Description

Technical Field

[0001] This application relates to the field of power supply system technology, and in particular to a power supply device with high voltage protection. Background Technology

[0002] Power Feeding Equipment (PFE) is a key component of underwater communication systems, providing a stable and reliable power supply to underwater equipment within the system.

[0003] The PFE can safely convert low voltage to the high voltage required by underwater equipment through converter (CV) modules. Multiple CV modules are connected in series in the PFE, which can generate a voltage of up to 18KV to power the underwater equipment.

[0004] PFEs typically support hot-swapping of CV modules to prevent CV module replacement and maintenance from affecting the power supply to underwater equipment. However, during CV module hot-swapping, the high-voltage connectors at the connection point between the CV module and the PFE cabinet are exposed to the air, increasing the risk of electric shock for maintenance personnel when connecting the CV module and hindering the implementation of PFE maintenance work. Utility Model Content

[0005] This application provides a power supply device with high-voltage protection to address the high risk of electric shock when maintaining power supply equipment for underwater communication systems.

[0006] This application provides a power supply device with high-voltage protection, including a cabinet and at least one converter module. The cabinet is formed by a first side panel, a second side panel, and a back panel. At least one slide rail is provided on each of the first and second side panels, allowing the converter module to be installed into the cabinet via the slide rails. The cabinet includes at least one connector and at least one high-voltage protection plate. Each connector is disposed on the back panel, and when the converter module is installed in the cabinet, the converter module is connected to at least one connector. Each high-voltage protection plate is rotatably disposed between the first and second side panels. When the converter module is not installed, the high-voltage protection plate is parallel to the back panel. The height of the high-voltage protection plate is less than or equal to the thickness of the converter module, and the vertical distance between the high-voltage protection plate and the back panel is greater than the thickness of the converter module. When the converter module is installed into the cabinet via the slide rails, the high-voltage protection plate rotates in a first direction, which is the direction closer to the back panel.

[0007] The power supply equipment provided in this application embodiment, by setting a protective structure in the cabinet, can achieve the purpose of high voltage isolation while only making structural changes to the external structure of the cabinet and converter module, avoiding the exposure of high voltage connectors in the cabinet, reducing the risk of electric shock to maintenance personnel during maintenance, improving safety, and at the same time, the implementation cost is low and the cost of modifying existing equipment is low.

[0008] In one feasible implementation, the converter module is provided with a sliding block protruding from the side of the converter module facing the back panel. When the converter module is installed in the rack, the sliding block pushes the high-voltage protection plate to rotate closer to the back panel. This allows the converter module to transfer thrust to the high-voltage protection plate during installation, enabling the high-voltage protection plate to rotate to an angle that no longer obstructs the connectors during the installation process.

[0009] In one feasible implementation, the end of the sliding block furthest from the converter module has an arc-shaped structure. This reduces friction between the sliding block and the high-voltage protection plate during installation, improving the durability and safety of the structure.

[0010] In one feasible embodiment, the high-voltage protection plate is a rectangular plate structure, hinged to a first side panel and a second side panel respectively. The high-voltage protection plate is coaxially arranged at a first hinge position on the first side panel and a second hinge position on the second side panel. In this way, the high-voltage protection plate can block connectors within a certain area, and the coaxial hinge positions determine the rotation axis of the high-voltage protection plate when it rotates under force, thus enabling the high-voltage protection plate to switch between blocking and releasing the connectors.

[0011] In one feasible embodiment, the cabinet further includes a limiting component, which includes two limiting springs disposed opposite to each other on a first side panel and a second side panel. The two limiting springs are disposed along a first direction, with one end of the limiting spring away from the back panel connected to the first or second side panel by bolts, and a first gap provided between the end of the limiting spring near the back panel and the first or second side panel. The distance between the ends of the two limiting springs near the back panel is less than the width of the high-voltage protection plate. After the converter module is pulled out of the cabinet, the ends of the two limiting springs near the back panel engage with the side of the high-voltage protection plate away from the first or second hinge position. In this way, the high-voltage protection plate can be fixed by the engagement relationship between the limiting springs and the high-voltage protection plate, preventing the high-voltage protection plate from being pushed by other forces other than the installed converter module, and improving the shielding efficiency of the high-voltage protection plate for the plug-in components.

