Description

本発明は、高圧配電線路の変圧器の一次側保護用として用いられる円筒形高圧カットアウトに係り、詳しくは、管状ヒューズを挿入するための装填口に着脱自在に設けられる密封蓋の支持構造等に関する。   The present invention relates to a cylindrical high voltage cutout used for protecting a primary side of a transformer of a high voltage distribution line, and more specifically, a support structure for a sealing lid that is detachably provided at a loading port for inserting a tubular fuse, and the like. About.

円筒形高圧カットアウトは、例えば、図６に示すように、カットアウト本体１の下部に一体化された下部スカート２に、管状ヒューズ３を装填するための円形状の装填口４を設けており、その装填口４には、塩水や異物の侵入を防止するための円板状に形成された密封蓋５が着脱自在に取り付けられる（例えば、特許文献１参照）。その密封蓋５は、装填口４に設けられている係止爪６によって係脱自在に係止され、かつ、紐体７を介してカットアウト本体１に連結され、その背面側（外側）には、ＣＦ操作棒の先端に設けられている間接活線先端工具を係入させるための係止穴５ｈが形成されている。なお、カットアウト本体１は碍子により形成され、下部スカート２は硬質樹脂材の一体成形により形成される。   For example, as shown in FIG. 6, the cylindrical high-pressure cutout is provided with a circular loading port 4 for loading a tubular fuse 3 in a lower skirt 2 integrated with a lower portion of the cutout body 1. The loading port 4 is detachably attached with a sealing lid 5 formed in a disk shape for preventing the intrusion of salt water or foreign matter (see, for example, Patent Document 1). The sealing lid 5 is detachably locked by a locking claw 6 provided in the loading port 4 and is connected to the cutout body 1 via a string body 7, on the back side (outside). Is formed with a locking hole 5h for engaging an indirect hot wire tip tool provided at the tip of the CF operation rod. The cutout main body 1 is formed of an insulator, and the lower skirt 2 is formed by integral molding of a hard resin material.

このような構成により、電流遮断時における管状ヒューズ３の放出圧力（アーク及びガスを含む）が密封蓋５に作用すると、密封蓋５は装填口４から離脱するが、その際に、紐体７によってカットアウト本体１に吊り下げられた状態に保持されるため、その密封蓋５を再度の使用に供することができる。即ち、新しい管状ヒューズを装填するには、ＣＦ操作棒によって管状ヒューズをカットアウト本体１内に挿入した後、吊り下げ状態の密封蓋５をＣＦ操作棒によって装填口４に押込み係止爪６に係止させるようにしていた。   With such a configuration, when the discharge pressure (including arc and gas) of the tubular fuse 3 at the time of current interruption acts on the sealing lid 5, the sealing lid 5 is detached from the loading port 4. Therefore, the sealing lid 5 can be used again. That is, in order to load a new tubular fuse, the tubular fuse is inserted into the cutout body 1 with the CF operation rod, and then the suspended sealing lid 5 is pushed into the loading port 4 with the CF operation rod to the locking claw 6. I was trying to lock it.

特開平９−２８２９９８号公報JP-A-9-282998

しかし、上述のように、密封蓋５が紐体７を介してカットアウト本体１に連結されている場合には、吊り下げ状態になっている密封蓋５をＣＦ操作棒によって装填口４に係止させるのは容易ではなかった。即ち、通常、円筒形高圧カットアウトは高所に配設されているため、風が強いときには吊り下げ状態の密封蓋５は激しく揺らぐためＣＦ操作棒によって捉えるのが容易ではなかった。また、密封蓋５の背面側（外側）に設けられている係止穴５ｈの内壁はストレートに形成されているため、折角ＣＦ操作棒で密封蓋５を捉えてもその係止穴５ｈに円筒状の間接活線先端工具を係入させるのは容易ではなかった。さらに、密封蓋５が激しく揺らぐときには、紐体７が電柱の腕金や高圧配電線に引っ掛かり大きなトラブルの原因になることもあり、その紐体７が切れて密封蓋５が紛失してしまうこともあった。   However, as described above, when the sealing lid 5 is connected to the cutout body 1 via the string body 7, the suspended sealing lid 5 is engaged with the loading port 4 by the CF operation rod. It was not easy to stop. That is, since the cylindrical high-pressure cutout is usually arranged at a high place, the suspended sealing lid 5 sways violently when the wind is strong, so that it was not easy to catch with the CF operation rod. Further, since the inner wall of the locking hole 5h provided on the back side (outside) of the sealing lid 5 is formed straight, even if the sealing lid 5 is caught by the bent CF operation rod, the locking hole 5h is cylindrical. It is not easy to engage the indirect hot wire tip tool. Furthermore, when the sealing lid 5 shakes violently, the string body 7 may be caught on the armature of the utility pole or the high-voltage distribution line, causing a serious trouble, and the string body 7 is cut and the sealing lid 5 is lost. There was also.

