Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to an amorphous alloy transformer. Background Art

[0002] Amorphous alloy transformers are widely used in transmission networks due to their low no-load loss. If the amorphous alloy core of the amorphous alloy transformer is squeezed, the no-load loss of the amorphous alloy transformer will increase and the noise generated will also increase.

[0003] In order to solve the above problems, in the prior art, the amorphous alloy core is usually suspended on the frame of the amorphous alloy transformer to prevent the amorphous alloy core from being squeezed and deformed. However, when the amorphous alloy core is heavy, the frame is easily deformed by the gravity of the amorphous alloy core, causing the amorphous alloy core to be displaced and come into contact with other components of the amorphous alloy transformer, causing the amorphous alloy core to be squeezed and deformed, and the noise emitted by the amorphous alloy transformer to increase. Summary of the invention

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0030] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0033] When the weight of the amorphous alloy core suspended by the frame of the amorphous alloy transformer is too large, the frame is easily deformed by the gravity of the amorphous alloy core, causing the amorphous alloy core to move and come into contact with other components of the amorphous alloy transformer, causing the amorphous alloy core to be squeezed and deformed. Therefore, preventing the bracket carrying the amorphous alloy core from deforming is the key to solving the above technical problems. Figures 1 to 3 The amorphous alloy transformer provided by the present invention is introduced in detail.

[0034] Figure 1 FIG. 2 shows a schematic diagram of the exploded structure of the amorphous alloy transformer provided in this embodiment. Figure 1 As shown, the amorphous alloy transformer provided in this embodiment includes a shell 1 and a core module 2. A housing cavity is provided in the shell 1, which can accommodate the core module 2. The core module 2 is located in the housing cavity, and the core module 2 includes an amorphous alloy core 21 and a first frame 22. The top of the amorphous alloy core 21 is fixedly connected to the first frame 22, and the first frame 22 is fixedly connected to the inner wall of the shell 1. The amorphous alloy core 21 is spaced apart from the inner wall of the shell 1. It can be understood that the inner wall of the shell 1 includes an inner top wall, an inner side wall and an inner bottom wall. The amorphous alloy core 21 does not contact the inner wall, so that the interaction force between the amorphous alloy core 21 and the inner wall of the shell 1 can be avoided, and the amorphous alloy core 21 is prevented from being squeezed and deformed.

[0035] The amorphous alloy transformer provided in the present embodiment fixes the top end of the amorphous alloy core 21 to the first frame 22, and the first frame 22 is fixedly connected to the inner wall of the shell 1, and the amorphous alloy core 21 is spaced apart from the inner wall of the shell 1, so that the force generated by the gravity of the amorphous alloy core 21 is transmitted to the inner wall of the shell 1 through the first frame 22, so that the inner wall of the shell 1 shares the gravity borne by the first frame 22, and prevents the first frame 22 from being deformed due to excessive gravity, thereby preventing the amorphous alloy core 21 from being displaced and contacting other components of the amorphous alloy transformer, and finally ensuring that the amorphous alloy core 21 will not be squeezed and deformed. At the same time, when the amorphous alloy transformer is running, the noise emitted by the core module 2 will also be transmitted to the inner wall of the shell 1 through the first frame 22. The inner wall of the shell 1 increases the conduction area of ​​the noise, so it can weaken the transmitted sound energy and block the conduction of the noise, thereby reducing the noise emitted by the amorphous alloy transformer during operation.

[0036] Continue as Figure 1 As shown, the shell 1 includes a first shell 11 and a second shell 12, the second shell 12 is arranged on the top of the first shell 11, the first frame 22 is fixedly connected to the inner wall of the first shell 11, the amorphous alloy core 21 and the inner wall of the first shell 11 and the inner wall of the second shell 12 are spaced apart, the first shell 11 and the second shell 12 are buckled together to form an accommodating cavity, so that when the amorphous alloy core 21 is installed in the accommodating cavity, the amorphous alloy core 21 can be hoisted and sent into the accommodating cavity from top to bottom, so as to reduce the assembly difficulty of the amorphous alloy transformer and improve the assembly efficiency of the amorphous alloy transformer.