[0012] In one feasible embodiment, the converter module has at least one sliding strip on the side facing the first side panel and the side facing the second side panel respectively. The sliding strip protrudes from the surface of the converter module, and the sum of the widths of the converter module and the sliding strip is less than the distance between the first and second side panels. The sum of the widths of the converter module and the sliding strip is greater than the width of the high-voltage protection plate. When the converter module is installed in the cabinet, the sliding strip abuts against the limiting springs, such that the distance between the ends of the two limiting springs closest to the back panel is greater than the width of the high-voltage protection plate. In this way, the converter module can use the sliding strip to release the limiting springs from the high-voltage protection plate during installation, allowing the high-voltage protection plate to rotate under the thrust of the converter module and release its obstruction of the connector.

[0013] In one feasible implementation, one end of the two limiting springs near the back panel has a snap-fit ​​structure, and the high-voltage protection plate has a snap-fit ​​groove. After the converter module is pulled out of the cabinet, the two limiting springs snap into the high-voltage protection plate based on the cooperation between the snap-fit ​​structure and the snap-fit ​​groove. In this way, the snap-fit ​​between the high-voltage protection plate and the limiting springs can be more secure, preventing the high-voltage protection plate from being pushed and rotated by other thrusts outside the installed converter module.

[0014] In one feasible embodiment, the first hinge position and the second hinge position are respectively disposed in the second direction of the corresponding limiting spring, the second direction including a direction perpendicular to the first direction and extending along the first side panel or the second side panel. This allows the hinge position to be located in the second direction of the limiting spring, facilitating the high-voltage protection plate to return to the state of blocking the connector when the converter module is pulled out.

[0015] In one feasible implementation, the thickness of the slide rail is less than the first gap. The slide rail is positioned between the first hinge position and the limiting spring on the first side panel, or between the second hinge position and the limiting spring on the second side panel. This ensures that the slide rail does not obstruct the rotation of the high-voltage protection plate, reducing friction between the various structures within the cabinet.

[0016] In one feasible implementation, a power module is also included, electrically connected to the connector. After the converter module is installed in the rack, the power module is electrically connected to the converter module via the connector. In this way, the power module can provide the converter module with the current it uses for conversion, enabling the converter module to output other forms of current. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings.

[0029] In the description of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0030] It should also be understood that, in this application, unless otherwise expressly specified and limited, the term "connection" can be an electrical connection, a communication connection, or a physical connection; and "connection" can be a direct connection or an indirect connection through an intermediate medium.

[0031] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0032] The following is an explanation of the technical terms used in this application.

[0033] Power Feeding Equipment (PFE) is a key component of underwater communication systems, providing a stable and reliable power supply to underwater equipment within the system.

[0034] A converter (CV) module, also known as a power converter, is used to convert one form of voltage or current into another. In the embodiments of this application, the CV module can safely convert low voltage to the high voltage required by underwater equipment. Multiple CV modules can be connected in series in the PFE to generate a voltage of up to 18KV to power underwater equipment in the underwater communication system.

[0035] Figure 1 This is a schematic diagram of a remote power supply device.

[0036] like Figure 1 As shown, the remote power supply equipment 1 may include a cabinet 2, a converter module 3 and a power module (not shown in the figure). The cabinet 2 may be a cabinet structure installed on the floor of the equipment room, which can be used to accommodate at least one converter module 3. The cabinet 2 is equipped with a power module connected to the converter module 3. The converter module 3 can convert the output of the power module into a high voltage output to power the underwater communication system.

[0037] A cabinet 2 can typically house multiple interconnected converter modules 3, and usually includes a backup converter module 3, so that when the remote power supply equipment 1 is maintaining the converter module 3, its output voltage is maintained, thereby improving the power supply stability of the remote power supply equipment 1.

[0038] However, when maintaining converter module 3, it is necessary to hot-swap converter module 3 to ensure uninterrupted power supply to remote power supply equipment 1. However, hot-swapping converter module 3 exposes the high-voltage connectors at the connection points of converter module 3 in cabinet 2 to the air, increasing the maintenance risk for maintenance personnel and making it difficult for them to maintain remote power supply equipment 1.

[0039] Therefore, this application provides a power supply device with high-voltage protection, which isolates maintenance personnel from the high-voltage connectors corresponding to the converter module during the installation and disassembly of the converter module, thereby reducing the risk of electric shock to maintenance personnel and improving the maintenance safety of the power supply device.

[0040] Figure 2 This is a schematic diagram of a power supply device with high-voltage protection provided in an embodiment of this application.

