Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage vacuum distribution cabinets, and more specifically, to a mine-used intelligent flameproof and fully insulated combined high-voltage vacuum distribution device. Background Art

[0002] A distribution cabinet is an electrical product that plays roles such as on-off, control, or protection in the power generation, transmission, distribution, power conversion, and consumption of a power system. The application fields of high-voltage vacuum distribution cabinets are mainly the central, panel, and mining area substations in coal mines, the distribution points for main haulage belts, crossheading belts, and heading faces in roadways, temporary distribution points, and other distribution areas with harsh environments and explosion-proof requirements.

[0003] Chinese Patent Application No. CN201410419414.8 discloses a side-mounted mine-used flameproof high-voltage vacuum distribution device, which includes a disconnector, a static contact, a busbar, a second insulator, a second bushing, a third bushing, a third conductor, a third rotating shaft, a vacuum interrupter, a flexible connection, a first insulator, a permanent magnet mechanism, a current transformer, a lightning arrester, an insulator pull rod, a second rotating shaft, a toggle arm, an insulating partition, a circuit breaker chamber door, a microcomputer integrated protection, a discharge switch, a first bushing, a first conductor, a connecting plate, and a first rotating shaft.

[0004] In the above technical solution, a disconnector is arranged in the busbar chamber, which can conveniently cut off the connection with high voltage to form an air-insulated break. A discharge switch is arranged in the cable chamber to avoid the potential accident hazard of generating sparks when manually hanging a grounding wire. Before the existing high-voltage vacuum distribution cabinets are used, a series of cumbersome operation steps are required. First, the operator must open the lock hole, then insert a sliding rod socket wrench into the grounding disconnection hole and rotate to disconnect the grounding. Then, use the sliding rod socket wrench again to insert it into the on-off switch hole to close and energize. After completing these steps, the lock hole needs to be locked again, and the start switch of the distribution cabinet needs to be opened to make the distribution cabinet work normally for power transmission. When the distribution cabinet finishes working, the power transmission needs to be stopped first according to the reverse steps, then the power supply needs to be disconnected, and finally the grounding needs to be re-closed. The entire process not only consumes time and effort but also increases the risk of misoperation. Moreover, in the design of traditional distribution cabinets, in case of an emergency, through the above steps of operation, not only does the response speed slow down, but also the sudden situation cannot be quickly and effectively handled.

[0031] Usage steps of the present invention: When the intelligent explosion-proof fully insulated combined high-voltage vacuum distribution device for mine use is in use, in the initial state, the sliding column 24 is squeezed and stretched by the second short flat rail 20 to compress the third spring 31. At this time, the lower ball head 13 is in matching contact with the lower ball shell 12.

