Description

Technical Field

[0001] This utility model relates to the field of power supply system technology, and more specifically, to a dual power transfer switch of a module with an integrated layout of contact system and magnetic system. Background Technology

[0002] In modern power supply systems, dual-power transfer switches are widely used in industrial, commercial, and civil buildings as key devices to ensure the continuity and stability of power supply. When the main power supply fails or is interrupted, the dual-power transfer switch can quickly switch to the backup power supply to ensure continuous power supply to critical loads and avoid economic losses and safety hazards caused by power outages.

[0003] Currently, dual-power transfer switch technology is constantly evolving. For example, patent application number CN201911405068.7 discloses a dual-power transfer switch, belonging to the field of low-voltage electrical technology. It includes a breaking unit with a contact pressure compensation structure. Through clever design of the flexible connection's electrodynamic direction, it improves the contact pressure and dynamic-thermal stability during the closing state. However, this solution still has certain limitations. Its contact system and magnetic system are not integrated, resulting in a relatively loose overall structure. This not only occupies more installation space but also increases the installation, transportation, and storage costs of the equipment to some extent. Furthermore, the magnetic system uses a traditional design without structural optimization, making miniaturization and integration difficult and limiting the product's application in more scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a dual power transfer switch with an integrated layout of the contact system and the magnetic system, in order to solve the problem mentioned in the background art that the contact system and the magnetic system are not integrated, the overall structure is relatively loose, which not only occupies more installation space, but also increases the installation, transportation and storage costs of the equipment to a certain extent.

[0005] To achieve the above objectives, this utility model provides a dual power transfer switch with an integrated layout of contact system and magnetic system, including a control and operation module and one or more sets of contact modules. The contact modules are connected to the control and operation module through a transmission connector. The contact modules are provided with at least three wiring terminals on their exterior. The control and operation module is provided with at least one control interface terminal.

[0006] This dual-power transfer switch forms the basic architecture of the control and operation module and the contact module, with power transmission between them achieved through a transmission connector. The contact module has at least three external terminals for connecting the power supply and load lines; the control and operation module has at least one control interface terminal for connecting external control signals or power supplies, thereby enabling control and power supply to the dual-power transfer switch.

[0007] As a preferred embodiment of this utility model, the control and operation module includes a handle, a power indicator drive component, a connecting rod, a transmission shaft, a power interface terminal, and a housing. The housing includes a base and a cover. The handle and the transmission shaft are connected by a connecting rod, and the power interface terminal is located on both sides of the housing.

[0008] Within this control and operation module, the handle is connected to the drive shaft via a linkage. When the operator operates the handle, its movement is transmitted to the drive shaft through the linkage, thus converting and transmitting mechanical power. Power interface terminals are located on both sides of the housing for connecting to an external power supply line to provide power to the entire control and operation module. The housing uses a base and cover structure to protect the internal components.

[0009] As a preferred embodiment of this utility model, the upper end of the handle passes through the power indicator driver, and the left and right swing of the handle can drive the power indicator driver to move left and right. Power indicator relays are installed at both ends of the control and operation module near the power indicator driver. The left and right movement of the power indicator driver drives the power indicator relays at both ends to open and close, thereby realizing the indication of power on and off.

[0010] This design involves passing the upper end of the handle through the power indicator driver. When the handle swings left or right, it causes the power indicator driver to move synchronously left and right. Power indicator relays are installed at both ends of the control and operation module near the power indicator driver. The movement of the power indicator driver triggers the opening and closing of the power indicator relays at both ends. The open and closed states of the power indicator relays correspond to different power on / off conditions, thus indicating the power on / off status.

[0011] As a preferred embodiment of this utility model, the contact module includes a dual power supply conversion module, which includes a contact system, an arc extinguishing system, a wiring system, and a magnetic drive system. The magnetic drive system includes a push rod, a moving iron core, a winding, and a magnetic yoke. The magnetic drive system is connected to the contact system through the push rod to drive the contact system to switch. The arc extinguishing system is located on the upper part of the contact system and is used to extinguish the electric arc generated by the contact system during the switching process.