[0041] like Figure 2 As shown in the embodiment of this application, a power supply device with high voltage protection is provided. The power supply device includes a cabinet 10 and at least one converter module 20. The cabinet 10 is formed by a first side panel 11, a second side panel 12 and a back panel 13. The converter module 20 can be disposed in the cavity formed by the first side panel 11, the second side panel 12 and the back panel 13, and realizes the voltage conversion function by connecting to a power source.

[0042] It should be understood that the cabinet 10 provided in this application embodiment is usually installed on the ground. The first side panel 11, the second side panel 12 and the back panel 13 are all installed perpendicular to the ground. Correspondingly, the end of the cabinet 10 closest to the ground can be the lower end of the cabinet 10, and the end of the cabinet 10 furthest from the ground can be the upper end of the cabinet.

[0043] Furthermore, each converter module 20 has the same structure to ensure that each converter module 20 has the same function. Based on this, the space occupied by each converter module 20 in the rack 10, and the installation method of the converter module 20 and the rack 10, are the same to facilitate the installation and maintenance of the converter module 20.

[0044] In some embodiments of this application, at least one slide rail 101 may be arrayed on the first side panel 11 and the second side panel 12 respectively, and the converter module 20 can be installed into the rack 10 through the slide rail 101. The number of slide rails 101 on the first side panel 11 is the same as the number of slide rails 101 on the second side panel 12, and the slide rails 101 on the first side panel 11 and the slide rails 101 on the second side panel 12 are arranged opposite to each other. The oppositely arranged slide rails 101 constitute a group of slide rails 101. The number of groups of slide rails 101 in the rack 10 determines the upper limit of the converter module 20 that can be installed in the rack 10. For example, if the rack 10 has 5 groups of slide rails 101, then a maximum of 5 converter modules 20 can be installed in the rack 10. In some embodiments of this application, the rack 10 has 7 groups of slide rails 14, so that a maximum of 7 converter modules 20 can be installed in the power supply equipment, realizing a power supply state of 6 working and 1 backup.

[0045] It should be noted that the converter module 20 has an input terminal and an output terminal. The converter module 20 can receive low-voltage current through the input terminal, convert it into high-voltage current, and output it through the output terminal. The output terminals of the converter modules 20 installed in the same cabinet 10 are connected in series, so that the output voltage meets the requirements of the underwater communication system. For example, the cabinet 10 also includes at least one connector 14, and each connector 14 that can be connected to the output terminal of the converter module 20 is connected in series. When the converter modules 20 are installed in the cabinet 10, the output terminals of different converter modules 20 can be connected together in series through the connectors 14.

[0046] In some embodiments, connector 14 includes a low-voltage connector and a high-voltage connector. The low-voltage connector can be connected to the input terminal of converter module 20, and the high-voltage connector can be connected to the output terminal of converter module 20. High-voltage connectors in the same cabinet 10 can be connected in series, so that the output voltages of multiple converter modules 20 are superimposed to a corresponding value to power the underwater communication system. One converter module 20 can be connected to at least one low-voltage connector and at least one high-voltage connector.

[0047] It should be understood that the power supply equipment may also include a power module, which is electrically connected to connector 14. After the converter module 20 is installed in the rack 10, the power module is electrically connected to the input terminal of the converter module 20 through connector 14 to provide low-voltage current for conversion to the converter module 20. It should be understood that connector 14 is a low-voltage connector, and the output of the power module can be input to the installed converter module 20 through the low-voltage connector.

[0048] In this embodiment, the connector 14 is disposed on the back panel 13. When the converter module 20 is installed in the cabinet 10, the output terminal of the converter module 20 can be connected to a connector 14 to output a high voltage output current.

[0049] However, when a converter module 20 is in operation in the cabinet 10, due to the series connection between the connectors 14, even connectors 14 not connected to the converter module 20 will still carry the output voltage and high-voltage current of the in-operation converter module 20. In this situation, removing the in-operation converter module 20 from the cabinet 10 or installing a new converter module 20 into the cabinet 10 poses a risk of electric shock and is detrimental to the maintenance of the converter module 20.

[0050] Therefore, in this embodiment, at least one high-voltage protection plate 15 is provided in the rack 10 in the direction away from the back panel 13, wherein the number of high-voltage protection plates 15 is the same as the number of converter modules 20 that can be installed in the rack 10. For example, if a maximum of 7 converter modules 20 can be installed in the rack 10, a total of 7 high-voltage protection plates 15 are provided in the rack 10.

