More specifically, the insulated rod 260 is a power transmission rod which is a movable electrode side drive shaft which transmits the power of the linearly moving output shaft 13 as the opening and closing driving force of the contact switchgear of the ultra-high voltage switchgear, and is insulated. The rod 260 is drive-connected to the output shaft 13 via a rotating lever 20. The rotation lever 20 is rotatably supported by the rotation support shaft 21 which is positionally fixed to support rotation. Therefore, the power of the output shaft 13 which moves linearly is transmitted to the insulated rod 260 via the rotating lever 20. In more detail, when the output shaft 13 is linearly moved to the right as shown in FIG. 1 (in FIG. 5, as the output shaft 13 is linearly moved to the left), a rotary lever having one end connected to the output shaft 13 ( 20 rotates in a clockwise direction about the rotation support shaft 21, so that the insulating rod 260 connected to the other end of the rotation lever 20 is linearly moved to the left as shown by the dotted arrow in FIG. When the output shaft 13 is linearly moved to the left as shown in FIG. 2, the rotary lever 20, one end of which is connected to the output shaft 13, rotates counterclockwise about the rotary support shaft 21 and thus rotates. The insulating rod 260 connected to the other end of the lever 20 is linearly moved to the right as shown by the arrow of FIG. 2. In FIG. 2, upper and lower arrows of the first arc contact 210 indicate a direction in which SOHO is injected in the compression chamber 240, and dotted lines around the nozzle 230 indicate arcs.

The first arc contact 210, the cylinder rod 250, and the first main contact 310 are composed of electrical conductors, and the cylinder rod 250 is connected to the first main contact 310 and an electrical conductor connecting member (not shown). By electrical and mechanical connection. Therefore, as the cylinder rod 250 moves linearly back and forth by the driving force transmitted through the insulating rod 260, the first main contact 310 connected to the cylinder rod 250 is also straight in the same direction. Will move. Further, the first main contact 310 is in contact with the first fixed cylinder 200 made of an electrical conductor and electrically connected to each other. The first fixed cylinder 200 may be connected to the power supply side or the load side of the power system through connection means formed of a conductive medium such as a busbar and a power cable (not shown). Therefore, the first arc contactor 210 is electrically connected to the cylinder rod 250, the first main contactor 310, the first fixed cylinder 200, and the power supply side or the load side of the power system.

The second arc contact 110 is provided to face the first arc contact 210, and is electrically connected to any one of a power system circuit of a power supply and a load side. In other words, when the first arc contact 210 is connected to the power side of the power system circuit, the second arc contact 110 is connected to the load side of the power system circuit, and the first arc contact 210 is connected to the power side of the power system circuit. When connected to the load side, the second arc contact 110 is connected to the power supply side of the power system circuit to form a power system circuit between the power supply side and the load side. In order to close or open the circuit of the power system, the second arc contact 110 is in contact with or separated from the first arc contact 210. According to an embodiment, the second arc contactor 110 has a fixed installation, and the first arc contactor 210 rotates the linear force from the output shaft 13 of the squeeze control device according to the present invention. , The power supply circuit is separated from the closed position or the second arc contactor 110 received through the insulating rod 260 and the cylinder rod 250 to make contact with the second arc contactor 110 to make a closed circuit. Linear movement to the open position to open is possible.

The fixed piston 220 is fixedly installed in the first fixed cylinder 200 and forms a compression chamber 240 together with the linearly movable first main contactor 310 and the cylinder rod 250. There is an arc extinguishing gas for arc arcing in the compression chamber 240.

At the distal end of the first main contact 310, the nozzle 230 is fixedly installed by welding or the like, so that the compression chamber during operation to the open position in which the first arc contact 210 is separated from the second arc contact 110 is performed. The arc extinguishing gas in 240 is sprayed toward the second arc contact 110 to rapidly extinguish the arc generated between the first arc contact 210 and the second arc contact 110 during the open position operation.

On the other hand, with reference to Figures 1 to 6 will be described the operation of the ultra-high pressure switch actuator operation apparatus and ultra-high pressure switch comprising the same according to the present invention configured as described above.

Push to push to the left in FIG. 3.

The shift in the left direction as shown in FIG. 5 from the position of FIG. 3 of the bunch of balls 6 causes a leftward movement of the output shaft 13 in contact with the bunch of balls 6, so that the output shaft 13 is right in FIG. The rotation lever 20 rotates in the clockwise direction because it moves in the direction. Therefore, in FIG. 1, the insulating rod 26 having one end connected to the rotary lever 20 moves linearly to the left in the drawing, and the cylinder rod 250 connected to one end of the insulating rod 26 is linearly moved to the left. The first arc contactor 210 attached to the first contactor 210 moves to the left side and contacts the second arc contactor 110 to make a closed circuit of the power system so that a current can flow from the power supply side to the load side. This position is also referred to as the closing position in the ultrahigh pressure switch.

When the bundle of balls 6 moves to the left in a straight line, as shown in FIG. 4, the large diameter portion 5a of the bolt 5 pushes the charge 9 into the chamber 2 so that the charge 9 is loaded in the chamber 2. It will be in the state shown in FIG.

Thereafter, the striking body 15 is hit by the spring and the lever or the link by mechanical drive or by the electric drive by an electric motor or solenoid valve, that is, as shown in FIG. When driving to the position moved to the left as described above to hit the trigger pin 7, the trigger pin 7 hits the rear surface of the charge 9 loaded in the chamber 2 to cause a trigger.

The charge 9 explodes into the combustion chamber 3 and the explosive gas moves to the gas cylinder 4 to push the piston 8 to the explosion pressure, so that the piston 8 is shown in the state as shown in FIG. It instantaneously moves to the right, so that the ball bundle 6 connected with the piston 8 also momentarily moves to the right through the connection extension 6b, and the output shaft 13 connected with the ball bundle 6 is also together. Move to the right. In addition, at this time, as the bunch of hexes 6 moves to the right side, as shown in FIG. 3, the ends of the stoppers 12 are latched by the latching grooves 6a1 provided on the lower surface of the cage supporting part 6a. ) Is positioned at the restraint position and the first spring 11 is compressed by the chuck bundle 6 moved to the right to make the elastic energy condensed.

As such, when the output shaft 13 is moved to the right as shown in FIG. 3, the output shaft 13 is moved to the left in FIG. 2, and the rotary lever 20 is moved in accordance with the leftward movement of the output shaft 13. ) Rotates counterclockwise. Therefore, in FIG. 2, the insulating rod 26 having one end connected to the rotary lever 20 is linearly moved to the right in the drawing, and the cylinder rod 250 having one end connected to the insulating rod 26 is linearly moved to the right. The first arc contactor 210 attached to the first arc contactor 210 moves to the right and is separated from the second arc contactor 110 to be countered to make the circuit of the power system an open circuit (blocking) so that the current is cut off from the power supply side to the load side. The position of this ultrahigh pressure switch is a so-called blocking position (open position).
