Description
本発明は、電力会社の電気所などに設置されている断路器の点検作業に使用するのに好適な断路器用操作ハンドル具および断路器点検作業方法に関する。 TECHNICAL FIELD The present invention relates to a disconnecting device operating handle and a disconnecting device inspection work method suitable for use in an inspection operation of a disconnecting device installed in an electric power company of an electric power company.
従来、電力会社では、電気所などに設置されている断路器（ＬＳ）を現地操作において開閉する際には、断路器の操作ロッド１（図３参照）の下端部の外周面に１８０°の間隔で垂設された第１および第２のアダプタ取付棒１ａ1，１ａ2に操作ハンドル用アダプタ（操作ハンドル用取付台）を取り付けて、図４（ａ）に示すような円柱状の棒状取手部１１１の先端面に垂設された高さｈおよび横幅ｗの矩形体形状（直方体形状または立方体形状）の嵌入部１１２を操作ハンドル用取付台の後面に形成された操作ハンドル取付穴に嵌入したのち、操作ハンドル１１０の棒状取手部１１１を操作ロッド１の周方向に沿って押して断路器の操作ロッド１を回転させている。
また、断路器の点検作業における開閉操作力の測定時には、断路器の操作ロッド１の第１および第２のアダプタ取付棒１ａ1，１ａ2にトルクハンドル用アダプタ（トルクハンドル用取付台）を取り付けて、図４（ｂ）に示すような四角柱形状の棒状取手部１１１の先端下面に垂設された縦幅Ｌｔおよび横幅Ｗｔの矩形体形状の嵌入部１２２をトルクハンドル用アダプタの上面に形成されたトルクハンドル取付穴に嵌入したのち、トルクハンドル１２０の棒状取手部１２１を操作ロッド１の周方向に沿って押して断路器の操作ロッド１を回転させている。
Conventionally, in an electric power company, when a disconnector (LS) installed at an electric power station or the like is opened and closed in a field operation, the outer peripheral surface of the lower end portion of the operation rod 1 (see FIG. 3) of the disconnector is 180 °. An operation handle adapter (operation handle mounting base) is attached to the first and second adapter mounting rods 1a 1 and 1a 2 which are vertically suspended, and a cylindrical rod handle as shown in FIG. Inserted into the operation handle mounting hole formed on the rear surface of the operation handle mounting base is a rectangular shape (rectangular shape or cube shape) fitting portion 112 having a height h and a lateral width w that is suspended from the front end surface of the portion 111. After that, the rod-shaped handle 111 of the operation handle 110 is pushed along the circumferential direction of the operation rod 1 to rotate the operation rod 1 of the disconnector.
At the time of measuring the opening / closing operation force in the inspection work of the disconnector, a torque handle adapter (torque handle mounting base) is attached to the first and second adapter mounting rods 1a 1 and 1a 2 of the operating rod 1 of the disconnector. 4 (b), a rectangular body-shaped fitting portion 122 having a vertical width Lt and a horizontal width Wt is formed on the upper surface of the torque handle adapter. After being inserted into the torque handle mounting hole, the rod-shaped handle 121 of the torque handle 120 is pushed along the circumferential direction of the operating rod 1 to rotate the operating rod 1 of the disconnector.
なお、下記の特許文献１には、扉が開いた状態では断路器の操作ができないようにするために、扉を閉めた状態で断路器の開閉を行うとともに、断路器が開状態で扉の開閉を可能にした閉鎖形盤において、操作ハンドルに嵌合して回転され、扉を閉めたとき、断路器の開閉を行う操作ロッドに嵌合して断路器の開閉を行うアダプタを扉に設置し、操作ハンドルと操作ロッドの嵌合形状を相違させた閉鎖形盤が開示されている。 In Patent Document 1 below, in order to prevent the disconnector from being operated when the door is open, the disconnector is opened and closed with the door closed, and the disconnector is opened and the door is open. In a closed-type panel that can be opened and closed, an adapter is installed on the door that fits into an operating rod that opens and closes the disconnector when the door is closed by being fitted to the operating handle and rotated. And the closed type board which made the fitting shape of an operation handle and an operation rod differ is disclosed.
しかしながら、操作ハンドル用アダプタおよび操作ハンドル１１０の嵌入部１１２の形状（高さｈおよび横幅ｗ）は断路器の機種ごとに異なっているため、多機種の断路器を設置している電気所では断路器の機種に応じた操作ハンドル用アダプタおよび操作ハンドル１１０を用意しておかなければならないという問題があった。
また、トルクハンドル用アダプタおよびトルクハンドル１２０は、少なくとも１本用意しておけば多機種の断路器について用いることができるが、断路器の操作ロッド１の径は機種によって異なるため、径の大きい操作ロッド１についてはトルクハンドル用アダプタを設置することができない場合があり、このような場合には、操作ロッド１の径が太い部分にトルクハンドル用アダプタを設置したり操作ロッド１の連結部の間隙に通した長いボルトを用いてトルクハンドル用アダプタを設置したりして開閉操作力の測定を行っているため、不安定な測定方法となっているという問題があった。
However, the shape (height h and lateral width w) of the operating handle adapter and the fitting portion 112 of the operating handle 110 differs depending on the type of disconnecting device. There has been a problem that an operation handle adapter and an operation handle 110 corresponding to the model of the vessel must be prepared.
Further, if at least one torque handle adapter and torque handle 120 are prepared, it can be used for many types of disconnectors. However, since the diameter of the operating rod 1 of the disconnector differs depending on the model, operation with a large diameter is possible. In some cases, the torque handle adapter may not be installed on the rod 1. In such a case, the torque handle adapter may be installed on the portion where the diameter of the operating rod 1 is large, or the gap between the connecting portions of the operating rod 1 may be removed. Since the torque handle adapter is installed using a long bolt that passes through the cable and the opening / closing operation force is measured, there is a problem that the measurement method is unstable.
