Description

Technical Field

[0001] The invention relates to the technical field of transformer bushings, and in particular to an intelligent dust removal device for transformer bushings. Background Art

[0002] The transformer bushing is the main insulation device outside the transformer box. The lead wires of the transformer winding must pass through the insulating bushing to insulate the lead wires and the lead wires from the transformer casing to ensure electrical safety. The transformer bushing has the important task of leading the high and low voltage leads inside the transformer to the outside of the oil tank.

[0003] At present, the existing transformers are exposed to the air for a long time, which will absorb a lot of dust and debris. These dusts will be deposited on the surface of the transformer bushing to form a thick dust layer. When there is a large dust layer on the outside of the transformer bushing, on the one hand, the transformer bushing will cause partial discharge in a humid environment, and even cause a short circuit fault. On the other hand, the long-term accumulation of dust layers will reduce the insulation strength of the transformer bushing, making the equipment more susceptible to voltage shocks during normal operation, thereby damaging the insulation structure.

[0059] An arc-shaped positioning plate 424 is fixedly mounted on one end of the push bolt 422 located at the sliding opening 12, and the positioning plate 424 fixes the two slide blocks 41 inside the sliding opening 12;

[0060] A connecting seat 43 is installed on the slider 41 and located inside the sliding opening 12. A connecting rod 44 is hinged on the connecting seat 43 through a pin shaft. One end of the two connecting rods 44 is rotatably connected to a support shaft 45.

[0061] The two ends of the support shaft 45 are fixedly connected with support plates 46, and a clamping plate 47 is fixedly connected between the two support plates 46. The clamping plate 47 is arc-shaped, and the inner side thereof is provided with anti-slip grooves, so that when the two clamping plates 47 are fixed on the transformer bushing, they are fixed to the base of the transformer bushing through the two clamping plates 47;

[0062] Both ends of the clamping plate 47 are connecting ends 471 , and a fastener 48 is connected between the two clamping plates 47 via the connecting ends 471 .

[0063] The fastener 48 includes a fastening bolt 481 threadedly connected to two connecting ends 471 at one end of the two clamping plates 47, wherein a locking nut 482 is provided at the connecting end 471 of one clamping plate 47, and the locking nut 482 is threadedly connected to the fastening bolt 481;

[0064] Specific implementation process: When the dust removal mechanism is fixed, the two clamping plates 47 are moved to the base of the transformer bushing respectively, and the two supporting shells 1 are aligned with each other, that is, the two ends of the two semi-circular bottom plates 2 at the supporting shell 1 are aligned.

[0065] Then, the two clamping plates 47 are pulled respectively, and the two clamping plates 47 are tightly attached to the base of the transformer bushing. Then, the connection ends 471 of the two clamping plates 47 are fastened with the fastening bolts 481 to each other.

When the rotating plates 423 rotate, the corresponding pushing bolts 422 are further rotated. Because the pushing bolts 422 are limited by the positioning plate 424, the positioning plate 424 further fixes the two moved sliders 41. At this time, the two supporting shells 1 can be fixed to each other on the outside of the transformer bushing.

[0066] The rotating mechanism 5 is installed at the two supporting shells 1, and the outer sides of the two semi-circular bottom plates 2 are respectively provided with gear grooves, and the two supporting shells 1 are provided with rotating ports 13.

The driven gear 52 is rotatably connected with the corresponding supporting shell 1 through a rotating shaft. A rotating shaft 53 is fixedly installed on the inner ring of the driving gear 51, and a connecting plate 54 is provided at a position corresponding to the rotating shaft 53 of one of the supporting shells 1. A rotating motor 55 for driving the rotating shaft 53 is installed on the connecting plate 54, so that the driving gear 51 is rotated by the operation of the rotating motor 55. When the driving gear 51 rotates, it meshes with the gear groove on the outer side of the semi-circular bottom plate 2, thereby causing the two semi-circular bottom plates 2 to rotate relative to the two supporting shells 1.

