[0015] A method for using an operation and maintenance operation system of a power distribution automation terminal box specifically includes the following steps: S1: During the operation and maintenance of the distribution automation terminal box body, first open the operation box and control the control host through the control panel. Use the camera to capture the internal picture of the distribution automation terminal box body and display it through the control host. When it is necessary to detect a certain wire body inside the distribution automation terminal box body, the electric push rod extends to make the clamping part snap into the clamping groove. When the installation cylinder cannot rotate, control the first servo motor to drive the guide rod with a threaded groove to rotate. Through the engagement of the guide rod with a threaded groove and the internal threaded hole of the installation cylinder, the sliding frame slides up and down inside the distribution automation terminal box body. The third servo motor can be used to control the rotation of the rotating shaft, thereby controlling the rotation of the gear part. By controlling the rotation of the gear part, the gear part meshes with the rack to adjust the position of the moving frame on the side wall of the sliding frame. The fourth servo motor can be used to control the rotation of the second threaded rod, thereby adjusting the position of the movable frame on one side of the moving frame, so that the current transformer core inside the movable frame can better clamp and detect the wire body; S2: Adjust to move the current transformer core to one side of the wire body to be detected. The fifth servo motor can be used to control the rotation of the installation shaft. By rotating the installation shaft, it can be used to control the rotation of one of the current transformer cores. When one of the current transformer cores rotates, it can drive the other current transformer core to rotate in the opposite direction simultaneously through the teeth and grooves, thereby realizing the clamping of the two current transformer cores, making the wire body located on one side of the secondary winding of the current transformer inside the current transformer core. If the ammeter reading is zero, it indicates that there is no leakage in the line. If the ammeter reading is not zero, it means that there is a leakage phenomenon in the circuit. The wireless connection module is connected to the wireless connector. By setting the wireless connection module, the ammeter can be connected to the central processor in the control host through the wireless connector, so that the detection data can be transmitted to the control host, and the detection situation can be directly observed; S3: When the wire body has problems and needs to be repaired, open the movable door. When the movable door is opened, the first limit block will first contact the second limit block inside the movable groove and push the second limit block into the movable cavity. Then, the second limit block pops out under the support of the support spring and catches the first limit block in the movable groove, making the movable door unable to close, fixing the position of the movable door after it is opened, and preventing the movable door from rotating randomly after it is opened, which affects the operation of the operator.

[0016] The present invention has at least the following beneficial effects: (1) In this solution, by setting up an operation and maintenance mechanism and a remote control mechanism, during the operation and maintenance process, the operation and maintenance personnel operate the operation and maintenance mechanism through the control host, observe the internal situation of the distribution automation terminal box body through the camera, rotate the guide rod to make the sliding frame slide up and down inside the distribution automation terminal box body, then rotate the gear part to make the movable frame move horizontally inside the distribution automation terminal box body, and then rotate the second threaded rod to adjust the distance between the movable frame and the moving frame, so as to adjust the distance between the transformer core and the wire body inside the distribution automation terminal box body, enabling the transformer core to clamp and detect the wire body inside the distribution automation terminal box body more accurately. During the detection process, it is not necessary to open the distribution automation terminal box body, making the entire operation and maintenance detection process more time-saving and labor-saving, and making the operation and maintenance more convenient and fast. (2) In this solution, by setting up a clamping mechanism, when the movable door is opened, the first limit block will first come into contact with the second limit block inside the movable groove, push the second limit block into the movable cavity, and then the second limit block pops out under the support of the support spring, clamping the first limit block in the movable groove to fix the position of the movable door after it is opened, preventing the movable door from rotating randomly after it is opened and affecting the operation of the operator. (3) In this solution, the electric push rod can be used to control the movement of the clamping part. By moving the clamping part, it can be inserted into the clamping groove to control the rotation of the installation cylinder. When the installation cylinder cannot rotate, the guide rod with a threaded groove rotates to drive the sliding frame to move. When the installation cylinder can rotate, the sliding frame can quickly move to the bottom of the guide rod and quickly move to the bottom end inside the distribution automation terminal box body to achieve the effect of quick reset. (4) In this solution, the second servo motor can be used to control the rotation of the first threaded rod. By rotating the first threaded rod, it can be used to control the movement of the slider inside the adjustment groove, thereby controlling the position of the camera and making the observation more comprehensive.

The third servo motor 311 can be used to control the rotation of the rotating shaft 313, thereby controlling the rotation of the gear member 314. By controlling the rotation of the gear member 314, the gear member 314 can be engaged with the rack 301 to adjust the position of the moving frame 31 on the side wall of the sliding frame 3. The fourth servo motor 312 can be used to control the rotation of the second threaded rod 315, thereby adjusting the position of the movable frame 32 on one side of the moving frame 31, so that the current transformer core 33 inside the movable frame 32 can better clamp and detect the wire. By adjusting, the current transformer core 33 is moved to one side of the wire to be detected. The fifth servo motor 321 can be used to control the rotation of the mounting shaft 333. By rotating the mounting shaft 333, it can be used to control the rotation of one of the current transformer cores 33. When one of the current transformer cores 33 rotates, it can drive the other current transformer core 33 to rotate in the opposite direction simultaneously through the teeth 334 and the tooth grooves 335, thereby realizing the clamping of the two current transformer cores 33, and making the wire located on one side of the secondary winding 336 of the current transformer inside the current transformer core 33. If the reading of the ammeter 331 is zero, it indicates that there is no leakage in the circuit. If the reading of the ammeter 331 is not zero, it means that there is a leakage phenomenon in the circuit. The wireless connection module 332 is connected to the wireless connector 203. By setting the wireless connection module 332, the ammeter 331 can be connected to the central processing unit 205 in the control host 201 through the wireless connector 203, so that the detection data can be transmitted to the control host 201, and thus the detection situation can be directly observed. When the wire has problems and needs to be repaired, open the movable door 101. When the movable door 101 is opened, the first limit block 1011 will first contact the second limit block 106 inside the movable groove 102 and push the second limit block 106 into the movable cavity 103. Then, the second limit block 106 pops out under the support of the support spring 105 and catches the first limit block 1011 in the movable groove 102, making the movable door 101 unable to close, fixing the position of the movable door 101 after it is opened, and preventing the movable door 101 from rotating randomly after it is opened, which affects the operation of the operator.
