摘要： A composite insulator containing means for providing early warning of impending failure due to stress corrosion cracking, flashunder, or destruction of the rod by discharge activity conditions is described. A composite insulator comprising a fiberglass rod surrounded by a polymer housing and connected with metal end fittings on either end of the rod is doped with a dye-based chemical dopant. The dopant is located around the vicinity of the outer surface of the fiberglass rod. The dopant is formulated to possess migration and diffusion characteristics, and to be inert in dry conditions and compatible with the insulator components. The dopant is positioned within the insulator such that upon the penetration of moisture through the housing to the rod through a permeation pathway in the outer surface of the insulator, the dopant will become activated and will leach out of the same permeation pathway or diffuse through the housing. The activated dopant then creates a deposit or stain on the outer surface of the insulator housing. The dopant comprises an oil-soluble dye, an indicator, or a stain compound that can either be visually identified, or is sensitive to radiation at one or more specific wavelengths. The dopant could also be formulated by a nanoparticle enabled material. Deposits of activated dopant on the outer surface of the insulator can be detected upon imaging of the outer surface of the insulator by appropriate imaging instruments or the naked eye.
摘要翻译：描述了一种用于通过放电活动条件提供由于应力腐蚀开裂，闪光或棒的破坏而导致的即将发生故障的预警装置。复合绝缘体包括由聚合物壳体包围并与杆的任一端上的金属端配件连接的玻璃纤维棒，其掺杂有基于染料的化学掺杂剂。掺杂剂位于玻璃纤维棒的外表面附近。掺杂剂被配制为具有迁移和扩散特性，并且在干燥条件下是惰性的并且与绝缘体组分相容。掺杂剂定位在绝缘体内，使得当通过绝缘体的外表面中的渗透通道将水分穿过壳体穿过壳体时，掺杂剂将被激活并且将从相同的渗透途径浸出或扩散通过住房。活化的掺杂剂然后在绝缘体外壳的外表面上产生沉积物或污渍。掺杂剂包括油溶性染料，指示剂或染色剂，其可以在视觉上被鉴定或者对一种或多种特定波长的辐射敏感。掺杂剂也可以由具有纳米颗粒的材料制成。通过适当的成像仪器或肉眼对绝缘体的外表面进行成像时，可以检测绝缘体外表面上活化的掺杂剂的沉积。
