[0002] In modern power systems, high-voltage switchgear is an indispensable power equipment, which is widely used in power transmission and distribution. High-voltage switchgear is usually used to control, protect and detect power systems to ensure the safe and stable operation of power systems. However, with the increasing requirements for safety performance of power systems, traditional high-voltage switchgear has shown some shortcomings in power protection, especially when using battery packs as backup power sources, the potential safety hazards are particularly prominent.

[0003] In the traditional design of high-voltage switchgear, the power supply is usually installed directly inside the cabinet, but there is a relative lack of protection measures for the power supply itself. This design ignores the safety risks of the battery pack in emergency situations, such as external fires or abnormal situations such as short circuits inside the high-voltage switchgear. As a chemical power source, the battery pack itself is flammable and explosive. Under abnormal circumstances, if the battery pack catches fire, it will not only seriously threaten the safety of personnel, but may also cause the paralysis of the power system, bringing serious consequences to society.

[0004] Therefore, how to ensure the normal heat dissipation of the power supply when the power supply is working normally, and at the same time protect the safety of the power supply when the temperature of the high-voltage switch cabinet is abnormal, has become a technical problem that needs to be solved urgently.

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0034] like Figures 1 to 5 As shown, in order to achieve the above-mentioned purpose, the utility model proposes a power supply protection device for a high-voltage switch cabinet, comprising:

[0035] The housing 10 has a receiving cavity for receiving a power source;

[0036] A cover 20, which covers the opening of the housing 10;

[0037] A driving assembly connected to the cover body 20;

[0038] A temperature detection member 30 connected to the cover 20 and used to detect the temperature inside the high-voltage switch cabinet; and

[0039] The control unit 50 controls the driving assembly to drive the cover 20 to open or close the opening of the housing 10 according to the temperature detected by the temperature detecting member 30 .

[0040] Specifically, the housing 10 is the external structure of the power protection device, and the housing 10 is made of metal (such as aluminum alloy or stainless steel). The housing 10 has a receiving cavity inside for receiving a power source, such as a battery pack.

[0041] The cover 20 is a component covering the opening of the housing 10. The cover 20 can seal the housing 10 to protect the internal power supply from external influences. The material of the cover 20 can be the same as that of the housing 10 to ensure the overall mechanical and thermal stability. The cover 20 is connected to the housing 10 by a hinge, a telescopic cylinder or other connection methods to facilitate opening and closing.

[0042] The driving assembly is connected to the cover 20 and is responsible for driving the cover 20 to open or close according to the command of the control unit 50. The driving assembly can be an electric motor, a pneumatic or hydraulic system, etc. The specific selection depends on the size of the housing 10 and the required opening and closing torque, which is not specifically limited here.

[0043] The temperature detection element 30 is a sensor installed inside the cover 20 or other appropriate positions for real-time monitoring of the temperature inside the high-voltage switch cabinet. The temperature detection element 30 can be a thermocouple, a thermal resistor or other types of temperature sensors, and the temperature detection element 30 is electrically connected to the control unit 50.

[0044] The control unit 50 is the core of the power protection device. The control unit 50 receives the signal from the temperature detection element 30. When it is detected that the temperature does not exceed the preset threshold, the control unit 50 will issue a command to the drive component to drive the cover 20 to open to achieve rapid heat dissipation. When it is detected that the temperature exceeds the preset threshold, the control unit 50 will issue a command to the drive component to drive the cover 20 to close to protect the power supply.

[0045] The above technical solution can effectively prevent the power supply from burning due to the risk of fire and explosion of the high-voltage switch cabinet by intelligently monitoring the temperature of the high-voltage switch cabinet and responding in time. When the power supply is working normally, the normal heat dissipation of the power supply is guaranteed, and when the temperature of the high-voltage switch cabinet is abnormal, the safety of the power supply can be protected.

[0046] In one embodiment of the present application, a slot 15 is provided on the side wall of the shell 10 along the top to bottom direction of the side wall, and a filter net 21 is provided on the peripheral side of the shell 10. When the cover body 20 closes the opening of the shell 10, the filter net 21 is received in the slot 15.

