Description

Technical Field

[0001] The present invention relates to the technical field of equipment cabinets, and particularly relates to an equipment cabinet with a switchable power supply line. Background Art

[0002] With the development of science and technology, there are various ways of power generation, and different power supply lines are adopted in different places. Generally, users in a place only use a group of power supply lines. However, when this group of power supply lines is accidentally powered off, this group of lines can no longer supply power, resulting in no electrical energy available in this place. Therefore, an additional group of power supply lines will be erected in some important areas, and power supply is carried out through two groups of power supply lines. The two groups of power supply lines are not used simultaneously. When one group of power supply lines does not supply power, the line is switched to the other group of power supply lines, so as to ensure sufficient power supply in this area. In the prior art, switches are provided on both groups of power supply lines, and the two switches work independently. At the same time, multiple groups of output lines are also provided on the output line, which leads to multiple groups of output lines being connected to both switches. This not only makes the line connection troublesome but also easily causes safety accidents due to the large number of lines. Summary of the Invention

Specific embodiments

[0018] Next, the technical solution of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0019] Refer to Figures 1-8 , the present invention provides a technical solution: An equipment cabinet with a switchable power supply line, comprising a cabinet body 1, a first input circuit breaker 2, a second input circuit breaker 3, a circuit switch 4, an output circuit breaker 5, a surge protector 6 and a leakage circuit breaker 7. The circuit switch 4 is fixedly arranged in the cabinet body 1. A first input terminal 8, a second input terminal 9 and an output terminal 10 are arranged on the circuit switch 4. The output circuit breaker 5, the surge protector 6 and the leakage circuit breaker 7 are all fixedly arranged in the cabinet body 1 and are all electrically connected to the output terminal 10. The first input circuit breaker 2 is fixedly arranged in the cabinet body 1 and is electrically connected to the first input terminal 8. The second input circuit breaker 3 is fixedly arranged in the cabinet body 1 and is electrically connected to the second input terminal 9. An electric energy meter 40 is arranged on the output circuit of the leakage circuit breaker 7. A current transformer 41 is arranged on the output circuit of the output circuit breaker 5. Among them, a cabinet door is arranged on the cabinet body 1, which is generally opened during circuit maintenance, and the cabinet door is in a closed state 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 switch 4, the output circuit breaker 5, the surge protector 6 and the leakage circuit breaker 7. The circuit switch 4 is arranged in the middle of the cabinet body 1. The first input circuit breaker 2 and the second input circuit breaker 3 are arranged in parallel on the upper side of the circuit switch 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 switch 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 switch 4 through a cable. A group of output terminals 10 are arranged on the circuit switch 4. The input ends of the output circuit breaker 5 and the leakage circuit breaker 7 are both connected to the output terminal 10. One output circuit breaker 5 and one leakage circuit breaker 7 can be arranged respectively, or multiple can be arranged. The number of the output circuit breaker 5 and the leakage circuit breaker 7 arranged is set according to requirements. In the prior art, three-phase electricity is often used for power 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 groups of power transmission lines in the prior art. Three first input terminals 8, three second input terminals 9 and three output terminals 10 are arranged on the circuit switch 4. The surge protector 6 is an overvoltage protector in the prior art. The surge protector 6 is electrically connected to the output terminal 10 to limit the output voltage and prevent the equipment at the user end from being damaged. The electric energy meter 40 and the current transformer 41 are both equipment in the prior art. An electric energy meter 40 is arranged on the output line of each leakage circuit breaker 7 to record the electric energy used on this output line. The current transformer 41 is used to measure the current output by the output circuit breaker 5.Before the circuit switch 4 is set, assuming that six sets of output lines are in use, six sets of output lines need to be connected to the output terminal of the first input circuit breaker 2, and six sets of output lines also need to be connected to the output terminal of the second input circuit breaker 3. Therefore, twelve sets of output lines need to be set. If electric energy meters 40 are set for all twelve sets of output lines, twelve electric energy meters 40 are also required. After the circuit switch 4 is installed, only six sets of output lines need to be connected to the output terminal 10. This not only saves a large amount of line erection 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 after problems occur.