[0012] This dual-power conversion module in the contact module integrates the contact system, arc-extinguishing system, wiring system, and magnetic drive system. The magnetic drive system is connected to the contact system via a push rod. When the windings of the magnetic drive system are energized, a magnetic field is generated, attracting the moving iron core. The moving iron core drives the push rod to switch the contact system, thus achieving dual-power conversion. The arc-extinguishing system is located above the contact system. When an arc is generated during the contact system switching process, the arc-extinguishing system quickly extinguishes the arc using physical or chemical means, preventing damage to the contacts and equipment.

[0013] As a preferred embodiment of this utility model, the contact system includes a moving contact, a transmission shaft, a stationary contact, a drive rod, a positioning conductive plate, a positioning shaft, a contact pressure retaining member, and a contact final pressure guaranteeing member; the moving contact is connected to the transmission shaft, the positioning conductive plate is fixed by the positioning shaft, the positioning conductive plate is a plurality of parallel conductive plates, the moving contact is located between the positioning conductive plates and is pressed and positioned by the contact pressure retaining member, the contact final pressure guaranteeing member is disposed between the moving contact and the inner side of the transmission shaft, one end of the drive rod is connected to the moving contact, and the other end is connected to the push rod of the magnetic drive system.

[0014] In this contact system, the moving contact is connected to the drive shaft, and the positioning conductive plates are fixed by the positioning shaft. Multiple parallel positioning conductive plates form a fixed structure. The moving contact is located between the positioning conductive plates. A contact pressure retainer (spring structure) applies pressure to the moving contact, pressing it between the positioning conductive plates to ensure good electrical contact. A contact final pressure guaranteeing element (spring structure) is located between the moving contact and the inner side of the drive shaft, providing sufficient pressure when the moving contact and stationary contact are closed to ensure contact stability. One end of the drive rod is connected to the moving contact, and the other end is connected to the push rod of the magnetic drive system, transmitting the power of the magnetic drive system to the moving contact to realize the contact switching action.

[0015] As a preferred embodiment of this utility model, the contact pressure holding member is a spring structure, used to maintain the contact pressure between the moving contact and the positioning conductive plate, and the contact final pressure guarantee member is a spring structure, used to ensure that the pressure is maintained when the moving contact and the stationary contact are closed.

[0016] This design incorporates spring structures for both the contact pressure retainer and the final contact pressure guarantee, utilizing the elastic deformation of the spring to generate pressure. Under normal conditions, the contact pressure retainer uses its own elasticity to press the moving contact firmly between the positioning conductive plates, ensuring a stable contact pressure between the moving contact and the positioning conductive plates. During the closing process between the moving and stationary contacts, the final contact pressure guarantee compresses the spring as the moving contact moves, generating gradually increasing pressure to ensure the required contact pressure is achieved when the moving and stationary contacts close.

[0017] As a preferred embodiment of this utility model, the wiring system has at least three parts, and each wiring system includes a load terminal. The magnetic yoke of the magnetic drive system is a shared structure of two magnetic systems arranged in series, and the two magnetic systems share a moving iron core and a push rod.

[0018] This setup has at least three wiring systems, each including a load terminal for connecting the load line. The magnetic drive system's yoke uses a shared structure of two magnetic systems connected in series, sharing a moving iron core and a push rod. When the winding of one magnetic system is energized, it generates a magnetic field that attracts the shared moving iron core, which in turn drives the push rod to switch the contact system. The other magnetic system is energized when a reverse switching is required.

[0019] As a preferred embodiment of this utility model, the magnetic drive system is a compact bidirectional drive magnetic system. By energizing different windings, the drive function of the push rod moving left and right is realized. When the moving iron core is on the right, the left winding is energized and the moving iron core moves to the left; conversely, when the moving iron core is on the left, the right winding is energized and the moving iron core moves to the right.

[0020] This magnetic drive system is a compact, bidirectional drive magnetic system that achieves the left and right movement of the push rod by energizing different windings. When the moving iron core is on the right, energizing the left winding generates a magnetic field that attracts the moving iron core to the left, driving the push rod to the left and achieving the corresponding switching of the contact system. Conversely, when the moving iron core is on the left, energizing the right winding generates a magnetic field that attracts the moving iron core to the right, driving the push rod to the right and completing the reverse switching of the contact system.

