Description

Technical Field

[0001] The present invention relates to the technical field of ring network cabinets, and in particular to an intelligent ring network cabinet with a fault automatic power-off function. Background Art

[0002] A ring main unit (RMU) is a group of electrical transmission and distribution equipment installed in a metal or non-metallic insulating cabinet or made into an assembled interval ring main unit. Its core parts use load switches and fuses. It has the advantages of simple structure, small size, low price, improved power supply parameters and performance, and power supply safety. It is widely used in distribution stations and box-type substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories and enterprises.

[0003] Based on the above, a search revealed that the Chinese invention patent publication number is: (CN 114400509 A) An energy-saving ring network cabinet with automatic heat dissipation function, comprising a cabinet body, a first cabinet door and a second cabinet door are provided on the cabinet body, and a heat dissipation port is provided on the first cabinet door, and a heat dissipation fan is fixedly installed on the inner wall of the first cabinet door. The energy-saving ring network cabinet with automatic heat dissipation function described in this invention belongs to the field of ring network cabinets. The dustproof structure can effectively prevent dust and ensure the normal operation of the internal components of the ring network cabinet. The rotating frame and the rotating seat are used to rotate the rotating frame to ensure that dust does not enter the interior of the ring network cabinet during cleaning. The placement structure is provided to place maintenance tools and other items during maintenance, so that the staff can take them nearby for use. At the same time, the placement structure can be stored and does not occupy extra space when not in use. The support frame is used to ensure the stability of the sliding plate when in use, and does not affect the normal storage of the sliding plate when not in use. At the same time, the support frame can be disassembled for easy replacement. The above-mentioned energy-saving ring network cabinet with automatic heat dissipation function effectively prevents dust by setting a dustproof net, but the patent has the problem that the heat dissipation fan will extract water molecules from the outside into the inside of the ring network cabinet when it is working, and when the dustproof net needs to be removed, there is still a problem of not being able to remove it. When a circuit breaker inside the ring network cabinet fails and is disconnected, it is impossible to locate the disconnected circuit breaker in time, and the moisture from the ground that has been in contact with the ground for a long time will also invade the interior of the ring network cabinet, thereby causing moisture inside the ring network cabinet. When the water molecules inside reach a certain level, it will also affect the normal operation of the internal components of the ring network cabinet. Summary of the Invention

[0030] See also Figure 2 In order to lift the ring network cabinet body 1, the lifting mechanism 4 in this embodiment includes a bottom plate 401 fixed to the lower surface of the ring network cabinet body 1, a mounting frame 403 is fixed to the upper surface of the bottom plate 401, an electric push rod 402 located on the back of the cable tray 2 is fixed inside the mounting frame 403, a connecting plate 404 is fixed to the outer side of the output shaft of the electric push rod 402, and the left and right sides of the lower surface of the connecting plate 404 are hinged with first drive rods 405 through hinge shafts, and the two first drive rods 405 are away from the connecting rods. One end of the plate 404 is hinged with a mounting seat 406 through a hinge shaft. When moving, the first drive rod 405 pushes the two mounting seats 406 hinged to it to move backwards. The two mounting seats 406 drive the protrusions on the lower surface to move backwards inside the convex groove. The inside of the two mounting seats 406 is hinged with a second drive rod 407 through a hinge shaft. The outer side of the bottom plate 401 is covered with a cabin 408, and the bottom plate 401 moves inside the cabin 408. A sliding bar 409 is fixed to the bottom wall of the inner cavity of the cabin 408.

[0031] The lifting mechanism 4 also includes a support rod 410 fixed on the lower surface of the base plate 401, and the outer side of the support rod 410 is provided with a sleeve rod 411 fixed to the bottom wall of the inner cavity of the cabin 408. The lower surfaces of the two mounting seats 406 are fixed with protrusions, and the interior of the slide 409 is provided with a convex groove for the two protrusions to move and to fit with the clearance. The left and right sides of the convex groove are in a closed state. Four moving wheels are fixed on the lower surface of the cabin 408. By arranging four moving wheels on the lower surface of the cabin 408, the movement of the entire ring network cabinet body 1 is facilitated. The shape of the cabin 408 is a rectangular parallelepiped with a hollow interior and a missing upper surface.