[0051] Furthermore, each high-voltage protection plate 15 is rotatably disposed between the first side panel 11 and the second side panel 12. When the converter module 20 is not installed, the high-voltage protection plate 15 is arranged parallel to the back panel 13. In this embodiment, the side of the high-voltage protection plate 15 closest to the upper end of the cabinet 10 is hinged to the first side panel 11 and the second side panel 12. When the converter module 20 is not installed, the high-voltage protection plate 15 is subject to gravity and is parallel to the back panel 13 to block the connector 14 disposed on the back panel 13. During the installation of the converter module 20 into the cabinet 10, the high-voltage protection plate 15 can rotate along the side closest to the upper end of the cabinet 10 under the influence of the pushing force of the converter module 20, thereby releasing the high-voltage protection plate 15 from blocking the connector 14.

[0052] Figure 3 This is a structural schematic diagram of a high-voltage protection plate provided in an embodiment of this application.

[0053] In some embodiments, such as Figure 3As shown, the high-voltage protection plate 15 can be a rectangular plate structure. Two hinges 152 are provided on one side of the high-voltage protection plate 15 near the upper end of the cabinet 10. The high-voltage protection plate 15 is hinged to the first side panel 11 and the second side panel 12 respectively via the hinges 152. The high-voltage protection plate 15 is coaxially positioned at the first hinge position on the first side panel 11 and the second hinge position on the second side panel 12. In this way, the high-voltage protection plate 15 can rotate along the axis corresponding to the first and second hinge positions when installing the converter module 20. During installation, the converter module 20 can be rotated to an angle that does not obstruct the connector 14, allowing the converter module 20 to connect smoothly to the connector 14.

[0054] For example, the height of the high-voltage protection plate 15 is less than or equal to the thickness of the converter module 20, so that the high-voltage protection plate 15 corresponds one-to-one with the position in the rack 10 used to install the converter module 20, and different high-voltage protection plates 15 will not occupy the installation space of other converter modules 20. It should be noted that the height of the high-voltage protection plate 15 refers to the distance between the side of the high-voltage protection plate 15 closest to the lower end of the rack 10 and the side of the high-voltage protection plate 15 closest to the upper end of the rack 10, and the thickness of the converter module 20 refers to the distance between the side of the converter module 20 closest to the lower end of the rack 10 and the side of the converter module 20 closest to the upper end of the rack 10 when the converter module 20 is installed in the rack 10.

[0055] When the converter module 20 is installed into the cabinet 10 via the slide rail 101, the high-voltage protection plate 15 can rotate in a first direction as the converter module 20 is pushed forward. The first direction is towards the back panel 13. In order to enable the high-voltage protection plate 15 to rotate smoothly in the first direction, the vertical distance between the high-voltage protection plate 15 and the back panel 13 is greater than the thickness of the converter module 20, so that the high-voltage protection plate 15 will not come into contact with the back panel 13 or the connector 14 provided on the back panel 13 when rotating in the first direction.

[0056] It should be understood that by using the high-voltage protection plate 15, which is hinged to the first side panel 11 and the second side panel 12 on the side near the upper end of the cabinet 10, it can not only shield the connector 14, but also restore the shielding state of the connector 14 by its own gravity when the converter module 20 is pulled out, thereby reducing the exposure time of the live connector 14 and thus reducing the risk of electric shock to maintenance personnel during maintenance.

[0057] Figure 4 This is a schematic diagram of a converter module provided in an embodiment of this application.

[0058] In this embodiment, corresponding components can be provided on the front and rear ends of the converter module 20 to facilitate maintenance personnel in installing it into the rack 10. The rear end of the converter module 20 refers to the end that contacts the connector 14 when the converter module 20 is installed in the rack 10, while the front end of the converter module 20 refers to the end opposite to the rear end. Figure 4 As shown, the front end of the converter module 20 may be provided with a front panel 23, and the front panel 23 is provided with an installation handle 24, so that maintenance personnel can use the installation handle 24 to apply pushing or pulling force to the converter module 20 during the installation or removal of the converter module 20, so as to push the converter module 20 into the cabinet 10 or pull the converter module 20 out of the cabinet 10.

