Description

Technical Field

[0001] This invention relates to the field of ring network box technology, specifically to a primary and secondary integrated ring network box designed to prevent secondary pressure relief failure. Background Technology

[0002] The integrated primary and secondary ring main unit is an intelligent power distribution device that deeply integrates primary equipment (high-voltage main circuit electrical components) and secondary equipment (control, protection, monitoring, and communication units) in a power system. It is mainly used in 10kV distribution network ring network power supply scenarios to achieve power distribution, fault isolation, and automated management. The integrated primary and secondary ring main unit contains components such as load switches, fuse combinations, or circuit breakers. If a short circuit or insulation breakdown occurs, high-temperature and high-pressure gas will be generated instantaneously. Failure to release the pressure in time can cause the unit to explode, leading to equipment damage or even personal injury. Therefore, a pressure relief device must be installed to release pressure and ensure safety.

[0003] The integrated primary and secondary ring main unit itself is a complete power distribution device assembled from numerous switching device components (such as disconnecting switches, grounding switches, and operating mechanisms) manufactured by power electronic components. Its internal pressure relief device typically involves creating a pressure relief channel at a suitable location within the unit, then covering the channel with a pressure relief plate. One end of the pressure relief plate is usually connected to the ring main unit via a hinge, and the plate is secured to the hinge with metal bolts. The other end of the pressure relief plate is fixed to the ring main unit with plastic bolts. When the internal pressure of the ring main unit becomes excessive, it will force open the plastic bolts, thus... The pressure relief plate opens to release pressure. Under the action of the hinge, the pressure relief plate rotates and will not fly out and collide with other objects. However, after the pressure relief plate is opened, if it falls back too quickly (such as when it resets due to gravity before the pressure relief is completed) or if it is blocked by objects outside the ring network box, the pressure relief plate may cover the pressure relief channel again. If there is still residual high-temperature and high-pressure gas in the cabinet that has not been completely released, or if there is a risk of reignition or secondary gas generation after the failure, the pressure inside the cabinet will accumulate again, which may cause the cabinet to explode again. It will also hinder the gas discharge and heat dissipation during subsequent troubleshooting, increasing safety hazards. Summary of the Invention

[0008] Preferably, the operating mechanism includes a connecting slide rod, with connecting seats slidably sleeved at both ends of the connecting slide rod. The ends of the two connecting seats away from the connecting slide rod respectively cooperate with two U-shaped sliding seats. Spring 1 is sleeved on the outside of both ends of the connecting slide rod.

[0009] Preferably, the locking assembly includes two sets of locking slots and two locking plates. The two sets of locking slots are respectively opened at the top and bottom of the inner wall of the corresponding mounting base. Each set of locking slots is composed of multiple evenly distributed strip grooves. The two locking plates are rotatably installed inside the corresponding connecting base at the end away from the connecting slide rod. The two locking plates cooperate with the multiple strip grooves. T-shaped sliding grooves are opened at the ends of the two locking plates that are close to each other. T-shaped sliders are slidably installed inside the two T-shaped sliding grooves. Transmission rods are rotatably installed on the sides of the two T-shaped sliders that are close to each other. Transmission plates are rotatably installed at the ends of the two transmission rods that are close to each other. Guide rods are slidably sleeved inside both ends of the transmission plate. Two guide rods are fixedly installed inside the corresponding connecting base. Springs are sleeved on the outside of the ends of the two guide rods that are away from the top rod.

[0010] Preferably, the transmission assembly includes a push block and two guide rods. The push block is fixedly installed inside the connecting seat near the transmission plate.

