Abstract
A high speed switch comprises an interrupter unit connected to a main circuit and including a movable electrode and a driving electrode for opening or closing the main circuit; a driving unit including a repulsion coil for providing a driving force for moving the movable electrode of the interrupter unit, and a repulsion plate disposed opposite to the repulsion coil; a guide rod part connecting the movable electrode of the interrupter unit to the repulsion plate, having a latch groove formed therein, and reciprocating vertically according to movements of the repulsion plate; and a state-holding unit for regulating the movement of the guide rod part, wherein the state-holding unit comprises: a latch pin; a latch elastic member; and a latch coil.
Claims13
A high-speed switch comprising:
- current interrupting means connected to a main circuit, wherein the current interrupting means includes a movable electrode and a fixed electrode for opening and closing the main circuit;
- a driving assembly including:
- a repulsive coil for providing a driving force to move the movable electrode of the current interrupting means, and a repulsive plate facing the repulsive coil;
- a guide rod assembly for connecting the movable electrode of the current interrupting means to the repulsive plate, wherein the guide rod assembly reciprocates vertically together with a vertical movement of the repulsive plate;
- and
- a state-maintaining assembly configured to control a movement of the guide rod assembly,
- wherein a latch groove is defined in the guide rod assembly,
- wherein the state-maintaining assembly includes:
- a latch pin wherein an end of the latch pin corresponds to the latch groove;
- a latch elastic member for pressing the latch pin toward the guide rod assembly such that the end of the latch pin is inserted into the latch groove;
- and
- a latch coil wound around an outer circumferential face of the latch pin to provide a driving force for releasing the latch pin from the latch groove.
A high-speed switch comprising:
- current interrupting means connected to a main circuit, wherein the current interrupting means includes a movable electrode and a fixed electrode for opening and closing the main circuit;
- a driving assembly including:
- a repulsive coil for providing a driving force to move the movable electrode of the current interrupting means, and a repulsive plate facing the repulsive coil;
- a seal rod connected to the movable electrode and the repulsive plate;
- and
- a state-maintaining assembly configured to control a movement of a guide rod assembly,
- wherein the seal rod is connected to the movable electrode,
- wherein the seal rod has one end connected to an insulating rod and another end connected to a latch rod, and
- wherein the latch rod has one end connected to the seal rod and another end coupled to the repulsive plate, wherein a latch groove is defined in the latch rod.
