Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a high-voltage suspension porcelain insulator. Background Art

[0002] Insulators are a special type of insulating control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on electric poles, and gradually developed into high-type high-voltage electric wire connection towers with many disc-shaped insulators hung on one end. It is used to increase the creepage distance. It is usually made of glass or ceramic, which is called an insulator. At present, insulators come in various styles, but the structure is relatively fixed and single. They can be simply divided into hardware, core rods, umbrella skirts, and steel feet. Among them, cylindrical insulators are relatively standard electrical insulators with high performance and light structure. Suspension porcelain insulators are a type of insulator with low maintenance costs and high safety and reliability. Suspension porcelain insulators mainly include insulating disks, steel caps and steel feet, which are generally connected one by one by bolts. However, since the suspension porcelain insulators are fixed and formed when leaving the factory, the distance between two adjacent insulating disks is difficult to adjust according to the usage scenario, which leads to a relatively small application range of the suspension porcelain insulators. At the same time, when the steel feet and steel caps of two suspension porcelain insulators are connected, since the staff needs to insert the bolts into the sockets of the steel feet and steel caps with one hand, it is difficult to align the sockets of the steel feet and steel caps with the other hand, making the entire connection process more laborious. To this end, we provide a high-voltage suspension porcelain insulator to solve the above problems. Utility Model Content

[0003] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the utility model proposes a high-voltage suspension porcelain insulator, including an insulating disk, a steel cap is fixedly arranged on the top of the insulating disk, a steel foot is arranged on the bottom of the insulating disk, a fixed disk is fixedly arranged on the bottom of the insulating disk, a gasket is arranged on the bottom of the fixed disk, a connecting piece is arranged on the bottom of the gasket, the bottom of the connecting piece is fixedly connected to the steel foot, a plurality of bolts are movable through the internal parts of the connecting piece and the gasket, the bolts are threadedly connected to the interior of the fixed disk, and limit blocks are fixedly arranged on both sides of the corresponding sockets of the steel feet.

[0004] Preferably, the plurality of bolts are arranged in a circular array with the fixing plate as the center, and the number of the bolts is 4-8.

[0005] Preferably, the bottom end of the limit block is provided with an arc-shaped groove which fits with the top end of the steel cap.

[0006] The beneficial technical effect of the utility model is as follows: by adding or reducing gaskets between the fixed disk and the connecting plate, and selecting bolts of appropriate length according to the number of gaskets, the connecting plate, the gasket and the fixed disk are then fixedly connected by bolts. Since the number of gaskets is adjusted, the distance between two adjacent insulating disks can be indirectly changed, so that the use of the suspension porcelain insulator can be adapted to different usage scenarios. The arc groove under the limit block is used to limit the top of the steel cap, which facilitates the staff to insert the bolts into the sockets of the steel cap and the steel foot for connection, and has certain practicality.
