Outside shape is flexure plane.The direction of guide pin 36, outer cover 38, the angle between 42 direction of connecting plate can be successfully as a result,
Change.
In addition, the external thread part 36a of guide pin 36 is also formed into the outside of outer cover 38 as shown in Fig. 5 (b) etc.,
Fixture nut 43 is installed on the external thread part 36a on the outside of this.By like this, installing fixture nut 43, it is suppressed that axis 32,
The case where guiding axis 33, guide cover 35 are largely and reversely to leave.Fixture nut is adjusted by being fastened and fixed nut 43
The distance between 43 and fastening nut 37 can apply initial load to cup spring 31, but as as aftermentioned, to cup spring
31 initial load utilizes the tension of adjustment bar 15, therefore can also not firmly be fastened and fixed nut 43.
Since the insulator arrangement 4 of present embodiment is single-column bearing pyrometric cone enhancing structure, therefore can be as shown in fig. 6
Like that, overall length is shortened in the operation for being carried out at the direction arrow D and rotating the adjustment bar 15 of adjustable overall length, apply as a result, to
The power (direction arrow A) of lower section stretching enforced insulator 12.The power for stretching the enforced insulator 12 downwards passes to damping
The cup spring 31 of device 30 compresses the cup spring 31 (direction arrow B).That is, as a result, as shown in Fig. 7 (a), due to downwards
The guide pin 36 connecting with adjustment bar 15 is stretched, therefore fixture nut 43 is reversely left with respect to outer cover 38, axis 32 moves downwards
It is dynamic, cup spring 31 is compressed, the initial load of authorized pressure is applied.
In addition, above-mentioned pulling force passes to enforced insulator 12 via damping device 30, impact operations branch identical as the past
Hold the pulling force (direction arrow B) of the compression direction of insulator 11 downward.Assign disconnecting switch integrally adequately
Tensioning state constitutes suitable rigidity, inhibits the displacement for being located at the conductive part 2 on the vertex of insulator arrangement 4.
In addition, in the occasion of the big taphrogeny with the stretching permissible value more than enforced insulator 12, as Fig. 8 institute
As showing, on the enforced insulator 12 for being located at the side opposite with the direction of vibration, the big drawing in the direction action arrow E
Stress.On the other hand, since in the enforced insulator 12 in the identical direction of vibration with conductive part 2, both ends are to pass through
Pin connection, thus pulling force becomes smaller and bending stress is small.In addition, if for example, the direction swung and conducting rod 6 are parallel, repeatedly
Ground generates the state of Fig. 8 (a) and the state of Fig. 8 (b).
In the occasion for the big pulling force for applying the direction arrow E to enforced insulator 12, opposite damping device 30, as Fig. 7
(b) as shown in, guide pin 36 is pulled downwards, and in the direction stretched upwards, to 42 active force of connecting plate.
With the situation, cup spring 31 compresses, and the pulling force acted on enforced insulator 12 is made to decay.Then, even if having big
In the case where taphrogeny, still can damping, can inhibit the swing of conductive part 2, can inhibit enforced insulator 12 resonate the case where,
Enforced insulator 12 be may also suppress nearby and the case where component contact.In addition, since the damping device 30 using cup spring 31 will
Small vibration caused by taphrogeny until big vibration is absorbed, therefore can more certainly inhibit conductive part 2 to vibrate
The case where.
In addition, in the present embodiment, since the lower end of damping device 30 connects with adjustment bar 15 via flexible arm 24
It connects, therefore also exponentially plays flexible arm bearing bring anti seismic efficiency.That is, if conductive part 2 is greatly because of big earthquake
It is subjected to displacement, then as shown in Fig. 9, damping device 30 shifts to top to enforced insulator 13 in turn.Then, flexible arm 24
It is operated in the way of lifting to top on the coupling part of the 1st arm 25 and the 2nd arm 26, seismic force thus can be made to disperse and decay.
At this point, since top is lifted in the coupling part, thus guide pin 36 moves on to top, in the direction for the compression for releasing cup spring 31
It is mobile, therefore more efficiently seismic force can be made to decay.
Even if in the disconnecting switch being arranged, enforced insulator and adjustment bar connection use by latch structure with
Enforced insulator lower end connection rod-shaped metalwork and carry out.The length of the metalwork has such as 80cm or so.In
It is, if the overall length for forming damping device is less than the scheme (for example, 60cm) of the length of the metalwork, to be preferably arranged
