Technical Field

[0001] This utility model relates to the field of overvoltage protection technology, specifically to a surge arrester installation structure with a gap for overvoltage protection. Background Technology

[0002] Overvoltage protectors are electrical devices used in power engineering to protect overhead lines. They are mainly used to prevent accidents such as insulator flashover and conductor melting caused by direct lightning overvoltage or induced overvoltage. They achieve line protection by guiding lightning current and cutting off the power frequency follow current. The overvoltage protector is arranged parallel to the insulator, and the series gap parameters must be matched according to the insulator type during installation. However, this installation has the following technical drawback: when there is an angle between the protector body and the insulator, the existing connection support plate cannot meet the installation requirements.

[0003] Therefore, how to design a surge arrester installation structure with a gap for overvoltage protection has become an urgent problem to be solved. Utility Model Content

[0005] The technical solution of this utility model is: a surge arrester installation structure for overvoltage protection with a gap, including a surge arrester body, the surge arrester body being arranged at an angle, one end of the surge arrester body being installed on an overhead insulated conductor in sequence through a small insulating cover, a surge arrester lead wire, and an Ampere clamp; the other end of the surge arrester body is a first threaded section, the first threaded section being locked in sequence through a first spring washer and a first nut after passing through one end of an anti-derailment mounting plate, the other end of the anti-derailment mounting plate being located between an insulator and a mounting frame, the threaded section of the insulator being locked in sequence through a second spring washer and a second nut after protruding from the mounting frame; a surge arrester is provided between the middle part of the surge arrester body and the end near the small insulating cover, the surge arrester gap distance being 40mm±5mm.

[0006] This utility model uses an anti-detachment mounting plate at one end to fix the other end of the inclined protector body, and the other end of the anti-detachment mounting plate to fix the insulator and mounting bracket. One end of the protector body is installed on the overhead insulated conductor in sequence through a small insulating cover, the protector upper lead wire, and an Ampere clamp, thus completing the installation when there is an angle between the protector body and the insulator, and solving the technical defect that the existing connecting support plate cannot meet the installation requirements.

[0007] Preferably, the anti-detachment mounting plate has a "7" shaped structure with an obtuse angle. The horizontal plate of the "7" shaped structure has irregular holes, including a first waist-shaped hole. One end of the first waist-shaped hole has an opening groove with a width of 21mm. The opening groove has an angle of 60° with the edge of the "7" shaped structure. The length direction of the first waist-shaped hole is arranged along the length direction of the "7" shaped structure.

[0008] This utility model adopts a "7"-shaped anti-detachment mounting plate. The horizontal plate of the "7"-shaped structure is provided with irregular holes, including a first waist-shaped hole. One end of the first waist-shaped hole is provided with an opening groove. The opening groove and the edge of the "7"-shaped structure have an angle of 60°.

[0014] See Figure 1-3 The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore lack substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention.

[0015] Example 1: A surge arrester mounting structure for overvoltage protection with a gap, referenced. Figure 1 , Figure 2 The device includes a protector body 1, which is arranged at an angle. One end of the protector body 1 is installed on the overhead insulated conductor 5 via a small insulating cover 2, a protector upper lead wire 3, and an Ampere clamp 4. The other end of the protector body 1 is a first threaded section. The first threaded section passes through one end of an anti-derailment mounting plate 7 and is then locked by a first spring washer and a first nut. The other end of the anti-derailment mounting plate 7 is located between an insulator 6 and a mounting frame 8. The threaded section of the insulator 6 protrudes from the mounting frame 8 and is then locked by a second spring washer and a second nut. A surge arrester is installed between the middle of the protector body 1 and the end closest to the small insulating cover 2. The surge arrester is located on the side away from the overhead insulated conductor 5, and the gap between the surge arresters is 40mm ± 5mm. This utility model uses an anti-detachment mounting plate at one end to fix the other end of the inclined protector body, and the other end of the anti-detachment mounting plate to fix the insulator and mounting bracket. One end of the protector body is installed on the overhead insulated conductor in sequence through a small insulating cover, the protector upper lead wire, and an Ampere clamp, thus completing the installation when there is an angle between the protector body and the insulator, and solving the technical defect that the existing connecting support plate cannot meet the installation requirements.

[0016] Example 2: Based on Example 1, the anti-detachment mounting plate 7 has a "7"-shaped structure with an obtuse angle. A shaped hole 701 is provided on the horizontal plate of the "7"-shaped structure. The shaped hole 701 includes a first oblong hole, one end of which has an opening groove with a width of 21mm. The opening groove forms a 60° angle with the edge of the "7"-shaped structure. The length of the first oblong hole is arranged along the length of the "7"-shaped structure. This utility model uses a "7"-shaped anti-detachment mounting plate with a shaped hole on the horizontal plate. The shaped hole includes a first oblong hole, one end of which has an opening groove. The opening groove forms a 60° angle with the edge of the "7"-shaped structure. The hook formed by the opening groove and the first oblong hole prevents the anti-detachment mounting plate from detaching from the insulator.

[0017] Example 3: Based on Example 2, the inclined plate of the "7"-shaped structure is provided with a first through hole 702 at its center, which is used for the passage of the first threaded section. This utility model uses a first through hole at the center of the inclined plate of the "7"-shaped structure, which is used for the passage of the first threaded section. After passing through the anti-detachment inclined mounting plate, the first threaded section is locked in place by the first spring washer and the first nut.

[0018] Example 4: Based on Example 2, symmetrically arranged second oblong holes 703 are provided at the corners of the "7"-shaped structure, with the length direction of the second oblong holes 703 along the length direction of the "7"-shaped structure. This utility model employs symmetrically arranged second oblong holes at the corners of the "7"-shaped structure. These second oblong holes are countersunk holes, which can be used to reduce the weight of the anti-detachment inclined mounting plate.

[0019] Example 5: Based on Example 2, a reinforcing rib 704 is provided inside the corner of the "7"-shaped structure. The thickness of the reinforcing rib 704 is 1.5mm, and the reinforcing rib 704 has a V-shaped structure. The included angle between the V-shaped structure and the "7"-shaped structure is 120°. This utility model uses a reinforcing rib inside the corner of the "7"-shaped structure, which can enhance the structural strength of the anti-detachment inclined mounting plate.

[0020] The above-described embodiments are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