[0021] As a preferred embodiment of this utility model, one end of the transmission connector is connected to the transmission shaft of the control and operation module, and the other end is connected to the transmission shaft of the contact module, for transmitting the operating power of the control and operation module to the contact module. Adjacent contact modules are connected to each other through the transmission shaft.

[0022] This configuration involves connecting one end of the transmission connector to the drive shaft of the control and operation module and the other end to the drive shaft of the contact module. This transmits the operating power from the control and operation module from the drive shaft to the drive shaft of the contact module, thereby driving the contact system to operate. Adjacent contact modules are interconnected via drive shafts. When one contact module operates, it drives adjacent contact modules to operate synchronously via the drive shaft, enabling coordinated operation of multiple contact modules.

[0023] As a preferred embodiment of this utility model, control interface terminals are installed on both sides of the top of the control and operation module.

[0024] This setting controls the installation of control interface terminals on both sides of the top of the operation module, which are used to connect external control devices or signal sources. The external control signal is transmitted to the inside of the control and operation module through the control interface terminals to achieve remote control, automatic control or linkage control with other devices for the dual-power transfer switch.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0026] 1. In the dual-power transfer switch with a module having an integrated layout of the contact system and the magnetic system, the contact module and the control and operation module are connected by a transmission connecting member, and the contact module integrates a contact system, an arc extinguishing system, a wiring system and a magnetic drive system, achieving a high degree of integration of the overall structure. This integrated layout significantly reduces the space occupied by the product, effectively reduces the costs during installation, transportation and storage of the equipment, and is also convenient for application in scenarios with limited space.

[0027] 2. In the dual-power transfer switch with a module having an integrated layout of the contact system and the magnetic system, the magnetic drive system adopts a common structure of two magnet systems arranged in series, sharing a moving iron core and a push rod, and is designed as a compact bidirectional drive magnetic system.

It can drive the contact system to switch more quickly and stably, enhancing the overall performance of the dual-power transfer switch.

[0028] 3. In the dual-power transfer switch with a module having an integrated layout of the contact system and the magnetic system, in the contact system, the moving contact is pressed between the positioning conductive plates by a contact pressure maintaining member, and a contact final pressure ensuring member is used to ensure the pressure when the moving contact and the static contact are closed. The contact pressure maintaining member and the contact final pressure ensuring member with a spring structure can effectively maintain the contact pressure between the moving contact and related components, avoid poor contact of the contacts and the generation of arcs, significantly improve the dynamic and thermal stability of the dual-power transfer switch, and enhance the reliability of the equipment operation.

[0029] 4. In the dual-power transfer switch with a module having an integrated layout of the contact system and the magnetic system, in the control and operation module, the handle is传动连接 with the transmission shaft through a connecting rod. Operating the handle can drive the contact module to act, and the operation is simple and convenient. At the same time, the upper end of the handle passes through the power supply identification driving member, and the left and right swing of the handle drives the power supply identification driving member to move, thereby controlling the opening and closing of the power supply identification relay, realizing an intuitive power supply opening and closing identification, facilitating the operator to timely grasp the operation state of the equipment, and reducing the difficulty of equipment maintenance and management.

[0030] It should be noted that there is an error in the original text where "手柄通过连杆与传动轴传动连接" is not fully translated. The correct translation should be "The handle is connected to the transmission shaft through a connecting rod for transmission". The above translation has been corrected accordingly.5. In the modular dual-power transfer switch with the contact system and magnetic system integrated layout, a modular design is adopted. One or more sets of contact modules cooperate with the control and operation modules, and adjacent contact modules are connected to each other through a transmission shaft. This design gives the product good scalability and versatility, and the number of contact modules can be flexibly configured according to actual needs to meet the application requirements of different power scenarios, thereby improving the product's market adaptability.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0040] This utility model provides a dual power supply transfer switch for a module with an integrated layout of contact system and magnetic system, such as... Figure 1 As shown, it includes a control and operation module 1 and one or more sets of contact modules 2. The contact modules 2 and the control and operation module 1 are connected by a transmission connector 3. At least three wiring terminals 4 are provided on the outside of the contact modules 2. The control and operation module 1 is provided with at least one control interface terminal 5.

