[0029] The substation in the embodiment of the present invention integrates low-voltage equipment, transformer equipment and high-voltage equipment into an integrated structure, closely combines the Internet of Things low-voltage switchgear with the transformer box, and directly assembles the bushing-type permanent magnetic vacuum circuit breaker on the transformer box, thereby improving the compactness of the box transformer and reducing the land area occupied by the box transformer.
[0030] like Figure 2 As shown, specifically, the embodiment of the present invention further discloses a specific structure of a bushing-type permanent magnetic vacuum circuit breaker, which includes: a vacuum circuit breaker switch body 402, an incoming line terminal 405, a moving contact soft connecting piece 403, a moving contact connecting rod 404 and an outgoing line terminal 401, the vacuum circuit breaker is connected to the permanent magnetic mechanism through an insulating bushing 407 and an insulating connecting rod 406, the permanent magnetic mechanism includes a permanent magnetic mechanism panel 409, a permanent magnetic mechanism action connecting rod 408, a closing position sensor 410, a position sensor 411, a permanent magnetic operating mechanism 412, a permanent magnetic mechanism excitation coil terminal 413, and a position sensor terminal 414, the permanent magnetic operating mechanism 412 is connected to the insulating connecting rod 406 through the permanent magnetic mechanism action connecting rod 408, and the insulating connecting rod 406 is The top end is connected to the moving contact connecting rod 404 of the vacuum circuit breaker switch body 402, the upper end of the moving contact connecting rod 404 is connected to the moving contact in the vacuum circuit breaker switch body 402, the permanent magnet operating mechanism 412 is connected to the permanent magnet mechanism excitation coil terminal 413, and the external permanent magnet mechanism excitation power supply 415 inputs pulse power excitation to the permanent magnet mechanism excitation coil terminal 413, the insulating sleeve 407 is connected to the permanent magnet mechanism panel 409 and the vacuum circuit breaker housing, the permanent magnet operating mechanism 412 and the permanent magnet mechanism housing are connected to the permanent magnet mechanism panel 409, the closed position sensor 410 and the open position sensor 411 are opposite to the permanent magnet mechanism action connecting rod 408, and the closed position sensor 410 and the open position sensor 411 are connected to the position sensor terminal 414.
[0031] When assembling the sleeve-type permanent magnet vacuum circuit breaker, the permanent magnet mechanism is located at the upper part, and the vacuum circuit breaker switch body 402 and the emergence terminal 401 are embedded in the transformer box 300.
[0032] When it is necessary to supply power to the electric power supply line, the external permanent magnet mechanism excitation power supply 415 inputs a "closing" pulse power supply to the permanent magnet mechanism excitation coil terminal 413, so that the permanent magnet operating mechanism 412 moves upward, and the permanent magnet mechanism action connecting rod 408 pushes the insulating connecting rod 406 upward, and the moving contact in the vacuum circuit breaker switch body 402 moves upward and closes with the static contact in the vacuum circuit breaker switch body 402, so that the power supply line power supply inlet terminal is connected with the power supply line power supply outlet terminal through the inlet terminal 405, the moving and static contacts in the vacuum circuit breaker switch body 402, the moving contact soft connecting piece 403, and the outlet terminal 401.

The permanent magnet mechanism action connecting rod 408 pulls the insulating connecting rod 406 and the moving contact connecting rod 404 of the vacuum circuit breaker switch body 402 downward, so that the moving contact located in the vacuum circuit breaker switch body 402 moves downward, so that the moving contact is separated from the static contact inside the vacuum circuit breaker switch body 402, disconnecting the connection between the power supply line power supply input terminal and the power supply line power supply output terminal, stopping the power supply to the power supply traction line, and completing the "open" switch operation.

