Kind Code:
A1
Abstract:
An arc extinguishing apparatus (100) and a circuit breaker (200) comprising the same. The arc extinguishing apparatus (100) comprises: a stationary contact (10), a movable contact (20), an arc chute assembly (30), a first side plate (50), a second side plate (60) and a gas-producing assembly (40). The stationary contact (10) includes a stationary contact point (104), while the movable contact (20) consists of a movable contact point (202) adapted to mate with the stationary contact point (104). The arc chute assembly (30) is positioned above the stationary contact (10) and includes stacked arc chutes (302), wherein each arc chute (302) includes a base (301), a first arm (304) and a second arm (306), wherein the first and second arms (304,306) extend along two opposite sides of the base (301) and partially surround the stationary contact point (104). The first and second side plates (50,60)are made of insulating materials and coupled at two sides of the arc chute assembly (30) to fix the stacked arc chutes (302). The gas-producing assembly (40) includes a first clamping portion (402) and a second clamping portion (404) made of insulating materials, wherein the first clamping portion (402) clamps and isolates the end of the respective first arm (304) and the second clamping portion (404) clamps and isolates the end of the respective second arm (306).The arc extinguishing apparatus (100) can enhance the arc extinguishing performance by a simple structure and implement AC/DC universal purpose.
