Description

本発明は可動接触部を指定位置に停止させるために回動盤を停止させる停止手段を備えた接地型断路器に関する。   The present invention relates to a grounding type disconnector having stop means for stopping a turntable to stop a movable contact portion at a specified position.

一般に断路器は充電されている系統回路を開閉するので、負荷電流を開閉する遮断器とは異なり、系統回路の切り換え、区分、無負荷機器を系統回路より切り離す場合などに使用される。保守点検の場合には、その部分を電源から切り離し、確実に系統回路を開くために断路器を使用する。   In general, a disconnector opens and closes a charged system circuit, and therefore is used to switch a system circuit, classify, and disconnect a no-load device from the system circuit, unlike a circuit breaker that opens and closes a load current. In the case of maintenance inspection, disconnect the part from the power source and use a disconnector to open the system circuit reliably.

例えば、特許文献１に記載されている接地型断路部は、容器内に接地接触部と投入接触部との間に両接触部と接離する可動接触部を配置している。接地接触部は接地されており、また投入接触部は系統側電源に接続されている。可動接触部は負荷側電気機器を接続している。可動接触部を投入接触部に接続した状態で、系統側電源から負荷側電気機器に通電している。   For example, in the ground-type disconnection portion described in Patent Document 1, a movable contact portion that contacts and separates both contact portions is disposed between the ground contact portion and the input contact portion in the container. The ground contact portion is grounded, and the closing contact portion is connected to the system side power source. The movable contact portion connects the load-side electrical equipment. The load-side electrical device is energized from the system-side power source with the movable contact portion connected to the closing contact portion.

この負荷側電気機器を保守点検するには、可動接触部を回動し、可動接触部を投入接触部から切り離した後、更に可動接触部が回動し、断路位置を通過して接地接触部と接触し、負荷側電気機器に帯電された充電電流を接地に流し、電気的安全性を確保した状態で負荷側電気機器の保守点検を行う。   In order to maintain and inspect the load-side electrical equipment, the movable contact portion is rotated, and after the movable contact portion is separated from the closing contact portion, the movable contact portion is further rotated, passes through the disconnection position, and contacts the ground contact portion. The load-side electrical equipment is maintained and inspected while ensuring electrical safety by passing the charging current charged to the load-side electrical equipment to the ground.

可動接触部が投入接触部と接触する位置を投入位置と称し、可動接触部が投入接触部と離れ、電流を遮断する位置を断路位置と称している。断路位置では可動接触部が投入接触部と離れ、雷などで絶縁破壊を生じないこと及び負荷側回路で作業員が感電しない絶縁距離を取ることなどが必要である。また、可動接触部が接地接触部と接触する位置を接触位置と称する。断路位置は可動接触部が接触位置と投入位置との中間に位置すると共に、前述の条件を有することが必要である。可動接触部を投入位置、接地位置、断路位置の各位置で確実に停止維持することが必要な場合がある。
特開平１１−８９０２７号公報 The position where the movable contact portion comes into contact with the making contact portion is called a making position, and the position where the movable contact portion is separated from the making contact portion and cuts off the current is called the disconnecting position. At the disconnection position, the movable contact portion is separated from the closing contact portion, and it is necessary to prevent insulation breakdown due to lightning and the like, and to take an insulation distance at which the worker does not get an electric shock in the load side circuit. A position where the movable contact portion comes into contact with the ground contact portion is referred to as a contact position. The disconnecting position requires that the movable contact portion is located between the contact position and the closing position and has the above-described conditions. In some cases, it is necessary to reliably stop and maintain the movable contact portion at each of the closing position, the grounding position, and the disconnecting position.

図５に示すように、主軸４及び軸受部３３は上側から下側に貫通した貫通穴に締付ボルト３５Ａを挿入し、軸受部３３より露出した締付ボルト端に挿入されたナット３５Ｂを締付けることにより、主軸４と軸受部３３は締付ボルト３５Ａにより一体的に結合されている。従って、回動盤３２が回動すれば、それに応じて主軸４も同方向に回動する。軸受部３３の下側には駆動部３６が配置されていて、駆動部３６の駆動軸３６Ａにより回動盤３２を回動させているが、回動盤３２は手動により回動させることも可能である。   As shown in FIG. 5, the main shaft 4 and the bearing portion 33 insert a tightening bolt 35 </ b> A into a through hole penetrating from the upper side to the lower side, and tighten a nut 35 </ b> B inserted into the end of the tightening bolt exposed from the bearing portion 33. Thus, the main shaft 4 and the bearing portion 33 are integrally coupled by the fastening bolt 35A. Therefore, if the turntable 32 rotates, the main shaft 4 also rotates in the same direction accordingly. A drive unit 36 is disposed below the bearing unit 33, and the rotation plate 32 is rotated by the drive shaft 36A of the drive unit 36. However, the rotation plate 32 can be manually rotated. It is.

