[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0040] It should be understood that the step numbers used in the text are only for convenient description and do not limit the execution sequence of the steps.

[0041] It should be understood that the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0042] The terms "comprising" and "including" indicate the presence of the described features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or their combinations.

[0043] The term " / and" refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0044] In order to solve the problem of transformer noise, in the prior art, either a fully enclosed substation is established, or sound-absorbing materials are attached to the transformer shell, or the transformer structure is optimized to reduce the core magnetic flux density to reduce the transformer noise.

[0045] However, for the first solution, the fully enclosed substation will affect the heat dissipation of the transformer, resulting in a reduction in its heat dissipation capacity, and the enclosed transformer room is not conducive to the installation and maintenance of the transformer; for the second solution, the sound-absorbing materials are not only expensive but also not conducive to the natural air-cooled heat dissipation of the transformer; for the third solution, although the noise can be reduced through the optimized design of the transformer structure, the R & D cycle is too long and the cost is relatively high.

[0046] In view of this, the present invention proposes a transformer noise reduction control device that can effectively balance the problems of noise reduction and heat dissipation and has a lower cost.

[0047] Please refer to Figure 1 , the transformer noise reduction control device provided by an embodiment of the present invention includes a control module 1, and a temperature detection element 2, a noise detection element 3, a heat dissipation module 4 and a sound insulation cover 5 that are respectively connected to the control module 1.

[0048] Among them, the temperature detection element 2 is arranged outside the transformer oil tank for detecting the current temperature of the transformer; the noise detection element 3 is arranged around the transformer for detecting the current noise of the transformer; the sound insulation cover 5 covers the outside of the transformer, and the heat dissipation module 4 is arranged inside the sound insulation cover 5.

[0049] Specifically, the control module 1 is used to adjust the operating state of the heat dissipation module 4 and the opening and closing angle of the top sound insulation barrier plate 54 of the sound insulation cover 5 according to the current temperature and the current noise.

[0050] It can be understood that the control module 1 is arranged in the substation monitoring room.

[0051] Please refer to Figures 2 to 4 . In this embodiment, the sound insulation cover 5 specifically includes a front side sound insulation barrier plate 51, a left side sound insulation barrier plate 52, a right side sound insulation barrier plate 53 and a top sound insulation barrier plate 54. Among them, the front side sound insulation barrier plate 51 is fixedly arranged at the wall-piercing bushing load-bearing wall 6; the top sound insulation barrier plate 54 is symmetrically composed of a left plate and a right plate, and the bottoms of the left plate and the right plate are respectively connected to the tops of the left side sound insulation barrier plate 52 and the right side sound insulation barrier plate 53 through a hydraulic lifting mechanism 7.

[0052] It should be noted that each sound insulation barrier plate of the sound insulation cover 5 is made of sound-absorbing material; the wall-piercing bushing load-bearing wall 6 is of a full-steel structure, with columns made of wide flange hot-rolled H-shaped steel of specification 30 (H = 500) and beams made of narrow flange hot-rolled H-shaped steel (H = 350), and filled with concrete.

[0053] In this embodiment, the device is also provided with a motor control module 8. One end of the motor control module 8 is connected to the control module 1, and the other end is electrically connected to the hydraulic lifting mechanism 7, and is used to control the hydraulic lifting mechanism 7 to lift and lower the left plate and the right plate according to the control signal sent by the control module 1.

[0054] For the detection part, in this embodiment, the temperature detection element 2 includes a plurality of transformer oil tank radiators 21 and a plurality of temperature sensors 22. Among them, a plurality of transformer oil tank radiators 21 are respectively arranged on both sides of the transformer oil tank; a plurality of temperature sensors 22 are respectively fixedly arranged on each of the transformer oil tank radiators 21.

[0055] In another embodiment, a temperature recorder 9 can also be arranged in the substation monitoring room, and the temperature recorder 9 is used to receive the temperature data collected by each temperature sensor 22.

[0056] Exemplarily, two transformer tank radiators 21 can be arranged on both sides of the transformer tank respectively. At the same time, a temperature sensor 22 is fixed on each transformer tank radiator 21 to collect the current temperature of the transformer tank in real time and transmit the temperature value to the temperature recorder 9 and the control module 1.

[0057] In this embodiment, the noise detection element 3 includes a plurality of noise sensors, and each noise sensor is respectively arranged around the front sound insulation barrier plate 51, the left sound insulation barrier plate 52 and the right sound insulation barrier plate 53, and at the upper end of the top sound insulation barrier plate 54, for monitoring the noise value around the transformer in real time and transmitting it to the control module 1 through wireless communication.

[0058] In another embodiment, moving mechanisms 10 are respectively arranged at the bottoms of the left sound insulation barrier plate 52 and the right sound insulation barrier plate 53 to facilitate handling.

[0059] Specifically, the moving mechanism 10 can be set as a suspension and wheels driven by a motor. When large-scale operation and maintenance of the transformer are required, the motor can be driven by the control module 1 to control the movement of the wheels, so as to move the left sound insulation barrier plate 52 and the right sound insulation barrier plate 53 to an open space for the transformer to carry out operation and maintenance.