[0037] Figure 2 The amorphous alloy core 21 has a relatively poor strength. As long as the amorphous alloy core 21 contacts other components of the amorphous alloy transformer and generates a relative force, it may be squeezed and deformed. Figure 1 to Figure 2As shown, the core module 2 also includes a coil 23 and a second frame 24. The coil 23 is wound around the amorphous alloy core 21. One side of the coil 23 is connected to the first frame 22, and the other side is connected to the second frame 24. The first frame 22 corresponds to the second frame 24 and is spaced apart. The amorphous alloy core 21 is disposed between the first frame 22 and the second frame 24 and is spaced apart from the second frame 24. The first frame 22 serves as a protective shell to prevent the top of the amorphous alloy core 21 from contacting other components of the amorphous alloy transformer and generating a relative force. The second frame 24 also serves as a protective shell to prevent the bottom of the amorphous alloy core 21 from contacting other components of the amorphous alloy transformer and generating a relative force. At the same time, the second frame 24 is spaced apart from the amorphous alloy core 21 without contacting it. It also prevents the amorphous alloy core 21 from contacting the second frame 24 and generating a relative force, and the first frame 22 and the second frame 24 are respectively fixedly connected to the coil 23, and the coil 23 is arranged around the amorphous alloy core 21, so that the coil 23 serves as a protective shell to prevent the side surface of the amorphous alloy core 21 from contacting other components of the amorphous alloy transformer and generating a relative force. By setting the first frame 22 and the second frame 24 and connecting one side of the coil 23 to the first frame 22 and the other side to the second frame 24, a protective shell can be obtained to prevent the amorphous alloy core 21 from contacting other components of the amorphous alloy transformer and generating a relative force, thereby preventing the amorphous core 21 from deforming and reducing the noise emitted by the core module 2 when the amorphous alloy transformer is running.

[0038] It is worth noting that the amorphous alloy core 21 is surrounded by three single-frame cores 211, and the contact parts of two adjacent single-frame cores 211 are spliced ​​to form a winding portion 212. The amorphous alloy core 21 has three winding portions 212, and each winding portion 212 is correspondingly wound with a coil 23. Therefore, the coil 23 can serve as a protective shell 112 to prevent the winding portion 212 from directly contacting other components of the amorphous alloy transformer and thus deforming. The single-frame core 211 also includes a core body 2111 and a non-magnetic steel plate shell 2112. The non-magnetic steel plate shell 2112 is wrapped on the outside of the core body 2111. The top of the non-magnetic steel plate shell 2112 is fixed to the first frame 22. The first frame 22 is fixedly connected to the inner wall of the first shell 11, and its bottom end is spaced apart from the second frame 24, so that the amorphous alloy core 21 and the second frame 24 are suspended in the air. The noise of the amorphous alloy core 21 cannot be transmitted through the second frame 24, but is transmitted to the inner wall of the first shell 11 through the first frame 22, thereby transmitting the noise to the inner wall of the first shell 11. The inner wall of the first shell 11 increases the conduction area of ​​the noise, so it can weaken the transmitted sound energy and block the conduction of noise, thereby reducing the noise emitted by the amorphous alloy transformer during operation.

[0039] like Figure 1As shown, the shell 1 also includes a third shell 13, which is arranged at the bottom of the first shell 11, and the second shell 12 and the third shell 13 are respectively buckled with the first shell 11 to form a receiving cavity together. The amorphous alloy core 21 is spaced from the inner wall of the first shell 11, the inner wall of the second shell 12 and the inner wall of the third shell 13. Therefore, when assembling the amorphous alloy core 21, the first shell 11 can be hoisted from top to bottom and the amorphous alloy core 21 can be inserted into the receiving cavity, which further reduces the difficulty of assembling the amorphous alloy transformer.

