摘要： A high-voltage bushing includes an insulating body disposed concentrically around a cylindrical winding support formed of electrically conductive material, and a sealing device for sealing a gap between the winding support and the insulating body. The sealing device includes a sealing element disposed in a circumferential sealing groove. The circumferential sealing groove is disposed in the winding support and accommodates the sealing element. A method for producing a high-voltage bushing includes placing an insulating body concentrically around a cylindrical winding support formed of electrically conductive material. The insulating body has mutually concentrically disposed insulating layers. A sealing element is introduced into a circumferential sealing groove in the winding support, and the insulating body is subsequently impregnated with a resin to seal a gap between the winding support and the insulating body.

摘要： The invention comprises dielectric isolators for use in aircraft fuel systems to control lightning induced current and allow dissipation of electrostatic charge. The dielectric isolators are configured to have a high enough impedance to limit lightning currents to low levels, but low enough impedance to allow electrostatic charge to dissipate without allowing buildup. Although the dielectric isolators may develop a potential difference across the dielectric length due to the effects of lightning currents and its inherent impedance, they are configured to withstand these induced voltages without dielectric breakdown or performance degradation. In one embodiment, the dielectric isolator includes a tube constructed of a composition including a thermoplastic organic polymer (e.g., PEEK) and carbon nanotubes, and a pair of fittings attached to opposing ends of the tube. In another embodiment, the dielectric isolator includes a tube, an outer annular portion, and an interconnecting web, each constructed from the composition including a thermoplastic organic polymer (e.g., PEEK) and carbon nanotubes. This later embodiment is an integrally formed one-piece structure. The dielectric isolator is capable of exhibiting an electrical resistance from about 105Ω to 108Ω at an applied potential of greater than 500 volts DC when measured from one fitting to the other fitting.

摘要： An improved hollow core composite bushing for use in, for example, a dead tank circuit breaker, is smaller and lighter and offers other advantages over previous designs. The hollow core bushing includes therein a fiber reinforced plastic (FRP) elongated tube that operates to increase the dielectric constant between a conductor and a transition shield. By placing the transition shield external to the hollow core bushing and providing the FRP tube between the conductor and transition shield, the dielectric constant between the shield and conductor is increased thus allowing the inner diameter of the shield and outer diameter of the bushing to be decreased. In addition, the transition shield may be an integral part of the flange that is mounted to the bushing current transformer support column or interrupter enclosure of the dead tank circuit breaker thus further reducing the diameter and overall size of the bushing. Further, the transition shield may be an integral part of the FRP tube.
摘要翻译：用于例如死水箱断路器的改进的中空芯复合衬套更小更轻，并且具有优于先前设计的其它优点。中空芯衬套包括纤维增强塑料（FRP）细长管，其操作以增加导体和过渡屏蔽之间的介电常数。通过将过渡屏蔽件放置在中空芯轴套外部并将FRP管设置在导体和过渡屏蔽之间，屏蔽和导体之间的介电常数增加，从而允许屏蔽的内径和衬套的外径减小。此外，过渡屏蔽可以是安装到死槽断路器的套管电流互感器支撑柱或断续器外壳上的凸缘的组成部分，从而进一步减小衬套的直径和总体尺寸。此外，过渡屏蔽可以是FRP管的组成部分。

摘要： A high voltage porcelain insulator has a plurality of sheds extending laterally thereof at spaced apart locations therealong. The creepage path length of the shedded insulator is extended by mounting polymeric insulating creepage extenders on the porcelain sheds. The creepage extenders do not extend completely around the periphery of the sheds but leave a gap. Preferably the gaps of adjacent creepage extenders along the insulator are not aligned.
