TECHNICAL FIELD

[0001] The application belongs to the technical field of transformers, and particularly relates to a dry-type transformer. BACKGROUND

[0002] The dry-type transformer is a kind of transformer, and is widely used in places such as local lighting, high-rise buildings, airports and wharves CNC mechanical equipment. Although the dry-type transformer is mostly installed in a box body in the actual working environment, so as to achieve a better protection effect, the simple box body cannot achieve comprehensive protection effect, and still has some deficiencies in some aspects. For example, the box body cannot prevent birds from nesting on the surface of the box body, and cannot drive away the birds nearby. Birds like to nest on the transformer box body, which may cause a series of problems to the transformer box body. For example, bird nest sundries and bird droppings can cause dust to accumulate on the surface of the transformer box body, affecting the heat dissipation performance of the transformer box body. The twigs and sawdust in the bird nest may shake and enter the box body through the heat dissipation holes on the box body, thereby causing a short circuit fault on the high-voltage equipment. Even the uric acid and sulfur dioxide attached to the bird nest can erode the surface of the transformer equipment, causing insulation breakdown of the equipment. Therefore, a dry-type transformer capable of driving away birds and preventing birds from nesting is needed. SUMMARY

In a normal state, the bird repelling roller is tightly pressed against the arc surface part.

[0005] A plurality of air holes are formed in the arc surface part.

[0006] A plurality of heat dissipation grooves are further formed in the transformer shell, a matching rod is slidably connected to the heat dissipation grooves, a connecting groove is fixed to the matching rod, and a cleaning brush is detachably connected to the connecting groove through bolts.

[0007] A transmission rod is further fixed to the matching rod, a second tension spring is fixed between the matching rod and the transformer shell, a contact head is fixed to the sliding seat, and the contact head can push the transmission rod to slide.

[0019] As Figures 4-5 shown:

[0020] A dry-type transformer comprises a transformer shell 101, an arc surface part 401 connected to the transformer shell 101, a top side of the arc surface part 401 being an arc surface, a sliding seat 301 connected to the transformer shell 101, a bird repelling roller 303 connected to the sliding seat 301, a first compression spring fixed between the sliding seat 301 and the bird repelling roller 303, the bird repelling roller 303 being tightly pressed on the arc surface part 401 in normal state, a first motor fixed to the transformer shell 101, a first lead screw fixed to an output shaft of the first motor, and the first lead screw being threadedly connected with the sliding seat 301.

[0021] A rectangular slot is opened on the transformer shell 101, and a openable door body is connected at the slot position, then the dry-type transformer body is placed in the transformer shell 101, and the door body is closed, thereby shielding the dry-type transformer body. The above operation is a more mature prior art, which will not be described here. After the device is placed in the working position, when the birds in the working environment want to nest on the transformer shell 101, the arc surface part 401 is directly above the transformer shell 101, so that the birds can only land on the arc surface part 401 to complete the nest building. The arc surface on the upper side of the arc surface part 401 makes it difficult for birds to find a flat surface during nest building, so that the bird nest cannot be built stably on the upper surface of the arc surface part 401, thereby avoiding the bird nest building to some extent;

[0022] Meanwhile, the slide 301 can be operated periodically to slide on the transformer shell 101. The bird repelling roller 303 will be constantly driven to slide during the sliding of the slide 301, so that the bird repelling roller 303 will always be attached to the surface of the arc surface part 401 by the elastic force of the first compression spring and move, thereby further driving the birds on the upper surface of the arc surface part 401, further avoiding the birds from nesting on the transformer shell 101, thereby avoiding the bird nest and bird droppings affecting the heat dissipation effect and the twigs and sawdust in the bird nest entering the inside of the transformer shell 101 to cause accidental short circuit or other accidents, and providing a more stable and good working environment for the dry-type transformer body.

[0023] As shown in Figure 4 As shown in

[0024] A plurality of air holes 402 are opened on the arc surface part 401.

[0025] The plurality of air holes 402 are arranged to increase the difficulty of bird nesting, to some extent, to avoid bird nesting, without fully blocking the upper side of the transformer shell 101, thereby reducing the influence of the arc surface part 401 on the normal heat dissipation of the transformer shell 101, and further providing a more stable and good working environment for the dry-type transformer body inside the transformer shell 101.

