Description

Technical Field

[0001] This utility model relates to the field of electrical porcelain equipment technology, specifically to a windproof line post insulator. Background Technology

[0002] Insulators are critical components used in power systems and electrical equipment. Their main function is to provide electrical insulation and mechanical support, ensuring that current is transmitted along a specific path while preventing current leakage to non-target areas, such as supporting structures or the ground. Insulators come in various types, mainly classified as suspension insulators, pin insulators, composite insulators, and post insulators. Among these, post insulators are the most common. One end connects to the crossbar of the power tower, and the other end connects to the cable. Traditional post insulators are usually fixed using a rigid connection. In high-altitude or extreme weather conditions, high-voltage cables will sway violently under wind force, and the resulting stress can easily damage the insulator, reducing its service life and increasing power maintenance costs. A new type of insulator is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned issues, this utility model proposes a windproof line post insulator, comprising a ceramic post with several umbel skirts along its axial direction. The top of the ceramic post is connected to a ball seat via cement, and a ball joint at the bottom of a connector is embedded in the inner cavity of the ball seat. A cable is connected to the top of the connector, and a mounting screw is connected to the bottom of the ceramic post via cement.

[0004] Furthermore, a groove is cut into the top surface of the ceramic column, and the central boss of the groove fits into the open bottom surface of the inner cavity. The outer wall of the ball receiving seat is connected to the inner wall of the groove by cement.

[0005] Furthermore, the bottom connecting rod of the connector is inserted into the inner cavity through the top through hole of the ball joint, and the threaded end of the connecting rod is threaded to the threaded through hole of the ball joint and welded into a whole.

[0006] Furthermore, a wire-laying groove is opened on the top of the connector, and a cover plate is connected to the screw holes on both sides of the groove opening by bolts. A wire-pressing block is provided on the bottom surface of the cover plate, and the concave arc of the bottom surface of the wire-pressing block is combined with the wire-laying groove to form a circle.

[0007] Furthermore, a countersunk hole is opened in the center of the base of the ceramic column, and the head of the mounting screw is inserted into the countersunk hole. The wall of the mounting screw head is connected to the inner wall of the countersunk hole by cement.

[0008] Furthermore, several concave rings are provided on the outer wall of the ball receiving seat and the rod wall of the mounting screw head.

[0009] The beneficial effects of this utility model are as follows: This utility model connects the mounting hole on the crossbeam with the screw thread, and then connects the cable through the cable tray on the connector. The cable tray can be connected to the cover plate by bolts to prevent the cable from falling off. The connector is connected to the top of the ceramic column through a ball joint, which can achieve free rotation. This not only facilitates the installation and removal of the cable, but also leaves room for movement so that the insulator is not easily broken by strong winds. It has the characteristics of windproof and convenient. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figures 1 to 3As shown, a windproof line post insulator includes a ceramic post 1. The ceramic post 1 has several umbel skirts 101 along its axial direction. The top surface of the ceramic post 1 has a recessed groove 102. The central boss 103 of the recessed groove 102 is engaged with the open bottom surface of the inner cavity 201. The outer wall of the ball seat 2 has several concave rings to increase the surface area. A ball joint 301 is placed in the inner cavity 201 of the ball seat 2. The bottom connecting rod 302 of the terminal 3 is inserted into the inner cavity 201 from the top through hole of the ball seat 2. The inserted end of the connecting rod 302 is threaded to the threaded through hole of the ball joint 301 and welded into a whole. After welding, the ball seat 2 is connected to the boss 103. Then, the gap between the outer wall of the ball seat 2 and the inner wall of the recessed groove 102 is filled with cement.

[0018] In this embodiment, the top of the connector 3 has a cable groove 303, into which the cable 4 is inserted. The screw holes on both sides of the groove 303 are connected to a cover plate 6 via bolts. A pressure block 601 is provided on the bottom surface of the cover plate 6. The concave arc of the bottom surface of the pressure block 601 is joined with the cable groove 303 to form a circle, the size of which is clearance-fitted with the diameter of the target cable 4. A countersunk hole 104 is formed in the center of the base of the ceramic column 1. The head of the mounting screw 5 is inserted into the countersunk hole 104. Several concave rings are formed on the wall of the head of the mounting screw 5. The wall of the head of the mounting screw 5 is connected to the inner wall of the countersunk hole 104 by cement.

[0019] The working principle of this utility model is as follows:

[0020] During the fabrication of this insulator, the connecting rod 302 is threaded through the ball seat 2 and connected to the ball joint 301. The connecting rod 302 and the ball joint 301 are then welded together. The head of the connector 3 is pulled to insert the ball joint 301 into the inner cavity 201. After confirming that the ball joint 301 can move freely, the ball seat 2 is aligned with the boss 103. Cement is then used to fill the gap between the outer wall of the ball seat 2 and the inner wall of the groove 102. When the insulator needs to be installed, the mounting screw 5 is threaded into the mounting hole of the transverse platform. The cable 4 is then inserted into the cable tray 303, and the cover plate 6 is bolted on. The cable 4 is confined within the circle formed by the concave arc of the bottom surface of the pressure block 601 and the cable tray 303, completing the movable connection between the cable 4 and the ceramic post 1.

[0021] This utility model uses a screw rod 5 to connect to the mounting hole on the crossbeam, and then connects the cable 4 through the connector 3. The connector 3 is connected to the top of the ceramic column 1 through the ball joint 301, which can achieve free rotation. This facilitates the installation and removal of the cable 4, and also leaves room for movement so that the insulator is not easily broken by strong winds. It has the characteristics of windproof and convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