[0060] The heat dissipation module 4 includes a plurality of blowers, and each blower is respectively installed at the bottom of each transformer tank radiator 21, and can promote the heat dissipation of the transformer by increasing the wind speed.

[0061] In this embodiment, the device further includes a low-voltage winding bushing 11, a medium-voltage winding bushing 12, a high-voltage winding bushing 13 and a high-voltage through-wall bushing 14; wherein, the high-voltage through-wall bushing 14 is fixedly arranged above the through-wall bushing load-bearing wall 6, so that the high-voltage bus is connected to the high-voltage winding bushing 13 through the high-voltage through-wall bushing 14.

[0062] A bushing refers to an insulating device that leads the high, medium and low voltage leads inside the transformer to the outside of the tank, which not only insulates the lead from the ground, but also plays a role in fixing the lead.

[0063] Among them, the high-voltage through-wall bushing 14 is a device for allowing the conductive part to pass through a wall or the tank of electrical equipment such as a transformer or a high-voltage instrument transformer, and fixing the conductive part at the corresponding position.

[0064] It can be understood that when the transformer is operating normally, the temperature remains balanced. At this time, the top sound insulation barrier plate 54 of the sound insulation cover 5 is completely closed, and the overall noise value around the transformer is in a relatively low state.

[0065] When the load of the transformer increases, if the temperature recorder 9 shows that the current temperature is higher than the temperature threshold, the control module 1 controls the hydraulic lifting mechanism 7 to rise through the motor control module 8. At this time, the left and right plates of the top sound insulation barrier plate 54 open at a certain angle, and the wind speed of the blower is increased to form upper and lower heat dissipation channels to promote the heat dissipation of the transformer oil tank.

[0066] Meanwhile, the control module 1 also detects the noise value around the substation through the noise sensor. When the noise value is less than the noise threshold, the opening angle of the top sound insulation barrier plate 54 continues to increase to ensure the expansion of the upper and lower heat dissipation channels until the detected noise value reaches the preset threshold, so as to ensure that the noise value of the transformer does not exceed the noise threshold while the transformer is dissipating heat.

[0067] It should be noted that the noise threshold can be set according to the residential environmental noise pollution standard.

[0068] When the load of the transformer decreases, the temperature of the transformer oil tank also decreases accordingly. If it is detected that the current temperature is lower than the temperature threshold, at this time, the control module 1 controls the hydraulic lifting mechanism 7 to descend through the motor control module 8, so that the top sound insulation barrier plate 54 gradually closes, thereby reducing the noise.

[0069] The component devices of the transformer noise reduction control device provided by the above embodiment of the present invention are simple, low in cost, and can also ensure effective reduction of the transformer noise and stable heat dissipation of the transformer. At the same time, the device is also convenient for the maintenance and replacement of the transformer, and has higher practicability.

[0070] Please refer to Figure 2 , another embodiment of the present invention also provides a transformer noise reduction control method, including the following steps.

[0071] S1: Real-time obtain the current temperature detected by the temperature detection element and the current noise detected by the noise detection element; wherein, the temperature detection element is arranged outside the transformer oil tank, and the noise detection element is arranged around the transformer.

[0072] S2: Adjust the operating state of the heat dissipation module and the opening and closing angle of the top sound insulation barrier plate of the sound insulation cover according to the current temperature and the current noise; wherein, the sound insulation cover covers the outside of the transformer, and the heat dissipation module is arranged inside the sound insulation cover.

[0073] Please refer to Figures 2 to 4 . It should be noted that if the current temperature is greater than the temperature threshold, the heat dissipation module 4 is started and its operating power is increased to promote heat dissipation; if the current temperature is less than the temperature threshold, the heat dissipation module 4 is turned off.

[0074] Specifically, when the current temperature is greater than the temperature threshold: if the current noise is less than the noise threshold, according to the correspondence between the current noise and the opening / closing angle of the top sound insulation barrier plate 54 of the sound insulation cover 5, control the top sound insulation barrier plate 54 to open to the corresponding angle; if the current noise is greater than or equal to the noise threshold, then control the top sound insulation barrier plate 54 of the sound insulation cover 5 to maintain the current opening / closing angle;

[0075] When the current temperature is less than the temperature threshold: control the top sound insulation barrier plate 54 to close.

[0076] The transformer noise reduction control method provided by the above embodiments can not only effectively reduce the noise pollution of the transformer, but also take into account the heat dissipation capacity of the transformer and stabilize the temperature rise of the transformer.

[0077] In a third aspect, an embodiment of the present invention further provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a processor, the transformer noise reduction control method described in any one of the above embodiments is implemented.

[0078] Those of ordinary skill in the art can understand that all or part of the processes of implementing the methods in the above embodiments can be completed by instructing relevant hardware through a computer program. The program can be stored in a computer-readable storage medium. When the program is executed, it can include the processes of the embodiments of the above methods. Among them, the storage medium can be a magnetic disk, an optical disk, a read-only memory (ROM), or a random access memory (RAM), etc.

[0079] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
