Abstract
The invention relates to a contact assembly for improving breaking capacity of an arc extinguish chamber and the arc extinguish chamber. The contact assembly comprises a movable contact and a static contact, wherein at least two movable contact cutting grooves for cutting the movable contacts into movable contact petals with the corresponding number are formed in the movable contact along the circumferential direction; at least two static contact cutting grooves for cutting the static contacts into static contact petals with the corresponding number are formed in the static contact along the circumferential direction; and one movable contact petal stretches across at least two static contact petals along the circumferential direction and/or one static contact petal stretches across at least two movable contact petals along the circumferential direction. When the movable contact and the static contact are switched off, the current circuit between the movable contact and the static contact is doubled, namely, the number of fractures is increased, so that the current breaking capacity is improved; and in addition, after the current circuit is doubled, the surrounding magnetic field becomes more uniform, so that the breaking capacity is further improved.
