復旧が終わり通常時に戻ったら、電磁操作部側回路接続手段１６ａ１と緊急操作装置側回路接続手段１７ａ、および電磁操作部側回路接続手段１６ｂ１と緊急操作装置側回路接続手段１７ｂの接続状態を解除する。次に、電磁操作部側回路接続手段１６ａ１、１６ｂ１と駆動電源部側回路接続手段１６ａ２、１６ｂ２とを接続し、通常時の状態に戻す。 When the restoration is completed and the normal state is restored, the connection state of the electromagnetic operation unit side circuit connection means 16a1 and the emergency operation device side circuit connection means 17a, and the electromagnetic operation unit side circuit connection means 16b1 and the emergency operation device side circuit connection means 17b is released. .. Next, the electromagnetic operation unit side circuit connecting means 16a1 and 16b1 and the drive power supply unit side circuit connecting means 16a2 and 16b2 are connected to return to the normal state.

なお、電磁コイル用コンデンサ１９ａは開極コイル８ａに対応しており、電磁コイル用コンデンサ１９ａからの電流は開極コイル８ａに供給される。同様に、電磁コイル用コンデンサ１９ｂは閉極コイル８ｂに対応しており、電磁コイル用コンデンサ１９ｂからの電流は閉極コイル８ｂに供給される。このため緊急操作装置側接続回路１７は、少なくとも、開極コイル８ａに対応する回路と閉極コイル８ｂにそれぞれ対応する回路を有している。 The electromagnetic coil capacitor 19a corresponds to the open pole coil 8a, and the current from the electromagnetic coil capacitor 19a is supplied to the open pole coil 8a. Similarly, the electromagnetic coil capacitor 19b corresponds to the closed pole coil 8b, and the current from the electromagnetic coil capacitor 19b is supplied to the closed pole coil 8b. Therefore, the emergency operation device side connection circuit 17 has at least a circuit corresponding to the open pole coil 8a and a circuit corresponding to the closed pole coil 8b, respectively.

また緊急操作装置１２１には、制御電源用コンデンサ２１および電磁コイル用コンデンサ１９ａ、１９ｂの蓄電状況を監視し、開閉器１の開閉制御に必要な電力が蓄積されていない、あるいは必要な電力が蓄積されていない状況に陥る可能性が高まったと判断されるときに警告を発する監視手段を設けてもよい。このような監視手段を設けることにより、電源部２０による発電をユーザが適時に実施することができ、電力不足による開閉動作制御の停止を未然に防ぐことができる。 Further, the emergency operation device 121 monitors the storage status of the control power supply capacitor 21 and the electromagnetic coil capacitors 19a and 19b, and the electric power required for the open / close control of the switch 1 is not stored or the necessary power is stored. A monitoring means may be provided to issue a warning when it is determined that the possibility of falling into an uncontrolled situation has increased. By providing such a monitoring means, the user can perform power generation by the power supply unit 20 in a timely manner, and it is possible to prevent the opening / closing operation control from being stopped due to insufficient power.

実施の形態１によれば、開閉器の開閉動作を制御する制御基板に異常が生じた場合でも迅速に開閉制御を再開させることができる。より具体的には、開閉器を開閉させる電磁操作部と電磁操作部への電力供給を制御する駆動電源部の接続において、電磁操作部側接続回路と駆動電源部側接続回路を接続することで電磁操作部と駆動電源部を接続する接続回路を構成する。電磁操作部側接続回路と駆動電源部側接続回路は、それぞれの端部に設けられた電磁操作部側回路接続手段と駆動電源部側回路接続手段により接続される。駆動電源部の制御基板に故障等の異常が生じた場合には、電磁操作部側回路接続手段と駆動電源部側回路接続手段の接続状態を解除し、開閉器の開閉動作を制御する制御基板を備えた緊急操作装置を電磁操作部側回路接続手段に接続する。これにより緊急操作装置が電磁操作部に接続され、以後は緊急操作装置により開閉器の開閉動作が制御される。この緊急操作装置は手動発電機を備えており、緊急用の電源を用意する必要は無い。このように、電磁操作部側回路接続手段の接続先を駆動電源部から緊急操作装置に切り替えるだけで開閉制御の再開が可能であるので、開閉器の開閉動作を制御する制御基板に異常が生じた場合でも、迅速に開閉制御を再開させることができる。
上記した非常時の場合以外の例として、据付後の状態確認を行う場合も同様の効果がある。すなわち、開閉器が据付された後で、まだ制御電源がつながれていない場合に、迅速に据付後の状態確認を開始することができる。According to the first embodiment, even if an abnormality occurs in the control board that controls the opening / closing operation of the switch, the opening / closing control can be restarted quickly. More specifically, in the connection between the electromagnetic operation unit that opens and closes the switch and the drive power supply unit that controls the power supply to the electromagnetic operation unit, the electromagnetic operation unit side connection circuit and the drive power supply unit side connection circuit are connected. A connection circuit that connects the electromagnetic operation unit and the drive power supply unit is configured. The electromagnetic operation unit side connection circuit and the drive power supply unit side connection circuit are connected by the electromagnetic operation unit side circuit connection means and the drive power supply unit side circuit connection means provided at their respective ends. When an abnormality such as a failure occurs in the control board of the drive power supply unit, the connection state of the circuit connection means on the electromagnetic operation unit side and the circuit connection means on the drive power supply unit side is released, and the control board controls the opening / closing operation of the switch. Connect the emergency operation device equipped with the above to the circuit connection means on the electromagnetic operation unit side. As a result, the emergency operation device is connected to the electromagnetic operation unit, and thereafter, the opening / closing operation of the switch is controlled by the emergency operation device. This emergency operation device is equipped with a manual generator, and there is no need to prepare an emergency power supply. In this way, the opening / closing control can be restarted simply by switching the connection destination of the circuit connection means on the electromagnetic operation unit side from the drive power supply unit to the emergency operation device, so that an abnormality occurs in the control board that controls the opening / closing operation of the switch. Even in such a case, the opening / closing control can be restarted quickly.
As an example other than the above-mentioned emergency case, the same effect can be obtained when checking the state after installation. That is, after the switch is installed, if the control power supply is not yet connected, it is possible to quickly start checking the state after installation.

