    • 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.
    • 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。

    • The present invention is directed to a downhole, high-current, low-impedance, feed-through connector for passing electrical current, preferably high frequency AC current, between a tool compartment having relatively high pressure and another tool compartment having relatively low pressure. The primary intended application of the present invention is to connect a radio frequency transmitter/receiver antenna to the antenna's tuning capacitors, but the present invention is applicable to any downhole application requiring the transmission of high electrical current across a barrier having a high pressure differential. This invention minimizes the force acting on the connector due to the high pressure differential by providing a conductor preferably having either a wave-like cross section or a multi-finned cross section, thereby minimizing the overall cross-sectional area of the connector yet providing sufficient cross-sectional area of the conductor to carry the necessary amount of electrical current.
    • 本发明涉及用于在具有相对较高压力的工具室和具有相对较低压力的另一工具室之间传递电流(优选高频AC电流)的井下高电流低阻抗馈通连接器。 本发明的主要目的在于将射频发射机/接收机天线连接到天线的调谐电容器,但是本发明可应用于需要高电流传输通过具有高压差的屏障的任何井下应用。 本发明通过提供优选地具有波形横截面或多翅片横截面的导体来最小化由于高压差而作用在连接器上的力,从而最小化连接器的总横截面积,同时提供足够的 导体的横截面积承载必要的电流量。
