Description
Technical Field

Background
The composite insulator is put into use, and plays a great role in improving the pollution flashover resistance level of the power transmission line and maintaining the safe operation of the power grid. The composite insulator is widely applied to power transmission lines, particularly ultra-high voltage power transmission lines, due to the excellent pollution flashover resistance, and is basically adopted at present. The composite insulator is selected, so that the pollution flashover resistance of the extra-high voltage circuit is improved, the string length of the insulator is greatly reduced, the size of a pole tower is reduced, and the engineering cost is reduced. However, the composite insulator has the characteristics of small umbrella spacing, easy bridging by ice ribs and electric arcs and the like, and under the ice-covered meteorological conditions, the electric performance of the composite insulator is greatly reduced because the ice ribs bridge the umbrella skirt gaps, the composite insulator with the existing structure has no obvious advantage when used in an ice-covered area, and the composite insulator has repeated ice flash tripping in the ice-covered area. Along with the continuous continuation of the construction of the power grid in China, more and more power transmission lines pass through the regions with serious ice coating, and the lines are large in multipath and long in length and pass through the regions with serious ice coating in mountain areas. According to statistics, the direct current transmission line of the national power grid company system in 2005-2010 trips 41 times due to ice coating galloping, wherein the operation is stopped for 14 times.
In order to solve the technical problems, the technical personnel in the art generally improve the composite insulator from two aspects, namely, the structural shape is improved, and the surface of the composite insulator is coated with impregnating coating and silicone rubber besides the requirements of relevant mechanical stretching, bending load and the like, so that the technical bottleneck existing in the use of the composite insulator in a heavy ice area is solved, and the application of the composite insulator in the heavy ice area is greatly promoted. In the production process of coating the surface of the composite insulator with the impregnating coating and the silicone rubber, the prior art adopts a manual impregnating mode, so that the method not only consumes labor and has low efficiency, but also has uneven and excessive adhesion of the coating and the silicone rubber after impregnation.
