Description

Technical Field

[0001] The invention belongs to the technical field of molds, and particularly relates to an anti-icing high-voltage ceramic insulator and a using method thereof. Background Art

[0002] Ceramic insulators have good electrical and mechanical properties and are important components of substations and transmission lines. High-voltage ceramic insulators are baked from quartz, feldspar, clay, and alumina. At present, for the high-voltage ceramic insulators used in transmission lines, the connection between the ceramic insulator body and the connecting fitting is not firm, and external rainwater, dust, etc. easily enter the gap between the ceramic insulator body and the connecting fitting, resulting in damage to the ceramic insulator body and affecting the safe operation of the transmission line. In snowy and icy weather, ice and snow are easily attached to the outside of the high-voltage ceramic insulator, resulting in short-circuit power failure and large-scale power outages. Summary of the Invention

[0003] The purpose of the invention is to provide an anti-icing high-voltage ceramic insulator and a using method thereof for the deficiencies of the prior art. This insulator can effectively prevent ice and snow from attaching to the surface of the insulator body, and at the same time can buffer external impacts, thereby effectively extending the service life of the insulator.

[0004] The purpose of the invention is realized as follows: An anti-icing high-voltage ceramic insulator includes an insulator body. The insulator body includes an insulating column and a plurality of insulator discs. The insulator discs are sequentially arranged on the insulating column from top to bottom. A protective structure is sleeved outside the insulator body. The protective structure includes a protective shell sleeved outside the insulator body. Upper and lower connectors are respectively arranged on the upper and lower surfaces of the protective shell. The upper and lower ends of the insulating column are respectively detachably connected to the upper and lower connectors. Elastic buffer mechanisms are arranged on the side and top of the protective shell.

[0005] Further, the elastic buffer mechanism includes a lateral protection plate and a top protection plate. The lateral protection plate and the top protection plate are respectively connected to the side and top surfaces of the protective shell. A lateral guiding buffer mechanism is arranged between the lateral protection plate and the protective shell, and a vertical guiding buffer mechanism is arranged between the top protection plate and the protective shell. Through the lateral guiding buffer mechanism and the vertical guiding buffer mechanism, the external impacts received by the lateral protection plate and the top protection plate can be absorbed and buffered to prevent damage to the insulator body.

[0006] Further, the lateral guiding buffer mechanism includes a lateral guiding column fixed on the inner side surface of the lateral protection plate. The lateral guiding column is slidably connected to the inner and outer sides of the side wall of the protective shell. A buffer spring A is arranged between the lateral protection plate and the side wall of the protective shell. When the lateral protection plate encounters external impacts such as hail, it will squeeze and compress the spring A towards the protective shell, and most of the impact force can be absorbed through the compression of the spring A.

[0007] Further, the included angle between the lateral protection plate and the axis of the insulating column is greater than 0° and less than 30°. The lateral protection plate can not only buffer the impact in the horizontal direction, but also buffer the impact force in the downward or obliquely downward direction.

[0008] Further, a spherical hinge is provided between the lateral guiding column and the side wall of the protective shell. The lateral guiding column is slidably connected to and from the rotating hinge, and the rotating hinge is rotatably connected to the side wall of the protective shell. The lateral guiding column and the side wall of the protective shell are connected by a spherical hinge, so that the lateral protection plate can be turned in different directions under the action of an external impact.

[0009] Further, the vertical guiding and buffering mechanism includes a vertical guiding column fixed to the lower surface of the top protection plate. The vertical guiding column is slidably connected up and down with the top of the protective shell. A buffer spring B is provided between the top protection plate and the upper surface of the protective shell. When the top protection plate encounters an external impact such as hail, it will squeeze and compress the spring B towards the protective shell, and most of the impact force can be absorbed by the compression of the spring B.

[0010] Further, the top protection plate adopts an umbrella-shaped structure to prevent rainwater or sundries from accumulating on the top of the top protection plate.

[0011] Further, the outer surfaces of the top protection plate, the lateral protection plate and the protective shell are coated with a waterproof coating.

[0012] Further, the top and bottom ends of the insulating column are respectively sleeved outside the upper connecting piece and the lower connecting piece, and the lower connecting piece is fixedly connected to the protective shell. The upper connecting piece is connected to the protective shell by a thread. The bottom of the protective shell and the side wall of the protective shell are detachably connected by bolts, which is convenient for replacing the insulator body or the protective shell as needed.

[0013] A method for using an anti-icing high-voltage ceramic insulator includes the following steps: Step 1: Open the top of the protective shell, sleeve the bottom end of the insulating column in the insulator body outside the lower connecting piece, then fasten and install the top of the protective shell, and finally tighten the upper connecting piece, and screw the bottom end of the upper connecting piece into the limiting hole at the top end of the insulating column to fix the position of the insulating column; Step 2: Insert the lower connecting piece at the bottom end of the insulating column into the mounting bracket and tighten the mounting nut to install the insulator body; Step 3: Connect the insulator to the high-voltage wire and the electric tower, electric pole or other support structures through the upper connecting piece and the lower connecting piece. Step 4, when the lateral protection plate or the top protection plate encounters external impacts such as hail, it will squeeze the compression spring A or the compression spring B towards the protection shell. Most of the impact force can be absorbed through the compression spring A or the compression spring B to prevent the external impact from damaging the insulator body.

[0014] Advantages of the present invention: 1. A protection mechanism is installed outside the insulator body of the present invention. Through the protection mechanism, the insulator body can be protected to reduce the damage caused by external impacts to the insulator.

[0015] 2. A waterproof coating is applied on the outer surfaces of the top protection plate, the lateral protection plate and the protection shell of the present invention to prevent rainwater, etc. from staying on their surfaces and freezing under low-temperature conditions.

[0016] 3. The insulator body and the protection mechanism of the present invention are connected in a detachable manner, and the protection mechanism or the insulator body can be replaced as needed. Description of the Drawings

[0028] In one embodiment of the present invention, as Figure 1 shown, the included angle between the lateral protection plate 6 and the axis of the insulating column 1 is greater than 0° and less than 30°. The lateral protection plate 6 can not only buffer the impact in the horizontal direction, but also buffer the impact force in the downward or obliquely downward direction.

[0029] In one embodiment of the present invention, as Figure 1 shown, a spherical hinge 10 is provided between the lateral guiding column 8 and the side wall of the protection shell 3.
