[0002] Electricity-consuming enterprises such as steel, petroleum, chemical, fiber, metallurgy, and semiconductor chip manufacturing have high requirements for power supply continuity due to their production nature and process needs. When the main power supply (grid) fails at the upper or local level, resulting in power failure of the switching power supply and equipment damage, the dual power supply disturbance-free fast switching device provides a guarantee for uninterrupted power supply. The device uses an electromagnetic repulsion fast circuit breaker and is based on the "power supply failure rapid judgment technology" as the control basis. It can quickly and automatically switch to the backup power supply, ensuring uninterrupted power supply and preventing auxiliary machine shutdown.

[0003] When the existing power switch is in use, a large amount of heat will be generated during use due to the dual power supply set up inside the distribution cabinet. When the temperature inside the distribution cabinet is high, it will have a certain impact on the overall use of the dual power supply and the power switch. In addition, the overall humidity of the guest air in some environments is high. When it enters the distribution cabinet, it may cause certain damage to the power switch, reducing the overall service life of the dual power supply and the power switch.

[0004] In view of the above-mentioned related technologies, the inventors believe that the dual power supply disturbance-free fast switching device has the defect of being affected by the ambient temperature and humidity during use. Therefore, a dual power supply disturbance-free fast switching device is proposed to solve the above problem. Utility Model Content

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The embodiment of the present application discloses a dual power supply non-disturbance fast switching device. Figure 1-4 A dual-power disturbance-free fast switching device includes a power distribution cabinet 1, a cabinet door 2 is hinged on the edge of the front face of the power distribution cabinet 1, a power supply body 3 is symmetrically installed on the top of one end of the inner wall of the power distribution cabinet 1, and a power switch 4 is arranged on the inner wall of the power distribution cabinet 1 below the power supply body 3. When a fault occurs in the main power supply body 3 line, the power switch 4 switches the load to the backup power supply body 3 in the shortest possible time. After successful switching, the bus is powered by the backup power supply body 3. Once the fault of the main power supply body 3 is eliminated, the fast switching can be manually started to switch the load back to the main power supply body 3 to restore the normal power supply state. The fast switching controller is designed in a completely symmetrical manner, so the power switch 4 can be started from any power supply body 3, regardless of which line is the main power supply body 3 or the backup power supply body 3;

[0021] Ventilation holes 5 are provided on the top of both sides of the inner wall of the distribution cabinet 1, and an air inlet inner groove 6 is provided at the bottom of the distribution cabinet 1. Fixed air ducts 7 are fixedly installed on both sides of the inner wall of the air inlet inner groove 6, and a mounting bracket 8 is installed at the opening on one side of the fixed air duct 7. A placement groove 9 is provided on the upper surface of the mounting bracket 8, and an activated carbon plate 10 is installed inside the placement groove 9. A windshield bracket 13 is welded to the middle of the bottom end of the inner wall of the air inlet inner groove 6, and the cross-section of the windshield bracket 13 is a herringbone structure. A fixing component is also provided on one side of the mounting bracket 8 for installing the mounting bracket 8 inside the fixed air duct 7.

[0022] The two power supply bodies 3 are switched by controlling the power switch 4, so that the hot air in the distribution cabinet 1 is discharged outward through the vent 5, the activated carbon plate 10 is placed in the mounting bracket 8, and the mounting bracket 8 is installed inside the fixed air duct 7, so that the activated carbon plate 10 dehumidifies the fresh air blown in from the fixed air duct 7, keeping the distribution cabinet 1 in a dry state, reflecting the drying and dehumidification effect of the fresh air entering the distribution cabinet 1 from the fixed air duct 7.

[0023] Reference Figure 3 and Figure 4 The fixing component includes a limit plate 14, which is fixedly installed on one side of the mounting frame 8. A threaded groove 15 is provided on one side of the fixed air duct 7 near the four corners of the opening. One side of the limit plate 14 is placed in the threaded groove 15 and is threadedly connected to a limit bolt 16. Through holes are provided on one side of the limit plate 14 near the four corners. The threaded groove 15 and the through holes are aligned with each other, and one side of the outer surface of the limit bolt 16 is located inside the through hole.

[0024] By installing the mounting bracket 8 inside the fixed air duct 7, aligning the position of the limit plate 14 and the thread groove 15, rotating the limit bolt 16 through the limit plate 14 and threading it into the thread groove 15, and then fixing the limit plate 14 and the mounting bracket 8 at the opening position on one side of the fixed air duct 7, the overall disassembly and assembly fixing effect of the mounting bracket 8 is reflected.

[0025] Reference Figure 1 and Figure 3 A fixing bracket 11 is fixedly installed on the outer surface of the distribution cabinet 1 near the opening on the other side of the fixed air duct 7, and an intake fan 12 is rotatably installed at the middle position inside the fixing bracket 11. By starting the driving motor to drive the intake fan 12 to rotate, the intake fan 12 blows the fresh air outside the distribution cabinet 1 into the distribution cabinet 1, reflecting the overall air intake effect inside the distribution cabinet 1.

[0026] The implementation principle of a dual power supply disturbance-free fast switching device in the embodiment of the present application is as follows: by installing the power supply body 3 and the power switch 4 inside the distribution cabinet 1, the power supply body 3 and the power switch 4 are connected by a pipeline, so that the power switch 4 controls the two power supply bodies 3 to switch, and at the same time starts the air intake fan 12 to blow the external fresh air into the distribution cabinet 1 through the fixed air duct 7 for heat dissipation. A driving motor is provided on one side of the air intake fan 12, and the input end of the driving motor power supply is electrically connected to the output end of the external power supply, and the hot air in the distribution cabinet 1 is discharged outward through the vent 5. The activated carbon plate 10 is placed in the mounting bracket 8, and the mounting bracket 8 is installed inside the fixed air duct 7, so that the activated carbon plate 10 can blow the fresh air blown into the fixed air duct 7. Fresh air is dehumidified to keep the distribution cabinet 1 in a dry state. By rotating multiple limit bolts 16 and placing them in the threaded groove 15, the limit bolts 16 fix the limit plate 14 on the outer surface of the fixed air duct 7, and then fix the mounting bracket 8 on the fixed air duct 7. Rotating the limit bolts 16 controls the limit of the mounting bracket 8, which helps to disassemble and replace the activated carbon plate 10. Compared with the existing technology, this solution has the effect of facilitating heat dissipation and dehumidification of the internal environment of the distribution cabinet 1, improving the overall protection effect of the power supply main body 3 and the power switch 4, solving the problem of damage to the power supply main body 3 and the power switch 4 caused by high temperature and humidity, and improving the overall utilization efficiency of the power supply main body 3 and the power switch 4.
