[0002] An arrester is an electrical appliance used to protect electrical equipment from high transient overvoltages and limit the follow current time and often limit the follow current value. This term includes any external gap necessary for the normal function of the electrical appliance during operation and installation, regardless of whether it is a component of the whole. An AC gapless metal oxide arrester is used to protect the insulation of AC power transmission and transformation equipment from lightning overvoltages and switching overvoltages, and is applicable to overvoltage protection of transformers, transmission lines, distribution panels, switch cabinets, power metering boxes, vacuum switches, shunt compensation capacitors, rotating motors, semiconductor devices, etc. Arresters are divided into many types, including metal oxide arresters, line-type metal oxide arresters, gapless line-type metal oxide arresters, fully insulated composite jacket metal oxide arresters, removable arresters. The main types of arresters include tubular arresters, valve-type arresters, zinc oxide arresters, etc. The main working principles of each type of arrester are different, but their working essence is the same, which is to protect communication cables and communication equipment from damage;

[0003] Traditional arresters have some disadvantages. The installation structure of the arrester is relatively simple. Generally, it is installed on the installation surface through bolts and brackets, which results in insufficient installation firmness. It cannot lock the arrester on the bracket well, and the installation firmness is not good enough, and it is easy to loosen and fall, resulting in arrester damage. Content of the Utility Model

[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0021] As Figures 1-4 shown, a surge arrester convenient for installation includes an installation base 1 and a surge arrester main body 3. An installation mechanism 4 is arranged at one end of the installation base 1. The installation mechanism 4 includes a fixed frame 41 fixedly connected to one end of the installation base 1. A connecting rod 42 is movably connected inside the fixed frame 41. An internal thread ring 43 is threadedly connected to the outer side of the connecting rod 42 near the upper side of the fixed frame 41. A limiting ring 44 is fixedly connected to the outer side of the connecting rod 42 near the lower side of the fixed frame 41. The lower end of the connecting rod 42 is fixedly connected to a docking frame 45. A positioning groove 46 is opened at one end of the docking frame 45. A threaded rod 47 is threadedly connected inside the docking frame 45. A sliding rod 48 is slidably connected inside the docking frame 45 near the front side of the threaded rod 47. The lower end of the sliding rod 48 is fixedly connected to a clamping strip 49. A limiting piece 410 is movably connected inside the clamping strip 49.

[0022] In this embodiment, a limiting block 411 is fixedly connected to the upper end of the sliding rod 48. The lower end of the internal thread ring 43 is in contact with the upper end of the fixed frame 41. The upper end of the limiting ring 44 is movably connected to the lower end of the fixed frame 41. The central axes of the connecting rod 42, the internal thread ring 43 and the limiting ring 44 are located on the same straight line. The threaded rod 47 extends into the clamping strip 49. The threaded rod 47 is movably connected to the clamping strip 49. The upper end of the limiting piece 410 is fixedly connected to the lower end of the threaded rod 47. The number of the threaded rod 47, the sliding rod 48, the clamping strip 49, the limiting piece 410 and the limiting block 411 is two groups.

[0023] Specifically, the connecting rod 42 is clamped outside the wire bracket, so that the docking frame 45 wraps around the wire bracket. Then, the threaded rod 47 is rotated, causing the threaded rod 47 to push the clamping strip 49 downward through the limiting piece 410, and the clamping strip 49 drives the sliding rod 48 to slide downward. As a result, the clamping strip 49 contacts the wire bracket, thus limiting the docking frame 45 outside the wire bracket. Since the docking frame 45 wraps around the wire bracket, the clamping strip 49 can better limit the docking frame 45 on the wire bracket. And because the clamping strip 49 is strip-shaped, the contact area between the clamping strip 49 and the wire bracket is greatly increased, improving the stability of the docking frame 45 limited on the wire bracket. By clamping the docking frame 45 outside the wire bracket and then rotating the threaded rod 47 to make the threaded rod 47 push the clamping strip 49 downward through the limiting piece 410 so that the clamping strip 49 contacts the wire bracket, the purpose of facilitating the clamping strip 49 to limit the docking frame 45 outside the wire bracket can be achieved. Since the docking frame 45 wraps around the wire bracket, the clamping strip 49 can better limit the docking frame 45 on the wire bracket. And because the clamping strip 49 is strip-shaped, the contact area between the clamping strip 49 and the wire bracket is greatly increased, improving the stability of the docking frame 45 limited on the wire bracket.

[0024] In this embodiment, the other end of the mounting base 1 is fixedly connected to a connecting ring 2. The lightning arrester main body 3 is installed inside the connecting ring 2. The mounting base 1, the connecting ring 2, the lightning arrester main body 3, and the mounting mechanism 4 form an L shape.

[0025] Specifically, through the action of the mounting mechanism 4, the purpose of facilitating the installation of the lightning arrester main body 3 on the wire bracket can be achieved.

[0026] Working principle:

[0027] In use, the worker first loosens the internal-threaded ring 43, then rotates the docking frame 45, causing the docking frame 45 to rotate about the connecting rod 42 as an axis, adjusts the docking frame 45 to match the angle of the wire bracket, then tightens the internal-threaded ring 43. Further, the internal-threaded ring 43 limits the connecting rod 42 through the limiting ring 44, thus limiting the angle of the docking frame 45. Then, the connecting rod 42 is clamped outside the wire bracket, the docking frame 45 is wrapped around the wire bracket, and the threaded rod 47 is turned, causing the threaded rod 47 to push the clamping strip 49 downward through the limiting piece 410, and causing the clamping strip 49 to drive the sliding rod 48 to slide downward. Further, the clamping strip 49 contacts the wire bracket, so that the clamping strip 49 limits the docking frame 45 outside the wire bracket. And because the docking frame 45 is wrapped around the wire bracket, the clamping strip 49 preferably limits the docking frame 45 on the wire bracket. And because the clamping strip 49 is strip-shaped, the contact surface between the clamping strip 49 and the wire bracket is greatly increased, improving the stability of the docking frame 45 limited on the wire bracket. And then, a marker pen is used to mark the surface of the wire bracket in the positioning groove 46, so that during maintenance, by observing the marked trace, it can be judged whether the docking frame 45 has displaced, which helps the worker to check the displacement condition of the docking frame 45. By clamping the docking frame 45 outside the wire bracket and then turning the threaded rod 47, causing the threaded rod 47 to push the clamping strip 49 downward through the limiting piece 410 and making the clamping strip 49 contact the wire bracket, the purpose of easily limiting the docking frame 45 outside the wire bracket can be achieved. And because the docking frame 45 is wrapped around the wire bracket, the clamping strip 49 preferably limits the docking frame 45 on the wire bracket. And because the clamping strip 49 is strip-shaped, the contact surface between the clamping strip 49 and the wire bracket is greatly increased, improving the stability of the docking frame 45 limited on the wire bracket.
