Description

本発明の実施形態は、引出形の真空遮断器を金属閉鎖形スイッチギヤに出し入れする真空遮断器の出入装置に関する。   Embodiments of the present invention relate to a vacuum circuit breaker entrance / exit device that allows a drawer-type vacuum circuit breaker to enter and exit a metal closed switchgear.

従来、引出形の真空遮断器には、真空遮断器を移動させる出入装置が設けられ、金属閉鎖形スイチギヤの主回路に接続または断路させられるようになっている（例えば、特許文献１参照。）。   Conventionally, a pull-out type vacuum circuit breaker is provided with an input / output device for moving the vacuum circuit breaker, and is connected to or disconnected from the main circuit of the metal closed switch gear (see, for example, Patent Document 1). .

この種の出入装置は、図４、図５に示すように、真空遮断器部１ａと主回路ユニット部１ｂで構成されている。図４は、真空遮断器部１ａが主回路ユニット部１ｂから離れた断路位置、図５は、これらが接続された接続位置を示す。   As shown in FIGS. 4 and 5, this type of access device includes a vacuum circuit breaker unit 1 a and a main circuit unit unit 1 b. 4 shows the disconnection position where the vacuum circuit breaker unit 1a is separated from the main circuit unit unit 1b, and FIG. 5 shows the connection position where these are connected.

真空遮断器部１ａには、ベース板２に操作機構部３が固定されている。操作機構部３には、真空バルブ４を用いた遮断部５が固定され、遮断部５に上部接触子６と下部接触子７が設けられている。ベース板２には、回転自在の車輪８が設けられている。また、出入ねじ棒９を回転自在に固定する固定架台１０が固定されている。出入ねじ棒９は、端部９ａとねじ部９ｂで構成され、端部９ａにハンドル１１の回転部を嵌め込み回転させることができる。   An operation mechanism unit 3 is fixed to the base plate 2 in the vacuum circuit breaker unit 1a. A shut-off unit 5 using a vacuum valve 4 is fixed to the operation mechanism unit 3, and an upper contact 6 and a lower contact 7 are provided on the shut-off unit 5. The base plate 2 is provided with rotatable wheels 8. Moreover, the fixed mount 10 which fixes the entrance / exit screw rod 9 rotatably is fixed. The loading / unloading screw rod 9 is composed of an end portion 9a and a screw portion 9b, and a rotating portion of the handle 11 can be fitted into the end portion 9a and rotated.

主回路ユニット部１ｂには、床板１２とこれに略直角に固定された仕切板１３が設けられている。仕切板１３には、上部接触子６と接離する上部主回路断路部１４と、下部接触子７と接離する下部主回路断路部１５が貫通固定されている。上部主回路断路部１４と下部主回路断路部１５の背面側には、金属閉鎖形スイッチギヤの主回路が接続される。床板１２には、出入ねじ棒９の軸方向に出入ねじ受け１６が固定されている。なお、主回路ユニット部１ｂを金属閉鎖形スイッチギヤに取付けると、出入ねじ棒９の端部９ａ近傍に一点鎖線で示す正面扉１７が位置する。   The main circuit unit portion 1b is provided with a floor plate 12 and a partition plate 13 fixed at a substantially right angle thereto. An upper main circuit disconnecting portion 14 that contacts and separates from the upper contact 6 and a lower main circuit disconnecting portion 15 that contacts and separates from the lower contact 7 are fixed to the partition plate 13 by penetration. On the back side of the upper main circuit disconnecting portion 14 and the lower main circuit disconnecting portion 15, a main circuit of a metal closed switchgear is connected.

FIG. 1 is a side view showing the configuration of a vacuum circuit breaker entrance / exit device according to Embodiment 1 of the present invention, and FIG. 2 is a diagram for explaining the operation of the vacuum circuit breaker entrance / exit device according to Embodiment 1 of the present invention. is there. In addition, in each figure, the same code | symbol was attached | subjected about the component similar to the past.

図１、図２に示すように、真空遮断器の出入装置は、真空遮断器部１ａと主回路ユニット部１ｂで構成されている。図１は、真空遮断器部１ａが主回路ユニット部１ｂから離れた断路位置、図２は、これらが接続された接続位置を示す。   As shown in FIGS. 1 and 2, the vacuum circuit breaker entrance / exit device includes a vacuum circuit breaker section 1a and a main circuit unit section 1b. FIG. 1 shows a disconnection position where the vacuum circuit breaker unit 1a is separated from the main circuit unit unit 1b, and FIG. 2 shows a connection position where these are connected.

