Fusible and detachable composite sound insulation cover and transformer device

Abstract

The present application relates to the technical field of sound insulation apparatuses, and relates to a fusible and detachable composite sound insulation cover and a transformer device having same. The fusible and detachable composite sound insulation cover comprises: a fixed module, configured to be fixedly connected to an external device; a movable module, welded and connected to the fixed module by means of a fusible wire; and sound insulation board bodies, fixedly installed on the movable module, wherein a plurality of sound insulation board bodies surround and define a closed accommodation space used for accommodating the external device. The composite sound insulation cover is used to enclose the transformer device, and the transformer device is installed in the accommodation space, so that noise generated by the transformer device during operation is blocked. When a fire occurs in the substation, the fusible wire melts in a high-temperature environment, such that the movable module automatically separates from the fixed module and detaches, causing the sound insulation board bodies to automatically fall off from the transformer device, thereby eliminating the obstruction of the sound insulation cover during firefighting. In this way, firefighting equipment can directly extinguish the fire on the transformer device, eliminating potential safety hazards posed by the sound insulation cover.

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202310974889.2 and application date of August 3, 2023, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby incorporated into this application by introduction. Technical Field

[0003] The present application relates to the technical field of sound insulation devices, and in particular to a fusible and detachable composite sound insulation cover and a power transformation device. Background Art

[0004] The construction of the energy and power Internet of Things with ultra-high voltage power grid as the backbone is progressing steadily, and the scale of the substation equipment industry is expanding rapidly. While the project is under construction, environmental problems represented by audible noise from substation equipment are bringing significant environmental pressure to the power grid.

[0005] Currently, noise control in substations (converter stations) primarily relies on noise barriers and enclosures. However, noise barriers have a narrow sound shadow area, and their noise reduction effect decreases as the distance from the receiving point increases. Therefore, they cannot fully meet the low-noise requirements surrounding substations (converter stations). While enclosures can completely enclose substation equipment, they make extinguishing the fire difficult due to the enclosure's obstruction, posing a significant fire safety hazard.

[0006] Summary of the Invention

[0007] Therefore, the technical problem to be solved by the embodiments of the present application is to overcome the defect that the substation equipment enclosed by the sound insulation enclosure will bring about a high fire safety hazard, thereby providing a fusible and detachable composite sound insulation enclosure and substation equipment having the same.

[0008] The present application provides a fusible and detachable composite sound insulation enclosure, comprising:

[0009] A fixed module, suitable for fixed connection with external equipment;

[0010] The mobile module is connected to the fixed module by welding with a fusible connection;

[0011] The sound insulation board body is fixedly mounted on the mobile module. A plurality of sound insulation board bodies form a closed accommodation space for accommodating external equipment.

[0012] In some embodiments, the surface of the mobile module connected to the fixed module is a connecting slope, and the connecting slope is set at an angle to the horizontal plane.

[0013] In some embodiments, the connecting slope is provided on a side of the movable module facing away from the sound insulation board body.

[0014] In some embodiments, the moving module is composed of a first moving block and a second moving block that are separately provided, and the first moving block and the second moving block are arranged in a vertical direction.

[0015] In some embodiments, the first moving block and the second moving block are further connected by welding via an auxiliary fusible link.

[0016] In some embodiments, the melting point of the disconnect wire and / or the auxiliary fusible link is 100°C-200°C.

[0017] In some embodiments, the first moving block and the second moving block are fixedly connected to different sound insulation board bodies respectively.

[0018] In some embodiments, a connecting bolt is further included, which passes through the sound insulation board body and is threadedly engaged with the movable module to fixedly connect the sound insulation board body and the movable module.

[0019] The embodiment of the present application further provides a power transformation device, comprising the above-mentioned fusible and detachable composite sound insulation cover, wherein the accommodation space enclosed by the multiple sound insulation board bodies 2 of the fusible and detachable composite sound insulation cover is used for installing the power transformation device body.