図２に示すように、駆動軸３６Ａの左側端にはモータ３７のピニオンギア３７Ａと係合しているギア３６Ｂが設けられていて、駆動軸３６Ａはギア３６Ｂの回転に応じて同方向に回転する。駆動軸３６Ａと第２駆動軸３６Ｃは、ユニバーサルジョイント３８を介して接続されている。第２駆動軸３６Ｃは図６に示す雌ネジ穴３６Ｄに挿入されている。   As shown in FIG. 2, a gear 36B engaged with the pinion gear 37A of the motor 37 is provided at the left end of the drive shaft 36A, and the drive shaft 36A rotates in the same direction according to the rotation of the gear 36B. To do. The drive shaft 36A and the second drive shaft 36C are connected via a universal joint 38. The second drive shaft 36C is inserted into the female screw hole 36D shown in FIG.

雌ネジ穴３６Ｄは回動盤軸３６Ｅの長手方向に対し直角方向に貫通している。回動盤軸３６Ｅは回動盤３２の平面部３４の右側面から締付ボルト３５Ａに達する手前までの位置まで伸びている。この雌ネジ穴３６Ｄ内面に形成したネジ溝（図示省略）に第２駆動軸３６Ｂの雄ネジ３６Ｙを螺合させた状態で第２駆動軸３６Ｃの先端部は雌ネジ穴３６Ｄに挿入されている。   The female screw hole 36D penetrates in a direction perpendicular to the longitudinal direction of the rotating disk shaft 36E. The turntable shaft 36E extends from the right side surface of the flat portion 34 of the turntable 32 to a position before reaching the fastening bolt 35A. The tip of the second drive shaft 36C is inserted into the female screw hole 36D in a state where the male screw 36Y of the second drive shaft 36B is screwed into a screw groove (not shown) formed in the inner surface of the female screw hole 36D. .

図５に示すように、駆動軸３６Ａ及びユニバーサルジョイント３８並びに第２駆動軸３６Ｃを時計方向（Ｘ１方向）に回転させると、第２駆動軸３６Ｃに雌ネジ穴３６Ｄが螺合されている回動盤軸３６Ｅが第２駆動軸３６Ｃの長さ方向に移動して回動盤３２及び主軸４が回動する。回動盤３２が回動するのに応じて第２駆動軸３６Ｃ及び回動盤３２はＹ方向へ降下する。第２駆動軸３６Ｃの降下は図２の降下防止支持金具３９により支持される。降下防止支持金具３９は支持板２に取付けられている。第２駆動軸３６ＣのＹ方向への降下による変移移動はユニバーサルジョイント３８により吸収されるので、第２駆動軸３６Ｃをスムーズに回転することが出来る。   As shown in FIG. 5, when the drive shaft 36A, the universal joint 38, and the second drive shaft 36C are rotated clockwise (X1 direction), the rotation in which the female screw hole 36D is screwed to the second drive shaft 36C. The disk shaft 36E moves in the length direction of the second drive shaft 36C, and the rotating disk 32 and the main shaft 4 rotate. As the turntable 32 rotates, the second drive shaft 36C and the turntable 32 descend in the Y direction. The lowering of the second drive shaft 36C is supported by the lowering prevention support fitting 39 of FIG. The lowering prevention support fitting 39 is attached to the support plate 2. Since the displacement movement due to the lowering of the second drive shaft 36C in the Y direction is absorbed by the universal joint 38, the second drive shaft 36C can be smoothly rotated.

ユニバーサルジョイント３８を使用しなければ、第２駆動軸３６Ｃが回転しないばかりか、又は回転しても余分な負荷荷重が掛かり、動力を大きくした駆動部を必要とする欠点を生じるが、本実施例ではユニバーサルジョイント３８を使用した分だけ、動力の小さいモータ３７及び駆動部３６を使用でき、駆動部３６の消費工ネルギーを少なくした所謂、省エネルギー化を計ることができる。   If the universal joint 38 is not used, not only the second drive shaft 36C does not rotate, but even if the second drive shaft 36C rotates, an extra load is applied, which causes a disadvantage that a drive unit with increased power is required. Thus, the motor 37 and the drive unit 36 with small power can be used as much as the universal joint 38 is used, and so-called energy saving can be achieved by reducing the consumption energy of the drive unit 36.