真空遮断器部１ａには、ベース板２に操作機構部３が固定されている。操作機構部３には、真空バルブ４を用いた遮断部５が固定され、この遮断部５に上部接触子６と下部接触子７が設けられている。ベース板２には、回転自在の車輪８が設けられている。また、出入ねじ棒９のねじ部９ｂが螺合する出入ねじ受け１６が図示右方向のベース板２端部に固定されている。出入ねじ棒９は、端部９ａと前記ねじ部９ｂで構成され、端部９ａにハンドル１１の回転部を嵌め込み回転させることができる。   An operation mechanism unit 3 is fixed to the base plate 2 in the vacuum circuit breaker unit 1a. A shut-off portion 5 using a vacuum valve 4 is fixed to the operation mechanism portion 3, and an upper contact 6 and a lower contact 7 are provided on the shut-off portion 5. The base plate 2 is provided with rotatable wheels 8. Further, an input / output screw receiver 16 into which the screw portion 9b of the input / output screw rod 9 is screwed is fixed to the end of the base plate 2 in the right direction in the figure. The loading / unloading screw rod 9 is composed of an end portion 9a and the screw portion 9b, and a rotating portion of the handle 11 can be fitted into the end portion 9a and rotated.

主回路ユニット部１ｂには、床板１２とこれに略直角に固定された仕切板１３が設けられている。仕切板１３には、上部接触子６と接離する上部主回路断路部１４と、下部接触子７と接離する下部主回路断路部１５が貫通固定されている。上部主回路断路部１４と下部主回路断路部１５の背面側には、金属閉鎖形スイッチギヤの主回路が接続される。床板１２には、出入ねじ棒９を回転自在に固定する固定架台１０が固定されている。なお、主回路ユニット部１ｂを金属閉鎖形スイッチギヤに取付けると、出入ねじ棒９の端部９ａ近傍に一点鎖線で示す正面扉１７が位置する。   The main circuit unit portion 1b is provided with a floor plate 12 and a partition plate 13 fixed at a substantially right angle thereto. An upper main circuit disconnecting portion 14 that contacts and separates from the upper contact 6 and a lower main circuit disconnecting portion 15 that contacts and separates from the lower contact 7 are fixed to the partition plate 13 by penetration. On the back side of the upper main circuit disconnecting portion 14 and the lower main circuit disconnecting portion 15, a main circuit of a metal closed switchgear is connected. A fixed base 10 is fixed to the floor plate 12 so as to fix the access screw rod 9 rotatably. When the main circuit unit portion 1b is attached to the metal closed type switchgear, the front door 17 indicated by a one-dot chain line is located in the vicinity of the end portion 9a of the input / output screw rod 9.

次に、真空遮断器部１ａの出入操作について説明する。図１の断路位置において、正面扉１７の貫通孔にハンドル１１を挿入し、端部９ａに嵌め込み、出入ねじ棒９を回転させると、ねじ部９ｂが出入ねじ受け１６内を回転する。すると、真空遮断器部１ａは、床板１２上を図示右方向に移動し、接触子６、７がそれぞれ主回路断路部１４、１５に接触し、図２に示す接続位置にすることができる。出入ねじ棒９を上記と逆に回転させると、図示左方向に移動し、断路位置にすることができる。   Next, the operation for entering and exiting the vacuum circuit breaker unit 1a will be described. 1, when the handle 11 is inserted into the through hole of the front door 17 and fitted into the end portion 9a and the input / output screw rod 9 is rotated, the screw portion 9b rotates in the input / output screw receiver 16. Then, the vacuum circuit breaker part 1a moves on the floor board 12 in the right direction in the figure, and the contacts 6 and 7 come into contact with the main circuit disconnecting parts 14 and 15, respectively, so that the connection position shown in FIG. When the loading / unloading screw rod 9 is rotated in the reverse direction to the above, it can move in the left direction in the figure and can be set to the disconnecting position.

なお、組立においては、出入ねじ受け１６に出入ねじ棒９のねじ部９ｂを螺合させておき、端部９ａが固定架台１０を通り過ぎるまで一旦、真空遮断器部１ａを図示右方向に移動させる。そして、端部９ａが固定架台１０を貫通するように図示左方向に戻せば、図１の断路位置にすることができる。   In assembling, the threaded portion 9b of the threading rod 9 is screwed into the loading / unloading screw receiver 16, and the vacuum circuit breaker portion 1a is once moved rightward in the drawing until the end portion 9a passes through the fixed base 10. . If the end portion 9a is returned to the left in the drawing so as to penetrate the fixed mount 10, the disconnection position in FIG. 1 can be obtained.

