Description

Technical Field

[0001] This utility model relates to the field of dual power supply switching technology, specifically a dual power supply switching device. Background Technology

[0002] A dual-power switching device is an electrical device used to ensure continuous power supply. Its core function is to automatically or manually switch to a backup power source (such as a generator or battery) when the main power source (such as the municipal power grid) fails (power outage, abnormal voltage, etc.), preventing the load from stopping work due to power failure. It is widely used in scenarios with high requirements for power supply reliability, such as medical facilities, data centers, and industrial production.

[0003] Currently, to ensure the safety and stability of dual power supply switching, dual power supply switches are usually installed in cabinets or boxes. However, the space inside the box is limited, and during assembly, wiring, or later maintenance, operators need to reach inside the dual power supply switching box, which hinders operation and affects use. Therefore, we propose a dual power supply switching device. Utility Model Content

[0028] Example 1

[0029] Please see Figures 1-6 As shown, this utility model provides a technical solution: a dual-power switching power supply device, comprising:

[0030] Box 1, with a door 2 connected to the front of box 1 via a hinge;

[0031] The C-shaped base 4 has guide rail grooves 401 on its top and bottom. The left and right ends of the inner side of the C-shaped base 4 are slidably connected to movable seats 402. The top and bottom of the movable seats 402 are fixedly connected to guide columns 404. The inner side of the movable seats 402 is hinged to a connecting rod 403. The other end of the connecting rod 403 is hinged to a connecting seat 405.

[0032] Mounting base plate 3, with a dual power automatic transfer switch 301 at the upper front end of the mounting base plate 3 and a circuit breaker 302 at the lower front end of the mounting base plate 3.

[0033] There are two C-shaped seats 4, and the two C-shaped seats 4 are located at the upper and lower ends of the rear side of the inner cavity of the housing 1, respectively. The guide post 404 is adapted to the guide rail groove 401, and the guide post 404 slides on the inner side of the guide rail groove 401. One end of the connecting seat 405 is located on the inner side of the C-shaped seat 4. The mounting base plate 3 is fixedly connected to one side of the connecting seat 405 by bolts.

[0034] This technical solution: By setting up a dual-power automatic transfer switch 301 and a circuit breaker 302, it can achieve the capability of automatic switching between dual power supplies (the mounting base 3 is also equipped with a neutral busbar and a ground busbar to ensure safe use, such as...). Figure 1 (As shown, this is existing technology, so it will not be described in detail again.) When assembly, wiring, or later maintenance is required, the box door 2 is opened. Then, the mounting base plate 3 can be moved outward from the box 1. When the mounting base plate 3 moves outward, it will cause the rear end of the connecting seat 405 to exit the inner side of the U-shaped seat 4, and can also cause the connecting rod 403 to move from horizontal to vertical. When the connecting rod 403 moves, under the cooperation of the guide rail groove 401 and the guide column 404, the moving seat 402 can move from the middle end of the U-shaped seat 4 to both ends. The movement of the mounting base 3 allows it to support the outward movement of the mounting base 3 (at this time, the mounting base 3 will move outside the housing 1, and the hinge between the connecting rod 403 and the moving seat 402 and the connecting seat 405 will not affect the operator's operation on the front of the mounting base 3). Moving the mounting base 3 outside the housing 1 facilitates the operator's operation and avoids the inconvenience caused by the small space. After the operation is completed, the mounting base 3 can be reset by the cooperation of the connecting rod 403, the moving seat 402 and the connecting seat 405. The operation is simple.

[0035] It should be noted that: at the power input end, the main and backup power supplies are independently connected, usually two mains power sources (such as from different busbars in the substation) or one mains power supply combined with one generator. The power supply and the incoming circuit breaker are directly connected in series to ensure that the power supply can be disconnected for maintenance when connected. Circuit breaker 302 acts as an intermediary. The incoming circuit breakers (one set for main and one set for backup) are connected in series between the power supply and the transfer switch to isolate the power supply (disconnected during maintenance) and provide short-circuit and overload protection. The load-side circuit breaker is connected in series between the dual power automatic transfer switch 301 and the load to protect downstream electrical equipment and prevent the load from being affected when a switching failure occurs. The dual power automatic transfer switch 301 has its input terminals connected to the incoming circuit breakers of the main and backup power supplies respectively, and its output terminal connected to the load-side circuit breaker, forming a "dual-input, single-output" switching logic. In addition, the existing model is selected according to the actual situation, and the circuit has not been modified.

[0036] Example 2

[0037] Based on Embodiment 1, this utility model is as follows: Figures 1-6 As shown, mounting pads 101 are provided on both the left and right ends of the rear side of the box 1, and a lock body 201 is fixedly installed on one end of the box door 2.

[0038] This technical solution facilitates the installation of the box body 1 by using the mounting pad 101, and enables the locking of the box door 2 between the box body 1 and the box door 2 by using the lock body 201.

[0039] Example 3

[0040] Based on Embodiment 1, this utility model is as follows: Figures 1-6 As shown, the left and right ends of the rear side of the inner cavity of the housing 1 are fixedly connected with internal threaded sleeves 5, and the left and right ends of the mounting base plate 3 are threadedly connected with tightening bolts 501, and the rear end of the tightening bolts 501 is threadedly connected to the internal threaded sleeves 5.

[0041] This technical solution: By setting the internal threaded sleeve 5, after the mounting base plate 3 is moved and reset into the housing 1, the tightening bolt 501 is rotated and tightened so that the rear end of the tightening bolt 501 is threadedly connected to the internal threaded sleeve 5, which can limit the position of the mounting base plate 3, thus facilitating the normal operation of the device.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
