Description

本発明は、発変電所に設置する断路器に係り、特に断路器のブレードとフィンガーの投入ストッパーの位置関係を確認できる断路器の接触構造に関するものである。   The present invention relates to a disconnector installed in a power generation substation, and more particularly to a disconnector contact structure capable of confirming a positional relationship between a blade of a disconnector and a finger stopper.

発変電所に設置される断路器は、電気を開閉するスイッチの一種である。この断路器は、しゃ断器のように電流が流れている状態では開閉するものではなく、電流が流れていない状態で開閉するものである。通常、機器を点検するときは、先ずしゃ断器を開いて電流が流れない状態にしてから、両端又は片方の断路器を開路し、回路より切り離された状態で点検を行う。この断路器はスイッチ部分の構造により、代表的なものとして「水平一点切り」、「水平二点切り」、「垂直一点切り」などがある。   The disconnect switch installed at the power substation is a kind of switch that opens and closes electricity. This disconnector does not open and close in a state where current flows like a breaker, but opens and closes in a state where no current flows. Normally, when inspecting equipment, first open the circuit breaker so that no current flows, then open both ends or one of the circuit breakers, and perform the inspection with the circuit disconnected. Depending on the structure of the switch part, this disconnector typically includes “horizontal one-point cut”, “horizontal two-point cut”, “vertical one-point cut”, and the like.

従来の水平二点切り断路器1は、図1に示すように、ベース中央部にブレード支持部3を設け、このブレード支持部3にブレード4を水平方向に回動自在に取り付けたものである。このブレード4の両端部に、ブレード4の長手方向を中心軸として回動し得るように可動コンタクト5を取り付けた。この可動コンタクト5と電気的に接続するフィンガー6を断路器1のベース2にそれぞれ取り付けた。可動コンタクト5に隣接して取り付けたストッパー片7に、ノックピン8をブレード4の軸方向に対して円周方向へ突出させたものである。   As shown in FIG. 1, the conventional horizontal two-point disconnector 1 is provided with a blade support 3 at the center of the base, and the blade 4 is attached to the blade support 3 so as to be rotatable in the horizontal direction. . Movable contacts 5 were attached to both ends of the blade 4 so as to be rotatable about the longitudinal direction of the blade 4 as a central axis. Fingers 6 electrically connected to the movable contact 5 were attached to the base 2 of the disconnector 1. A knock pin 8 is protruded in a circumferential direction with respect to the axial direction of the blade 4 on a stopper piece 7 attached adjacent to the movable contact 5.

このように構成した断路器1について、フィンガー6に可動コンタクト5を閉路するときは、図5(a)に示すように、先ずブレード4を、ブレード支持部3を中心点として回動させて可動コンタクト5をフィンガー6に近づける。次に、図5(b)に示すように、投入ストッパー9の開口縁にノックピン8を当接させて、可動コンタクト5と共にストッパー片7を回動させる。最後に、図5(c)に示すように、ノックピン8が略水平になるように回動させて、このストッパー片7を投入ストッパー9の開口の突片10に掛け止める。   When the movable contact 5 is closed to the finger 6 in the disconnector 1 configured as described above, the blade 4 is first rotated around the blade support portion 3 as shown in FIG. The contact 5 is brought close to the finger 6. Next, as shown in FIG. 5B, the knock pin 8 is brought into contact with the opening edge of the insertion stopper 9, and the stopper piece 7 is rotated together with the movable contact 5. Finally, as shown in FIG. 5 (c), the knock pin 8 is rotated so as to be substantially horizontal, and the stopper piece 7 is hooked on the protruding piece 10 at the opening of the closing stopper 9.

このように、ブレードを回動させて断路器を開閉する技術が提案されている。例えば、特許文献1の特開平11−120870「水平二点切断路器」には、ベースの中央部に回転可能に支持された回転がいしと、ベースの両端部にそれぞれ載置された支持がいしとで、一相を構成している。回転がいしの上面には、両端部にコンタクトを有するブレードが、その長軸の回りに90°捻回可能に取り付けられるとともに、支持がいしの上面には、コンタクトを把持するフィンガーが取り付けられる。また、ブレードの両端部には、ノックピンが固着されるとともに、フィンガーの近傍には、投入ストッパーが固着されるものである。
特開平11−120870
In this way, a technique for opening and closing the disconnector by rotating the blade has been proposed. For example, in Japanese Patent Application Laid-Open No. 11-120870 “Horizontal Two-Point Cutting Path” in Patent Document 1, a rotating insulator supported rotatably at the center of the base, and a supporting insulator respectively mounted at both ends of the base. It constitutes one phase. A blade having contacts at both ends is attached to the upper surface of the rotating insulator so as to be able to twist 90 ° around its major axis, and a finger for gripping the contact is attached to the upper surface of the supporting insulator. In addition, a knock pin is fixed to both ends of the blade, and a closing stopper is fixed to the vicinity of the finger.
JP-A-11-120870

