Technical Field
[0001] The utility model relates to the technical field of box-type transformer substations, in particular to a high-protection box-type transformer substation. Background Art
[0002] Box-type substation, also called prefabricated substation or prefabricated substation. It is a kind of factory-prefabricated indoor and outdoor compact distribution equipment that is arranged in a certain wiring scheme with high-voltage switchgear, distribution transformer and low-voltage distribution device. It combines transformer step-down, low-voltage distribution and other functions organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation.
[0003] The box-type substation is protected by the box body when it is working normally. However, when the substation is maintained, the box door of the substation needs to be opened for operation. At this time, the inside of the box is exposed and it is easy for unauthorized personnel to approach and cause danger. Therefore, we propose a high-protection box-type substation. Utility Model Content
[0004] The purpose of the utility model is to provide a high-protection box-type substation, in which a rotatable baffle frame is installed at the front end of the substation room of the box body. During normal use, the baffle frame is in a vertical state and is locked. When the substation needs to be inspected and maintained, the baffle frame can be rotated to a horizontal state and locked. The baffle frame is used to block irrelevant personnel from approaching, reducing the danger during inspection and maintenance. It has a high safety protection effect and solves the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-protection box-type substation, comprising a box body and a retaining frame, the retaining frame is C-shaped, and both sides are rotatably installed at the front end of the transformer room of the box body through a rotating shaft, and the retaining frame is arranged in a vertical state; both sides of the retaining frame are provided with plug rods passing through the through holes on the surface of the retaining frame at the position above the rotating shaft, and the outer ring of the plug rod on one side close to the inner wall of the box body transformer room is fixed with a butt plate, and the outer ring of the plug rod between the butt plate and the other side of the retaining frame is sleeved with a spring, and the surface of the inner wall of the box body transformer room just above and in front of the rotating shaft is provided with a socket, and the end of the plug rod is inserted into the socket just above the rotating shaft to achieve locking of the retaining frame.

[0007] Optionally, both side surfaces of the baffle frame are rotatably connected with connecting rods, and magnets are rotatably connected and fixed to the ends of the connecting rods.
[0008] By adopting the above technical solution, after the baffle frame is rotated to the front end and locked, the connecting rod can be rotated to the outside and the magnet at its end is adsorbed on the surface of the door to achieve a secure locking of the door.
[0009] Optionally, the connecting rod is rotatably connected to the surface of the baffle frame via a damping hinge, and the magnet is rotatably mounted on the end of the connecting rod via a movable hinge.
[0010] By adopting the above technical solution, when the connecting rod is rotated and retracted, due to the self-locking effect of the damping hinge, the locking state of the baffle frame when it is vertically stored can be kept unchanged.
[0011] Optionally, a support plate is fixed on the surface of the inner wall of the box transformer room below the baffle frame, and the support plate is close to the bottom of the baffle frame.

[0015] Optionally, both sides of the front end of the transformer room of the box body are provided with box doors through hinges, and the box doors block the front end of the transformer room when they are closed.
[0016] By adopting the above technical solution, the box door locks the front end of the substation room of the box-type substation.
[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0018] 1. The technical solution of the present application is to install a rotatable baffle frame at the front end of the transformer room inside the box body. During normal use, the baffle frame is in a vertical state and is locked. When the substation needs to be inspected and maintained, the baffle frame can be rotated to a horizontal state and locked. The baffle frame is used to prevent unauthorized personnel from approaching, thereby reducing the danger during inspection and maintenance and having a high safety protection effect.

The technical solution of the present application is that a connecting rod is rotatably connected to the two side surfaces of the baffle frame through a damping hinge, and the end of the connecting rod is rotatably connected to a magnet. When the door is opened and the baffle frame is rotated to the front end to be locked, the connecting rod is rotated out and the magnet at its end is adsorbed on the surface of the door, which can achieve the purpose of stabilizing the locking of the door and further improve the protection effect of the door.

