一种断路器触头灭弧系统改良结构
摘要：
一种断路器触头灭弧系统改良结构，它包括灭弧室(1)，互相配合的动触头(2)和静触头(3)，其特征在于：所述灭弧室(1)的灭弧栅片组(101)的脚部(101a)被第一产气罩(4)包裹，第一产气罩(4)上与灭弧栅片组(101)的灭弧栅片对应处设有窄缝(401)以增大产气面积同时拉长电弧。本实用新型在第一产气罩(4)上增加窄缝增大产气面积同时拉长电弧，缩短电弧被灭弧栅片冷却后熄灭的时间，从而提高分段性能。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model provides a circuit breaker arc -Quenching system improves structure, it includes explosion chamber (1), mutual matched with moving contact (2) and static contact (3), its characterized in that: the foot (101a) of the arc extinguishing bars piece of explosion chamber (1) group (101) is by first products gas hood (4) parcel, and first product gas hood (4) is gone up and is equippedwith narrow slit (401) with the arc extinguishing bars piece department of correspondence of arc extinguishing bars piece group (101) and elongates electric arc simultaneously in order to increase product gas area. The utility model discloses increase narrow slit increase product gas area and elongate electric arc simultaneously on first product gas hood (4), shorten the time of extinguishing after electric arc is cooled off by arc extinguishing bars piece to improve the segmentation performance.