このように構成した断路器について定期設備パトロールをするときには、その断路器の接触状態の確認を行っている。特に、ストッパー片7と投入ストッパー9の位置関係について注意を払って確認する。しかし、従来の断路器の接触構造では、図6と図7に示すように、ストッパー片7と投入ストッパー9は同色であり、投入状態が不良、即ち、不完全投入であっても、投入ストッパー9の位置関係の判断が難しく見逃しやすいという問題を有していた。ここで不完全投入とは、フィンガーのバネ調整不足に起因するもの、捻回途中で停止すること、又は捻回状態に入る前に停止すること等を意味する。   When regular equipment patrol is performed on the disconnector configured as described above, the contact state of the disconnector is confirmed. In particular, pay attention to the positional relationship between the stopper piece 7 and the insertion stopper 9. However, in the contact structure of the conventional disconnector, as shown in FIGS. 6 and 7, the stopper piece 7 and the closing stopper 9 are the same color, and even if the closing state is poor, that is, the closing stopper is incomplete, 9 has a problem that it is difficult to judge the positional relationship and it is easy to overlook. Here, incomplete input means that the finger is caused by insufficient spring adjustment, stopping in the middle of twisting, or stopping before entering the twisted state.

また、連系変電所では、断路器の台数が多く、投入ストッパー9の位置関係の確認に時間を要するという問題を有していた。   In addition, the interconnected substation has a problem that the number of disconnecting devices is large, and it takes time to confirm the positional relationship of the closing stopper 9.

本発明は、上述した問題点を解決するために創案されたものである。すなわち本発明の目的は、上方の高い位置にある断路器の可動機構に簡単な処置を施すことで、断路器における投入ストッパーの位置関係を確実かつ容易に確認することができる断路器の接触構造を提供することにある。   The present invention has been developed to solve the above-described problems. That is, the object of the present invention is to provide a contact structure for a disconnector that can reliably and easily confirm the positional relationship of the closing stopper in the disconnector by applying a simple measure to the movable mechanism of the disconnector located at a high position above. Is to provide.

The protruding pieces (10) of the charging stopper (9) were colored in stripes.
A retroreflective material (13) was attached to the projecting piece (10) of the charging stopper (9).
A retroreflective plate was attached to the protruding piece (10) of the charging stopper (9).

例えば、水平二点切断路器は、断路器(1)のベース(2)中央部に設けたブレード支持部(3)に、水平方向に回動自在に取り付けたブレード(4)と、前記ブレード(4)の両端部に、該ブレード(4)の長手方向を中心軸として回動し得るように取り付けた可動コンタクト(5)と、前記断路器(1)のベース(2)に取り付けた、前記可動コンタクト(5)に電気的に接続する各フィンガー(6)と、前記可動コンタクト(5)に隣接して取り付けたストッパー片(7)に、該可動コンタクト(5)を回動させるために、前記ブレード(4)の軸方向に対して円周方向へ突出させたノックピン(8)と、前記フィンガー(6)に隣接して取り付けた、前記ストッパー片(7)を離接自在に掛け止める投入ストッパー(9)と、を備え、前記投入ストッパー(9)の開口縁に前記ノックピン(8)を当接させて、前記可動コンタクト(5)と共にストッパー片(7)を回動させて該投入ストッパー(9)に掛け止め状態を明確に表示できるように、該投入ストッパー(9)と前記ストッパー片(7)とを、視覚状態が異なる部材でそれぞれ構成した。   For example, the horizontal two-point cutting path device includes a blade (4) attached to a blade support portion (3) provided at a center portion of the base (2) of the disconnecting device (1) so as to be rotatable in the horizontal direction, and the blade A movable contact (5) attached to both ends of (4) so as to be rotatable about the longitudinal direction of the blade (4) and a base (2) of the disconnector (1), In order to rotate the movable contact (5) between each finger (6) electrically connected to the movable contact (5) and a stopper piece (7) attached adjacent to the movable contact (5) The knock pin (8) projecting in the circumferential direction with respect to the axial direction of the blade (4) and the stopper piece (7) attached adjacent to the finger (6) are detachably latched.

