Then, the operation of extracting the handle 204 is continued, and after the extraction of the circuit breaker body 100 is performed, the track detecting link 51 is maintained in the clockwise direction as shown in the first figure, so the closing bar is closed. The 27-series is maintained in a state of being rotated clockwise, and is in a state in which the energy storage of the closed-circuit spring 禁止 is prohibited. According to the present embodiment, it is detected that the circuit breaker main body 1 is extracted from the extraction frame 200, and a position detecting rail 202 for automatically releasing the energy storage closed-circuit spring 17 is provided on the side surface of the circuit breaker main body 1? Therefore, after the circuit breaker body 1 is pulled out from the drawing frame 200, even if it is placed directly on the ground, the deformation of the road detecting device is not included. Further, since the closed spring 17 cannot store energy when the position detecting lane 202 is not detected, the closed magazine cannot store energy when it is not inserted into the drawing frame, and therefore it is safe. Further, the closing plate 56 fixed to the closing bar 27 is rotated by the rail detecting link 51 - the shaft 53 - the interlocking plate 54 - > pressing the link 55, thereby driving the closing rod 27 to release the closing spring 17 Therefore, after closing the rod 27, the existing mechanism can be used, and the automatic energy release mechanism can be installed after the local modification, and it is not necessary to return to the workshop for modification or replace each body', and the modification time can be shortened or modified. The cost is reduced. Further, in the drawing frame 200, the position detecting track 2〇2' is provided on the side of the breaking circuit 201249038, and the track detecting link 51 is disposed in such a manner as to be movable in accordance with the shape of the position detecting way 202, even in the closed-circuit spring 17 : v The state of energy storage, because the circuit breaker body 17 is released when the circuit breaker body 1 is pulled out from the extraction frame 200, so that the closed state spring 17 of the energy storage state can be avoided after the circuit breaker body 100 is pulled out. Release the energy and avoid checking the horror or accident of the repairer. Further, since the circuit breaker body 1 after the extraction is in the state of release of the closed circuit spring 17, it is possible to prevent the operator 13 other than the inspection repairer from operating the handle spring 13 to cause the energy storage of the closed spring 17. Further, in the present embodiment, the position detecting track 2 0 2 constituting the automatic release mechanism is located on the inner side of the side of the drawing frame 200, but when it is provided on the inner side of the upper side of the drawing frame, the track may be The detecting link 51 is disposed above the corresponding circuit breaker body. Further, in the present embodiment, the track detecting link 51 is provided with the position detecting track 202 for detecting the extracted state of the main body of the circuit breaker, but the track detecting link 51 can directly detect the drawing frame 200. (Embodiment 2) In the first embodiment, the embodiment in which the circuit breaker main body 100 after the extraction is not possible to store the energy of the closed spring 17 is described. However, depending on the condition of the repair, it may be assumed that it is necessary to be in the circuit breaker body 100. The state in which the closed spring 17 is stored after being extracted. In the second embodiment below, the closed spring 17 can be stored even after the extraction. Figure 11 is a side cross-sectional view showing the automatic 323712 17 201249038 'release mechanism of the closed-circuit spring at a position corresponding to the third figure, and the 12th ® is a side cross-sectional view of the automatic release energy v' mechanism of the closed-circuit elastic, and In the state in which the track detecting link is in the vicinity of the position at which the closing spring is released, FIG. 13 is a perspective view showing the automatic releasing mechanism of the closed spring in the position corresponding to the first figure. As shown in Fig. 11, the obstruction detecting link 51 is disposed on the lower side of the position detecting rail 202, and the position detecting rail 202 is provided with a convex portion 202a having a curved shape which is partially directed downward of the sheet. Further, the interlocking plate 54 and the track detecting link 51 are rotated by the counterclockwise rotation of the paper toward the upper side of the paper by pressing the interlocking plate 54 downward to the upper link 55. The other structure is the same as that of the first embodiment, and thus the description thereof will be omitted. Further, the convex portion 2〇2a may have another shape such as a semicircular shape, and the "extraction detecting portion" described in the patent application is the convex portion 202a. At this time, when the handle 204 is inserted from the insertion hole 14 and the circuit breaker body 1 is pulled out from the extraction frame 200, the track detection link 51 moves to the position detection track as shown in FIG. Under 202. When the circuit breaker body 1 is pulled out from the extraction frame 200 to a predetermined position, the track detecting link 51 abuts on the convex portion 2〇2a of the curved shape or the semicircular shape of the position detecting track 202, and along The shape of the bit ί detecting track 202 is rotated clockwise with the axis 53 as the axis. As shown in Fig. 12, when the track detecting link 51 reaches the vicinity of the apex of the curved portion of the position detecting track 202 or the convex portion such as a semicircular shape and rotates clockwise, similarly to the above-described embodiment, each mechanism In the same manner as when the ON button 11 of Fig. 1 is pressed, the closed spring 17 is released. At this time, the movable contact 43 does not operate, and is the same as the spring π-released only by the closed circuit 18 323712 201249038. Then, the operation of extracting the handle 204 is continued, and when the operation of the circuit breaker body 1 is continued, the track detecting link 51 is as shown in Fig. 13, because it is moved to the position detecting track. a curved portion of 202 or a convex portion such as a semi-HI shape, so that it returns to the state of turning in the opposite direction #f*, and the closing rod 27 returns to a state in which it can be rotated in the counterclockwise direction. Therefore, it becomes a closed-circuit spring to store energy again. State. According to the present embodiment, since the circuit breaker main body 100' is extracted from the drawing frame 200 and the position detecting rail 202 for automatically releasing the energy storage closed-circuit spring 17 is provided on the side of the circuit breaker main body 1' After detecting that the circuit breaker body 100 is withdrawn from the extraction frame 200, even if it is placed directly on the ground, there is no possibility that the track detecting device is deformed. In addition, since the closed-circuit spring is released only when the position detecting track is detected based on the shape of the convex portion of the position detecting track 202, the circuit breaker body is not detected even if the circuit breaker body is lowered from the drawing frame 2 at the time of inspection. The position detecting track, so the closed-circuit spring 17 can store energy and does not hinder the maintenance during maintenance and inspection. Further, the closing plate 56' fixed to the closing bar 27 is rotated by the track detecting link 51-shaft 53-linking plate 54-pressing the catch 55, thereby driving the closing bar 27 to release the closing spring 17, so After closing the rod 27, the existing mechanism can be used, and the automatic energy release mechanism can be installed after the local modification. It does not need to be transported back to the workshop for modification or replacement for each body, and the reduction time or the modification cost can be achieved. Cost reduction. In addition, the circuit breaker body 1 after the extraction is made up of the test operation, etc. 19 323712 201249038 'In order to save the closed-circuit magazine 17 , the repairer can check the repairer for inspection or the like as needed. After the body 100 is withdrawn, the closed circuit spring 17 is stored. Further, in the first embodiment and the second embodiment described above, the mechanism of the position detecting cue 2 0 2 and the track detecting link 51 is provided on the side of the circuit breaker main body 100, but even in such a mechanism In the case of being disposed above the circuit breaker body 100, when the extracted circuit breaker body 100 is directly placed on the ground, the mechanism for automatically detecting the track detection link 51 for the closed-circuit magazine 17 is not deformed, etc. Thereafter, this point is the same as that described in the above embodiment.