[0067] A fixing plate 6, wherein two fixing plates 6 are provided, and the two fixing plates 6 are respectively fixedly mounted on one side of the two semi-circular bottom plates 2 and are located outside the supporting shell 1;

[0068] The dust removal mechanism 7 is installed on the fixing plate 6 and is used to remove dust on the outside of the transformer bushing.

[0069] The ash removal mechanism 7 includes two lifting screw rods 71 ​​rotatably connected to the fixed plate 6, and a synchronous member 72 for synchronously driving the two lifting screw rods 71 ​​is installed on the fixed plate 6. In this embodiment, the synchronous member 72 is two synchronous gears 721 respectively installed on one end of the two lifting screw rods 71 ​​located on the fixed plate 6, and a synchronous belt 723 is connected between the two synchronous gears 721. A synchronous motor 722 for driving one of the synchronous gears 721 is installed on the fixed plate 6, so that the two synchronous gears 721 are synchronously driven by the synchronous belt 723 through the operation of the synchronous motor 722, so that the two lifting screw rods 71 ​​rotate synchronously relative to the fixed plate 6. When the lifting screw rod 71 rotates, it provides a synchronous driving force for the lifting plate 73 thereon, thereby causing the lifting plate 73 to move along the two lifting screw rods 71;

[0070] A lifting plate 73 is rotatably connected between the two lifting screw rods 71, a telescopic member 74 is installed on one side of the lifting plate 73, and an arc-shaped arc shell 75 is connected to the connecting end 471 of the telescopic member 74;

[0071] A plurality of insulating cleaning bristles 76 are disposed on the inner side of the arc shell 75, a hollow cavity is disposed inside the arc shell 75, and a plurality of through holes 751 are disposed on the inner side of the arc shell 75, and the plurality of through holes 751 and the plurality of insulating cleaning bristles 76 are alternately distributed;

[0072] An air supply mechanism 77 for supplying air to the hollow cavity is installed on the fixed plate 6. The air supply mechanism 77 includes a small high-pressure blower 771 installed on the fixed plate 6. The output end of the small high-pressure blower 771 is connected to a first telescopic tube 772. One end of the first telescopic tube 772 is connected to a positioning tube 773. The positioning tube 773 passes through the lifting plate 73. The end of the positioning tube 773 located outside the lifting plate 73 is connected to a second telescopic tube 774. The second telescopic tube 774 is connected to the arc shell 75.

[0073] A groove is provided at the bottom of the lifting plate 73 and at a position corresponding to the telescopic member 74. The telescopic member 74 includes a bidirectional threaded screw 741 installed in the groove. A handle 742 for driving the bidirectional threaded screw 741 is installed at one end of the outer side of the lifting plate 73.

[0074] Two moving blocks 743 are threadedly connected at the bidirectional threaded screw 741, and the two moving blocks 743 slide through the bottom of the groove, and one end of the two moving blocks 743 is installed with a moving seat 744, and the moving seat 744 is hinged with a first positioning support rod 745 through a pin shaft, and the two first positioning support rods 745 are cross-distributed, and the two first positioning support rods 745 are hinged through a pin shaft, and the end of the first positioning support rod 745 away from the moving seat 744 is hinged with a second positioning support rod 746 through a pin shaft;

[0075] The two second positioning rods 746 are crossed and distributed, and one end of the two second positioning rods 746 is hinged to the limit seat 747 through a pin shaft, and the limit seat 747 is fixedly connected to the limit block 748, and the two limit blocks 748 slide through the limit rod 749, and the limit rod 749 is fixedly installed at the bottom of the arc shell 75;

[0076] When it is necessary to remove dust from transformer bushings of different models and sizes, the distance between the two arc-shaped shells 75 is adjusted in advance, even if the multiple insulating cleaning bristles 76 at the two arc-shaped shells 75 are located on the outside of the transformer bushing and in close contact with it, that is, by turning the handle 742, the bidirectional threaded screw 741 is rotated, and when the bidirectional threaded screw 741 rotates, it provides driving forces in opposite directions to the two moving blocks 743 thereon, and at the same time, the moving blocks 743 are limited by the groove, so that the two moving blocks 743 move in opposite directions, and when the moving blocks 743 move, the first positioning support rod 745 thereon is driven to rotate through the moving seat 744, and at the same time, when the two first positioning support rods 745 rotate, the two second positioning support rods 746 thereon are rotated, thereby further realizing the function of adjusting the distance between the two arc-shaped shells 75.

