Description

Technical Field

[0001] The present invention relates to the technical field of equipment cabinets, and in particular to an equipment cabinet capable of switching power supply lines. Background Art

[0002] With the development of science and technology, there are many different ways to generate electricity, and different places also use different power supply lines. Generally, users in a place only use one set of power supply lines. However, when this set of power supply lines is accidentally cut off, this set of lines can no longer supply power, resulting in a lack of electricity in the area. Therefore, some important areas will set up another set of power supply lines to supply power through two sets of power supply lines. The two sets of power supply lines are not used at the same time. When one set of power supply lines does not provide power, the line is switched to the other set of power supply lines to ensure that the area is fully powered. In the existing technology, switches are set on both sets of power supply lines, and the two switches work independently. At the same time, multiple sets of output lines are also set up. This results in multiple sets of output lines being connected to both switches. This not only makes line connection troublesome, but also easily leads to safety accidents due to the large number of lines. Summary of the Invention

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0029] See Figures 1-8 , the present invention provides a technical solution:

[0030] A device cabinet for switchable power supply lines includes a cabinet 1, a first input circuit breaker 2, a second input circuit breaker 3, a circuit switcher 4, an output circuit breaker 5, a surge protector 6, and a leakage circuit breaker 7. The circuit switcher 4 is fixedly mounted within the cabinet 1 and is provided with a first input terminal 8, a second input terminal 9, and an output terminal 10. The output circuit breaker 5, the surge protector 6, and the leakage circuit breaker 7 are all fixedly mounted within the cabinet 1 and electrically connected to the output terminal 10. The first input circuit breaker 2 is fixedly mounted within the cabinet 1 and electrically connected to the first input terminal 8. The second input circuit breaker 3 is fixedly mounted within the cabinet 1 and electrically connected to the second input terminal 9. An electric meter 40 is provided on the output circuit of the leakage circuit breaker 7. A current transformer 41 is provided on the output circuit of the output circuit breaker 5. Among them, a cabinet door is provided on the cabinet body 1, which is generally opened when the circuit is being maintained, and is closed in other cases. The function of the cabinet body 1 is to install the first input circuit breaker 2, the second input circuit breaker 3, the circuit switcher 4, the output circuit breaker 5, the surge protector 6 and the leakage circuit breaker 7. The circuit switcher 4 is arranged in the middle part of the cabinet body 1, and the first input circuit breaker 2 and the second input circuit breaker 3 are arranged side by side on the upper side of the circuit switcher 4. The input end of the first input circuit breaker 2 is electrically connected to a group of input cables, and the output end of the first input circuit breaker 2 is electrically connected to the first input terminal 8 on the circuit switcher 4 through a cable. The input end of the second input circuit breaker 3 is electrically connected to another group of input cables, and the output end of the second input circuit breaker 3 is electrically connected to the second input terminal 9 on the circuit switcher 4 through a cable. A set of output terminals 10 is provided on the circuit switcher 4. The input terminals of the output circuit breaker 5 and the leakage circuit breaker 7 are both connected to the output terminals 10. Each of the output circuit breaker 5 and the leakage circuit breaker 7 can be provided with one or more. The number of output circuit breakers 5 and leakage circuit breakers 7 provided is determined based on demand. In the prior art, three-phase power is often used for transmission. Therefore, the first input circuit breaker 2, the second input circuit breaker 3, the output circuit breaker 5, and the leakage circuit breaker 7 are all circuit breakers for three sets of transmission lines in the prior art. The circuit switcher 4 is provided with three first input terminals 8, three second input terminals 9, and three output terminals 10. The surge protector 6 is an overvoltage protector known in the prior art. The surge protector 6 is electrically connected to the output terminal 10 to limit the output voltage and prevent damage to user-end equipment. The watt-hour meter 40 and the current transformer 41 are both existing technology devices. Each output line of the leakage circuit breaker 7 is provided with a watt-hour meter 40 for recording the electric energy used on the output line. The current transformer 41 is used to output the current output from the circuit breaker 5.Before the circuit switch 4 is set up, assuming that there are six groups of output lines using electricity, then six groups of output lines need to be connected to the output end of the first input circuit breaker 2, and six groups of output lines need to be connected to the output end of the second input circuit breaker 3. Therefore, twelve groups of output lines need to be set up. If the twelve groups of output lines are all equipped with electricity meters 40, twelve electricity meters 40 are also required. After the circuit switch 4 is set up, only six groups of output lines need to be connected to the output terminal 10. This not only saves a lot of line installation, but also reduces the occurrence of safety accidents due to the reduction in the number of output lines. At the same time, it is also convenient for maintenance when problems arise.