[0034] In some optional embodiments, the bushing-type permanent magnetic vacuum circuit breaker 400 may also be integrated with at least one of the following components: a lightning arrester, a voltage transformer, and a current transformer.
[0035] like Figure 3-7 As shown, specifically, the embodiment of the present invention also discloses a specific structure of a disconnector, which includes: a base frame 501, two insulating pillars 502, a contact 503 (503'), a contact blade 504, an insulating door cover 505, a first transmission rod 506, a second transmission rod 507, a connecting rod 508, a rotating shaft 509 and an operating handle 510. The two insulating pillars 502 are respectively arranged on the base frame 501, and the contacts include a static contact 503' and a moving contact 503, and the static contact 503' and the moving contact 503 are respectively arranged on the top of the two insulating pillars 502, and the contact blade 504 is mounted on the static contact 503' and the moving contact 503, and is connected to the static contact 503' through a rotating shaft, and forms an openable and closable structure with the moving contact 503. The insulating door cover 505 is an openable and closable structure, which is sleeved on the outside of the moving contact 53, and can form an isolation blockage for the moving contact 503 or expose the moving contact 503, so as to facilitate the closed connection with the contact blade 504. An axial hole is opened on the side of the base frame 501, and the rotating shaft 509 is assembled in the axial hole. The rotating shaft 509 and the contact blade 504 are connected and linked by the connecting rod 508 and the first transmission rod 506. The rotating shaft 509 and the insulating door cover 505 are connected and linked by the connecting rod 508 and the second transmission rod 507. The operating handle 510 is connected to the rotating shaft 509 for operator control.
[0036] The insulating door frame 505 is composed of a first kit 5051 and a second kit 5052 to form a cylindrical opening and closing structure. The adjacent ends of the first kit 5051 and the second kit 5052 are respectively provided with a first rotating shaft 5053 and a second rotating shaft 5054. The first kit 5051 is tightly connected to the first rotating shaft 5053, and the second kit 5052 is tightly connected to the second rotating shaft 5054, so that the first kit 5051 and the second kit 5052 can be driven by the first rotating shaft 5053 and the second rotating shaft 5053 respectively and rotate along the first rotating shaft 5053 and the second rotating shaft 5054 as the center, thereby realizing the opening and closing of the other ends of the two; the opposing surfaces of the first kit 5051 and the second kit 5052 are groove structures corresponding to the outer shape structure of the moving contact 503, thereby forming a space for accommodating the moving contact 503 in the closed state. The first rotating shaft 5053 and the second rotating shaft 5054 are mounted on the base frame 501, and the first rotating wheel 5056 and the second rotating wheel 5057 cooperating with the sliding screw 5055 are respectively provided at the bottom of the base frame 501; the sliding screw 5055 is arranged between the first rotating wheel 5056 and the second rotating wheel 5057, and the sliding screw 5055 is engaged with the first rotating wheel 5056 and the second rotating wheel 5057 by friction or thread, and during the process of the sliding screw 5055 linearly displacing between the first rotating wheel 5056 and the second rotating wheel 5057, the two rotating wheels are driven to rotate, so that the two sets of the insulating door frame 505 are opened or closed; the other end of the sliding screw 5055 away from the rotating wheel is connected to the connecting rod 508. The sliding screw 5055 moves along the bottom surface of the base frame 501 through the sliding groove.
[0037] When the contact blade 504 and the moving contact 503 are in a closed state, the insulating door cover 505 is in an open state, exposing the moving contact 503. When the operator needs to open the contact blade 504, the operating handle 510 is used to rotate the rotating shaft 509, and then the rotating shaft 509 drives the connecting rod 508 to rotate, and then the connecting rod 508 drives the first transmission rod 506 to push the contact blade 504 away, so that the contact blade 504 and the moving contact 503 are separated and disconnected from the contact state. At the same time, the connecting rod 508 drives the second transmission rod 507 to push the insulating door cover 505 from the open state to gradually close, thereby forming an isolation blockade for the moving contact 503.
[0038] In some embodiments, the first kit 5051 and the second kit 5052 of the insulating door frame 505 can use hard insulating materials or flexible insulating materials. Preferably, the first kit 5051 and the second kit 5052 use insulating rubber with a thickness of not less than 5 cm. By selecting flexible insulators, the risks brought by rigid gaps can be reduced. At the same time, the thickness of 5 cm can effectively ensure the safety of sealing.
[0039] Specifically, the connection structure of the isolating switch 500 is as follows: the static contact 503 ′ of the isolating switch 500 is connected to the incoming line terminal 405 of the bushing type permanent magnetic vacuum circuit breaker 400 , and the moving contact 503 of the isolating switch 500 is connected to the incoming line cable 700 .
[0040] The isolating switch in the embodiment of the present invention can directly isolate and block the moving contact through the insulating door body when the contact blade is disconnected, thereby improving the safety factor of the operator and ensuring the personal safety of the operator.

[0042] like Figure 7 As shown, Figure 7 : is a schematic diagram of the structure of the first transmission rod of the three-phase isolating switch in the embodiment of the present invention; further, the first transmission rod 506 and the contact knife 504 in each phase of the isolating switch of the three-phase integrated structure are connected to the rotating shaft through the contact knife connection hole 511; wherein, the size of the contact knife connection hole 511 of each phase isolating switch is different, specifically, along the axial direction of the rotating shaft 509, the length of the contact knife connection hole 511 of the isolating switch gradually increases / decreases, thereby realizing the opening and closing of each phase isolating switch in the isolating switch of the three-phase integrated structure one by one. When in use, the operating handle 510 is rotated to drive the rotating shaft 509 to rotate, the rotating shaft 509 drives the connecting rod 508 to rotate, and the connecting rod 508 drives the first transmission rod 506 to move, so that the three phases A, B, and C are opened in sequence, and vice versa, the three phases A, B, and C can be closed in sequence.