[0020] In some embodiments, multiple components within the power transformation equipment body are respectively installed in different accommodation spaces.

[0021] The fusible and detachable composite sound insulation enclosure provided in an embodiment of the present application includes: a fixed module adapted to be fixedly connected to an external device; a movable module welded to the fixed module via a fusible connection; and a sound insulation panel body fixedly mounted on the movable module. The plurality of sound insulation panel bodies enclose a closed accommodation space for accommodating the external device.

[0022] A fusible composite soundproof enclosure is used to enclose the substation's substation equipment, which is then installed within the enclosure to block the noise generated by the substation's operation. When a fire occurs within the substation, the resulting high temperatures are transferred to the fusible wires between the fixed and mobile modules. Due to the fusible wires' low melting point, they melt in the high-temperature environment, causing the mobile modules to automatically separate and fall away from the fixed modules. This, in turn, causes the soundproof panels to automatically fall away from the substation equipment, eliminating the obstruction of the soundproof enclosure during firefighting operations. This allows firefighting equipment to directly extinguish the substation equipment, eliminating the safety hazards associated with the soundproof enclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0029] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1

[0031] As shown in FIG. 1 and FIG. 2 , a fusible and detachable composite sound insulation enclosure provided in this embodiment includes: a fixed module 1 , a movable module and a sound insulation board body 2 .

[0032] The fixed module 1 is adapted for fixed connection to external equipment. The mobile module is welded to the fixed module 1 via a fusible link 8. The sound insulation panel body 2 is fixedly mounted on the mobile module. Multiple sound insulation panel bodies 2 form a closed space for accommodating external equipment. If a fire occurs near the external equipment, the high temperatures generated by the fire will melt the fusible link 8, disconnecting the mobile module from the fixed module 1. This allows the sound insulation panel body 2 to be quickly removed from the external equipment, exposing the equipment to the outside world and facilitating direct firefighting and cooling of the equipment using firefighting equipment.

[0033] Figure 1 shows a schematic diagram of the connection between the movable module and the fixed module 1 on an external device. To facilitate direct viewing of the movable and fixed modules 1, the sound insulation panel body 2 is hidden in Figure 1. The surface of the movable module that connects to the fixed module 1 is a connecting slope, angled with the horizontal plane. The connecting slope is located on the side of the movable module facing away from the sound insulation panel body 2. In this embodiment, the movable module comprises a first movable block 3 and a second movable block 4, which are arranged vertically. Both the first movable block 3 and the second movable block 4 are rectangular trapezoidal blocks, with the top edge of the first movable block 3 and the top edge of the second movable block 4 facing each other. The right-angled sides of the first movable block 3 and the right-angled sides of the second movable block 4 are aligned. Furthermore, the first movable block 3 is positioned above the second movable block 4, so that the connecting slope of the first movable block 3 with the fixed module 1 is tilted downward, while the connecting slope of the second movable block 4 with the fixed module 1 is tilted upward.

[0034] In the fusible composite sound insulation enclosure provided in the present application, the connection surface between the mobile module and the fixed module is a sloped surface, which is arranged at an angle to the horizontal plane. This slope creates an incline between the mobile module and the fixed module, preventing the fixed module from forming a stable support structure between the two modules. This allows the mobile module to automatically fall off under its own weight after the fusible connection melts.

[0035] To enhance the stability of the connection between the first and second movable blocks 3, 4 and prevent them from falling off during use, the first and second movable blocks 3, 4 are welded together via an auxiliary fusible link 9. To ensure quick removal of the sound insulation board body 2, the first and second movable blocks 3, 4 are fixedly connected to different sound insulation board bodies 2.

[0036] The fusible and removable composite sound insulation enclosure provided in the present application comprises a movable module comprising a first movable block and a second movable block, each of which is arranged vertically. By arranging the movable module in a split configuration, the fusible link melts simultaneously at multiple nodes when exposed to high temperatures, increasing the melting speed and enabling rapid removal of the sound insulation panel in a fire environment.

