The standard type insulator is an industrial product, which is used for insulating and suspending wires in high-voltage and high-voltage AC and DC transmission lines.
　　Standard insulators are an important part of transmission lines. They are realistic and innovative electrical insulators and important structural supports. The performance of insulators and the rationality of their configuration directly affect the safe and stable operation of the line. The insulators used in the transmission lines of the power supply bureau are mainly divided into two categories. One is the disc-type suspension glass insulators used in tension strings, and the other is rod-type suspension composite insulators used in suspension strings and jumper strings. In long-term operation, the two types of insulators show different operating performance and characteristics.
　　1. Targeted line inspection
　　In order to avoid pollution flashover accidents on line insulators, it is necessary to conduct targeted line inspections first. During the inspection during the day, you can carefully listen to the sound at the insulator, and judge whether there is any abnormality in the insulator according to the sound. If you can hear the sound of discharge, it means that there is a certain problem, which needs to be solved. Moreover, in rainy and snowy weather, pollution flashover of transmission lines is more likely to occur. At this time, it is necessary to strengthen environmental monitoring, understand the surrounding environmental conditions in a timely manner, and provide protection for the insulation performance of insulators. At the same time, maintenance work must be carried out regularly. During the maintenance process, the quality of the insulators should be tested, and the zero-value insulators should be found in time, and replaced. This effectively protects the performance of the insulators and provides power transmission lines. normal operation provided assistance.
　　2. Regularly clean the insulators
　　During the long-term operation of the transmission line, a layer of impurities will be attached to the surface, which will cause certain damage to the insulation performance of the insulator. Therefore, in order to protect the insulation performance of the insulator, cleaning work can be carried out. Surface impurities are removed. In the cleaning process, it can be divided into different cleaning levels according to different environments. For example, in a very polluted environment, it is designated as an important cleaning area. When cleaning this area, it should be cleaned more than 3 times a year. , in a generally polluted environment, it is designated as a general cleaning area, and when cleaning the area, it must be protected more than twice a year; in an environment with very low pollution, it is designated as a light cleaning area, and the area is cleaned When cleaning, it is enough to do it once a year'". When cleaning, you can use the corresponding dry wipe agent, and cooperate with plastic balls, gloves and other tools to clean the insulator, and the effect is excellent to remove impurities on the surface of the insulator. And in While cleaning, it is also necessary to carefully inspect the
　　insulators to see if there are cracks, damages and other defects on the surface, and replace them in time when problems are found
　　. A lot of work is required for prevention, which will increase the investment of power companies and reduce the growth rate of economic benefits. Therefore, in the transmission line, insulators with excellent performance can be used to solve the problem of ineffectiveness. The problem of pollution flashover will be solved, and it will also increase the economic benefits of the enterprise. First of all, the anti-pollution insulator can be used. In this insulator, the double skirt creepage distance is added, which improves the creepage distance of the outer insulation of the insulator and the high working height of the insulator. The ratio of the voltage effect to the excellent value has reached the relevant requirements. Moreover, on the inner skirt, it is a smooth inclined plane. When impurities are attached to the insulator, it will automatically slide down, increasing its Cleanliness, it is difficult to accumulate dirt. Secondly, synthetic silicone rubber insulators can be used. Due to the characteristics of aging and hydrophobic properties of synthetic silicone rubber, insulators made of this material also have these characteristics. This insulator has excellent anti-pollution performance, which can effectively reduce the probability of pollution flashover accidents. However, in areas with serious pollution areas, not only the workload is heavy, the investment cost is high, and the time to play a preventive role is not very long. Therefore, when preventing these areas, you can apply anti-fouling paint with excellent effect on the surface of the insulator, and all the above-mentioned problems will be solved.
