Description

Technical Field

[0001] The utility model relates to the technical field of power systems and automatic control, in particular to a novel embedded independent controller. Background Art

[0002] Many industrial and commercial facilities require backup power systems to ensure the continuous operation of critical equipment and systems. When the primary power source fails or undergoes maintenance, the backup power source can immediately take over, preventing production losses or equipment damage caused by power outages. Therefore, dual power transfer switches are essential for ensuring power supply reliability.

[0003] Traditional dual power transfer switch controllers are typically built into the switch itself, lacking a separate housing. This makes them unusable independently and incompatible with other models. With technological advancements and evolving market demands, user requirements for dual power transfer switches are constantly increasing, particularly in terms of modular design, embedded structure, maintainability, and space efficiency.

[0004] In summary, while existing dual-power transfer switch controller technology has met the basic requirements of industrial applications to a certain extent, there is still room for improvement, particularly in areas such as modularity, embedded design, overall replaceability, upper and lower board structures, and space saving. Therefore, this application has developed a new controller that integrates these features, which is of great significance for improving the performance and maintainability of dual-power transfer switches and reducing overall operating costs.

In the drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of the present invention, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present invention, and should not be understood as limitations on the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 、 2 , 3, 4, and 5, a novel embedded independent controller provided by this embodiment of the utility model includes a controller lower shell 1, a transformer 2, a main board 3, an HMI board 4, an HMI board support 5, and a controller upper shell 6;

[0025] First screw fastening holes 101 are fixedly provided at the four corners of the interior of the controller lower shell 1, a cross rib 102 is fixedly provided on at least one first side wall of the interior of the controller lower shell 1, a rib plate 103 is fixedly provided on at least one second side wall of the interior of the controller lower shell 1, and a positioning pin 104 is also fixedly provided inside the controller lower shell 1;

[0026] The mainboard 3 is connected to the first screw fastening hole of the controller lower shell 1 by bolts, and the positioning pin realizes the positioning of the mainboard, and the cross ribs and ribs realize the support of the mainboard; the transformer 2 is installed between the controller lower shell 1 and the mainboard 3;

[0027] A pair of second screw fastening holes 601 are fixedly provided inside the controller upper shell 6. A plurality of support ribs 602 are fixedly installed inside the controller upper shell 6 above and below the pair of second screw fastening holes. An HMI connection port 603 is provided on the controller upper shell 6 below the pair of second screw fastening holes. Correspondingly, a pair of fixing screws 501 are installed on the HMI board support 5. The HMI board support 5 is fixed to the controller upper shell 6 by the pair of fixing screws and the pair of second screw fastening holes. The HMI board support 5 is fixed to the controller upper shell 6, and the HMI board 4 is located between the HMI board support 5 and the controller upper shell 6. The pair of fixing screws are located on both sides of the HMI board 4 to achieve positioning of the HMI board 4.

[0028] It should be noted that the HMI board support 5 is designed here to support and install the HMI board, which can avoid opening holes in the HMI board and can play an insulating role, making the design more reasonable.

[0029] In addition, if Figure 2 As shown, a slot 7 is provided on the side wall of the controller upper shell 6 , through which the wiring harness on the mainboard 3 can be operated.

[0030] Several mounting feet 8 are provided on the outer wall of the controller lower shell 1, and two positioning holes 9 are provided on the back of the controller lower shell. The mounting feet 8 enable the controller to be installed inside the transfer switch, and the positioning holes 9 facilitate the positioning of the controller during installation, thereby improving the IP protection level and dielectric performance of the controller.

[0031] For example, in this embodiment, when assembling the controller, first install the transformer 2 and the mainboard 3 on the lower shell 1 of the controller, and use wires to connect the transformer and the mainboard; install the HMI board and the HMI board support on the upper shell of the controller in sequence, wherein the HMI board support is used to support the HMI board; then install the upper shell assembly of the controller on the lower shell of the controller, and the wiring harness connecting the mainboard and the HMI board can be connected through Figure 2 The slot 7 shown is operated, and after connection, a plastic label is used to stick it, and finally the connecting screws between the upper and lower shells are tightened; the traditional connection method is usually to use a wiring harness to connect the main board and the HMI board, and then install the controller upper shell to the controller lower shell. This will cause the wiring harness to be too long, increase costs, and there is a risk of wire crimping; therefore, the structure of the present application makes the connection method simpler and easier to operate.

[0032] Finally, it should be pointed out that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit them.