また回動盤３２を回動するには回動盤の厚み面つまり周面部分の一部にウォームホイールの歯形を形成し、このウォームホイールの歯形をモータのピニオンギアと係合するようにすれば、構成部品点数を前述の駆動軸を使用した構成部品より少なくする事が出来る。   In order to turn the turntable 32, a tooth shape of the worm wheel is formed on a part of the thickness surface of the turntable, that is, a part of the peripheral surface, and the tooth shape of the worm wheel is engaged with the pinion gear of the motor. For example, the number of components can be made smaller than that of components using the drive shaft described above.

このように、回動盤３２及び主軸４を図２に示す時計方向（Ｘ１方向）に回動すると、可動接触部７も同方向に回動し、投入接触部１０に投入される。前述とは反対に反時計方向Ｘ２に回動すると、可動接触部７は投入位置Ａから断路位置Ｂを経て接地接触部２２に接触し、接地位置Ｃで停止する。   As described above, when the turntable 32 and the main shaft 4 are turned in the clockwise direction (X1 direction) shown in FIG. 2, the movable contact portion 7 is also turned in the same direction and is put into the closing contact portion 10. When rotating in the counterclockwise direction X2 contrary to the above, the movable contact portion 7 comes into contact with the ground contact portion 22 from the closing position A through the disconnection position B, and stops at the ground contact position C.

可動接触部７を各位置で停止維持するための停止手段として本実施の形態においては、図５に示すように、回動盤３２の平面部３４に前記主軸４を中心とする円弧位置に所定間隔をもって３個の停止穴を形成した。各停止穴は下側から上側に向かって投入穴３２Ａ、断路穴３２Ｂ、接地穴３２Ｃとなっている。これらの各穴３２Ａ〜３２Ｃには係合手段、例えば電磁石（ソレノイド）４０のプランジャー４１が挿入される。例えば図４、図５に示すように、プランジャー４１が断路穴３２Ｂに挿入されて回動盤３２が停止すると可動接触部７は断路位置Ｂで停止する。プランジャー４１が投入穴３２Ａに挿入されて回動盤３２が停止すると可動接触部７は投入位置Ａで停止する。また、プランジャー４１が接地穴３Ｃに挿入されて回動盤３２が停止すると可動接触部７は接地位置Ｃに停止する。   In this embodiment, as a stopping means for stopping and maintaining the movable contact portion 7 at each position, as shown in FIG. 5, a predetermined circular arc position centered on the main shaft 4 is provided on the flat portion 34 of the turntable 32. Three stop holes were formed at intervals. Each stop hole is formed as a charging hole 32A, a disconnecting hole 32B, and a grounding hole 32C from the lower side to the upper side. Engaging means, for example, a plunger 41 of an electromagnet (solenoid) 40 is inserted into each of the holes 32A to 32C. For example, as shown in FIGS. 4 and 5, when the plunger 41 is inserted into the disconnect hole 32 </ b> B and the turntable 32 stops, the movable contact portion 7 stops at the disconnect position B. When the plunger 41 is inserted into the insertion hole 32A and the turntable 32 stops, the movable contact portion 7 stops at the insertion position A. Further, when the plunger 41 is inserted into the grounding hole 3C and the turntable 32 stops, the movable contact portion 7 stops at the grounding position C.

上述のように回動盤３２は指定した各位置に相当する個所に穴や突起、溝部、磁石等の停止手段を設け、この停止手段にプランジャー、動作棒などの係合手段を係合することにより回動盤は指定位置で停止する。   As described above, the turntable 32 is provided with stop means such as holes, protrusions, grooves, and magnets at locations corresponding to the designated positions, and engaging means such as plungers and operating bars are engaged with the stop means. As a result, the turntable stops at the designated position.

図５に示すように、電磁石４０は駆動室内の床板に設けた取付板４２に締付ネジ４２Ａにより固定されている。取付板４２Ａの下側の貫通穴４２Ｂには駆動軸３６Ａが挿通されている。   As shown in FIG. 5, the electromagnet 40 is fixed to a mounting plate 42 provided on a floor plate in the driving chamber by a fastening screw 42A. A drive shaft 36A is inserted through the lower through hole 42B on the mounting plate 42A.