[0041] This utility model's dual-power transfer switch comprises a control and operation module 1 and a contact module 2, with power transmission between them achieved through a transmission connector 3. The contact module 2 has at least three external terminals 4 for connecting the power supply and load lines; the control and operation module 1 has at least one control interface terminal 5 for connecting external control signals or power supplies, thereby enabling control and power supply to the dual-power transfer switch. This modular design makes the dual-power transfer switch structurally clear and functionally defined, facilitating installation, maintenance, and repair. Furthermore, by increasing or decreasing the number of contact modules 2, it can flexibly adapt to different power load requirements, improving the product's versatility and expandability to meet diverse application scenarios.

[0042] In this embodiment, as Figure 1 , Figure 2 As shown, the control and operation module 1 includes a handle 11, a power indicator drive 12, a connecting rod 13, a drive shaft 14, a power interface terminal 15, and a housing 16. The housing 16 includes a base and a cover. The handle 11 and the drive shaft 14 are connected by the connecting rod 13. The power interface terminal 15 is located on both sides of the housing 16.

[0043] Within the control and operation module 1, the handle 11 is connected to the drive shaft 14 via a connecting rod 13. When the operator operates the handle 11, its movement is transmitted to the drive shaft 14 through the connecting rod 13, thus converting and transmitting mechanical power. Power interface terminals 15 are located on both sides of the housing 16 for connecting external power lines to provide power to the entire control and operation module 1. The housing 16 adopts a base and cover structure to protect the internal components. This design ensures that the force from the operating handle 11 is transmitted to the drive shaft 14 efficiently and stably, guaranteeing operational reliability. The layout of the power interface terminals 15 facilitates wiring operations, and the housing 16's protection of the internal components effectively prevents the influence of external factors such as dust and moisture, extending the equipment's service life and improving operational stability.

[0044] Specifically, such as Figure 1 , Figure 2The upper end of the handle 11 passes through the power indicator driver 12. The left and right swing of the handle 11 can drive the power indicator driver 12 to move left and right. Power indicator relays 121 are installed at both ends of the control and operation module 1 near the power indicator driver 12. The left and right movement of the power indicator driver 12 drives the power indicator relays 121 at both ends to open and close, realizing the indication of power on and off.

[0045] The upper end of the handle 11 passes through the power indicator driver 12. When the handle 11 swings left and right, it drives the power indicator driver 12 to move synchronously left and right. Power indicator relays 121 are installed at both ends of the control and operation module 1 near the power indicator driver 12. The movement of the power indicator driver 12 can trigger the opening and closing of the power indicator relays 121 at both ends. The opening and closing states of the power indicator relays 121 correspond to different power on / off conditions, thereby realizing the indication of the power on / off state. Through intuitive power indicators, operators can quickly understand the power on / off state without the need for additional detection equipment, greatly improving the convenience of equipment operation and maintenance. At the same time, this visual indicator design reduces the possibility of operational errors and improves the safety of equipment operation.

[0046] Furthermore, such as Figure 1 , Figure 3 , Figure 6 As shown, contact module 2 includes a dual power supply conversion module, which comprises a contact system 21, an arc extinguishing system 22, a wiring system 23, and a magnetic drive system 24. The magnetic drive system 24 includes a push rod 241, a moving iron core 242, a winding 243, and a magnetic yoke 244. The magnetic drive system 24 is connected to the contact system 21 via the push rod 241 to drive the contact system 21 to switch. The arc extinguishing system 22 is located above the contact system 21 and is used to extinguish the arc generated during the switching process. The arc extinguishing system 23 is a conventional arc extinguishing structure in existing switches and will not be described in detail here.