[0031] In some embodiments, the circuit switcher 4 includes an insulating box 11, an insulating seat 12, a conductive rod 13, a first plug 14, a second plug 15, a first slot 16, a second slot 17, a connecting ring 18, and a driving component. The insulating box 11 is disposed within the cabinet 1, the insulating seat 12 is disposed within the insulating box 11, the conductive rod 13 is rotatably disposed within the insulating seat 12, the first slot 16 and the second slot 17 are respectively fixedly disposed at both ends of the insulating seat 12, and the first slot 16 and the second slot 17 are respectively disposed on both sides of the conductive rod 13, the first plug 14 is fixedly disposed on the conductive rod 13 and cooperates with the first slot 16, the second plug 15 is fixedly disposed on the conductive rod 13 and cooperates with the second slot 17, the driving component is fixedly disposed within the insulating box 11 and is used to drive the conductive rod 13 to rotate, and the connecting ring 18 is fixedly disposed on the insulating seat 12 and electrically connected to the conductive rod 13. The insulating box 11 is used to mount the insulating seat 12, the driving component, the three first input terminals 8, the three second input terminals 9, and the three output terminals 10. The first input terminal 8, the second input terminal 9, and the output terminal 10 each include an outer insulator and an inner conductive core. The inner conductive core is fixedly mounted within the outer insulator, with both ends of the inner conductive core exposed outside the outer insulator. One end of the inner conductive core is a connector with a hole, and the other end is a plug connector. The plug connector ends of the first input terminal 8, the second input terminal 9, and the output terminal 10 are all mounted within the insulating box 11. The first slot 16 is provided with a first socket 42, into which the plug connector on the first input terminal 8 is inserted. The second slot 17 is provided with a second socket 43, into which the plug connector on the second input terminal 9 is inserted. The connecting ring 18 is provided with a third socket 44, into which the plug connector on the output terminal 10 is inserted. Conductive springs 45 are disposed within the first, second, and third sockets 42, 43, and 44, respectively, ensuring full contact between the plug connector and the conductive springs 45 for electrical conduction. The insulating box 11 includes a box body and a box cover. The box body and the box cover are detachably connected by bolts. The outer insulator on the output terminal 10 is fixedly connected to the bottom of the box body. The outer insulators of the first input terminal 8 and the second input terminal 9 are fixedly connected to the box cover. The insulating seat 12 is fixed to the bottom of the insulating box 11. When the insulating seat 12 is installed, the inner conductive core on the output terminal 10 is directly inserted into the third jack 44. The insulating seat 12 and the insulating box 11 are fixed by screws. Since three-phase power supply is adopted, three insulating seats 12 are provided in the insulating box 11. The driving component drives the conductive rods 13 on the three insulating seats 12 to rotate simultaneously. Among them, the function of the insulating seat 12 is to install the conductive rod 13, the first slot 16, the second slot 17 and the connecting ring 18. The conductive rod 13, the first slot 16, the second slot 17 and the connecting ring 18 are all made of conductive materials, such as copper, silver and alloys.The connecting ring 18 always maintains an electrical connection with the conductive rod 13. The first slot 16 and the second slot 17 are diagonally arranged on the insulating seat 12. The first plug 14 and the second plug 15 are both fixed on the conductive rod 13. When the first plug 14 is in contact with the first slot 16 for electrical conduction, the second plug 15 is in a completely separated state from the second slot 17. When the second plug 15 is in contact with the second slot 17 for electrical conduction, the first plug 14 is in a completely separated state from the first slot 16. In this technology, there is no situation where the first plug 14 is in contact with the first slot 16 while the second plug 15 is in contact with the second slot 17. The first slot 16 and the second slot 17 are both concave-shaped. Curved spring clips 46 are fixedly mounted on the inner walls of both sides of the first slot 16 and the second slot 17. The center of the curved spring clips 46 is on the axis of the conductive rod 13. The curved spring clips 46 are made of conductive metal and are electrically conductive. When the first insert 14 and the first slot 16 are in electrical contact, the two sides of the first insert 14 contact the curved spring clips 46 on either side of the first slot 16. When the second insert 15 and the second slot 17 are in electrical contact, the two sides of the second insert 15 contact the curved spring clips 46 on either side of the second slot 17. The ends of the first insert 14 and the second insert 15 are arc-shaped, and the edges of the first insert 14, the second insert 15, the first slot 16, the second slot 17, and the curved spring clips 46 are all rounded.

