The coil of the electromagnetic excitation breaking means is rapidly demagnetized by a capacitor discharge or the like, and the vacuum and the tube are disconnected by the electromagnetic repulsive force of the coil current and the eddy current of the copper plate. In circuit breakers with electromagnetic repelling mechanisms, there are DC circuit breakers and high-speed circuit breakers. The former is to inject the charge previously charged to the capacitor in the opposite direction of the system current, and forcibly creates a current zero point to be disconnected. When a ground fault occurs in the DC system, a fast rising ground current is determined by the circuit constant ® of the resistor and the inductor. Therefore, high speed responsiveness is required in the disconnection operation. • On the one hand, the latter is about the self-contained power generation system, and is introduced to prevent the power outflow from the power generator side when the power system is out of power, to avoid high-speed switching from the power outage system. It is aimed at the continuation of the operation of important loads due to a sound system. Both accept the responsiveness within a few m s after the disconnection command, and thus the electromagnetic repulsion mechanism is utilized. As a circuit breaker that carries the electromagnetic repulsion mechanism, as shown in Patent Document No. 5-200807472 (2), there is provided a vacuum tube, an operating mechanism provided in an opening and closing direction of the vacuum tube, and an operating mechanism provided in the operating mechanism. The electromagnetic repulsion mechanism on the way is also a mechanism for reducing the automatic reduction of the shaft on the movable electrode side during the interruption of the current interruption. In the conventional circuit breaker described above, not only a predetermined breaking speed but also a need to maintain the disconnection state is required at the time of high-speed disconnection. The attraction force of the permanent magnet is also high, and the electromagnetic repulsive force is high. Therefore, it is necessary to increase the size of the electromagnetic repulsion mechanism and increase the power supply capacity. Further, between the vacuum tube and the operating mechanism, the electromagnetic repulsion mechanism and the mechanism for reducing the automatic reduction of the shaft on the movable electrode side generated when the electromagnetic repulsion mechanism is actuated are arranged in series in the vertical direction, and thus the vacuum tube is used. The operating mechanism is used to open and close the vacuum tube. It is necessary to move the electromagnetic repulsion mechanism and the automatic reduction mechanism of the shaft on the movable side of the movable electrode. Therefore, the operation mechanism of the vacuum tube, for example, in the case of the electromagnetic operation mode, must be increased, and the capacity of the permanent magnet, the exciting coil, and the like of the component is increased, so that the operating mechanism of the vacuum tube is enlarged. Further, along with this, there is a possibility that the operability of the operating mechanism of the vacuum tube is lowered. The present invention provides a circuit breaker which is capable of reducing the conduction state due to the electromagnetic repulsion mechanism and which is easy to manufacture, and which can reduce the automatic reduction of the movable electrode side shaft when the current is interrupted, and has good operability. purpose. -6- 200807472 (3) In order to achieve the above object, the first invention is a circuit breaker comprising: a vacuum tube, and an operating mechanism for maintaining the vacuum tube in a conducting state by the attraction force of the permanent magnet, and by electromagnetic repelling A circuit breaker for acting as a disconnecting means for driving an operating shaft of the operating mechanism in an opening direction, characterized in that: between the opening means and the operating means, a disconnection due to the disconnecting means is provided The opening operation is to cancel the mechanism of the conduction state of the vacuum tube caused by the above operation mechanism.

Further, the third invention is a circuit breaker comprising: a vacuum tube; and a circuit breaker that opens the operation shaft of the vacuum tube in an opening direction by electromagnetic repulsion, and has a coil, An electromagnet composed of a movable core and a permanent magnet includes: energizing the coil to perform an operation of closing the vacuum tube, and maintaining the conduction state of the vacuum tube by the attraction force of the permanent magnet, and exciting in a direction opposite to the ON operation The above-mentioned coil is used to open the vacuum tube, and the actuator 7-(4)(4)200807472 is connected to the opening state of the vacuum tube by the opening operation due to the disconnection means. A release mechanism formed by the lever mechanism of the above operating mechanism. Further, according to a fourth aspect of the invention, a circuit breaker includes a circuit breaker including two switches of a main switch and a sub-switch that operates in conjunction therewith, and is characterized in that: one of the switch groups is provided a breaking means for driving the operating shaft in the breaking direction by the electromagnetic repulsive action, and an electromagnet comprising a coil, a movable iron core, and a permanent magnet, and exciting the coil for the two switch groups to perform the closing operation The conduction state is maintained by the attraction force of the permanent magnet, the excitation is performed in the opposite direction to the ON operation, the operation mechanism for performing the OFF operation by the coil, and the opening operation by the disconnection means are performed.

