[ The rotary lever 20 is rotatably supported by a rotary support shaft 21 which is positionally fixed to support the rotary member. Thus, the power of the linearly moving output shaft 13 is transmitted to the insulated rod 260 via the rotating lever 20. [ More specifically, when the output shaft 13 linearly moves to the right as shown in Fig. 1 (as the output shaft 13 moves linearly to the left in Fig. 5), one end of the output shaft 13 is connected to the output shaft 13 20 rotates clockwise about the rotation support shaft 21 and thus the insulation rod 260 connected to the other end of the rotation lever 20 moves linearly to the left as indicated by the dotted arrow in FIG. 2, the rotary lever 20 having one end connected to the output shaft 13 rotates counterclockwise about the rotary support shaft 21 and is thus rotated The insulating rod 260 connected to the other end of the lever 20 is moved linearly to the right as shown by the arrow in Fig. 2, the upper and lower arrows of the first arc contactor 210 indicate the direction in which the SOH gas is injected in the compression chamber 240, and the dotted lines around the nozzle 230 indicate the arc.

More specifically, the first arc contact 210 is connected to the insulating rod 260 through a cylinder rod 250 attached to the tip of the cylinder rod 250 and connected to the insulating rod 260. The first arc contact 210 and the cylinder rod 250 and the first main contact 310 are formed of an electrical conductor and the cylinder rod 250 is connected to the first main contact 310 and an electrical conductor connecting member And are electrically and mechanically connected. The first main contactor 310 connected to the cylinder rod 250 also moves linearly in the same direction as the cylinder rod 250 mechanically moves linearly back and forth by the driving force transmitted through the insulating rod 260. [ . Also, the first main contact 310 contacts the first fixed cylinder 200 constituted by an electrical conductor and is electrically connected to each other. The first stationary cylinder 200 may be connected to the power or power side of the power system via connection means formed of a conductive medium, such as a busbar and a power cable, not shown. Therefore, the first arc contact 210 is electrically connected to the power source side or the load side of the cylinder rod 250, the first main contactor 310, the first fixed cylinder 200, and the power system.

The second arc contactor 110 is installed opposite to the first arc contactor 210 and is electrically connected to the power system circuit of either the power source or the load side. In other words, when the first arc contact 210 is connected to the power supply 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 system circuit When connected to the load side, the second arc contactor 110 is connected to the power source side of the power system circuit to constitute a power system circuit between the power source side and the load side. The second arc contactor 110 contacts the first arc contactor 210 or separates from the first arc contactor 210 in order to close or open the circuits of the power system. The first arc contactor 210 is connected to the rotary lever 20 via the output shaft 13 of the explosion-proof operation device according to the present invention. The second arc contactor 110 is fixedly installed, The insulation rod 260 and the cylinder rod 250 to be brought into contact with the second arc contact 110 to bring the power system circuit into a closed position or from the second arc contact 110 separated from the power system circuit And is linearly movable to an open position for opening.

The fixed piston 220 is fixed in the first fixed cylinder 200 and forms a compression chamber 240 together with the first main contact 310 and the cylinder rod 250 which are linearly movable. In the compression chamber 240, there is a soot gas for arc extinguishing.

The nozzle 230 is fixed to the tip of the first main contact 310 by welding or the like so that when the first arc contact 210 is separated from the second arc contact 110, So that the SOG gas in the second arc contact 240 is sprayed toward the second arc contactor 110 so that the arc occurring between the first arc contact 210 and the second arc contact 110 during the open position operation is promptly extinguished.
