Abstract
The activities of insulator washing are crucial to ensure the maintenance of the electricity supply, avoiding power outages due to malfunctioning of the insulators caused by salt spray deposited, especially in coastal regions, also due to environmental pollution. During the development of an intelligent system for washing distribution network insulators, it was observed the need for studying the hydro jetting nozzles to be used in the washing fluid outlet, in order to ensure the achievement of the desired requirements in the cleaning procedure. The objective of this work is to present the development, evaluation, and selection of hydro jetting nozzles. To characterize the nozzles, a performance simulation was carried out with a range of opening diameters, pre-selected from the literature. From the manufacturing of nine designed nozzles, bench tests were performed aiming to verify the jet behavior for each of them, concerning the monitoring of the working system pressure, spray opening, impact force measurement and flow rate. The results indicate that there is an increase in the pressure and flow rate as the passage diameter increases. To define the best nozzle for use, insulator washings were performed and the efficiency of each nozzle was evaluated, considering the visual aspect and its respective water consumption.