According to a fifth aspect of the invention, there is provided a circuit breaker comprising: a circuit breaker having two switch groups including a main switch and a sub-switch that operates in conjunction therewith, wherein the switch breaker includes one of the switch groups a breaking means for driving the operating shaft in the breaking direction by the electromagnetic repulsive action, and an electromagnet comprising a coil, a movable iron core, and a permanent magnet, and exciting the coil for the two switch groups to perform the closing operation The conduction state is maintained by the attraction force of the permanent magnet, and the operation mechanism that excites the coil in the opposite direction to the ON operation and performs the OFF operation, and the opening operation due to the disconnection means are released. The main switch is connected to the release mechanism of the lever mechanism of the operating mechanism in the conductive state. Further, in the invention of the sixth item, in the inventions of the above-mentioned items, the above-mentioned items are referred to as the above-mentioned breaking means and the above-mentioned operating means. According to a seventh aspect of the invention, in the fourth aspect of the invention, the timing of the operation of the two switch groups that are turned off by the electromagnetic repulsion by the conduction means is provided in the release mechanism The adjustment hand-segment to be adjusted is its characteristic. According to the present invention, the automatic reduction of the movable electrode side shaft generated during the current interruption due to the electromagnetic repulsion mechanism can be reduced with a simple configuration, thereby suppressing an increase in the size of the operation mechanism of the vacuum tube, and The slight force can quickly release the current interruption caused by the electromagnetic repulsion mechanism.

Fig. 7 is a timing chart showing an operation at the normal operation of an embodiment of the rectifying DC circuit breaker of the circuit breaker of the present invention shown in Fig. 1. First, a method of using and a method of operating an embodiment of a rectifying DC circuit breaker of a circuit breaker according to the present invention will be described with reference to Figs. 5 to 7. In Fig. 5, reference numeral 1 is a DC power supply, and a voltage of a positive electrode of 15 〇〇 V is supplied to a general DC feed circuit. 2 is a load indicating a train or the like. 3 is a feeder wire '4 for supplying electric power to the load', and is a return line indicating the connection load 2 and the DC power source 1. The rectifying DC circuit breaker 5 of the circuit breaker of the present invention is inserted in the middle of the feeder line 3, and the switch supplies power from the DC power source 1 to the load 2. The rectifying DC circuit breaker 5 is composed of a first main switch 5 1 'the second main switch 52, a first sub-switch 5 3, and four switches of the second sub-switch 5 4, and a control device 5 。. A first capacitor 55' is connected to the rectifier capacitor 5, and a second capacitor 56 is connected to the reactor. The first main switch 51 and the second main switch 52 are inserted in series in the feeder 3' and will be first. The main switch 51 is disposed on the DC power source 1 side, and the second main switch 52 is disposed on the load 2 side. The first sub-switch 5 3 is connected in series with the first capacitor 5 5 and the reactor 5 -10 - 07074072 (7) The circuit is connected in parallel to the first main switch 5 1 and the second sub-switch 54 is connected in series with the capacitor 5 6 The circuit is connected in parallel to the first capacitor 5 5 « The converter 58 provided in the feeder 3 is for detecting the flow of the feeder 3 and inputting its current 値 to the overcurrent trip device 59. Overcurrent * The device 59 has an automatic disconnection setting 値, and an output disconnection command 1 1 is made when the current of the feeder 3 reaches the set value of * or more. The control 50 receives the external command 10 or the overcurrent trip device 5 9 * the open command 11 and gives the open/close command to the rectifier DC breaker 5. The first sub-switch 5 is interlocked with the first main switch 5, and after the first switch 51 is turned off, the delay time 11 (for example, 2 ms) is turned on, and then turned off. On the one hand, the second sub-switch 5 4 is connected to the main switch 52, and the second main switch 52 is disconnected before the time 12 (2.5 ms) of the disconnection. When the load 2 is operated, the first main switch 5 1 and the second main 52 are turned on, and a DC of 1 500 V is applied to the load 2. At this time, the first sub-opening | ^ is turned off, and the second sub-switch 54 is turned on. Further, the first capacitor and the second capacitor 56 are charged with the DC power source 1 side as a reference + 2 0 0 0 V. _ When a failure of the