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 a power grid. Composite insulators are more and more widely applied to power transmission lines due to excellent pollution flashover resistance, particularly ultra-high voltage power transmission lines, and at present, composite insulators are basically adopted. The selected composite insulator not only improves the pollution flashover resistance of the extra-high voltage line, but also greatly reduces the length of the insulator string, reduces the size of the pole tower and reduces the construction cost. However, the composite insulator generally has the characteristics of small umbrella spacing, easiness in bridging of an ice edge and an electric arc and the like, under the ice-covered weather condition, the electrical performance of the composite insulator is greatly reduced due to the fact that the ice edge bridges the umbrella skirt gap, the composite insulator with the existing structure is not obviously advantageous when used in an ice-covered area, and ice flash tripping is caused for many times in the ice-covered area. With the continuous continuation of the power grid construction in China, more and more power transmission lines pass through regions with severe ice coating, most of the lines are long in path and pass through regions with severe ice coating in mountainous regions. According to statistics, in 2005-2010, the direct current transmission line of the national grid company system trips for 41 times due to ice coating galloping, wherein the operation is stopped for 14 times.
In order to solve the above technical problems, a person skilled in the art generally improves the composite insulator from two aspects, one is from the aspect of structural shape, and the other is to coat and soak paint and silicone rubber on the surface of the composite insulator besides the requirements of relevant mechanical tension, bending load and the like, so as to solve the technical bottleneck existing in the use of the composite insulator in a heavy ice area and greatly promote the application of the composite insulator in the heavy ice area. In the production process of coating and infiltrating paint and silicon rubber on the surface of the composite insulator, the prior art adopts a manual infiltration mode, the method not only consumes labor and has low efficiency, but also has the phenomena of uneven and excessive adhesion of the paint and the silicon rubber after infiltration.