On the other hand, in the incomplete charging state, the stopper piece (7) is in front of the protruding piece (10) of the charging stopper (9), so that the coloring or the like cannot be confirmed. Therefore, since it is possible to easily confirm whether the blade (4) in the disconnector (1) is in the normal state or incomplete state, the regular equipment patrol can be executed quickly.

高い位置にあるブレード(4)についても、着色以外に蓄光塗料、ストライプ状の塗布、再帰反射材(13)又は再帰反射板等を用いることで、定期設備パトロール時の断路器(1)の状態を容易に確認することができる。   The state of the disconnector (1) at the time of regular equipment patrol by using a phosphorescent paint, striped coating, retroreflective material (13) or retroreflective plate, etc. in addition to coloring the blade (4) at a high position. Can be easily confirmed.

本発明の断路器の接触構造は、投入ストッパーとストッパー片とを視覚状態が異なる部材で構成したので、投入ストッパーの開口縁にノックピンを当接させ、可動コンタクトと共にストッパー片を回動させて投入ストッパーに掛け止めている状態を明確に表示できる。   In the disconnector contact structure of the present invention, the closing stopper and the stopper piece are composed of members having different visual states. Therefore, the knock pin is brought into contact with the opening edge of the closing stopper, and the stopper piece is rotated together with the movable contact to be turned on. The state of being hooked on the stopper can be clearly displayed.

以下、本発明の好ましい実施の形態を図面を参照して説明する。
図1は本発明の接触構造を備える断路器を示す平面図であり、(a)はブレードを閉じる状態、(b)はブレードが閉じた状態である。
本発明の接触構造を備える断路器1、例えば水平二点切断路器は、ベース2中央部に設けたブレード支持部3に、ブレード4を水平方向に回動自在に取り付け、このブレード4の両端部に、ブレード4の長手方向を回動中心軸として回動し得るように可動コンタクト5を取り付けたものである。また、断路器1のベース2に、可動コンタクト5に電気的に接続する各フィンガー6を取り付けている。
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1A and 1B are plan views showing a disconnector having a contact structure according to the present invention, in which FIG. 1A shows a state in which the blade is closed, and FIG. 1B shows a state in which the blade is closed.
A disconnector 1 having a contact structure of the present invention, for example, a horizontal two-point disconnector, is attached to a blade support 3 provided at the center of a base 2 so that the blade 4 can be rotated in the horizontal direction. A movable contact 5 is attached to the part so that the blade 4 can be rotated about the longitudinal direction of the blade 4 as a rotation center axis. Each finger 6 that is electrically connected to the movable contact 5 is attached to the base 2 of the disconnector 1.

図2は実施例1の着色塗料を塗布した接触構造の拡大正面図である。
実施例1の接触構造は、可動コンタクト5に隣接して取り付けたストッパー片7に、この可動コンタクト5を回動させるために、ブレード4の軸方向に対して円周方向へ突出させたノックピン8を取り付けたものである。一方、ストッパー片7は、フィンガー6に隣接して取り付けた投入ストッパー9に離接自在に掛け止める。投入ストッパー9は、横向き略コ字形状になり、上側部材に下方へ向けてストッパー片7を掛け止める突片10を設けたものである。
FIG. 2 is an enlarged front view of the contact structure to which the colored paint of Example 1 is applied.
The contact structure of the first embodiment has a knock pin 8 that is protruded in the circumferential direction with respect to the axial direction of the blade 4 in order to rotate the movable contact 5 on a stopper piece 7 attached adjacent to the movable contact 5. Is attached. On the other hand, the stopper piece 7 is detachably hooked on a closing stopper 9 attached adjacent to the finger 6. The throwing stopper 9 has a substantially U-shape in the horizontal direction, and is provided with a protruding piece 10 for hooking the stopper piece 7 downward on the upper member.

本発明では、この突片10にストッパー片7とは異なる色彩を施した。例えば、投入ストッパー9の突片10を黄色に着色した(図2では斜線部分で示した黄色着色部11)。この黄色の着色に代えて、蓄光塗料を塗布したものでもよい。本発明では、突片10に投入ストッパー9と異なる色彩を施したものであれば、これら以外の色彩又は塗料を用いることができる。   In the present invention, the protruding piece 10 is colored differently from the stopper piece 7. For example, the protruding piece 10 of the charging stopper 9 is colored yellow (yellow colored portion 11 shown by a hatched portion in FIG. 2). Instead of this yellow coloring, a phosphorescent paint may be applied. In the present invention, any color or paint other than these can be used as long as the projecting piece 10 has a color different from that of the insertion stopper 9.