The surface of the lower ball head 13 is clamped by the elastic piece 61 (the elastic force of the elastic piece 61 is less than the elastic force of the third spring 31, and the elastic force of the elastic piece 61 is also less than the elastic force of the second spring 30). The upper ball head 9 and the upper ball shell 8 are disconnected and separated. When the power distribution cabinet 1 needs to work, first open the cabinet door 43, and manually rotate the key cylinder 47 clockwise. At this time, the threaded rod 42 rotates forward towards the inside of the operation plate 40 under the action of the threaded ring 41. Since the rotating block 49 is rotationally connected to the fixed ring 39, at this time, the rotating block 49 rotates and moves forward to drive the fixed rod 38 to move. The fixed rod 38 moves to drive the trapezoidal block 37 to move and squeeze one of the sliding rods 26. During the movement of the trapezoidal block 37, it also drives the slider 36 to move inside the sliding frame 35. The sliding rod 26 moves to drive the movable plate 14 to move and compress the first spring 27. The movable plate 14 moves to drive the upper rail plate 15 and the lower rail plate 16 to move simultaneously. Since the length of the first long flat rail 17 is greater than the length of the second short flat rail 20, when the sliding column 24 touches the bottom surface of the lower rail plate 16, at this time, the sliding column 24 is reset under the action of the third spring 31 and drives the lower ball head 13 to separate from the lower ball shell 12, causing the grounding to be disconnected. At this time, the bottom surface of the upper sliding column 29 still moves on the surface of the first long flat rail 17. As the movable plate 14 continues to move, when the upper sliding column 29 is squeezed by the surface of the inclined rail 18, the upper sliding column 29 moves upward to drive the upper ball head 9 to move upward and squeeze the elastic piece 61 (an insulating rubber sleeve is installed on the surface of the elastic piece 61). As the upper ball head 9 moves upward and is in matching contact with the upper ball shell 8 to stretch the second spring 30, the closing is completed. At this time, the upper sliding column 29 is in contact with the surface of the first short flat rail 19, and the sliding column 24 is in contact with the bottom surface of the second long flat rail 22. After the upper ball head 9 and the upper ball shell 8 are in contact and the closing is completed, at this time, the position of the lock hole 50 exactly corresponds to the position of the lock rod 52. Then manually insert the lock rod 52 into the lock hole 50 to lock the key cylinder 47. Then manually press the start switch 46. At this time, the main circuit supplies power to the electrical equipment through the upper sliding column 29, the upper ball head 9, the upper ball shell 8, the upper conductive sheet 7, the closing and separating conductive plate 6 and the conductive column 34. At this time, the power distribution cabinet 1 works normally. When the power distribution cabinet 1 finishes working, first press the stop switch 45, and then pull out the lock rod 52 from the lock hole 50. At this time, manually rotate the key cylinder 47 counterclockwise. The key cylinder 47 moves back to drive the threaded rod 42 to reset. At this time, the fixed ring 39 drives the fixed rod 38 and the trapezoidal block 37 to move back following the rotating block 49. At this time, the movable plate 14 moves back under the action of the first spring 27 to drive the upper rail plate 15 and the lower rail plate 16 to move back simultaneously. When the movable plate 14 moves back during the reset process,The upper sliding column 29 is reset under the action of the second spring 30, and the upper ball head 9 is reset and separated from the upper ball shell 8 to achieve disconnection. When the movable plate 14 completes the reset movement, the lower sliding column 24 is squeezed so that the lower ball head 13 is matched with the lower ball shell 12 and contacts, and the solid line is grounded. The scheme moves the upper rail plate 15 and the lower rail plate 16 at the same time through the movement of the movable plate 14, so that the lower ball head 13 is separated from the lower ball shell 12, and the grounding is first achieved. Disconnection, as the movable plate 14 continues to move, the upper sliding column 29 is squeezed by the surface of the inclined rail 18, and the upper sliding column 29 moves upward, and the upper ball head 9 moves upward to match the upper ball shell 8 to complete the closing. Compared with the traditional distribution cabinet 1, there is no need to use a sliding rod sleeve The barrel wrench is inserted into the grounding disconnect hole and rotated to disconnect the grounding. There is no need to use a sliding rod socket wrench to insert into the on-off switch hole to close the switch and energize it. The whole process not only saves time and effort, but also reduces the risk of misoperation. When encountering an emergency, it can be adjusted without the operation of professionals. Not only is the response speed fast, but also the emergency can be handled quickly and effectively. The spherical design of the lower ball head 13 and the upper ball head 9, and the hemispherical shell design of the lower ball shell 12 and the upper ball shell 8, compared with the traditional duckbill switch-type closing and grounding, reduces the wear caused by long-term frequent disconnection of the connection switch, which not only ensures the stability of the power distribution cabinet 1 during the power transmission process, but also extends the service life of the power switch of the distribution cabinet 1.

