Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power equipment, in particular to a porcelain insulator fitting. Background Art
[0002] Line porcelain insulators generally use hanging hardware. Connecting the hardware end to end and performing simple fixing treatment can achieve the connection of multiple insulators. Under strong wind conditions, the insulator string connected in this way will be deflected by the wind, resulting in a decrease in the gap between the conductor and the tower or conductor, greatly increasing the risk of air gap breakdown. Especially in high-altitude strong wind areas, wind deviation has always been a major threat to the stability of line operation. Utility Model Content
[0003] The purpose of the utility model is to solve the above problems and provide a porcelain insulator hardware.
[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0005] A porcelain insulator hardware, comprising: a high-voltage side hardware part and a low-voltage side hardware part;
[0006] A first connecting component is provided at the central end surface of the high-pressure side hardware part, and a second connecting component is provided at the central end surface of the low-pressure side hardware part;
[0007] The first connecting component and the second connecting component fit together to keep the high-pressure side fitting and the low-pressure side fitting relatively fixed.
[0008] As a further description of the above technical solution, the first connecting component is a bolt fixedly connected to the high-voltage side fitting part.
[0009] As a further description of the above technical solution, the second connecting component is a threaded hole opened at the center of the low-pressure side fitting.
[0010] As a further description of the above technical solution, an annular groove is provided on the end surface of the low-pressure side fitting part.
[0011] As a further description of the above technical solution, an annular protrusion matching the annular groove is provided on the inner end surface of the high-voltage side hardware part.
[0012] As a further description of the above technical solution, a plurality of reinforcing ribs are provided on the inner side surface of the high-voltage side fitting part.
[0013] As a further description of the above technical solution, the high-voltage side fitting part is connected to the connecting component one through a fixing member.

[0015] As a further description of the above technical solution, the fixing parts are cement adhesive and cast iron.
[0016] The beneficial effects of the utility model are as follows:
[0017] The utility model screws the low-voltage hardware onto the high-voltage hardware, and after installation, there is no mutual rotation between adjacent insulator pieces, so that the entire insulator string becomes one. Under the action of strong wind, the insulator string can remain relatively still with the pole tower and will not swing under the action of wind force, thereby achieving the effect of resisting wind deflection.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.
[0024] like Figure 1 and Figure 3 As shown, in one embodiment, a porcelain insulator fitting specifically comprises:
[0025] A high-pressure side fitting part 1 and a low-pressure side fitting part 3;
[0026] A connecting component 1 2 is provided at the central end surface of the high-pressure side hardware part 1. In the present embodiment, the connecting component 1 2 is a bolt fixedly connected to the high-pressure side hardware part 1. A connecting component 2 4 is provided at the central end surface of the low-pressure side hardware part 3. In the present embodiment, the connecting component 2 4 is a threaded hole opened at the center of the low-pressure side hardware part 3. At the same time, the bolt and the threaded hole are adapted. The adaptation here means that the bolt and the threaded hole can be rotatably connected as one and cannot be directly moved relative to each other in the axial direction.
[0027] The connection part 1 2 and the connection part 2 4 fit each other to keep the high-voltage side fittings relatively fixed to the low-voltage side fittings. Specifically, when two or more porcelain insulator fittings are connected, the connection part 1 2 of one porcelain insulator fitting is connected to the connection part 2 4 of another porcelain insulator fitting. By analogy, multiple porcelain insulator fittings can be connected. After the connection is completed, there is no mutual rotation between adjacent porcelain insulator fittings, so that the entire insulator string becomes one. Under the action of strong wind, the insulator string can remain relatively still with the pole tower and is not swung by the wind, thereby achieving the effect of resisting wind deviation.
[0028] refer to Figure 2 In another embodiment, the difference from the previous embodiment is that an annular groove 5 is provided on the end face of the low-voltage side fitting part 3, and an annular protrusion 6 matching the annular groove 5 is provided on the inner end face of the high-voltage side fitting part 1. When the two insulators are connected, the annular protrusion 6 can be inserted into the annular groove 5 accordingly, so that the connection between the two insulators is more stable and the ability to resist wind deflection is improved.
[0029] Furthermore, the high-pressure side hardware part 1 and the connecting component 2 are connected through the fixing part 8, and the high-pressure side hardware part 1 and the low-pressure side hardware part 3 are connected through the fixing part 8, and the fixing part 8 can be cement adhesive and cast iron, so that the high-pressure side hardware part 1 and the connecting component 2 can be stably connected, and the high-pressure side hardware part 1 and the low-pressure side hardware part 3 can also be connected more stably.
[0030] Furthermore, a plurality of reinforcing ribs 7 are provided on the inner side surface of the high-voltage side fitting part 1, which can effectively improve the strength of the insulator.
[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