本発明は、このような実情に鑑みてなされ、操作棒により密封蓋を容易に開閉できるようにした円筒形高圧カットアウトを提供することを目的とする。   The present invention has been made in view of such a situation, and an object of the present invention is to provide a cylindrical high-pressure cutout that can be easily opened and closed with an operating rod.

（１）本発明の円筒形高圧カットアウトは、カットアウト本体１の下部に一体化された下部スカート２に管状ヒューズ３を挿入するために形成された装填口４を密封蓋５によって開閉自在に密封するようにした円筒形高圧カットアウト２０であって、
前記密封蓋５の一端側は、前記下部スカート２の外側に設けた支持部材２ａに回動自在に枢支される一方、前記密封蓋５の他端側は、前記下部スカート２の内側に設けた係止部材６に係脱自在に係止されることを特徴とする。 (1) The cylindrical high-pressure cutout according to the present invention can be opened and closed by a sealing lid 5 at a loading port 4 formed for inserting a tubular fuse 3 into a lower skirt 2 integrated at the lower part of the cutout body 1 A cylindrical high pressure cutout 20 adapted to be sealed,
One end side of the sealing lid 5 is pivotally supported by a support member 2 a provided outside the lower skirt 2, while the other end side of the sealing lid 5 is provided inside the lower skirt 2. It is characterized in that it is detachably locked to the locking member 6.

このような構成によれば、電流遮断時における管状ヒューズ３の放出圧力（アーク及びガスを含む）が密封蓋５に作用すると、密封蓋５の他端側は、下部スカート２の内側に設けた係止部材６から離脱して密封蓋５が開放され、溶出した管状ヒューズ３が外部に放出される。   According to such a configuration, when the discharge pressure (including arc and gas) of the tubular fuse 3 at the time of current interruption acts on the sealing lid 5, the other end side of the sealing lid 5 is provided inside the lower skirt 2. The sealing lid 5 is released from the locking member 6 and the eluted tubular fuse 3 is discharged to the outside.

その密封蓋５の一端側は、下部スカート２に設けた支持部材２ａに回動自在に枢支されているため、密封蓋５は下部スカート２に接続された状態で開放される。従って、新しい管状ヒューズをカットアウト本体１に挿入する際には、操作棒で密封蓋５を容易に捉えることができ、その開閉作業が容易となる。また、密封蓋５が紛失することもない。   Since one end side of the sealing lid 5 is pivotally supported by a support member 2 a provided on the lower skirt 2, the sealing lid 5 is opened while being connected to the lower skirt 2. Therefore, when a new tubular fuse is inserted into the cutout body 1, the sealing lid 5 can be easily caught by the operating rod, and the opening / closing operation is facilitated. Further, the sealing lid 5 is not lost.

（２）前記密封蓋５の他端外側には、操作棒の先端工具９，１０を係止させるための係止部８を設けてあってもよい。このようにすれば、密封蓋５を開閉する際に、操作棒の先端工具９又は１０を係止部８に係止させることで、その開閉作業が容易となる。 (2) On the outer side of the other end of the sealing lid 5, a locking portion 8 for locking the tip tools 9, 10 of the operating rod may be provided. In this way, when the sealing lid 5 is opened and closed, the opening / closing operation is facilitated by locking the tip tool 9 or 10 of the operating rod to the locking portion 8.

