Description

Operating mechanism of switch interlocking disconnector {OPERATING DEVICE OF SWITCH INTERLOCKING WITH DISCONNECTOR}

The present invention relates to an operating mechanism of a switch, and more particularly, to an operating mechanism of a switch interlocked with a disconnector.

VI (Vacuum Interrupter) applied to the switchgear's main circuit causes insulation breakdown due to a decrease in internal vacuum level, and accidents occur due to induced voltage and charging current that occur between VI (Vacuum Interrupter) poles when the main circuit is opened. To prevent this, a switch with a built-in disconnector capable of opening and closing the charging current is being developed.

However, the conventional switch with a built-in disconnector has a problem in that the size of the switch is increased because separate operating mechanisms are provided to operate the disconnector and the main circuit.

In addition, the conventional switch with a built-in disconnector should operate the operating mechanism after recognizing the input sequence or opening sequence of the disconnector and the main circuit unit. For example, when the switch is closed for opening and closing of the charging current, when the disconnector and main circuit are closed, if the disconnector is closed after the main circuit is closed, an arc is generated in the conducting part of the disconnector and a ground fault occurs, and when the switch is opened However, if the disconnector is opened first, the current-carrying part of the disconnector opens and closes the load, resulting in damage to the current-carrying part.

In this way, when each separate operating mechanism is provided to operate the disconnector and the main circuit, there is a problem that an accident may occur due to an operator's mistake or an external factor.

When the first disconnector operating link 200 moves to one side, the disconnector operating shaft 230 can rotate clockwise, and when the disconnector operating shaft 230 rotates clockwise, the disconnector operating spring 250 At the same time as this is compressed, the disconnector action shaft 231 connected to the disconnector action shaft 230 rotates clockwise so that the disconnector rod hinge 240 fixedly coupled to the end of the disconnector action shaft 231 rotates clockwise. there is. Accordingly, the disconnector rod 241 connected to the disconnector rod hinge 240 may be input.

In addition, the disconnector hinge rod 212 can press and rotate the first main circuit latch body 321 by moving to the upper portion of the first slot 11, and the first main circuit latch body 321 rotates By doing so, the first latch link 322 is moved in the rotational direction of the first main circuit latch body 321, and the second latch link 323 connected to the other end of the first latch link 322 is rotated to The latch 324 can be rotated. As a result, the fixed state of the main circuit hinge 310 can be released, and the elastic force of the closing and opening spring 400 tensioned by the movement of the disconnector hinge rod 212 to the upper part of the first slot 11 is reduced. Through this, the main circuit hinge rod 311 can move to the top of the second slot 12 . At this time, as the main circuit hinge rod 311 moves to the upper part of the second slot 12, the main circuit rod 330 to which the main circuit hinge rod 311 is connected can be put in, and at the same time, the main circuit hinge The pressure applied to the first disconnector latch 260 by the rod 311 is released so that the first disconnector operation latch 260 can rotate counterclockwise. When the first disconnector operating latch 260 rotates clockwise, the second disconnector operating link 270 can move to one side, whereby the second disconnector latch 280 rotates clockwise. The motion shaft 230 may be fixed. By fixing the disconnector operating shaft 230 in a rotated state, the disconnector operating spring 250 can be maintained in a compressed state.

Hereinafter, with reference to FIG. 7, the sequence of opening the disconnector rod and the main circuit rod of the operating mechanism of the switch interlocked with the disconnector according to a preferred embodiment of the present invention will be described in detail. Hereinafter, descriptions of conventionally known matters are omitted or simplified to clarify the gist of the present invention.

Referring to FIG. 7 , the operating mechanism 1 of the switch interlocked with the disconnector according to the preferred embodiment of the present invention is driven by the motor 110 receiving the open command, and the first motor 110 provided at one end. The spur gear 111 can be rotated counterclockwise, and the first spur gear 111 is engaged with the second spur gear 122 provided at the other end of the motor crankshaft 121 connected to the motor crank 120. The second spur gear 122 may be rotated clockwise. When the second spur gear 122 rotates clockwise, the motor crankshaft 121 can rotate in the same direction, whereby the motor crank 120 rotated at a predetermined angle can rotate back to its original position. there is.

The motor link 130 may be moved to the other side by the rotation of the motor crank 120 to the original position, and the motor crank hinge connected to the other end of the motor link 130 by the motor link 130 being moved to the other side ( 140) may rotate counterclockwise. When the motor crank hinge 140 rotates counterclockwise, the disconnector hinge shaft 211 can rotate counterclockwise, whereby the disconnector hinge 210 can rotate counterclockwise. When the disconnector hinge 210 rotates counterclockwise, the disconnector hinge rod 212 may move to the lower portion of the first slot 11 . By moving the disconnector hinge rod 212 to the lower part of the first slot 11, the second main circuit latch body 341 can be pressed and rotated, and the second main circuit latch body 341 rotates by moving the second latch link 342 in the rotational direction of the second main circuit latch body 341, and rotating the fourth latch link 343 connected to the other end of the third latch link 342 to secure the second latch ( 344) can be rotated. As a result, the fixed state of the main circuit hinge 310 can be released, and the elastic force of the closing and opening spring 400 tensioned by the movement of the disconnector hinge rod 212 to the lower part of the first slot 11 Through this, the main circuit hinge rod 311 can move to the lower part of the second slot 12 . At this time, as the main circuit hinge rod 311 moves to the lower part of the second slot 12, the main circuit rod 330 to which the main circuit hinge rod 311 is connected can be opened, and at the same time, the main circuit hinge The rod 311 presses the first disconnector latch 260 so that the first disconnector operation latch 260 can rotate clockwise.

When the first disconnector operation latch 260 rotates clockwise, the second disconnector operation link 270 can move to the other side, whereby the second disconnector latch 280 rotates clockwise. The motion shaft 230 may be unfixed. Accordingly, the disconnector operating shaft 230 can be rotated counterclockwise by the force of the compressed disconnector operating spring 250 returning to the original position, and the disconnector operating shaft 230 rotates counterclockwise. The disconnector action shaft 231 connected to the disconnector action shaft 230 rotates counterclockwise so that the disconnector rod hinge 240 fixedly coupled to the end of the disconnector action shaft 231 rotates counterclockwise. Accordingly, the disconnector rod 241 connected to the disconnector rod hinge 240 may be opened.
