Description

Technical Field

[0001] This utility model relates to the field of switch accessories technology, specifically to a high-temperature and high-pressure resistant Type A switch module. Background Technology

[0002] In modern power systems, Type A switch modules serve as critical control and protection devices, and their performance stability and safety directly impact the reliable operation of the entire power system. This is especially true in extreme environments with high temperature and high pressure, where the performance and safety of the switch modules become paramount.

[0003] While traditional Type A switch modules can meet general power control needs, their performance is often severely affected in extreme environments such as high temperature and high pressure, potentially leading to equipment failure or safety accidents. Traditional switch modules lack structural flexibility, often requiring complete disassembly and replacement in case of failure. This not only increases maintenance costs but also disrupts the normal operation of the power system. Furthermore, their design and material selection do not adequately consider explosion-proof performance. In high-temperature and high-pressure environments, internal faults can trigger explosions or ruptures, posing a serious threat to equipment and personnel safety. Utility Model Content

[0004] The purpose of this invention is to provide a high-temperature and high-pressure resistant Type A switch module to solve the problems of inconvenient maintenance and poor protection performance of existing Type A switch modules mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The high-temperature and high-pressure resistant Type A switch module consists of a three-layer spliced ​​inner shell, middle frame, and top frame;

[0007] The inner housing is equipped with several sets of evenly spaced switch springs, and a high-temperature and high-pressure resistant protective partition is installed between each pair of adjacent switch springs. The top surface of the inner housing is provided with an explosion-proof base plate.

[0008] An explosion-proof inner core is installed on the middle frame. The explosion-proof inner core and the middle frame are integrally formed. Several evenly spaced slots are installed on the edge of the explosion-proof inner core. The bottom surface of the explosion-proof inner core has an embedding groove that is adapted to the size of the explosion-proof base plate and is snapped together.

[0009] The top frame is equipped with a smooth-polished explosion-proof face shield, and the bottom surface of the explosion-proof face shield is equipped with buckles that are the same number as the slots, corresponding in position, and engaging with each other.

[0010] Preferably, the protective partition, explosion-proof base plate, explosion-proof inner core and explosion-proof face shield are all made of insulating PP wrapped around the surface of a cast copper alloy sheet, and the thickness of the inner cast copper alloy sheet is 2-4mm, and the thickness of the insulating PP is 1-3mm.

[0011] Preferably, the switch spring is made of copper or stainless steel and has a thickness of 1-2 mm.

[0012] Preferably, the explosion-proof inner core is embedded with button pressure plates that are the same number and position as the switch springs.

[0013] Preferably, the button plate is made of high-temperature and high-pressure resistant PP material wrapped around a metal core, and has a thickness of 3-5mm.

[0014] Preferably, the top edge of the middle frame is provided with two sets of positioning grooves, and the bottom of the top frame is provided with positioning posts that are the same number as the positioning grooves, corresponding in position, and of the same size and are plugged in.

[0015] Preferably, the edge of the embedding groove is fitted with a number of uniformly spaced reinforcing ribs.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] This high-temperature and high-pressure resistant Type A switch module features a three-layer splicing design consisting of an inner shell, a middle frame, and a top frame. This design not only improves the stability of the entire switch module but also facilitates assembly and disassembly. When a part needs repair or replacement, the entire module can be installed without disassembling it, improving maintenance efficiency. The high-temperature and high-pressure resistant protective partition effectively isolates and prevents heat conduction and electrical spark interference between adjacent switch contacts, enhancing the module's safety and reliability. The explosion-proof base plate and explosion-proof inner core design effectively prevent potential explosions or ruptures under high-temperature and high-pressure environments, protecting the internal structure of the switch module and the safety of the user. The explosion-proof face shield not only effectively prevents external substances or moisture from entering the switch module but also reduces friction and resistance with the external environment due to its smooth surface finish, thereby reducing heat and wear caused by friction.

[0018] In this high-temperature and high-pressure resistant Type A switch module, the explosion-proof inner core is embedded with button pressure plates that are the same number and position as the switch springs. The button pressure plates are made of high-temperature and high-pressure resistant PP material wrapped around the metal inner core, so that when the user operates the switch, he / she can directly act on the button pressure plates to control the on / off state of the switch springs. The high-temperature and high-pressure resistant PP material ensures the stability of the button pressure plates in extreme environments.