[0059] For example, in this embodiment, the thickness of the converter module 20 refers to the height of the front panel 23 of the converter module 20. The height of the front panel 23 refers to the distance between the side of the front panel 23 closest to the lower end of the cabinet 10 and the side of the front panel 23 closest to the upper end of the cabinet 10 when the converter module 20 is installed in the cabinet 10. Therefore, the height of the high-voltage protection plate 15 can be set to be less than or equal to the height of the front panel 23.

[0060] In this embodiment, the height of the front panel 23 is slightly greater than the thickness of the main body of the converter module 20. The main body of the converter module 20 refers to the portion located inside the cabinet 10 when the converter module 20 is placed within the cabinet 10. After the converter module 20 is installed in the cabinet 10, a certain gap needs to be provided between the main bodies of adjacent converter modules 20 to accommodate the high-voltage protection plate 15 rotated to the side of the corresponding converter module 20 closest to the top of the cabinet 10. Setting the height of the front panel 23 slightly greater than the thickness of the main body of the converter module 20 allows it to cooperate with the front panel 23 after the adjacent converter modules 20 are installed, effectively blocking the gaps between adjacent converter modules 20. This reduces the gaps on the side of the cabinet 10 furthest from the back panel 13 after the converter modules 20 are installed, thus reducing the risk of leakage and electric shock.

[0061] Similarly, setting the height of the high-voltage protection plate 15 to be less than or equal to the height of the front panel 23 can reduce the gap between adjacent high-voltage protection plates 15 and prevent friction between the high-voltage protection plate 15 and adjacent high-voltage protection plates 15 during rotation.

[0062] like Figure 4As shown in some embodiments of this application, the converter module 20 is provided with a sliding block 21. The sliding block 21 protrudes from the converter module 20 on the side facing the back panel 13, that is, the sliding block 21 is located at the rear end of the converter module 20. The sliding block 21 is located on the side of the converter module 20 near the upper end of the cabinet 10. When the converter module 20 is installed in the cabinet 10, the protruding sliding block 21 can push the high-voltage protection plate 15 to rotate towards the back panel 13.

[0063] Furthermore, the end of the sliding block 21 furthest from the converter module 20 is provided with an arc-shaped structure 210, which faces the upper end of the rack 10 when the converter module 20 is installed in the rack 10. When the converter module 20 is installed in the rack 10, the arc-shaped structure 210 can reduce the friction between the sliding block 21 and the high-voltage protection plate 15, and prevent the high-voltage protection plate 15 from being damaged when the sliding block 21 pushes it.

[0064] It should be understood that the purpose of providing a high-voltage protection plate 15 in the cabinet 10 is to prevent the corresponding connector 14 from being exposed to the air after the converter module 20 is pulled out. In some embodiments of this application, when the converter module 20 is pulled out of the cabinet 10, the high-voltage protection plate 15 is affected by gravity and returns to a state parallel to the back panel 13. At this time, the cabinet 10 can fix the state of the high-voltage protection plate 15, preventing the high-voltage protection plate 15 from being exposed by other external forces. In this way, the high-voltage protection plate 15 cannot be opened by any action other than installing the converter module 20, thereby improving the high-voltage protection effect of the high-voltage protection plate 15.

[0065] Figure 5 This is a schematic diagram of a cabinet provided in an embodiment of this application.

[0066] like Figure 5 As shown in (a), in some embodiments, the cabinet 10 may further include a limiting component 16 to maintain the state of the high-voltage protection plate 15 after it has been reset, preventing it from being opened by any action other than the installation of the converter module 20. It should be understood that the limiting component 16 in this embodiment is for one high-voltage protection plate 15. When the cabinet 10 is provided with multiple high-voltage protection plates 15, the cabinet 10 also includes the same number of limiting components 16.

[0067] In this embodiment, the limiting component 16 includes two limiting spring pieces 161 disposed opposite to each other on the first side panel 11 and the second side panel 12. The two limiting spring pieces 161 are disposed along a first direction, that is, the two limiting spring pieces 161 are disposed on the first side panel 11 or the second side panel 12 in a direction close to the back panel 13. Specifically, one end of one limiting spring piece 161, away from the back panel 13, is bolted to the first side panel 11, and the end closer to the back panel 13 has a first gap with the first side panel 11. The other limiting spring piece 161, away from the back panel 13, is bolted to the second side panel 12, and the end closer to the back panel 13 has a first gap with the second side panel 12.

