Description

Technical Field

[0001] The utility model relates to the field of insulators, in particular to a suspension porcelain insulator with a stable steel cap connection. Background Art

[0002] Disc-shaped suspension porcelain insulators are the most widely used insulators for high-voltage overhead transmission lines. When in use, the single-piece insulators are combined into an insulator string of a certain length according to the insulation matching requirements of the line, and connected between the conductor and the tower through hardware to play the role of insulation and supporting the conductor. The insulator is mainly made of porcelain parts, iron caps and steel feet and other parts bonded by cement adhesive. According to the strength dispersion characteristics of porcelain parts, steel feet and iron caps, steel feet with simple shapes and the easiest strength to control are selected to control the strength of the entire insulator, so that the steel feet are destroyed before the iron caps and porcelain parts are destroyed, that is, most of the insulators are destroyed when the steel feet are destroyed, that is, the strength of the steel feet is the strength of the insulator.

[0003] However, during the use of insulators, they often shake due to the influence of wind in the air. The shaking of the insulator will cause wear of the steel feet and locking pins, thereby reducing the strength of the insulator. Secondly, the surface compressive stress of the insulator is low, which greatly reduces the porcelain destructive strength.

[0004] Therefore, it is necessary to propose a suspension porcelain insulator with a stable steel cap connection to solve the above problems. Utility Model Content

[0016] Technical effects and advantages of the utility model:

[0017] 1. In the actual operation of the present invention, after the two insulator bodies are connected by the iron cap and the steel foot, the telescopic rod at the bottom end of one insulator body can be inserted into the socket in the first rotating ring on the other insulator body to strengthen the connection strength between the two insulator bodies.

[0019] 3. Since the two extension plates are provided with repelling magnets inside, the two extension plates can be prevented from being blown by the wind and stay in a vertical line, so as to prevent raindrops from connecting into water columns and generating conductive paths when it rains, causing the two extension plates to intersect.

[0020] 4. When the insulating sweeping plate rotates, it will drive the corresponding first rotating ring and the second rotating ring to rotate. At this time, the telescopic rod will also move with it, so that wind at various angles can pass through the air outlet. The wind will blow the metal sheet to vibrate and make a sharp sound, which will disturb nearby birds, prevent them from approaching, and reduce the production of bird droppings on the insulator body.