[0037] As shown in Figure 2, to facilitate installation of the sound insulation panel body 2 on the mobile module, the present embodiment of the present invention includes connecting bolts 5 that penetrate the panel body 2 and threadably engage with the mobile module, thereby securely connecting the panel body 2 to the mobile module. To enhance the stability of the connection between the panel body 2 and the mobile module, angle steel 7 is provided on the outside of the panel body 2. The connecting bolts 5 penetrate the angle steel 7 and the panel body 2, then threadably engage with the mobile module. The angle steel 7 and the mobile module securely clamp the panel body 2. The angle steel 7 extends along the edge of the panel body 2, completely covering the edge of the panel body 2 and enhancing its stability.

[0038] In the embodiments of the present application, the fixed module 1 and the movable module can both be made of brass or steel. The fusible link 8 and / or auxiliary fusible link 9 are low-melting-point alloys with a melting point of 100°C-200°C. The fusible and removable composite soundproof enclosure includes the fixed module 1, a first movable block 3, a second movable block 4, and fusible links 8. The fusible links 8 include a first fusible link between the fixed module 1 and the first movable block 3, and a second fusible link between the fixed module 1 and the second movable block 4. To securely connect the fixed module 1 to the first movable block 3, a low-melting-point alloy is melted and connected by welding to form the first fusible link. To securely connect the fixed module 1 to the second movable block 4, a low-melting-point alloy is melted and connected by welding to form the second fusible link. Specifically, a sloped surface is designed between the fixed module 1 and the movable module to facilitate the downward sliding of the movable module in the event of an equipment fire. To securely connect the fixed module 1 to the T-shaped keel 6 on the external equipment, one side of the fixed module 1 is fixedly connected to the T-shaped keel 6 by bolts. In order to connect the movable module to the sound insulation board body 2, one side of the movable module is fixed to the angle steel 7, and the other side of the angle steel 7 is fixedly connected to the sound insulation board body 2 and the movable module by bolts.

[0039] As the low melting point alloy for the fuse link 8 and the auxiliary fuse link 9, a bismuth-indium alloy (BiIn) with a solidus of 105°C and a liquidus of 109°C may be used; or a bismuth-lead-tin alloy (BiPbSn) with a solidus of 115°C and a liquidus of 126°C may be used; or a tin-indium alloy (SnIn) with a solidus of 118°C and a liquidus of 145°C may be used; or a tin-bismuth alloy (SnBi) with a solidus of 138°C and a liquidus of 170°C may be used.

[0040] A fusible composite soundproof enclosure encloses the substation's transformer equipment, which is mounted within a storage space to block noise generated by the equipment during operation. When a fire occurs within the substation, the resulting high temperatures are transferred to the fusible link 8 between the fixed module 1 and the mobile module. Due to its low melting point, the fusible link 8 melts in the high-temperature environment, causing the mobile module to automatically separate from the fixed module 1 and fall off. This, in turn, causes the soundproof panel 2 to automatically fall off the substation's body, eliminating the soundproof enclosure's obstruction during firefighting operations. This allows firefighting equipment to directly extinguish the substation fire, eliminating the potential safety hazards associated with the soundproof enclosure.

[0041] Example 2

[0042] This embodiment provides a power transformer, including the fusible composite sound insulation enclosure described in Example 1. The fusible composite sound insulation enclosure comprises a plurality of sound insulation panel bodies 2, which define a receiving space for mounting the power transformer. The power transformer is mounted within the receiving space formed by the plurality of sound insulation panel bodies 2. A fixing module is bolted to the T-shaped keel of the power transformer.

[0043] As an alternative embodiment, the multiple components in the power transformation equipment body are respectively installed in different accommodation spaces.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the embodiments of this application.
