500kV变电站支柱绝缘子智能喷涂RTV装置的研制

Development of Intelligent Spraying RTV Device for Pillar Insulator of 500 kV Substation

为预防污闪事故的发生、提高输变电设备的外绝缘性能,目前行业普遍采用在高压设备外绝缘表面人工喷涂RTV防污闪涂料的方式。本文开发研制一种新型、实用、高效的支柱绝缘子智能喷涂RTV装置,其喷涂压力可高达1500 PSI,设计摆动开合的悬臂式旋转喷涂结构,在不拆卸支柱绝缘子的条件下可直接进行全自动喷涂作业,精准控制喷涂位置与喷涂流量,大大提高涂层质量、喷涂效率与涂料利用率,本装置集喷涂、清洗、吹干与散料回收四种功能于一体,操作简单方便,设备稳定可靠,能够满足节能环保、安全快速以及柔性生产的需要,适应高质、高效与智能化的喷涂作业发展趋势,具有良好的实用性和可推广性。

In order to prevent pollution flashover accidents and improve the external insulation performance of power transmission and transformation equipment,RTV anti pollution flashover coating is widely used on the external insulation surface of high-voltage equipment.In this paper,a new,practical and efficient intelligent spraying RTV device for pillar insulator was developed with spray pressure up to 1500 PSI.The cantilever type rotary spraying structure was designed,which can directly carry out full-automatic spraying operation without dismantling pillar insulator.The spraying position and spraying flow can be precisely controlled so that the coating quality,spraying efficiency and coating utilization rate can be greatly improved.This device integrates spraying,cleaning,drying and bulk material recovery with simple and convenient operation,and the equipment is stable and reliable.It can meet the needs of energy conservation,environmental protection,safety,fast and flexible production,also adapt to the development trend of high-quality,high-efficiency and intelligent spraying operation with good practicability and scalability.
