本発明は短絡電流等の大電流が流れた際、回路をしヤ断
する回路しゃ断器に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a circuit breaker that breaks a circuit when a large current such as a short circuit current flows.
この種、回路しゃ断器に於てはそのリンク機構の均整の
崩れによって閉極状態全開極状態にしている。In this type of circuit breaker, the link mechanism is out of balance, causing the circuit breaker to go from a closed state to a fully open state.
而して、そのリンク機構の応答性が遅く、接触子の高速
開極、ひいては高速限流しゃ断が行えなかった。Therefore, the response of the link mechanism was slow, and the contactor could not be opened at high speed, and furthermore, the current limiter could not be cut off at high speed.
特に、高定格容量の大型しゃ断器に於てはその傾向が顕
著である。This tendency is particularly noticeable in large circuit breakers with high rated capacities.
また、接触子部に平行電路を形成して接触子Vこ電磁反
発力を作用せしめて高速開極せしVるものにあっては接
点の開閉による接点の表面状1mlの違いによってその
動作点が著しく変化する欠点があった。In addition, in the case of a device that forms a parallel electric path in the contactor part and applies electromagnetic repulsion to the contactor to open the contact at high speed, the operating point may be affected by a 1ml difference in the surface condition of the contact due to the opening and closing of the contact. It had the disadvantage that it changed significantly.
更に、高定格容量の大型しゃ断器に於−Cは定格通電時
の発熱防止J:太きfL接点圧力を要し、そのためその
接点圧力に抗して反発するためには大きな反発力、ひい
ては犬蹴流を要し、従って動作点全かなり大きく設定し
なければならない欠点があった。Furthermore, in a large circuit breaker with a high rated capacity, -C requires a thick fL contact pressure to prevent heat generation when rated current is applied, and therefore a large repulsive force is required to resist the contact pressure and repel. There was a drawback that a kick flow was required, and therefore the operating point had to be set quite large.

Furthermore, an armature is arranged to perform a suction operation by this yoke, and the purpose of this armature is to instantaneously operate the movable contact plate one pole using one tension spring that serves both for contact pressure and for opening. It is.

る。As described above, the present invention includes a movable contact plate 9 having a movable contact 8 at the free end and supported by the proximal end shaft 10a, and a movable contact plate 9 having the movable contact 8 at the free end and the overcurrent operation terminal W connected to the proximal end of the movable contact plate 9. The evil that comes into contact:
A large flow (
(Becomes a yoke of magnetic flux due to
A magnetic arm 11 that supports the base end vehicle 10 and rotates around the base end shaft 13 using the handle 24; the armature 14 facing the base end of the arm 11, the free end 9a of the movable contact plate 9, and the free end 14 of the armature 14.
A tension spring 16 is suspended between the tension spring 16 and the tension spring 16.
Since the free end 14b of the armature 14 is attracted to the arm 11 so that it is located on the closing side from the shaft 101 point at the base end of the movable contact plate 9, and on the opening side when turned off, one The tension spring 16 can be used for both contact pressure and opening, and the spring 16 acts in the same direction as the attracting direction of the armature 14 from a certain point when opening the armature. This solves the problem of delay in opening the link mechanism, and can support high-rated circuit breakers.