[0047] The dual-power conversion module in contact module 2 integrates contact system 21, arc-extinguishing system 22, wiring system 23, and magnetic drive system 24. Magnetic drive system 24 is connected to contact system 21 via push rod 241. When the winding 243 of magnetic drive system 24 is energized, a magnetic field is generated, attracting the moving iron core 242. The moving iron core 242 drives push rod 241 to switch contact system 21, achieving dual-power conversion. Arc-extinguishing system 22 is located above contact system 21. When an arc is generated during the switching process of contact system 21, arc-extinguishing system 22 quickly extinguishes the arc using physical or chemical means, preventing damage to contacts and equipment. The integrated dual-power conversion module design combines multiple key functional systems, effectively reducing product size and saving space. Magnetic drive system 24 precisely drives contact system 21 to switch, ensuring the speed and stability of dual-power conversion. Arc-extinguishing system 22 promptly extinguishes the arc, protecting contacts and equipment, and improving equipment reliability and service life.

[0048] Furthermore, such as Figure 1 , Figure 4 As shown, the contact system 21 includes a moving contact 211, a transmission shaft 212, a stationary contact 213, a drive rod 214, a positioning conductive plate 215, a positioning shaft 216, a contact pressure retaining member 217, and a contact final pressure guaranteeing member 218. The moving contact 211 is connected to the transmission shaft 212. The positioning conductive plate 215 is fixed by the positioning shaft 216. The positioning conductive plate 215 consists of multiple parallel conductive plates. The moving contact 211 is located between the positioning conductive plates 215 and is pressed and positioned by the contact pressure retaining member 217. The contact final pressure guaranteeing member 218 is disposed between the moving contact 211 and the inner side of the transmission shaft 212. One end of the drive rod 214 is connected to the moving contact 211, and the other end is connected to the push rod 241 of the magnetic drive system 24.

[0049] In the contact system 21, the moving contact 211 is connected to the transmission shaft 212, and the positioning conductive plates 215 are fixed by the positioning shaft 216. Multiple parallel positioning conductive plates 215 form a fixed structure. The moving contact 211 is located between the positioning conductive plates 215. The contact pressure holding member 217 applies pressure to the moving contact 211, pressing it between the positioning conductive plates 215 to ensure good electrical contact. The contact final pressure guarantee member 218 is located between the moving contact 211 and the inner side of the transmission shaft 212. When the moving contact 211 and the stationary contact 213 are closed, it provides sufficient pressure to ensure the stability of the contact. One end of the drive rod 214 is connected to the moving contact 211, and the other end is connected to the push rod 241 of the magnetic drive system 24, transmitting the power of the magnetic drive system 24 to the moving contact 211 to realize the contact switching action. The spring structure of the contact pressure retainer 217 and the contact final pressure guarantee 218 can continuously and stably maintain the contact pressure between the moving contact 211 and related components, effectively avoiding problems such as poor contact and loosening, reducing the possibility of arcing, and improving the conductivity and dynamic and thermal stability of the contacts. The precise structural design of the contact system 21 ensures the accuracy and reliability of the contact switching action.

[0050] Furthermore, such as Figure 5 As shown, the contact pressure holding member 217 is a spring structure used to maintain the contact pressure between the moving contact 211 and the positioning conductive plate 215, and the contact final pressure guarantee member 218 is a spring structure used to ensure the pressure is maintained when the moving contact 211 and the stationary contact 213 are closed.

[0051] Both the contact pressure retainer 217 and the contact final pressure guarantee 218 employ spring structures, utilizing the elastic deformation of the spring to generate pressure. Under normal conditions, the contact pressure retainer 217, through its own elasticity, presses the moving contact 211 between the moving contact 211 and the positioning conductive plate 215, ensuring a stable contact pressure between the moving contact 211 and the positioning conductive plate 215. During the closing process between the moving contact 211 and the stationary contact 213, the contact final pressure guarantee 218 compresses the spring as the moving contact 211 moves, generating gradually increasing pressure to ensure that the required contact pressure is reached when the moving contact 211 and the stationary contact 213 are closed. The spring structure is simple, reliable, and low-cost, and the pressure can be flexibly adjusted according to actual needs. In this way, the contact pressure between the contacts is stably maintained, effectively reducing contact resistance, minimizing heat generation, extending the contact lifespan, and improving the overall performance and reliability of the dual power supply transfer switch.

[0052] Furthermore, such as Figure 4 , Figure 6As shown, there are at least three wiring systems 23, and each wiring system 23 includes a load terminal 231. The magnetic yoke 244 of the magnetic drive system 24 is a shared structure of two magnetic systems arranged in series. The two magnetic systems share the moving iron core 242 and the push rod 241.

