Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a noise reduction transformer for wind power generation. Background Art

[0002] Since the flux density of the transformer is less than the saturation flux density of the core, the voltage increase caused by the increase in load is the main reason for the increased vibration of the winding. In order to reduce the vibration noise of the converter transformer, the traditional treatment method is mainly to control the overload rate of the power generation system, but the power generation system is inevitably in high-load operation, so it cannot directly act on the transformer itself. Although the existing technology of independently installing sound-absorbing panels on the side of the transformer can greatly reduce the propagation of noise sources, it cannot be coordinated according to the degree of noise generation. That is, the sound-absorbing structure is still in use when the peak value of the vibration noise does not meet the noise reduction processing requirements. The application method when it is placed on the fins and the side of the winding will also easily affect the conventional heat dissipation effect. Therefore, its coordination during noise reduction application is not ideal. Summary of the invention

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0020] As Figure 1 - Figure 6 As shown in the figure, a noise reduction type transformer for wind power generation according to the present invention includes a fixed tailstock 1, a three-phase winding 2 and heat dissipation fins 3. Two dual-zone switching noise reduction modules 4 are installed between the fixed tailstock 1 and the three-phase winding 2. The dual-zone switching noise reduction module 4 is slidably connected to the bottom of the three-phase winding 2. Two lateral noise reduction enhancement components 5 are arranged between the fixed tailstock 1 and the heat dissipation fins 3. The lateral noise reduction enhancement component 5 is used to switch the sound insulation arrangement surface of the dual-zone switching noise reduction module 4 according to the carrying state of the heat dissipation fins 3. A wind direction auxiliary heat dissipation guiding component 6 is installed on one side of the fixed tailstock 1, and the wind direction auxiliary heat dissipation guiding component 6 and the heat dissipation fins 3 are distributed oppositely.

[0021] In order to solve the problem that the prior art cannot perform collaborative debugging according to the degree of noise generation and the coordination during noise reduction application is not ideal enough, the present invention sets a dual-zone switching noise reduction module 4, a lateral noise reduction enhancement component 5 and a wind direction auxiliary heat dissipation guiding component 6 for bidirectional switching during high-overload noise reduction and low-overload auxiliary shock absorption applications, effectively improving the adaptability during noise reduction application.

[0022] In an optional implementation mode of this embodiment, the dual-zone switching noise reduction module 4 includes a multi-directional folding splint 41, a porous noise reduction partition 42 and a dislocation damping spacer 43. The multi-directional folding splint 41 is embedded in the bottom of the three-phase winding 2. The porous noise reduction partition 42 is fixedly connected to the multi-directional folding splint 41. A number of dislocation damping spacers 43 are arranged between every two adjacent porous noise reduction partitions 42, and the dislocation damping spacer 43 is fixedly connected to the multi-directional folding splint 41.

[0023] In this embodiment, please refer to Figure 2, when in the non-high-frequency noise reduction application state, the multi-directional folding splint 41, the pore noise reduction spacer 42, and the misaligned shock absorption spacer 43 are all folded and stored inside the C-shaped buffer bracket 22. At this time, the misaligned shock absorption spacer 43 is in a misaligned composite state, that is, when the three-phase winding 2 generates low-frequency vibration noise, a buffer structure is formed by the misaligned shock absorption spacers 43 that are interlaced and compounded in the folded state, so that the C-shaped buffer bracket 22 can assist the C-shaped buffer bracket 22 to perform shock absorption and buffering when bearing low-frequency vibration.

[0024] In an alternative embodiment of this embodiment, the lateral noise reduction and enhancement component 5 includes an arrangement surface guiding frame 51, a longitudinal limiting rod 52, and a directional driver 53. The arrangement surface guiding frame 51 is installed at the upper end of the fixed tail frame 1. The number of the longitudinal limiting rods 52 and the directional drivers 53 is two. The longitudinal limiting rods 52 are symmetrically fixed at both ends of the arrangement surface guiding frame 51. The directional driver 53 is slidably connected to the longitudinal limiting rod 52. One end of the multi-directional folding splint 41 is fixedly connected to the directional driver 53.

[0025] In this embodiment, when high-frequency vibration noise is generated, the multi-directional folding splint 41 can be driven by the directional driver 53 to longitudinally climb along the arrangement path of the longitudinal limiting rod 52 until the directional driver 53 reaches the top of the longitudinal limiting rod 52 and then locks and positions, so that the multi-directional folding splint 41 is in an expanded state after being pulled and held on both sides of the three-phase winding 2. In the current state, there is a gap between every two adjacent misaligned shock absorption spacers 43, which does not affect the passage of vibration noise to the pore surface of the pore noise reduction spacer 42, so that the pore noise reduction spacer 42 can cooperate with external noise reduction equipment to synchronously reduce noise.