[0026] As shown in Figures 5-6 As shown in

[0027] Further comprising a plurality of heat dissipation grooves 104 opened on the transformer shell 101, a matching rod 501 is slidably connected on the heat dissipation groove 104, a connecting groove 502 is fixedly connected on the matching rod 501, and a cleaning brush is detachably connected in the connecting groove 502 by bolts.

[0028] The plurality of heat dissipation grooves 104 can further increase the heat dissipation effect of the transformer shell 101, thereby further providing a better working environment for the dry-type transformer body, and the cooperation rod 501 can be periodically operated to slide up and down on the transformer shell 101, thereby driving the cleaning brush fixed on the connecting groove 502 to move up and down, thereby brushing off the dust and impurities blocked in the plurality of heat dissipation grooves 104, thereby long-term maintaining the heat dissipation effect of the plurality of heat dissipation grooves 104.

[0029] Meanwhile, the connecting groove 502 and the cleaning brush are detachably connected by bolts, so that the staff can periodically detach the aging and damaged cleaning brush from the connecting groove 502 for replacement, thereby ensuring long-term dust and impurity brushing effect.

[0030] As shown in Figures 4-6 ,

[0031] Further comprising a transmission rod 503 fixed on the cooperation rod 501, a second tension spring is fixed between the cooperation rod 501 and the transformer shell 101, and a contact head 302 is fixed on the sliding seat 301. The contact head 302 can push the transmission rod 503 to slide.

[0032] During the operation of sliding the sliding seat 301 left and right on the transformer shell 101, thereby making the bird repelling roller 303 reciprocate on the surface of the arc surface part 401, completing the bird repelling operation process, when the contact head 302 slides to the contact position with the transmission rod 503 and continuously moves, the contact head 302 will gradually press the transmission rod 503, because the transmission rod 503 is a bevel rod, thereby making the continuously sliding contact head 302 gradually press the transmission rod 503 to different positions, thereby making the transmission rod 503 gradually drive the cooperation rod 501 to slide downward to different heights, thereby making the cleaning brush on the connecting groove 502 complete a dust and impurity brushing work, the setting of the second tension spring makes the cooperation rod 501 automatically slide upward to the initial position when the sliding seat 301 resets, ensuring the normal operation of the next brushing work, thereby achieving the operation of conveniently driving the cooperation rod 501 to slide, and only the power source driving the sliding seat 301 to move needs to be maintained during daily maintenance and repair of the equipment, thereby reducing the maintenance and operation cost.

[0033] As shown in Figure 1 , Figure 2 , Figure 8 ,

[0034] The mobile rod 201 is slidably connected in the transformer shell 101, a sliding sleeve 203 is slidably connected on the mobile rod 201, a connecting seat 202 is fixedly connected on the sliding sleeve 203, a heat dissipation fan with a power source is detachably connected on the connecting seat 202 through bolts, a second motor is fixedly connected in the transformer shell 101, a second lead screw is fixedly connected on an output shaft of the second motor, the second lead screw is threadedly connected with the mobile rod 201, a third motor is fixedly connected on the mobile rod 201, a third lead screw is fixedly connected on an output shaft of the third motor, and the third lead screw is threadedly connected with the sliding sleeve 203.

[0035] When the dry-type transformer main body normally works in the transformer shell 101, the heat dissipation fan can be started regularly, so that the heat dissipation fan drives air to flow quickly, and the heat dissipation effect of the dry-type transformer main body is further improved, so that a good working environment is provided for the dry-type transformer main body, and the sliding sleeve 203 can be regularly slid on the mobile rod 201, so that the blowing range of the heat dissipation fan is expanded, so that different positions of the dry-type transformer main body are blown and cooled, and the mobile rod 201 can be slid in the transformer shell 101, so that the blowing range of the heat dissipation fan is further expanded, so that the dry-type transformer main body is conveniently and comprehensively cooled.

