Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, and in particular to a self-cooling dry-type transformer. Background Art

[0002] Dry-type transformers are transformers whose cores and windings are not immersed in insulating oil, and they are cooled by air convection and other methods. This type of transformer is flame-retardant, fire-resistant, explosion-proof and environmentally friendly, safe and reliable to use, and easy to install and maintain. Therefore, it can penetrate deep into the load center and is widely used in high-rise buildings, subways, railway stations, airports, hospitals, petrochemical enterprises, and mines.

[0003] At present, in the prior art, a Chinese patent with announcement number CN220252990U discloses a self-cooling dry-type transformer. The device can drive the small gear to rotate through the rotating rod after the motor is started, and the large gear can drive the first iron ring and the second iron ring to rotate through the arrangement of the first iron ring, the first inclined plate, the second iron ring and the second inclined plate. At this time, through the arrangement of the first inclined plate and the second inclined plate, the hot flow gas around the transformer can be discharged, so that the hot gas around the transformer is reduced, and the surrounding temperature is reduced, so that the transformer can quickly transfer the temperature. However, in actual use, the iron ring on the outer wall of the dry-type transformer will produce friction with the base when rotating, which may not only lead to increased mechanical wear, but also pose a potential threat to the stable operation of the transformer. It is more noteworthy that when the iron ring stops rotating, it may reverse due to inertia, which further increases the possibility of friction and wear, thereby affecting the service life and performance of the transformer. In view of this, we propose a self-cooling dry-type transformer. Utility Model Content

[0010] Preferably, a sliding groove is provided in the slide rail, a spring 1 is fixedly connected to the sliding groove, and the sliding groove is elastically connected to the extrusion block through the spring 1. When the iron ring runs in the forward direction, the protrusion fits against the outer wall of the extrusion block and passes through directly and quickly. When the iron ring stops rotating, it may reverse due to inertia. At this time, the raised edge of the extrusion block blocks the moving protrusion to avoid reversal.

[0011] Preferably, the sliding groove is connected to the connecting groove, and the connecting groove is opened inside the base. A movable component is slidably connected between the sliding groove and the connecting groove. The movable component is fixedly connected to the extrusion block.

One end of the connecting plate is arranged below the movable component, and the other end of the connecting plate is arranged below the lubricating grease. The connecting plate is squeezed during the downward pressing process of the limit column. One end of the connecting plate was originally tilted up by the pressure of the lubricating grease. At this time, the lubricating grease is lifted up after being squeezed, so as to lubricate the components in contact during sliding to prevent friction and wear.

[0015] The working principle and beneficial effects of the utility model are:

[0016] 1. In the utility model, a plurality of connecting rods are rotated in the slide rails by means of a rotating direction-adjusting device, driving the sleeved inclined plates to flip and realize self-cooling performance. When the iron ring is running in the forward direction, the protrusion fits the outer wall of the extrusion block and passes through directly and quickly. When the iron ring stops rotating, it may reverse due to inertia. At this time, the raised edge of the extrusion block blocks the moving protrusion to avoid the reverse phenomenon. At the same time, the lubrication function is realized through the effect of the extrusion block and the subsequent linkage effect.

The rotating direction adjustment device 8 is movably connected with a lubrication component 9, and the rotating direction adjustment device 8 includes a slide rail 81.

[0029] Example 1

[0030] like Figure 2~Figure 6As shown, in order to prevent the iron ring 82 from reversing due to inertia after it stops rotating, the present embodiment specifically has a slide rail 81 on the outer wall of the base 1, and the iron ring 82 is slidably connected to the slide rail 81 through a connecting rod 83 that penetrates therethrough, one end of the connecting rod 83 is rotatably connected to an inclined plate 84, and the other end of the connecting rod 83 is fixedly connected to a protrusion 85, and multiple groups of protrusions 85 are provided, and the arrangement of multiple groups of connecting rods 83 assists in the stability of rotation, drives the sleeved inclined plate 84 to flip and realize self-cooling performance, and a slide groove 86 is provided in the slide rail 81, and a spring 87 is fixedly connected to the slide groove 86, and the slide groove 86 is elastically connected to the extrusion block 88 through the spring 87, and when the iron ring 82 is running forward, the protrusion 85 fits with the outer wall of the extrusion block 88 and passes directly and quickly, and when the iron ring 82 stops rotating, it may reverse due to inertia. The reversal phenomenon occurs. At this time, the raised edge of the extrusion block 88 blocks the moving protrusion 85 to avoid the reversal phenomenon. The sliding groove 86 is connected to the connecting groove 810, and the connecting groove 810 is arranged inside the base 1. The sliding groove 86 and the connecting groove 810 are slidably connected with a movable component 89. The movable component 89 is fixedly connected to the extrusion block 88. When the extrusion block 88 is squeezed, the movable component 89 is driven to achieve the subsequent lubrication effect. The movable component 89 includes a sliding column 891. A movable rod 893 is slidably connected in the through cavity of the sliding column 891. The outer wall of the movable rod 893 is fixedly connected to a limiting column 894. The limiting column 894 is slidably connected in the oblique groove 892 of the through cavity. After the extrusion block 88 is squeezed, the sliding column 891 is driven to move backward. The limiting column 894 in the sliding column 891 can only do lifting and lowering movements under the limitation of the vertical groove body.

[0032] Example 2

[0033] like Figure 7As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes to significantly reduce the friction coefficient of movement, extend the service life of the iron ring 82 and the base 1, and improve the use efficiency of the self-cooling dry-type transformer. Specifically, the lubrication component 9 includes a circular groove 91, which is opened in the slide rail 81, and the circular groove 91 is connected to the connecting groove 810. A lubricating paste 94 is arranged in the circular groove 91. The lubricating paste 94 is mainly used to reduce the friction and wear between the various components of the dry-type transformer self-cooling device during operation, thereby protecting the dry-type transformer, extending the service life, reducing the lubrication interval, and reducing the maintenance cost. A spring 2 93 is fixedly connected in the connecting groove 810, and the spring 2 93 is fixedly connected to a connecting plate 92. One end of the connecting plate 92 is arranged below the movable component 89, and the other end of the connecting plate 92 is arranged below the lubricating paste 94.

When the iron ring 82 is running forward, the protrusion 85 fits the outer wall of the extrusion block 88 and passes directly and quickly. When the iron ring 82 stops rotating, it may reverse due to inertia. At this time, the protrusion of the extrusion block 88 The edge of the raised block 85 blocks the movement to avoid reversal. While the extrusion block 88 moves inward, it drives the fixedly connected sliding column 891 to move backward. The limiting column 894 in the sliding column 891 can only do lifting and lowering movements due to the limitation of the vertical groove body. During the downward pressing process, the limiting column 894 squeezes the connecting plate 92. One end of the connecting plate 92 was originally tilted up by the pressure of the lubricating paste 94. At this time, after being squeezed, the lubricating paste 94 is lifted up to lubricate the components in contact during sliding to prevent friction and wear.