（３）前記係止部８は、ＣＦ操作棒の円筒状の先端工具９を被嵌可能な突起状に形成され、かつ、ＰＣ操作棒の先尖り状の先端工具１０を係入可能な係止孔８ａを有していてもよい。このようにすれば、ＣＦ操作棒又はＰＣ操作棒の何れを用いても、その先端工具９又は１０を係止部８に係止させて密封蓋５の開閉作業を行うことができ利便性が向上する。 (3) The locking portion 8 is formed in a protrusion shape that can be fitted with the cylindrical tip tool 9 of the CF operation rod, and can be engaged with the pointed tip tool 10 of the PC operation rod. You may have the stop hole 8a. In this way, regardless of whether a CF operation rod or a PC operation rod is used, the tip tool 9 or 10 can be engaged with the engagement portion 8 so that the sealing lid 5 can be opened and closed. improves.

（４）前記密封蓋５の内面には、衝撃を吸収することができる弾性材１１が付設されていてもよい。このようにすれば、電流遮断時に密封蓋５に作用する管状ヒューズ３の放出圧力（アーク及びガスを含む）による衝撃を弾性材１１によって吸収緩和することができ、密封蓋５及びその支持構造の長寿命化が可能となる。 (4) An elastic material 11 capable of absorbing an impact may be attached to the inner surface of the sealing lid 5. In this way, the elastic material 11 can absorb and mitigate the impact caused by the discharge pressure (including arc and gas) of the tubular fuse 3 acting on the sealing lid 5 when the current is interrupted, and the sealing lid 5 and its supporting structure Long service life is possible.

（５）前記密封蓋５の他端側を、下方に向けて傾斜させてもよい。このようにすれば、電流遮断時に密封蓋５に作用する管状ヒューズ３の放出圧力（アーク及びガスを含む）が密封蓋５の他端側に向かうため、一端側に設けてある蓋支持部に作用する衝撃を緩和することができる。 (5) The other end side of the sealing lid 5 may be inclined downward. In this way, since the discharge pressure (including arc and gas) of the tubular fuse 3 acting on the sealing lid 5 when the current is interrupted is directed to the other end side of the sealing lid 5, the lid support portion provided on one end side The acting impact can be reduced.

（６）前記密封蓋５の内面には、螢光塗料が塗布されていてもよい。このようにすれば、電流遮断時における管状ヒューズ３の放出圧力（アーク及びガスを含む）が密封蓋５に作用して密封蓋５が開放されると、その内面に塗布されている螢光塗料が外部に露出するため、トラブルの発生を外部から容易に検知することができる。 (6) A fluorescent paint may be applied to the inner surface of the sealing lid 5. In this way, when the discharge pressure (including arc and gas) of the tubular fuse 3 at the time of current interruption acts on the sealing lid 5 and the sealing lid 5 is opened, the fluorescent paint applied to the inner surface thereof Is exposed to the outside, it is possible to easily detect the occurrence of trouble from the outside.

本発明の円筒形高圧カットアウトは、カットアウト本体に一体化された下部スカートの装填口に密封蓋を開閉自在に設けたので、電流遮断時における管状ヒューズの放出圧力（アーク及びガスを含む）が密封蓋に作用すると、密封蓋の他端側が下部スカートの内側に設けた係止部材から離脱して密封蓋が開放され、溶出した管状ヒューズが外部に放出される。その密封蓋は、その一端側をカットアウト本体と一体の下部スカートに接続された状態で開放されるため、新しい管状ヒューズをカットアウト本体に挿入する際には、操作棒で密封蓋を容易に捉えることができ、その閉止作業を容易に行うことができる。   Since the cylindrical high-pressure cutout according to the present invention is provided with a sealing lid at the loading port of the lower skirt integrated with the cutout body so as to be freely opened and closed, the discharge pressure of the tubular fuse at the time of current interruption (including arc and gas) When this acts on the sealing lid, the other end side of the sealing lid is detached from the locking member provided inside the lower skirt, the sealing lid is opened, and the eluted tubular fuse is discharged to the outside. The sealing lid is opened with its one end connected to the lower skirt integrated with the cutout body, so when inserting a new tubular fuse into the cutout body, the sealing lid can be easily moved with the operating rod. It can be grasped and the closing operation can be easily performed.