[0036] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 8 ,

[0037] The plurality of knocking plates 102 are rotatably connected in the transformer shell 101, a plurality of matching plates 103 are fixedly connected in the transformer shell 101, a torsion spring is fixedly connected between each knocking plate 102 and the transformer shell 101, and the mobile rod 201 can drive the knocking plate 102 to rotate.

[0038] When the mobile rod 201 reciprocally slides in the transformer shell 101 during the process of comprehensively cooling the dry-type transformer main body by the heat dissipation fan, the mobile rod 201 can drive the knocking plate 102 to rotate when the mobile rod 201 slides from left to right, so that the knocking plate 102 gradually rotates counterclockwise on the transformer shell 101, the knocking plate 102 can be quickly reset by the torsional force of the torsion spring when the mobile rod 201 is staggered with the knocking plate 102, so that the matching plate 103 closest to the knocking plate 102 is impacted once due to inertia, and the plurality of knocking plates 102 can be sequentially driven to slide and knocked multiple times as the mobile rod 201 continuously slides to the right, so that the transformer shell 101 can regularly emit knocking sound, so that the bird repelling effect is further improved, and the bird repelling effect is improved even when the power source driving the sliding seat 301 fails.

[0039] When the moving rod 201 is reset by sliding from right to left, the moving rod 201 can again knock the plurality of knocking plates 102 to rotate, so that the plurality of knocking plates 102 rotate clockwise, and then again knock the plurality of matching plates 103, and provide space for normal reset of the moving rod 201.

[0040] As shown in Figure 3 ,

[0041] Each of the knocking plates 102 is provided with an auxiliary through slot 105.

[0042] Since the highest point of the moving rod 201 is the sliding sleeve 203 during the sliding operation of the moving rod 201, when the moving rod 201 slides from left to right to accumulate force and knock, if the sliding sleeve 203 is in contact with the moving rod 201, the moving rod 201 can be knocked to slide to a larger angle, thereby increasing the knocking force;

[0043] During the process of moving the rod 201 from left to right to make the plurality of knocking plates 102 accumulate force and knock multiple times, the sliding sleeve 203 can be in the position opposite the plurality of auxiliary through slots 105 most of the time, and then periodically sliding the sliding sleeve 203 to move the sliding sleeve 203 to a position where it can normally contact a certain knocking plate 102, so that a certain knocking plate 102 can have a strong force accumulation and knocking effect, so that the knocking sound emitted by the device is more varied, thereby further improving the bird repelling effect, and avoiding the situation that the bird repelling effect is reduced after the bird stays around the device for a long time and adapts to the unchanged knocking effect.

[0044] Since the moving rod 201 can slide left and right in the transformer shell 101, different knocking plates 102 can have a strong force accumulation and knocking effect, thereby changing the position where the strong force accumulation and knocking effect occurs, further making the knocking sound emitted more varied and improving the bird repelling effect.

[0045] As shown in Figure 1 , Figure 3

[0046] The plurality of auxiliary through slots 105 on the plurality of knocking plates 102 are arranged in a staggered manner.

[0047] The plurality of auxiliary through slots 105 arranged in a staggered manner make it necessary to continuously slide the sliding sleeve 203 along a predetermined track on the moving rod 201 during the sliding of the moving rod 201 if it is desired to continuously make the knocking plate 102 normally accumulate force and knock, rather than strongly accumulate force and knock, which makes it unnecessary to open the transformer shell 101 to determine the sliding condition of the sliding sleeve 203 through the knocking sound when the staff is performing maintenance and repair work on the driving source of the sliding sleeve 203, thereby providing convenience for maintenance operation.

[0048] As shown in Figure 1 ,​

[0049] The transformer shell 101 is fixed with multiple supporting legs on the lower side.

[0050] The multiple supporting legs can provide support for the transformer shell 101, thereby facilitating the stable placement of the transformer shell 101 in the working position.

[0051] As shown in Figure 1 the drawings:

[0052] The cambered surface part 401 is detachably connected to the transformer shell 101 by means of bolts.

[0053] The detachable connection of the cambered surface part 401 to the transformer shell 101 can facilitate the transportation work, and when the cambered surface part 401 is severely corroded by the surrounding environment due to long-term use, the cambered surface part 401 can be detached from the transformer shell 101 by loosening the bolts for replacement.