[0040] Optionally, a first positioning member 131 is provided on the side of the third shell 13 facing the accommodating cavity, and a second positioning member 241 is provided on the second frame 24 to be positioned and matched with the first positioning member 131, so that during the transportation of the amorphous alloy transformer, even if bumps or vibrations occur, the amorphous alloy core 21 can be prevented from shaking, and the shaking of the amorphous alloy core 21 will inevitably increase the force borne by the first frame 22. The above arrangement can also further prevent the first frame 22 from being deformed during the transportation of the amorphous alloy transformer, thereby reducing the difficulty of transporting the amorphous alloy transformer. Specifically, one of the first positioning member 131 and the second positioning member 241 is a positioning pin, and the other is a positioning hole, so that the spatial position of the amorphous alloy core 21 in the horizontal direction can be fixed to prevent it from shaking due to bumps during transportation. Specifically, one of the first positioning member 131 and the second positioning member 241 is a positioning pin, and the other is a positioning hole. When the core module 2 is fixed to the inner wall of the first shell 11, the positioning pin and the positioning hole are positioned and matched, thereby preventing the core module 2 from shaking due to bumps during transportation. It is worth noting that any positioning component that prevents the amorphous alloy transformer from shaking due to bumps during transportation is within the protection scope of this embodiment and will not be described one by one here.

[0041] Continue as Figure 1As shown, a first seal 31 is provided at the connection portion between the first shell 11 and the second shell 12, so that when the amorphous alloy transformer is in operation, when the noise emitted by the amorphous alloy core 21 is transmitted from the first frame 22 to the first shell 11, the noise is prevented from continuing to be transmitted from the first shell 11 to the second shell 12 and leaking out from the second shell 12, so that the noise is only transmitted on the first shell 11, thereby reducing the noise emitted by the amorphous alloy transformer in operation. Similarly, a second seal 32 is provided at the connection portion between the first shell 11 and the third shell 13, so that when the amorphous alloy transformer is in operation, when the noise emitted by the amorphous alloy core 21 is transmitted from the first frame 22 to the first shell 11, the noise is prevented from continuing to be transmitted from the first shell 11 to the third shell 13 and leaking out from the third shell 13, so that the noise is only transmitted on the first shell 11, thereby reducing the noise emitted by the amorphous alloy transformer in operation. Specifically, the first seal 31 and the second seal 32 can be sealing strips or sealing rings. All sealing methods that can achieve a sealed accommodating cavity are within the protection scope of this embodiment. A first accommodating groove for accommodating the first seal 31 is provided at one end where the first shell 11 and the second shell 12 are connected. The first seal 31 is arranged in the first accommodating groove, and can prevent noise from being transmitted to the second shell 12 and leaking out from the second shell 12. A second accommodating groove for accommodating the second seal 32 is provided at one end where the first shell 11 and the third shell 13 are connected. The second seal 32 is arranged in the second accommodating groove, and can prevent noise from being transmitted to the third shell 13 and leaking out from the third shell 13.

[0042] It is worth noting that the second seal 32 in the amorphous alloy transformer provided by the present invention has a certain thickness. By adjusting the thickness of the second seal 32, the distance between the second frame 24 of the core module 2 and the side of the third shell 13 can be adjusted, so that the second frame 24 is in contact with the third shell 13 without being subjected to force. Therefore, during the transportation of the amorphous alloy transformer, the vibration of the core module 2 in the height direction can ensure that the core module 2 will not be displaced in the height direction, thereby preventing the amorphous alloy core 21 from bumping up and down, and reducing the impact of vibration on the performance of the amorphous alloy core 21 during the transportation of the amorphous alloy transformer.

[0043] Figure 3 FIG. 1 shows a cross-sectional view of the first housing 11 provided in the embodiment in the height direction. Although the core module 2 is arranged inside the housing cavity of the housing 1, the noise emitted by the core module 2 can be blocked to a certain extent, the noise emitted by the amorphous alloy transformer is still very high. In order to further reduce the noise emitted by the amorphous alloy core 21, as Figure 1 and Figure 3As shown, the first shell 11 includes an inner shell 111 and an outer shell 112 which are sealed and nested inside and outside. A vacuum chamber 113 is arranged between the inner shell 111 and the outer shell 112. The accommodating chamber is located on the side of the inner shell 111 away from the vacuum chamber 113. The first frame 22 is fixedly connected to the inner wall of the inner shell 111, so as to utilize the characteristic that sound cannot be transmitted in a vacuum, and the noise transmitted to the inner wall of the first shell 11 through the first frame 22 is transmitted to the outer shell 112. The vacuum chamber 113 isolates the noise emitted by the core module 2, and the noise transmitted to the first shell 11 or the second shell 12 is isolated by the seal to prevent the noise from leaking from the first shell 11 or the second shell 12, thereby greatly reducing the noise emitted by the amorphous alloy transformer during operation.

