Description

断路器の操作装置Disconnector operating device
　この発明は、例えば絶縁性ガスが封入された密封容器内に開閉機器を収納しているガス絶縁スイッチギヤなどに使用され、断路器の手動および電動での開閉操作を行う断路器の操作装置に関するものである。 The present invention relates to an operating device for a disconnector used for, for example, a gas-insulated switchgear in which an opening / closing device is housed in a sealed container in which an insulating gas is sealed, and for manually and electrically operating the disconnector. Is.
　一般に、ガス絶縁スイッチギヤはＳＦ６ガスの優れた絶縁性能により機器をコンパクト化し、スイッチギヤ全体の省スペース化が進んでいる。例えばガス絶縁スイッチギヤに搭載される断路器と接地開閉器の機能を併せ持つ三位置断路器の場合には、三位置断路器の主回路部はＳＦ６ガスが封入された圧力容器の内側に配置され、圧力容器の外側に配置された操作装置の駆動源としてのモータの駆動力が出力軸を介して三位置断路器の主回路部の可動接触子に与えられて、三位置断路器は入状態と切状態および接地状態に動作する。
従来、このような三位置断路器において、三位置断路器の状態検出と操作装置のモータ停止位置検出の機能を兼ね備えた４個のリミットスイッチまたは２個のＣ接点付リミットスイッチを使用した開閉器の操作装置が提案されている。（例えば、特許文献１）
　また、光電スイッチもしくはリミットスイッチ等の機械式スイッチを使用して接地状態や開放状態を検出するとともに、このスイッチの接点をモータの電源のシーケンス回路に組込むことで、接地電極の開閉を行うモータの回転を自動的に停止させる接地装置が提案されている。（例えば、特許文献２） In general, gas-insulated switchgear is made compact by the excellent insulation performance of SF 6 gas, and space saving of the entire switchgear is progressing. For example, in the case of a three-position disconnector having both functions of a disconnector mounted on a gas-insulated switchgear and a grounding switch, the main circuit portion of the three-position disconnector is arranged inside a pressure vessel filled with SF 6 gas. The driving force of the motor as the driving source of the operating device arranged outside the pressure vessel is applied to the movable contact of the main circuit portion of the three-position disconnector via the output shaft, and the three-position disconnector is turned on. Operates in state, off state and ground state.
Conventionally, in such a three-position disconnector, a switch using four limit switches or two limit switches with C contacts that have both functions of detecting the state of the three-position disconnector and detecting the motor stop position of the operating device. An operating device has been proposed. (For example, Patent Document 1)
In addition, a mechanical switch such as a photoelectric switch or a limit switch is used to detect a grounding state or an open state, and the contact of this switch is incorporated into the motor power supply sequence circuit to open and close the ground electrode. A grounding device that automatically stops rotation has been proposed. (For example, Patent Document 2)

　従来の開閉器の操作装置においては三位置断路器の状態検出と操作装置のモータ停止位置検出の機能を兼ね備えたリミットスイッチを使用している。また、従来の接地装置においても接地状態や開放状態を検出するスイッチを使用して接地電極の開閉を行うモータの停止を行うものである。このため、例えば三位置断路器などの状態を他の複数の機器に対して通知する必要のある場合など、複数の状態検出用リミットスイッチが必要となるが、複数の状態検出用リミットスイッチを設けた場合に、状態検出用リミットスイッチの一つまたは数個にモータ停止の機能を兼用させると、状態検出用リミットスイッチの個体差や組立ばらつきなどにより、モータが停止しても状態検出が完了していない状態検出用リミットスイッチが発生する場合があるなどの誤動作を生じる場合が想定されるため、モータ停止位置検出と兼用することなく、別の位置に独立した状態検出用のリミットスイッチが複数個必要となるという課題があった。 The conventional switch operating device uses a limit switch that combines the functions of detecting the state of the 3-position disconnector and detecting the motor stop position of the operating device. Also in the conventional grounding device, the motor for opening and closing the ground electrode is stopped by using a switch for detecting the ground state and the open state. For this reason, for example, when it is necessary to notify other devices of the status of a three-position disconnector, etc., multiple status detection limit switches are required, but multiple status detection limit switches are provided. If one or several of the limit switches for status detection also have a motor stop function, the status detection will be completed even if the motor stops due to individual differences in the limit switches for status detection or assembly variations. It is assumed that a malfunction may occur, such as a status detection limit switch that does not exist, so there are multiple independent status detection limit switches at different positions without using the motor stop position detection. There was a problem that it was necessary.
