[0002] With rapid socio-economic development and continuously rising electricity demand, users are becoming increasingly sensitive to power outages. Existing disconnect switches demonstrate significant shortcomings in fault repair. In actual power grid operation, when a fault occurs and the disconnect switch needs to be switched to maintenance mode, rapid remote operation is not possible; manual operation by maintenance personnel on-site is mandatory, a process that is extremely time-consuming. This operating mode significantly extends maintenance time, increases the average power restoration time beyond expectations, and substantially increases the duration of power outages, severely impacting power supply reliability and causing considerable inconvenience to users' production and daily lives. It fails to effectively meet the needs of rapid power restoration and ensuring the safe and stable operation of the power grid, becoming a key obstacle to the construction of smart distribution networks. Therefore, this utility model provides an intelligent electric disconnect switch to solve the above problems. Summary of the Invention

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] like Figure 1-6 This utility model discloses an intelligent electric disconnect switch, which includes a U-shaped groove 2, insulator strings 3, a switching push-pull rod 4, a connecting conductor 5, a transmission assembly 1, a control box 10, a back-end management terminal 11, and a remote controller 12. The transmission assembly 1 is installed on the top of the U-shaped groove 2. There are two insulator strings 3, with the tops of the two insulator strings 3 respectively installed on the bottom of the left and right sides of the U-shaped groove 2. The top of the switching push-pull rod 4 is hinged to the transmission assembly 1, and the bottom middle position of the connecting conductor 5 is connected to the switching push-pull rod. The bottom of the gate push-pull rod 4 is hinged, and one end of the connecting conductor 5 is hinged to the bottom of the insulator string 3 on the left side of the U-shaped groove 2, and the other end is movably connected to the bottom of the insulator string 3 on the right side of the U-shaped groove 2. A controller and a wireless communication module connected to the controller are installed inside the control box 10. The transmission assembly 1 is electrically connected to the controller inside the control box 10. The background management terminal 11 and the remote controller 12 are wirelessly connected to the controller inside the control box 10. The transmission assembly 1 includes a housing 13, a motor 14, a rotating shaft 15, a gear 16, and a chain 17. The housing 13 is installed on the top of the U-shaped groove 2, and the motor 14 is installed on the outside of the housing 13. Two rotating shafts 15 are rotatably installed from top to bottom inside the housing 13, and the rotating shaft 15 located at the upper position rotates through the housing 13 and is connected to the output shaft of the motor 14. A gear 16 is installed on the rotating shaft 15, and a chain 17 is meshed on the gear 16. A connecting rod 18 is installed on one side of the chain 17, and one end of the connecting rod 18 is hinged to the top of the opening and closing push-pull rod 4. The motor 14 is electrically connected to the controller in the control box 10. Both the back-end management terminal and the remote controller are equipped with ground wireless communication modules that connect to the wireless communication module inside the control box. When the electric control system is controlling the opening and closing of the circuit breaker, control information is sent to the controller remotely through the back-end management terminal or on-site through the remote controller. The controller then controls the motor to perform the opening and closing operations. When the motor rotates forward, the opening and closing push-pull rod pulls the connecting conductor upward, and the other end of the connecting conductor contacts the bottom of the insulator string on the right side of the U-shaped groove, thus achieving the closing operation. When the motor rotates in reverse, the opening and closing push-pull rod pushes the connecting conductor downward, thus achieving the opening operation.

[0018] The bottom of the connecting conductor 5 is also equipped with a manual pull ring 6; the manual pull ring is an insulated pull ring, and the motor will automatically unlock when the motor fails. At this time, the circuit breaker can be manually opened and closed. Pulling the manual pull ring will drive the opening and closing push rod to run. The circuit breaker will be opened by moving downward and closed by moving upward.

[0019] Work process:

[0020] The working principle of this utility model is as follows: Three electric disconnect switches are combined into an electric disconnect switch group 8. Before use, the electric disconnect switch group 8 is installed on the pole 7 at an appropriate position and connected to the controller in the control box 10 via the connecting wire 9. The electric disconnect switches can be remotely operated or remotely controlled on-site. When the electric control is used for opening and closing, the controller is sent remotely through the background management terminal 11 or on-site through the remote controller 12. The controller controls the motor 14 to perform the opening and closing operation. When the motor 14 rotates forward, the opening and closing push-pull rod 4 pulls the connecting conductor 5 upward. The other end of the connecting conductor 5 contacts the bottom of the insulator string 3 on the right side of the U-shaped groove, realizing the closing operation. When the motor 14 rotates in reverse, the opening and closing push-pull rod 4 pushes the connecting conductor 5 downward, realizing the opening operation.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