電磁石内のプランジャー４１は、電磁コイル４３による励磁しない時には図７に示すように、バネ４０Ａの伸張力により、先端部４１Ｃが投入穴３２Ａ、断路穴３２Ｂ、接地穴３２Ｃから抜け出た状態になっている。そして、電磁コイル４３を励磁したときに、図８に示すように、プランジャー４１はバネ４０Ａを圧縮しながら先端部４１Ｃが投入穴３２Ａ、断路穴３２Ｂ、接地穴３２Ｃのいずれか一つ穴に挿入される。電磁コイル４３による励磁を解くと、バネ４０Ａの圧縮エネルギーが釈放され、その伸張力によってプランジャー４１の先端部４１Ｃは前記穴より脱出し、回動盤３２を回動可能な位置に移動する。   As shown in FIG. 7, when the plunger 41 in the electromagnet is not excited by the electromagnetic coil 43, the distal end portion 41C comes out of the insertion hole 32A, the disconnecting hole 32B, and the grounding hole 32C by the extension force of the spring 40A. ing. When the electromagnetic coil 43 is energized, as shown in FIG. 8, the plunger 41 is compressed into the spring 40A and the tip 41C is inserted into any one of the insertion hole 32A, the disconnecting hole 32B, and the grounding hole 32C. The When the excitation by the electromagnetic coil 43 is released, the compression energy of the spring 40A is released, and the distal end portion 41C of the plunger 41 escapes from the hole by the extension force, and moves the turntable 32 to a rotatable position.

図７に示すように、プランジャー４１は軸部４１Ａより直径の小さい環状の凹部つまり絞り部（掛部）４１Ｂを有している。プランジャー４１に対して手動レバー４５が交差するように配置されている。   As shown in FIG. 7, the plunger 41 has an annular concave portion, that is, a throttle portion (hanging portion) 41B having a diameter smaller than that of the shaft portion 41A. A manual lever 45 is arranged to intersect the plunger 41.

手動レバー４５は、誤って中央制御部より投入指令がなされた場合にプランジャー４１の移動を阻止し、具体的には接地接触部側で保守点検中に可動接触部７が断路位置や投入位置に移動することのないようにして作業員の安全性を確保するものである。   The manual lever 45 prevents the movement of the plunger 41 when a closing command is mistakenly given by the central control unit. Specifically, the movable contact portion 7 is disconnected or closed during maintenance and inspection on the ground contact portion side. The safety of the workers is ensured so that they do not move to

図９、図１０に示すように、手動レバー４５の一端側４５Ａは主軸２に回転自在に取付けられていると共に、他端側の手動操作部４５Ｂは操作盤３１に設けた開口部４８から外部に突出している。手動レバー４５にはプランジャー４１の軸部４１Ａを通過させる通過穴４５Ｃと、絞り部４１Ｂのみを通過させる阻止穴４５Ｄとが形成されている。通過穴４５Ｃと阻止穴４５Ｄとは連通しており、絞り部４１Ｂのみが通過穴４５Ｃと阻止穴４５Ｄとの間を通過することができる。駆動室内面３０Ａと手動レバー４５との間には引張バネ４６が設けられている共に、手動レバー４５はストツバー４７により回動を制限されている。ストッパー４７は駆動室内に支持されている。なお、手動レバー４５は駆動室内の支持軸に回転自在に装着しても良い。   As shown in FIGS. 9 and 10, one end side 45 </ b> A of the manual lever 45 is rotatably attached to the main shaft 2, and the manual operation unit 45 </ b> B on the other end side is externally provided from an opening 48 provided in the operation panel 31. Protruding. The manual lever 45 is formed with a passage hole 45C through which the shaft part 41A of the plunger 41 passes and a blocking hole 45D through which only the throttle part 41B passes. The passage hole 45C and the blocking hole 45D communicate with each other, and only the throttle portion 41B can pass between the passage hole 45C and the blocking hole 45D. A tension spring 46 is provided between the drive chamber inner surface 30 </ b> A and the manual lever 45, and the manual lever 45 is restricted from rotating by a stock bar 47. The stopper 47 is supported in the drive chamber. The manual lever 45 may be rotatably mounted on a support shaft in the drive chamber.