[0020] In some embodiments, the circuit switch 4 includes an insulating box 11, an insulating seat 12, a conductive rod 13, a first insert piece 14, a second insert piece 15, a first slot 16, a second slot 17, a connection ring 18, and a driving component. The insulating box 11 is disposed in the cabinet 1, the insulating seat 12 is disposed in the insulating box 11, the conductive rod 13 is rotatably disposed in 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 insert piece 14 is fixedly disposed on the conductive rod 13 and cooperates with the first slot 16, and the second insert piece 15 is fixedly disposed on the conductive rod 13 and cooperates with the second slot 17. The driving component is fixedly disposed in the insulating box 11 and is used to drive the conductive rod 13 to rotate. The connection ring 18 is fixedly disposed on the insulating seat 12 and is electrically connected to the conductive rod 13. Among them, the insulating box 11 is used to install the insulating seat 12, the driving component, three first input terminals 8, three second input terminals 9, and 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 disposed within the outer insulator, and both ends of the inner conductive core protrude outside the outer insulator. One end of the inner conductive core is a perforated connector, 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 disposed inside the insulating box 11. A first jack 42 is provided on the first slot 16, and the plug connector on the first input terminal 8 is inserted into the first jack 42. A second jack 43 is provided on the second slot 17, and the plug connector on the second input terminal 9 is inserted into the second jack 43. A third jack 44 is provided on the connection ring 18, and the plug connector on the output terminal 10 is inserted into the third jack 44. Conductive elastic pieces 45 are provided in the first jack 42, the second jack 43, and the third jack 44, and full contact is made between the plug connector and the conductive elastic piece 45 for conducting electricity. The insulating box 11 includes a box body and a box cover, and 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, and 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 on the bottom of the insulating box 11. When installing the insulating seat 12, the inner conductive core on the output terminal 10 is directly inserted into the third jack 44, and 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, and 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 connection ring 18. The conductive rod 13, the first slot 16, the second slot 17, and the connection ring 18 are all made of conductive materials, such as copper, silver, and alloys, etc.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 base 12. The first insert 14 and the second insert 15 are both fixed on the conductive rod 13. When the first insert 14 contacts and conducts electricity with the first slot 16, the second insert 15 is in a completely separated state from the second slot 17. When the second insert 15 contacts and conducts electricity with the second slot 17, the first insert 14 is in a completely separated state from the first slot 16. In this technology, there is no situation where the first insert 14 contacts the first slot 16 while the second insert 15 contacts the second slot 17 at the same time. Both the first slot 16 and the second slot 17 are arranged in a concave shape. Arc-shaped elastic pieces 46 are fixedly arranged on the inner walls on both sides of the first slot 16 and the second slot 17. The centers of the arc-shaped elastic pieces 46 are on the axis of the conductive rod 13. The arc-shaped elastic pieces 46 are made of conductive metal and can conduct electricity. When the first insert 14 cooperates with the first slot 16 to conduct electricity, both sides of the first insert 14 contact the arc-shaped elastic pieces 46 on both sides of the first slot 16. When the second insert 15 cooperates with the second slot 17 to conduct electricity, both sides of the second insert 15 contact the arc-shaped elastic pieces 46 on both sides of the second slot 17. The ends of the first insert 14 and the second insert 15 are arc-shaped. The edges of the first insert 14, the second insert 15, the first slot 16, the second slot 17, and the arc-shaped elastic piece 46 are all rounded off.

[0021] In some embodiments, the conductive rod 13, the first slot 16, and the second slot 17 are arranged on the same horizontal plane. The included angle between the first insert 14 and the second insert 15 is θ, and the included angle θ is not greater than 90°. Among them, in order to reduce the influence of the arc, 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 respectively arranged on both sides of the conductive rod 13, so that the distance between the first slot 16 and the second slot 17 is farther, preventing mutual influence between the first slot 16 and the second slot 17. The angular range between the first insert 14 and the second insert 15 is from 50° to 80°. Generally, 50°, 60°, 70°, and 80° are often selected.