The four connecting plates cooperate with their respective connecting slots.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Through the set locking components, after the pressure relief plate is opened and rotated to its maximum angle, the four locking plates are respectively locked into the corresponding strip grooves to fix the angle of the pressure relief plate, thereby preventing the pressure relief plate from covering the pressure relief channel again. When there is still residual high temperature and high pressure gas inside the ring main body that has not been completely released, and there is a risk of reignition or secondary gas generation after the fault, the components of the numerous switching devices made of power electronic components inside the ring main body can still be depressurized through the pressure relief channel. This solves the problem of secondary explosion of the ring main body caused by the pressure relief plate covering the pressure relief channel again after being opened in the existing technology, avoids obstructing the gas discharge and heat dissipation during subsequent fault diagnosis, and reduces safety hazards.

When the two mounting seats or certain structures in the operating mechanism are damaged, only a part of the structure can be replaced without replacing the entire structure, which helps to save costs.

The pressing block 18 cooperates with the two top rods 19. Springs 20 are sleeved on the outside of the two top rods 19.

[0035] The locking assembly includes two sets of locking slots and two locking plates 22. The two sets of locking slots are respectively opened at the top and bottom of the inner wall of the corresponding mounting base 8. Each set of locking slots is composed of multiple evenly distributed strip grooves 21. The two locking plates 22 are rotatably installed inside the corresponding connecting base 14 at the end away from the connecting slide rod 13. The two locking plates 22 cooperate with the multiple strip grooves 21. T-shaped slide grooves 23 are opened at the ends of the two locking plates 22 that are close to each other.

[0036] The transmission assembly includes a push block 28 and two guide rods 29. The push block 28 is fixedly installed inside the connecting seat 14 near the end of the transmission plate 37. The two guide rods 29 are symmetrically fixedly installed inside the transmission plate 37 near the end of the top rod 19. The two guide rods 29 are slidably fitted with a hinge seat 30. The top ends of the two guide rods 29 are fitted with springs 36. The hinge seat 30 is fixedly installed inside the hinge seat 30. The connecting shaft 31 is rotatably fitted with a push plate 32. One end of the connecting shaft 31 is fitted with a torsion spring 33. The push block 28 and the hinge seat 30 cooperate with each other, and the push plate 32 cooperates with the corresponding top rod 19.

[0037] The two connecting seats 14 are provided with grooves 16 at their close ends, and the two ends of the connecting slide rod 13 are fixedly installed with protrusions 17, which respectively cooperate with the two grooves 16.

[0038] Both ends of the two U-shaped sliding seats 10 are provided with connecting slots 34. Two symmetrically arranged connecting plates 35 are fixedly installed on the ends of the two connecting seats 14 away from the connecting slide rod 13. The four connecting plates 35 cooperate with their respective connecting slots 34.

[0039] Working principle: In use, firstly, the two mounting seats 8 and the two hinges 6 are fixed in the ring network box body 1. Then, the two connecting seats 14 are pushed to move closer to each other along the connecting slide rod 13. At the same time as the two connecting seats 14 move, the locking components and transmission components inside one end of the two connecting seats 14 act accordingly. The movement process of the locking components and transmission components inside one of the connecting seats 14 is as follows: When the connecting seat 14 moves, it drives the locking components and transmission components to move simultaneously. The transmission plate 37 drives the push plate 32 to gradually approach the corresponding top rod 19. The top rod 19 exerts a force on the push plate 32, and the push plate... The transmission plate 37 and the drive plate 32 move in opposite directions relative to the connecting seat 14. The transmission plate 37 slides along the two guide rods 26 and compresses the two springs 27. The push plate 32 gradually approaches the push block 28. When the push block 28 contacts the hinge seat 30, as the transmission plate 37 continues to move, the hinge seat 30 drives the push plate 32 to slide outward and upward along the two guide rods 29 under the action of the push block 28, and compresses the two springs 36. When the hinge seat 30 slides to a certain distance, the push plate 32 rotates along the connecting shaft 31 under the action of the push rod 19. (It should be noted that, according to...) Figure 12As shown, in the initial state, the hinge seat 30 and the push plate 32 are located at the bottom, and the push plate 32 is in a vertical state. After the hinge seat 30 slides to contact the push block 28, the hinge seat 30 and the push plate 32 move upward under the action of the push block 28. At this time, when the push plate 32 is pushed by the push rod 19, it will rotate along the connecting shaft 31. The push plate 32 tilts, and the connecting seat 14 can continue to push, so that the distance the connecting seat 14 moves can be greater than the distance the push rod 19 moves. At the same time as the transmission plate 37 moves, it drives the two transmission rods 25 to move synchronously. The ends of the two transmission rods 25 away from the transmission plate 37 drive their respective T-shaped sliders 24 to slide inside the corresponding T-shaped grooves 23. The two locking plates 22 are then rotated and retracted into the connecting seat 14. The movement process of the locking assembly and transmission assembly inside the other connecting seat 14 is the same as described above. After the four locking plates 22 are respectively inserted into their respective corresponding connecting seats 14, the two connecting seats 14 are respectively inserted into the two U-shaped sliding seats 10. At the same time, the connecting insert plates 35 in the two connecting seats 14 are respectively inserted into their respective corresponding connecting slots 34. Then, the two connecting seats 14 are released. Under the action of the two springs 15, the two connecting seats 14 and the connecting slide rod 13 are installed between the two mounting seats 8. The operating mechanism in this device is detachably connected to the two U-shaped sliding seats 10. When the two mounting seats 8 or some structures in the operating mechanism are damaged, a certain part of the structure can be replaced separately without replacing the entire structure, which helps to save costs.