[0068] Specifically, the limiting spring 161 can be a rectangular strip structure, and the limiting spring 161 is provided with a bending structure, so that the two ends of the limiting spring 161 are not on the same horizontal plane, so that when one end of the limiting spring 161 is fixed on the first side panel 11 or the second side panel 12, the other end of the limiting spring 161 has a first gap with the first side panel 11 or the second side panel 12.

[0069] It should be noted that each high-voltage protection plate 15 corresponds to at least one limiting component 16. The first hinge position or the second hinge position is located in a second direction near the end of the limiting spring 161 of the corresponding limiting component 16 close to the back panel 13. The second direction includes a direction perpendicular to the first direction and extending along the first side panel 11 or the second side panel 12. For example, the second direction may be a direction from the lower end of the cabinet 10 to the upper end of the cabinet 10. Therefore, the limiting spring 161 is actually located below the corresponding first hinge position or second hinge position.

[0070] Furthermore, the distance between the ends of the two limiting springs 161 closest to the back panel 13 is less than the width of the high voltage protection plate 15. After the converter module 20 is pulled out of the cabinet 10, the ends of the two limiting springs 161 closest to the back panel 13 engage with the side of the high voltage protection plate 15 away from the upper end of the cabinet 10.

[0071] In the embodiments of this application, such as Figure 5 As shown in (b), one end of the two limiting springs 161 near the back panel 13 has a snap-fit ​​structure 162, and the high-voltage protection plate 15 has a snap-fit ​​groove 151. After the converter module 20 is pulled out of the cabinet 10, the two limiting springs 161 snap into the high-voltage protection plate 15 based on the cooperation between the snap-fit ​​structure 162 and the snap-fit ​​groove 151. If any action other than inserting the converter module 20 is applied at this time, such as directly pushing the high-voltage protection plate 15, the high-voltage protection plate 15 cannot be pushed because of the snap-fit ​​state between the limiting component 16 and the high-voltage protection plate 15.

[0072] It should be noted that, Figure 5 The structure shown in (b) is only for illustrative purposes, illustrating the snap-fit ​​structure 162 on the limiting spring 161 and the snap-fit ​​groove 151 on the high-voltage protection plate 15. In actual applications, without inserting or removing the converter module 20, the positional relationship between the high-voltage protection plate 15 and the limiting spring 161 can be as follows: Figure 5 The positional relationships shown in (b) are different.

[0073] It should be understood that the slide rails 101 provided on the first side panel 11 and the second side panel 12 have a first thickness to support the converter module 20 during installation and removal. Simultaneously, the sum of the width of the high-voltage protection plate 15 and the first thickness of the slide rails 101 on both sides is less than the distance between the first side panel 11 and the second side panel 12, to avoid friction from the slide rails 101 when the high-voltage protection plate 15 rotates within the cabinet 10. In this embodiment, the first thickness is less than the first gap, such that the distance between the ends of the two limiting springs 161 near the back panel 13 is less than the width of the high-voltage protection plate 15. When the high-voltage protection plate 15 rotates to a state parallel to the back panel 13, the limiting springs 161 can engage with the high-voltage protection plate 15, allowing the high-voltage protection plate 15 to shield the connector 14.

[0074] In the embodiments of this application, such as Figure 5 As shown, within the installation area of ​​a converter module 20, a slide rail 101 can be disposed between the first hinge position and the limiting spring 161 on the first side panel 11, or between the second hinge position and the limiting spring 161 on the second side panel 12. In this way, the installed converter module 20 can be supported by the slide rail 101, and the slide rail 101 disposed between the hinge position and the limiting spring 161 can also balance the stress on the converter module 20 after it is installed in the cabinet 10, improving power supply stability.

[0075] Figure 6 This is a schematic diagram of another converter module provided in an embodiment of this application.

[0076] In some embodiments of this application, because the distance between the two limiting springs 161 near the end of the back panel 13 is less than the width of the high-voltage protection plate 15, when the maintenance personnel install the converter module 20 into the cabinet 10 without exerting other influence on the cabinet 10, the snap-fit ​​state between the high-voltage protection plate 15 and the limiting component 16 cannot be released, increasing the risk of damage to the high-voltage protection plate 15. Furthermore, when the maintenance personnel pull the converter module 20 out of the cabinet 10, the high-voltage protection plate 15 will be blocked by the limiting springs 161 and cannot return to the snap-fit ​​state with the limiting component 16.