以下に、本発明の最良の実施の形態に係る円筒形高圧カットアウトについて図面を参照しつつ詳細に説明する。
図１は円筒形高圧カットアウト２０の外形図、図２は図１のＢ−Ｂ線矢視断面図である。これらの図にて、符号１は円筒形のカットアウト本体、２は下部スカートで、カットアウト本体１の下部に一体化されている。３は管状ヒューズで、下部スカート２に形成された装填口４からカットアウト本体１内に装填される。５は、円板状の密封蓋で、下部スカート２の装填口４を開閉自在に密封する。 Hereinafter, a cylindrical high-pressure cutout according to the best mode of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an external view of a cylindrical high-pressure cutout 20, and FIG. 2 is a cross-sectional view taken along line BB in FIG. In these drawings, reference numeral 1 is a cylindrical cutout body, 2 is a lower skirt, and is integrated with the lower part of the cutout body 1. Reference numeral 3 denotes a tubular fuse, which is loaded into the cutout body 1 from a loading port 4 formed in the lower skirt 2. A disk-shaped sealing lid 5 seals the loading port 4 of the lower skirt 2 so as to be freely opened and closed.

上述の密封蓋５の一端側には、略Ｌ字状に折曲された支持アーム５ａが形成され、その支持アーム５ａの二股状に形成された先端部に穿設されたボルト孔（図示省略）を、下部スカート２の外側に突設した支持部材２ａに穿設されたボルト孔（図示省略）に対応させ、これらのボルト孔にボルトｂを挿通させてナットｎで締結することにより、密封蓋５が下部スカート２に回動自在に枢支される。一方、前記密封蓋５の他端側端部は、下部スカート２の内側に設けた係止部材６に係脱自在に係止される。なお、係止爪６は、ばね板材からなり、拡大図に示すように、下部スカート２に形成された凹部２ｂ内に嵌め込まれている。   A support arm 5a bent in a substantially L shape is formed on one end side of the sealing lid 5 described above, and a bolt hole (not shown) drilled in a bifurcated tip of the support arm 5a. ) Corresponding to bolt holes (not shown) drilled in the support member 2a projecting outside the lower skirt 2, and bolts b are inserted into these bolt holes and fastened with nuts n to seal The lid 5 is pivotally supported by the lower skirt 2. On the other hand, the other end side end of the sealing lid 5 is detachably locked to a locking member 6 provided inside the lower skirt 2. The latching claw 6 is made of a spring plate material and is fitted into a recess 2b formed in the lower skirt 2 as shown in the enlarged view.

この密封蓋５の他端外側には係止部８を設けてあり、この係止部８は、ＣＦ操作棒の円筒状に形成された間接活線先端工具９を被嵌可能な突起状に形成され、かつ、ＰＣ操作棒の先尖り状に形成された間接活線先端工具１０を係入可能な係止孔８ａを有している。従って、ＣＦ操作棒又はＰＣ操作棒の何れを用いても、密封蓋５を開閉することができる。即ち、ＣＦ操作棒を用いる場合には、その間接活線先端工具９を係止部８に押込み被嵌させて密封蓋５の開方向又は閉方向に操作することで密封蓋５を開閉することができる。また、ＰＣ操作棒を用いる場合には、その間接活線先端工具１０を係止孔８ａに係入させて密封蓋５の開方向又は閉方向に操作することで密封蓋５を開閉することができる。なお、図２には、開状態の密封蓋５を二点鎖線で示す。   A locking portion 8 is provided on the outer side of the other end of the sealing lid 5, and the locking portion 8 has a protrusion shape into which the indirect live wire tip tool 9 formed in a cylindrical shape of a CF operation rod can be fitted. It has a locking hole 8a that is formed and into which the indirect hot wire tip tool 10 formed in the shape of a tip of a PC operation rod can be inserted. Therefore, the sealing lid 5 can be opened and closed using either the CF operation bar or the PC operation bar. That is, when the CF operation rod is used, the indirect live wire tip tool 9 is pushed and fitted into the engaging portion 8 and is operated in the opening direction or the closing direction of the sealing lid 5 to open and close the sealing lid 5. Can do. In the case of using a PC operation rod, the indirect hot wire tip tool 10 is engaged with the locking hole 8a and operated in the opening direction or the closing direction of the sealing lid 5 to open and close the sealing lid 5. it can. In FIG. 2, the sealing lid 5 in the open state is indicated by a two-dot chain line.