load 2 occurs or a grounding accident of the feeder 3 occurs, a current that rises rapidly due to the circuit constant is applied to the feeder line 3. For example, the circuit resistance is 1 5 m Ω 'circuit inductance 1 5 0 // Η when the arrival current is A, and the maximum rush rate is 10 k A/ms. In the case of such an accident current, in order to suppress the influence on the equipment, the accident current is disconnected at a high speed. First, in the converter 58, it is detected that the device is electrically disconnected from the first electric circuit breaker, and the second, for example, the switch S53 is completed, and the current occurs at a maximum of -11 - 200807472 (8) 値, and Input to the overcurrent trip device 5 9 . If the automatic disconnection setting of the overcurrent trip device 59 is set to, for example, 1 2000A, the disconnection command 1 1 is sent to the control device 50 when the accident current 値 reaches 1 2000A. The first main switch 5 1 is caused to be disconnected by an instruction from the control unit 50. With the opening of the first main switch 51, the first sub-switch 53 is delayed - time 11 to be turned on. Thereby, the first capacitor 5 5, the second capacitor 56, the reactor 57, the first main switch 51, the first sub-switch 53, and the Φ second sub-switch 54 constitute an LC resonance circuit, so that the pre-charged A capacitor 5 5 and the second capacitor 56 are discharged, and a rectified current in a direction opposite to the direction of the accident current is injected into the first main switch 51. When the electrostatic capacity of the first capacitor 55 is 60 // F and the electrostatic capacity of the second capacitor 56 is 1 200 // F, the rectified current 相反 in the opposite direction is 40 kA at the maximum, so if it is in an accident When the current 値 reaches 40kA, the first sub-switch 5 3 is turned on, and the accident current and the rectified current are killed. When the current of the first main switch 51 becomes zero, the first main switch 51 completes the Φ open circuit. After the first main switch 5 1 is turned off, the second main switch 52 is turned off after the delay time t3, but if the time t3 is set to satisfy the condition of 13 > t1 + t2, then the first sub switch The second sub-switch 54 is not turned off before the conduction is applied, so that the first capacitor 5 5 and the second capacitor 5 6 can be simultaneously discharged, as described above, which can correspond to a large current. Further, even if the first main switch 51 completes the disconnection, the first sub-switch 53 and the second sub-switch 54 both have an ON state, and thus the first capacitor 5 5 and the second capacitor 56 are supplied with a DC power source. 1 is charged. This charging current is caused by the charging voltage rising, and when the circuit current is zero, it becomes -12-200807472 Ο) The timing of the vacuum tube's off current 値 is broken. On the other hand, the disconnection operation ' of the rectifying DC circuit breaker 5 in the normal operation state is by using the external command 10 . When the external command 1 is used to accept the disconnection command, the first main switch 5 1 and the second main switch 52 are simultaneously turned off. At this time, the table-one switch 54 is turned off before the second main switch 52 is turned off. Therefore, when the first sub-switch 5 is turned on, it becomes a _LL brother. The LC resonant circuit is formed by a 55' reactor 55' first main switch 51 and a #1 sub switch 53. Of the first capacitor 55 and the second capacitor 56 that have been previously charged, only the first capacitor 55 is discharged, and the rectified current in the opposite direction to the direction of the load current is injected into the first main switch 51. Here, the maximum value of the load current is equal to or lower than the setting 过1 2 0 0 0 A of the overcurrent trip device 59. If only the first capacitor 55 is discharged, the maximum rectified current is 1/4 or less. Then, the maximum negative current is 12000A', and at the timing when the %-main switch 51 becomes zero, the first main switch 51 completes the open circuit. Further, the second main opening/closing 52 functions to cut off the load 2, the first capacitor 55, and the second capacitor 56 after the breaker is turned off, thereby preventing the electric_container charging voltage of the load side circuit. Electrical shock. " Hereinafter, an embodiment of the rectifier type DC circuit breaker of the above-described circuit breaker of the present invention will be described using Figs. 1 to 4 . An embodiment of the rectifying DC circuit breaker 5 of the circuit breaker according to the present invention is constructed by two electromagnets and a mechanical link, and automatically realizes the operation timings of the four switches. In the first to fourth figures, the operation state (the first main switch 5 and the second main switch 52 are in an on state) are shown.

