Effects of the present invention configured as described above are as follows.

Currently, the state of FIG. 2 is a state in which the circuit is tripped (opened), and the movable contact rod 2 and the fixed contact rod 3 in the automatic opening and closing body ASFS of FIG.

In the above state, it demonstrates from the case where the movable contact rod 2 and the fixed contact rod 3 are connected, ie, close.

Pulling and releasing the close lever 16, the pin 15 ′ of the upper end of the lever 16 is guided along the guide groove 17 ′ formed in the guide fixture 17 and descends downwardly, between the connecting rods 14. And 15 are moved as shown in the fifth illustration so that the operation 12 is also moved.

Accordingly, the first stopper 11 connected by the pin 13 to the lower bent portion between the operation 12 is rotated as shown in FIG. 6, wherein the bent portion 11 of the first stopper 11 is locked by the lock gear ( The lock gear 10 is rotated by one pitch while the tooth groove 10 'is positioned at an arbitrary tooth groove 10' and the tooth groove 10 'of the other lock gear 10 is rotated at the same time. The reverse rotation stop 55, which was located, is also retracted while pressing the spring 55 'by the tooth groove 10' surface as the lock gear 10 rotates.

At the same time, the support spring 38, which is installed between the bolt 36 on the upper end of the operation 12 and the upper support rods 37 on both sides, is shot in response to the movement of the operation 12, and then the closing lever 16 As soon as the position is released, the operation section 12 is returned to its original position. Accordingly, the first stopper 11 is also displaced, thereby bending the first stopper 11 to the next tooth groove 10 'of the lock gear 10. 11 ') is positioned as it is, and the lever 16 is raised along the guide fixture 17 at the same time.

Accordingly, once the close lever 16 is pulled out and released, the lock gear 10 rotates one pitch.

The lock gear 10, the number of tooth grooves 10 'is formed in the figure 8, but may be formed in an appropriate number in proportion to the spiral spring (8) to be described later.

However, when the lock gear 10 is rotated, the spring housing 9 fixed by the lock gear 10 and the bolt 34 is also rotated as shown in FIG. 5, and the two helical springs 9 in the spring housing 9 are rotated. 8) is reduced by the rotation of the lock gear 10 and the spring housing (9).

That is, when the spring housing 9 is rotated, the hook 8 "of the spring 8 is welded to the engaging protrusion 9 'in the housing 9, and the inner end 8' of the spring 8 is welded. Since the spring (8) is wound because it is fitted to the central shaft (7), at this time, the central shaft (7) on the protruding jaw (25 ') of the pivoting hole (25) fixed as a fixing key (58) ) Is caught (11) and the central axis (7) is not rotated. (See Fig. 4)

As described above, when the close lever 16 is held and released, the lock gear 10 and the spring housing 9 are rotated while the central shaft 7 is fixed, and the two springs 8 are rotated. You will be rotated by one.

Pulling and releasing the closing lever 16 as many times as described above, the spring (8) is further wound by that, the lock gear 10 and the spring housing (9) is also rotated, any of the spring housing (9) According to the rotation, the actuating key 30, which is fixed on the one side of the spring housing 9, is connected to the inner surface of the front plate 5 by a pin 29, as shown in FIG. The pin 29 moves around the pin 46 along the long hole 47 formed in the front plate 5 by pushing.

Therefore, as the pin 29 moves, the interlocking section 28 is retracted at the same time, and the central shaft 7 fixed to the pivoting hole 25 is removed from the protruding jaw 25 'of the pivoting hole 25. As shown in FIG. 4, the operating arm 45 is moved to the right while the operating arm 45 is moved to the right, and the movable contact rod 2 is connected to the fixed focusing rod 3 by rotating the driving shaft S. .

In the above, the protruding jaw 25 'of the pivoting hole 25 is caught by the protruding jaw 31 "at one end of the deburred key 3. In this case, the wound spring 8 is centered as described above. It is raised by the rotation of the shaft (7), the rotational hole 25 is rotated about 90 degrees, so that the wound spring (8) is about half of the short state is reduced.

As described above, the rotating hole 25 is rotated so that the fixing protrusion 9 "" of the spring housing 9 pushes the operation key 30, and at the one side bolt 9 "" of the spring housing 9; The fixed pusher 44 is also rotated in response to the start of the spring housing 9, and the taper portion of the pusher 44 is pressed against one side of the driving member 24 (see FIG. 5).

Therefore, the pressing hole 44 is raised at the other end of the driving section 24 under the safe operating section 23 with respect to the pin 43 to raise the safe operating section 23.