このような構成の円筒形高圧カットアウト２０によれば、電流遮断時における管状ヒューズ３の放出圧力（アーク及びガスを含む）が密封蓋５に作用すると、密封蓋５の他端側端部が下部スカート２の内側に設けた係止部材６から離脱し、密封蓋５が開放され、溶出した管状ヒューズ３が外部に放出される。密封蓋５の一端側が下部スカート２に枢支されているため、新しい管状ヒューズをカットアウト本体１に挿入する際には、ＣＦ操作棒又はＰＣ操作棒で密封蓋５を容易に捉えることができ、その開閉作業が容易となる。また、密封蓋５が紛失することがない。そして、本実施の形態では、密封蓋５を枢支するボルトｂを密封蓋５の中心から外方に離間した位置に配設しているため、電流遮断時に管状ヒューズ３の大きな放出圧力が密封蓋５に作用しても、ボルトｂ及びその支持構造に対する衝撃的な負荷を軽減緩和することができ、良好な耐久性を確保することができる。   According to the cylindrical high voltage cutout 20 having such a configuration, when the discharge pressure (including arc and gas) of the tubular fuse 3 at the time of current interruption acts on the sealing lid 5, the end on the other end side of the sealing lid 5 is It is detached from the locking member 6 provided inside the lower skirt 2, the sealing lid 5 is opened, and the eluted tubular fuse 3 is discharged to the outside. Since one end side of the sealing lid 5 is pivotally supported by the lower skirt 2, when inserting a new tubular fuse into the cutout body 1, the sealing lid 5 can be easily caught with a CF operation rod or a PC operation rod. The opening / closing operation becomes easy. Further, the sealing lid 5 is not lost. In this embodiment, since the bolt b that pivotally supports the sealing lid 5 is disposed at a position spaced outward from the center of the sealing lid 5, a large discharge pressure of the tubular fuse 3 is sealed when the current is interrupted. Even if it acts on the lid 5, the shock load on the bolt b and its supporting structure can be reduced and relaxed, and good durability can be ensured.

図３は異なる実施の形態を示し、この例では、密封蓋５の内面に、衝撃を吸収することができる弾性材１１を付設している。この弾性材１１は、例えば、耐熱性の合成ゴムからなる本体１１ａの上面に遮熱用の金属板１１ｂを貼着したものが好ましい。このような構成にすることで、電流遮断時に密封蓋５に作用する管状ヒューズ３の放出圧力による衝撃を弾性材１１によって吸収緩和することができ、密封蓋５及びその支持構造の長寿命化が可能となる。なお、前実施の形態（及び従来例）と同一部材又は同等部材については同一符号を付し、その説明を省略する。この点については、その他の実施の形態においても同様である。   FIG. 3 shows a different embodiment. In this example, an elastic material 11 capable of absorbing an impact is attached to the inner surface of the sealing lid 5. The elastic material 11 is preferably made of, for example, a heat shield metal plate 11b attached to the upper surface of a main body 11a made of heat-resistant synthetic rubber. By adopting such a configuration, the impact due to the discharge pressure of the tubular fuse 3 acting on the sealing lid 5 when current is interrupted can be absorbed and relaxed by the elastic material 11, and the life of the sealing lid 5 and its supporting structure can be extended. It becomes possible. In addition, the same code | symbol is attached | subjected about the same member as previous embodiment (and conventional example), or an equivalent member, and the description is abbreviate | omitted. This is the same in other embodiments.

図４は別の実施の形態を示し、この例では、密封蓋５の他端側を下方に向けて傾斜させている。このようにすれば、電流遮断時に密封蓋５に作用する管状ヒューズ３の放出圧力による衝撃的な負荷が密封蓋５の他端側に向かうため、一端側に設けてあるボルトｂ及びその支持構造に対する衝撃的な負荷を軽減緩和することができ、良好な耐久性を確保することができる。   FIG. 4 shows another embodiment. In this example, the other end of the sealing lid 5 is inclined downward. In this way, since an impact load due to the discharge pressure of the tubular fuse 3 acting on the sealing lid 5 when the current is interrupted is directed to the other end side of the sealing lid 5, the bolt b provided on one end side and the support structure thereof It is possible to reduce and alleviate the shocking load on the surface, and to ensure good durability.