次に、手動レバー４５の動作を説明する。図１１に示すように、手動レバー４５の手動操作部４５Ｂが開口部４８の上側に位置している場合は、図９に示すように、プランジャー４１の軸部４１Ａは通過穴４５Ｃに位置して、回動盤３２側に移動可能な状態になっている。従って、この状態でプランジャー４１を右方に移動させれば、図８に示すように、プランジャー４１の先端部４１Ｃが例えば接地穴３２Ｃに挿入されて位置決めされた状態になると共に、絞り部４１Ｂが手動レバー４５の位置に移動して来る。   Next, the operation of the manual lever 45 will be described. As shown in FIG. 11, when the manual operation portion 45B of the manual lever 45 is positioned above the opening 48, the shaft portion 41A of the plunger 41 is positioned in the passage hole 45C as shown in FIG. Thus, it is movable to the turntable 32 side. Therefore, if the plunger 41 is moved to the right in this state, as shown in FIG. 8, the tip 41C of the plunger 41 is inserted and positioned in the grounding hole 32C, for example, and the throttle portion 41B moves to the position of the manual lever 45.

そこで、図１１に破線で示すように、手動レバー４５の手動操作部４５Ｂを開口部４８の上側から下側に降下させると、手動レバー４５は主軸４を支点として反時計方向に回動する（図９、図１０参照）。その時、引張バネ４６はエネルギーを蓄積するように伸ばされる。そして、図１１に示すように、手動レバー４５の手動操作部４５Ｂを開口部４８のフック部（段部）４８Ａに係合し、引張バネ４６のエネルギーを蓄積する。   Therefore, as shown by a broken line in FIG. 11, when the manual operation portion 45B of the manual lever 45 is lowered from the upper side to the lower side of the opening 48, the manual lever 45 rotates counterclockwise about the main shaft 4 ( 9 and 10). At that time, the tension spring 46 is extended to store energy. Then, as shown in FIG. 11, the manual operation part 45 </ b> B of the manual lever 45 is engaged with the hook part (step part) 48 </ b> A of the opening part 48, and the energy of the tension spring 46 is accumulated.

手動操作部４５Ｂとフック４８Ａとの係合を解くと、引張バネ４６の蓄積エネルギーが釈放され、手動レバー４５は前述と反対方向に回動してストッパー４７に当接して回動を阻止され、手動レバー４５は開始時の位置にリセットされ、手動操作部４５Ｂは開口部４８の上側に移動すると共に、プランジャー４１が通過穴４５Ｃを通過し得る状態になる。   When the manual operation portion 45B and the hook 48A are disengaged, the stored energy of the tension spring 46 is released, and the manual lever 45 rotates in the opposite direction to the above to contact the stopper 47 and is prevented from rotating. The manual lever 45 is reset to the starting position, the manual operation unit 45B moves to the upper side of the opening 48, and the plunger 41 can pass through the passage hole 45C.

上述したように実施例では、例えばプランジャー４１の先端部４１Ｃが接地穴３２Ｃに挿入されると、図８に示すように、絞り部４１Ｂが手動レバー４５と交差する位置に移動してくる。従って、手動レバー４５を操作して絞り部４１Ｂを阻止穴４５Ｄ内に挿入することが可能になる。絞り部４１Ｂを阻止穴４５Ｄ内に挿入することによりにプランジャー４１の移動を阻止する。従って、この状憩で誤って中央制御部より投入指令がなされ、電磁石４０を励磁し、プランジャー４１が移動しようとしても、軸部４１Ａの端部が手動レバー４５の側面に接触して移動できず接地接触部側で保守点検中である作業員の安全性を確保することができる。つまり、誤動作により作業員の安全性を確保することが出来る。   As described above, in the embodiment, for example, when the distal end portion 41C of the plunger 41 is inserted into the grounding hole 32C, the throttle portion 41B moves to a position intersecting with the manual lever 45 as shown in FIG. Accordingly, it is possible to operate the manual lever 45 to insert the throttle portion 41B into the blocking hole 45D. The movement of the plunger 41 is blocked by inserting the throttle portion 41B into the blocking hole 45D. Therefore, even when the insertion command is mistakenly given by the central control unit due to this break, the electromagnet 40 is excited and the plunger 41 tries to move, the end portion of the shaft portion 41A can contact the side surface of the manual lever 45 and move. Therefore, it is possible to ensure the safety of workers who are in maintenance inspection on the ground contact part side. That is, the safety of the worker can be ensured by malfunction.

