专利汇可以提供Spark gap system for magnetically quenched surge voltage arrester专利检索,专利查询,专利分析的服务。并且A spark gap system for a surge voltage arrester of the magnetically quenched type is composed of a stack of superposed plates each of which is provided with a recess which defines an arc chamber and a pair of spaced electrodes therein and between which an arc can be struck and lengthened by the magnetic field. The pairs of electrodes in adjacent arc chambers are electrically connected in parallel, and an arrangement of ducts which provide an inter-communication between adjacent chambers permit the ionized gas formed by an arc in either chamber after being lengthened to pass to the other chamber to assist in striking an arc in the latter chamber as the arc in the first-mentioned chamber is extinguished. The arc is thus enabled to be transferred back and forth between adjacent arc chambers until the current has been reduced to such an extent that no further arc can be sustained.,下面是Spark gap system for magnetically quenched surge voltage arrester专利的具体信息内容。

1. A spark gap system for a surge voltage arrester of the magnetically quenched type which comprises a stack of superposed plates each of which is provided with a recess defining an arc chamber, a pair of spaced electrodes located in each such chamber and between which an arc can be struck and lengthened under the influence of the magnetic field, duct means formed in adjacent plates and which serve to interconnect the respective arc chambers of said plates whereby ionized gas formed by an arc struck in a first one of said chambers is passed to the other chamber for assistance in striking the arc in said other chamber accompanied by extinction of the arc in said first chamber, and means connecting the pairs of spaced electrodes in said chambers electrically in parallel.
2. A spark gap system as defined in claim 1 for a surge voltage arrester of the magnetically quenched type wherein each plate is circular, wherein the recess in each said circular plate is configured as a sector extending from substantially the center of the plate to the periphery thereof, wherein the electrodes in each recess are located such as to establish a strike point for the arc drawn therebetween at substantially the center of the plate, and wherein said duct means includes a duct extending radially outward from tHe recess at the center of each plate and through which the ionized gas flows in returning from one recess to the other.