実施の形態２．
次に、実施の形態２を図４に基づいて説明する。なお、図１から図３と同一または相当部分については同一符号を付し、その説明を省略する。図４は、実施の形態２に係る緊急操作装置の構成図である。緊急操作装置２２１は、電源部２０１と、電源部２０１からの電力を蓄積する２つの電磁コイル用コンデンサ１９ａ、１９ｂと、電磁コイル用コンデンサ１９ａ、１９ｂの放電により流れる電流を制御する制御基板１８を備えている。Embodiment 2.
Next, the second embodiment will be described with reference to FIG. The same or corresponding parts as those in FIGS. 1 to 3 are designated by the same reference numerals, and the description thereof will be omitted. FIG. 4 is a configuration diagram of the emergency operation device according to the second embodiment. The emergency operation device 221 includes a power supply unit 201, two electromagnetic coil capacitors 19a and 19b for storing electric power from the power supply unit 201, and a control board 18 for controlling the current flowing by discharging the electromagnetic coil capacitors 19a and 19b. I have.

電源部２０１は、実施の形態１の電源部２０の構成に加え、手動発電機２２と並列に接続された電池２４を備えている。さらに、手動発電機２２と制御電源用コンデンサ２１との間に電源切替スイッチ２５、すなわち電源切替手段が設けられており、電源切替スイッチ２５により制御基板１８との接続先を手動発電機２２と電池２４との間で切り替え可能となっている。電池２４としては、例えば自動車用バッテリー、乾電池、燃料電池など、制御基板１８の動作に必要な電圧以上の出力電圧を有する直流電源であればよい。
その他については実施の形態１と同様であるので、その説明を省略する。The power supply unit 201 includes a battery 24 connected in parallel with the manual generator 22 in addition to the configuration of the power supply unit 20 of the first embodiment. Further, a power supply changeover switch 25, that is, a power supply changeover means is provided between the manual generator 22 and the control power supply capacitor 21, and the power supply changeover switch 25 connects the manual generator 22 and the battery to the control board 18. It is possible to switch between 24 and 24.

In addition, a battery is connected in parallel with the manual generator in the power supply section of the emergency operation device, and a power supply changeover switch for switching the connection destination of the control circuit between the manual generator and the battery is provided. Therefore, it is possible to select whether to supply power to the control board of the emergency operation device by a manual generator or a battery, which is faster than the case where only the manual generator is used as in the first embodiment. The control circuit can be operated. This makes it possible to restart the opening / closing control of the switch more quickly.

