Description

Technical Field

[0001] This utility model relates to the field of surge arrester monitoring technology, specifically a fixed structure that facilitates the quick installation and disassembly of surge arrester monitoring devices. Background Technology

[0002] Surge arresters are crucial overvoltage protection devices in power systems, and their performance directly affects the stability and safe operation of the power grid. To monitor the health status of surge arresters in real time, especially their leakage current and number of trips, online surge arrester monitoring devices (or monitors) are widely installed in the grounding down conductor circuit of surge arresters.

[0003] Most current inspection devices rely on multiple sets of bolts for installation. Both installation and disassembly require repeated operations by staff, which reduces installation efficiency and, over time, causes the bolts to rust together, making maintenance and disassembly difficult.

A connecting frame is connected to one side of the mounting plate, and a back plate is connected to the other side of the connecting frame. A ring is connected to one side of the back plate, and a rotating frame is rotatably mounted on the surface of the ring. A pipe frame is connected to the back of the rotating frame, and a positioning pin is slidably mounted at one end of the pipe frame. A traction spring is connected between the positioning pin and the back plate. A rotating shell is rotatably mounted on one side of the back plate, and a torsion frame is connected to one side of the rotating shell. A movable clip is slidably mounted inside the rotating shell, and a spring is connected to the bottom of the inner side of the rotating shell. A sliding hole is opened on one side of the mounting plate, and a movable component is slidably mounted in the sliding hole. A fixed base is connected to one side of the mounting plate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: including a mounting plate 1 and an online monitoring instrument 111 for installation. A connecting frame 2 is connected to one side of the mounting plate 1, and a back plate 3 is connected to the other side of the connecting frame 2. A ring 4 is connected to one side of the back plate 3, and a rotating frame 5 is rotatably mounted on the surface of the ring 4. A pipe frame is connected to the back side of the rotating frame 5, and a positioning pin 7 is slidably mounted at one end of the pipe frame. A traction spring 6 is connected between the positioning pin 7 and the back plate 3. A rotating shell 8 is rotatably mounted on one side of the back plate 3, and a torsion frame 9 is connected to one side of the rotating shell 8. A movable clip 10 is slidably mounted inside the rotating shell 8, and a spring piece 12 is connected to the bottom inside the rotating shell 8. The top of the spring piece 12 abuts against the movable clip 10, and a sliding hole 15 is opened on one side of the mounting plate 1. A movable component 17 is slidably mounted in the sliding hole 15. A fixed seat 16 is connected to one side of the mounting plate 1.

[0021] Reference Figure 2 As shown, a connecting bolt 18 is provided on one side of the mounting plate 1 and the back of the positioning pin 7. A nut 19 is provided on one end of each connecting bolt 18. When installing the grounding wire, one end of the grounding wire can be sleeved on the connecting bolt 18 at one end of the positioning pin 7, and the other end can be sleeved on the connecting bolt 18 on one side of the mounting plate 1. The connection and fixation are made by using the nut 19, which is convenient.

[0022] Reference Figure 3 As shown, the movable card 10 has a sliding groove 14 on both sides. A limit card head 13 is connected to the inner side of the rotating shell 8 corresponding to the sliding groove 14. The connection between the limit card head 13 and the sliding groove 14 effectively limits the range of movement of the movable card 10 inside the rotating shell 8, ensuring stability.

[0023] Reference Figure 4As shown, the movable component 17 includes a rectangular frame 172 slidably disposed inside the sliding hole 15. A movable seat 171 is connected to one side of the rectangular frame 172, and a movable groove 175 is opened on one side of the movable seat 171. A bolt 173 is connected to the other side of the rectangular frame 172, and a handwheel 174 is connected to the other end of the bolt 173. The fixed seat 16 has the same structure as the movable seat 171. The current sensor or induction coil is clamped to the fixed seat 16 and the movable seat 171 through the mounting holes at both ends for the lightning arrester to pass through and for monitoring overcurrent. The position of the movable seat 171 can be adjusted by sliding the rectangular frame 172 along the sliding hole 15. After the adjustment is complete, the handwheel 174 is rotated, and the rectangular frame 172 is positioned and fixed at a certain point in the sliding hole 15 through the connection between the bolt 173 and the rectangular frame 172. This makes it suitable for the installation of current sensors or induction coils of different sizes.

[0024] Reference Figure 3 As shown, a corresponding fitting groove is provided on one side of the rotating frame 5 corresponding to the online monitoring instrument 111. One end of the positioning pin 7 passes through the back plate 3 and is inserted into the online monitoring instrument 111. During installation, the movable card 10 is pulled down by the online monitoring instrument 11, and then the bottom end of the online monitoring instrument 111 is inserted into the fitting groove. The movable card 10 is released, and the spring piece 12 pushes the movable card 10 upward to lock the online monitoring instrument 111. With the help of the positioning pin 7, the online monitoring instrument 111 is fixed between the movable card 10 and the back plate 3. The movable card 10 is slidably connected to the ring 4, and a toggle frame 11 is provided on one side to facilitate the toggle of the movable card 10.

[0025] The implementation principle of this application is as follows: When using this utility model, firstly, the movable card 10 is pushed down by the actuating frame 11 to expose the fitting groove on one side of the rotating frame 5. Then, the bottom end of the online monitoring instrument 111 is inserted into the fitting groove. Then, the actuating frame 11 is released, and the spring piece 12 pushes the movable card 10 back to its original position through its own elasticity, thereby blocking the fitting groove. At the same time, the slot at the top of the movable card 10 will lock the bottom surface of the online monitoring instrument 111. Then, the rotating housing 8 is rotated by the torsion frame 9, which drives the rotating frame 5 and the online monitoring instrument 111 to rotate until the mounting hole below the online monitoring instrument 111 aligns with the back plate 3. When the holes are aligned, the elasticity of the traction spring 6 will pull the positioning pin 7 to reset, pass through the rotating frame 5, and insert it into the mounting hole below the online monitoring instrument 111, thereby completing the fixed installation of the online monitoring instrument 111. Adjust the position of the movable component 17, install the induction coil or current sensor between the fixed base 16 and the movable component 17, and then connect the grounding wire to one end of the positioning pin 7 and the connecting bolt 18 on one side of the mounting plate 1. Use the nut 19 to fix the terminal on the grounding wire to the connecting bolt 18, and then pass the lightning arrester lower wire through the induction coil or current sensor and connect it to the online monitoring instrument 111.
