Description

technical field [0001] The invention relates to the field of electric power safety, in particular to a portable insulator pollution loss coefficient research device and method. Background technique [0002] The research on the fouling characteristics of insulators is an important basis for the design, operation and maintenance of electric power external insulation, and rainfall cleaning is an important link in the process of fouling. To comprehensively study the change law of fouling of insulators, it is necessary to clean the rain. To carry out systematic research, it is necessary to build a set of easy-to-adjust, stable and reliable insulator pollution loss coefficient research device, which is used to study the influence of rainfall characteristic parameters and insulator parameters on the rainfall cleaning effect.

AI Technical Summary

Problems solved by technology

The defects of the device are: the device adopts a fixed structure, which is not easy to disassemble and transport. When carrying out the simulated rainfall experiment, the sample needs to be transported back to the laboratory for research. For the natural pollution insulator sample, it is easy to cause pollution during the transportation process. At the same time, when the quality of the sample is large or the quantity is large, it will bring great inconvenience to the research work due to the limitation of transportation conditions; the device does not consider whether the raindrops can reach the terminal velocity in the selection of the height of the nozzle, and the design does not consider the impact on the kinetic energy of rainfall. The adjustment and measurement of parameters, in fact, the kinetic energy of rainfall directly determines the impact of raindrops on the surface of the test object. It is an important parameter to measure the mechanical erosion effect of raindrops and an important factor affecting the cleaning effect of insoluble pollution on the surface of insulators. The device Measuring the kinetic energy of rainfall is very complicated, and cannot effectively adjust the parameters of kinetic energy of rainfall, and it is difficult to carry out in-depth research on the mechanism of rainfall cleaning