[0032] Therefore, the lifting mechanism 4 is installed on the lower surface of the ring main unit 1 and the bottom plate 401 is lifted up by the second driving rod 407 to control the distance between the lower surface of the ring main unit 1 and the ground.

[0033] See also Figure 3-4In order to achieve the purpose of heat dissipation and facilitate the removal of the dust screen 506 and the dehumidification layer 505, the heat dissipation mechanism 5 in this embodiment includes a connecting pipe 501 connected to the left side of the ring network cabinet body 1, a heat dissipation fan 502 is fixed inside the connecting pipe 501, an air inlet pipe 503 is connected to the right side wall of the inner cavity of the ring network cabinet body 1, a baffle 504 is fixed inside the air inlet pipe 503, an air inlet hole is opened inside the baffle 504, a dehumidification layer 505 movable inside the air inlet pipe 503 is attached to the right side of the baffle 504, and a dehumidification layer 505 is attached to the right side of the dehumidification layer 505. The dustproof net 506 is movable inside the air inlet pipe 503. The dustproof net 506 and the dehumidification layer 505 can filter the air drawn into the ring network cabinet body 1 and absorb the moist air inside. The outer side of the air inlet pipe 503 is provided with a disassembly cover 507. The right side wall of the inner cavity of the disassembly cover 507 is fixed with two springs 508 that are attached to the right side of the dustproof net 506. The outer side of the disassembly cover 507 is fixed with four clamping blocks 509. The right side of the ring network cabinet body 1 is fixed with a clamping seat 510 that is mounted on the outer side of the disassembly cover 507.

[0034] The right side wall of the inner cavity of the card seat 510 is provided with a positioning groove for the four card blocks 509 to be plugged in. The interior of the card seat 510 is provided with a mezzanine for the four card blocks 509 to rotate. The right side wall of the inner cavity of the disassembly cover 507 is provided with no less than two inclined holes, and the inclined holes face the ground. The design of the inclined holes can effectively prevent water droplets from flowing in. The dehumidification layer 505 is an activated carbon layer, which absorbs water and wind in the air through the activated carbon layer. The baffle 504 is in the shape of a ring. An exhaust outlet is provided on the left side wall of the inner cavity of the ring network cabinet body 1 and at the right end of the connecting pipe 501.

[0035] Therefore, the above-mentioned heat dissipation mechanism 5 is connected to the connecting pipe 501 through the air inlet end of the heat dissipation fan 502 to extract the heat inside the ring network cabinet body 1. By removing the disassembly cover 507 from the outside of the air inlet pipe 503, the internal dustproof net 506 and dehumidification layer 505 can be removed.

[0036] See also Figure 5-6 In order to serve as an alarm positioning, the alarm mechanism 6 in this embodiment includes a power supply pile 601 fixed on the left side wall of the inner cavity of the ring network cabinet body 1, and the positive end of the power supply pile 601 is welded with a first wire 602, and the end of the first wire 602 away from the power supply pile 601 is electrically connected to an alarm 603 fixed on the front of the wiring board 2. The alarm 603 is a prior art and is not described here in detail. The internal electrical connection of the alarm 603 is a second wire 604, and the end of the second wire 604 away from the alarm 603 is welded with a first conductive block 605 fixed on the front of the insulating handle 7, and the negative end of the power supply pile 601 is welded with a third wire 606, and the end of the third wire 606 away from the power supply pile 601 is welded with a second conductive block 607 fixed on the front of the short-circuit switch 3.

[0037] It should be noted that by fitting the first conductive block 605 and the second conductive block 607 together, the second wire 604 and the third wire 606 are electrically connected. At this time, the power supply pile 601, the first wire 602, the alarm 603, the second wire 604 and the third wire 606 form a loop, which can supply power to the alarm 603. At the same time, through the connecting line and the second wire 604 or the third wire 606, a row of three alarms 603 form a parallel loop, thereby realizing that the first conductive block 605 and the second conductive block 607 on each short-circuit switch 3 are fitted together to form a separate loop.