[0022] In some embodiments, an insulating sliding cover 19 that mates with the insulating base 12 is provided on the insulating base 12. Guide grooves 20 are provided on both sides of the insulating base 12, and both sides of the insulating sliding cover 19 are respectively disposed in the two guide grooves 20. A first cavity 21 that mates with the first insert 14 is provided inside one end of the insulating sliding cover 19, and a second cavity 22 that mates with the second insert 15 is provided inside the other end of the insulating sliding cover 19. A first arc-shaped plate 23 is fixedly provided on the first cavity 21, and a first through groove 24 that mates with the first insert 14 is provided on the first arc-shaped plate 23. A second arc-shaped plate 25 is fixedly provided on the second cavity 22, and a second through groove 26 that mates with the second insert 15 is provided on the second arc-shaped plate 25. Among them, the guide grooves 20 on both sides of the insulating base 12 are provided between the first jack 42 and the second jack 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 the rotation process of the conductive rod 13, the first insert 14 and the second insert 15 are driven to rotate simultaneously. In order to prevent the insulating sliding cover 19 from blocking the rotation of the first insert 14 and the second insert 15, the first cavity 21 and the second cavity 22 are provided. The first insert 14 rotates inside the first cavity 21, and the second insert 15 rotates inside the second cavity 22. An arc may be generated when the first insert 14 is separated from the first slot 16, and an arc may be generated when the second insert 15 is separated from the second slot 17. Therefore, the first arc-shaped plate 23 is provided inside the first cavity 21, and the second arc-shaped plate 25 is provided inside the second cavity 22. When the conductive rod 13 rotates and drives the first insert 14 to insert into the first slot 16, the conductive rod 13 simultaneously drives the insulating sliding cover 19 to move. The first through groove 24 on the first arc-shaped plate 23 mates with the first slot 16. At the same time, the second insert 15 leaves the second slot 17, and the second arc-shaped plate 25 on the insulating sliding cover 19 covers the second slot 17, which can cut off the arc between the second insert 15 and the second slot 17. When the conductive rod 13 rotates and drives the second insert 15 to insert into the second slot 17, the conductive rod 13 simultaneously drives the insulating sliding cover 19 to move. The second through groove 26 on the second arc-shaped plate 25 mates with the second slot 17. At the same time, the first insert 14 leaves the first slot 16, and the first arc-shaped plate 23 on the insulating sliding cover 19 covers the first slot 16, which can cut off the arc between the first insert 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-shaped plate 23 is located is perpendicular to the plane where the first insert 14 is located. The plane where the second arc-shaped plate 25 is located is perpendicular to the plane where the second insert 15 is located.

[0023] In some embodiments, a push plate 27 is fixedly arranged on the end of the insulating sliding cover 19. A Z-shaped groove 28 is arranged on the push plate 27. A rigid roller 29 matching with the Z-shaped groove 28 is arranged in the Z-shaped groove 28. The rigid roller 29 is rotatably arranged on a push rod 30, and the push rod 30 is fixedly connected with the conductive rod 13. Among them, the Z-shaped groove 28 includes a first horizontal segment, a second horizontal segment and an inclined segment. The inclined segment is connected between the first horizontal segment and the second horizontal segment. The included angle between the first horizontal segment and the second horizontal segment is 135° to 160°, and is usually set to 150°. An arc transition is adopted between the first horizontal segment and the inclined segment, and an arc transition is adopted between the second horizontal segment and the inclined segment. The Z-shaped groove 28 looks like a Z shape from the front view direction and is arc-shaped from the top view. The rigid roller 29 rotates on one end of the push rod 30. The other end of the push rod 30 is fixedly connected with the conductive rod 13. When the conductive rod 13 rotates, it drives the push rod 30 to swing. 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.

[0024] In some embodiments, the driving component includes 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 and fixedly arranged on the end of the conductive rod 13. The driving wheel 33 is coaxially and fixedly arranged on the insulating end sleeve 34. The connecting frame 35 is fixedly arranged on the end of the insulating seat 12. The driving rod 32 is rotatably arranged on the connecting frame 35 and is used to push the driving wheel 33 to rotate. The driving motor 31 is fixedly arranged in the insulating box 11 and the output end is in transmission connection with the driving rod 32. Among them, a connecting frame 35 is fixedly arranged on each insulating seat 12. In the present technology, three insulating seats 12 are arranged in a row. The three connecting frames 35 on the three insulating seats 12 are arranged in a row. The three connecting frames 35 are connected by the same driving rod 32. The driving rod 32 is a worm in the prior art, and the driving wheel 33 is a turbine in the prior art that cooperates with the worm. The conductive rod 13 and the driving wheel 33 are connected through the insulating end sleeve 34, which can effectively prevent the situation of conduction between the conductive rod 13 and the driving wheel 33. 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 a bevel gear set 47 in the prior art.

[0025] In some embodiments, a limiting groove 36 is provided on the insulating base 12. An outer conductive ring 37 connected to the output terminal 10 is arranged in the limiting groove 36. An inner conductive ring 38 is coaxially arranged inside the outer conductive ring 37. The inner conductive ring 38 is fixedly connected to the conductive rod 13 coaxially. End face bearings 39 are arranged between both sides of the inner conductive ring 38 and the inner wall of the limiting groove 36. Among them, 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 arranged. 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 fixedly connected to the conductive rod 13 coaxially. Since the conductive rod 13 pushes the insulating sliding cover 19 to move, the conductive rod 13 is subjected to an axial force. Therefore, end face bearings 39 in the prior art are arranged on both sides of the inner conductive ring 38. The two end face bearings 39 are arranged in the limiting groove 36, and the two end face bearings 39 are sleeved on the conductive rod 13, so that the axial movement of the conductive rod 13 can be restricted.