これにより、真空遮断器部１ａを断路位置から接続位置にしても、出入ねじ棒９は同様の位置であり、端部９ａに嵌め込むハンドル１１に治具などを連結する必要がなくなる。このため、正面扉１７外から、容易に回転操作を行うことができ、操作性を向上させることができる。   Thereby, even if the vacuum circuit breaker part 1a is moved from the disconnection position to the connection position, the input / output screw rod 9 is in the same position, and it is not necessary to connect a jig or the like to the handle 11 fitted into the end part 9a. For this reason, rotation operation can be easily performed from the outside of the front door 17, and operativity can be improved.

上記実施例１の真空遮断器の出入装置によれば、主回路ユニット１ｂの床板２に出入ねじ棒９を回転自在に固定する固定架台１０を固定し、真空遮断器部１ａのベース板２に出入ねじ棒９のねじ部９ｂが螺合する出入ねじ受け１６を固定しているので、真空遮断器部１ａを移動させても出入ねじ棒９は移動せず、正面扉１７外からのハンドル１１の回転操作が容易となり、操作性を向上させることができる。   According to the vacuum circuit breaker entrance / exit device of the first embodiment, the fixed base 10 for rotatably fixing the access screw rod 9 is fixed to the floor plate 2 of the main circuit unit 1b, and the base plate 2 of the vacuum circuit breaker section 1a is fixed. Since the input / output screw receiver 16 to which the screw portion 9b of the input / output screw rod 9 is screwed is fixed, the input / output screw rod 9 does not move even if the vacuum circuit breaker portion 1a is moved, and the handle 11 from the outside of the front door 17 is provided. Can be easily rotated, and operability can be improved.

次に、本発明の実施例２に係る真空遮断器の出入装置を図３を参照して説明する。図３は、本発明の実施例２に係る真空遮断器の出入装置の構成を示す側面図である。なお、この実施例２が実施例１と異なる点は、インターロック機構を設けたことである。図３において、実施例１と同様の構成部分においては、同一符号を付し、その詳細な説明を省略する。   Next, a description will be given of a vacuum circuit breaker access device according to Embodiment 2 of the present invention with reference to FIG. FIG. 3 is a side view showing the configuration of the access device for the vacuum circuit breaker according to the second embodiment of the present invention. The second embodiment differs from the first embodiment in that an interlock mechanism is provided. In FIG. 3, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図３に示すように、出入ねじ受け１６を操作機構部３側のベース板２に固定し、出入ねじ受け１６に嵌合台１８を固定している。また、嵌合台１８に嵌め込まれる移動自在のインターロック棒１９を操作機構部３に設けている。ベース板２の背面側先端には、出入ねじ棒９が長くなるので、固定架台１０と同様の固定架台２０を設けている。   As shown in FIG. 3, the input / output screw receiver 16 is fixed to the base plate 2 on the operation mechanism unit 3 side, and the fitting base 18 is fixed to the input / output screw receiver 16. In addition, a movable interlock rod 19 fitted in the fitting base 18 is provided in the operation mechanism unit 3. Since the access screw rod 9 is elongated at the rear end of the base plate 2, a fixed mount 20 similar to the fixed mount 10 is provided.

真空遮断器部１ａを移動させるときには、インターロック棒１９を操作し、嵌合台１８に嵌め込み、出入ねじ棒９を回転させる。インターロック棒１９には、電気的、機械的なインターロックを連結することができる。   When moving the vacuum circuit breaker unit 1a, the interlock rod 19 is operated, fitted into the fitting base 18, and the access screw rod 9 is rotated. An electrical and mechanical interlock can be connected to the interlock rod 19.

上記実施例２の真空遮断器の出入装置によれば、実施例１による効果のほかに、真空遮断器部１ａを移動させるときの誤操作を防止することができる。   According to the vacuum circuit breaker entry / exit device of the second embodiment, in addition to the effects of the first embodiment, it is possible to prevent an erroneous operation when the vacuum circuit breaker unit 1a is moved.

以上述べたような実施形態によれば、真空遮断器を移動させるための出入装置を構成する出入ねじ棒を主回路ユニット側に回転自在に固定しているので、真空遮断器を移動させても出入ねじ棒が移動せず、正面扉外から容易に操作することができる。   According to the embodiment as described above, since the input / output screw rod constituting the input / output device for moving the vacuum circuit breaker is rotatably fixed to the main circuit unit side, the vacuum circuit breaker can be moved. The screw rod does not move and can be easily operated from outside the front door.
