Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a breaker restoring device by remote control, and more particularly to a breaker restoring device which has a simple structure and can be operated by remote control. is there. 2. Description of the Related Art When a breaker installed in a mountain or other remote place is interrupted by an abnormal current or the like, a breaker restoring device is operated by remote control based on a command signal transmitted from a control circuit, and power is supplied. A breaker restoring device for restoring a normal state is disclosed in Japanese Patent Application Laid-Open No. 2001-1184.
No. 83. As shown in FIG. 6, this prior art breaker restoring device is provided on a side surface of a breaker 5 and has a pair of rotatable switch holding plates 11 attached thereto.
A, 11B are provided. In order to recover the breaker with this breaker recovery device 10,
The switch holding plates 11A and 11B are operated and rotated by remote operation so as to surround the switch 6 of the breaker 5 on both sides, and the switch holding plates 11A and 11B in this state are similarly moved by remote control. As a result, the switch 6 of the cut-off circuit breaker 5 is moved from the cut-off holding position 2A1 to the cut-off holding release position 2A2, and is again inverted to the normal switch position 2A3 to turn on the switch again. It is to be.
In FIG. 6, reference numeral 12 denotes a motor, 13 denotes a switch recovery operation control sensor group, 14 denotes a switch recovery operation control sensor operating piece, and 15 denotes a holding plate opening / closing stop sensor. According to this device, the conventional inefficient work, such as a worker going to a distant site such as a mountain every time to restore a breaker, can be eliminated, and speeding up and labor saving can be achieved. become. In addition, there are many advantages such as the ability to simultaneously cope with restoration of simultaneous multiple interruptions caused by thunderclouds in a short time. [0004] However, this breaker recovery device has a large number of parts and a complicated structure. Therefore, there was a problem that maintenance and inspection were troublesome. Also, in this device, if there is an obstacle to the breaker operation, for example, if the switch holding plate stops while holding the switch lever part of the breaker due to a failure or the like, the worker will turn off the breaker when checking this device. There was a problem that it could not be controlled. SUMMARY OF THE INVENTION The present invention relates to a breaker restoring device which has a simplified structure and does not have any member placed at the switch lever portion of the breaker so as not to hinder inspection. Another object of the present invention is to provide a breaker restoring device which is easy to assemble, has few failures, and can be easily maintained and inspected. According to the present invention, a rotating gear connected to a motor of a breaker restoring device is provided on a side surface of a breaker, and a semi-circular gear is coupled to the rotating gear. Protrusions that press the switch lever of the breaker are provided at both ends in the diametric direction of the breaker, and by rotating the motor of the breaker recovery device, the protrusions provided at the diametric ends of the semicircular gear press the switch lever of the breaker. This is a breaker recovery device in which the switch of the interrupted breaker is turned on again. FIG. 1 is a perspective view of a breaker restoring device according to the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof. 1 to 3, 1 is a general-purpose breaker, and 20 is a breaker recovery device. Reference numeral 2 denotes a switch of the breaker 1. Referring to FIG. 2, when viewed from the front, the center position is the cutoff holding position 2A1, the lower position is the current cutoff holding release position 2A2, and the upper position is the normal fixed position 2A3. 2
0 indicates that it is located at the normal stationary position 2A3. When the breaker 1 shuts off due to overcurrent or the like, the switch moves to the current interruption holding position 2A1. To recover this, the switch 2 is moved to the current interruption holding release position 2A2 located just below, and thereafter the switch 2 moves to the current interruption holding position 2A2. And the switch is returned to the normal-time stationary state 2A3 to recover. This breaker recovery device 20 is provided in parallel with the breaker 1. Breaker recovery device 20
, A motor 22 is provided in a housing 21 and is driven by a driving battery 23. A reduction gear 24 is connected to the motor 22, and a rotation gear 26 is connected to a rotation shaft 25 having a predetermined slow rotation. The rotation gear 26 rotates in the horizontal direction by the rotation of the motor 22. Reference numeral 27 denotes a semicircular gear made of synthetic resin, which is connected to the rotary gear 26 so that the height position thereof is the same as that of the switch 2 of the breaker 1 on the side surface. Reference numeral 28 denotes a rotation shaft of the semicircular gear 27. Protrusions 29A and 29B are provided at the diametric end of the semicircular gear 27. The projections 29A and 29B rotate the rotation shaft 28 of the semicircular gear 27 as a fulcrum, thereby pressing the switch lever 2 of the breaker 1 to open and close the switch. The semi-circular gear 27 is provided with another projection 30A, 30B slightly inside the projection 29A, 29B. This is because the switch 2 is closer to the breaker recovery device 20 depending on the type of the breaker 1. This is another projection that can be used also for. FIG. 4 is a perspective view of the breaker restoring device shown in FIG. 1 with the semicircular gear 27 removed. Limit switches 31A and 31B are provided on the upper surface of the housing 21 of the breaker recovery device. A normal position sensor 32A and a current interruption release position sensor 32B are mounted on the back surface of the semicircular gear 27, and the limit switches 31A and 31B are rotated by rotating the semicircular gear.
Is turned on and off. The recovery of a breaker by remote control using the above-described device is performed as shown in FIGS. That is, FIG. 5A shows that the breaker 1 is in a normal state. In this state, when an abnormal current flows to the breaker 1 and the switch 2 is cut off, the switch 2 moves to the central current cutoff holding position as shown in FIG. Next, the power of the motor is input by the communication control unit by remote control, and the motor is rotated.
As shown in (C), the semi-circular gear 27 is rotated counterclockwise, whereby the switch 2 of the breaker 1 is moved to the lower current interruption holding release position 2A2. When the switch 2 is in the cut-off holding release position 2A2, the semicircular gear 2
7, a current interruption release position sensor 3 provided on the lower surface
2B drives the limit switch 31B, the power of the motor 22 is cut off by the contact output, and the switch 2 of the breaker 1 is held at this position. Thereafter, the rotation of the motor is reversed to rotate the semicircular gear 27 clockwise as shown in FIG. 4D, thereby moving the switch of the breaker to the upper normal position 2A3. Then, the normal time fixed position sensor 32A provided on the lower surface of the gear 27 drives the limit switch 31A, and the power of the motor 22 is cut off by the contact output. Next, the rotation of the motor is further reversed to return to the initial state shown in FIG. 5A, and the recovery operation of the breaker is completed. According to the breaker restoring device of the present invention described above, the motor, the semicircular gear, and the gear connecting them are used as main members, and the structure is simple. In addition, maintenance and inspection can be performed easily. In addition, this device has an advantage that the semicircular gear only covers the switch lever portion of the breaker when there is an abnormality, so that the breaker operation such as inspection does not always become an obstacle. Further, even when the semicircular gear stops halfway due to a failure of the breaker recovery device or the like, the switch lever of the breaker is not pinched from both sides as in the related art, so that the operator can operate the switch lever.
