Description

Technical Field

[0001] The present invention relates to the technical field of overvoltage protection devices, in particular to a segmented corner lightning protection overvoltage protection component. Background Art

[0002] Overvoltage protection devices are used to protect lines and equipment from overvoltages caused by lightning currents, induced currents, or switching overvoltages. When there is no overvoltage in the line, the overvoltage protection device is in a high-impedance or open-circuit state, thus not affecting normal line operation. When overvoltage is caused by lightning currents or operating equipment, the overvoltage protection device switches to a conducting state, dissipating the lightning current and controlling the voltage to a reasonable level, thereby protecting the safety of equipment and lines.

[0003] Segmented corner lightning overvoltage protection components can be installed at line corners or segment points to protect the line from lightning overvoltage. When subjected to lightning current or voltage, traditional equipment can only drain and discharge the current through a single grounding device, which can easily increase the load on the protection device and cause damage. Summary of the Invention

The protection component can effectively disperse lightning overvoltage to different grounding paths, reduce the impact on a single grounding path, and thereby protect subsequent electrical equipment from damage by overvoltage.

[0006] Preferably, the protector is connected to at least one current sensor, and the protector, lightning arrester, current sensor, first connecting line, switch, ground wire, second connecting line, and disconnector are all electrically connected, and the current sensor, first connecting line, and switch are connected in parallel.

[0007] Preferably, a groove is provided at the top of the protector, and the groove, the first fixing cylinder and the inner wall of the second fixing cylinder are all in contact with the high-voltage circuit.

[0008] Preferably, a through hole is provided on the top surface of the connecting plate, and a sliding frame is slidably connected to the outer wall of the connecting plate. A accommodating hole is provided on the top and bottom surfaces of the sliding frame.

A mounting hole is provided on the rear side of the sliding frame, and a limiting column is slidably provided on the inner wall of the mounting hole. A limiting spring is wrapped around the outer wall of the limiting column, one end of the limiting spring is fixed to the inner wall of the mounting hole, and the other end of the limiting spring is fixed to the outer wall of the limiting column. A plurality of positioning slots are provided on the rear side of the connecting plate, and the positioning slots correspond to the mounting holes. The limiting column passes through the mounting hole and is slidably arranged with the positioning slots. By adjusting the sliding frame, the installation angle and position of the lightning arrester can be adjusted to cover a wider or more precise protection area.

[0009] Preferably, a sliding bar is fixed to the front side of the inner wall of the sliding frame, a sliding groove is opened on the front side of the connecting plate, the sliding bar is slidably connected to the sliding groove, and the sliding bar can limit the sliding frame to make the sliding frame more stable.

[0010] Preferably, two connecting holes are provided on one side of the mounting bracket, an arc-shaped plate is provided on the right side of the mounting bracket, two threaded rods are fixed on the left side of the arc-shaped plate, the threaded rods are slidably arranged with the connecting holes, and the outer walls of the threaded rods are threadedly connected to two nuts, and pressure can be applied to the mounting bracket by tightening the nuts, so that the mounting bracket can be more stably fixed on the fixed object.

[0011] Preferably, an anti-slip pad is fixed to the inner wall of the curved plate, which can increase the friction between the inner wall of the curved plate and the fixed object, preventing the mounting frame from sliding down after being fixed, thereby improving the stability of the mounting frame and the protective component, and further improving the working efficiency of the protective component.

[0012] Preferably, the first fixing tube is at the same height as the protector.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, the current sensor can monitor the current flowing through the first connecting line in real time. When the voltage on the line exceeds the rated discharge voltage of the arrester, the discharge gap will break down. The current sensor can quickly trigger the switch to conduct the overvoltage to the ground through the ground wire, thereby protecting the line and connected equipment from damage. The combination of the sliding frame and the limit column can facilitate the adjustment of the position of the arrester, so that the input end of the arrester can be connected in sections, thereby meeting different installation requirements and improving the adaptability of the arrester.

[0015] Second, the sliding bar and the sliding groove cooperate to limit the sliding frame, preventing it from shaking when sliding on the outer wall of the connecting plate, making the sliding frame and the lightning arrester more stable during movement, and preventing the sliding frame from falling due to excessive movement. The nut and the threaded rod cooperate to facilitate the staff to fix the mounting frame, allowing the staff to adjust the curved plate and threaded rod according to the diameter of the fixed object, thereby improving the flexibility of the mounting frame.

The protector 3, the lightning arrester 5, the current sensor 6, the first connecting line 7, the switch 8, the ground wire 9, the second connecting line 10, and the disconnector 11 are all electrically connected. The current sensor 6, the first connecting line 7, and the switch 8 are connected in parallel with each other.

The input end of the lightning arrester 5 can be connected to the first fixed cylinder 12 or the second fixed cylinder 13.

[0025] During use, current sensor 6 monitors the current flowing through first connecting line 7 in real time. When the voltage on the line exceeds the rated discharge voltage of arrester 5, the discharge gap breaks down, and current sensor 6 quickly triggers switch 8, directing the overvoltage to the ground via ground wire 9, thereby protecting the line and connected equipment from damage. The protective assembly effectively disperses lightning overvoltage across different grounding paths, reducing the impact on a single grounding path and protecting subsequent electrical equipment from overvoltage damage.

[0026] like Figure 1-Figure 3 and Figure 5As shown, a through hole 14 is provided on the top surface of the connecting plate 4, and a sliding frame 15 is slidably connected to the outer wall of the connecting plate 4. The top and bottom surfaces of the sliding frame 15 are provided with a receiving hole 16, and the lightning arrester 5 is fixed in the receiving hole 16.

This allows the operator to adjust curved plate 24 and threaded rod 25 according to the diameter of the object being fixed, thereby enhancing the flexibility of mounting frame 1. Anti-slip pad 27 increases the friction between the inner wall of curved plate 24 and the object being fixed, preventing mounting frame 1 from sliding down after being fixed.