[0077] A scraping detection mechanism 78 is installed on the top of the arc shell 75. The scraping detection mechanism 78 is used to scrape large particles of dust at the transformer bushing. The scraping detection mechanism 78 includes a side plate 781 fixedly installed on the arc shell 75. A detection rod 782 is slidably penetrated on the side plate 781. The detection rod 782 is wedge-shaped, and the edge of the porcelain sleeve of the existing transformer bushing is set in an arc shape. Therefore, when the detection rod 782 moves up or down relative to the transformer bushing, the detection rod 782 and the arc-shaped porcelain sleeve edge are in contact. The detection plate 785 contacts the edge, thereby pushing the detection rod 782 to move relative to the side plate 781, thereby not affecting the detection use of the detection rod 782. A contact plate 783 is installed at one end of the detection plate 785 close to the lifting plate 73. Two connecting springs 784 are connected to the contact plate 783. One end of the two connecting springs 784 is fixedly connected to the detection plate 785, and a pressure sensor 786 is connected to the detection plate 785. The pressure sensor 786 is fixedly installed on the side plate 781; a buzzer 787 is installed on the side plate 781.

[0078] Specific implementation process: when the transformer bushing is deashed, the two arc shells 75 are located on the outside of the bushing, and the insulating cleaning bristles 76 are in close contact with the porcelain sleeve at the bushing, and the driving gear 51 drives the two semi-annular bottom plates 2 to rotate relative to the supporting shell 1 by rotating the motor 55. When the semi-annular bottom plate 2 rotates, the multiple insulating cleaning bristles 76 on the arc shell 75 receive centrifugal force, so as to fully clean and deash the outside of the bushing. At the same time, the small high-pressure blower 771 located on the semi-annular bottom plate 2 is operated, so that the pressurized gas passes through the first telescopic tube 772 and the positioning tube 773 in turn into the hollow cavity inside the arc shell 75, and finally overflows from the multiple through holes 751, so as to achieve the effect of high-pressure blowing of the dust on the outside of the bushing, thereby ensuring that the transformer bushing is fully deashed.

[0079] While the two semi-circular bottom plates 2 rotate, the synchronous member 72 located at the semi-circular bottom plate 2 operates, so that the lifting plate 73 drives the arc-shaped shell 75 thereon to move along the outer side of the transformer bushing, so as to achieve the effect of fully removing dust from the bushing by the multiple edge cleaning bristles;

[0080] Since the synchronization parts 72 at the two semi-annular bottom plates 2 operate synchronously, the detection rod 782 moves synchronously when the arc shell 75 moves. When the pressure sensors 786 at the two detection rods 782 detect a deviation in the signal value, damage is detected at the edge of the transformer bushing. At this time, the buzzer 787 issues an alarm to give a prompt.

[0081] Embodiment 2

[0082] See also Figure 7 Embodiment 2 is a further supplementary explanation of embodiment 1, specifically: of the two semi-annular bottom plates 2, two ends of one of the semi-annular bottom plates 2 are provided with connecting grooves, and a metal iron sheet 21 is installed inside the connecting groove, and two ends of the other semi-annular bottom plate 2 are installed with magnets 22, so that when the two semi-annular bottom plates 2 are connected, they are magnetically connected to each other through the metal iron sheet 21 and the magnet 22, thereby ensuring the rotation of the two semi-annular bottom plates 2 relative to the supporting shell 1, and at the same time ensuring the stability of the rotation of the two semi-annular bottom plates 2.
