rubber pad adhered to the bottom flange of the general cap is separated from the flange surface of the oil pillow, so that the general cap is detached.

[0029] Furthermore, a pin 33 is disposed across the tail of the wedge block 32, and the rubber pad stripping member also includes: a first spring 4, the opposite ends of which respectively abut against the pin 33 and the side walls of the clamp 7, wherein: the first spring 4 abuts against the pin 33 to link the wedge block 32 to move linearly along the guide tube 3 for reset.

[0030] The guide tube 3 is provided with a guide groove 6 for guiding the pin 33 ; a guide nut 2 is installed at the end of the guide tube 3 , and the first adjusting bolt 1 is adaptively connected to the guide nut 2 .

[0031] During implementation, the first adjusting bolt 1 is loosened counterclockwise. Since the pin 33 crosses the tail of the wedge block 32, under the rebound force of the first spring 4, the pin 33 moves linearly along the guide groove 6 to drive the wedge block 32 to move linearly in the guide tube 3, and finally returns to the initial state. It should be noted that the cross-sectional size of the wedge block 32 is highly matched with the inner cavity size of the guide tube 3, and the gap is small, so as to avoid the wedge block 32 from moving toward the center of the circle and causing the output force to shift.

[0032] Preferably, the rubber pad peeling pieces are four evenly arranged.

[0033] During implementation, after the sleeve separates the rubber ring on the flange surface of the general cap, the second adjustment bolt 29 is rotated, and the screw passes through the abutment 31 and cooperates with the guide nut 30, driving the first linkage block 27 to move up and down through the support seat 28, and the two first fastening screws 25 fix the first connecting member 26 and the first linkage block 27, thereby driving the first connecting member 26 and the second connecting member 23 to move up and down synchronously. The second linkage block 24 penetrates the second connecting member 23, and the matching clearance is small, and its main function is to adjust the rotation part linkage column 19 to overlap the center of the general cap terminal. Then tighten the second fastening screw 22.

[0034] Preferably, the moving direction of the second linkage block 24 along the second connecting member 23 is perpendicular to the moving direction of the first linkage block 27 along the clamp 7 .

[0035] Furthermore, the general cap detaching assembly includes: a circular column 18; a hexagonal head 8 and a linkage column 19 which are sleeved in the circular column 18 and connected as a whole; a first clamp 34 connected to the linkage column 19; and a detachable second clamp 20 connected to the first clamp 34, wherein: one end of the circular column 18 is fastened to the adjustment assembly, and the hexagonal head 8 and the linkage column 19 which are connected as a whole are sleeved with a second spring 15 and a plane thrust ball bearing 16, and the hexagonal head 8 presses against the second spring 15 and the plane thrust ball bearing 16 on the circular column 18, wherein: the general cap terminal is clamped by the first clamp 34 and the second clamp 20, and the general cap is detached by screwing the hexagonal head 8 and the linkage column 19.

[0036] The function of the second spring 15 is: in addition to giving a signal for removing the general cap, it also plays a buffering role. Because the threaded columns of the sleeve lead-out wire of the general cap are two copper materials, if there is no spring buffer, the general cap will be rotated under mechanical stress, which will easily damage the inner thread of the general cap and the sleeve lead-out wire thread, which will easily cause the thread gap to increase after reinstallation, and the gap discharge will easily cause heat.

[0037] Furthermore, the general cap detachment assembly also includes: a first connecting seat 10 fastened to the hexagonal head 8 and a second connecting seat 17 fastened to the circular column 18, the first connecting seat 10 is equipped with a magnet 11, and the second connecting seat 17 is respectively equipped with an electronic counter 14 and a magnetic induction sensor 12, wherein: the magnet 11 and the magnetic induction sensor 12 are arranged opposite to each other, the magnet 11 rotates with the first connecting seat 10 and triggers the counting data of the magnetic induction sensor 12 to be displayed on the electronic counter 14.