[0026] In an alternative embodiment of this embodiment, the directional driver 53 is composed of a sliding actuator 531, an electric control lock 532, and an execution control module 533. The electric control lock 532 is sleeved outside the longitudinal limiting rod 52. Both the electric control lock 532 and the execution control module 533 are fixedly connected to the outer shell of the sliding actuator 531. The sliding actuator 531 is used to drive the electric control lock 532 to longitudinally slide along the longitudinal limiting rod 52.

[0027] In an alternative embodiment of this embodiment, the arrangement surface guiding frame 51 is fixedly connected to the C-shaped buffer bracket 22. The arrangement surface guiding frame 51 is provided with a through groove. One end of the multi-directional folding splint 41 penetrates through the through groove opened in the arrangement surface guiding frame 51 and extends to the position of the electric control lock 532. One end of the multi-directional folding splint 41 is fixedly connected to the electric control lock 532.

[0028] In an optional implementation of this embodiment, the signal receiving end of the execution control module 533 is connected to the signal transmission module 11, and the signal transmission end of the execution control module 533 is connected to the sliding execution electrical appliance 531 and the electric control lock 532. After the execution control module 533 receives the sound insulation layout surface expansion signal emitted by the signal transmission module 11, the execution control module 533 controls the sliding execution electrical appliance 531 to drive the electric control lock 532 to drive the multi-directional folding splint 41 to expand longitudinally.

[0029] In an optional implementation of the present embodiment, the fixed tail frame 1 is fixedly connected to a signal transmission module 11, the three-phase winding 2 is fixedly connected to an acceleration sensor module 21, the signal transmission module 11 is signal-connected to the acceleration sensor module 21, the acceleration sensor module 21 is used to collect the oscillation noise component of the heat sink 3, and the signal transmission module 11 is used to send a sound insulation layout surface switching instruction to the lateral noise reduction and lifting component 5 according to the signal collected by the acceleration sensor module 21.

[0030] In this embodiment, the acceleration sensing module 21 selects an acceleration sensor, which is installed corresponding to the three-phase winding 2, and is used to collect the internal vibration signal of the three-phase winding 2 for noise analysis. The signal transmission module 11 selects a signal transmitter. The signal transmission module 11 is used to obtain the vibration signal collected by the acceleration sensing module 21 and upload it to the external PC system end. The vibration signal is analyzed for noise through the PC end to obtain whether the current vibration noise meets the auxiliary noise reduction requirements. Among them, noise analysis through vibration collection signals is a known technical means, which is not an improvement content of the present invention. Therefore, its technical principle will not be repeated in the technical solution.

[0031] In this embodiment, when the transformer is in operation, the signal transmission module 11 collects the vibration signals obtained by the acceleration sensing module 21 and uploads them to the PC system terminal. The PC system terminal analyzes whether the current vibration noise meets the auxiliary noise reduction requirements based on the vibration signals. When the noise reduction requirements are not met, the multi-directional folding splint 41, the pore noise reduction spacer 42, and the staggered shock absorption spacer 43 are integrally attached to the inner side of the C-shaped buffer bracket 22 to buffer the low-frequency vibration of the three-phase winding 2, and do not affect the normal heat dissipation ventilation surface of the three-phase winding 2 and the heat dissipation fins 3. When the current vibration noise meets the auxiliary noise reduction requirements of the vibration demand, a control signal is sent to the execution control module 533 through the signal transmission module 11, and the execution control module 533 issues the control signal to the sliding execution electrical appliance 531 and the electric control lock 532. At this time, the electric control lock 532 is driven by the sliding execution electrical appliance 531 to climb longitudinally along the longitudinal limiting rod 52, so that the electric control lock 532 drives the multi-directional folding splint 41 to slide towards the top of the longitudinal limiting rod 52. After the electric control lock 532 reaches the apex of the longitudinal limiting rod 52, the signal transmission module 11 sends a locking signal to the electric control lock 532 to control the electric control lock 532 to clamp the longitudinal limiting rod 52 to achieve positioning. At this time, the multi-directional folding splint 41 is in the expanded state (as Figure 5 shown). The pore noise reduction spacer 42 is placed on both sides of the three-phase winding 2 for auxiliary sound insulation until the acceleration sensing module 21 collects that the three-phase winding 2 returns to low-load operation again, and when the signal transmission module 11 analyzes that the vibration impact decreases, the signal transmission module 11 sends a control command to the execution control module 533, and the execution control module 533 issues the control command to the electric control lock 532 and the sliding execution electrical appliance 531 to control the electric control lock 532 to unlock, and drives the electric control lock 532 to slide down along the longitudinal limiting rod 52 through the sliding execution electrical appliance 531 until the multi-directional folding splint 41 is driven by the electric control lock 532 to reset to the inner side of the C-shaped buffer bracket 22, so that the dual-zone switching noise reduction module 4 adapts to the vibration buffer when the noise reduction requirements are not met again.

