[0002] The common distribution switch monitoring terminal, referred to as FTU, has functions such as remote control, telemetry, telesignaling, and fault detection. It communicates with the distribution automation master station to provide the distribution system operation status and various parameters and information required for monitoring and control, including switch status, power parameters, phase faults, ground faults, and parameters at the time of fault. It also executes commands issued by the distribution master station to adjust and control the distribution equipment, and realize functions such as fault location, fault isolation, and rapid power restoration in non-fault areas.

[0003] Distribution switch monitoring terminals, typically installed near feeder switches, are specifically designed to monitor the status and operating data of outdoor pole-mounted switches, such as circuit breakers, load switches, and section switches on 10kV lines. Integrating multiple functions, including telemetry, telesignaling, remote control, protection, and communication, these terminals are a core component of feeder automation systems. Connected to the master station system via high-speed industrial network communication technology, these terminals can report switch status, fault information, and other data in real time. They also receive and execute control commands from the master station, enabling automatic identification and isolation of feeder faults and rapid restoration of power to non-faulty areas, thereby improving the reliability and automation of the distribution network.

[0004] The functional characteristics of the distribution switch monitoring terminal determine that its operation and maintenance frequency will be much higher than that of conventional switch products. However, existing distribution switch monitoring terminal products have problems such as insufficient operating space and inconvenient maintenance. They cannot meet the needs of simultaneous maintenance of multiple protection modules. In addition, they have many parts and a complex structure, making assembly and debugging difficult. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a withdrawable distribution switch monitoring terminal with a simple structure, fewer parts, convenient maintenance of the protection module and high maintenance efficiency.

[0006] In order to solve the above technical problems, this application provides the following technical solutions:

[0007] The present invention provides a pull-out distribution switch monitoring terminal, including an installation frame, a door body, a door body frame, a door body frame connecting plate, and a protection module. One side of the door body is hinged to the door body frame, and a door lock is provided between the other side of the door body and the door body frame. The door body frame connecting plate is connected to the door body frame, and the door body frame connecting plate is suitable for moving relative to the installation frame so that the door body frame is located inside the installation frame or moved outside the installation frame. The protection module is arranged in the door body, and the protection module is connected to a cable. The cable connected to the protection module moves synchronously with the door body frame connecting plate relative to the installation frame.

[0008] Furthermore, it also includes a tank chain, one end of which is connected to the mounting frame and the other end is connected to the door frame connecting plate, and the cable of the protection module is connected to the tank chain.

[0009] Furthermore, it also includes at least one guide rail group, and different guide rail groups are arranged in sequence along the height direction of the mounting frame. Each guide rail group includes two guide rails, and the two guide rails are respectively connected to the left and right sides of the mounting frame. The door frame connecting plate is provided with at least one group, and the door frame connecting plate and the guide rail correspond one to one. The door frame connecting plate is a flat plate, and a slider is provided on the door frame connecting plate. When the door frame connecting plate moves relative to the mounting frame, the slider slides on the guide rail.

[0010] Furthermore, there are two groups of the guide rail groups and the door frame connecting plates, the two groups of the guide rail groups are respectively arranged at the two ends of the installation frame along the height direction, and the two groups of the door frame connecting plates are respectively connected to the two ends of the door frame along the height direction.

[0011] Furthermore, it also includes a tank chain fixed mounting frame and a tank chain movable mounting frame, the tank chain fixed mounting frame is connected to the mounting frame, the tank chain movable mounting frame is connected to the slider, one end of the tank chain is connected to the tank chain fixed mounting frame, and the other end is connected to the tank chain movable mounting frame.

[0012] Furthermore, the tank chain fixed mounting frame and the tank chain movable mounting frame are both made of profiles.

[0013] Furthermore, the installation frame is formed by welding angle steels.

[0014] Compared with the prior art, the withdrawable distribution switch monitoring terminal of the present invention has at least the following beneficial effects:

[0015] The present invention provides a pull-out distribution switch monitoring terminal. Since one side of the door body is hinged on the door body frame, the door body frame connecting plate is connected to the door body frame, and the door body frame connecting plate is suitable for moving relative to the installation frame so that the door body frame is located inside the installation frame or moved outside the installation frame, the door body can be rotated after the door body and the door body frame are moved outside the installation frame, overcoming the limitation of width space on the door body rotation operation. After the door body is rotated, the manual operation space and operation freedom are greatly improved, which is convenient for maintenance and repair of the protection module.