[0047] Specifically, the slot 15 is located on the side wall of the housing 10, and its function is to provide a mounting position for the filter 21, and also facilitate the removal and replacement of the filter 21. The design of the slot 15 enables the filter 21 to be firmly positioned in the housing 10, providing additional functionality without affecting the appearance and compactness of the device.

[0048] The filter 21 is mounted on the side of the housing 10 and stably received in the housing 10 through the slot 15. The filter 21 is made of a metal mesh or synthetic fiber mesh with high air permeability, which can effectively prevent dust and impurities from entering the protective device, while allowing air circulation to help dissipate heat inside.

[0049] By adopting the above technical solution, the filter 21 can effectively prevent dust, small insects and other impurities from invading the interior of the housing 10, thereby reducing the impact of these impurities on the power supply.

[0050] In one embodiment of the present application, when the cover 20 opens the opening of the shell 10 , the distance between the peripheral side of the cover 20 and the corresponding position on the shell 10 is smaller than the height of the filter 21 .

[0051] By adopting the above technical solution, when the cover body 20 opens the opening of the shell 10, the distance between the peripheral side of the cover body 20 and the corresponding position on the shell 10 is smaller than the height of the filter 21, thereby ensuring that the filter 21 can cover the space between the peripheral side of the cover body 20 and the corresponding position on the shell 10, thereby improving the protection effect.

[0052] In one embodiment of the present application, a mounting seat 11 is provided on the outer wall of the housing 10 near the opening, and a "mouth"-shaped or "T"-shaped support frame 12 is connected to the mounting seat 11. An insulating socket 13 is provided on the top of the support frame 12, and a conductive seat 14 that can be connected to a load is provided in the insulating socket 13;

[0053] The cover 20 is provided with a support plate 22 , and the support plate 22 is connected with a conductive column 23 that can be connected to the power supply in the housing 10 . The conductive column 23 can maintain a connected or disconnected state with the movement of the cover 20 .

[0054] Specifically, a mounting seat 11 is provided near the opening of the outer wall of the housing 10. The mounting seat 11 provides a stable mounting point for the support frame 12. The mounting seat 11 is made of a high-strength, corrosion-resistant material, such as aluminum alloy or stainless steel, to ensure the stability and durability of the entire device.

[0055] The "mouth" or "T" shaped support frame 12 is installed on the mounting seat 11, and the mounting seat 11 provides support for the insulating socket 13. According to design requirements, the support frame 12 can be in various shapes, but the "mouth" or "T" shape is the optimal structure. The "mouth" or "T" shaped support frame 12 can provide stable and reliable support for the insulating socket 13.

[0056] The insulating socket 13 is installed on the top of the support frame 12, and a conductive seat 14 is provided inside the insulating socket 13 to be connected to the load. The material used for the insulating socket 13 needs to have good insulation performance, such as PVC or other high-insulation plastics. The conductive seat 14 needs to be made of a material with good conductivity (such as copper or aluminum) to ensure smooth power transmission.

[0057] A support plate 22 is provided on the cover 20. The support plate 22 and the cover 20 may be integrally formed or fixedly connected, and a conductive column 23 is connected to the support plate 22. The conductive column 23 is designed to be connected to the conductive seat 14 in the insulating socket 13 when the cover 20 is opened to form a current path between the power supply and the external load.

[0058] As the cover 20 is closed, the conductive column 23 moves downward and is disconnected from the conductive seat 14 in the insulating socket 13, thereby achieving a disconnected state; when the cover 20 is opened, the conductive column 23 moves away and is electrically connected to the conductive seat 14, thereby achieving a connected state.

[0059] By adopting the above technical solution, the design of the conductive seat 14 and the conductive column 23 ensures the safety of the power connection, facilitates the rapid connection and disconnection of the power supply, and further improves the protection of the power supply when the temperature of the high-voltage switch cabinet is abnormal.

