Patent number: 10134548Abstract: The present disclosure relates to a vacuum interrupter that is installed within a vacuum circuit breaker to break a circuit. The vacuum interrupter includes an insulated container, a seal cup, a fixing electrode, a diaphragm, and a movable electrode. The insulated container is formed in a cylindrical form. The seal cup is installed on an upper end of the insulated container. The fixing electrode includes a fixing shaft and a fixing contact member installed on the other end of the fixing shaft. The diaphragm is installed on a lower end of the insulated container. The movable electrode includes a movable shaft having one end fixed to the diaphragm and the other end disposed within the insulated container and formed to be linearly movable, and a movable contact member installed on the other end of the movable shaft to be selectively contacted to the fixing contact member.Type: GrantFiled: April 21, 2017Date of Patent: November 20, 2018Assignee: LSIS CO., LTD.Inventor: Jae-Seop Ryu

Patent number: 9496106Abstract: Disclosed are an electrode assembly and a vacuum interrupter including the same. The electrode assembly is provided in an insulating vessel which is in a vacuum state, and switches a main circuit. The electrode assembly includes a first electrode plate, a second electrode, a coil conductor, a first conductor, and a second conductor. The coil conductor induces a flow of a current in a first direction and a second direction between the other side of the first conductor connecting pin and the one side of the second conductor connecting pin, and the first direction and the second direction are mutually opposite circumference directions. Accordingly, an arc gas is effectively spread by using mutually opposite flows of currents in a circumference direction, thereby enhancing break performance.Type: GrantFiled: July 23, 2014Date of Patent: November 15, 2016Assignee: LSIS CO., LTD.Inventor: Jae Seop Ryu

Patent number: 9040862Abstract: An electrode assembly for a vacuum interrupter is configured such that supporting members can support most of a contact electrode plate and a supporting electrode plate in an axial direction with coil conductors interposed therebetween. Accordingly, an impact generated between electrode assemblies upon a closing operation of the vacuum interrupter may be evenly distributed onto the supporting members, which may result in preventing each of the electrode plates and the coil conductors from being deformed. Also, the supporting members are inserted into the electrode plates and the coil conductors, thereby effectively preventing a current from flowing via the supporting members. In addition, the supporting member may be wide and large so as to simplify an assembly operation and reduce an assembly time.Type: GrantFiled: June 19, 2012Date of Patent: May 26, 2015Assignee: LSIS Co., Ltd.Inventor: Jae Seop Ryu

Patent number: 8698034Abstract: A vacuum interrupter is provided. As a main shield and sub shields are installed in an overlapping manner, an equipotential distribution can be mitigated and thusly a dielectric strength can be enhanced. Also, as a curved portion is formed at each end of the shields, concentration of an electric field at an end of each shield can be prevented and accordingly an electric field value can be lowered. Consequently, the dielectric strength can be remarkably enhanced, resulting in an effective prevention of a dielectric breakdown.Type: GrantFiled: May 4, 2011Date of Patent: April 15, 2014Assignee: LSIS Co., Ltd.Inventor: Jae Seop Ryu