The opening action of the switch 52. In the case of a high-speed disconnection at the time of an accident, the electromagnetic electromagnetic repels the coil 170. By the electromagnetic repulsive force occurring on the repulsive plate 177, the operating rod 65 is moved by a more curved compression spring 1 51. The first main switch 5 is turned off, and the first main switch 5 is turned off. A pair of switches 53 is in an on state. At this timing, the spindle 500 and the counter shaft 510 are inoperative, and the states of the second main switch 52 and the second main switch 54 are still maintained. By the electromagnetic repulsive force of the repulsive plate 177 for the electromagnetic repulsive coil 1 7 ' 'when the operating lever 65 moves upward again, the lever 5 8 5 and the electromagnet provided on the release mechanism 90 卡 are engaged The pin 3 8 3 of the shaft 3 0 2 of 3 0 1 causes the electromagnetic repulsive force to be transmitted to the pin 5 8 3 . When the transmission force and the load of the pressure springs 151, 2 1 2 and the load of the dancer springs 5 5 5 exceed the attractive force of the permanent magnets (16) (16) 200807472 3 06, the plungers 34 start upward. mobile. In response to this action, the second main switch 52 and the second sub-switch are turned off, and the re-on is prevented. In the above-described high-speed disconnection of the disconnecting means, it is necessary to reduce the force of the reaction force of the pressing springs 151, 212 and the dancer springs 5 5 5 from the attraction force of the permanent magnets 306, that is, to exceed the amount of the driving force for maintaining the conduction state. The electromagnetic repulsive force of the residual force acts on the movable portion of the electromagnet 301. As is conventionally known, if the electromagnetic repulsive force is directly applied to the electromagnetic movable portion, there is a risk that the contact will be reconnected by its reaction force. In the present embodiment, the release mechanism 9 of the electromagnet 301 including the insulating rod 581, the lever 585, and the pin 583 is provided. Therefore, the release mechanism 900 is a lever lever. The force required to release, as shown in Fig. 1, can be reduced to L1/L2, that is, the electromagnet 301 can be released by the slight manipulation force caused by the release mechanism 900. As a result, the reaction ratio when the electromagnet 3 0 1 is released is reduced. The danger of re-switching the main switch can be avoided. Further, the release mechanism 900 is also a function of the timing of the operation of the second main switch 5 2 and the second sub-switch 5 4 when the high-link disconnection is adjusted. The timing of the operation between the main switch and the sub-switch to which the operation is carried out is adjustable in the connection members 5 3 0, 540 shown in Figs. 1 and 2, but the individual operation between the two switch groups is performed. The device transmits commands that are staggered at various timings, and the like, and requires a complicated mechanism and configuration. In the present embodiment, only the timing at which the shaft lever 5 82 is engaged with the pin 583 can be adjusted, and it can be easily realized. According to the embodiment of the present invention described above, the simple configuration can be reduced -20-

When the current is interrupted, the movable electrode side is generated. The permanent magnet of the operating mechanism of the vacuum tube and the movable iron core, that is, the vacuum tube, can provide a highly reliable circuit breaker. 8 to 11 are views showing an embodiment of a circuit breaker 600 of a circuit breaker according to the present invention, and Fig. 8 is a right side sectional view showing a three-phase high speed circuit breaker 600 of the present invention, and Fig. 9, Fig. 1 The map is a front view and is always on. Fig. 1 is a view showing a state immediately before the electromagnet 3 0 1 is released. Here, the same reference numerals in the first to fourth figures are the same parts. In these figures, the 'three-phase high-speed circuit breaker 600 is a vacuum tube 6 0 having contact points that are in contact with each other. The fixed conductor 602 on the side of the vacuum tube 610 is located on the upper side and is connected to the g line 603. On the other hand, the movable conductor 604 on the movable electrode side, the electric portion 605 is disposed on the lower side, and is electrically connected to the movable side, and the movable conductor 604 is fixed to the other end of the rod 605 connected to the insulating rod 607. On the operating lever 6 〇 8. The operating lever is passed through a pin 609 which is applied to the abutting surface of the plane processing at the upper and lower portions. The levers of one of the three phases that are engaged with one of the single spindles 500 are supported by a nut 610 fixed to the pin 605 and the lever 6 0 8 , and the clamp spring 612 and the washer 6 〖3. In the vacuum tube 601 is automatically adsorbed by the large-fee repeller of the movable electrode mechanism, and the 3-phase