　この発明は以上のような課題を解決するためになされたもので、複数の独立した状態検出用のリミットスイッチを有する断路器の操作装置を提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an operating device for a disconnector having a plurality of independent state detection limit switches.
　この発明に係る断路器の操作装置は、断路器本体の可動接触子に出力軸を介して駆動力を与えるモータと、前記モータの駆動力で回動する軸の周りに設置され前記断路器本体の入状態および切状態でのモータ停止位置をそれぞれ検出するモータ停止用リミットスイッチと、前記モータの駆動力で回動する軸の周りに設置されて前記断路器本体の入状態および切状態を検出する複数の状態検出用リミットスイッチを備えていることを特徴とするものである。 An operating device for a disconnector according to the present invention includes a motor that applies a driving force to a movable contactor of the disconnector body via an output shaft, and the disconnector body that is installed around an axis that is rotated by the driving force of the motor. A motor stop limit switch that detects the motor stop position in each of the on and off states of the motor, and an on / off state of the disconnector body that is installed around a shaft that is rotated by the driving force of the motor. And a plurality of state detection limit switches.

　図１において、断路器本体である三位置断路器１は、ＳＦ６ガスが封入された圧力容器の内側に配置された主回路部の可動接触子（図示せず）を、断路器の操作装置１００の出力軸１３に直結されて圧力容器の気密性を保持したまま貫通している操作軸（図示せず）で操作することにより、入状態と切状態および接地状態に動作する。断路器の操作装置１００は、三位置断路器１側から状態検出用リミットスイッチ部２、メイン機構部３、モータ停止用リミットスイッチ部４およびシャッタ部５で構成されている。シャッタ部５は、主に手動操作ハンドルの挿入を制御するシャッタで構成されており、断路器の操作装置１００の手動操作をシャッタ部５側から行うものであるが、従来のものと同様構成であり詳細な説明は省略する。 In FIG. 1, a three-position disconnector 1 as a disconnector body is configured such that a movable contact (not shown) of a main circuit portion disposed inside a pressure vessel filled with SF 6 gas is used as an operating device for the disconnector. By operating with an operation shaft (not shown) that is directly connected to the output shaft 13 of the 100 and is penetrating while maintaining the airtightness of the pressure vessel, it operates in the on state, the off state, and the ground state. The disconnecting device operating device 100 includes a state detecting limit switch section 2, a main mechanism section 3, a motor stopping limit switch section 4 and a shutter section 5 from the three-position disconnecting switch 1 side. The shutter unit 5 is mainly composed of a shutter for controlling insertion of a manual operation handle, and performs manual operation of the disconnecting device operating device 100 from the shutter unit 5 side. Detailed explanation is omitted.
　図２および図３において、モータ停止用リミットスイッチ部４は、歯車１０ａおよび歯車１０ｂによって連動して回動するＤＳ操作軸１４とＥＳ操作軸１５が設けられており、歯車１０ａに駆動用のモータ１６の回転軸に取付けられた歯車が噛み合っており、ＤＳ操作軸１４とＥＳ操作軸１５はモータ１６の駆動力により回動する。ＤＳ操作軸１４には、入状態時モータ停止用カム１８ａが固着されており、その軸の周りに取付けられた入状態時モータ停止用リミットスイッチ１９ａを動作させる。また、ＥＳ操作軸１５には、切状態時モータ停止用カム１８ｂと接地状態時モータ停止用カム１８ｃが固着されており、その軸の周りに取付けられた切状態時モータ停止用リミットスイッチ１９ｂと接地状態時モータ停止用リミットスイッチ１９ｃをそれぞれ動作させる。 2 and 3, the motor stop limit switch unit 4 is provided with a DS operation shaft 14 and an ES operation shaft 15 that rotate in conjunction with a gear 10a and a gear 10b, and the gear 10a has a drive motor. The gears attached to the 16 rotation shafts mesh with each other, and the DS operation shaft 14 and the ES operation shaft 15 are rotated by the driving force of the motor 16. The DS operation shaft 14 is fixed with a motor stop cam 18a in the on state, and operates a limit switch 19a for stopping the motor in the on state attached around the shaft. Further, the ES operation shaft 15 is fixed with a motor stop cam 18b in the off state and a motor stop cam 18c in the ground state, and is connected to the shaft around the shaft and has a motor stop limit switch 19b. The motor stop limit switch 19c is operated in the grounding state.