[0032] In some embodiments, the conductive rod 13, the first slot 16, and the second slot 17 are arranged on the same horizontal plane, and the angle θ between the first insert 14 and the second insert 15 is no greater than 90°. To reduce the impact of arcing, the conductive rod 13, the first slot 16, and the second slot 17 are arranged on the same horizontal plane, and the first slot 16 and the second slot 17 are arranged on either side of the conductive rod 13, thereby increasing the distance between the first slot 16 and the second slot 17 and preventing mutual interference between the first slot 16 and the second slot 17. The angle between the first insert 14 and the second insert 15 ranges from 50° to 80°. 50°, 60°, 70°, and 80° are commonly used.

[0033] In some embodiments, an insulating sliding cover 19 is provided on the insulating seat 12 to cooperate with the insulating seat 12. Guide grooves 20 are provided on both sides of the insulating seat 12. The two side edges of the insulating sliding cover 19 are respectively provided in the two guide grooves 20. A first cavity 21 that cooperates with the first plug 14 is provided in one end of the insulating sliding cover 19, and a second cavity 22 that cooperates with the second plug 15 is provided in the other end of the insulating sliding cover 19. A first arc-cutting plate 23 is fixedly provided in the first cavity 21, and a first through-slot 24 that cooperates with the first plug 14 is provided in the first arc-cutting plate 23. A second arc-cutting plate 25 is fixedly provided in the second cavity 22, and a second through-slot 26 that cooperates with the second plug 15 is provided in the second arc-cutting plate 25. The guide grooves 20 on both sides of the insulating seat 12 are provided between the first insertion hole 42 and the second insertion hole 43. During the sliding process of the insulating sliding cover 19, the insulating sliding cover 19 does not affect the first input terminal 8 and the second input terminal 9. During rotation, the conductive rod 13 drives the first and second inserts 14, 15 to rotate simultaneously. To prevent the insulating sliding cover 19 from obstructing the rotation of the first and second inserts 14, 15, a first cavity 21 and a second cavity 22 are provided. The first insert 14 rotates within the first cavity 21, and the second insert 15 rotates within the second cavity 22. Separation of the first insert 14 from the first slot 16 may generate an arc, and separation of the second insert 15 from the second slot 17 may also generate an arc. Therefore, a first arc-cutting plate 23 is provided in the first cavity 21, and a second arc-cutting plate 25 is provided in the second cavity 22. When the conductive rod 13 rotates and drives the first plug-in piece 14 to be inserted into the first slot 16, the conductive rod 13 simultaneously drives the insulating sliding cover 19 to move, and the first through slot 24 on the first arc-cutting plate 23 cooperates with the first slot 16. At the same time, the second plug-in piece 15 leaves the second slot 17, and the second arc-cutting plate 25 on the insulating sliding cover 19 covers the second slot 17, which can cut off the arc between the second plug-in piece 15 and the second slot 17; when the conductive rod 13 rotates and drives the second plug-in piece 15 to be inserted into the second slot 17, the conductive rod 13 simultaneously drives the insulating sliding cover 19 to move, and the second through slot 26 on the second arc-cutting plate 25 cooperates with the second slot 17. At the same time, the first plug-in piece 14 leaves the first slot 16, and the first arc-cutting plate 23 on the insulating sliding cover 19 covers the first slot 16, which can cut off the arc between the first plug-in piece 14 and the first slot 16. The plane where the first insert 14 is located is parallel to the plane where the second insert 15 is located, the plane where the first arc-cutting plate 23 is located is perpendicular to the plane where the first insert 14 is located, and the plane where the second arc-cutting plate 25 is located is perpendicular to the plane where the second insert 15 is located.

