Description

Technical Field

[0001] This utility model relates to the field of sensorless power conversion technology, and in particular to a sensorless power conversion controller. Background Technology

[0002] Seamless power transfer refers to a process where power supply switching or load transfer is achieved through technological means, making power outages or service interruptions virtually imperceptible to users. The seamless power transfer controller is the core device enabling this function. It accurately monitors the operating status of the power system, including key parameters such as voltage, current, and frequency. When a situation that may lead to a power outage or requires load transfer is detected, the seamless power transfer controller reacts quickly, automatically adjusting the power supply path according to pre-set programs and algorithms. It possesses intelligent judgment capabilities, selecting the optimal power transfer scheme based on different power demands and system conditions to ensure that the impact on users' electricity consumption is minimized during the transfer process.

[0003] Furthermore, the sensorless power transfer controller also possesses powerful communication and data processing capabilities. It can communicate in real time with other devices in the power system, such as substation monitoring systems and distributed power source controllers, to achieve information sharing and interaction. Existing sensorless power transfer controllers are usually installed in transfer cabinets. Due to processing power requirements, multiple controllers and sensors are typically needed. To balance installation space and heat dissipation requirements, various controllers and sensors are usually staggered, such as placed facing forward or to the side relative to the cabinet door. This makes it inconvenient to inspect controller modules in different positions, hindering centralized management and maintenance of individual controllers and sensors. When a specific device needs to be replaced or upgraded, it may be obstructed by surrounding devices, making maintenance operations difficult. Utility Model Content

[0018] Reference Figures 1 to 4This utility model provides a contactless electric controller, comprising: a support mechanism 1, a connecting mechanism 2, and a controller body 3. The support mechanism 1 includes a support plate 11, on which a first connecting slide bar 12 and a second connecting slide bar 14 are fixedly connected. A connector 13 is fixedly connected to the first connecting slide bar 12, and a mounting groove 15 is provided on the second connecting slide bar 14. A retractable docking piece 19 is provided in the mounting groove 15. An adjusting component for adjusting the retraction of the docking piece 19 is provided in the support plate 11. The connecting mechanism 2 includes a connecting block 21. The connecting block 21 has a snap-fit ​​groove 22 corresponding to the connecting member 13, and the connecting block 21 has a connecting groove 23. The snap-fit ​​groove 22 and the connecting groove 23 are connected. The mounting end face of the controller body 3 has a connecting slide groove one and a connecting slide groove two respectively. The connecting slide bar one 12 is slidably disposed in the connecting slide groove one. The connecting slide groove one has an embedding groove. The connecting mechanism 2 is fixedly connected in the embedding groove. The connecting slide bar two 14 is slidably disposed in the connecting slide groove two. The connecting slide groove two has a mating groove. The mating member 19 is snapped into the mating groove.

[0019] like Figure 1 As shown, a sensorless power converter also includes a mounting cabinet 100, which contains a mounting frame 101. Two controller bodies 3 are respectively positioned sideways or forward relative to the cabinet door via a support mechanism 1 and a connecting mechanism 2. This makes it inconvenient to inspect controller modules in different positions, hindering centralized management and maintenance of individual controllers and sensors. During installation, the second connecting slide bar 14 slides within the second connecting groove, which has a mating groove. A mating piece 19 engages with this groove. Simultaneously, the first connecting slide bar 12 slides within the first connecting groove, and a connecting piece 13 engages with the engaging groove 22 of the connecting mechanism 2, allowing the controller body 3 to... Securely mounted on the support mechanism 1, when maintenance of the controller body 3 is required, the support plate 11 is equipped with an adjustable assembly for the extension and retraction of the adjustable docking piece 19, and the snap-fit ​​groove 22 is connected to the connecting groove 23. By adjusting the assembly, the docking piece 19 can be pulled out, and the controller body 3 can be slid from the snap-fit ​​groove 22 side toward the connecting groove 23 side, so that the connecting piece 13 can be dislodged from the snap-fit ​​groove 22. The controller body 3 can then be lifted out toward the side away from the support mechanism 1, thus completing the disassembly of the controller body 3. The support mechanism 1 and the connecting mechanism 2 make it easy to disassemble the controller body 3 in different installation positions, facilitating centralized management and maintenance of various controllers and sensors, and providing good maintainability.

[0020] A connecting slot is provided through the support plate 11, which is connected to the mounting slot 15. The adjustment component includes a connecting rod 16 and a pull plate 17. The pull rod 16 is movably sleeved in the connecting slot and the mounting slot 15. One end of the pull rod 16 is fixedly connected to the pull plate 17, and the other end of the pull rod 16 is fixedly connected to the docking piece 19. A spring is sleeved on the pull rod 16 and is set in the mounting slot 15. One end of the spring is fixedly connected to the inner wall of the mounting slot 15, and the other end of the spring is fixedly connected to the docking piece 19. Under normal installation conditions, the spring is in a natural state or has a certain preload, so that the docking piece 19 is stably engaged in the docking slot, ensuring a firm connection between the controller body 3 and the support mechanism 1. When it is necessary to disassemble the controller body 3, the operator pulls the pull plate 17. The pull plate 17 drives the pull rod 16 to slide in the connecting groove and the mounting groove 15. Since the pull rod 16 is fixedly connected to the docking part 19, the docking part 19 will be pulled out of the docking groove as the pull rod 16 slides. At the same time, the spring is compressed. After the docking part 19 is completely pulled out of the docking groove, the controller body 3 can be slid from the snap-fit ​​groove 22 side to the connecting groove 23 side as described above, so that the connecting part 13 is disengaged from the snap-fit ​​groove 22. Then, the controller body 3 is lifted out to the side away from the support mechanism 1.

[0021] In some specific embodiments, a groove 18 is provided on the upper end face of the pull plate 17, which facilitates the pulling of the docking part 19 and improves the ease of use of the device.

[0022] Workflow: The mounting cabinet 100 contains a mounting frame 101. The two controller bodies 3 are positioned sideways or forward relative to the cabinet door via a support mechanism 1 and a connecting mechanism 2, respectively. This makes maintenance of controller modules in different locations inconvenient and hinders centralized management and maintenance of individual controllers and sensors. During installation, the second connecting slide bar 14 slides within the second connecting groove, which has a mating groove. The mating piece 19 engages with this groove. Simultaneously, the first connecting slide bar 12 slides within the first connecting groove, and the connecting piece 13 engages with the engaging groove 22 of the connecting mechanism 2. This allows the controller body 3 to be securely mounted on the support mechanism 1. When maintenance is required on the controller body 3, since the support plate 11 is equipped with an adjustable assembly for the extension and retraction of the adjustable docking piece 19, and the snap-fit ​​groove 22 is connected to the connecting groove 23, the docking piece 19 can be pulled out by adjusting the assembly. At this time, the controller body 3 can be slid from the snap-fit ​​groove 22 side toward the connecting groove 23 side, so that the connecting piece 13 can be disengaged from the snap-fit ​​groove 22. The controller body 3 can be lifted out toward the side away from the support mechanism 1, thus completing the disassembly of the controller body 3. The support mechanism 1 and the connecting mechanism 2 make it easy to disassemble the controller body 3 in different installation positions, which facilitates centralized management and maintenance of various controllers and sensors, and has good maintainability.