[0053] There are at least three wiring systems 23, each including a load terminal 231 for connecting the load line. The magnetic drive system 24's yoke 244 employs a shared structure of two magnetic systems arranged in series, sharing a moving iron core 242 and a push rod 241. When the winding 243 of one magnetic system is energized, a magnetic field is generated, attracting the shared moving iron core 242. The moving iron core 242 drives the push rod 241, achieving the switching of the contact system 21. The other magnetic system is energized when reverse switching is required. The shared yoke 244, moving iron core 242, and push rod 241 design reduces the number of components in the magnetic system, simplifies the structure, and reduces the size of the magnetic drive system 24. Compared to traditional independent magnetic systems, it saves space, reduces production costs, and improves the integration and compactness of the magnetic drive system 24, making the overall structure of the dual-power transfer switch more rational and efficient.

[0054] Furthermore, such as Figure 6 As shown, the magnetic drive system 24 is a compact bidirectional drive magnetic system. By energizing different windings 243, the push rod 241 can move left and right. When the moving iron core 242 is on the right, the left winding 243 is energized and the moving iron core 242 moves to the left; conversely, when the moving iron core 242 is on the left, the right winding 243 is energized and the moving iron core 242 moves to the right.

[0055] The magnetic drive system 24 is a compact, bidirectional drive magnetic system that achieves the left and right movement of the push rod 241 by energizing different windings 243. When the moving iron core 242 is on the right, energizing the left winding 243 generates a magnetic field that attracts the moving iron core 242 to the left, driving the push rod 241 to the left and achieving the corresponding switching of the contact system 21. Conversely, when the moving iron core 242 is on the left, energizing the right winding 243 generates a magnetic field that attracts the moving iron core 242 to the right, driving the push rod 241 to the right and completing the reverse switching of the contact system 21. This bidirectional drive design allows the magnetic drive system 24 to precisely and flexibly control the movement direction of the push rod 241, achieving bidirectional switching of the contact system 21 and improving the switching efficiency and response speed of the dual power supply transfer switch. At the same time, the compact design further reduces the size of the magnetic drive system 24, lowers energy consumption, and improves energy utilization efficiency, giving the product significant advantages in both performance and energy saving.

[0056] Furthermore, such as Figure 2 , Figure 4As shown, one end of the transmission connecting member 3 is connected to the transmission shaft 14 of the control and operation module 1, and the other end is connected to the transmission rotating shaft 212 of the contact module 2, for transmitting the operation power of the control and operation module 1 to the contact module 2. The adjacent contact modules 2 are mutually driven and connected through the transmission rotating shaft 212.

[0057] One end of the transmission connecting member 3 is connected to the transmission shaft 14 of the control and operation module 1, and the other end is connected to the transmission rotating shaft 212 of the contact module 2, transmitting the operation power of the control and operation module 1 from the transmission shaft 14 to the transmission rotating shaft 212 of the contact module 2, thereby driving the contact system 21 to act. The adjacent contact modules 2 are mutually driven and connected through the transmission rotating shaft 212. When one contact module 2 acts, it drives the adjacent contact module 2 to act synchronously through the transmission rotating shaft 212, realizing the collaborative work of multiple contact modules 2. The transmission connecting member 3 ensures the effective transmission of the operation power, ensuring that the control and operation module 1 can accurately control the action of the contact module 2. The transmission connection mode of the adjacent contact modules 2 realizes the linkage operation of multiple contact modules 2, simplifies the operation process, and improves the operation efficiency. At the same time, this design makes the structure of the entire dual-power transfer switch more compact, the cooperation between modules is closer, and the overall performance and stability of the product are improved.

[0058] Furthermore, as Figure 1 shown, control interface terminals 5 are installed on both sides of the top of the control and operation module 1.

[0059] Control interface terminals 5 are installed on both sides of the top of the control and operation module 1 for connecting external control devices or signal sources. The external control signal is transmitted to the inside of the control and operation module 1 through the control interface terminals 5, realizing the remote control, automatic control of the dual-power transfer switch or the linkage control with other devices. The setting of the control interface terminals 5 provides rich control methods for the dual-power transfer switch, facilitating remote operation and automatic control, and meeting the needs of intelligent management of modern power systems. By connecting with other devices to achieve linkage control, the compatibility and coordination of the dual-power transfer switch with the entire power system are enhanced, and the intelligent level and reliability of the power system operation are improved.

