变电站用RTV涂料自动喷涂装备研制

Automatic Spraying Equipment Research of RTV on Substation

室温硫化硅橡胶(RTV)防污闪涂料是提高输变电设备外绝缘性能的有效技术手段之一。现场喷涂主要采用人工喷涂方式,操作工人的喷涂经验、喷涂工艺直接影响到RTV后期运行性能。本文针对人工喷涂RTV所导致的涂层厚度不均匀、流淌等现象,开发出适用于站内支柱绝缘子的自动喷涂装置。该装置通过设置喷枪运行姿态,实现喷枪整体的圆周、上下、摆动三维运动。喷涂后现场检测调试发现,人工喷涂厚度在不同取样位置差异较大,而自动喷涂厚度则相对较均匀,自动喷涂装备能有效提高RTV喷涂质量和效率。

RTV is one of effective methods for 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,an automatic spraying equipment was developed to deal with uneven coating thickness,flow and other phenomena of artificial spraying. The device can help the spraying gun achieve circular,up and down and swinging three-dimensional motion by setting up the gun＇s posture parameters. After spraying,spot detection found that artificial spraying thickness difference is quite large,while automatic spraying thickness is relatively uniform,and the automatic spraying equipment can effectively improve the RTV coating quality and efficiency.