[0034] In some embodiments, a push plate 27 is fixedly mounted on the end of the insulating sliding cover 19. The push plate 27 is provided with a Z-shaped groove 28. A rigid roller 29 is disposed in the Z-shaped groove 28 and cooperates with the Z-shaped groove 28. The rigid roller 29 is rotatably mounted on a push rod 30, and the push rod 30 is fixedly connected to the conductive rod 13. The Z-shaped groove 28 includes a first transverse section, a second transverse section, and an inclined section. The inclined section is connected between the first and second transverse sections. The angle between the first and second transverse sections is 135° to 160°, and is typically set to 150°. A circular arc transition is used between the first transverse section and the inclined section, and a circular arc transition is used between the second transverse section and the inclined section. The Z-shaped groove 28 is Z-shaped when viewed from the front and is arc-shaped when viewed from above. The rigid roller 29 rotates on one end of the push rod 30, and the other end of the push rod 30 is fixedly connected to the conductive rod 13. When the conductive rod 13 rotates, the push rod 30 is driven to swing, and the push rod 30 drives the rigid roller 29 to work. The rigid roller 29 cooperates with the Z-shaped groove 28 to drive the insulating sliding cover 19 and the push plate 27 to slide on the insulating seat 12.

[0035] In some embodiments, the driving components include a driving motor 31, a driving rod 32, a driving wheel 33, an insulating end sleeve 34 and a connecting frame 35. The insulating end sleeve 34 is coaxially fixed on the end of the conductive rod 13, the driving wheel 33 is coaxially fixed on the insulating end sleeve 34, the connecting frame 35 is fixed on the end of the insulating seat 12, the driving rod 32 is rotatably set on the connecting frame 35 and is used to drive the driving wheel 33 to rotate, and the driving motor 31 is fixedly set on the insulating box 11 and the output end is transmission connected to the driving rod 32. Among them, a connecting frame 35 is fixedly provided on each insulating seat 12. In this technology, three insulating seats 12 are arranged in a row, and the three connecting frames 35 on the three insulating seats 12 are arranged in a row. The three connecting frames 35 are connected through the same driving rod 32. The driving rod 32 is a worm in the prior art, and the driving wheel 33 is a turbine that cooperates with the worm in the prior art. The conductive rod 13 and the driving wheel 33 are connected through an insulating end sleeve 34, which can effectively prevent the conductive rod 13 and the driving wheel 33 from conducting electricity. The driving motor 31 is a servo motor in the prior art, and the output shaft of the servo motor is connected to the end of the conductive rod 13 through the bevel gear set 47 in the prior art.

[0036] In some embodiments, a limiting groove 36 is provided on the insulating seat 12. An outer conductive ring 37 connected to the output terminal 10 is disposed within the limiting groove 36. An inner conductive ring 38 is coaxially disposed within the outer conductive ring 37. The inner conductive ring 38 is coaxially fixedly connected to the conductive rod 13. End bearings 39 are disposed on both sides of the inner conductive ring 38 between the inner wall of the limiting groove 36. The connecting ring 18 is fixedly connected to the outer conductive ring 37. The outer conductive ring 37 and the inner conductive ring 38 are coaxially disposed. The outer wall of the inner conductive ring 38 contacts the inner wall of the outer conductive ring 37. The inner conductive ring 38 is coaxially fixedly connected to the conductive rod 13. Since the conductive rod 13 pushes the insulating sliding cover 19 to move, the conductive rod 13 is subjected to axial force. Therefore, end bearings 39, as is conventional in the art, are disposed on both sides of the inner conductive ring 38. The two end bearings 39 are disposed within the limiting groove 36 and sleeved on the conductive rod 13, thereby limiting the axial movement of the conductive rod 13.