[0038] The outside of the first wire 602 and the third wire 606 are welded with connecting wires, and are electrically connected to the two alarms 603 on the right. The two connecting wires are electrically connected to the first wire 602 and the third wire 606 respectively, so that the middle alarm 603 forms a separate loop. Similarly, the alarm 603 on the right is electrically connected to the two connecting wires, and the first conductive block 605 and the second conductive block 607 on the right are both brass blocks, which play a conductive role. The rated voltage of the power pile 601 does not exceed twenty-four volts. There are three power piles 601, and they are evenly distributed on the left wall of the inner cavity of the ring network cabinet body 1.

[0039] Therefore, the alarm mechanism 6 is provided with an alarm 603 above each short-circuit circuit breaker 3. When one of the alarms 603 sounds, it means that the circuit breaker below the alarm 603 is in the disconnected state.

[0040] The working principle of the above embodiment is:

[0041] (1) By installing a lifting mechanism 4 on the lower surface of the ring network cabinet body 1, the distance between the lower surface of the ring network cabinet body 1 and the ground is controlled. The specific usage method is that the output shaft of the electric push rod 402 is extended to push the connecting plate 404 to move downward. Through the hinged action, the two first driving rods 405 away from one end of the connecting plate 404 move backward when the connecting plate 404 moves downward, that is, the first driving rod 405 pushes the two mounting seats 406 hinged to it to move backward when moving. The two mounting seats 406 drive the protrusions on the lower surface to move backward inside the convex groove. At the same time, the ends of the two second driving rods 407 connected to the mounting seats 406 move backward accordingly. When the second driving rods 407 move backward, the bottom plate 401 is lifted by the second driving rods 407, and the bottom plate 401 moves upward to pull the support rod 410 out from the inside of the sleeve rod 411. At this point, the lifting and lowering of the ring network cabinet body 1 is completed, and the movement of the entire ring network cabinet body 1 is facilitated by arranging four moving wheels on the lower surface of the cabin 408.

[0042] (2) When the ring network cabinet body 1 is working, heat is generated. The heat inside the ring network cabinet body 1 is extracted through the air inlet end of the heat dissipation fan 502 connected to the connecting pipe 501, and the hot air is discharged to the outside from the air outlet end of the heat dissipation fan 502. By setting a dustproof net 506 and a dehumidification layer 505 inside the air inlet pipe 503, the air extracted into the ring network cabinet body 1 can be filtered and the wet air inside can be adsorbed, which effectively improves the dryness inside the ring network cabinet body 1 and reduces the penetration of external dust. When it is necessary to clean and replace the dustproof net 506 and the dehumidification layer 505, rotate the disassembly cover 507 to remove the cover 507. When rotating, the four outer clamping blocks 509 rotate inside the interlayer inside the clamping seat 510. After the four outer clamping blocks 509 of the disassembly cover 507 are aligned with the four positioning holes inside the clamping seat 510, the elastic force of the two springs 508 pushes the disassembly cover 507 to move to the right. At this time, the clamping blocks 509 can be moved out from the inside of the positioning holes, and then the disassembly cover 507 can be removed from the outside of the air inlet pipe 503, and the internal dustproof net 506 and dehumidification layer 505 can be removed. At this point, the disassembly of the dustproof net 506 and the dehumidification layer 505 and the heat dissipation treatment of the ring network cabinet body 1 are completed.

[0043] (3) When a short-circuit breaker 3 inside the ring network cabinet body 1 trips due to a short circuit or line damage, the rubber handle inside the short-circuit breaker 3 pops down, driving the first conductive block 605 to move in an arc along the direction of the second conductive block 607. That is, when the first conductive block 605 fits with the second conductive block 607, the power supply pile 601, the first wire 602, the second wire 604, the alarm 603, the first wire 602, the second conductive block 607 and the third wire 606 form a closed loop. At this time, through the effect of electrical connection, when the insulating handle 7 of the short-circuit breaker 3 pops down, the power supply pile 601 01 can power the alarm 603, and an alarm 603 is provided above each short-circuit circuit breaker 3. When one of the alarms 603 sounds, it means that the circuit breaker below the alarm 603 is in a disconnected state, and the three alarms 603 on the same row form a parallel circuit through the electrical connection. When a short-circuit circuit breaker 3 is disconnected, it drives the first conductive block 605 to contact the second conductive block 607, so that the corresponding alarm 603 forms a separate closed loop, which makes it easier for maintenance personnel to quickly locate the disconnected short-circuit circuit breaker 3 and realize rapid diagnosis of its fault after power failure.