[0077] like Figure 6As shown, the converter module 20 is provided with at least one sliding bar 22 on the side facing the first side panel 11 and the side facing the second side panel 12, respectively. The sliding bar 22 protrudes from the surface of the converter module 20. The width of the converter module 20 and the sliding bar 22 is less than the distance between the first side panel 11 and the second side panel 12, so that the converter module 20 can be installed into the cabinet 10 through the slide rail 101.

[0078] Meanwhile, the combined width of the converter module 20 and the sliding strip 22 is greater than the width of the high-voltage protection plate 15. When the converter module 20 is installed in the cabinet 10, the sliding strip 22 can abut against the limiting spring 161 respectively, so that the distance between the ends of the two limiting springs 161 closest to the back panel 13 is greater than the width of the high-voltage protection plate 15. The high-voltage protection plate 15 can rotate as the converter module 20 is pushed forward, thus removing the obstruction of the connector 14.

[0079] Figure 7 This is a schematic diagram of the converter module provided in this application being installed in a cabinet.

[0080] like Figure 7 As shown in (a), before the maintenance personnel install the converter module 20, the high-voltage protection plate 15 and the limiting component 16 are in a snap-fit ​​state. At this time, the high-voltage protection plate 15 is set parallel to the back panel 13, blocking the plug 14 set on the back panel 13 and reducing the risk of high-voltage electric shock.

[0081] Then, as the converter module 20 is advanced within the rack 10, such as Figure 7 As shown in (b), the sliding bar 22 abuts against the limiting springs 161 on both sides, thereby releasing the locking between the limiting springs 161 and the high-voltage protection plate 15. At this time, as the advancement progresses, the sliding block 21 can transmit the thrust for installing the converter module 20 to the high-voltage protection plate 15, allowing the high-voltage protection plate 15 to rotate towards the back panel 13, releasing the obstruction and protection of the connector 14, so that the converter module 20 can be installed in the cabinet 10, for example... Figure 7 The structure shown in (c) is as follows.

[0082] Correspondingly, the process of maintenance personnel unplugging converter module 20 from rack 10 is the reverse process of maintenance personnel installing converter module 20. For example... Figure 7 As shown in (c), before the maintenance personnel remove the converter module 20, the high-voltage protection plate 15 is affected by the thrust during the installation process and is located on the side of the converter module 20 near the upper end of the cabinet 10. The converter module 20 is electrically connected to the connector 14.

[0083] Then, as the converter module 20 is pulled out of the rack 10, as... Figure 7As shown in (b), because the converter module 20 no longer provides support for the high-voltage protection plate 15, as the converter module 20 is pulled out, the high-voltage protection plate 15 rotates away from the back panel 13 due to gravity. At this time, the sliding bar 22 is still in contact with the limiting spring 161, and the distance between the limiting springs 161 is greater than the width of the high-voltage protection plate 15. When the high-voltage protection plate 15 rotates to be perpendicular to the back panel 13, the contact between the sliding bar 22 and the limiting spring 161 is released as the converter module 20 is pulled out, thereby reducing the distance between the limiting springs 161 and the back panel 13 until the limiting springs 161 are engaged with the high-voltage protection plate 15. Figure 7 As shown in (a), at this time, the high-voltage protection plate 15 can shield the connector 14, reducing the risk of electric shock to the live connector 14.

[0084] It should be understood that the above-described process of installing and removing the converter module 20 is only an example in the embodiments of this application. When there are differences in the structure between the converter module 20 and the cabinet 10, the process of installing and removing the converter module 20 will change accordingly, which will not be described in detail here.

[0085] It should be understood that, in some embodiments of this application, because both the sliding block 21 and the sliding bar 22 in the converter module 20 protrude from the surface of the converter module 20, by... Figure 7 As shown in the diagram, the protrusions of the slider 21 and slider 22 include the direction toward the back panel 13. Therefore, the connector 14 provided on the back panel 13 is also protruding so that the connector 14 can be electrically connected to the input or output of the converter module 20.

[0086] Furthermore, the hinge position of the high-voltage protection plate 15 may be provided with a limiting mechanism. By providing a protrusion on the side away from the back panel 13 at the first hinge position and the second hinge position, the high-voltage protection plate 15 can be prevented from being affected by external forces and from continuing to rotate away from the back panel 13 while remaining parallel to it.

[0087] Through the above description of the embodiments, those skilled in the art can clearly understand that, for the sake of convenience and brevity, only the division of the above functional modules is used as an example. In actual applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different modules to complete all or part of the functions described above.

Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.

[0089] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