　なお、入状態時モータ停止用リミットスイッチ１９ａは、三位置断路器１が切状態から入状態に移行した後に駆動用のモータ１６を停止するものである。切状態時モータ停止用リミットスイッチ１９ｂは、三位置断路器１が入状態から切状態に移行した後および接地状態から切状態に移行した後の両方を共用して駆動用のモータ１６を停止するものであり、共用化することによりリミットスイッチの使用数を少なくできる。接地状態時モータ停止用リミットスイッチ１９ｃは、三位置断路器１が切状態から接地状態に移行した後に駆動用のモータ１６を停止するものである。また、各モータ停止用リミットスイッチは動作していないときに接点が閉じており、モータ停止用カムによって動作すると接点が開くものである。 The on-state motor stop limit switch 19a stops the driving motor 16 after the three-position disconnector 1 has shifted from the off state to the on state. The motor stop limit switch 19b in the off state stops both the drive motor 16 in common after the three-position disconnector 1 has shifted from the on state to the off state and after the ground state has shifted to the off state. The number of limit switches used can be reduced by sharing. The limit switch 19c for stopping the motor in the grounding state is for stopping the driving motor 16 after the three-position disconnector 1 shifts from the disconnected state to the grounded state. Each motor stop limit switch is closed when the motor is not operating, and when the motor stop cam is operated, the contact is opened.
　図４において、メイン機構部３は、出力軸１３に固着されたゼネバ歯車１１と、ＥＳ操作軸１５に固着されゼネバ歯車１１と噛み合う操作レバー１２で構成されており、後で詳しく動作説明するが、操作レバー１２が１回転（３６０度）するとゼネバ歯車１１および出力軸１３が４５度回動する。 In FIG. 4, the main mechanism unit 3 includes a Geneva gear 11 fixed to the output shaft 13 and an operation lever 12 fixed to the ES operation shaft 15 and meshes with the Geneva gear 11. The operation will be described in detail later. When the operation lever 12 rotates once (360 degrees), the Geneva gear 11 and the output shaft 13 rotate 45 degrees.
　図２および図５ａならびに図５ｂにおいて、状態検出用リミットスイッチ部２は、カム軸６にカム軸用歯車７と状態検出用カム８が固着されており、カム軸６の周りに６０度ピッチに等分で軸方向に３段積に取付けられた入状態検出用リミットスイッチ９ａと切状態検出用リミットスイッチ９ｂと接地状態検出用リミットスイッチ９ｃがそれぞれ複数個配置されている。カム軸用歯車７はＥＳ操作軸１５に固着された歯車（図示せず）と噛み合うことで、ＥＳ操作軸１５が約１回転（３６０度）するとカム軸６が６０度回動する。なお、さらに多数の状態検出用リミットスイッチが必要な場合には、ＤＳ操作軸１４に連動させてもう一組同様のものを設置可能となっている。また、軸方向の積数は３段積に限定されるものではなく、必要に応じて複数段に設置されていればよく、段数を変更することで状態検出用リミットスイッチの数を調整できる。 2, 5 a, and 5 b, in the state detection limit switch unit 2, the cam shaft gear 7 and the state detection cam 8 are fixed to the cam shaft 6, and the cam shaft 6 has a pitch of 60 degrees around the cam shaft 6. A plurality of on-state detection limit switches 9a, off-state detection limit switches 9b, and ground-state detection limit switches 9c, which are equally divided into three stages in the axial direction, are arranged. The camshaft gear 7 meshes with a gear (not shown) fixed to the ES operation shaft 15 so that when the ES operation shaft 15 makes about one rotation (360 degrees), the camshaft 6 rotates 60 degrees. When a larger number of state detection limit switches are required, another set of the same switches can be installed in conjunction with the DS operation shaft 14. Further, the number of products in the axial direction is not limited to a three-stage product, and it is only necessary to be installed in a plurality of stages as needed, and the number of state detection limit switches can be adjusted by changing the number of stages.

　次に、断路器の操作装置１００の動作について説明する。
　図６ａから図６ｅはこの発明の実施の形態１における断路器の操作装置のメイン機構部の動作を説明する説明図、図７ａおよび図７ｂはこの発明の実施の形態１における断路器の操作装置の状態検出用リミットスイッチ部の動作を説明する説明図、図８はこの発明の実施の形態１における断路器の操作装置の入状態と切状態および接地状態の間の動作を説明する説明図である。 Next, the operation of the disconnector operating device 100 will be described.