high-speed open circuit is a rear view in the side sectional view, and the fixed-side feeding of the fixed electrode in the interior is via the poly Line 606. end. The insulation 608 is a portion in which the cross pin 609 is ί 503 °, the F washer 6 1 1 is opened - 21 · 200807472 (18), and the lower portion of the operating lever 6 0 8 is engaged by the pressing spring 6 1 2 The status of 620 and pin 609. On the one hand, in the guidance of the vacuum tube 6〇1, when the fixed contact 621 and the movable 622 of the vacuum tube 601 are contacted, the engagement of the pin 609 with the hexagonal portion 620 is released, and the load of the spring 6 1 2 is Become the contact force of the joint. ^ The operating lever 60 8 is connected to the electromagnetic repulsive coil and the repeller plate 171 which constitute the breaking means. The electromagnetic repulsive force of the repulsion plate 171 is generated by the electromagnetic repulsive coil 170. The electromagnetic repulsive force of the repulsion plate 171 is the same as that of the above-described embodiment, and the structure is received by the insulating rod 607, and the same repulsive force is used. It is moving in the lower direction of the figure. The operating lever 607 is driven in the operator box 300 by the electromagnet 301 for the vacuum tube 601, and the shaft 302 of the electromagnet 301 is the other lever 501 connected to the main shaft 510 via 3 〇3. Further, the attraction force of the electric power 301 is transmitted to the operating lever 607 via the main shaft 500. When the vacuum tube 6 0 1 is passed, the coil 3 0 5 in the exciting electromagnet 3 0 1 is driven, and the plunger 3 04 is driven in the middle and lower directions of φ. Below the spindle 500, the lever 5 0 3, 5 0 1 is provided with a release mechanism 900 for the electromagnet. The release mechanism 900 of the electromagnet 301 is a perturbation lever 63 2 that is rotatable about a shaft 63, and is often provided to the interference lever 6 3 2 and 5 旋转 as the interference lever 6 3 2 is rotated toward the 3 〇 3 side. A lever mechanism of a coil spring 63 3 (refer to Fig. 7) between 1 is formed. The shaft 6 3 1 of the release mechanism 900 is disposed on the side of the electromagnet 30 1 in order to effectively exert the lever. One end of the interference lever 63 2 abuts against the member 303, and the other end of the interference lever 63 2 is located at the hexadecimal point of contact 170. The phase becomes a rod arrangement member magnet to be connected to FIG. 30 1 : The principle of the component lever is the end of the hexagon 620 of the lower portion of the rod 608 operating -22-200807472 (19). Hereinafter, the operation of an embodiment of the three-phase high-speed breaker 600 of the above-described circuit breaker of the present invention will be described. In the ON operation, the coil 305 of the electromagnet 301 is excited by the pre-charged capacitor 5 90 shown in Fig. 8, and the attraction force occurs in the plunger 3〇4. The same attraction force is transmitted to the operating lever 607' via the spindle 500, and the movable conductor 604 is driven upward to turn on the vacuum tube 601. At the same time as the Φ-pass operation, the pressure-receiving spring 6 1 2 and the trip spring 5 5 5 are stored and have an opening operation. When the closing operation is completed, the energization of the electromagnet 301 is released. The reaction force of the pressure-receiving pressure-receiving spring 612 and the trip spring 55 5 is maintained by the attraction force of the permanent magnets 306 inside the electromagnet 301. In the normal opening operation of the vacuum tube 601, the coil 3 0 5 is excited in the reverse direction during the closing operation. The magnetic flux of the permanent magnet 306 is eliminated by the reverse excitation of the coil 350, and the opening of the vacuum tube 601 is started when the attraction of the electromagnet 301 drops to the reaction force of the spring. ® High-speed disconnection of the vacuum tube 60 1 at the time of the accident, and electromagnetic repulsion coil 170 of the excitation breaking means. By the electromagnetic repulsive force „ occurring on the repulsive plate 171, one side of the operating lever 607 is more curved and the pressing spring 612 is moved in the downward direction, so that the vacuum tube 601 is turned off. At this time, the spindle 500 is not Moving, as shown in Fig. 9, by moving the operating lever 607 downward by electromagnetic repulsion, the operating lever 607 collides with the interference lever 63 2, and this collision force is transmitted to the member 303. When the communication force is transmitted When the total load of the pressure spring 612 and the dancer spring 515 exceeds the suction force of the permanent magnet 306, the plunger 304 -23 - (20) 200807472 moves upward. In response to this action, the high speed circuit breaker mechanism moves. The breaking force of the vacuum tube 601 in the above-described disconnecting means reduces the force of the reaction force of the pressing spring 612 5 5 5 from the attraction force of the permanent magnet 306, and