Description

Technical Field

[0001] The invention relates to a special device for clamping and scanning the microscopic morphology of an insulator and a use method thereof, belonging to the technical field of power grid safety monitoring. Background Art

[0002] With the development of my country's industry and the construction of industrial and mining enterprises, more and more pollutants are discharged into the air, and environmental pollution is becoming increasingly serious. The pollution level in the areas where the power grid is located is constantly increasing, and the external insulation equipment is polluted faster. On the other hand, the power grid voltage is constantly increasing, the network is constantly expanding, and the number of AC and DC interconnections is increasing. Power grid pollution flashover accidents occur from time to time and have an increasing trend.

[0003] The root cause of pollution flashover accidents on high-voltage overhead lines is that dirty substances are deposited on the surface of insulators, which reduces the surface resistance of insulators under humid conditions and increases leakage current, thus causing flashover. Since the frequency of pollution flashover tripping is very high and the re-combination power after tripping is very low, it is easy to cause large-scale, long-term vicious power outages, and even cause local power grid decoupling and the collapse and paralysis of the entire power grid, seriously affecting industrial and agricultural production safety and people's lives.

[0004] Therefore, pollution flashover is extremely harmful. It is unprecedentedly urgent to adopt effective methods to prevent pollution flashover and solve the pollution flashover problem. Preventing large-scale pollution flashover accidents is one of the important contents of improving power supply reliability. Adopting effective measures to reduce and prevent pollution flashover accidents is an important guarantee for the safe operation of the power grid.

[0005] Regular rotation cleaning of each line has long been a traditional measure for the power system to maintain the safe operation of power transmission and transformation equipment. This was feasible in the early stages of power grid construction when the scale was small, the voltage level was low, and the maintenance personnel were relatively sufficient and responsible. Nowadays, the scale of the power grid has changed a lot, and the use of traditional methods has become a huge workload. One of the reasons why various anti-pollution measures are not very ideal for the prevention of pollution flashover is that it is difficult to accurately monitor the pollution accumulation of external insulation equipment. Anti-pollution measures are designed and adjusted according to the pollution level of external insulation equipment. Untrue and inaccurate pollution level measurements will inevitably affect the timely and accurate warning of pollution flashover.

[0006] Using high-precision methods to monitor the pollution level of insulators, study the accumulation process of pollution, and timely and accurately warn and prevent the occurrence of pollution flashover accidents is one of the most effective means of anti-pollution work, which is particularly important for the safe and economical operation of power grids.