[0032] Example 2: Please refer to Figure 1 - Figure 11, which is different from the basis of Embodiment 1. A splined keyboard 56 is arranged inside the key barrel 47. A connecting rod 48 is fixedly installed on the surface of the splined keyboard 56. An upper gear 53 is fixedly installed on the surface of one end of the connecting rod 48. A crank 54 is fixedly installed on the surface of the upper gear 53. A plurality of spline teeth 55 are fixedly connected to the inner wall of the key barrel 47. The splined keyboard 56 is spline-connected with the key barrel 47 through the spline teeth 55. A rotating cavity 57 is arranged inside the key barrel 47. When the connecting rod 48 is pulled outwards, the splined keyboard 56 enters the rotating cavity 57, so that the upper gear 53 and the lower gear 59 are engaged with each other. Production is carried out according to the lengths of the connecting rod 48 and the rotating cavity 57, and the upper gear 53 and the lower gear 59 are just engaged with each other. The rotating cavity 57 is located on one side of the spline teeth 55. An energy storage device 60 is fixedly installed on the inner side surface of the operation panel 40. A rotating shaft 58 that drives the energy storage device 60 to work is rotatably connected to the surface of the operation panel 40. The energy storage device 60 is a conventional energy storage device 60 in the prior art. When the energy storage device 60 works for energy storage, manually pull the connecting rod 48 out of the key barrel 47. At this time, the splined keyboard 56 moves outwards with the connecting rod 48 and disengages from the spline teeth 55. When the splined keyboard 56 moves into the rotating cavity 57, the upper gear 53 and the lower gear 59 are engaged with each other at this time. Manually rotate the crank 54. At this time, the upper gear 53 rotates to drive the lower gear 59 to rotate, and the rotating shaft 58 rotates to drive the energy storage device 60 to work to achieve energy storage. Compared with the energy storage operation of the traditional power distribution cabinet 1, there is no need to rotate the energy storage through the existing sleeve inserted into the energy storage operation hole. Through the integrated operation structure design of the power distribution cabinet 1, the operations of grounding disconnection, switching on, and energy storage are realized, so that the power distribution cabinet 1 can work quickly to realize power transmission.

[0033] A lower gear 59 that matches the upper gear 53 is fixedly installed on the surface of one end of the rotating shaft 58.

[0034] Steps of using the present invention: When the intelligent flameproof fully-insulated combined high-voltage vacuum distribution device for mine use is in use, in the initial state, the flower keyboard 56 is spline-connected to the key barrel 47 through the spline teeth 55. The upper gear 53 and the lower gear 59 are disengaged from each other. First, manually rotate the crank 54. At this time, the upper gear 53 rotates to drive the connecting rod 48 to rotate. The flower keyboard 56 follows the connecting rod 48 to rotate and drives the key barrel 47 to rotate. The threaded rod 42 rotates forward towards the inside of the operation plate 40 under the action of the threaded ring 41. Then, the grounding disconnection and closing are realized through the steps of Embodiment 1. In Embodiment 1, the entire on-off operation process of the power distribution cabinet 1 is time-saving and labor-saving, reducing the risk of misoperation. After the grounding disconnection and closing are completed, it is also necessary to manually store energy for the energy storage device 60. At this time, the locking rod 52 is inserted into the locking hole 50 to lock the key barrel 47. When the energy storage device 60 works for energy storage, manually pull the connecting rod 48 out of the key barrel 47. At this time, the flower keyboard 56 follows the connecting rod 48 to move outwards and disengages from the spline teeth 55. When the flower keyboard 56 moves into the rotating cavity 57, at this time, the upper gear 53 and the lower gear 59 are engaged with each other. Manually rotate the crank 54. At this time, the upper gear 53 rotates to drive the lower gear 59 to rotate. The rotating shaft 58 rotates to drive the energy storage device 60 to work for energy storage. Compared with the energy storage operation of the traditional power distribution cabinet 1, there is no need to rotate the existing sleeve into the energy storage operation hole for energy storage. Through the integrated operation structure design of the power distribution cabinet 1, the grounding disconnection, closing and energy storage process operations are realized, enabling the power distribution cabinet 1 to work quickly to realize power transmission.