図５はさらに別の実施の形態を示し、この例では、密封蓋５の外面に、ＣＦ操作棒の間接活線先端工具１０を係入させるための係止穴５ｂを形成すると共に、支持アーム５ａの枢支点側に外向きに突出させた蓋解放用の操作片５ｃを形成している。その係止穴５ｂは、従来のものよりも浅く形成され、かつ、間接活線先端工具１０を係止させやすくするために、下向き（外向き）の喇叭状に形成されている。   FIG. 5 shows still another embodiment. In this example, a locking hole 5b for engaging the indirect hot wire tip tool 10 of the CF operation rod is formed on the outer surface of the sealing lid 5, and a support arm is formed. An operation piece 5c for releasing the lid is formed on the pivot point side of 5a so as to protrude outward. The locking hole 5b is formed shallower than the conventional one, and is formed in a downward (outward) hook shape so that the indirect live wire tip tool 10 can be easily locked.

このような構成によれば、密封蓋５を開く際には、操作片５ｃに下方から間接活線先端工具１０を押し当てて押し上げればよく、閉じる際には、係止穴５ｂに間接活線先端工具１０を押し込み押し上げればよい。その係止穴５ｂが喇叭状に形成されており、かつ、密封蓋５が下部スカート２に接続された状態で開放されているため、間接活線先端工具１０を係止穴５ｂに押し込むのは容易であり、前各実施の形態と同様に、密封蓋５を作業性よく開閉することができる。   According to such a configuration, when the sealing lid 5 is opened, the indirect hot wire tip tool 10 may be pressed from the lower side against the operation piece 5c and pushed up. The wire tip tool 10 may be pushed in and pushed up. Since the locking hole 5b is formed in a bowl shape and the sealing lid 5 is opened in a state of being connected to the lower skirt 2, the indirect hot wire tip tool 10 is pushed into the locking hole 5b. It is easy, and the sealing lid 5 can be opened and closed with good workability as in the previous embodiments.

また、図示は省略するが、前記各実施の形態に示す円筒形高圧カットアウト２０において、密封蓋５の内面に螢光塗料を塗布するのが好ましい。このようにすれば、電流遮断時における管状ヒューズ３の放出圧力が密封蓋５に作用して密封蓋５が開放されると、その内面に塗布されている螢光塗料が外部に露出するため、トラブルの発生を外部から容易に検知することができる。   Although not shown, it is preferable to apply a fluorescent paint to the inner surface of the sealing lid 5 in the cylindrical high-pressure cutout 20 shown in the above embodiments. In this way, when the discharge pressure of the tubular fuse 3 at the time of current interruption acts on the sealing lid 5 and the sealing lid 5 is opened, the fluorescent paint applied on the inner surface is exposed to the outside. The occurrence of trouble can be easily detected from the outside.

なお、本発明は、実施の形態に限定されることなく、発明の要旨を逸脱しない限りにおいて、適宜、必要に応じて、設計変更や改良等を行うのは自由であり、また、各実施の形態間での構成の組み合わせも自由である。例えば、実施の形態では、密封蓋５を円板状に形成しているが、楕円状に形成してもよい。また、密封蓋５を平板状に形成しているが、略中央部あたりを凹ませて深底状に形成して電流遮断時における管状ヒューズ３の放出圧力の影響を緩和するようにしてもよい。   It should be noted that the present invention is not limited to the embodiments, and it is free to make design changes and improvements as necessary, as long as it does not depart from the gist of the invention. Combinations of configurations between forms are also free. For example, in the embodiment, the sealing lid 5 is formed in a disc shape, but may be formed in an elliptical shape. Further, although the sealing lid 5 is formed in a flat plate shape, the influence of the discharge pressure of the tubular fuse 3 at the time of current interruption may be alleviated by forming a deep bottom shape by denting the substantially central portion. .