[0026] See also Figure 1-4 The utility model provides a technical solution: a high-protection box-type substation, including a box body 1 and a retaining frame 2, the substation room of the box body 1 is arranged at the front end, and its dry-type transformer is installed inside the substation room at the front end, the distribution room is located on both sides of the substation room, and the opening of the distribution room faces the rear end, and box doors 12 are installed on both sides of the front end of the substation room through hinges. When the box door 12 is closed, the front end of the substation room is blocked. During maintenance and overhaul, the box door 12 is opened to expose the substation room.
[0027] The baffle frame 2 is C-shaped, and is placed in a vertical position inside the transformer room, and the lower part of both sides thereof is rotatably mounted at the front end of the transformer room through the rotating shaft 21. In order to achieve a stable locking state, the inner wall surface of the transformer room just above and just in front of the rotating shaft 21 is provided with a plug hole 13, and a through hole 22 is transversely provided on the surface of the baffle frame 2 just above the rotating shaft 21. The cross section of the baffle frame 2 is a hollow structure, and the through holes 22 allow the upper part of the rotating shaft 21 on both sides to be locked. The baffle frames 2 are all slidably penetrated by the plug rod 3 laterally. The outer ring of the plug rod 3 located inside the baffle frame 2 is surrounded and fixed with a stop plate 32. The stop plate 32 is close to one side of the inner wall of the transformer room, and the outer ring of the plug rod 3 between the stop plate 32 and the inner wall on the other side of the baffle frame 2 is sleeved with a spring 33, which will push the plug rod 3 toward the socket 13 just above the rotating shaft 21. Since the diameter of the plug rod 3 is smaller than the inner diameter of the socket 13, the end of the plug rod 3 will be pushed into the socket 13, finally achieving the locking of the baffle frame 2 in the vertical state.
[0028] A pull ball 31 is welded and fixed at the end of the plug rod 3. The diameter of the pull ball 31 is larger than that of the plug rod 3. When the box door 12 is opened for inspection and maintenance, the plug rod 3 can be pulled by the pull ball 31, so that the end of the plug rod 3 is first pulled out from the upper socket 13 to release the lock on the baffle frame 2. The baffle frame 2 can be rotated to the horizontal front end position, and the plug rod 3 is aligned with the front end socket 13, and then inserted into the front end socket 13 under the action of the spring 33 to lock the baffle frame 2 in a horizontal state. In order to achieve stable horizontal fixation, a support plate 11 is fixed to the surface of the inner wall of the transformer room of the box body 1 below the baffle frame 2. The support plate 11 is close to the bottom of the vertical baffle frame 2. When the baffle frame 2 is rotated to the horizontal state, it can be supported on the bottom of the baffle frame 2 to improve its horizontal fixing stability. At this time, the baffle frame 2 serves the purpose of isolation and protection to prevent unrelated personnel from approaching and causing danger.
[0029] During maintenance and inspection, if there is wind blowing, the box doors 12 opened on both sides may shake and collide. Therefore, the two side surfaces of the baffle frame 2 are rotatably connected with connecting rods 4 through damping hinges 41, and the end of the connecting rod 4 is rotatably fixed with a magnet 42 through a movable hinge. After the baffle frame 2 is locked horizontally, the connecting rod 4 can be rotated and unfolded, and the magnet 42 at its end is close to the box door 12 and adjusted to a suitable angle to be adsorbed on the surface of the box door 12, so as to achieve stable locking of the box door 12 and avoid shaking caused by wind. Since the damping hinge 41 is connected to the connecting rod 4, when the baffle frame 2 is locked in the vertical state, the damping hinge 41 can achieve locking of the connecting rod 4 in the vertical state.
[0030] When in use, the transformer of the substation is installed in its transformer room. During normal use, the box door 12 is directly closed and locked for work. When maintenance is required, the box door 12 is first locked and opened. After the maintenance personnel enter, they first pull the plug rod 3 outward through the pull ball 31, so that the end of the plug rod 3 is pulled out from the socket 13 above the rotating shaft 21 and the spring 33 is compressed. Then the blocking frame 2 can be rotated to the front. The blocking frame 2 is first supported on the surface of the support plate 11 to maintain the lateral state of the blocking frame 2. In order to improve the lateral fixing stability of the blocking frame 2, the end of the plug rod 3 is aligned with the socket 13 at the front end of the rotating shaft 21. Under the action of the spring 33, the end of the plug rod 3 is inserted into the socket 13 at the front end of the rotating shaft 21 again to limit the blocking frame 2, and the box-type During the inspection and maintenance of the substation, in order to lock the opened box door 12, the connecting rods 4 on both sides can be rotated around the damping hinges 41 to open, and the magnets 42 at the ends thereof are close to the surface of the box door 12 and rotated to a suitable angle, and then adsorbed on the surface of the box door 12, which can stabilize the box door 12 and prevent it from shaking due to wind. After the inspection and maintenance work is completed, the magnets 42 are first no longer adsorbed on the surface of the box door 12, and the connecting rods 4 are retracted by rotating around the damping hinges 41, and then the plug rod 3 is pulled to move it out of the socket 13 at the front end of the shaft 21, and the shaft 21 of the baffle frame 2 is rotated to a vertical state, and the plug rod 3 is then extended into the socket 13 above the shaft 21 under the resetting action of the spring 33, so as to lock the baffle frame 2, and finally the personnel can walk out and close the locked box door 12.
