Abstract
The utility model provides a pneumatic fling-cut switch in a novel high voltage and large current test circuit. The device is composed of a bottom frame, a cylinder, dynamic contacts, static contacts, copper bars, a lamination plate and other components. Each static contact in four static contacts is composed of four pairs of clamped contacts. A bolt is used to adjust the pressure of reeds on both sides of the contacts to increase the ability to contact the dynamic contacts. The contact reliability and the dynamic thermal stability of the pneumatic fling-cut switch are improved. Two dynamic contacts are two special copper bars, and are fixedly arranged on both ends of a telescopic rod of the cylinder through the lamination plate. A cylinder movable rod is controlled to drive the dynamic contacts to move up and down and to be reliably connected with the corresponding static contacts. The dynamic contacts stay at specified opening and closing positions, and fling-cut is realized.
