专利汇可以提供High voltage surge diverter专利检索,专利查询,专利分析的服务。并且A new technique for diverting high-voltage surges due to lightning or switching operations from a power line to ground. The surge diverting discharge takes place across the surface of solid dielectric insulators placed in an evacuated space inside a dielectric tube. Metallic ion shields are provided which intercept the discharge path and uphold a voltage between the electrodes of the diverter. The device has a more stable triggering level than prior art lightning arresters and it prevents the flow of power followthrough currents.,下面是High voltage surge diverter专利的具体信息内容。

1. A device for diverting electrical charge associated with a high-voltage surge from a high-voltage conductor to a grounded structure, which device includes: a. means defining an evacuated space including solid dielectric housing means; b. high potential electrode means in said space; c. low potential electrode means in said space; d. said low and high potential electrode means being spaced apart and confronting each other within said space in said dielectric housing means to define a discharge gap; e. solid dielectric insulator means positioned in said gap between said electrode means; f. a metallic ion shield positioned in said space within said housing means about said insulator means and spaced from said electrode means to intercept the natural path of electrical discharge over the surfaces of said insulator means in said gap; and g. means elEctrically isolated by said dielectric housing means for providing separate external electrical connections to said low and high potential electrode means.
2. A device according to claim 1 in which a said electrode means is finned.
3. A device according to claim 1 in which said insulator means includes a plurality of separate insulators and in which a said ion shield is retained between an adjacent pair of said insulators.
4. A device according to claim 1 in which said insulator means includes an insulator adapted to retain a said ion shield thereon.
5. A device according to claim 1 in which said insulator means is hollow and is adapted to accommodate an insulated conductor there through.