以上のように、本発明の接地型断路器よれば、外部からの動作指令により係合手段を回動盤の停止手段に係合し、回動盤を停止するようにした簡単な操作機構で可動接触部を指定位置で確実に停止することができるようになった。   As described above, according to the grounding type disconnector of the present invention, a simple operation mechanism that engages the engaging means with the stop means of the turntable by an operation command from the outside and stops the turntable. The movable contact part can be stopped reliably at the specified position.

またプランジャーに代えて操作棒を使用して、作業員の手動により操作棒を各穴に出入り、つまり着脱するようにしても良い。電磁石に、励磁電流と、これと反対の直流電流を通電してプランジャーを往復移動させる電磁反発型電磁石を使用すれば、バネ４０Ａは必要としない。   In addition, an operation rod may be used instead of the plunger, and the operation rod may be moved in and out of each hole by an operator manually, that is, attached or detached. If an electromagnetic repulsion type electromagnet that reciprocates the plunger by energizing the electromagnet with an exciting current and a direct current opposite thereto, the spring 40A is not necessary.

要は外部からの動作指令により係合手段が停止手段に係合し、回動盤を指定位置で停止できれば良い。外部からの動作指令には手動による動作指令、電気及び通信指令などの指令を含む。   In short, it is only necessary that the engaging means is engaged with the stopping means by an operation command from the outside, and the turntable can be stopped at the specified position. External operation commands include manual operation commands, electrical and communication commands, and the like.

以上のように本発明では、駆動部３６の回転に応じ回動盤３２が回動し、この回動盤３２の回動により主軸４を回動し、可動接触部７を投入位置Ａ、断路位置Ｂ、接地位置Ｃに移動した距離と同じ距離に相当する個所の回動盤に投入穴３２Ａ，断路穴３２Ｂ，接地穴３２Ｃを設け、例えば可動接触部７を接地位置３２Ｃで停止している時には、回動盤３２も可動接触部７と同じ距離だけ回動して接地穴３２Ｃにプランジャー４１を挿入し、回動盤３２の回動を停止し、可動接触部７を接地接触部２２と接触した接地位置Ｃで確実に停止させることが出来る。その他の投入位置Ａ及び断路位置Ｂも前述と同じであるから説明を省略する。   As described above, in the present invention, the turntable 32 is rotated according to the rotation of the drive unit 36, the main shaft 4 is rotated by the rotation of the turntable 32, and the movable contact portion 7 is connected to the loading position A, disconnection. A turning hole 32A, a disconnection hole 32B, and a grounding hole 32C are provided in a rotating board corresponding to the same distance as the distance moved to the position B and the grounding position C. For example, the movable contact portion 7 is stopped at the grounding position 32C. Sometimes, the turntable 32 also turns the same distance as the movable contact portion 7 to insert the plunger 41 into the grounding hole 32C, stops the turntable 32, and moves the movable contact portion 7 to the ground contact portion 22. Can be reliably stopped at the ground contact position C in contact with. The other charging position A and disconnecting position B are also the same as described above, and the description thereof is omitted.

このように、回動盤３２に可動接触部７と停止手段とを設けるという簡単な操作機構で可動接触部の停止位置を回動盤により確実に停止することが出来る。   Thus, the stop position of the movable contact portion can be reliably stopped by the turntable by a simple operation mechanism in which the turntable 32 is provided with the movable contact portion 7 and the stop means.

更に、回動盤３２は盤を使用することにより、回動盤３２に各穴３２Ａ〜３２Ｃを形成することができ、回動盤３２に対してプランジャー４１を直角方向に配置できるようにようになり、プランジャー４１を各穴３２Ａ〜３２Ｃに出入りさせるだけでよく、係合手段の操作機構を簡素化することが出来るようになった。   Further, by using a rotating plate 32, each of the holes 32A to 32C can be formed in the rotating plate 32 so that the plunger 41 can be arranged in a direction perpendicular to the rotating plate 32. Thus, the plunger 41 only needs to be moved in and out of the holes 32A to 32C, and the operation mechanism of the engaging means can be simplified.

以上のように、本発明の接地型断路器よれば、外部からの動作指令により係合手段を回動盤の停止手段に係合し、回動盤を停止するようにした簡単な操作機構で可動接触部を指定位置で確実に停止することができるようになった。   As described above, according to the grounding type disconnector of the present invention, a simple operation mechanism that engages the engaging means with the stop means of the turntable by an operation command from the outside and stops the turntable. The movable contact part can be stopped reliably at the specified position.