実施の形態３．
次に、実施の形態３を図５に基づいて説明する。なお、図１から図４と同一または相当部分については同一符号を付し、その説明を省略する。図５は、実施の形態３における電磁操作装置およびこれにより操作される開閉器を示す全体構成図である。電磁操作装置３００は、駆動電源部１２に対応する電磁操作部側回路接続手段１６ａ１、１６ｂ１、すなわち第１の回路接続手段と、緊急操作装置１２１に対応する電磁操作部側回路接続手段１６ｃ１、１６ｄ１、すなわち第２の回路接続手段により電磁操作部側回路接続手段が構成されている点が実施の形態１の電磁操作装置１００と異なる。電磁操作部側回路接続手段１６ａ１、１６ｂ１、１６ｃ１、１６ｄ１は互いに並列に接続されている。電磁操作部側回路接続手段１６ａ１、１６ｂ１は実施の形態１と同様に駆動電源部側回路接続手段１６ａ２、１６ｂ２と接続され、電磁操作部側回路接続手段１６ｃ１、１６ｄ１は緊急操作装置側回路接続手段１７ａ、１７ｂと接続されている。なお、電磁操作部側回路接続手段１６ａ１、１６ｃ１は開極コイル８ａに対応し、電磁操作部側回路接続手段１６ｂ１、１６ｄ１は閉極コイル８ｂに対応している。Embodiment 3.
Next, the third embodiment will be described with reference to FIG. The same or corresponding parts as those in FIGS. 1 to 4 are designated by the same reference numerals, and the description thereof will be omitted. FIG. 5 is an overall configuration diagram showing the electromagnetic operating device according to the third embodiment and the switch operated by the electromagnetic operating device. The electromagnetic operating device 300 includes electromagnetic operating unit side circuit connecting means 16a1 and 16b1 corresponding to the drive power supply unit 12, that is, the first circuit connecting means and electromagnetic operating unit side circuit connecting means 16c1 and 16d1 corresponding to the emergency operating device 121. That is, it differs from the electromagnetic operating device 100 of the first embodiment in that the electromagnetic operating unit side circuit connecting means is configured by the second circuit connecting means. The electromagnetic operation unit side circuit connecting means 16a1, 16b1, 16c1, 16d1 are connected in parallel with each other. The electromagnetic operation unit side circuit connection means 16a1 and 16b1 are connected to the drive power supply unit side circuit connection means 16a2 and 16b2 as in the first embodiment, and the electromagnetic operation unit side circuit connection means 16c1 and 16d1 are emergency operation device side circuit connection means. It is connected to 17a and 17b. The electromagnetic operation unit side circuit connecting means 16a1 and 16c1 correspond to the open pole coil 8a, and the electromagnetic operation unit side circuit connection means 16b1 and 16d1 correspond to the closed pole coil 8b.

電磁操作部側回路接続手段１６ａ１、１６ｂ１、１６ｃ１、１６ｄ１と電磁操作部４の間には、回路切替スイッチ２６、すなわち回路切替手段が設けられている。回路切替スイッチ２６は、例えば手動切替スイッチであり、電磁操作部４の接続先を駆動電源部１２と緊急操作装置１２１との間で切り替える。このため、電磁操作部側回路接続手段１６ａ１と駆動電源部側回路接続手段１６ａ２、電磁操作部側回路接続手段１６ｂ１と駆動電源部側回路接続手段１６ｂ２、電磁操作部側回路接続手段１６ｃ１と緊急操作装置側回路接続手段１７ａ、電磁操作部側回路接続手段１６ｄ１と緊急操作装置側回路接続手段１７ｂの機械的な接続状態は通常時および緊急時の両方で維持されることとなる。
その他については実施の形態１と同様であるので、その説明を省略する。A circuit changeover switch 26, that is, a circuit changeover means is provided between the electromagnetic operation unit side circuit connecting means 16a1, 16b1, 16c1, 16d1 and the electromagnetic operation unit 4. The circuit changeover switch 26 is, for example, a manual changeover switch, and switches the connection destination of the electromagnetic operation unit 4 between the drive power supply unit 12 and the emergency operation device 121. Therefore, the electromagnetic operation unit side circuit connection means 16a1, the drive power supply side circuit connection means 16a2, the electromagnetic operation unit side circuit connection means 16b1, the drive power supply side circuit connection means 16b2, the electromagnetic operation unit side circuit connection means 16c1 and emergency operation.

Others are the same as those in the first embodiment, and the description thereof will be omitted.

Further, the electromagnetic operation unit side circuit connecting means has a first circuit connecting means corresponding to the drive power supply unit and a second circuit connecting means corresponding to the emergency operation device, and the electromagnetic operation unit side circuit connecting means and the electromagnetic operation. A circuit changeover switch provided between the units makes it possible to switch the connection destination of the electromagnetic operation unit between the drive power supply unit and the emergency operation device. Therefore, in an emergency, the connection destination of the electromagnetic operation unit may be switched from the drive power supply unit to the emergency operation device by the circuit changeover switch, in order to connect the circuit connection means on the electromagnetic operation unit side and the circuit connection means on the emergency operation device side. It is not necessary to disconnect the drive power supply side circuit connecting means from the electromagnetic operation unit side circuit connecting means. Therefore, the emergency operation device can be easily connected, and the opening / closing control of the switch can be restarted more quickly.
