本案は円筒形の高圧カットアウトに於いて下部電極の変

過熱を生じたりすることの無い様にした考案である。[Detailed explanation of the invention] This invention is a cylindrical high-voltage cutout that prevents the fuse tube from falling due to deformation of the lower electrode or causing overheating at the welded part with the electrode. be.
第1図に示す様な円筒形お高圧カットアウトに於いては
ヒユーズ筒1には下部に可動電極2を設はカットアウト
本体の碍子3の下部死損には集電板4を取付けて之に下
部固定電極3をリベット6で固着し以ってヒユーズ筒1
を可動電極2と固定電極5との圧接力で保持すること周
知の通りである。In a cylindrical high-voltage cutout as shown in Figure 1, a movable electrode 2 is installed at the bottom of the fuse tube 1, and a current collector plate 4 is attached to the dead bottom of the insulator 3 of the cutout body. Fix the lower fixed electrode 3 with the rivet 6, and then attach the fuse tube 1.
It is well known that the movable electrode 2 and the fixed electrode 5 are held together by pressure contact force.
此のヒユーズ筒1の挿脱は従って下部固定電極5の開閉
は長期間の中には数多く繰返えし行われるばかりでなく
時には乱暴な開閉操作が行なわれることがあり又大電流
の遮断時には大きな偏圧を受けるので固定電極5,5に
第4図示の如き開きの変形を生じ其の結果ヒユーズ筒の
保持力に低下を来たして固定電極5との接触部に過熱を
生じたり或はヒユーズ筒自体が落下する等の欠陥がある
。The insertion and removal of the fuse tube 1 and the opening and closing of the lower fixed electrode 5 are not only repeated many times over a long period of time, but also may be performed violently, and when a large current is interrupted. Since the fixed electrodes 5, 5 are subjected to a large uneven pressure, the fixed electrodes 5, 5 are deformed to open as shown in the fourth figure, and as a result, the holding force of the fuse cylinder is reduced, causing overheating at the contact part with the fixed electrode 5, or the fuse There are defects such as the tube itself falling off.
本案はかかる欠陥を極めて簡単安価の装置を以って防止
したものである。The present invention prevents such defects using an extremely simple and inexpensive device.
本案を実施例図面について説明する。The present invention will be explained with reference to embodiment drawings.
本案は集電板4を欠円形として其の下面に固定電極5,
5の外端部と固定電極の変形を阻止するための変形阻止
板7,7とを重合して前記リベット6で固着し且各阻止
板7の先端縁8,8は共に同一円周上にあらしめて相対
する固定電極5との間に一定のギャップaを作る。In this case, the current collector plate 4 is made into an occluded circle, and a fixed electrode 5 is placed on the lower surface of the current collector plate 4.
5 and deformation prevention plates 7, 7 for preventing deformation of the fixed electrode are overlapped and fixed with the rivet 6, and the tip edges 8, 8 of each prevention plate 7 are both on the same circumference. A certain gap a is then created between the opposing fixed electrodes 5.
そして此の一定のギャップaは該固定電極5の弾性限界
内に止める様に構成したものである。This constant gap a is configured to stay within the elastic limit of the fixed electrode 5.
上記本案の如く構成する時は長期間に互りヒユーズ筒1
の挿脱が行われても又其の挿脱に乱暴な開閉操作が行わ
れることがあっても更に又大電流遮断時に大きな偏圧が
加わることがあっても下部固定電極5は常に其の弾性限
界内に於いて阻止板7で阻止せられるので該固定電極5
の弾性力に低下を来たすことは無い。When configured as in the above proposal, the fuse tubes 1
The lower fixed electrode 5 always maintains its elasticity even if it is inserted and removed, even if rough opening/closing operations are performed during insertion and removal, and even if a large bias pressure is applied when a large current is cut off. Since it is blocked by the blocking plate 7 within the limit, the fixed electrode 5
There is no decrease in the elastic force of the material.
従って常にヒユーズ筒1を確実に保持するので従来の如
くヒユーズ筒が落下するとか或は接触部に過熱を生じる
とかの欠陥を生じることはない。Therefore, since the fuse tube 1 is always held securely, there are no defects such as the fuse tube falling or overheating of the contact portion as in the conventional case.
本案は極めて簡単安価の構造を以って上記効果を奏する
ので一層に有効である。The present invention is even more effective because it achieves the above effects with an extremely simple and inexpensive structure.