FIGS. 7a and 7b are the disconnecting device operating device according to the first embodiment of the present invention. 8 is an explanatory diagram for explaining the operation of the state detection limit switch section, and FIG. 8 is an explanatory diagram for explaining the operation between the on state, the off state, and the ground state of the operating device for the disconnector according to the first embodiment of the present invention. is there.
　最初に切状態から入状態に操作する場合について説明する。切状態においては、図６ａに示すようにメイン機構部３の操作レバー１２はゼネバ歯車１１の中央の歯に噛み合っている。このとき状態検出用リミットスイッチ部２は図７ａに示すように状態検出用カム８が切状態検出用リミットスイッチ９ｂを動作させて接点は閉じている。
　この切状態で図９ａに示す入指令回路に入指令信号が入ると、切状態検出用リミットスイッチ９ｂが動作して閉じているため、モータ制御用リレーのｂ接点２１ｂと切状態検出用リミットスイッチ９ｂを介して切状態から入状態用電磁コンタクタ２２が励磁され、その接点２２ａが閉じるため、自己保持回路が働くこととなる。 First, the case of operating from the off state to the on state will be described. In the cut state, as shown in FIG. 6 a, the operation lever 12 of the main mechanism unit 3 meshes with the central tooth of the Geneva gear 11. At this time, as shown in FIG. 7A, the state detection limit switch unit 2 operates the cut state detection limit switch 9b by the state detection cam 8 to close the contact.
When an input command signal is input to the input command circuit shown in FIG. 9a in this OFF state, the OFF state detection limit switch 9b operates and closes, so the b contact 21b of the motor control relay and the OFF state detection limit switch The on-state electromagnetic contactor 22 is excited from the cut-off state via 9b and the contact 22a is closed, so that the self-holding circuit works.
　切状態から入状態用電磁コンタクタ２２の接点２２ａが閉じると、図１０に示すモータ制御回路は、切状態から入状態用電磁コンタクタの接点２２ａを介してモータ１６に電力が与えられ、モータ１６が回転してＥＳ操作軸１５に固着された操作レバー１２が反時計方向に回転する。操作レバー１２が図６ａの位置から図６ｂに示す位置まで回転すると、切状態検出用リミットスイッチ９ｂの接点は開くが、この時点では入状態時モータ停止用リミットスイッチ１９ａが動作していないため接点は閉じており、自己保持回路は継続されるためモータ１６が継続回転して操作レバー１２も反時計方向に回転する。 When the contact 22a of the electromagnetic contactor 22 for the on-state is closed from the cut-off state, the motor control circuit shown in FIG. 10 applies power to the motor 16 from the contact state 22a of the electromagnetic contactor for the on-state from the cut-off state. The operation lever 12 that is rotated and fixed to the ES operation shaft 15 rotates counterclockwise. When the operating lever 12 is rotated from the position shown in FIG. 6a to the position shown in FIG. 6b, the contact point of the cut-off state detection limit switch 9b is opened, but at this time, the contact point of the motor stop limit switch 19a is not operated. Is closed and the self-holding circuit is continued, so that the motor 16 continues to rotate and the operation lever 12 also rotates counterclockwise.
　操作レバー１２が図６ｂの位置から図６ｃの位置を経由し図６ｄの位置まで反時計方向に回転すると、操作レバー１２と噛み合わされたゼネバ歯車１１が４５度時計方向に回転して、出力軸１３を介して三位置断路器１の可動接触子（図示せず）を動作させて三位置断路器１を入状態にする。さらに操作レバー１２が反時計方向に回転していくと、状態検出用リミットスイッチ部２は状態検出用カム８が６０度回転した図７ｂに示す位置となり、状態検出用カム８が入状態検出用リミットスイッチ９ａを動作させる。 When the operation lever 12 rotates counterclockwise from the position of FIG. 6b to the position of FIG. 6d via the position of FIG. 6c, the Geneva gear 11 meshed with the operation lever 12 rotates 45 degrees clockwise, The movable contact (not shown) of the three-position disconnector 1 is operated via 13 to place the three-position disconnector 1 in the on state. When the operation lever 12 further rotates counterclockwise, the state detection limit switch section 2 is in the position shown in FIG. 7b in which the state detection cam 8 is rotated by 60 degrees, and the state detection cam 8 is in the on state detection state. The limit switch 9a is operated.
