RTV Automatic Spraying Equipment Research of Post Insulators

RTV is one of effective methods of power transmission equipment external insulation properties improving. However, the performance of RTV coating was affected by spraying operation, which was mainly artificial spraying on site. In this paper, automatic spraying equipment was developed to deal with the uneven coating thickness, flow and other phenomena of artificial spraying. The device implemented the circumference of the spraying gun, up and down, swinging three-dimensional motion by setting the gun running posture parameters. It could be found out that the automatic spraying equipment highly improved the RTV coating quality and efficiency.