[0038] Among them, the magnet 11 is connected with an adjusting screw 9, which is installed on the first connecting seat 10, and the second connecting seat 17 is provided with a connecting nut 13, and the magnetic induction sensor 12 is adaptively connected with the connecting nut 13, wherein: the magnet 11 and the magnetic induction sensor 12 are adjusted by the screw 9 to meet the spacing distance of 0-20mm.

[0039] Preferably, a fastening screw 21 is provided between the first clamp 34 and the second clamp 20 .

[0040] During implementation, the circular column 18 is welded to the second linkage block 24, and the hexagonal head 8 and the linkage column 19 are integrated and penetrate the second spring 15, the plane thrust ball bearing 16, the circular column 18 and the first hoop 34 from top to bottom. In addition, the first connecting seat 10 is welded to the linkage column 19. The second connecting seat 17 is welded to the circular column 18. The adjustment screw 9 is installed on the first connecting seat 10, and the magnet 11 at the top of the adjustment screw 9 is adjusted. The gap between the magnet 11 and the magnetic induction sensor 12 is changed by rotating the adjustment screw 9. When the linkage column 19 overlaps with the center of the general cap, the four fastening screws 21 are tightened to clamp the second hoop 20 and the first hoop 34 to clamp the general cap terminal, and then the second adjustment bolt 29 is adjusted to lift the entire general cap. Under the gravity of the general cap, the second spring 15 will be compressed, that is, the distance between the first connecting seat 10 and the second connecting seat 17 will be reduced, so it is necessary to adjust the adjustment screw 9 so that the distance between it and the sensor is within the specified range.

[0041] The magnetic induction sensor 12 is fixed on the second connecting seat 17 with a connecting nut 13, and the electronic counter 14 is installed on the second connecting seat 17. When the general's cap rotates one circle, the magnet 11 also rotates one circle with the first connecting seat 10, triggering the magnetic induction sensor 12 to count once and display it on the electronic counter 14, wherein: the function of the plane thrust ball bearing 16 is to reduce the friction between the second spring 15 and the annular column 18.

[0042] When the disassembly device for the general cap of the transformer high-voltage bushing in this embodiment is implemented, first, the two clamps 7 are fastened to the bushing oil pillow through the four third fastening screws 5. The position needs to be adjusted before fastening to ensure that the four wedge blocks 32 avoid the bushing oil pillow flange screws in the direction of movement toward the center of the circle, and the bottom planes of the four wedge blocks 32 are close to the bushing oil pillow flange surface.

[0043] Then, screw the four first adjustment bolts 1 clockwise, so that the first adjustment bolts 1 move toward the center of the circle with the cooperation of the guide nut 2, and the top of the first adjustment bolt 1 pushes against the wedge block 32 at the center of the guide tube 3 and moves toward the center of the circle. Under the balanced force of the four wedge blocks 32, the rubber pad adhered to the flange of the general cap bottom is separated from the flange surface of the oil pillow, so that the general cap is detached. Then, loosen the first adjustment bolt 1 counterclockwise, and under the rebound force of the first spring 4, the pin 33 moves linearly along the guide groove 6 to drive the wedge block 32 to return to the initial state.

[0044] Further, the second adjusting bolt 29 is screwed to adjust the height of the second clamp 20 and the first clamp 34, and the second linkage block 24 is adjusted so that the second clamp 20 and the first clamp 34 are concentric with the general terminal, and the two second fastening screws 22 are tightened to fix the second linkage block 24, and the four fastening screws 21 are tightened to clamp the general cap terminal. Then, the second adjusting bolt 29 is screwed again to make the distance between the general cap flange surface and the top flange surface of the oil pillow 2-3mm, at this time the second spring 15 is compressed, and the adjusting screw 9 is adjusted to make the magnet 11 and the magnetic induction sensor 12 meet the distance of 0-20mm, and then the hexagonal head 8 is rotated counterclockwise for several turns until the second spring 15 is suddenly released, the general cap is detached, and the number on the electronic counter 14 is read. In other embodiments, after loosening the four fastening screws 21, the general cap is removed for defect elimination or replacement, and the process is reversed when reinstalling.