is soon more than the conduction state for maintaining. The electromagnetic repulsive force of the residual force acts on the electromagnetic moving part. As in the prior art, if the electromagnetic repulsive force is directly actuated, the reaction force is reconnected by the reaction force, and the shaft 631 is disturbed. Lever 63 2 The configured release mechanism 900 is solved. As shown in Fig. 9, the 900 is a lever principle, and the force of the movable portion of the electromagnet can be reduced to L 1 / L2 times. The micro-operating force can release the electromagnet 3 0 1. As a result, the reaction ratio at 301 is reduced. The danger of the vacuum tube 601 can be avoided. Moreover, in the present embodiment, the accident current for high-speed disconnection is used to switch the load. The impact force of the electromagnetic repulsive force of the electromagnet to form an individual path is large, and the degree of each member must be enhanced in order to correspond to the closing. The reinforcing strength is an increase in the quality of the closing, and the electric power failure cycle is required to be enhanced in order to open and close at a high speed. It is sufficient to limit the high-speed disconnection to the durability of the accident current interruption to several tens of times, and it is possible to solve the electromagnet described in the above-described textbook embodiment, and the vacuum tube 6 0 1 can be disconnected when the operation is reversed. Therefore, the operation path of 600° must be used and the spring spring tube 601 iron 3 0 1 can be used for electromagnetic. In this embodiment, the electromagnet 3 (Η this release mechanism is released) The electromagnet that re-connects the electromagnet released by the mechanism 900 is required, and the state speed is broken when the multi-frequency is connected to the magnetic repulsive force of the movable portion to ensure a number of questions. In addition, the direction is excited to make the change negative - 24-200807472 (21) The electromagnet used for the current interruption and the accident current interruption is changed only by the control method, and the constituent members are not changed. According to this embodiment, as in the above-described embodiment, the configuration can be reduced with a simple configuration. The automatic reduction of the movable electrode side shaft caused by the current interruption caused by the electromagnetic repulsion mechanism can suppress the enlargement of the operation mechanism of the vacuum tube, and can be quickly released with a slight force. The movable electric φ generated by the electromagnetic repulsion mechanism is automatically restored during the current interruption, and the adsorption of the permanent magnet of the vacuum tube operating mechanism and the movable iron core, that is, the conduction of the vacuum tube, provides a highly reliable disconnection. Fig. 1 is a left side view showing another embodiment of the rectifying DC circuit breaker of the circuit breaker according to the present invention, and Fig. 1 and Fig. 1 The same symbols are the same part, and thus a detailed description thereof will be omitted. In this embodiment, the lever 5 1 3 located at the middle portion of the right side of Fig. 2 is disposed, and the other lever 1 0 0 0 is disposed. The lever 10 〇 〇 is provided on one side of the member 1001 on the side of the member 1001 of the operating lever 65, and the other side is located on the side of the insulating rod 52, and is rotatably provided to the lever 513 via the shaft 1〇〇2. Therefore, when the high-speed disconnection caused by the upward movement of the repulsive plate 117 of the disconnecting means is moved upward by the operating lever 65, the member 1 001 abuts on one side of the lever 1 000 at the position P, The lever 1 000 is rotated in the counterclockwise direction with the shaft 1 〇〇 2 as a fulcrum. By the rotation of the lever 1 000 in the counterclockwise direction, the other side of the lever 1 1 collides with the insulating rod 502 at the position Q. Thereby, the insulating rod 503 moves downward, and the lever 501 on the electromagnet side is rotated in the clock direction, and the electromagnet 301 is made to be released. As a result, the reaction force of the discharge magnet 3 〇 1 is reduced, and the risk of the main switch being reconnected can be avoided. According to this embodiment, as in the above-described embodiment, the automatic reduction of the movable electrode side shaft generated during the current interruption due to the electromagnetic repulsion mechanism can be reduced by a simple configuration, so that the operation of the vacuum tube can be suppressed. The size of the mechanism is increased, and the automatic reduction of the movable electrode side shaft generated during the current interruption caused by the electromagnetic repulsion mechanism can be quickly removed with a slight force, and the permanent magnet and the movable iron core of the operating mechanism of the vacuum tube are Adsorption, that is, conduction of a vacuum tube, can provide a highly reliable circuit breaker.