このように構成した接触構造では、断路器1を閉路にするときに、投入ストッパー9の開口縁にノックピン8を当接させ、可動コンタクト5と共にストッパー片7を回動させながら投入ストッパー9に掛け止める。この投入ストッパー9にストッパー片7が掛け止められている状態を、投入ストッパー9の突片10を黄色に着色したので、投入状態を容易かつ確実に確認することができる。即ち、ブレード4が完全投入状態のときは、ブレード4が投入ストッパー9の突片10の後側になるのでその黄色の着色等を確認できる。一方、不完全な投入状態のときは、ブレード4が投入ストッパー9の突片10の手前となるためその着色等を確認できない。そこで、断路器1のブレード4の投入状態が正常投入か、不完全投入かを容易に確認できる。   In the contact structure configured as described above, when the disconnector 1 is closed, the knock pin 8 is brought into contact with the opening edge of the closing stopper 9 and the stopper piece 7 is rotated together with the movable contact 5 to be hung on the closing stopper 9. stop. Since the protruding piece 10 of the charging stopper 9 is colored yellow when the stopper piece 7 is hooked on the charging stopper 9, the charging state can be easily and reliably confirmed. That is, when the blade 4 is in the fully charged state, the blade 4 is located behind the protruding piece 10 of the loading stopper 9, so that the yellow coloration can be confirmed. On the other hand, in the incomplete charging state, the blade 4 is in front of the protruding piece 10 of the charging stopper 9, so that the coloring or the like cannot be confirmed. Therefore, it can be easily confirmed whether the blade 4 of the disconnector 1 is in a normal state or an incomplete state.

図3は実施例2のストライプ状に着色した接触構造の拡大正面図である。
実施例2の接触構造は、投入ストッパー9の突片10をストライプ状に着色したものである。実施例2では突片10を単に着色するだけでなく、ストライプ状模様部12を設けることで、断路器1のブレード4の投入状態が正常投入か、不完全投入かをより容易に確認できる。
FIG. 3 is an enlarged front view of the contact structure colored in a stripe shape according to the second embodiment.
In the contact structure of Example 2, the protruding piece 10 of the charging stopper 9 is colored in a stripe shape. In the second embodiment, not only the projecting piece 10 is simply colored, but also by providing the striped pattern portion 12, it can be more easily confirmed whether the blade 4 of the disconnector 1 is in the normal input state or incompletely input.

図4は実施例3の再帰反射材を貼り付けた接触構造の拡大正面図である。
実施例3の接触構造は、投入ストッパー9の突片10にシール状の再帰反射材13を貼り付けたものである。このように再帰反射材13を貼り付けるだけで瞬時に作業を完了させることができる。例えば、夕闇のように暗いときは、この再帰反射材13に光を当てるだけで容易に判断することができる。このシール状の再帰反射材13に代えて再帰反射板を取り付けることも可能である。この再帰反射材13又は再帰反射材を施すことで、高い位置にあるブレード4についても、定期設備パトロール時の断路器1の状態を容易、確実に、しかも短時間で確認でき、異常の早期発見が可能となる。
FIG. 4 is an enlarged front view of a contact structure to which the retroreflective material of Example 3 is attached.
In the contact structure of Example 3, a seal-like retroreflective material 13 is attached to the protruding piece 10 of the insertion stopper 9. In this way, the work can be completed instantaneously simply by pasting the retroreflective member 13. For example, when it is dark like dusk, it can be easily determined by simply applying light to the retroreflective member 13. It is also possible to attach a retroreflective plate in place of the seal-like retroreflective member 13. By applying the retroreflective material 13 or the retroreflective material, the state of the disconnector 1 at the time of regular equipment patrol can be confirmed easily, reliably and in a short time even for the blade 4 at a high position, and early detection of abnormalities Is possible.

なお、本発明の断路器の接触構造は、投入ストッパー9とストッパー片7とを視覚状態が異なる部材でそれぞれを構成することで、断路器1における投入ストッパー9の位置関係を確実かつ容易に確認することができれば、上述した発明の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。   In the disconnector contact structure according to the present invention, the closing stopper 9 and the stopper piece 7 are formed of members having different visual states, so that the positional relationship of the closing stopper 9 in the disconnector 1 can be confirmed reliably and easily. If it can be done, it is not limited to the embodiment of the invention described above, and various changes can be made without departing from the gist of the invention.

本発明の断路器の接触構造は、主に断路器の投入ストッパーとストッパー片との位置関係の確認に利用できるが、断路器以外に種々の機器類の開閉状態の確認に利用することができる。   The disconnector contact structure of the present invention can be used mainly for confirming the positional relationship between the stopper and the stopper piece of the disconnector, but can be used for confirming the open / closed state of various devices other than the disconnector. .
