[0002] A high impedance three-phase rectifier transformer is a special transformer characterized by its high impedance and three-phase rectification function. High impedance refers to a transformer whose short-circuit voltage percentage exceeds the percentage specified in the national standard for the same voltage level and capacity. This helps to limit the short-circuit current and improve the stability and safety of the system. The three-phase rectifier is a structure that can process three-phase AC power and convert it into DC power.

[0003] The bottom of the existing high-impedance three-phase rectifier transformer is generally provided with a pair of C-shaped channel steels as a bottom support structure to ensure that the transformer is stably and safely installed in the designated position, and to allow a gap between the bottom of the transformer and the ground, so as to facilitate the heat dissipation of the high-impedance three-phase rectifier transformer and reduce the impact of water accumulation on the transformer in rainy and snowy conditions. However, when the high-impedance three-phase rectifier transformer is installed outdoors, debris is easily introduced between the pair of C-shaped channel steels at the bottom of the transformer, thereby affecting the heat dissipation of the bottom of the transformer, and these debris are easily damp and corroded, thereby easily causing corrosion to the bottom components of the transformer.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5As shown, a high-impedance three-phase rectifier transformer described in an embodiment of the utility model includes a transformer housing 1; a partition plate 12 is fixedly connected to the inner bottom of the transformer housing 1; a pair of fixed seats 13 are fixedly connected to the bottom of the transformer housing 1; a reciprocating screw 14 is rotatably connected to the middle of the pair of fixed seats 13; a motor 15 is fixedly connected to the inner bottom of the transformer housing 1; the output end of the motor 15 extends into the interior of a fixed seat 13 and is driven and matched with the reciprocating screw 14 through a bevel gear; a moving seat 16 is threadedly connected to the middle of the reciprocating screw 14; a pair of slide rails 17 are symmetrically arranged and fixed to the bottom of the transformer housing 1; a cleaning assembly 18 is slidably connected to the middle of the pair of slide rails 17; the cleaning assembly 18 is connected to the moving seat 16 The cleaning assembly 18 includes a cleaning plate 23; when working, the motor 15 is started, and the reciprocating screw 14 is driven to rotate through the gear cooperation between the motor 15 and the reciprocating screw 14, so that the moving seat 16 reciprocates along the middle of the reciprocating screw 14, and then drives the cleaning assembly 18 to slide back and forth along the middle of the slide rail 17. At this time, the cleaning plate 23 will push out the debris between a pair of supporting steels at the bottom of the transformer housing 1 when moving, thereby reducing the accumulation of debris between the bottom of the transformer housing 1 and the ground. Through the above structure, the debris at the bottom of the transformer can be cleaned, thereby reducing the impact of the accumulation of debris at the bottom of the transformer on the heat dissipation, and reducing the corrosion of components caused by the accumulation of wet debris.

[0024] like Figures 1 to 5As shown, the cleaning assembly 18 includes a pair of sliding frames 2; the pair of sliding frames 2 are respectively slidably connected to the middle of a pair of slide rails 17; the side walls of the sliding frame 2 are fixedly connected to the middle of the moving seat 16; the middle of the sliding frame 2 is slidably connected with a slider 21; both sides of the slider 21 are fixedly connected with springs 22; the other ends of a pair of springs 22 are respectively fixedly connected to the inner sides of the sliding frame 2; a cleaning plate 23 is fixedly connected to the middle of a pair of sliders 21; a plurality of magnets 24 are evenly distributed and fixedly connected at the bottom of the transformer housing 1; the top of the cleaning plate 23 is made of magnetic material; when working, the sliding frame 2 will slide along the middle of the slide rail 17 with the movement of the moving seat 16, and drive the cleaning plate 23 to move during the sliding of the sliding frame 2. When the cleaning plate 23 moves to a magnet 24 When the moving seat 16 moves below the cleaning plate 23, the top of the cleaning plate 23 will be attracted by the magnet 24, thereby causing a pause and causing the pair of springs 22 to be compressed and stretched respectively. As the moving seat 16 continues to move, the pair of springs 22 will continue to be compressed and stretched respectively. When the suction force between the magnet 24 and the cleaning plate 23 is not enough to counterbalance the elastic force of the pair of springs 22, the cleaning plate 23 will detach from under the magnet 24 and move quickly under the elastic force of the pair of springs 22, thereby pushing out the debris at the bottom of the transformer housing 1, and the impact force will push the debris away from the transformer. Through the above structure, it is difficult for the debris to accumulate near the transformer after being pushed away from the bottom of the transformer housing 1, thereby reducing the occurrence of accumulated debris entering the bottom of the transformer housing 1 again, thereby improving the cleaning effect of the bottom of the transformer housing 1.

