<p><P>PROBLEM TO BE SOLVED: To provide a small size vacuum switch, in which a movable electrode reduces the length from a fixed electrode to a power source and a load side cable head, to reduce power loss and heat generation. <P>SOLUTION: In this vacuum switch, the movable electrode 7 connected to a load side conductor via a flexible conductor 22 opens and closes with the fixed electrode. Thereby, a current path become short, electrical resistance is decreased so that electrical power loss, and heat generation is proportionally reduced and results in a switchgear to be miniaturized. Thus, conventionally, malfunctions in a vacuum switch with electricity made to flow to an external power source and to a load via a rod from a contacting movable electrode and the back of a fixed electrode so that current path is lengthened, the electrical resistance becomes large, and electrical power loss is large are resolved. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
