Patent number: 9953779Abstract: A bypass switch includes: a casing; a vacuum interrupter disposed inside the casing, the vacuum interrupter being disposed such that a movable contact is movable to a fixed contact; a first fixing bus-bar fixed to the casing; a second fixing bus-bar fixed to the casing to be spaced apart from the first fixing bus-bar; a moving pusher connected to the movable contact; a drive source installed in the casing, the drive source pushing the moving pusher to a position at which the movable contact and the fixed contact are contacted with each other; and a multi-contactor disposed to be contacted with the moving pusher. Accordingly, the moving pusher can rapidly contact the movable contact with the fixed contact. Further, the moving pusher can be moved with a small external force. Thus, it is possible to minimize the size of the drive source and the power used in the drive source.Type: GrantFiled: August 18, 2016Date of Patent: April 24, 2018Assignee: LSIS CO., LTD.Inventor: Teag Sun Jung

Patent number: 9500696Abstract: Provided is a synthetic test circuit for synthetic-testing a thyristor valve in high voltage direct current (HVDC). A resonant circuit applies forward DC current, a reverse DC voltage, and a forward DC voltage to synthetic-test the thyristor valve. A current generation unit generates DC current that is above a reference current value to supply the generated DC current into the resonant circuit. A voltage generates unit generating a DC voltage that is above a reference voltage value to supply the generated DC voltage into the resonant circuit. The resonant circuit includes a charging auxiliary valve for charging a gate driver of the thyristor valve.Type: GrantFiled: July 3, 2014Date of Patent: November 22, 2016Assignee: LSIS CO., LTD.Inventors: Jun Bum Kwon, Teag Sun Jung, Seung Taek Baek, Wook Hwa Lee, Yong Ho Chung