　その後、さらに操作レバー１２が反時計方向に回転して約１回転（３６０度）した図６ｅに示す状態になると、入状態時モータ停止用リミットスイッチ１９ａが動作して接点が開くことで自己保持回路は解除され、切状態から入状態用電磁コンタクタ２２の励磁も解除され、その接点２２ａが開いてモータ１６への電力供給が停止する。この状態で図１０に示すモータ制御回路において、モータ制御用リレーのａ接点２１ａと抵抗１７とサーマルリレー２０およびモータ１６の閉回路が成立し、モータ１６に発電制動がかかりモータ１６は停止する。 After that, when the operation lever 12 further rotates counterclockwise to reach the state shown in FIG. 6e, the motor stop limit switch 19a operates in the on state to open the contact so that self-holding occurs. The circuit is released, the excitation of the electromagnetic contactor 22 for the on state is released from the off state, the contact 22a is opened, and the power supply to the motor 16 is stopped. In this state, in the motor control circuit shown in FIG. 10, a closed circuit of the a contact 21a of the motor control relay, the resistor 17, the thermal relay 20, and the motor 16 is established, and the motor 16 is subjected to dynamic braking and the motor 16 stops.
　反対方向の入状態から切状態に操作する場合について説明する。入状態においては、図６ｅに示すようにメイン機構部３の操作レバー１２はゼネバ歯車１１の入側の歯に噛み合っている。このとき状態検出用リミットスイッチ部２は図７ｂに示すように状態検出用カム８が入状態検出用リミットスイッチ９ａを動作させて接点は閉じている。
　この切状態で図９ｂに示す切指令回路に切指令信号が入ると、入状態検出用リミットスイッチ９ａが動作して閉じているため、モータ制御用リレーのｂ接点２１ｂと入状態検出用リミットスイッチ９ａを介して入状態から切状態用電磁コンタクタ２４が励磁され、その接点２４ａが閉じるため、自己保持回路が働くこととなる。 A case will be described in which operation is performed from an on state in the opposite direction to a off state. In the engaged state, as shown in FIG. 6 e, the operation lever 12 of the main mechanism unit 3 is engaged with the teeth on the entry side of the Geneva gear 11. At this time, as shown in FIG. 7b, the state detection limit switch unit 2 is closed by the state detection cam 8 operating the on-state detection limit switch 9a.
When a cut command signal is input to the cut command circuit shown in FIG. 9b in this cut state, the on state detection limit switch 9a is operated and closed, so the b contact 21b of the motor control relay and the on state detection limit switch The electromagnetic contactor for off state 24 is excited from the on state via 9a and the contact 24a is closed, so that the self-holding circuit works.
　入状態から切状態用電磁コンタクタ２４の接点２４ａが閉じると、図１０に示すモータ制御回路は、入状態から切状態用電磁コンタクタの接点２４ａを介してモータ１６に電力が与えられ、モータ１６が回転してＥＳ操作軸１５に固着された操作レバー１２が時計方向に回転する。操作レバー１２が図６ｅの位置から図６ｄに示す位置まで回転すると、入状態検出用リミットスイッチ９ａの接点は開くが、この時点では切状態時モータ停止用リミットスイッチ１９ｂが動作していないため接点は閉じており、自己保持回路は継続されるためモータ１６が継続回転して操作レバー１２も時計方向に回転する。 When the contact 24a of the electromagnetic contactor 24 for the cut state is closed from the on state, the motor control circuit shown in FIG. 10 is supplied with electric power from the contact state 24a of the electromagnetic contactor for the cut state from the on state. The operation lever 12 rotated and fixed to the ES operation shaft 15 rotates in the clockwise direction. When the operating lever 12 is rotated from the position shown in FIG. 6e to the position shown in FIG. 6d, the contact of the limit switch 9a for detecting the on state is opened, but at this time, the limit switch 19b for stopping the motor is not operating in the off state. Is closed and the self-holding circuit is continued, so that the motor 16 continues to rotate and the operation lever 12 also rotates clockwise.
　操作レバー１２が図６ｄの位置から図６ｃの位置を経由し図６ｂの位置まで時計方向に回転すると、操作レバー１２と噛み合わされたゼネバ歯車１１が４５度反時計方向に回転して、出力軸１３を介して三位置断路器１の可動接触子（図示せず）を動作させて三位置断路器１を切状態にする。さらに操作レバー１２が時計方向に回転していくと、状態検出用リミットスイッチ部２は状態検出用カム８が６０度回転した図７ａに示す位置となり、状態検出用カム８が切状態検出用リミットスイッチ９ｂを動作させる。 When the operation lever 12 is rotated clockwise from the position of FIG. 6d to the position of FIG. 6b via the position of FIG. 6c, the Geneva gear 11 meshed with the operation lever 12 is rotated 45 degrees counterclockwise, and the output shaft The movable contact (not shown) of the three-position disconnector 1 is operated via 13 to put the three-position disconnector 1 in the disconnected state. When the operation lever 12 further rotates in the clockwise direction, the state detection limit switch unit 2 is in the position shown in FIG. 7a in which the state detection cam 8 is rotated by 60 degrees, and the state detection cam 8 is turned off. The switch 9b is operated.
