Technical Field
The utility model relates to a transmission of electricity insulating apparatus field specifically is a maintenance umbrella.
Background
At present, insulators are widely applied in the power industry. The early insulator is usually a porcelain insulator, along with atmospheric environment deterioration, the air pollution level is higher and higher, and the porcelain insulator continuously generates pollution flashover accidents under the pollution accumulation condition, so that huge loss is caused to a power grid, and the stable operation of the power grid is seriously influenced. Then, a composite insulator is developed, and the composite insulator has the advantages of good mechanical property, strong corrosion resistance, good pollution-resistant, rain-flashing and ice-covering performance and the like.
In the early composite insulator, the long-term operation of the insulator cannot be supported by the performance of the material due to the problems of incomplete formula and the like. With the increase of the operation time, the phenomena of aging, damage and the like appear on the umbrella skirt on part of the composite insulator, so that the insulating property of the insulator is reduced, and the insulating requirement of equipment cannot be met. In order to solve the above problems, the aged insulators are usually replaced, so that a large amount of manpower and material resources are wasted, and the power transmission cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a maintenance umbrella, this maintenance umbrella can maintain the insulator that appears ageing, and the cost is lower relatively simultaneously.
In order to realize the purpose of the utility model, the utility model adopts the following technical means: a maintenance umbrella is used for repairing an insulator with an aged umbrella skirt, and comprises an insulator and at least one umbrella skirt covered outside the insulator, wherein the maintenance umbrella comprises a sleeve part arranged longitudinally and at least one repair umbrella skirt extending radially from the sleeve part, and the sleeve part can be sleeved on the outer surface of the insulator after the umbrella skirt is removed.
Above-mentioned maintenance umbrella owing to can replace ageing above-mentioned full skirt, need not change the whole root of above-mentioned insulator, also need not dismantle this insulator by equipment, has effectively solved the ageing problem of insulator, and this maintenance umbrella simple to operate has effectively reduced the cost of maintenance of insulator.
Preferably, the maintenance umbrella further comprises at least one longitudinally disposed seam formed by the maintenance umbrella being radially broken from the hub. The maintenance umbrella is covered on the insulator through the seam. More preferably, the seam is helically arranged in the longitudinal direction. The seam that this spiral set up has increased the length of this seam, can effectively avoid because the insulating properties difference of seam department leads to the breakdown current to puncture along the seam, destroys the insulating properties of insulator.
Preferably, the inner wall of the sleeve portion is provided with a projection. The inner wall of the maintenance umbrella and the outer surface of the insulator can generate a certain gap through the bulge, and then glue filling and bonding are carried out.

Detailed Description
As required, detailed embodiments of the present invention will be disclosed herein. However, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed manner, including employing various features disclosed herein in connection with which such features may not be explicitly disclosed.
The first embodiment is as follows:
as shown in fig. 1 to 3, the repair umbrella 100 of the present embodiment is used for repairing an insulator 10 in which a shed 12 is aged, and the insulator 10 includes a columnar insulator 11, a sheet-shaped shed 12 covering the insulator 11, and flanges 13 mounted at both ends of the insulator 11. Maintenance umbrella 100 includes a longitudinally disposed sleeve portion 110 and a repair shed 120 extending radially from the sleeve portion, maintenance umbrella 100 being radially broken from the hub to form a seam 130.
The insulator 11 is made of glass fiber reinforced plastic, twelve sheds 12 are coated outside the insulator 11, and six sheds 12 on the upper portion are aged. The longitudinal length of the sleeve portion 110 is the longitudinal height of the removed aged six-piece shed 12, and the inner diameter of the sleeve portion 110 is slightly larger than the outer diameter of the insulator 11. The repair shed 100 includes six repair sheds 120, and the six repair sheds 120 correspond to the six aged sheds 12 in shape and size one to one. The seam 130 is in a vertical orientation.
The maintenance umbrella 100 of the embodiment replaces the aged umbrella skirt 12 with the maintenance umbrella 100, and the maintenance umbrella 100 can be sleeved on the outer surface of the insulator 11 with the aged umbrella skirt 12 removed through the seam 130 without replacing the whole aged insulator 10 and removing the aged umbrella skirt 12 directly without detaching the insulator 10 from the device. The maintenance umbrella 100 of the embodiment effectively solves the problem of aging of the insulator 10, and reduces the maintenance cost of the insulator 10.
Example two:
as shown in fig. 2 to 4, the maintenance umbrella 200 of the present embodiment is used for repairing the insulator 10 according to the first embodiment of the present invention. Wherein the seam 230 is helically arranged in the longitudinal direction. The inner wall of the sleeve portion 210 is provided with a plurality of protrusions (not shown). Except for the above description, maintenance umbrella 200 of the present embodiment is the same in structure as maintenance umbrella 100 of the first embodiment.
In the maintenance umbrella 200 of the present embodiment, the seam 230 is spirally configured, so that the extending length of the seam 230 on the surface of the repair shed 220 is increased, and the insulation performance difference of the seam 230 can be effectively avoided, which causes the current to break down along the seam 230, and the insulation performance of the insulator 10 is damaged consistently. The arrangement of the protrusions can form a certain gap between the inner wall of the sleeve part 210 and the outer surface of the insulator 11, so that the injection and the uniform distribution of glue solution are facilitated, and the fixing reliability of the maintenance umbrella 200 is ensured.
While the invention has been described with reference to the above disclosure, it will be understood by those skilled in the art that various changes and modifications in the above-described structures and materials, including combinations of features disclosed herein either individually or in any combination, will be apparent to one skilled in the art from the disclosure herein.