[0025] like Figures 1 to 5 As shown, elastic membrane sleeves 3 are fixedly connected to both sides of the movable seat 16; the other ends of a pair of elastic membrane sleeves 3 are respectively fixedly connected to the side walls of a pair of fixed seats 13; a plurality of fixing rings 31 are fixedly connected to the middle of the elastic membrane sleeve 3; when working, the pair of elastic membrane sleeves 3 will shrink or pull the rope as the movable seat 16 moves, while blocking dust and other impurities outside, so that it is difficult for impurities to fall on the surface of the reciprocating screw rod 14. Through the above structure, the occurrence of impurities falling on the surface of the reciprocating screw rod 14 can be reduced, thereby reducing the occurrence of jamming of the movable seat 16.

[0026] like Figures 1 to 4 As shown, a liquid injection tube 4 is fixedly connected to the side wall of the fixed seat 13; a through hole 41 is opened on the side wall of the fixed seat 13; the through hole 41 connects the interior of the elastic membrane sleeve 3 with the interior of the fixed seat 13; during operation, when the transformer is maintained, part of the lubricating liquid can be injected into the interior of the fixed seat 13 through the liquid injection tube 4, and part of the lubricating liquid will enter the interior of the elastic membrane sleeve 3 through the through hole 41, so that part of the reciprocating screw 14 is immersed in the lubricating liquid, so that the movement of the movable seat 16 remains smooth, thereby improving the service life of the component.

[0027] like Figures 1 to 4 As shown, a pair of fixing seats 13 are fixedly connected with fixing rods 5 in the middle; the fixing rods 5 are located inside a plurality of fixing rings 31, and a plurality of fixing rods 5 are arranged above the reciprocating screw rod 14, and a plurality of fixing rods 5 are arranged through the movable seat 16; during operation, when the elastic membrane sleeve 3 contracts due to the movement of the movable seat 16, the plurality of fixing rings 31 will approach each other and slightly fall down on the top of the fixing rods 5, so that the elastic membrane sleeve 3 after contraction is difficult to contact the reciprocating screw rod 14, thereby reducing the occurrence of damage to the elastic membrane sleeve 3 due to friction.

[0028] like Figure 1 to Figure 2 As shown, a plurality of ventilation slots 6 are provided at the bottom of the transformer housing 1; a plurality of fans 61 are installed at the bottom of the partition plate 12; when working, the plurality of fans 61 are started to drive the airflow inside the transformer housing 1 to move quickly, so that part of the heat generated during the operation of the transformer is ejected through the plurality of ventilation slots 6, thereby cooling the transformer; at the same time, when the bottom components of the transformer are in a wet state, the ejected hot air will cause the components to dry quickly, thereby reducing the corrosion and oxidation of the components by liquids.

[0029] like Figure 3 As shown, a plurality of fins 7 are fixed to the bottom of the partition plate 12; the plurality of fins 7 are evenly distributed at the bottom of the partition plate 12; through the above structure, the heat exchange effect between the bottom of the transformer and the airflow can be improved, thereby improving the heat dissipation effect of the transformer.

[0030] When working, the motor 15 is started, and the gears between the motor 15 and the reciprocating screw 14 drive the reciprocating screw 14 to rotate, so that the moving seat 16 reciprocates along the middle of the reciprocating screw 14, and then drives the cleaning assembly 18 to slide back and forth along the middle of the slide rail 17. At this time, the cleaning plate 23 will push out the debris between the pair of supporting steels at the bottom of the transformer housing 1 when moving, thereby reducing the accumulation of debris between the bottom of the transformer housing 1 and the ground. The sliding frame 2 will move along the moving seat 16. The cleaning plate 23 is moved along the middle of the slide rail 17, and the cleaning plate 23 is driven to move during the sliding process of the sliding frame 2. When the cleaning plate 23 moves to the bottom of a magnet 24, the top of the cleaning plate 23 is attracted by the magnet 24, thereby causing a pause and causing the pair of springs 22 to be compressed and stretched respectively. As the moving seat 16 continues to move, the pair of springs 22 will continue to be compressed and stretched respectively. When the suction force between the magnet 24 and the cleaning plate 23 is not enough to counteract the elastic force of the pair of springs 22, the cleaning plate 23 will detach from the bottom of the magnet 24 and be pulled back by the pair of springs. The reciprocating screw rod 14 is a kind of reciprocating screw rod 14, and the ... The rod 14 is immersed in the lubricating liquid. When the elastic membrane sleeve 3 shrinks due to the movement of the moving seat 16, the multiple fixed rings 31 will approach each other and slightly fall down on the top of the fixed rod 5, so that the shrunken elastic membrane sleeve 3 is difficult to contact the reciprocating screw rod 14. The multiple fans 61 are started to drive the air flow inside the transformer housing 1 to move quickly, so that part of the heat generated during the operation of the transformer is ejected through the multiple ventilation slots 6, thereby cooling the transformer. At the same time, when the bottom component of the transformer is in a wet state, the ejected hot air will quickly dry the component.
