Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] like Figures 1-7 As shown, the integrated primary and secondary ring network box pressure relief device includes a ring network box 1. Several heat dissipation slots 2 are provided at the left end of the ring network box 1. A first cabinet door 3 and a second cabinet door 4 are connected to the left and right ends of the ring network box 1 via hinges. A rectangular frame 7 is fixedly inserted into the upper end of the ring network box 1. Several electrical cabinets 12 are installed inside the ring network box 1. The electrical cabinets 12 are either high-voltage or low-voltage incoming line cabinets. A lock 5 is provided at the front end of the second cabinet door 4. The lock 5 is existing technology. A locking rod 6 that can move left and right is provided inside the lock 5. The lock 5 and the locking rod 6 work together to open and close the first cabinet door 3 and the second cabinet door 4. The left end of the locking rod 6 is movably inserted into the first cabinet door 3. A first rotating component 8 is provided at the upper end of the rectangular frame 7. Rectangular slots 121 are provided at the upper ends of the several electrical cabinets 12. Through slots 122 are provided on the lower walls of the several rectangular slots 121. A second rotating component 13 is provided within each of the several rectangular slots 121.
[0028] The high pressure gas can be discharged through the cooperation of the rectangular frame 7, the first rotating part 8 and the second rotating part 13. Specifically, the second rotating part 13 comprises a second rotating plate 131 arranged in the rectangular groove 121, the front end and the rear end of the second rotating plate 131 are provided with rotating shafts 132, the two rotating shafts 132 are movably inserted into the rectangular groove 121, the lower end right part of the second rotating plate 131 is provided with a second magnet 133 for fixing the second rotating plate 131 in the rectangular groove 121, the first rotating part 8 comprises a first rotating plate 81 rotatably connected to the upper end of the rectangular frame 7 through a rotating shaft, the lower end front part of the first rotating plate 81 is provided with a first magnet 83 for fixing the first rotating plate 81 on the rectangular frame 7, and the lower end of the first rotating plate 81 is provided with a groove 82 for reducing the weight of the first rotating plate 81. When the high pressure gas is generated due to the failure of the electric cabinet 12, the high pressure gas pushes the second rotating plate 131 to rotate to the left, so that the high pressure gas can be discharged out of the electric cabinet 12, and then the high pressure gas pushes the first rotating plate 81 to rotate backward, so as to discharge the high pressure gas in the ring net box 1 and the electric cabinet 12, thereby avoiding the explosion of the ring net box 1 and the electric cabinet 12 due to the high pressure gas, and improving the safety.
[0029] In addition, when one electric cabinet 12 is accidentally damaged, other electric cabinets 12 may also be damaged to generate high pressure gas.