[0060] When the dual-power transfer switch with the integrated layout module of the contact system and the magnetic system of the present utility model is in use, first, when the dual-power transfer switch needs to be operated, the operator can initiate an action instruction by operating the handle 11 in the control and operation module 1. The handle 11 is transmission-connected to the transmission shaft 14 through the connecting rod 13. When the handle 11 swings left and right, its movement is transmitted to the transmission shaft 14 through the connecting rod 13, converting the manual operation of the operator into mechanical power and realizing the preliminary transmission of power.

[0061] As the handle 11 moves, since the upper end of the handle 11 passes through the power indicator driver 12, the swing of the handle 11 will drive the power indicator driver 12 to move synchronously left and right. Power indicator relays 121 are installed at both ends of the control and operation module 1 near the power indicator driver 12. The movement of the power indicator driver 12 triggers the opening and closing of the power indicator relays 121 at both ends. The opening and closing states of the power indicator relays 121 correspond to different power on / off conditions, thus intuitively displaying the power on / off status to the operator, facilitating the operator's understanding of the equipment's operating status.

[0062] The drive shaft 14 of the control and operation module 1 is connected to the drive shaft 212 of the contact module 2 via the drive connector 3. The drive shaft 14 transmits power to the drive shaft 212, thereby driving the contact module 2 to operate. The dual power supply conversion module in the contact module 2 includes a contact system 21, an arc extinguishing system 22, a wiring system 23, and a magnetic drive system 24. The magnetic drive system 24, as the core drive component, uses a yoke 244 with two magnetic systems arranged in series, sharing a common structure, a moving iron core 242, and a push rod 241. When power switching is required, the corresponding winding 243 is energized according to the position of the moving iron core 242. For example, when the moving iron core 242 is on the right, energizing the left winding 243 causes the left winding 243 to generate a magnetic field that attracts the moving iron core 242 to move to the left, which in turn drives the push rod 241 to push to the left. Conversely, when the moving iron core 242 is on the left, energizing the right winding 243 causes the right winding 243 to generate a magnetic field that attracts the moving iron core 242 to move to the right, which in turn pushes the push rod 241 to the right. The movement of the push rod 241 is transmitted to the moving contact 211 of the contact system 21 via the drive rod 214, thus switching the contact system 21.

[0063] In the contact system 21, the moving contact 211 is connected to the transmission shaft 212. During the switching process, the contact pressure holding member 217 spring structure always maintains the contact pressure between the moving contact 211 and the positioning conductive plate 215 to ensure good electrical contact. When the moving contact 211 and the stationary contact 213 are closed, the contact final pressure guarantee member 218 spring structure provides sufficient pressure to ensure the stability of the contact and prevent problems such as poor contact.

[0064] During the switching process of the contact system 21, an electric arc will inevitably be generated. At this time, the arc extinguishing system 22 located above the contact system 21 will play a role in quickly extinguishing the arc through physical or chemical means, protecting the contacts and equipment, avoiding damage to the equipment by the arc, and ensuring the reliable operation of the dual power supply transfer switch.

[0065] Furthermore, the control interface terminals 5 on both sides of the top of the control and operation module 1 can be connected to external control devices or signal sources. When an external control signal is received, the signal is transmitted to the control and operation module 1 through the control interface terminals 5, enabling remote control, automated control, or linkage control with other devices of the dual power transfer switch, allowing the dual power transfer switch to better adapt to different power system needs and application scenarios. There are at least three wiring systems 23. The load terminal 231 of each wiring system 23 is used to connect to the load line, while the power interface terminals 15 are located on both sides of the housing 16 of the control and operation module 1 for connecting to external power lines, ensuring stable power input and output for the entire dual power transfer switch.

[0066] Finally, it should be noted that the electronic components in the arc extinguishing system 22 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between the electrical components in the above working principle to complete the electrical connection. All of these are technologies known in the art.

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.