[0019] In this high-temperature and high-pressure resistant Type A switch module, two sets of positioning slots are provided on the top edge of the middle frame. The bottom of the top frame is equipped with positioning posts that are the same number as the positioning slots, corresponding in position, and of the same size, and are plugged in. Through the plugging in of the positioning slots and positioning posts, the assembly between the middle frame and the top frame becomes simpler, faster, and more accurate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "center", "vertical", "horizontal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] High-temperature and high-pressure resistant Type A switch modules, such as Figures 1-3 As shown, the device includes a three-layered spliced ​​inner shell 10, a middle frame 20, and a top frame 30. The inner shell 10 contains several sets of evenly spaced switch springs 11, with a high-temperature and high-pressure resistant protective partition 12 between each pair of adjacent sets of switch springs 11. An explosion-proof base plate 13 is provided on the top surface of the inner shell 10. An explosion-proof inner core 21 is installed on the middle frame 20, forming an integral structure with the middle frame 20. Several evenly spaced slots 22 are installed along the edge of the explosion-proof inner core 21, and an embedding groove 26, matching the size of the explosion-proof base plate 13, is provided on the bottom surface of the explosion-proof inner core 21. A smoothly polished explosion-proof face shield 31 is installed on the top frame 30, with buckles 32 on the bottom surface of the face shield 31 in the same number and corresponding positions as the slots 22, engaging with the inner shell 10. The three-layer splicing design of the middle frame 20 and the top frame 30 not only improves the stability of the entire switch module, but also facilitates assembly and disassembly. When a part needs to be repaired or replaced, it is not necessary to disassemble the entire module, which improves maintenance efficiency. The high-temperature and high-pressure resistant protective partition 12 can effectively isolate and prevent heat conduction and electrical spark interference between adjacent switch springs, improving the safety and reliability of the module. The design of the explosion-proof base plate 13 and the explosion-proof inner core 21 can effectively prevent explosions or cracks that may occur under high temperature and high pressure environments, protecting the internal structure of the switch module and the safety of users. The explosion-proof cover 31 can not only effectively prevent external substances or moisture from entering the switch module, but its smooth surface also reduces friction and resistance with the external environment, thereby reducing the heat and wear generated by friction.

[0031] Furthermore, the protective partition 12, explosion-proof base plate 13, explosion-proof inner core 21, and explosion-proof face shield 31 are all made of insulating PP wrapped around the surface of a cast copper alloy sheet. The thickness of the inner cast copper alloy sheet is 2-4mm, and the thickness of the insulating PP is 1-3mm. This not only provides resistance to high temperature and high pressure, but also effectively prevents direct contact of current or voltage, enhancing the safety performance of the module. At the same time, the cast copper alloy sheet provides mechanical strength, while the insulating PP layer ensures electrical isolation.

[0032] The switch spring 11 is made of copper or stainless steel with a thickness of 1-2mm, providing good conductivity and elasticity to maintain stable performance during high-frequency switching operations. The appropriate thickness also ensures the spring's strength and durability.

[0033] Specifically, the explosion-proof inner core 21 is embedded with button pressure plates 24, which are the same number and corresponding in position as the switch springs 11. The button pressure plates 24 are made of high-temperature and high-pressure resistant PP material wrapped around the metal inner core, and the thickness is 3-5mm. This allows the user to directly act on the button pressure plates 24 when operating the switch, thereby controlling the on / off state of the switch springs 11. The high-temperature and high-pressure resistant PP material ensures the stability of the button pressure plates 24 in extreme environments.

[0034] In addition, two sets of positioning grooves 23 are provided on the top edge of the middle frame 20, and positioning posts 33 are installed at the bottom of the top frame 30. These posts are the same number as the positioning grooves 23, corresponding in position, and of the same size, and are plugged in to fit together. Through the plugging and fitting of the positioning grooves 23 and the positioning posts 33, the assembly between the middle frame 20 and the top frame 30 becomes simpler, faster and more accurate.

[0035] It is worth noting that the edge of the embedding groove 26 is equipped with several uniformly spaced reinforcing ribs 27. The design of the reinforcing ribs 27 enhances the mechanical strength of the embedding groove 26 and its surrounding area, enabling the explosion-proof inner core 21 to better maintain its shape and structural stability when subjected to external impact or pressure. This design improves the durability and reliability of the module.

[0036] The working principle of this high-temperature and high-pressure resistant Type A switch module is as follows: The operator assembles the inner housing 10, middle frame 20, and top frame 30, installs the switch module in the designated position, and ensures correct connection to the external circuit and control system. The operator regularly observes the switch module's operating status, performs periodic inspections and maintenance to ensure continuous and stable operation. If any part needs repair or replacement, the three-layer splicing design allows for convenient partial disassembly and replacement without disassembling the entire module. When replacing parts, ensure that the same or compatible replacement parts are used and follow the correct installation procedures.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