　その後、さらに操作レバー１２が時計方向に回転して約１回転（３６０度）した図６ａに示す状態になると、切状態時モータ停止用リミットスイッチ１９ｂが動作して接点が開くことで自己保持回路は解除され、入状態から切状態用電磁コンタクタ２４の励磁も解除され、その接点２４ａが開いてモータ１６への電力供給が停止する。この状態で図１０に示すモータ制御回路において、モータ制御用リレーのａ接点２１ａと抵抗１７とサーマルリレー２０およびモータ１６の閉回路が成立し、モータ１６に発電制動がかかりモータ１６は停止する。 After that, when the operation lever 12 further rotates clockwise to about 1 rotation (360 degrees) and the state shown in FIG. 6a is reached, the motor stop limit switch 19b operates in the off state, and the contact opens to open the self-holding circuit. Is released, the excitation of the electromagnetic contactor 24 for the off state is released from the on state, the contact 24a is opened, and the power supply to the motor 16 is stopped. In this state, in the motor control circuit shown in FIG. 10, a closed circuit of the a contact 21a of the motor control relay, the resistor 17, the thermal relay 20, and the motor 16 is established, and the motor 16 is subjected to dynamic braking and the motor 16 stops.
　切状態から接地状態については図９ｃの接地指令回路のとおり動作し、接地状態から切状態については図９ｂの切指令回路の接地状態から切状態用電磁コンタクタ２３側の回路のとおり動作するが、詳細動作については上記説明と同様であり、説明を省略する。
　以上説明の動作状態をタイムチャート形式に図表化したものを図８に示す。図８では切状態を０度として、縦軸にゼネバ歯車１１の動き、横軸に操作レバー１２の動きを記入しており、横軸に合わせてモータ停止用リミットスイッチおよび状態検出用リミットスイッチの接点状況を記入している。 From the off state to the ground state, the circuit operates as the ground command circuit in FIG. 9c, and from the ground state to the off state, the circuit operates from the ground state of the off command circuit in FIG. 9b to the off-state electromagnetic contactor 23 side. The detailed operation is the same as described above, and the description is omitted.
FIG. 8 shows the operation state described above in the form of a time chart. In FIG. 8, the off state is 0 degree, the movement of the Geneva gear 11 is plotted on the vertical axis, and the movement of the operation lever 12 is plotted on the horizontal axis. The motor stop limit switch and the state detection limit switch are aligned with the horizontal axis. The contact status is entered.
　以上説明したように、本発明の断路器の操作装置においてはモータ停止用リミットスイッチとは別の位置に複数の状態検出用リミットスイッチを設けている。例えば従来のように状態検出用リミットスイッチでモータの停止機能も兼用させるようにすると、状態検出用リミットスイッチが複数設けられている場合には、リミットスイッチの個体差や組立ばらつきなどによって、モータが停止しても状態検出が完了していないリミットスイッチが発生する可能性があり、これを防止するためには状態検出用リミットスイッチの組立調整が難しくなるが、本発明のように、モータ停止用リミットスイッチとは別の位置に複数の状態検出用リミットスイッチを設けて、状態検出用リミットスイッチの動作完了後にモータ停止用リミットスイッチが動作するように構成することで、複数のリミットスイッチの個体差や組立ばらつきに影響されることなく、全ての状態検出用リミットスイッチの状態検出が可能となり、複数の状態検出用リミットスイッチの組立調整が容易となる。 As described above, the disconnector operating device of the present invention is provided with a plurality of state detection limit switches at positions different from the motor stop limit switch. For example, if the limit switch for state detection is also used for the motor stop function as in the past, if there are multiple state detection limit switches, the motor will There is a possibility that a limit switch that has not completed state detection even if it is stopped may occur. To prevent this, it becomes difficult to adjust the assembly of the state detection limit switch. By providing multiple state detection limit switches at different positions from the limit switch and configuring the motor stop limit switch to operate after completion of the operation of the state detection limit switch, individual differences between multiple limit switches Can detect the status of all status detection limit switches without being affected by assembly variations It becomes easy assembly and adjustment of the limit switch for detecting a plurality of states.