Then, the pin 23 ″ of the pre-operational operation 23 is raised along the groove 39 ′ of the guide rail 39 so that the spring 41 is shot as shown in FIG. 7, and the taper of the safety operation 23 is secured. It passes through the dolsulpin 11 "of the 1st stopper 11 which hanged on the part 23 '(refer FIG. 7 and FIG. 8).

Therefore, the dossier pin 11 "is out of the taper portion 23 'of the small farm 23, so that the spring 35 which is installed on the dolphine pin 11" of the first stopper 11 as shown in FIG. The bent portion 11 'of the first stopper 11 is separated from the tooth groove 10' of the lock gear 10 while being shot.

Then, when the safe operation section 23 is raised as described above, while pulling (19) and (20) connected by the guide section 21 in the guide box 22 that was suppressed by the spring 22 ' While being shot, as shown in FIG. 7, one end of the interlocking portion 21 is positioned below one side of the safe operation 23 so that the safe operation 23 is locked without descending downward.

As described above, the overall operation is performed by pulling the close lever 16 8 (when there are eight teeth 16 of the lock gear 10) in the accompanying drawings, that is, the spring housing 9 ) The fixed projection 9 "" on one side pushes the operation key 30, and the pressing hole 44 presses the other end of the drive shaft 24, and the state that the spring 8 is wound about half way is released. to be.

Then, the pull lever 16 is pulled eight times and then released, and the state returns to its original position as shown in FIG. 3, and the stone jaw 25` of the pivoting hole 25 is caught by the stone jaw 31` of the lever-type key 31. It becomes a state and it becomes a state in which the trunk | drum 28 was extended to one side surface in the rotational opening 25. As shown in FIG.

Then, even if the operator or the line pulls the closing lever 16 for the close without knowing the state in which the operation main body is closed in the above state, the bent portion 11 'of the first stopper 11 is held by the lock gear 10. Operation is disabled because it is out of the tooth groove.

In the state in which the above state tripped, the movable contact rod 2 and the fixed contact rod 3 were connected to a closed state.

Next, when an abnormality occurs in the customer side of the distribution line, the trip of the opening / closing operation main body, that is, the opening operation will be described.

First, when the current flows through the solenoid Sol, or when the operator pulls the lever 51 for the trip, the solenoid Sol is tripped while the operation 52 descends downward.

That is, when a current flows in the solenoid Sol or when the operator pulls and releases the trip lever 51 manually, the operation period 52 comes down and is returned to its original position by the spring 56. As shown in the figure, when the trip lever 51 comes down, the trip key 33 connected to the lever 51 is driven with the pin 33 " as the center, and pushes one end of the latch 32 to the spring 50. ), The lever-type key 31, which was caught on the end of the hook 32, is held in the hemispherical support bar 48 under the hemispherical pin 32 'according to the movement of the hook 32. Rotate the spring (49) around the center to move away from the stone step (25 ') of the rotating hole 25, which is hanging on the stone step (31 ") of the lever-type key 31, the rotating hole 25 is in the original position As shown in FIG. 3, the interdental space 28 is hung on the stone step 25 ′.

Thus, the spring 8 is completely flipped again in the half unwinded state as much as the spring 8 is wound.

At this time, the jaw 31 "of the lever-type key 31 is deviated from the jaw 25 'of the pivoting hole 25, and then is repositioned by the spring 49 to be caught by the stopping rod 48, 32 is also in the original position by the spring 50, the jaw (32 ") thereof is caught in the lever type 31.

Of course, the trip container 33 also returns to its original position as the trip lever 51 rises.

In the above description, at the moment of pulling the trip lever 51, the connecting rods 19 and 20 are also pulled along one side of the tripping operation 18, so that the spring 22 'in the locking box 22 is pulled out. The interlocking section 21 is retracted while suppressing the interlocking section 21, which has been shot down on one side of the safe operating section 23, is released, and the safe operating section 23 is lowered by the spring 41. 44 is in a state deviated from one side upward of the drive rod 24, so that the safe operation 23 is in the original position while pressing the other end of the drive rod 24.

At this time, the first stopper 11 and the protrusion 11 of the first stopper 11 are positioned above the tapered portion 23 'side of the safety operation 23, and the first stopper 11 is recirculated by the spring 35. Upon return, the bent portion 11 thereof is positioned in any tooth groove 10 'of the lock gear 10.

As described above, the operation arm 45 is also in the original position, and the movable flat bar 2 is separated from the fixed contact bar 3.

As described above, the present invention makes it easy to close the circuit by winding and loosening the spring, and to trip by releasing and turning the locked rotational hole by the intermittent operation between the tricks. It is characterized by having a safety device that prevents it from operating even if it is operated. Particularly, it is useful for an automatic device for failure section because the operation operation is sure.
