列の安定状態のままで支持されている。 Therefore, most of the mass of the insulator device 1 of this invention is assumed to be occupied by the upper and lower insulator chains 1A, 1B, the guide member 14, and the vertical plumb 15. Then, the gravity applied to the insulator device 1 is defined as the gravity (W1) applied to the upper long-stem insulator strand 1A, the lower long-stem insulator strand 1B,
Gravity (W2
) (W2>W1), as shown in Figure 2, the gravity W1 of the upper long-stem insulator strand 1A arranged vertically, and the gravity of the lower long-stem insulator 1B and vertical plumb. The gravity W2 applied to 15 and the guide member 14 is:
The length of each arm is up to the upper long trunk insulator 1A.
l1 and arm length l2 (l2
>l1) and the insulator device 1 is not twisted. Therefore, the insulator device 1 is normally supported in a stable vertical arrangement.

W2 acts as a moment of force that resists the twisting of the device 1.

であるので、N2とN1との力のモーメントの差が
生じる。 That is, in this insulator device 1, as schematically shown in FIG. The moment of the force expressed by the product of the component F1 of the force acting perpendicular to l1 (assumed to be N1), N1 = F1 × l1 and the length l2 of the arm of the lower long insulator chain 1B, The moment of force (denoted as N2) represented by the product of the sum of the gravitational forces W2 applied to the insulator chain 1B, the vertical weight 15, and the guard member 14 and the component F2 of the force acting perpendicularly to the length l2 of the arm, N2 =F2×l2 acts, and since F2>F1 and l2>l1, a difference occurs in the moment of force between N2 and N1.
すなわち、
N=N2−N1>0

tries to return to its original stable state due to the reaction in the X direction.
以上力学的なモデルによつて説明したように、
この碍子装置1は風圧の力等が作用しても、碍子
装置1全体として捻回され難い。従つて、この碍
子装置1は安定した縦方向の配列状態が保たれ
る。 As explained above using the mechanical model,
This insulator device 1 is difficult to twist as a whole even when wind pressure or the like acts on it. Therefore, this insulator device 1 is maintained in a stable vertical alignment state.

なる。 However, in the unlikely event that an abnormal tension or an abnormal impact is applied to this insulator device 1, each connecting portion of the insulator device 1, for example, the axis P2 of the connecting portion between the conductor side yoke 2B and the upper long-stem insulator chain 1A, becomes separated. When cut, the upper long-stem insulator strings 1A, which were arranged in parallel, have the yokes 2A and 2B on the tower body side and the conductor side connected to the normal lower long-stem insulator strings 1B by the tension of the conductors, such as the axis P3, It will rotate around the axis H3 connecting P3. Then, the normal insulator chain 1B tries to move in the direction of the severed insulator chain 1A, while the severed insulator chain 1A tries to stay in its original position due to inertia. It will be in a pre-collision state with series 1A.

なつている。 At this time, as shown in FIG. 4, the separated insulator chain 1A is attached to the axis P2 of the connecting portion, or to the connecting portion between the right angle clevis link 8 and the horn fitting 6, or between the horn fitting 6 and the cap fitting 4. It rotates around the connecting part with the insulator chain 1B, and is in a state approaching the normal insulator chain 1B.

Then, the arc horn 7 has its annular creeping surface in contact with the guide member 14 and the guide member 14
furthermore, as shown in FIG.
direction). Therefore, the collision between the severed upper insulator chain 1A and the normal insulator chain 1B is avoided, and as a result, the normal lower insulator chain 1B is damaged and severed due to the collision with the severed upper insulator chain 1A. is prevented.
