Detailed description of the invention
The conducting system current limliting of a kind of case circuit breaker related to this utility model below with reference to Figure of description scolds the technical scheme of opening apparatus to be described in further detail.
Referring to shown in Fig. 1, a conducting system current limliting that embodiment there is provided a kind of case circuit breaker of the present utility model scolds opening apparatus, it includes static contact 1, increases magnetic sheet 2, insulating trip 3, contact 4, moving contact 5, arc insulating apparatus 6, rotating shaft 7, locating shaft 8, wire folder 9, copper clip 10, thermal element 11, spring support 12 and stage clip 13.
Wherein said contact 4 is welded on described static contact 1 front end, described increasing magnetic sheet 2 is put in described insulating trip 3 and puts into the U-shaped spacing place of described static contact 1, described contact 4 is welded on described moving contact 5 front end, described arc insulating apparatus 6 is assemblied in the middle part of described moving contact 5 leading portion in spacing hole, and described moving contact 5 is located at described rotating shaft 7 realizing middle limiting groove and is positioned with told locating shaft 8.
