Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to an energy-saving transformer. Background Art

[0002] Transformers are divided into dry-type transformers and oil-immersed transformers. Dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. Their cooling methods are divided into natural air cooling and forced air cooling. When using natural air cooling, the transformer can operate continuously for a long time at rated capacity. When using forced air cooling, the transformer output capacity can be increased by up to 50%. It is suitable for intermittent overload operation or emergency overload operation.

[0003] In the existing dry-type transformer, when dissipating heat from the interlayer between the inner and outer coils, an air duct is generally reserved inside the interlayer, and air is then sent into the air duct by a fan to dissipate heat from the inner and outer coils on both sides of the interlayer. Since the air duct is connected to the outside, the fan also sends external dust into the air duct while sending air. After long-term use, dust is adsorbed and deposited on the inside of the outer coil and the outside of the inner coil, thereby hindering the heat exchange between the inner and outer coils and the airflow in the interlayer, resulting in a decrease in heat dissipation efficiency and increased energy consumption.

DETAILED DESCRIPTION

[0014] 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.

[0015] The present invention provides Figure 1-Figure 5 An energy-saving transformer shown in the figure includes an upper yoke 100, a lower yoke 110, and an iron core 200. The upper yoke 100 is provided on the front and rear sides of the iron core 200, an inner coil 210 is provided at the lower end of the iron core 200, an outer coil 220 is provided on the periphery of the inner coil 210, a lower yoke 110 is provided at the bottom of the inner coil 210 and the outer coil 220, a lower base 120 is provided below the lower yoke 110, a cooling box 300 is provided on the front and rear sides of each inner coil 210 and the outer coil 220, and a connecting pipe 400 is connected to the center of the bottom of the cooling box 300.

[0016] The cooling box 300 is used to dissipate heat between the outer coil 220 and the inner coil 210 .

[0017] In some specific embodiments of the present invention, an air outlet 310 is provided on the upper rear side of the cooling box 300, a filter plate 320 is provided on the air outlet 310, a cooling box cover 330 is provided on the upper side of the cooling box 300, and a guide plate 340 is provided inside the cooling box 300.

[0018] The air outlet 310 is used to align with the outer coil 220 and the inner coil 210, and the cooling box 300 and the guide plate 340 are arranged to increase the air flow rate of the air outlet 310 and improve the cooling effect.

[0019] In some specific embodiments of the present invention, a motor 500 is provided on the upper part of the connecting tube 400, and the motor 500 is fixed to the inner wall of the connecting tube 400 by two left and right connecting rods 510. A fan blade 520 is provided above the motor 500, and a motor 600 is provided below the motor 500. The motor 600 is fixed to the inner wall of the connecting tube 400 by two left and right connecting rods 610. A screw 620 is connected below the motor 600, and the screw 620 is provided with a slot 630. The slot 630 is connected to a ring 640, and the ring 640 is respectively connected to the four support rods 650 by rotating from top to bottom. 0. Four support rods 660, support rods 650 are connected by fan-shaped plate 1 651, fan-shaped plate 1 651 is provided with a plurality of circular holes 1 652, support rods 2 660 are connected by fan-shaped plate 2 661, fan-shaped plate 2 661 is provided with a plurality of circular holes 2 662, support rods 2 660 and fan-shaped plate 2 661 are connected to one end of elastic cloth 670 at the periphery, the other end of elastic cloth 670 is connected to the inner wall of connecting tube 400, support rods 2 660 are fixedly connected to one end of connecting rod 3 680 at the bottom, the other end of connecting rod 3 680 is rotatably connected to circular ring 2 690, circular ring 2 690 is threadedly connected to screw 620.

[0020] Among them, the function of the slot 630 is to make the ring 1 640 and the screw 620 slidingly connected when the motor 2 600 rotates. When the motor 2 600 rotates, the ring 2 690 is threadedly connected to the screw 620, so the ring 2 690 will rise or fall on the screw 620, thereby driving the connecting rod 3 680 to rotate, and then driving the support rod 2 660 to rotate. The support rod 1 650 acts on the support rod 2 660. When the support rod 2 660 rotates, the support rod 1 will also rotate accordingly. The elastic fabric 670 is configured to fill the gap between the support rod 2 660 and the fan plate 2 661 and the inner wall of the connecting tube 400.

[0021] In some specific embodiments of the present invention, the first circular hole 652 and the second circular hole 662 are of the same size, and when the first support rod 650 and the second support rod 660 are parallel, the first circular hole 652 and the second circular hole 662 correspond in position.

[0022] Among them, when the support rod 1 650 and the support rod 2 660 are parallel, the positions of the circular hole 1 652 and the circular hole 2 662 are corresponding, and the air intake is maximum at this time. When the circular hole 1 652 and the circular hole 2 662 are gradually misaligned, the air intake gradually decreases.

[0023] During use, when the load is at its maximum, the motor 500 can be turned to maximum power, and the support rod 1 650 and the support rod 2 660 can be rotated to be parallel. At this time, the air intake is maximum, and the dust will enter the cooling box 300 through the circular hole 1 652 and be blocked by the filter plate 1 320, and then can be cleaned through the cooling box cover 330. When the power does not need to be turned to maximum, the support rod 2 660 can be rotated to make the circular hole 1 652 and the circular hole 2 662 misaligned, thereby reducing the aperture, which can block finer dust. Since the connecting pipe is arranged vertically on the ground, the dust can fall directly on the ground, avoiding entering the cooling box 300 and causing inconvenience in cleaning.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