[0060] In one embodiment of the present application, when the support frame 12 is in a "mouth" shape, a first sealing plate 62 is provided at the opening of the support frame 12 away from the housing 10;

[0061] A second sealing plate 61 is disposed on one side of the cover body 20 close to the support plate 22 . When the cover body 20 closes the opening of the shell 10 , the second sealing plate 61 covers the opening of the support frame 12 close to the shell 10 .

[0062] Specifically, when the support frame 12 is in a "mouth" shape, a first sealing plate 62 is provided at the opening of the support frame 12 away from the housing 10. The first sealing plate 62 is used to provide primary sealing protection for the support frame 12 and the conductive column 23 therein to prevent the intrusion of dust, moisture and other impurities.

[0063] A second sealing plate 61 is provided on one side of the cover 20 close to the support plate 22 . When the cover 20 is closed, the second sealing plate 61 corresponds to the first sealing plate 62 on the support frame 12 , thereby providing additional sealing protection for the two openings of the support frame 12 .

[0064] By adopting the above technical solution, by introducing the design of the first sealing plate 62 and the second sealing plate 61, dust, moisture and other components that may damage the support frame 12 are effectively blocked, ensuring the cleanliness and safety of the internal environment of the support frame 12.

[0065] In one embodiment of the present application, a fixing frame 16 for supporting the power supply is provided at the bottom of the accommodating cavity.

[0066] By adopting the above technical solution, the fixing frame 16 provides a stable supporting platform for the power supply, which can effectively reduce the impact of external vibration or impact on the power supply and protect the power supply from damage, especially during movement or when the external environmental conditions are harsh.

[0067] In one embodiment of the present application, the fixing frame 16 is provided with a plurality of through slots 17 arranged in an array.

[0068] With the above technical solution, the array formed by the plurality of through slots 17 can effectively increase air circulation, thereby improving the ventilation and heat dissipation capacity of the entire system. This is critical for extending the life of the power supply and maintaining its continuous and stable operating performance, because overheating may cause damage or failure of electronic components.

[0069] In one embodiment of the present application, the driving assembly includes:

[0070] A guide tube 41, a first end of which is connected to the bottom of the accommodating cavity;

[0071] A guide post 42, wherein a first end of the guide post 42 is connected to the bottom of the cover body 20, and a second end of the guide post 42 is inserted into the guide tube 41; and

[0072] The driving member is disposed in the guide cylinder 41 , and the telescopic shaft of the driving member is connected to the second end of the guide column 42 , so as to drive the guide column 42 to reciprocate along the length direction of the guide cylinder 41 .

[0073] Specifically, the guide cylinder 41 is a hollow cylindrical structure, and the first end is fixedly connected to the bottom of the accommodating cavity. The guide cylinder 41 serves as a guide and receiving element, and provides an axial path for the guide column 42 to be inserted and slid.

[0074] The guide post 42 is a relatively slender rod-shaped component, the first end of which is connected to the bottom of the cover 20, and the second end of which can be inserted into the guide cylinder 41. The matching design of the guide post 42 and the guide cylinder 41 provides a stable guiding force for the cover 20, ensuring that the up and down movement direction of the cover 20 is consistent and smooth.

[0075] The driving member is located inside the guide cylinder 41, and the telescopic shaft of the driving member is connected to the second end of the guide column 42. The driving member can be driven by different driving modes such as electric, pneumatic or hydraulic according to design requirements. The function of the driving member is to control the guide column 42 to reciprocate along the length direction of the guide cylinder 41, that is, to push the cover body 20 to open or close.

[0076] By adopting the above technical solution, the driving assembly realizes a smooth and precise opening and closing action of the cover body 20 by cooperating with the guide column 42 and the guide cylinder 41, thereby minimizing vibration or deflection during movement.

[0077] In one embodiment of the present application, a heat insulation layer is provided on the inner wall of the accommodating cavity.

[0078] By adopting the above technical solution, the heat insulation layer can reduce the influence of the heat outside the accommodating cavity on the power supply, maintain it in a suitable temperature environment, and avoid damage to the power supply.

[0079] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