[0032] In an alternative embodiment of this embodiment, a C-shaped buffer bracket 22 is provided at the bottom of the three-phase winding 2. The C-shaped buffer bracket 22 is fixedly connected to the fixed tail frame 1. The multi-directional folding splint 41, the pore noise reduction spacer 42, and the staggered shock absorption spacer 43 are all slidably connected to the C-shaped buffer bracket 22, and the other end of the multi-directional folding splint 41 is fixedly connected to the inner wall of the C-shaped buffer bracket 22.

[0033] In an alternative embodiment of the present embodiment, the wind direction assisted heat dissipation guiding assembly 6 includes a fin side frame 61, an intermediate connecting pipe 62, and a single-row directional air outlet seat 63. The fin side frame 61 is fixedly connected to the longitudinal limiting support rod 52, the single-row directional air outlet seat 63 is fixedly connected to the fin side frame 61, one end of the intermediate connecting pipe 62 is connected to an external heat dissipation fan, and the other end of the intermediate connecting pipe 62 is fixedly connected to the single-row directional air outlet seat 63.

[0034] In this embodiment, after the multi-directional folding clamping plate 41 is fully extended, the signal transmission module 11 synchronously sends a control signal to the external heat dissipation fan, and the air source is led out to the side direction of the heat dissipation fins 3 through the intermediate connecting pipe 62 and the single-row directional air outlet seat 63, so that the heat generated by the heat dissipation fins 3 is discharged through the channel formed between the two double-zone switching noise reduction modules 4. The rubber fan blade heat dissipation method with a large coverage area can reduce the vibration influence of different frequencies generated by the operation of the heat dissipation fan blades on the three-phase winding 2. At the same time, the single-row directional air outlet seat 63 of the present invention only conducts collaborative heat dissipation when the multi-directional folding clamping plate 41 extends to form a lateral channel, which can reduce the energy consumption required during normal operation.

[0035] The working principle of the present invention is as follows: By setting the double-zone switching noise reduction module 4, the lateral noise reduction enhancement assembly 5, and the wind direction assisted heat dissipation guiding assembly 6 for two-way switching during high-overload noise reduction and low-overload auxiliary shock absorption applications, the adaptability during noise reduction applications is improved. When the transformer is in use, the signal transmission module 11 receives the acquisition signal of the acceleration sensing module 21. When the signal transmission module 11 determines that it is a low-overload application (the vibration noise does not reach the preset value at the PC system end), the multi-directional folding clamping plate 41 is folded and retracted inside the C-shaped buffer bracket 22, so that the misaligned shock absorption spacer 43 is in a misaligned composite state. When the three-phase winding 2 generates low-frequency vibration, the buffer structure composed of the misaligned shock absorption spacers 43 in the composite state serves as auxiliary shock absorption. When high-frequency vibration noise is generated (the vibration noise exceeds the preset value at the PC system end), the multi-directional folding clamping plate 41 can be driven by the directional driver 53 to climb longitudinally along the arrangement path of the longitudinal limiting support rod 52, so that the multi-directional folding clamping plate 41 is in an expanded state and held on the front and back sides of the three-phase winding 2 and the heat dissipation fins 3 after being pulled. In the current state, there is a gap between every two adjacent misaligned shock absorption spacers 43, which does not affect the passage of vibration noise to the pore surface of the pore noise reduction spacer 42, so that the pore noise reduction spacer 42 cooperates with the external noise reduction device to synchronously reduce noise. Until the noise decreases when returning to low-overload operation again, the directional driver 53 drives the multi-directional folding clamping plate 41 to be retracted and reset inside the C-shaped buffer bracket 22, which does not affect the heat dissipation surface of the three-phase winding 2 and the heat dissipation fins 3 under the low-frequency operation state, and at the same time, the double-zone switching noise reduction module 4 conducts collaborative shock absorption on the bottom assembly position of the three-phase winding 2.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