[0040] Finally, the pressure relief plate 3 is fixedly connected to the two connecting pieces 7 by multiple metal bolts 4, and the other end of the pressure relief plate 3 is fixed to the ring network box body 1 by two plastic bolts 5. When the internal pressure of the ring network box body 1 is too high, it will break open the plastic bolts 5 at both ends of the bottom of the pressure relief plate 3, and the pressure relief plate 3 will open. The ring network box body 1 will then release pressure through the pressure relief channel 2. When the pressure relief plate 3 opens, it rotates through the two hinge pieces 6, which simultaneously drives the two flipping rods 9 to move. The two flipping rods 9 then drive their respective U-shaped sliding seats 10 to slide upward inside the corresponding mounting seats 8. When the pressure relief plate 3 rotates to its maximum angle, the four locking plates 22 respectively lock into their respective strip grooves 21 (it should be noted that, according to Figure 5As shown, multiple strip grooves 21 are rectangular in shape. The two U-shaped sliding seats 10 are initially positioned at the bottom of the two mounting seats 8. The width of the groove at the bottom of the two mounting seats 8 is smaller than the width of the strip grooves 21. At this time, the multiple locking plates 22 are respectively inserted into their respective connecting seats 14. When the two mounting seats 8 move upward into the upper strip grooves 21, the multiple locking plates 22 have room to rotate and can be locked into their respective strip grooves 21, thus fixing the angle of the pressure relief plate 3. When the angle of the pressure relief plate 3 is released, the pressing block 18 is pushed into the connecting slide rod 13. One end of the pressing block 18 acts on the two push rods 19, and the two springs 20 deform accordingly. The two push rods 19 act on the two pushing blocks 19 respectively. The movable plate 32 moves the two transmission plates 37, and the four locking plates 22 retract into their respective connecting seats 14, thus releasing the fixation of the pressure relief plate 3. After the pressure relief plate 3 is opened to its maximum angle, the angle of the pressure relief plate 3 can be fixed to prevent the pressure relief plate 3 from covering the pressure relief channel 2 again. When there is still residual high temperature and high pressure gas inside the ring main body 1 that has not been completely released, and there is a risk of reignition and secondary gas generation after a fault, the components of the numerous switching devices made of power electronic components inside the ring main body 1 can still be depressurized through the pressure relief channel 2. This solves the problem of secondary explosion of the ring main body 1 caused by the pressure relief plate 3 covering the pressure relief channel 2 after being opened in the prior art, avoids obstructing the gas discharge and heat dissipation during subsequent fault diagnosis, and reduces safety hazards.