[0044] Optionally, the first shell 11 further includes a sound insulation layer 115, which is disposed in the vacuum cavity 113 and fixedly connected to one of the inner shell 111 or the outer shell 112, thereby further improving the sound insulation effect of the first shell 11. It is worth noting that the sound insulation layer 115 can be any sound insulation material that can absorb noise and reduce the reflection and propagation of sound waves, such as sound-absorbing cotton, rock wool board or polyester fiber board, which will not be described one by one here. The vacuum cavity 113 is not completely filled with the sound insulation layer 115. When the sound insulation layer 115 is fixedly connected to the inner shell 111, the sound insulation layer 115 is arranged at intervals in the outer shell 112, so that when the noise transmitted to the inner wall of the inner shell 111 is transmitted toward the outer shell 112, part of the noise can be first absorbed by the sound insulation layer 115, and the reflection and propagation of sound waves can be reduced, and then the noise is isolated by the vacuum cavity 113. When the sound insulation layer 115 is fixedly connected to the outer shell 112, the sound insulation layer 115 is spaced apart from the inner shell 111, so that the noise transmitted to the inner wall of the inner shell 111 can be first isolated by the vacuum chamber 113 when it is transmitted toward the outer shell 112. When the vacuum degree in the vacuum chamber 113 is insufficient and there is air that can transmit a small amount of noise, the sound insulation layer 115 can also absorb part of the noise and reduce the reflection and propagation of sound waves.

[0045] Continue as Figure 1 and Figure 3As shown, the inner wall of the inner shell 111 is provided with a first connector 114, and the first frame 22 is provided with a second connector 221. The first connector 114 and the second connector 221 are detachably connected, so that the amorphous alloy core 21 can be reliably fixed to the inner wall of the inner shell 111. When the amorphous alloy core 21 is damaged, the amorphous alloy core 21 can be replaced by the detachably connected first connector 114 and the second connector 221, so as to improve the maintainability of the amorphous alloy transformer. Specifically, one of the first connector 114 and the second connector 221 can be a fixing plate with a threaded hole, and the other can be a fixing plate with a connecting through hole, and the two fixing plates are bolted together by bolts. Of course, in other embodiments, other first connectors 114 and second connectors 221 that can be detachably connected are also within the protection scope of this embodiment, and will not be described one by one here.

[0046] Continue as Figure 1 and Figure 2 As shown, a first through hole connected to the vacuum chamber 113 is provided on the shell 112, and a vacuum valve 41 is fixed at the first through hole, so that when the vacuum chamber 113 leaks and enters the air, the vacuum valve 41 can be used to evacuate the vacuum chamber 113 again, so that the vacuum chamber 113 can be better isolated from the conduction of noise, so as to improve the sound insulation effect of the vacuum chamber 113.

[0047] Furthermore, a second through hole connected to the vacuum chamber 113 is provided on the shell 112, and an air pressure detector 42 is fixed at the second through hole. The detection end of the air pressure detector 42 extends into the vacuum chamber 113 and can detect the pressure in the vacuum chamber 113. The display end of the air pressure detector 42 is arranged on the side of the shell 112 away from the vacuum chamber 113, and can display the atmospheric pressure in the vacuum chamber 113 for viewing by the staff. When the staff observes the display end of the air pressure detector 42 and finds that the vacuum chamber 113 is leaking, the vacuum chamber 113 can be re-evacuated in time through the vacuum valve 41 to maintain the sound insulation effect of the vacuum chamber 113.

[0048] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
