(57) [Summary] [Purpose] In tap switching work such as transformers, taps can be switched without using tools.
The nut and connecting conductor are designed so that they will not fall into the tank. [Structure] The connection conductor 2a is fixed by an ordinary butterfly nut 4 at one end on the center tap side, and by a thin special butterfly nut 3 at the other end on the tap side arranged in an arc. On the other end side of the connection conductor 2a, an elongated hole 9 through which the special butterfly nut 3 is removed is provided.

【従来の技術】[Prior art]

図2は、従来のタップ切換えに使用するタップ切換装置で、絶縁物のタツプ切 換台1に対し、垂直に貫通した穴に、ねじ部材5を挿入し、六角ナット6aで仮 締めをし、そのねじ部材5に接続導体2bを入れ、六角ナット6cで締め付けて 、6a、6cの接触圧力により電気的接続を行う。 また、タップ切換台1の下面には、圧着端子7に、タップ線8を接続し、六角 ナット6bで、タップ切換台1に締め付けている。 FIG. 2 shows a conventional tap switching device used for tap switching, in which a screw member 5 is inserted into a hole vertically penetrating the tap switching base 1 of an insulator and temporarily tightened with a hexagon nut 6a. The connection conductor 2b is put into the screw member 5 and tightened with a hexagon nut 6c to make an electrical connection by the contact pressure of 6a and 6c. Further, a tap wire 8 is connected to the crimp terminal 7 on the lower surface of the tap switching base 1, and the tap switching base 1 is tightened with a hexagon nut 6b.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、前記の従来の方法では、タップ切換作業に工具類を使用しなけ ればならないとともに、タップ切換え時に作業者が、六角ナット6cや、接続導 体2b、および工具などの異物をタンクの中(油中)に落としてしまう欠点があ った。 そこで、本考案は、工具類を使用せず、タップの切換えができ、さらに工具, ナット,接続導体が、タンクの中に脱落しないようにしたものである。 However, in the above-mentioned conventional method, tools must be used for tap switching work, and at the time of tap switching, the operator must remove foreign matters such as the hexagon nut 6c, the connecting conductor 2b, and tools in the tank. It had the drawback of dropping into (in oil). Therefore, the present invention allows taps to be switched without using tools, and prevents the tools, nuts, and connecting conductors from falling into the tank.

【課題を解決するための手段】[Means for Solving the Problems]

本考案では、絶縁性のタップ切換台に、中心タップと、この中心タップを中心 とする円弧上に配列したタップとを接続する接続導体を、上記中心タップ側の一 端側は普通のちょうナットにより、上記円弧上に配列したタップ側の他端側は、 薄形の特殊ちょうナットにより固定するとともに、この接続導体の上記他端側に は、上記特殊ちょうナットが抜ける長穴を形成したタップ切換装置。 In the present invention, a connecting conductor for connecting a center tap and taps arranged in an arc centered on the center tap is attached to an insulating tap switching base, and one end side of the center tap side is an ordinary butterfly nut. The other end of the tap side arranged on the above arc is fixed with a thin special butterfly nut, and the tap with the elongated hole through which the special butterfly nut comes out is formed on the other end of this connecting conductor. Switching device.

【作用】[Action]

本考案により、タップを切換える際には、両側のちょうナットを接続導体を移 動するのに必要な分だけ緩めることにより、タップを切換えられるので、両ちょ うナット、および接続導体を脱離せず、タップ切換え作業が容易に、かつ安全に できる。 According to the present invention, when the taps are switched, the taps can be switched by loosening the hinge nuts on both sides as much as necessary to move the connection conductors, so that both the nuts and the connection conductors are not detached. The tap switching work can be done easily and safely.

【実施例】【Example】

図1は、本考案のタップ切換装置の実施例で、タップ切換台1に、ねじ部材5 を入れ、六角ナット6aで仮締めをし、そのねじ部材5に接続導体2aの長穴9 を、薄形の特殊ちょうナット3側において入れ、ちょうナット3,4を締め付け て、電気的接続を行う。この時、接続導体2aに特殊ちょうナット3が、抜ける 長穴9を空けておくことで、ちょうナット4と、特殊ちょうナット3を接続導体 2aを動かすのに必要な分だけ緩め、特殊ちょうナット3側だけ接続導体2aを 上方に外し、ちょうナット4を中心に接続導体2aを次のタップへ移動し、ちょ うナット3,4を締め付ける。 FIG. 1 shows an embodiment of the tap changer of the present invention, in which the screw member 5 is put in the tap changer 1 and temporarily tightened with a hexagon nut 6a, and the elongated hole 9 of the connection conductor 2a is attached to the screw member 5. Insert on the thin special hinge nut 3 side and tighten the butterfly nuts 3 and 4 for electrical connection. At this time, the special butterfly nut 3 is formed in the connecting conductor 2a by leaving the elongated hole 9 through which the special nut 3 is loosened by the amount necessary for moving the connecting conductor 2a. Only on the 3 side, remove the connecting conductor 2a upward, move the connecting conductor 2a to the next tap centering on the butterfly nut 4, and tighten the nuts 3 and 4.

【考案の効果】[Effect of device]

本考案によれば、次のような効果がある。 (1)タップ切換えが容易でやりやすいので、タップ切換え作業に掛る手間を大 幅に削減することができる。 (2)タップ切換え作業に特別の工具を必要とせず、ちょうナットや、接続導体 が完全に脱離することもないので、油中へ異物を混入する恐れがない。 The present invention has the following effects. (1) Since tap switching is easy and easy, it is possible to greatly reduce the time and effort required for tap switching work. (2) No special tool is required for tap switching work, and neither the nut nor the connecting conductor is completely detached, so there is no risk of foreign matter entering the oil.
