Abstract
An object of the utility model is to provide an insulator of full skirt is climbed in cladding formula, including porcelain insulator, be equipped with a plurality of full skirts on porcelain insulator, it has the silastic layer to bond on the full skirt surface, and silastic layer cladding full skirt, and the silastic layer is greater than the thickness of other positions at full skirt edge part's thickness. By means of the structure, the insulator is long in service life, dirt can be prevented, and flashover can be effectively prevented.
Description
Technical Field
The application belongs to the technical field of high-voltage power transmission and transformation equipment, and relates to a coated type climbing-increasing umbrella skirt insulator.
Background
In a high-voltage line, an insulator is generally required to support and insulate a high-voltage line, and the insulator is exposed in a natural environment, so that a dirt substance with conductive performance can be accumulated on the surface of the insulator, the insulation level of the insulator is greatly reduced after the insulator is affected with damp in wet weather, and particularly in rainy and snowy weather, liquid with the dirt substance is easy to form surface conductance and leakage current to sharply increase, so that the flashover voltage of the insulator is remarkably reduced, and even the insulator can be flashover under the working voltage, and the safe operation of a power system is seriously influenced; the main factors causing such serious influences are the dirt and too many particles on the surface of the insulator, and if the insulator is cleaned and cleaned frequently, the workload is large, and the safety of workers is seriously influenced.
Disclosure of Invention
The utility model aims to provide an insulator of full skirt is climbed to cladding formula, including the porcelain insulator, be equipped with a plurality of full skirts on the porcelain insulator, it has the silastic-layer to bond on the full skirt surface, and silastic-layer cladding full skirt, and the silastic-layer is greater than the thickness of other positions at full skirt edge part's thickness.
Preferably, the silicone rubber layer protrudes in correspondence to the skirt edge portion, and the thickness of the protruding portion is gradually reduced.
Preferably, the edge of the silicone rubber layer extends downwards to form an olecranon.
Preferably, the diameter of one of the adjacent two sheds is larger than that of the other shed.
By means of the structure, the insulator is long in service life, dirt can be prevented, and flashover can be effectively prevented.

The embodiment of the application discloses insulator of cladding formula increase and climb full skirt, including porcelain insulator 10, be equipped with a plurality of full skirts (101, 102) on porcelain insulator 10, it has silicon rubber layer 20 to bond on full skirt (101, 102) surface, silicon rubber layer 20 cladding full skirt (101, 102), and silicon rubber layer 20 is greater than the thickness of silicon rubber layer 20 cladding on full skirt (101, 102) other positions at full skirt (101, 102) edge part's thickness.
Example one
Referring to fig. 1, in the porcelain insulator 10 having the above-described structure, a plurality of first sheds 101 and second sheds 102 are provided on the porcelain insulator 10, the first sheds 101 and the second sheds 102 are spaced apart from each other, the diameter of the second sheds 102 is larger than that of the first sheds 101, a silicone rubber layer 20 is bonded to the surface of the sheds 102, and the silicone rubber layer 20 covers the surface of the second sheds 102.
In addition, the thickness of the silicone rubber layer 20 at the edge part of the second shed 102 is larger than the thickness of the silicone rubber layer 20 coated on other positions of the second shed 102.
Example two
Referring to fig. 2, in the porcelain insulator 10, a plurality of first sheds 101 and second sheds 102 are arranged, the first sheds 101 and the second sheds 102 are arranged at intervals, the diameter of the second sheds 102 is larger than that of the first sheds 101, a silicone rubber layer 20 is bonded on the surface of the second sheds 102, the silicone rubber layer 20 covers the surface of the second sheds 102, the edge portions of the silicone rubber layer 20 corresponding to the second sheds 102 protrude, and the thickness of the protruding portions gradually decreases.
Preferably, the edges of the silicone rubber layer 20 extend downward to form olecranon 201, so as to prevent dirt from entering the lower surface of the second shed 102 (silicone rubber layer 20), and at the same time, facilitate rainwater drainage.
While the present application has been described by way of examples, those of ordinary skill in the art will appreciate that there are numerous variations and permutations of the present application that do not depart from the spirit of the present application and that the appended embodiments are intended to include such variations and permutations without departing from the present application.
